It is reported that on several platforms, EC firmware will not respond
non-expected QR_EC (see EC_FLAGS_QUERY_HANDSHAKE, only write QR_EC when
SCI_EVT is set).
Unfortunately, ACPI specification doesn't define when the SCI_EVT should be
cleared by the firmware, thus the original implementation queued up second
QR_EC right after writing QR_EC command and before reading the returned
event value as at that time the SCI_EVT is ensured not cleared. This
behavior is also based on the assumption that the firmware should be able
to return 0x00 to indicate "no outstanding event". This behavior did fix
issues on Samsung platforms where the spurious query value of 0x00 is
supported and didn't break platforms in my test queue.
But recently, specific Acer, Asus, Lenovo platforms keep on blaming this
change.
This patch changes the behavior to re-check the SCI_EVT a bit later and
removes EC_FLAGS_QUERY_HANDSHAKE quirks, hoping this is the Windows
compliant EC driver behavior.
In order to be robust to the possible regressions, instead of removing the
quirk directly, this patch keeps the quirk code, removes the quirk users
and keeps old behavior for Samsung platforms.

We've been suffering from the uncertainty of the SCI_EVT clearing timing.
This patch implements 3 of 4 possible modes to handle SCI_EVT clearing
variations. The old behavior is kept in this patch.
Status: QR_EC is re-checked as early as possible after checking previous
SCI_EVT. This always leads to 2 QR_EC transactions per SCI_EVT
indication and the target may implement event queue which returns
0x00 indicating "no outstanding event".
This is proven to be a conflict against Windows behavior, but is
still kept in this patch to make the EC driver robust to the
possible regressions that may occur on Samsung platforms.
Query: QR_EC is re-checked after the target has handled the QR_EC query
request command pushed by the host.
Event: QR_EC is re-checked after the target has noticed the query event
response data pulled by the host.
This timing is not determined by any IRQs, so we may need to use a
guard period in this mode, which may explain the existence of the
ec_guard() code used by the old EC driver where the re-check timing
is implemented in the similar way as this mode.
Method: QR_EC is re-checked as late as possible after completing the _Qxx
evaluation. The target may implement SCI_EVT like a level triggered
interrupt.
It is proven on kernel bugzilla 94411 that, Windows will have all
_Qxx evaluations parallelized. Thus unless required by further
evidences, we needn't implement this mode as it is a conflict of
the _Qxx parallelism requirement.
Note that, according to the reports, there are platforms that cannot be
handled using the "Status" mode without enabling the
EC_FLAGS_QUERY_HANDSHAKE quirk. But they can be handled with the other
modes according to the tests (kernel bugzilla 97381).
The following log entry can be used to confirm the differences of the 3
modes as it should appear at the different positions for the 3 modes:
Command(QR_EC) unblocked
Status: appearing after
EC_SC(W) = 0x84
Query: appearing after
EC_DATA(R) = 0xXX
where XX is the event number used to determine _QXX
Event: appearing after first
EC_SC(R) = 0xX0 SCI_EVT=x BURST=0 CMD=0 IBF=0 OBF=0
that is next to the following log entry:
Command(QR_EC) completed by hardware

During the period that a work queue is scheduled (queued up for run) but
hasn't been run, second schedule_work() could fail. This may not lead to
the loss of queries because QR_EC is always ensured to be submitted after
the work queue has been in the running state.
The event handling work queue can be changed into the loop style to allow
us to control the code in a more flexible way:
1. Makes it possible to add event=0x00 termination condition in the loop.
2. Increases the thoughput of the QR_EC transactions as the 2nd+ QR_EC
transactions may be handled in the same work item used for the 1st QR_EC
transaction, thus the delay caused by the 2nd+ work item scheduling can
be eliminated.
Except the logging message changes and the throughput improvement, this
patch is just a funcitonal no-op.

{ Update to correct 1 patch subject in the description }
We have fixed a lot of race issues in the EC driver recently.
The following commit introduces MSI udelay()/msleep() quirk to MSI laptops
to make EC firmware working for bug 12011 without root causing any EC
driver race issues:
Commit: 5423a0cb3f
Subject: ACPI: EC: Add delay for slow MSI controller
Commit: 34ff4dbccc
Subject: ACPI: EC: Separate delays for MSI hardware
The following commit extends ECDT validation quirk to MSI laptops to make
EC driver locating EC registers properly for bug 12461:
Commit: a5032bfdd9
Subject: ACPI: EC: Always parse EC device
This is a different quirk than the MSI udelay()/msleep() quirk. This patch
keeps validating ECDT for only "Micro-Star MS-171F" as reported.
The following commit extends MSI udelay()/msleep() quirk to Quanta laptops
to make EC firmware working for bug 20242, there is no requirement to
validate ECDT for Quanta laptops:
Commit: 534bc4e3d2 Mon Sep 17 00:00:00 2001
Subject: ACPI EC: enable MSI workaround for Quanta laptops
The following commit extends MSI udelay()/msleep() quirk to Clevo laptops
to make EC firmware working for bug 77431, there is no requirement to
validate ECDT for Clevo laptops:
Commit: 777cb38295
Subject: ACPI / EC: Add msi quirk for Clevo W350etq
All udelay()/msleep() quirks for MSI/Quanta/Clevo seem to be the wrong
fixes generated without fixing the EC driver race issues.
And even if it is not wrong, the guarding can be covered by the following
commits in wait polling mode:
Commit: 9e295ac14d
Subject: ACPI / EC: Reduce ec_poll() by referencing the last register access timestamp.
Commit: commit in the same series
Subject: ACPI / EC: Fix and clean up register access guarding logics.
The only case that is not covered is the inter-transaction guarding. And
there is no evidence that we need the inter-transaction guarding upon
reading the noted bug entries.
So it is time to remove the quirks and let the users to try again. If there
is a regression, the only thing we need to do is to restore the
inter-transaction guarding for the reported platforms.

We have 2 polling modes in the EC driver:
1. busy polling: originally used for the MSI quirks. udelay() is used to
perform register access guarding.
2. wait polling: normal code path uses wait_event_timeout() and it can be
woken up as soon as the transaction is completed in the interrupt mode.
It also contains the register acces guarding logic in case the interrupt
doesn't arrive and the EC driver is about to advance the transaction in
task context (the polling mode).
The wait polling is useful for interrupt mode to allow other tasks to use
the CPU during the wait.
But for the polling mode, the busy polling takes less time than the wait
polling, because if no interrupt arrives, the wait polling has to wait the
minimal HZ interval.
We have a new use case for using the busy polling mode. Some GPIO drivers
initialize PIN configuration which cause a GPIO multiplexed EC GPE to be
disabled out of the GPE register's control. Busy polling mode is useful
here as it takes less time than the wait polling. But the guarding logic
prevents it from responding even faster. We should spinning around the EC
status rather than spinning around the nop execution lasted a determined
period.
This patch introduces 2 module params for the polling mode switch and the
guard time, so that users can use the busy polling mode without the
guarding in case the guarding is not necessary. This is an example to use
the 2 module params for this purpose:
acpi.ec_busy_polling acpi.ec_polling_guard=0
We've tested the patch on a test platform. The platform suffers from such
kind of the GPIO PIN issue. The GPIO driver resets all PIN configuration
and after that, EC interrupt cannot arrive because of the multiplexing.
Then the platform suffers from a long delay carried out by the
wait_event_timeout() as all further EC transactions will run in the polling
mode. We switched the EC driver to use the busy polling mechanism instead
of the wait timeout polling mechanism and the delay is still high:
[ 44.283005] calling PNP0C0B:00+ @ 1305, parent: platform
[ 44.417548] call PNP0C0B:00+ returned 0 after 131323 usecs
And this patch can significantly reduce the delay:
[ 44.502625] calling PNP0C0B:00+ @ 1308, parent: platform
[ 44.503760] call PNP0C0B:00+ returned 0 after 1103 usecs

In the polling mode, EC driver shouldn't access the EC registers too
frequently. Though this statement is concluded from the non-root caused
bugs (see links below), we've maintained the register access guarding
logics in the current EC driver. The guarding logics can be found here and
there, makes it hard to root cause real timing issues. This patch collects
the guarding logics into one single function so that all hidden logics
related to this can be seen clearly.
The current guarding related code also has several issues:
1. Per-transaction timestamp prevents inter-transaction guarding from being
implemented in the same place. We have an inter-transaction udelay() in
acpi_ec_transaction_unblocked(), this logic can be merged into ec_poll()
if we can use per-device timestamp. This patch completes such merge to
form a new ec_guard() function and collects all guarding related hidden
logics in it.
One hidden logic is: there is no inter-transaction guarding performed
for non MSI quirk (wait polling mode), this patch skips
inter-transaction guarding before wait_event_timeout() for the wait
polling mode to reveal the hidden logic.
The other hidden logic is: there is msleep() inter-transaction guarding
performed when the GPE storming is observed. As after merging this
commit:
Commit: e1d4d90fc0
Subject: ACPI / EC: Refine command storm prevention support
EC_FLAGS_COMMAND_STORM is ensured to be cleared after invoking
acpi_ec_transaction_unlocked(), the msleep() guard logic will never
happen now. Since no one complains such change, this logic is likely
added during the old times where the EC race issues are not fixed and
the bugs are false root-caused to the timing issue. This patch simply
removes the out-dated logic. We can restore it by stop skipping
inter-transaction guarding for wait polling mode.
Two different delay values are defined for msleep() and udelay() while
they are merged in this patch to 550us.
2. time_after() causes additional delay in the polling mode (can only be
observed in noirq suspend/resume processes where polling mode is always
used) before advance_transaction() is invoked ("wait polling" log is
added before wait_event_timeout()). We can see 2 wait_event_timeout()
invocations. This is because time_after() ensures a ">" validation while
we only need a ">=" validation here:

After cleaning up all guarding logics, we have one single function
ec_guard() collecting all old, non-root-caused, hidden logics. Then we can
easily tune the logics in one place to respond to the bug reports.
Except the time_before() change, all other changes do not change the
behavior of the EC driver.

Subject: ACPI: EC: Merge IRQ and POLL modes
The irqs_disabled() check introduced in it tries to fall into busy polling
mode when the context of ec_poll() cannot sleep.
Actually ec_poll() is ensured to be invoked in the contexts that can sleep
(from a sysfs /sys/kernel/debug/ec/ec0/io access, or from
acpi_evaluate_object(), or from acpi_ec_gpe_poller()). Without the MSI
quirk, we never saw the udelay() logic invoked. Thus this check is useless

Since commit 844b03f277 we make
sure that after vblank irq off, we return the last valid
(vblank count, vblank timestamp) pair to clients, e.g., during
modesets, which is good.
An overlooked side effect of that commit for kms drivers without
support for precise vblank timestamping is that at vblank irq
enable, when we update the vblank counter from the hw counter, we
can't update the corresponding vblank timestamp, so now we have a
totally mismatched timestamp for the new count to confuse clients.
Restore old client visible behaviour from before Linux 3.17, but
zero out the timestamp at vblank counter update (instead of disable
as in original implementation) if we can't generate a meaningful
timestamp immediately for the new vblank counter. This will fix
this regression, so callers know they need to retry again later
if they need a valid timestamp, but at the same time preserves
the improvements made in the commit mentioned above.

Tegra would not only need a hardware vblank counter that
increments at leading edge of vblank, but also support
for instantaneous high precision vblank timestamp queries, ie.
a proper implementation of dev->driver->get_vblank_timestamp().
Without these, there can be off-by-one errors during vblank
disable/enable if the scanout is inside vblank at en/disable
time, and additionally clients will never see any useable
vblank timestamps when querying via drmWaitVblank ioctl. This
would negatively affect swap scheduling under X11 and Wayland.

Since acpi_reserve_resources() is defined as a device_initcall(),
there's no guarantee that it will be executed in the right order
with respect to the rest of the ACPI initialization code. On some
systems this leads to breakage if, for example, the address range
that should be reserved for the ACPI fixed registers is given to
the PCI host bridge instead if the race is won by the wrong code
path.
Fix this by turning acpi_reserve_resources() into a void function
and calling it directly from within the ACPI initialization sequence.

Currently in validate_group(), there is a static initializer
for fake_pmu.used_mask which is based on CPU_BITS_NONE but
the used_mask array size is based on CCI_PMU_MAX_HW_EVENTS.
CCI_PMU_MAX_HW_EVENTS is not based on NR_CPUS, so CPU_BITS_NONE
is not correct and will cause a build failure if NR_CPUS
is set high enough to make CPU_BITS_NONE larger than used_mask.

Pull infiniband updates from Doug Ledford:
"Minor updates for 4.1-rc
Most of the changes are fairly small and well confined. The iWARP
address reporting changes are the only ones that are a medium size. I
had these queued up prior to rc1, but due to the shuffle in
maintainers, they did not get submitted when I expected. My apologies
for that. I feel comfortable with them however due to the testing
they've received, so I left them in this submission"

Since the introduction of BIOS fb preservation, circa 3.17, we began
encountering a failure during boot when trying to use force-detect
before GEM was initialised. That bug is from

drm/i915: ensure the force pipe A quirk is actually followed
but investigation of the affected machine revealed that it was using a
PIPE-A quirk even though it was a 945GSE and the quirk is only supposed
to be used to workaround a hardware issue on 830/845. That quirk was
added for this HP Mini in
commit 6b93afc564a5e74b0eaaa46c95f557449951b3b9

add pipe a force quirk for Dell mini
in order to workaround an issue with the BIOS behaving strangely during
lid-close. Since then we have a much larger hammer to thwart the BIOS
after opening the lid and the PIPE-A quirk is no longer required.

The sink rate read from supported link rate table is in KHz as per spec
while in drm, the saved clock is in deca-KHz. So divide the link rate by
10 before storing.
Reading of rates was added by:

Way back, when the world was a simpler place and there was no war, no
evil, and no kernel bugs, there was just a single pinctrl lock. That
was how the world was when (57291ce pinctrl: core device tree mapping
table parsing support) was written. In that case, there were
instances where the pinctrl mutex was already held when
pinctrl_register_map() was called, hence a "locked" parameter was
passed to the function to indicate that the mutex was already locked
(so we shouldn't lock it again).
A few years ago in (42fed7b pinctrl: move subsystem mutex to
pinctrl_dev struct), we switched to a separate pinctrl_maps_mutex.
...but (oops) we forgot to re-think about the whole "locked" parameter
for pinctrl_register_map(). Basically the "locked" parameter appears
to still refer to whether the bigger pinctrl_dev mutex is locked, but
we're using it to skip locks of our (now separate) pinctrl_maps_mutex.
That's kind of a bad thing(TM). Probably nobody noticed because most
of the calls to pinctrl_register_map happen at boot time and we've got
synchronous device probing. ...and even cases where we're
asynchronous don't end up actually hitting the race too often. ...but
after banging my head against the wall for a bug that reproduced 1 out
of 1000 reboots and lots of looking through kgdb, I finally noticed
this.
Anyway, we can now safely remove the "locked" parameter and go back to
a war-free, evil-free, and kernel-bug-free world.

Make sure that xen_swiotlb_init allocates buffers that are DMA capable
when at least one memblock is available below 4G. Otherwise we assume
that all devices on the SoC can cope with >4G addresses. We do this on
ARM and ARM64, where dom0 is mapped 1:1, so pfn == mfn in this case.
No functional changes on x86.

At some point with all the GPIO clean-up we've broken the
MPUIO interrupts. Those are just a little bit different from
the GPIO interrupts, so we can fix it up just by setting
different irqchip functions for it. And then we can just
remove all old code trying to do the same.
