include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files. percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.
2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.
3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

ahci: add 43-bit DMA address quirk for ASMedia ASM1061 controllers
With one of the on-board ASM1061 AHCI controllers (1b21:0612) on an
ASUSTeK Pro WS WRX80E-SAGE SE WIFI mainboard, a controller hang was
observed that was immediately preceded by the following kernel
messages:
ahci 0000:28:00.0: Using 64-bit DMA addresses
ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00000 flags=0x0000]

ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00400 flags=0x0000]
ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00680 flags=0x0000]
ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00700 flags=0x0000]
The first message is produced by code in drivers/iommu/dma-iommu.c
which is accompanied by the following comment that seems to apply:
/*
* Try to use all the 32-bit PCI addresses first. The original SAC vs.
* DAC reasoning loses relevance with PCIe, but enough hardware and
* firmware bugs are still lurking out there that it's safest not to
* venture into the 64-bit space until necessary.
*
* If your device goes wrong after seeing the notice then likely either
* its driver is not setting DMA masks accurately, the hardware has
* some inherent bug in handling >32-bit addresses, or not all the
* expected address bits are wired up between the device and the IOMMU.
*/
Asking the ASM1061 on a discrete PCIe card to DMA from I/O virtual
address 0xffffffff00000000 produces the following I/O page faults:
vfio-pci 0000:07:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0021 address=0x7ff00000000 flags=0x0010]
vfio-pci 0000:07:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0021 address=0x7ff00000500 flags=0x0010]
Note that the upper 21 bits of the logged DMA address are zero. (When
asking a different PCIe device in the same PCIe slot to DMA to the
same I/O virtual address, we do see all the upper 32 bits of the DMA
address as 1, so this is not an issue with the chipset or IOMMU
configuration on the test system.)
Also, hacking libahci to always set the upper 21 bits of all DMA
addresses to 1 produces no discernible effect on the behavior of the
ASM1061, and mkfs/mount/scrub/etc work as without this hack.
This all strongly suggests that the ASM1061 has a 43 bit DMA address
limit, and this commit therefore adds a quirk to deal with this limit.
This issue probably applies to (some of) the other supported ASMedia
parts as well, but we limit it to the PCI IDs known to refer to
ASM1061 parts, as that's the only part we know for sure to be affected
by this issue at this point.

ahci: clean up intel_pcs_quirk
The comment in front of board_ahci_pcs7 is completely wrong.
It claims that board_ahci_pcs7 is needing the quirk, but in fact,
the logic implemented in ahci_intel_pcs_quirk() is the exact opposite,
only board_ahci_pcs7 is _excluded_ from the quirk.
This way of implementing a quirk is unconventional in several ways:
First of all because it has a board ID for which the quirk should _not_ be
applied (board_ahci_pcs7), instead of the usual way where we have a board
ID for which the quirk should be applied.
The second reason is that other than only excluding board_ahci_pcs7 from
the quirk, PCI devices that make use of the generic entry in ahci_pci_tbl
(which matches on AHCI class code) are also excluded.
This can of course lead to very subtle breakage, and did indeed do so in:
commit 104ff59af73a ("ata: ahci: Add Tiger Lake UP{3,4} AHCI controller"),
which added an explicit entry with board_ahci_low_power to ahci_pci_tbl.
This caused many users to complain that their SATA drives disappeared.
The logical assumption was of course that the issue was related to LPM,
and was therefore reverted in commit 6210038aeaf4 ("ata: ahci: Revert
"ata: ahci: Add Tiger Lake UP{3,4} AHCI controller"").
It took a lot of time to figure out that this was all completely unrelated
to LPM, and was instead caused by an unconventional Intel quirk.
Clean up the quirk so that it behaves like other quirks, i.e. define a
board where the quirk is applied. Platforms that were using
board_ahci_pcs7 are converted to use board_ahci, this is safe since the
boards were identical, and board_ahci_pcs7 did not define any custom
port_ops.
This way, new Intel platforms can be added using the correct "board_ahci"
board, without getting any unexpected quirks applied.
This means that we currently have some modern platforms defined that are
using the Intel PCS quirk, but that is identical to the behavior that
was there before this commit.
No functional changes intended.

libata: make reset related methods proper port operations
Currently reset methods are not specified directly in the
ata_port_operations table. If a LLD wants to use custom reset
methods, it should construct and use a error_handler which uses those
reset methods. It's done this way for two reasons.
First, the ops table already contained too many methods and adding
four more of them would noticeably increase the amount of necessary
boilerplate code all over low level drivers.
Second, as ->error_handler uses those reset methods, it can get
confusing. ie. By overriding ->error_handler, those reset ops can be
made useless making layering a bit hazy.
Now that ops table uses inheritance, the first problem doesn't exist
anymore. The second isn't completely solved but is relieved by
providing default values - most drivers can just override what it has
implemented and don't have to concern itself about higher level
callbacks. In fact, there currently is no driver which actually
modifies error handling behavior. Drivers which override
->error_handler just wraps the standard error handler only to prepare
the controller for EH. I don't think making ops layering strict has
any noticeable benefit.
This patch makes ->prereset, ->softreset, ->hardreset, ->postreset and
their PMP counterparts propoer ops. Default ops are provided in the
base ops tables and drivers are converted to override individual reset
methods instead of creating custom error_handler.
* ata_std_error_handler() doesn't use sata_std_hardreset() if SCRs
aren't accessible. sata_promise doesn't need to use separate
error_handlers for PATA and SATA anymore.
* softreset is broken for sata_inic162x and sata_sx4. As libata now
always prefers hardreset, this doesn't really matter but the ops are
forced to NULL using ATA_OP_NULL for documentation purpose.
* pata_hpt374 needs to use different prereset for the first and second
PCI functions. This used to be done by branching from
hpt374_error_handler(). The proper way to do this is to use
separate ops and port_info tables for each function. Converted.

libata: implement and use ops inheritance
libata lets low level drivers build ata_port_operations table and
register it with libata core layer. This allows low level drivers
high level of flexibility but also burdens them with lots of
boilerplate entries.
This becomes worse for drivers which support related similar
controllers which differ slightly. They share most of the operations
except for a few. However, the driver still needs to list all
operations for each variant. This results in large number of
duplicate entries, which is not only inefficient but also error-prone
as it becomes very difficult to tell what the actual differences are.
This duplicate boilerplates all over the low level drivers also make
updating the core layer exteremely difficult and error-prone. When
compounded with multi-branched development model, it ends up
accumulating inconsistencies over time. Some of those inconsistencies
cause immediate problems and fixed. Others just remain there dormant
making maintenance increasingly difficult.
To rectify the problem, this patch implements ata_port_operations
inheritance. To allow LLDs to easily re-use their own ops tables
overriding only specific methods, this patch implements poor man's
class inheritance. An ops table has ->inherits field which can be set
to any ops table as long as it doesn't create a loop. When the host
is started, the inheritance chain is followed and any operation which
isn't specified is taken from the nearest ancestor which has it
specified. This operation is called finalization and done only once
per an ops table and the LLD doesn't have to do anything special about
it other than making the ops table non-const such that libata can
update it.
libata provides four base ops tables lower drivers can inherit from -
base, sata, pmp, sff and bmdma. To avoid overriding these ops
accidentaly, these ops are declared const and LLDs should always
inherit these instead of using them directly.
After finalization, all the ops table are identical before and after
the patch except for setting .irq_handler to ata_interrupt in drivers
which didn't use to. The .irq_handler doesn't have any actual effect
and the field will soon be removed by later patch.
* sata_sx4 is still using old style EH and currently doesn't take
advantage of ops inheritance.

updating the core layer exteremely difficult and error-prone. When
compounded with multi-branched development model, it ends up
accumulating inconsistencies over time. Some of those inconsistencies
cause immediate problems and fixed. Others just remain there dormant
making maintenance increasingly difficult.
To rectify the problem, this patch implements ata_port_operations
inheritance. To allow LLDs to easily re-use their own ops tables
overriding only specific methods, this patch implements poor man's
class inheritance. An ops table has ->inherits field which can be set
to any ops table as long as it doesn't create a loop. When the host
is started, the inheritance chain is followed and any operation which
isn't specified is taken from the nearest ancestor which has it
specified. This operation is called finalization and done only once
per an ops table and the LLD doesn't have to do anything special about
it other than making the ops table non-const such that libata can
update it.
libata provides four base ops tables lower drivers can inherit from -
base, sata, pmp, sff and bmdma. To avoid overriding these ops
accidentaly, these ops are declared const and LLDs should always
inherit these instead of using them directly.
After finalization, all the ops table are identical before and after
the patch except for setting .irq_handler to ata_interrupt in drivers
which didn't use to. The .irq_handler doesn't have any actual effect
and the field will soon be removed by later patch.
* sata_sx4 is still using old style EH and currently doesn't take
advantage of ops inheritance.

ahci: add 43-bit DMA address quirk for ASMedia ASM1061 controllers
With one of the on-board ASM1061 AHCI controllers (1b21:0612) on an
ASUSTeK Pro WS WRX80E-SAGE SE WIFI mainboard, a controller hang was
observed that was immediately preceded by the following kernel
messages:
ahci 0000:28:00.0: Using 64-bit DMA addresses
ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00000 flags=0x0000]
ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00300 flags=0x0000]
ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00380 flags=0x0000]
ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00400 flags=0x0000]
ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00680 flags=0x0000]
ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00700 flags=0x0000]
The first message is produced by code in drivers/iommu/dma-iommu.c
which is accompanied by the following comment that seems to apply:
/*
* Try to use all the 32-bit PCI addresses first. The original SAC vs.
* DAC reasoning loses relevance with PCIe, but enough hardware and
* firmware bugs are still lurking out there that it's safest not to
* venture into the 64-bit space until necessary.
*
* If your device goes wrong after seeing the notice then likely either
* its driver is not setting DMA masks accurately, the hardware has
* some inherent bug in handling >32-bit addresses, or not all the
* expected address bits are wired up between the device and the IOMMU.
*/
Asking the ASM1061 on a discrete PCIe card to DMA from I/O virtual
address 0xffffffff00000000 produces the following I/O page faults:
vfio-pci 0000:07:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0021 address=0x7ff00000000 flags=0x0010]
vfio-pci 0000:07:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0021 address=0x7ff00000500 flags=0x0010]
Note that the upper 21 bits of the logged DMA address are zero. (When
asking a different PCIe device in the same PCIe slot to DMA to the
same I/O virtual address, we do see all the upper 32 bits of the DMA
address as 1, so this is not an issue with the chipset or IOMMU
configuration on the test system.)
Also, hacking libahci to always set the upper 21 bits of all DMA
addresses to 1 produces no discernible effect on the behavior of the
ASM1061, and mkfs/mount/scrub/etc work as without this hack.
This all strongly suggests that the ASM1061 has a 43 bit DMA address
limit, and this commit therefore adds a quirk to deal with this limit.
This issue probably applies to (some of) the other supported ASMedia
parts as well, but we limit it to the PCI IDs known to refer to
ASM1061 parts, as that's the only part we know for sure to be affected
by this issue at this point.

ahci: clean up intel_pcs_quirk
The comment in front of board_ahci_pcs7 is completely wrong.
It claims that board_ahci_pcs7 is needing the quirk, but in fact,
the logic implemented in ahci_intel_pcs_quirk() is the exact opposite,
only board_ahci_pcs7 is _excluded_ from the quirk.
This way of implementing a quirk is unconventional in several ways:
First of all because it has a board ID for which the quirk should _not_ be
applied (board_ahci_pcs7), instead of the usual way where we have a board
ID for which the quirk should be applied.
The second reason is that other than only excluding board_ahci_pcs7 from
the quirk, PCI devices that make use of the generic entry in ahci_pci_tbl
(which matches on AHCI class code) are also excluded.
This can of course lead to very subtle breakage, and did indeed do so in:
commit 104ff59af73a ("ata: ahci: Add Tiger Lake UP{3,4} AHCI controller"),
which added an explicit entry with board_ahci_low_power to ahci_pci_tbl.
This caused many users to complain that their SATA drives disappeared.
The logical assumption was of course that the issue was related to LPM,
and was therefore reverted in commit 6210038aeaf4 ("ata: ahci: Revert
"ata: ahci: Add Tiger Lake UP{3,4} AHCI controller"").
It took a lot of time to figure out that this was all completely unrelated
to LPM, and was instead caused by an unconventional Intel quirk.
Clean up the quirk so that it behaves like other quirks, i.e. define a
board where the quirk is applied. Platforms that were using
board_ahci_pcs7 are converted to use board_ahci, this is safe since the
boards were identical, and board_ahci_pcs7 did not define any custom
port_ops.
This way, new Intel platforms can be added using the correct "board_ahci"
board, without getting any unexpected quirks applied.
This means that we currently have some modern platforms defined that are
using the Intel PCS quirk, but that is identical to the behavior that
was there before this commit.
No functional changes intended.

PCI: Disable async suspend/resume for JMicron multi-function SATA/AHCI
On multi-function JMicron SATA/PATA/AHCI devices, the PATA controller at
function 1 doesn't work if it is powered on before the SATA controller at
function 0. The result is that PATA doesn't work after resume, and we
print messages like this:
pata_jmicron 0000:02:00.1: Refused to change power state, currently in D3
irq 17: nobody cared (try booting with the "irqpoll" option)
Async resume was introduced in v3.15 by 76569faa62c4 ("PM / sleep:
Asynchronous threads for resume_noirq"). Prior to that, we powered on
the functions in order, so this problem shouldn't happen.
e6b7e41cdd8c ("ata: Disabling the async PM for JMicron chip 363/361")
solved the problem for JMicron 361 and 363 devices. With async suspend
disabled, we always power on function 0 before function 1.
Barto then reported the same problem with a JMicron 368 (see comment #57 in
the bugzilla).
Rather than extending the blacklist piecemeal, disable async suspend for
all JMicron multi-function SATA/PATA/AHCI devices.
This quirk could stay in the ahci and pata_jmicron drivers, but it's likely
the problem will occur even if pata_jmicron isn't loaded until after the
suspend/resume. Making it a PCI quirk ensures that we'll preserve the
power-on order even if the drivers aren't loaded.

ata: ahci: Skip 200 ms debounce delay for Marvell 88SE9235
The 200 ms delay before debouncing the PHY in `sata_link_resume()` is
not needed for the Marvell 88SE9235.
$ lspci -nn -s 0021:0e:00.0

ahci: add 43-bit DMA address quirk for ASMedia ASM1061 controllers
With one of the on-board ASM1061 AHCI controllers (1b21:0612) on an
ASUSTeK Pro WS WRX80E-SAGE SE WIFI mainboard, a controller hang was
observed that was immediately preceded by the following kernel
messages:
ahci 0000:28:00.0: Using 64-bit DMA addresses
ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00000 flags=0x0000]

ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00700 flags=0x0000]
The first message is produced by code in drivers/iommu/dma-iommu.c
which is accompanied by the following comment that seems to apply:
/*
* Try to use all the 32-bit PCI addresses first. The original SAC vs.
* DAC reasoning loses relevance with PCIe, but enough hardware and
* firmware bugs are still lurking out there that it's safest not to
* venture into the 64-bit space until necessary.
*
* If your device goes wrong after seeing the notice then likely either
* its driver is not setting DMA masks accurately, the hardware has
* some inherent bug in handling >32-bit addresses, or not all the
* expected address bits are wired up between the device and the IOMMU.
*/
Asking the ASM1061 on a discrete PCIe card to DMA from I/O virtual
address 0xffffffff00000000 produces the following I/O page faults:
vfio-pci 0000:07:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0021 address=0x7ff00000000 flags=0x0010]
vfio-pci 0000:07:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0021 address=0x7ff00000500 flags=0x0010]
Note that the upper 21 bits of the logged DMA address are zero. (When
asking a different PCIe device in the same PCIe slot to DMA to the
same I/O virtual address, we do see all the upper 32 bits of the DMA
address as 1, so this is not an issue with the chipset or IOMMU
configuration on the test system.)
Also, hacking libahci to always set the upper 21 bits of all DMA
addresses to 1 produces no discernible effect on the behavior of the
ASM1061, and mkfs/mount/scrub/etc work as without this hack.
This all strongly suggests that the ASM1061 has a 43 bit DMA address
limit, and this commit therefore adds a quirk to deal with this limit.
This issue probably applies to (some of) the other supported ASMedia
parts as well, but we limit it to the PCI IDs known to refer to
ASM1061 parts, as that's the only part we know for sure to be affected
by this issue at this point.

ata: ahci: Add mask_port_map module parameter
Commits 0077a504e1a4 ("ahci: asm1166: correct count of reported ports")
and 9815e3961754 ("ahci: asm1064: correct count of reported ports")
attempted to limit the ports of the ASM1166 and ASM1064 AHCI controllers
to avoid long boot times caused by the fact that these adapters report
a port map larger than the number of physical ports. The excess ports
are "virtual" to hide port multiplier devices and probing these ports
takes time. However, these commits caused a regression for users that do

scanned. These commits have thus been reverted by commit 6cd8adc3e18
("ahci: asm1064: asm1166: don't limit reported ports") to allow the
discovery of devices connected through a port multiplier. But this

This patch adds the mask_port_map ahci module parameter to allow users

multiplier devices can mask the excess virtual ports exposed by the

- mask_port_map=<mask>
This applies the same mask to all AHCI controllers
present in the system. This format is convenient for small systems
that have only a single AHCI controller.
- mask_port_map=<pci_dev>=<mask>,<pci_dev>=mask,...
This applies the specified masks only to the PCI device listed. The
<pci_dev> field is a regular PCI device ID (domain:bus:dev.func).
This ID can be seen following "ahci" in the kernel messages. E.g.
for "ahci 0000:01:00.0: 2/2 ports implemented (port mask 0x3)", the
<pci_dev> field is "0000:01:00.0".
When used, the function ahci_save_initial_config() indicates that a
port map mask was applied with the message "masking port_map ...".
E.g.: without a mask:
modprobe ahci
dmesg | grep ahci
...
ahci 0000:00:17.0: AHCI vers 0001.0301, 32 command slots, 6 Gbps, SATA mode
ahci 0000:00:17.0: (0000:00:17.0) 8/8 ports implemented (port mask 0xff)
With a mask:
modprobe ahci mask_port_map=0000:00:17.0=0x1
dmesg | grep ahci
...
ahci 0000:00:17.0: masking port_map 0xff -> 0x1
ahci 0000:00:17.0: AHCI vers 0001.0301, 32 command slots, 6 Gbps, SATA mode
ahci 0000:00:17.0: (0000:00:17.0) 1/8 ports implemented (port mask 0x1)

ata: ahci: Allow ignoring the external/hotplug capability of ports
Commit 4edf1505b76d ("ata: ahci: Disallow LPM policy control for
external ports") introduced disabling link power management (LPM) for
ports that are advertized as external/hotplug capable. This is necessary
to force the maximum power policy (ATA_LPM_MAX_POWER) onto the port link
to ensure that the hotplug capability of the port is functional.
However, doing so blindly for all ports can prevent systems from going
into a low power state, even if the external/hotplug ports on the system
are unused. E.g., a laptop may see the internal SATA slot of a docking
station as an external hotplug capable port, and in such case, the user
may prefer to not use the port and to favor instead enabling LPM
to allow the laptop to transition to low power states.
Since there is no easy method to automatically detect such choice,
introduce the new mask_port_ext module parameter to allow a user to
ignore the external/hotplug capability of a port. The format for this
parameter value is identical to the format used for the mask_port_map
parameter: a mask can be defined for all AHCI adapters of a system or
for a particular adapters identified with their PCI IDs (bus:dev.func
format).
The function ahci_get_port_map_mask() is renamed to ahci_get_port_mask()
and modified to return a mask, either for the port map mask of an
adapter (to ignore ports) or for the external/hotplug capability of an
adapter. Differentiation between map_port_mask and map_port_ext_mask is
done by passing the parameter string to ahci_get_port_mask() as a second
argument.
To be consistent with this change, the function
ahci_apply_port_map_mask() is renamed ahci_port_mask() and changed to
return a mask value.
The mask for the external/hotplug capability for an adapter, if defined
by the map_port_ext_mask parameter, is stored in the new field
mask_port_ext of struct ahci_host_priv. ahci_mark_external_port() is
modified to not set the ATA_PFLAG_EXTERNAL flag for a port if
hpriv->mask_port_ext includes the number of the port. In such case,
an information message is printed to notify that the external/hotplug
capability is being ignored.

station as an external hotplug capable port, and in such case, the user
may prefer to not use the port and to favor instead enabling LPM
to allow the laptop to transition to low power states.
Since there is no easy method to automatically detect such choice,
introduce the new mask_port_ext module parameter to allow a user to
ignore the external/hotplug capability of a port. The format for this
parameter value is identical to the format used for the mask_port_map
parameter: a mask can be defined for all AHCI adapters of a system or
for a particular adapters identified with their PCI IDs (bus:dev.func
format).
The function ahci_get_port_map_mask() is renamed to ahci_get_port_mask()
and modified to return a mask, either for the port map mask of an
adapter (to ignore ports) or for the external/hotplug capability of an
adapter. Differentiation between map_port_mask and map_port_ext_mask is
done by passing the parameter string to ahci_get_port_mask() as a second
argument.
To be consistent with this change, the function
ahci_apply_port_map_mask() is renamed ahci_port_mask() and changed to
return a mask value.
The mask for the external/hotplug capability for an adapter, if defined
by the map_port_ext_mask parameter, is stored in the new field
mask_port_ext of struct ahci_host_priv. ahci_mark_external_port() is
modified to not set the ATA_PFLAG_EXTERNAL flag for a port if
hpriv->mask_port_ext includes the number of the port. In such case,
an information message is printed to notify that the external/hotplug
capability is being ignored.

ata: ahci: Add mask_port_map module parameter
Commits 0077a504e1a4 ("ahci: asm1166: correct count of reported ports")
and 9815e3961754 ("ahci: asm1064: correct count of reported ports")
attempted to limit the ports of the ASM1166 and ASM1064 AHCI controllers
to avoid long boot times caused by the fact that these adapters report
a port map larger than the number of physical ports. The excess ports
are "virtual" to hide port multiplier devices and probing these ports
takes time. However, these commits caused a regression for users that do
use PMP devices, as the ATA devices connected to the PMP cannot be
scanned. These commits have thus been reverted by commit 6cd8adc3e18
("ahci: asm1064: asm1166: don't limit reported ports") to allow the
discovery of devices connected through a port multiplier. But this
revert re-introduced the long boot times for users that do not use a
port multiplier setup.
This patch adds the mask_port_map ahci module parameter to allow users
to manually specify port map masks for controllers. In the case of the
ASMedia 1166 and 1064 controllers, users that do not have port
multiplier devices can mask the excess virtual ports exposed by the
controller to speedup port scanning, thus reducing boot time.
The mask_port_map parameter accepts 2 different formats:
- mask_port_map=<mask>
This applies the same mask to all AHCI controllers
present in the system. This format is convenient for small systems
that have only a single AHCI controller.
- mask_port_map=<pci_dev>=<mask>,<pci_dev>=mask,...
This applies the specified masks only to the PCI device listed. The
<pci_dev> field is a regular PCI device ID (domain:bus:dev.func).
This ID can be seen following "ahci" in the kernel messages. E.g.
for "ahci 0000:01:00.0: 2/2 ports implemented (port mask 0x3)", the
<pci_dev> field is "0000:01:00.0".
When used, the function ahci_save_initial_config() indicates that a
port map mask was applied with the message "masking port_map ...".
E.g.: without a mask:
modprobe ahci
dmesg | grep ahci
...
ahci 0000:00:17.0: AHCI vers 0001.0301, 32 command slots, 6 Gbps, SATA mode
ahci 0000:00:17.0: (0000:00:17.0) 8/8 ports implemented (port mask 0xff)
With a mask:
modprobe ahci mask_port_map=0000:00:17.0=0x1
dmesg | grep ahci
...
ahci 0000:00:17.0: masking port_map 0xff -> 0x1
ahci 0000:00:17.0: AHCI vers 0001.0301, 32 command slots, 6 Gbps, SATA mode
ahci 0000:00:17.0: (0000:00:17.0) 1/8 ports implemented (port mask 0x1)

ata: ahci: Allow ignoring the external/hotplug capability of ports
Commit 4edf1505b76d ("ata: ahci: Disallow LPM policy control for
external ports") introduced disabling link power management (LPM) for
ports that are advertized as external/hotplug capable. This is necessary
to force the maximum power policy (ATA_LPM_MAX_POWER) onto the port link
to ensure that the hotplug capability of the port is functional.
However, doing so blindly for all ports can prevent systems from going
into a low power state, even if the external/hotplug ports on the system
are unused. E.g., a laptop may see the internal SATA slot of a docking
station as an external hotplug capable port, and in such case, the user
may prefer to not use the port and to favor instead enabling LPM

ata: ahci: Allow ignoring the external/hotplug capability of ports
Commit 4edf1505b76d ("ata: ahci: Disallow LPM policy control for

ports that are advertized as external/hotplug capable. This is necessary
to force the maximum power policy (ATA_LPM_MAX_POWER) onto the port link
to ensure that the hotplug capability of the port is functional.
However, doing so blindly for all ports can prevent systems from going
into a low power state, even if the external/hotplug ports on the system
are unused. E.g., a laptop may see the internal SATA slot of a docking
station as an external hotplug capable port, and in such case, the user
may prefer to not use the port and to favor instead enabling LPM
to allow the laptop to transition to low power states.
Since there is no easy method to automatically detect such choice,
introduce the new mask_port_ext module parameter to allow a user to
ignore the external/hotplug capability of a port. The format for this
parameter value is identical to the format used for the mask_port_map
parameter: a mask can be defined for all AHCI adapters of a system or
for a particular adapters identified with their PCI IDs (bus:dev.func
format).
The function ahci_get_port_map_mask() is renamed to ahci_get_port_mask()
and modified to return a mask, either for the port map mask of an
adapter (to ignore ports) or for the external/hotplug capability of an
adapter. Differentiation between map_port_mask and map_port_ext_mask is
done by passing the parameter string to ahci_get_port_mask() as a second
argument.
To be consistent with this change, the function
ahci_apply_port_map_mask() is renamed ahci_port_mask() and changed to
return a mask value.
The mask for the external/hotplug capability for an adapter, if defined
by the map_port_ext_mask parameter, is stored in the new field
mask_port_ext of struct ahci_host_priv. ahci_mark_external_port() is
modified to not set the ATA_PFLAG_EXTERNAL flag for a port if
hpriv->mask_port_ext includes the number of the port. In such case,

ata: ahci: Add mask_port_map module parameter
Commits 0077a504e1a4 ("ahci: asm1166: correct count of reported ports")
and 9815e3961754 ("ahci: asm1064: correct count of reported ports")
attempted to limit the ports of the ASM1166 and ASM1064 AHCI controllers
to avoid long boot times caused by the fact that these adapters report
a port map larger than the number of physical ports. The excess ports
are "virtual" to hide port multiplier devices and probing these ports
takes time. However, these commits caused a regression for users that do
use PMP devices, as the ATA devices connected to the PMP cannot be
scanned. These commits have thus been reverted by commit 6cd8adc3e18
("ahci: asm1064: asm1166: don't limit reported ports") to allow the
discovery of devices connected through a port multiplier. But this
revert re-introduced the long boot times for users that do not use a
port multiplier setup.
This patch adds the mask_port_map ahci module parameter to allow users
to manually specify port map masks for controllers. In the case of the
ASMedia 1166 and 1064 controllers, users that do not have port
multiplier devices can mask the excess virtual ports exposed by the
controller to speedup port scanning, thus reducing boot time.
The mask_port_map parameter accepts 2 different formats:
- mask_port_map=<mask>
This applies the same mask to all AHCI controllers
present in the system. This format is convenient for small systems
that have only a single AHCI controller.
- mask_port_map=<pci_dev>=<mask>,<pci_dev>=mask,...
This applies the specified masks only to the PCI device listed. The
<pci_dev> field is a regular PCI device ID (domain:bus:dev.func).
This ID can be seen following "ahci" in the kernel messages. E.g.
for "ahci 0000:01:00.0: 2/2 ports implemented (port mask 0x3)", the
<pci_dev> field is "0000:01:00.0".
When used, the function ahci_save_initial_config() indicates that a
port map mask was applied with the message "masking port_map ...".
E.g.: without a mask:
modprobe ahci
dmesg | grep ahci
...
ahci 0000:00:17.0: AHCI vers 0001.0301, 32 command slots, 6 Gbps, SATA mode

ata: ahci: Allow ignoring the external/hotplug capability of ports
Commit 4edf1505b76d ("ata: ahci: Disallow LPM policy control for
external ports") introduced disabling link power management (LPM) for
ports that are advertized as external/hotplug capable. This is necessary
to force the maximum power policy (ATA_LPM_MAX_POWER) onto the port link
to ensure that the hotplug capability of the port is functional.
However, doing so blindly for all ports can prevent systems from going
into a low power state, even if the external/hotplug ports on the system
are unused. E.g., a laptop may see the internal SATA slot of a docking
station as an external hotplug capable port, and in such case, the user
may prefer to not use the port and to favor instead enabling LPM
to allow the laptop to transition to low power states.
Since there is no easy method to automatically detect such choice,
introduce the new mask_port_ext module parameter to allow a user to
ignore the external/hotplug capability of a port. The format for this
parameter value is identical to the format used for the mask_port_map
parameter: a mask can be defined for all AHCI adapters of a system or
for a particular adapters identified with their PCI IDs (bus:dev.func
format).
The function ahci_get_port_map_mask() is renamed to ahci_get_port_mask()
and modified to return a mask, either for the port map mask of an
adapter (to ignore ports) or for the external/hotplug capability of an
adapter. Differentiation between map_port_mask and map_port_ext_mask is
done by passing the parameter string to ahci_get_port_mask() as a second
argument.
To be consistent with this change, the function
ahci_apply_port_map_mask() is renamed ahci_port_mask() and changed to
return a mask value.
The mask for the external/hotplug capability for an adapter, if defined
by the map_port_ext_mask parameter, is stored in the new field
mask_port_ext of struct ahci_host_priv. ahci_mark_external_port() is
modified to not set the ATA_PFLAG_EXTERNAL flag for a port if
hpriv->mask_port_ext includes the number of the port. In such case,
an information message is printed to notify that the external/hotplug
capability is being ignored.

ata: ahci: Add mask_port_map module parameter
Commits 0077a504e1a4 ("ahci: asm1166: correct count of reported ports")
and 9815e3961754 ("ahci: asm1064: correct count of reported ports")
attempted to limit the ports of the ASM1166 and ASM1064 AHCI controllers
to avoid long boot times caused by the fact that these adapters report
a port map larger than the number of physical ports. The excess ports
are "virtual" to hide port multiplier devices and probing these ports
takes time. However, these commits caused a regression for users that do
use PMP devices, as the ATA devices connected to the PMP cannot be
scanned. These commits have thus been reverted by commit 6cd8adc3e18
("ahci: asm1064: asm1166: don't limit reported ports") to allow the
discovery of devices connected through a port multiplier. But this
revert re-introduced the long boot times for users that do not use a
port multiplier setup.
This patch adds the mask_port_map ahci module parameter to allow users
to manually specify port map masks for controllers. In the case of the
ASMedia 1166 and 1064 controllers, users that do not have port
multiplier devices can mask the excess virtual ports exposed by the
controller to speedup port scanning, thus reducing boot time.
The mask_port_map parameter accepts 2 different formats:
- mask_port_map=<mask>
This applies the same mask to all AHCI controllers
present in the system. This format is convenient for small systems
that have only a single AHCI controller.
- mask_port_map=<pci_dev>=<mask>,<pci_dev>=mask,...
This applies the specified masks only to the PCI device listed. The
<pci_dev> field is a regular PCI device ID (domain:bus:dev.func).
This ID can be seen following "ahci" in the kernel messages. E.g.
for "ahci 0000:01:00.0: 2/2 ports implemented (port mask 0x3)", the
<pci_dev> field is "0000:01:00.0".
When used, the function ahci_save_initial_config() indicates that a
port map mask was applied with the message "masking port_map ...".
E.g.: without a mask:
modprobe ahci
dmesg | grep ahci
...
ahci 0000:00:17.0: AHCI vers 0001.0301, 32 command slots, 6 Gbps, SATA mode
ahci 0000:00:17.0: (0000:00:17.0) 8/8 ports implemented (port mask 0xff)
With a mask:
modprobe ahci mask_port_map=0000:00:17.0=0x1
dmesg | grep ahci
...
ahci 0000:00:17.0: masking port_map 0xff -> 0x1
ahci 0000:00:17.0: AHCI vers 0001.0301, 32 command slots, 6 Gbps, SATA mode
ahci 0000:00:17.0: (0000:00:17.0) 1/8 ports implemented (port mask 0x1)

libata: add deadline support to prereset and reset methods
Add @deadline to prereset and reset methods and make them honor it.
ata_wait_ready() which directly takes @deadline is implemented to be
used as the wait function. This patch is in preparation for EH timing
improvements.
* ata_wait_ready() never does busy sleep. It's only used from EH and
no wait in EH is that urgent. This function also prints 'be
patient' message automatically after 5 secs of waiting if more than
3 secs is remaining till deadline.
* ata_bus_post_reset() now fails with error code if any of its wait
fails. This is important because earlier reset tries will have
shorter timeout than the spec requires. If a device fails to
respond before the short timeout, reset should be retried with
longer timeout rather than silently ignoring the device.
There are three behavior differences.
1. Timeout is applied to both devices at once, not separately. This
is more consistent with what the spec says.
2. When a device passes devchk but fails to become ready before
deadline. Previouly, post_reset would just succeed and let
device classification remove the device. New code fails the
reset thus causing reset retry. After a few times, EH will give
up disabling the port.
3. When slave device passes devchk but fails to become accessible
(TF-wise) after reset. Original code disables dev1 after 30s
timeout and continues as if the device doesn't exist, while the
patched code fails reset. When this happens, new code fails
reset on whole port rather than proceeding with only the primary
device.
If the failing device is suffering transient problems, new code
retries reset which is a better behavior. If the failing device is
actually broken, the net effect is identical to it, but not to the
other device sharing the channel. In the previous code, reset would
have succeeded after 30s thus detecting the working one. In the new
code, reset fails and whole port gets disabled. IMO, it's a
pathological case anyway (broken device sharing bus with working
one) and doesn't really matter.
* ata_bus_softreset() is changed to return error code from
ata_bus_post_reset(). It used to return 0 unconditionally.
* Spin up waiting is to be removed and not converted to honor
deadline.
* To be on the safe side, deadline is set to 40s for the time being.

The first message is produced by code in drivers/iommu/dma-iommu.c
which is accompanied by the following comment that seems to apply:

Asking the ASM1061 on a discrete PCIe card to DMA from I/O virtual
address 0xffffffff00000000 produces the following I/O page faults:
vfio-pci 0000:07:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0021 address=0x7ff00000000 flags=0x0010]
vfio-pci 0000:07:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0021 address=0x7ff00000500 flags=0x0010]
Note that the upper 21 bits of the logged DMA address are zero. (When
asking a different PCIe device in the same PCIe slot to DMA to the
same I/O virtual address, we do see all the upper 32 bits of the DMA
address as 1, so this is not an issue with the chipset or IOMMU
configuration on the test system.)
Also, hacking libahci to always set the upper 21 bits of all DMA
addresses to 1 produces no discernible effect on the behavior of the
ASM1061, and mkfs/mount/scrub/etc work as without this hack.
This all strongly suggests that the ASM1061 has a 43 bit DMA address
limit, and this commit therefore adds a quirk to deal with this limit.
This issue probably applies to (some of) the other supported ASMedia
parts as well, but we limit it to the PCI IDs known to refer to
ASM1061 parts, as that's the only part we know for sure to be affected
by this issue at this point.

ahci: add 43-bit DMA address quirk for ASMedia ASM1061 controllers
With one of the on-board ASM1061 AHCI controllers (1b21:0612) on an
ASUSTeK Pro WS WRX80E-SAGE SE WIFI mainboard, a controller hang was
observed that was immediately preceded by the following kernel

ahci: Add generic MSI-X support for single interrupts to SATA PCI driver
This patch adds generic MSI-X support for single interrupts to the
SATA PCI driver. MSI-X support is needed for host controller that only
have MSI-X support implemented, but no MSI or intx. This patch only
adds support for single interrupts, multiple per-port MSI-X interrupts
are not yet implemented.
The new implementation still initializes MSIs first. Only if that
fails, the code tries to enable MSI-X. If that fails too, setup is
continued with intx interrupts.
To not break other chips by this generic code change, there are the
following precautions:
* Interrupt ranges are not enabled at all.
* Only single interrupt mode is enabled for msix cap devices. Thus,
only one interrupt will be setup.
* During the discussion with Tejun we agreed to change the init
sequence from msix-msi-intx to msi-msix-intx. Thus, if a device
offers msi and init does not fail, the msix init code will not be
executed. This is equivalent to current code.
With this, the code only setups single mode msix as a last resort if
msi fails. No interrupt range is enabled at all. Only one interrupt
will be enabled.
tj: comment edits.
Changes of the patch series:
v5:
* updated patch subject that the patch only implements single IRQ
* moved Cavium specific code to a separate patch
* detect Cavium ThunderX device with PCI_CLASS_STORAGE_SATA_AHCI
instead of vendor/dev id
* added more comments to the code
* enable single msix support for all kind of devices (removing strict
check)
* rebased onto update libata/for-4.2 with patch 1, 2 applied
v4:
* removed implementation of ahci_init_intx()
* improved patch descriptions
* rebased onto libata/for-4.2
v3:
* store irq number in struct ahci_host_priv
* change initialization order from msix-msi-intx to msi-msix-intx
* improve comments in ahci_init_msix()
* improve error message in ahci_init_msix()
* do not enable MSI-X if MSI is actively disabled for the device
v2:
* determine irq vector from pci_dev->msi_list
Based on a patch from Sunil Goutham <sgoutham@cavium.com>.

are not yet implemented.
The new implementation still initializes MSIs first. Only if that
fails, the code tries to enable MSI-X. If that fails too, setup is
continued with intx interrupts.
To not break other chips by this generic code change, there are the
following precautions:
* Interrupt ranges are not enabled at all.
* Only single interrupt mode is enabled for msix cap devices. Thus,
only one interrupt will be setup.
* During the discussion with Tejun we agreed to change the init
sequence from msix-msi-intx to msi-msix-intx. Thus, if a device
offers msi and init does not fail, the msix init code will not be
executed. This is equivalent to current code.
With this, the code only setups single mode msix as a last resort if
msi fails. No interrupt range is enabled at all. Only one interrupt
will be enabled.
tj: comment edits.
Changes of the patch series:
v5:
* updated patch subject that the patch only implements single IRQ
* moved Cavium specific code to a separate patch
* detect Cavium ThunderX device with PCI_CLASS_STORAGE_SATA_AHCI
instead of vendor/dev id
* added more comments to the code
* enable single msix support for all kind of devices (removing strict
check)
* rebased onto update libata/for-4.2 with patch 1, 2 applied
v4:
* removed implementation of ahci_init_intx()
* improved patch descriptions
* rebased onto libata/for-4.2
v3:
* store irq number in struct ahci_host_priv
* change initialization order from msix-msi-intx to msi-msix-intx
* improve comments in ahci_init_msix()
* improve error message in ahci_init_msix()
* do not enable MSI-X if MSI is actively disabled for the device
v2:

ata: ahci: Allow ignoring the external/hotplug capability of ports
Commit 4edf1505b76d ("ata: ahci: Disallow LPM policy control for
external ports") introduced disabling link power management (LPM) for
ports that are advertized as external/hotplug capable. This is necessary
to force the maximum power policy (ATA_LPM_MAX_POWER) onto the port link
to ensure that the hotplug capability of the port is functional.
However, doing so blindly for all ports can prevent systems from going
into a low power state, even if the external/hotplug ports on the system
are unused. E.g., a laptop may see the internal SATA slot of a docking
station as an external hotplug capable port, and in such case, the user
may prefer to not use the port and to favor instead enabling LPM
to allow the laptop to transition to low power states.
Since there is no easy method to automatically detect such choice,
introduce the new mask_port_ext module parameter to allow a user to
ignore the external/hotplug capability of a port. The format for this
parameter value is identical to the format used for the mask_port_map
parameter: a mask can be defined for all AHCI adapters of a system or
for a particular adapters identified with their PCI IDs (bus:dev.func
format).
The function ahci_get_port_map_mask() is renamed to ahci_get_port_mask()
and modified to return a mask, either for the port map mask of an
adapter (to ignore ports) or for the external/hotplug capability of an
adapter. Differentiation between map_port_mask and map_port_ext_mask is
done by passing the parameter string to ahci_get_port_mask() as a second
argument.
To be consistent with this change, the function
ahci_apply_port_map_mask() is renamed ahci_port_mask() and changed to
return a mask value.
The mask for the external/hotplug capability for an adapter, if defined
by the map_port_ext_mask parameter, is stored in the new field
mask_port_ext of struct ahci_host_priv. ahci_mark_external_port() is
modified to not set the ATA_PFLAG_EXTERNAL flag for a port if
hpriv->mask_port_ext includes the number of the port. In such case,
an information message is printed to notify that the external/hotplug
capability is being ignored.

ata: ahci: do not enable LPM on external ports
AHCI 1.3.3, 7.3.1.1 Software Flow for Hot Plug Removal Detection states:
"To reliably detect hot plug removals, software must disable interface
power management.
Software should perform the following initialization on a port after a
device is attached:
-Set PxSCTL.IPM to 3h to disable interface power management state
transitions.
-Set PxCMD.ALPE to ‘0’ to disable aggressive power management.
-Ensure PxIE.PRCE is set to ‘1’ to enable interrupts on hot plug removals.
-Disable device initiated interface power management by issuing the
appropriate SET FEATURES command."
Further, AHCI 1.3.3, 7.3 Native Hot Plug Support states:
"The HBA shall set the PxSERR.DIAG.X bit to ‘1’ when a COMINIT is received
from the device. Hot plug insertions are detected via the PxIS.PCS bit
that directly reflects the PxSERR.DIAG.X bit. The HBA shall set the
PxSERR.DIAG.N bit to ‘1’ when the HBA’s internal PhyRdy signal changes
state.
Hot plug removals are detected via the PxIS.PRCS bit that directly
reflects the PxSERR.DIAG.N bit. Note that PxSERR.DIAG.N is also set
to ‘1’ on insertions and during interface power management entry/exit."
ahci_set_lpm() already disables the PxIS.PRCS interrupt if setting a
LPM policy != ATA_LPM_MAX_POWER, so we cannot detect hot plug removals
when LPM policy != ATA_LPM_MAX_POWER.
We do have PxIS.PCS interrupt enabled even for LPM policy !=
ATA_LPM_MAX_POWER, so we should theoretically still be able to detect
hot plug insertions even when LPM is enabled.
However, in practise, for LPM policy ATA_LPM_MED_POWER_WITH_DIPM,
ATA_LPM_MIN_POWER_WITH_PARTIAL, and ATA_LPM_MIN_POWER, if there is
no link enabled, sata_link_scr_lpm() will set SControl.DET = 0x4,
which will transition the port to the "P:Offline" state.
The P:Offline mode is described in SATA Gold 3.5a:
4.1.1.103 Phy offline:
"In this mode the host Phy is forced off and the host Phy does not
recognize nor respond to COMINIT or COMWAKE. This mode is entered by
setting the DET field of the SControl register to 0100b. This is a
mechanism for the host to turn off its Phy."
So in the P:Offline state the PHY does not recognize the unsolicited
COMINIT which is sent on a hot plug insertion.
While we could change sata_link_scr_lpm() to never power off an external
port for LPM policy != ATA_LPM_MAX_POWER (in order be able to handle hot
plug insertions), we still would not be able to handle hot plug removals.
Thus, simply modify ahci_update_initial_lpm_policy() to not enable LPM if
the port advertises itself as an external port, as this function is
already being used to set/override the initial LPM policy.

ahci: clean up intel_pcs_quirk
The comment in front of board_ahci_pcs7 is completely wrong.
It claims that board_ahci_pcs7 is needing the quirk, but in fact,
the logic implemented in ahci_intel_pcs_quirk() is the exact opposite,
only board_ahci_pcs7 is _excluded_ from the quirk.
This way of implementing a quirk is unconventional in several ways:
First of all because it has a board ID for which the quirk should _not_ be
applied (board_ahci_pcs7), instead of the usual way where we have a board
ID for which the quirk should be applied.
The second reason is that other than only excluding board_ahci_pcs7 from
the quirk, PCI devices that make use of the generic entry in ahci_pci_tbl
(which matches on AHCI class code) are also excluded.
This can of course lead to very subtle breakage, and did indeed do so in:
commit 104ff59af73a ("ata: ahci: Add Tiger Lake UP{3,4} AHCI controller"),
which added an explicit entry with board_ahci_low_power to ahci_pci_tbl.
This caused many users to complain that their SATA drives disappeared.
The logical assumption was of course that the issue was related to LPM,
and was therefore reverted in commit 6210038aeaf4 ("ata: ahci: Revert
"ata: ahci: Add Tiger Lake UP{3,4} AHCI controller"").
It took a lot of time to figure out that this was all completely unrelated
to LPM, and was instead caused by an unconventional Intel quirk.
Clean up the quirk so that it behaves like other quirks, i.e. define a
board where the quirk is applied. Platforms that were using
board_ahci_pcs7 are converted to use board_ahci, this is safe since the
boards were identical, and board_ahci_pcs7 did not define any custom
port_ops.
This way, new Intel platforms can be added using the correct "board_ahci"
board, without getting any unexpected quirks applied.
This means that we currently have some modern platforms defined that are
using the Intel PCS quirk, but that is identical to the behavior that
was there before this commit.
No functional changes intended.

libata: convert the remaining SATA drivers to new init model
Convert ahci, sata_sil, sata_sil24, sata_svw, sata_qstor, sata_mv,
sata_sx4, sata_vsc and sata_inic162x to new init model.
Now that host and ap are available during intialization, functions are
converted to take either host or ap instead of low level parameters
which were inevitable for functions shared between init and other
paths. This simplifies code quite a bit.
* init_one()'s now follow more consistent init order
* ahci_setup_port() and ahci_host_init() collapsed into
ahci_init_one() for init order consistency
* sata_vsc uses port_info instead of setting fields manually
* in sata_svw, k2_board_info converted to port_info (info is now in
port flags). port number is honored now.
Tested on ICH7/8 AHCI, jmb360, sil3112, 3114, 3124 and 3132.

ata: libata: disallow dev-initiated LPM transitions to unsupported states
In AHCI 1.3.1, the register description for CAP.SSC:
"When cleared to ‘0’, software must not allow the HBA to initiate
transitions to the Slumber state via agressive link power management nor
the PxCMD.ICC field in each port, and the PxSCTL.IPM field in each port
must be programmed to disallow device initiated Slumber requests."
In AHCI 1.3.1, the register description for CAP.PSC:
"When cleared to ‘0’, software must not allow the HBA to initiate
transitions to the Partial state via agressive link power management nor
the PxCMD.ICC field in each port, and the PxSCTL.IPM field in each port
must be programmed to disallow device initiated Partial requests."
Ensure that we always set the corresponding bits in PxSCTL.IPM, such that
a device is not allowed to initiate transitions to power states which are
unsupported by the HBA.
DevSleep is always initiated by the HBA, however, for completeness, set the
corresponding bit in PxSCTL.IPM such that agressive link power management
cannot transition to DevSleep if DevSleep is not supported.
sata_link_scr_lpm() is used by libahci, ata_piix and libata-pmp.
However, only libahci has the ability to read the CAP/CAP2 register to see
if these features are supported. Therefore, in order to not introduce any
regressions on ata_piix or libata-pmp, create flags that indicate that the
respective feature is NOT supported. This way, the behavior for ata_piix
and libata-pmp should remain unchanged.
This change is based on a patch originally submitted by Runa Guo-oc.

Convert ahci, sata_sil, sata_sil24, sata_svw, sata_qstor, sata_mv,
sata_sx4, sata_vsc and sata_inic162x to new init model.
Now that host and ap are available during intialization, functions are
converted to take either host or ap instead of low level parameters
which were inevitable for functions shared between init and other
paths. This simplifies code quite a bit.
* init_one()'s now follow more consistent init order
* ahci_setup_port() and ahci_host_init() collapsed into
ahci_init_one() for init order consistency
* sata_vsc uses port_info instead of setting fields manually
* in sata_svw, k2_board_info converted to port_info (info is now in
port flags). port number is honored now.
Tested on ICH7/8 AHCI, jmb360, sil3112, 3114, 3124 and 3132.

ahci: add 43-bit DMA address quirk for ASMedia ASM1061 controllers
With one of the on-board ASM1061 AHCI controllers (1b21:0612) on an
ASUSTeK Pro WS WRX80E-SAGE SE WIFI mainboard, a controller hang was
observed that was immediately preceded by the following kernel
messages:
ahci 0000:28:00.0: Using 64-bit DMA addresses
ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00000 flags=0x0000]
ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00300 flags=0x0000]
ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00380 flags=0x0000]
ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00400 flags=0x0000]
ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00680 flags=0x0000]
ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00700 flags=0x0000]
The first message is produced by code in drivers/iommu/dma-iommu.c
which is accompanied by the following comment that seems to apply:
/*
* Try to use all the 32-bit PCI addresses first. The original SAC vs.
* DAC reasoning loses relevance with PCIe, but enough hardware and
* firmware bugs are still lurking out there that it's safest not to
* venture into the 64-bit space until necessary.
*
* If your device goes wrong after seeing the notice then likely either
* its driver is not setting DMA masks accurately, the hardware has
* some inherent bug in handling >32-bit addresses, or not all the
* expected address bits are wired up between the device and the IOMMU.
*/
Asking the ASM1061 on a discrete PCIe card to DMA from I/O virtual
address 0xffffffff00000000 produces the following I/O page faults:
vfio-pci 0000:07:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0021 address=0x7ff00000000 flags=0x0010]
vfio-pci 0000:07:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0021 address=0x7ff00000500 flags=0x0010]
Note that the upper 21 bits of the logged DMA address are zero. (When
asking a different PCIe device in the same PCIe slot to DMA to the
same I/O virtual address, we do see all the upper 32 bits of the DMA
address as 1, so this is not an issue with the chipset or IOMMU
configuration on the test system.)
Also, hacking libahci to always set the upper 21 bits of all DMA
addresses to 1 produces no discernible effect on the behavior of the
ASM1061, and mkfs/mount/scrub/etc work as without this hack.
This all strongly suggests that the ASM1061 has a 43 bit DMA address
limit, and this commit therefore adds a quirk to deal with this limit.
This issue probably applies to (some of) the other supported ASMedia
parts as well, but we limit it to the PCI IDs known to refer to
ASM1061 parts, as that's the only part we know for sure to be affected
by this issue at this point.
