597ef9ed54 [HACK] drm: Don't WARN_ON() drm_connector_set_panel_orientation() call
This method is used by OnePlus 5 (cheeseburger) during
s6e3fa5_get_modes() and calling it here (which is what all other panel
drivers seem to do as well) causes a massively long 140-line stacktrace
for the 2 hit WARN_ON()s:

af1277a488 module: demote invalid ELF header magic error message to pr_debug
This happens anytime busybox modprobe loads a compressed module and
looks especially ugly on postmarketOS for example (or basically any
initramfs); this error is rather pointless since the module is loaded
anyway afterwards.

Upstream (busybox) has no plans to do anything about this error getting
spammed:

This finally allowed me to get past the 2 ath10k_info()'s in qmi.c!

However, this doesn't fix everything; it seems you *have* to run
diag-router from https://github.com/andersson/diag to calm the firmware
down and stop constantly crashing; need to look into a way to get Wi-Fi
working later without needing this debug crap to be running.

2eea5fe9f8 power: pmi8998_fg: Rename to qcom_fg and add support for PMI8994/6
This adds support for accessing SRAM. That includes requesting and releasing
access to SRAM by setting some registers and handling the mem-avail IRQ,
configuring access, and reading from/writing to it.

Pre-gen3 fuel gauges require reading from SRAM to get voltage, current
and temperature data. Getting capacity is identical to gen3.

Tested on Xiaomi Mi Note 2 with PMI8996.

b193513789 clk: qcom: gcc-msm8998: Add LPASS adsp and core GDSCs
As a final step to entirely enable the required clock tree for the
lpass iommu and audio dsp, add the lpass core/adsp GDSCs.

As a side note, it was found out that disabling the lpass core GDSC
at any time would cause a system lockup (and reboot): disabling
this GDSC will leave the lpass iommu completely unclocked, losing
its state entirely - including the secure contexts that have been
previously set-up from the bootloader/TrustZone.
Losing this IOMMU configuration will trigger a hypervisor fault,
which will reboot the system; the only workaround for this issue
is to declare the lpass core gdsc as always-on.

It should also not be forgotten that this is all about firmware and
there may be a version of it that doesn't enable this GDSC at all
before booting Linux, which is the reason why this specific declaration
wasn't simply omitted.

a7333bdc35 input: keyboard: Add Fast GPIO-driven keyboard/keypad matrix driver
This driver is a reimplementation of matrix_keyboard, on which it
is heavily based: the former was made back in 2009 and then
lightly updated in 2012 to add some support for device-tree / OF.

It turns out that this is not enough, nor OF is fully supported,
as the global (or "clustered") interrupt is never probed, nor it
made usage of the GPIOD API which, nowadays, really simplifies
the job - but not only: it also provides means to set GPIO arrays
for controllers that are supporting this.
The latter is very important when dealing with slow GPIOs such as
I2C and/or SPI expanders (and, again, not only); by using the new
APIs everything fits the new systems, from simplifications of the
probe/remove functions to opening possibility of using expanders
to drive key matrices with or without protection diodes.

But then, why wasn't the old matrix_keyboard driver modified
instead of creating a new one?
The problem there is that the old driver is made to support the
old platform_device style and it's currently still being used by
some PXA boards that are not (yet?) ported to device-tree, so it
would be impossible to modernize it for good, which means that to
support GPIOD (which is - really - required for the aforementioned
reasons) and to fully support DT it would be necessary to wrap the
old GPIO API around the new GPIOD one, creating overhead and also
probably unnecessary memory usage, other than a very big driver
which, at least on embedded devices (having limited resources),
would be simply bad. Leaving the fact that I haven't got any old
board so it's impossible for me to analyze and optimize for them.

Since 98% of the users of the old driver are infact platforms that
have been ported to (or are born with) DT, the introduction of a
new driver that's purely made for them seemed to be the best
choice, also because the expectations are (I think) that all of
the old ARM-based boards will be ported to DT anyway, which will
actually deprecate the good old matrix_keyboard driver.

The Awinic AW9523(B) is a multi-function I2C gpio expander in a

It has two ports with 8 pins per port (for a total of 16 pins),
configurable as either PWM with 1/256 stepping or GPIO input/output,
1.8V logic input; each GPIO can be configured as input or output
independently from each other.

This IC also has an internal interrupt controller, which is capable
of generating an interrupt for each GPIO, depending on the
configuration, and will raise an interrupt on the INTN pin to
advertise this to an external interrupt controller.

fashion: some of the paths in the topology are managed through
and by, of course) the RPM uC, while some others are "AP Owned",
meaning that the AP shall do direct writes to the appropriate
QoS registers for the specific paths and ports, instead of sending
an indication to the RPM and leaving the job to that one.

9b043633d2 drm/msm/dpu: Fix timeout issues on command mode panels
In function dpu_encoder_phys_cmd_wait_for_commit_done we are always
checking if the relative CTL is started by waiting for an interrupt
to fire: it is fine to do that, but then sometimes we call this
function while the CTL is up and has never been put down, but that
interrupt gets raised only when the CTL gets a state change from
0 to 1 (disabled to enabled), so we're going to wait for something
that will never happen on its own.

Solving this while avoiding to restart the CTL is actually possible
and can be done by just checking if it is already up and running
when the wait_for_commit_done function is called: in this case, so,
if the CTL was already running, we can say that the commit is done
if the command transmission is complete (in other terms, if the
interface has been flushed).

yet accounting for speed-binning, these OPPs are referred to the
most common binning for this chip, which I have found on six phones
from Sony and one from FxTec (silver bin0, perf bin2).

At least until speed-binning gets done in the cpufreq-hw and CPR
drivers, users should enable CPR-Hardened and CPUFREQ in their own
board DT.
This is done like that because these drivers are really big, so the
idea is to keep the "base" version easier (but perfectly working),
before adding speed-binning "complications", which may... or may not
be necessary.

71dfa2b623 soc: qcom: Add support for Core Power Reduction v3, v4 and Hardened
This commit introduces a new driver, based on the one for cpr v1,
to enable support for the newer Qualcomm Core Power Reduction
hardware, known downstream as CPR3, CPR4 and CPRh, and support
for MSM8998 and SDM630 CPU power reduction.

In these new versions of the hardware, support for various new
features was introduced, including voltage reduction for the GPU,
security hardening and a new way of controlling CPU DVFS,
consisting in internal communication between microcontrollers,
specifically the CPR-Hardened and the Operating State Manager.

The CPR v3, v4 and CPRh are present in a broad range of SoCs,
from the mid-range to the high end ones including, but not limited
to, MSM8953/8996/8998, SDM630/636/660/845.

0023cba0a2 arm64: qcom: qcs404: Change CPR nvmem-names
The CPR driver's common functions were split and put in another
file in order to support newer CPR revisions: to simplify the
commonization, the expected names of the fuses had to be changed
in order for both new and old support to use the same fuse name
retrieval function and keeping the naming consistent.

The thread id was added to the fuse name and, since CPRv1 does
not support threads, it is expected to always read ID 0, which
means that the expected name here is now "cpr0_(fuse_name)"
instead of "cpr_(fuse_name)": luckily, QCS404 is the only user
so change it accordingly.

40e639041d cpufreq: qcom-hw: Implement CPRh aware OSM programming
On new SoCs (SDM845 onwards) the Operating State Manager (OSM) is
being programmed in the bootloader and write-protected by the
hypervisor, leaving to the OS read-only access to some of its
registers (in order to read the Lookup Tables and also some
status registers) and write access to the p-state register, for
for the OS to request a specific performance state to trigger a
DVFS switch on the CPU through the OSM hardware.

On old SoCs though (MSM8998, SDM630/660 and variants), the
bootloader will *not* initialize the OSM (and the CPRh, as it
is a requirement for it) before booting the OS, making any
request to trigger a performance state change ineffective, as
the hardware doesn't have any Lookup Table, nor is storing any
parameter to trigger a DVFS switch. In this case, basically all
of the OSM registers are *not* write protected for the OS, even
though some are - but write access is granted through SCM calls.

This commit introduces support for OSM programming, which has to
be done on these old SoCs that were distributed (almost?) always
with a bootloader that does not do any CPRh nor OSM init before
booting the kernel.
In order to program the OSM on these SoCs, it is necessary to
fullfill a "special" requirement: the Core Power Reduction
Hardened (CPRh) hardware block must be initialized, as the OSM
is "talking" to it in order to perform the Voltage part of DVFS;
here, we are calling initialization of this through Linux generic
power domains, specifically by requesting a genpd attach from the
qcom-cpufreq-hw driver, which will give back voltages associated
to each CPU frequency that has been declared in the OPPs, scaled
and interpolated with the previous one, and will also give us
parameters for the Array Power Mux (APM) and mem-acc, in order
for this driver to be then able to generate the Lookup Tables
that will be finally programmed to the OSM hardware.

After writing the parameters to the OSM and enabling it, all the
programming work will never happen anymore until a OS reboot, so
all of the allocations and "the rest" will be disposed-of: this
is done mainly to leave the code that was referred only to the
new SoCs intact, as to also emphasize on the fact that the OSM
HW is, in the end, the exact same; apart some register offsets
that are slightly different, the entire logic is the same.

This also adds the parameters to support CPU scaling on SDM630
and MSM8998.

Some Qualcomm SoCs' TZ/hypervisor configuration is disallowing the

For this reason, get a list of context banks that should never get

To overcome to this issue, allow specifying a different context for
bypass emulation with the optional DT property "qcom,bypass-cbndx":
if this property is not found this means that we are either booting
with ACPI instead or that we don't want to specify a custom cb because

Furthermore `last_repeat` is the field returned to the user when reading

- together with `1` - the only valid value in the upcoming Qualcomm LPG

8f8a8f3ab3 nds32: fix access_ok() checks in get/put_user
commit 8926d88ced upstream.

The get_user()/put_user() functions are meant to check for
access_ok(), while the __get_user()/__put_user() functions
don't.

This broke in 4.19 for nds32, when it gained an extraneous
check in __get_user(), but lost the check it needs in
__put_user().

b7509a4e81 m68k: fix access_ok for coldfire
commit 26509034be upstream.

While most m68k platforms use separate address spaces for user
and kernel space, at least coldfire does not, and the other
ones have a TASK_SIZE that is less than the entire 4GB address
range.

Using the default implementation of __access_ok() stops coldfire
user space from trivially accessing kernel memory.

bed07e7ecc wcn36xx: Differentiate wcn3660 from wcn3620
commit 98d504a82c upstream.

The spread of capability between the three WiFi silicon parts wcn36xx
supports is:

wcn3620 - 802.11 a/b/g
wcn3660 - 802.11 a/b/g/n
wcn3680 - 802.11 a/b/g/n/ac

We currently treat wcn3660 as wcn3620 thus limiting it to 2GHz channels.
Fix this regression by ensuring we differentiate between all three parts.

ba84f9a483 tpm: use try_get_ops() in tpm-space.c
commit fb5abce6b2 upstream.

As part of the series conversion to remove nested TPM operations:

https://lore.kernel.org/all/20190205224723.19671-1-jarkko.sakkinen@linux.intel.com/

exposure of the chip->tpm_mutex was removed from much of the upper
level code.  In this conversion, tpm2_del_space() was missed.  This
didn't matter much because it's usually called closely after a
converted operation, so there's only a very tiny race window where the
chip can be removed before the space flushing is done which causes a
NULL deref on the mutex.  However, there are reports of this window
being hit in practice, so fix this by converting tpm2_del_space() to
use tpm_try_get_ops(), which performs all the teardown checks before
acquring the mutex.

---[ end trace d4b8409def9b8b1f ]---

The reason for this warning is the attempt to get the chip->dev reference
in tpm_common_write() although the reference counter is already zero.

Since commit 8979b02aaf ("tpm: Fix reference count to main device") the
extra reference used to prevent a premature zero counter is never taken,
because the required TPM_CHIP_FLAG_TPM2 flag is never set.

Fix this by moving the TPM 2 character device handling from
tpm_chip_alloc() to tpm_add_char_device() which is called at a later point
in time when the flag has been set in case of TPM2.

Commit fdc915f7f7 ("tpm: expose spaces via a device link /dev/tpmrm<n>")
already introduced function tpm_devs_release() to release the extra
reference but did not implement the required put on chip->devs that results
in the call of this function.

Fix this by putting chip->devs in tpm_chip_unregister().

Finally move the new implementation for the TPM 2 handling into a new
function to avoid multiple checks for the TPM_CHIP_FLAG_TPM2 flag in the
good case and error cases.

46bb87d406 mac80211: fix potential double free on mesh join
commit 4a2d4496e1 upstream.

While commit 6a01afcf84 ("mac80211: mesh: Free ie data when leaving
mesh") fixed a memory leak on mesh leave / teardown it introduced a
potential memory corruption caused by a double free when rejoining the
mesh:

  ieee80211_leave_mesh()
  -> kfree(sdata->u.mesh.ie);
  ...
  ieee80211_join_mesh()
  -> copy_mesh_setup()
     -> old_ie = ifmsh->ie;
     -> kfree(old_ie);

This double free / kernel panics can be reproduced by using wpa_supplicant
with an encrypted mesh (if set up without encryption via "iw" then
ifmsh->ie is always NULL, which avoids this issue). And then calling:

  $ iw dev mesh0 mesh leave
  $ iw dev mesh0 mesh join my-mesh

Note that typically these commands are not used / working when using
wpa_supplicant. And it seems that wpa_supplicant or wpa_cli are going
through a NETDEV_DOWN/NETDEV_UP cycle between a mesh leave and mesh join
where the NETDEV_UP resets the mesh.ie to NULL via a memcpy of
default_mesh_setup in cfg80211_netdev_notifier_call, which then avoids
the memory corruption, too.

The issue was first observed in an application which was not using
wpa_supplicant but "Senf" instead, which implements its own calls to
nl80211.

Fixing the issue by removing the kfree()'ing of the mesh IE in the mesh
join function and leaving it solely up to the mesh leave to free the
mesh IE.

cfda62aaf8 rcu: Don't deboost before reporting expedited quiescent state
commit 10c5357874 upstream.

Currently rcu_preempt_deferred_qs_irqrestore() releases rnp->boost_mtx
before reporting the expedited quiescent state.  Under heavy real-time
load, this can result in this function being preempted before the
quiescent state is reported, which can in turn prevent the expedited grace
period from completing.  Tim Murray reports that the resulting expedited
grace periods can take hundreds of milliseconds and even more than one
second, when they should normally complete in less than a millisecond.

This was fine given that there were no particular response-time
constraints for synchronize_rcu_expedited(), as it was designed
for throughput rather than latency.  However, some users now need
sub-100-millisecond response-time constratints.

This patch therefore follows Neeraj's suggestion (seconded by Tim and
by Uladzislau Rezki) of simply reversing the two operations.

there is a commit in progress, then this transaction might get committed
and freed via jbd2_journal_commit_transaction() ->
jbd2_journal_free_transaction(), when we release j_state_lock.

acquire j_state_lock to avoid use-after-free issue.

5f32afca84 Bluetooth: btusb: Use quirk to skip HCI_FLT_CLEAR_ALL on fake CSR controllers
commit b3cf94c8b6 upstream.

Another subset of the more recent batch of Chinese clones aren't
specs-compliant and seem to lock up whenever they receive a
HCI_OP_SET_EVENT_FLT with flt_type set to zero/HCI_FLT_CLEAR_ALL,
which on Linux (until the recent HCI state-machine refactor) happened
right at BR/EDR setup. As there are other less-straightforward ways
of reaching those operations, this patch is still relevant.

So, while all the previous efforts to wrangle the herd of fake CSRs
seem to be paying off (and these also get detected as such) we
still need to take care of this quirk; testers seem to agree
that these dongles tend to work well enough afterwards.

From some cursory USB packet capture on Windows it seems like
that driver doesn't appear to use this clear-all functionality at all.

This patch was tested on some really popular AliExpress-style
dongles, in my case marked as "V5.0". Chip markings: UG8413,
the backside of the PCB says "USB Dangel" (sic).

Here is the `hciconfig -a` output; for completeness:

Also, changed the benign dmesg print that shows up whenever the

it's okay and done on a best-effort basis, not a problem
if that does not work.

Also, swapped the HCI subver and LMP subver numbers for the Barrot

608d06085d crypto: qat - disable registration of algorithms
commit 8893d27ffc upstream.

The implementations of aead and skcipher in the QAT driver do not
support properly requests with the CRYPTO_TFM_REQ_MAY_BACKLOG flag set.
If the HW queue is full, the driver returns -EBUSY but does not enqueue
the request.
This can result in applications like dm-crypt waiting indefinitely for a
completion of a request that was never submitted to the hardware.

To avoid this problem, disable the registration of all crypto algorithms
in the QAT driver by setting the number of crypto instances to 0 at
configuration time.

0d73a21c48 ACPI: video: Force backlight native for Clevo NL5xRU and NL5xNU
commit c844d22fe0 upstream.

Clevo NL5xRU and NL5xNU/TUXEDO Aura 15 Gen1 and Gen2 have both a working
native and video interface. However the default detection mechanism first
registers the video interface before unregistering it again and switching
to the native interface during boot. This results in a dangling SBIOS
request for backlight change for some reason, causing the backlight to
switch to ~2% once per boot on the first power cord connect or disconnect
event. Setting the native interface explicitly circumvents this buggy
behaviour by avoiding the unregistering process.

9024419ced ACPI: battery: Add device HID and quirk for Microsoft Surface Go 3
commit 7dacee0b9e upstream.

For some reason, the Microsoft Surface Go 3 uses the standard ACPI
interface for battery information, but does not use the standard PNP0C0A
HID. Instead it uses MSHW0146 as identifier. Add that ID to the driver
as this seems to work well.

Additionally, the power state is not updated immediately after the AC
has been (un-)plugged, so add the respective quirk for that.

4006144228 ACPI / x86: Work around broken XSDT on Advantech DAC-BJ01 board
commit e702196bf8 upstream.

On this board the ACPI RSDP structure points to both a RSDT and an XSDT,
but the XSDT points to a truncated FADT. This causes all sorts of trouble
and usually a complete failure to boot after the following error occurs:

  ACPI Error: Unsupported address space: 0x20 (*/hwregs-*)
  ACPI Error: AE_SUPPORT, Unable to initialize fixed events (*/evevent-*)
  ACPI: Unable to start ACPI Interpreter

This leaves the ACPI implementation in such a broken state that subsequent
kernel subsystem initialisations go wrong, resulting in among others
mismapped PCI memory, SATA and USB enumeration failures, and freezes.

As this is an older embedded platform that will likely never see any BIOS
updates to address this issue and its default shipping OS only complies to
ACPI 1.0, work around this by forcing `acpi=rsdt`. This patch, applied on
top of Linux 5.10.102, was confirmed on real hardware to fix the issue.

7a378016d6 ALSA: pci: fix reading of swapped values from pcmreg in AC97 codec
commit 17aaf01933 upstream.

Tests 72 and 78 for ALSA in kselftest fail due to reading
inconsistent values from some devices on a VirtualBox
Virtual Machine using the snd_intel8x0 driver for the AC'97
Audio Controller device.
Taking for example test number 72, this is what the test reports:
"Surround Playback Volume.0 expected 1 but read 0, is_volatile 0"
"Surround Playback Volume.1 expected 0 but read 1, is_volatile 0"
These errors repeat for each value from 0 to 31.

Taking a look at these error messages it is possible to notice
that the written values are read back swapped.
When the write is performed, these values are initially stored in
an array used to sanity-check them and write them in the pcmreg
array. To write them, the two one-byte values are packed together
in a two-byte variable through bitwise operations: the first
value is shifted left by one byte and the second value is stored in the
right byte through a bitwise OR. When reading the values back,
right shifts are performed to retrieve the previously stored
bytes. These shifts are executed in the wrong order, thus
reporting the values swapped as shown above.

This patch fixes this mistake by reversing the read
operations' order.

e9d0553225 ALSA: pcm: Fix races among concurrent prepare and hw_params/hw_free calls
commit 3c3201f8c7 upstream.

Like the previous fixes to hw_params and hw_free ioctl races, we need
to paper over the concurrent prepare ioctl calls against hw_params and
hw_free, too.

This patch implements the locking with the existing
runtime->buffer_mutex for prepare ioctls.  Unlike the previous case
for snd_pcm_hw_hw_params() and snd_pcm_hw_free(), snd_pcm_prepare() is
performed to the linked streams, hence the lock can't be applied
simply on the top.  For tracking the lock in each linked substream, we
modify snd_pcm_action_group() slightly and apply the buffer_mutex for
the case stream_lock=false (formerly there was no lock applied)
there.

dd2f8c684d ALSA: pcm: Fix races among concurrent read/write and buffer changes
commit dca947d4d2 upstream.

In the current PCM design, the read/write syscalls (as well as the
equivalent ioctls) are allowed before the PCM stream is running, that
is, at PCM PREPARED state.  Meanwhile, we also allow to re-issue
hw_params and hw_free ioctl calls at the PREPARED state that may
change or free the buffers, too.  The problem is that there is no
protection against those mix-ups.

This patch applies the previously introduced runtime->buffer_mutex to
the read/write operations so that the concurrent hw_params or hw_free
call can no longer interfere during the operation.  The mutex is
unlocked before scheduling, so we don't take it too long.

1bbf82d9f9 ALSA: pcm: Fix races among concurrent hw_params and hw_free calls
commit 92ee3c60ec upstream.

Currently we have neither proper check nor protection against the
concurrent calls of PCM hw_params and hw_free ioctls, which may result
in a UAF.  Since the existing PCM stream lock can't be used for
protecting the whole ioctl operations, we need a new mutex to protect
those racy calls.

This patch introduced a new mutex, runtime->buffer_mutex, and applies
it to both hw_params and hw_free ioctl code paths.  Along with it, the
both functions are slightly modified (the mmap_count check is moved
into the state-check block) for code simplicity.

e74a069c6a ALSA: oss: Fix PCM OSS buffer allocation overflow
commit efb6402c3c upstream.

We've got syzbot reports hitting INT_MAX overflow at vmalloc()
allocation that is called from snd_pcm_plug_alloc().  Although we
apply the restrictions to input parameters, it's based only on the
hw_params of the underlying PCM device.  Since the PCM OSS layer
allocates a temporary buffer for the data conversion, the size may
become unexpectedly large when more channels or higher rates is given;
in the reported case, it went over INT_MAX, hence it hits WARN_ON().

This patch is an attempt to avoid such an overflow and an allocation
for too large buffers.  First off, it adds the limit of 1MB as the
upper bound for period bytes.  This must be large enough for all use
cases, and we really don't want to handle a larger temporary buffer
than this size.  The size check is performed at two places, where the
original period bytes is calculated and where the plugin buffer size
is calculated.

In addition, the driver uses array_size() and array3_size() for
multiplications to catch overflows for the converted period size and
buffer bytes.

This is essentially a revert of the commit dc865fb9e7 ("ASoC: sti:

snd_pcm_stop() calls with snd_pcm_stop_xrun().

The commit above introduced a deadlock as snd_pcm_stop_xrun() itself
takes the PCM stream lock while the caller already holds it.  Since
the conversion was done only for consistency reason and the open-call
with snd_pcm_stop() to the XRUN state is a correct usage, let's revert
the commit back as the fix.

or risk the infamous message from unregister_netdevice()
at device dismantle.

0d15c66771 tpm: Fix error handling in async work
commit 2e8e4c8f66 upstream.

When an invalid (non existing) handle is used in a TPM command,
that uses the resource manager interface (/dev/tpmrm0) the resource
manager tries to load it from its internal cache, but fails and
the tpm_dev_transmit returns an -EINVAL error to the caller.
The existing async handler doesn't handle these error cases
currently and the condition in the poll handler never returns
mask with EPOLLIN set.
The result is that the poll call blocks and the application gets stuck
until the user_read_timer wakes it up after 120 sec.
Change the tpm_dev_async_work function to handle error conditions
returned from tpm_dev_transmit they are also reflected in the poll mask
and a correct error code could passed back to the caller.

What: /sys/devices/system/machinecheck/machinecheckX/tolerant
Contact: Borislav Petkov <bp@suse.de>
Date: Dec, 2021
Description:
Unused and obsolete after the advent of recoverable machine
checks (see last sentence below) and those are present since
2010 (Nehalem).
Original description:
The entries appear for each CPU, but they are truly shared
between all CPUs.
Tolerance level. When a machine check exception occurs for a
non corrected machine check the kernel can take different
actions.
Since machine check exceptions can happen any time it is
sometimes risky for the kernel to kill a process because it
defies normal kernel locking rules. The tolerance level
configures how hard the kernel tries to recover even at some
risk of deadlock. Higher tolerant values trade potentially
better uptime with the risk of a crash or even corruption
(for tolerant >= 3).
== ===========================================================
0 always panic on uncorrected errors, log corrected errors
1 panic or SIGBUS on uncorrected errors, log corrected errors
2 SIGBUS or log uncorrected errors, log corrected errors
3 never panic or SIGBUS, log all errors (for testing only)
== ===========================================================
Default: 1
Note this only makes a difference if the CPU allows recovery
from a machine check exception. Current x86 CPUs generally
do not.

For example, if a device supports AES-256-XTS inline encryption

Description:
This sysfs interface allows user to configure features at
runtime. The user can enable or disable features running at
firmware as well as the user can configure the parameters of
the features at runtime. The supported features are over
temperature and external watchdog. Here, the external watchdog
is completely different than the /dev/watchdog as the external
watchdog is running on the firmware and it is used to monitor
the health of firmware not APU(Linux). Also, the external
watchdog is interfaced outside of the zynqmp soc.
The supported config ids are for the feature configuration is,
1. PM_FEATURE_OVERTEMP_STATUS = 1, the user can enable or
disable the over temperature feature.
2. PM_FEATURE_OVERTEMP_VALUE = 2, the user can configure the
over temperature limit in Degree Celsius.
3. PM_FEATURE_EXTWDT_STATUS = 3, the user can enable or disable
the external watchdog feature.
4. PM_FEATURE_EXTWDT_VALUE = 4, the user can configure the
external watchdog feature.
Usage:
Select over temperature config ID to enable/disable feature
# echo 1 > /sys/devices/platform/firmware\:zynqmp-firmware/feature_config_id
Check over temperature config ID is selected or not
# cat /sys/devices/platform/firmware\:zynqmp-firmware/feature_config_id

Description:
Some ECs have a feature where they will track transitions of
a hardware-controlled sleep line, such as Intel's SLP_S0 line,
in order to detect cases where a system failed to go into deep
sleep states. The suspend_timeout_ms file controls the amount of
time in milliseconds the EC will wait before declaring a sleep
timeout event and attempting to wake the system.
Supply 0 to use the default value coded into EC firmware. Supply
65535 (EC_HOST_SLEEP_TIMEOUT_INFINITE) to disable the EC sleep
failure detection mechanism. Values in between 0 and 65535
indicate the number of milliseconds the EC should wait after a
sleep transition before declaring a timeout. This includes both
the duration after a sleep command was received but before the
hardware line changed, as well as the duration between when the
hardware line changed and the kernel sent an EC resume command.

What: security/secrets/coco
Date: February 2022
Contact: Dov Murik <dovmurik@linux.ibm.com>
Description:
Exposes confidential computing (coco) EFI secrets to
userspace via securityfs.
EFI can declare memory area used by confidential computing
platforms (such as AMD SEV and SEV-ES) for secret injection by
the Guest Owner during VM's launch. The secrets are encrypted
by the Guest Owner and decrypted inside the trusted enclave,
and therefore are not readable by the untrusted host.
The efi_secret module exposes the secrets to userspace. Each
secret appears as a file under <securityfs>/secrets/coco,
where the filename is the GUID of the entry in the secrets
table. This module is loaded automatically by the EFI driver
if the EFI secret area is populated.
Two operations are supported for the files: read and unlink.
Reading the file returns the content of secret entry.
Unlinking the file overwrites the secret data with zeroes and
removes the entry from the filesystem. A secret cannot be read
after it has been unlinked.
For example, listing the available secrets::
# modprobe efi_secret
# ls -l /sys/kernel/security/secrets/coco
-r--r----- 1 root root 0 Jun 28 11:54 736870e5-84f0-4973-92ec-06879ce3da0b

-r--r----- 1 root root 0 Jun 28 11:54 e6f5a162-d67f-4750-a67c-5d065f2a9910

# cat /sys/kernel/security/secrets/coco/e6f5a162-d67f-4750-a67c-5d065f2a9910
the-content-of-the-secret-data
Wiping a secret by unlinking a file::
# rm /sys/kernel/security/secrets/coco/e6f5a162-d67f-4750-a67c-5d065f2a9910
# ls -l /sys/kernel/security/secrets/coco

Description:
(RW) When a CXL decoder is of devtype "cxl_decoder_endpoint" it
translates from a host physical address range, to a device local
address range. Device-local address ranges are further split
into a 'ram' (volatile memory) range and 'pmem' (persistent
memory) range. The 'mode' attribute emits one of 'ram', 'pmem',
'mixed', or 'none'. The 'mixed' indication is for error cases
when a decoder straddles the volatile/persistent partition
boundary, and 'none' indicates the decoder is not actively
decoding, or no DPA allocation policy has been set.
'mode' can be written, when the decoder is in the 'disabled'
state, with either 'ram' or 'pmem' to set the boundaries for the
next allocation.

Description:
(RW) When a CXL decoder is of devtype "cxl_decoder_endpoint" it
translates from a host physical address range, to a device local
address range. The range, base address plus length in bytes, of
DPA allocated to this decoder is conveyed in these 2 attributes.
Allocations can be mutated as long as the decoder is in the
disabled state. A write to 'dpa_size' releases the previous DPA
allocation and then attempts to allocate from the free capacity
in the device partition referred to by 'decoderX.Y/mode'.
Allocate and free requests can only be performed on the highest
instance number disabled decoder with non-zero size. I.e.
allocations are enforced to occur in increasing 'decoderX.Y/id'
order and frees are enforced to occur in decreasing
'decoderX.Y/id' order.

The sensor rotates measurement across 4 phases
(PH0, PH1, PH2, PH3), where the inputs are configured
and then measured.
By default, during the first phase, [PH0], CS0 is measured,
while CS1 and CS2 are used as shields.
`cat in_proximity0_setup` returns "MI,DS,DS".
[PH1], CS1 is measured, CS0 and CS2 are shield:
`cat in_proximity1_setup` returns "DS,MI,DS".
[PH2], CS2 is measured, CS0 and CS1 are shield:
`cat in_proximity1_setup` returns "DS,DS,MI".
[PH3], CS1 and CS2 are measured (combo mode):
`cat in_proximity1_setup` returns "DS,MI,MI".
Note, these are the chip default. Hardware layout will most
likely dictate different output. The entry is read-only.

Contact: Alex Williamson <alex.williamson@redhat.com>
Description:
These files provide an interface to PCIe Resizable BAR support.
A file is created for each BAR resource (N) supported by the
PCIe Resizable BAR extended capability of the device. Reading
each file exposes the bitmap of available resource sizes:
# cat resource1_resize
00000000000001c0
The bitmap represents supported resource sizes for the BAR,
where bit0 = 1MB, bit1 = 2MB, bit2 = 4MB, etc. In the above
example the device supports 64MB, 128MB, and 256MB BAR sizes.
When writing the file, the user provides the bit position of
the desired resource size, for example:
# echo 7 > resource1_resize
This indicates to set the size value corresponding to bit 7,
128MB. The resulting size is 2 ^ (bit# + 20). This definition
matches the PCIe specification of this capability.
In order to make use of resource resizing, all PCI drivers must
be unbound from the device and peer devices under the same
parent bridge may need to be soft removed. In the case of
VGA devices, writing a resize value will remove low level
console drivers from the device. Raw users of pci-sysfs
resourceN attributes must be terminated prior to resizing.
Success of the resizing operation is not guaranteed.

Description:
The entries appear for each CPU, but they are truly shared

Tolerance level. When a machine check exception occurs for a
non corrected machine check the kernel can take different
actions.
Since machine check exceptions can happen any time it is
sometimes risky for the kernel to kill a process because it
defies normal kernel locking rules. The tolerance level
configures how hard the kernel tries to recover even at some
risk of deadlock. Higher tolerant values trade potentially
better uptime with the risk of a crash or even corruption
(for tolerant >= 3).
== ===========================================================
0 always panic on uncorrected errors, log corrected errors
1 panic or SIGBUS on uncorrected errors, log corrected errors
2 SIGBUS or log uncorrected errors, log corrected errors
3 never panic or SIGBUS, log all errors (for testing only)
== ===========================================================
