The Gen11+ and the legacy function differ in the register and value
written to interrupt the GuC. However, while on older gen the value
matches a bit on the register, on Gen11+ the value is a SW defined
payload that is sent to the FW. Since the FW behaves the same no matter
what value we pass to it, we can just write the same thing on all gens
and get rid of the function pointer by saving the register offset.

Since we started using CT buffers on all gens, the function pointers can
only be set to either the _nop() or the _ct() functions. Since the
_nop() case applies to when the CT are disabled, we can just handle that
case in the _ct() functions and call them directly.

The GuC supports having multiple CT buffer pairs and we designed our
implementation with that in mind. However, the different channels are not
processed in parallel within the GuC, so there is very little advantage
in having multiple channels (independent locks?), compared to the
drawbacks (one channel can starve the other if messages keep being
submitted to it). Given this, it is unlikely we'll ever add a second
channel and therefore we can simplify our code by removing the
flexibility.

We track the status of the GuC much more closely now and we expect the
enable/disable functions to be correctly called only once. If this isn't
true we do want to flag it as a flow failure (via the BUG_ON in the ctch
functions) and not silently ignore the call.

The only difference from the GuC POV between guc_communication_stop and
guc_communication_disable is that the former can be called after GuC
has been reset. Instead of having two separate paths, we can just skip
the call into GuC in the disabling path and re-use that.
Note that by using the disable() path instead of the stop() one there
are two additional changes in SW side for the stop path:
- interrupts are now disabled before disabling the CT, which is ok
because we do not want interrupts with CT disabled;
- guc_get_mmio_msg() is called in the stop case as well, which is ok
because if there are errors before the reset we do want to record
them.

Any user of wkup_m3_ipc calls wkup_m3_ipc_get to get a handle and this
checks the value of the static variable m3_ipc_state to see if the
wkup_m3 is ready. Currently this is populated during probe before
rproc_boot has been called, meaning there is a window of time that
wkup_m3_ipc_get can return a valid handle but the wkup_m3 itself is not
ready, leading to invalid IPC calls to the wkup_m3 and system
instability.
To avoid this, move the population of the m3_ipc_state variable until
after rproc_boot has succeeded to guarantee a valid and usable handle
is always returned.

In the commit referred to below we eliminated sending of the 'gap'
indicator in regular ACK messages, reserving this to explicit NACK
ditto.
Unfortunately we missed to also eliminate building of the 'gap block'
area in ACK messages. This area is meant to report gaps in the
received packet sequence following the initial gap, so that lost
packets can be retransmitted earlier and received out-of-sequence
packets can be released earlier. However, the interpretation of those
blocks is dependent on a complete and correct sequence of gaps and
acks. Hence, when the initial gap indicator is missing a single gap
block will be interpreted as an acknowledgment of all preceding
packets. This may lead to packets being released prematurely from the
sender's transmit queue, with easily predicatble consequences.
We now fix this by not building any gap block area if there is no
initial gap to report.

This is a series I worked on with Baolin in 2017 and 2018, but we
never quite managed to finish up the last pieces. During the
ALSA developer meetup at ELC-E 2018 in Edinburgh, a decision was
made to go with this approach for keeping best compatibility
with existing source code, and then I failed to follow up by
resending the patches.
Now I have patches for all remaining time_t uses in the kernel,
so it's absolutely time to revisit them. I have done more
review of the patches myself and found a couple of minor issues
that I have fixed up, otherwise the series is still the same as
before.
Conceptually, the idea of these patches is:
- 64-bit applications should see no changes at all, neither
compile-time nor run-time.
- 32-bit code compiled with a 64-bit time_t currently
does not work with ALSA, and requires kernel changes and/or
sound/asound.h changes
- Most 32-bit code using these interfaces will work correctly
on a modified kernel, with or without the uapi header changes.
- 32-bit code using SNDRV_TIMER_IOCTL_TREAD requires the
updated header file for 64-bit time_t support
- 32-bit i386 user space with 64-bit time_t is broken for
SNDRV_PCM_IOCTL_STATUS, SNDRV_RAWMIDI_IOCTL_STATUS and
SNDRV_PCM_IOCTL_SYNC_PTR because of i386 alignment. This is also
addressed by the updated uapi header.
- PCM mmap is currently supported on native x86 kernels
(both 32-bit and 64-bit) but not for compat mode. This series breaks
the 32-bit native mmap support for 32-bit time_t, but instead allows
it for 64-bit time_t on both native and compat kernels. This seems to
be the best trade-off, as mmap support is optional already, and most
32-bit code runs in compat mode anyway.
- I've tried to avoid breaking compilation of 32-bit code
as much as possible. Anything that does break however is likely code
that is already broken on 64-bit time_t and needs source changes to
fix them.

====================
improve clause 45 support in phylink
These three patches improve the clause 45 support in phylink, fixing
some corner cases that have been noticed with the addition of SFP+
NBASE-T modules, but are actually a little more wisespread than I
initially realised.
The first issue was spotted with a NBASE-T PHY on a SFP+ module plugged
into a mvneta platform. When these PHYs are not operating in USXGMII
mode, but are in a single-lane Serdes mode, they will switch between
one of several different PHY interface modes.
If we call the MAC validate() function with the current PHY interface
mode, we will restrict the supported and advertising masks to the link
modes that the current PHY interface mode supports. For example, if we
determine that we want to start the PHY with an interface mode of
2500BASE-X, then this setup will restrict the advertisement and
supported masks to 2.5G speed link modes.
What we actually want for these PHYs is to allow them to support any
link modes that the PHY supports _and_ the MAC is also capable of
supporting. Without knowing the details of the PHY interface modes that
may be used, we can do this by using PHY_INTERFACE_MODE_NA to validate
and restrict the link modes to any that the MAC supports.
mvpp2 with the 88X3310 PHY avoids this problem, because the validate()
implementation allows all MAC supported speeds not only for
PHY_INTERFACE_MODE_NA, but also for XAUI and 10GKR modes.
The first patch addresses this; current MAC drivers should continue to
work as-is, but there will be a follow-on patch to fixup at least
mvpp2.
The second issue addresses a very similar problem that occurs when
trying to use ethtool to alter the advertisement mask - we call
the MAC validate() function with the current interface mode, the
current support and requested advertisement masks. This immediately
restricts the advertisement in the same way as the above.
This patch series addresses both issues, although the patches are not
in the above order.
v2: fix patch 3 missing 1G link modes for SGMII and RGMII interface
modes.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Fix up the mvpp2 validate implementation to adopt the same behaviour as
mvneta:
- only allow the link modes that the specified PHY interface mode
supports with the exception of 1000base-X and 2500base-X.
- use the basex helper to deal with SFP modules that can be switched
between 1000base-X vs 2500base-X.
This gives consistent behaviour between mvneta and mvpp2.

workaround" so is not marked for backporting to stable kernels.

Commit e45d1f5288 ("net: phylink: support Clause 45 PHYs on SFP+
modules") added a workaround to support clause 45 PHYs which
dynamically switch their interface mode on SFP+ modules. This was
implemented by validating the PHYs supported/advertising using
PHY_INTERFACE_MODE_NA, rather than the specific interface mode that
we attached the PHY with.
However, we already have a situation where phylink is used to connect
a Marvell 88X3310 PHY which also behaves in exactly the same way, but
which seemingly doesn't need this. The reason seems to be that the
mvpp2 driver sets a whole bunch of link modes for
PHY_INTERFACE_MODE_10GKR down to 10Mb/s, despite 10GBASE-R not actually
supporting anything but 10Gb/s speeds.
When testing with drivers that (correctly) take the mvneta approach,
where the validate() method only returns what can be supported /
advertised for the specified link mode, we find that Clause 45 PHYs do
not behave as we expect: their advertisement is restricted to what
the current link will support, rather than what the PHY supports
through its dynamic switching.
Extend this workaround to all such cases; if we have a Clause 45 PHY
attaching via any means, except in USXGMII, XAUI and RXAUI which are
all unable to support this dynamic switching or have other solutions
to it, then we need to validate using PHY_INTERFACE_MODE_NA.
This should allow mvpp2 to switch to a more conformant validate()
implementation.

While testing ethtool with the Methode DM7052 module, it was noticed
that attempting to set the advertising mask results in the mask being
truncated to the support offered by the currently chosen PHY interface
mode.
When a PHY dynamically changes the PHY interface mode, limiting the
advertising mask in this way is not correct - if the PHY happened to
negotiate 10GBASE-T, and selected 10GBASE-R as the host interface, we
don't want to restrict the advertisement to just 10GBASE-* modes.
Rework setting the advertisement to take account of this; do not pass
the requested advertisement through phylink_validate(), but rely on
the advertisement restriction (supported mask) set when the PHY was
initially setup.

The video DSI mode had not really been tested. These fixes makes

- Calculate the packet sizes in bytes as in the vendor driver,
rather than in bits. Test the calculations agains a
spreadsheet and confirmed by debug prints to be reasonable.
- Also verified the register values with relative confidence
to register dumps from the Samsung GT-I8190 boot loader
graphics. We are not identical but not off by far either.
- Error out if the current mode and refresh frequency doesn't
work out. (In the future we may simply want to scale down
the vrefresh.)
- Handle negative result in front/back/sync packages and fall
back to zero like in the vendor driver.
- Put in lots of clarifying comments and references to the
documentation where the code is hard to understand.
- Set the DSI_VID_VCA_SETTING2 field
DSI_VID_VCA_SETTING2_MAX_LINE_LIMIT to blkline_pck - 6 as in
the vendor driver and mask the field properly.
