Commits 0077a504e1 ("ahci: asm1166: correct count of reported ports")
and 9815e39617 ("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 6cd8adc3e1
("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🚌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)

Turns out that due to CONFIG_DEBUG_INFO_BTF_MODULES not having an
explicitly specified "menu item name" in Kconfig, it's basically
impossible to turn it off (see [0]).
This patch fixes the issue by defining menu name for
CONFIG_DEBUG_INFO_BTF_MODULES, which makes it actually adjustable
and independent of CONFIG_DEBUG_INFO_BTF, in the sense that one can
have DEBUG_INFO_BTF=y and DEBUG_INFO_BTF_MODULES=n.
We still keep it as defaulting to Y, of course.

DRM_KMS_HELPER.
Prior to commit d674858ff9 ("drm/display: Make all helpers visible and

wasn't really a big deal. However, since that commit, it's now something
that can be enabled as is, and since there's no expressed dependency
with DRM_KMS_HELPER, it can break too.
Since DRM_KMS_HELPER is a selectable option for now, let's select it for

Different Qualcomm platforms using WCN3990 WiFI chip use SoC-specific
firmware versions with different features. For example firmware for
SDM845 doesn't use single-chan-info-per-channel feature, while firmware
for QRB2210 / QRB4210 requires that feature. Allow board DT files to
override the subdir of the fw dir used to lookup the firmware-N.bin file
decribing corresponding WiFi firmware.
For example:
- ath10k/WCN3990/hw1.0/wlanmdsp.mbn,
ath10k/WCN3990/hw1.0/firmware-5.bin: main firmware files, used by default
- ath10k/WCN3990/hw1.0/qcm2290/wlanmdsp.mbn,
ath10k/WCN3990/hw1.0/qcm2290/firmware-5.bin: SoC specific firmware
with different signature and feature bits
Note, while board files lookup uses the same function and thus it is
possible to provide board-specific board-2.bin files, this is not
required in 99% of cases as board-2.bin already contains a way to
provide board-specific data with finer granularity than DT overrides.

For some reason, we add an offset to the PDI, presumably to skip the
PDI0 and PDI1 which are reserved for BPT.
This code is however completely wrong and leads to an out-of-bounds
access. We were just lucky so far since we used only a couple of PDIs
and remained within the PDI array bounds.
A Fixes: tag is not provided since there are no known platforms where
the out-of-bounds would be accessed, and the initial code had problems
as well.
