b4b163b0e7 platform/x86: thinkpad_acpi: Ignore battery threshold change event notification
[ Upstream commit 29e4e6b423 ]

If user modifies the battery charge threshold an ACPI event is generated.
Confirmed with Lenovo FW team this is only generated on user event. As no
action is needed, ignore the event and prevent spurious kernel logs.

5277bc961c platform/x86: fujitsu-laptop: Support Lifebook S2110 hotkeys
[ Upstream commit a7e255ff9f ]

The S2110 has an additional set of media playback control keys enabled
by a hardware toggle button that switches the keys between "Application"
and "Player" modes. Toggling "Player" mode just shifts the scancode of
each hotkey up by 4.

Add defines for new scancodes, and a keymap and dmi id for the S2110.

Tested on a Fujitsu Lifebook S2110.

cb5d7e7a6f platform/x86: thinkpad_acpi: Support also NEC Lavie X1475JAS
[ Upstream commit a032f29a15 ]

Change get_thinkpad_model_data() to check for additional vendor name
"NEC" in order to support NEC Lavie X1475JAS notebook (and perhaps
more).

The reason of this works with minimal changes is because NEC Lavie
X1475JAS is a Thinkpad inside. ACPI dumps reveals its OEM ID to be
"LENOVO", BIOS version "R2PET30W" matches typical Lenovo BIOS version,
the existence of HKEY of LEN0268, with DMI fw string is "R2PHT24W".

I compiled and tested with my own machine, attached the dmesg

92f077ff52 platform/x86: think-lmi: Fix attribute name usage for non-compliant items
[ Upstream commit 8508427a6e ]

A few, quite rare, WMI attributes have names that are not compatible with
filenames, e.g. "Intel VT for Directed I/O (VT-d)".
For these cases the '/' gets replaced with '\' for display, but doesn't
get switched again when doing the WMI access.

Fix this by keeping the original attribute name and using that for sending
commands to the BIOS

48fff1267e platform/x86: asus-wmi: Fix wlan_ctrl_by_user detection
[ Upstream commit bfcfe6d335 ]

The wlan_ctrl_by_user detection was introduced by commit a50bd128f2
("asus-wmi: record wlan status while controlled by userapp").

Quoting from that commit's commit message:

"""
When you call WMIMethod(DSTS, 0x00010011) to get WLAN status, it may return

(1) 0x00050001 (On)
(2) 0x00050000 (Off)
(3) 0x00030001 (On)
(4) 0x00030000 (Off)
(5) 0x00000002 (Unknown)

(1), (2) means that the model has hardware GPIO for WLAN, you can call
WMIMethod(DEVS, 0x00010011, 1 or 0) to turn WLAN on/off.
(3), (4) means that the model doesn’t have hardware GPIO, you need to use
API or driver library to turn WLAN on/off, and call
WMIMethod(DEVS, 0x00010012, 1 or 0) to set WLAN LED status.
After you set WLAN LED status, you can see the WLAN status is changed with
WMIMethod(DSTS, 0x00010011). Because the status is recorded lastly
(ex: Windows), you can use it for synchronization.
(5) means that the model doesn’t have WLAN device.

WLAN is the ONLY special case with upper rule.
"""

The wlan_ctrl_by_user flag should be set on 0x0003000? ((3), (4) above)
return values, but the flag mistakenly also gets set on laptops with
0x0005000? ((1), (2)) return values. This is causing rfkill problems on
laptops where 0x0005000? is returned.

Fix the check to only set the wlan_ctrl_by_user flag for 0x0003000?
return values.

03e4ee3a9a platform/x86/amd/pmc: Declare quirk_spurious_8042 for MECHREVO Wujie 14XA (GX4HRXL)
[ Upstream commit 0887817e49 ]

MECHREVO Wujie 14XA (GX4HRXL) wakes up immediately after s2idle entry.
This happens regardless of whether the laptop is plugged into AC power,
or whether any peripheral is plugged into the laptop.

Similar to commit a55bdad5df ("platform/x86/amd/pmc: Disable keyboard
wakeup on AMD Framework 13"), the MECHREVO Wujie 14XA wakes up almost
instantly after s2idle suspend entry (IRQ1 is the keyboard):

2025-04-18 17:23:57,588 DEBUG:  PM: Triggering wakeup from IRQ 9
2025-04-18 17:23:57,588 DEBUG:  PM: Triggering wakeup from IRQ 1

Add this model to the spurious_8042 quirk to workaround this.

This patch does not affect the wake-up function of the built-in keyboard.
Because the firmware of this machine adds an insurance for keyboard
wake-up events, as it always triggers an additional IRQ 9 to wake up the
system.

d211757918 platform/x86/intel-uncore-freq: Fix missing uncore sysfs during CPU hotplug
commit 8d6955ed76 upstream.

In certain situations, the sysfs for uncore may not be present when all
CPUs in a package are offlined and then brought back online after boot.

This issue can occur if there is an error in adding the sysfs entry due
to a memory allocation failure. Retrying to bring the CPUs online will
not resolve the issue, as the uncore_cpu_mask is already set for the
package before the failure condition occurs.

This issue does not occur if the failure happens during module
initialization, as the module will fail to load in the event of any
error.

To address this, ensure that the uncore_cpu_mask is not set until the
successful return of uncore_freq_add_entry().

2fcb183768 platform/x86/amd: pmc: Require at least 2.5 seconds between HW sleep cycles
commit 9f5595d5f0 upstream.

When an APU exits HW sleep with no active wake sources the Linux kernel will
rapidly assert that the APU can enter back into HW sleep. This happens in a
few ms. Contrasting this to Windows, Windows can take 10s of seconds to
enter back into the resiliency phase for Modern Standby.

For some situations this can be problematic because it can cause leakage
from VDDCR_SOC to VDD_MISC and force VDD_MISC outside of the electrical
design guide specifications. On some designs this will trip the over
voltage protection feature (OVP) of the voltage regulator module, but it
could cause APU damage as well.

To prevent this risk, add an explicit sleep call so that future attempts
to enter into HW sleep will have enough time to settle. This will occur
while the screen is dark and only on cases that the APU should enter HW
sleep again, so it shouldn't be noticeable to any user.

6ea2e8743e platform/x86: msi-wmi-platform: Workaround a ACPI firmware bug
commit baf2f2c2b4 upstream.

The ACPI byte code inside the ACPI control method responsible for
handling the WMI method calls uses a global buffer for constructing
the return value, yet the ACPI control method itself is not marked
as "Serialized".
This means that calling WMI methods on this WMI device is not
thread-safe, as concurrent WMI method calls will corrupt the global
buffer.

Fix this by serializing the WMI method calls using a mutex.

The value returned by acpi_evaluate_integer() is not checked,
but the result is not always successful, so it is necessary to
add a check of the returned value.

If the result remains negative during three iterations of the loop,
then the uninitialized variable 'val' will be used in the clamp_val()
macro, so it must be initialized with the current value of the 'curr'
variable.

In this case, the algorithm should be less noisy.

[ Upstream commit d83c45aeec ]

Load the cros_ec_lpc driver based on a Framework FRMWC004 ACPI device,
which mirrors GOOG0004, but also applies npcx quirks for Framework
systems.

Matching on ACPI will let us avoid having to change the SMBIOS match
rules again and again.

e70b4b8f93 platform/x86/amd/pmf: fix cleanup in amd_pmf_init_smart_pc()
commit 5b1122fc49 upstream.

There are a few problems in this code:

First, if amd_pmf_tee_init() fails then the function returns directly
instead of cleaning up.  We cannot simply do a "goto error;" because
the amd_pmf_tee_init() cleanup calls tee_shm_free(dev->fw_shm_pool);
and amd_pmf_tee_deinit() calls it as well leading to a double free.
I have re-written this code to use an unwind ladder to free the
allocations.

Second, if amd_pmf_start_policy_engine() fails on every iteration though
the loop then the code calls amd_pmf_tee_deinit() twice which is also a
double free.  Call amd_pmf_tee_deinit() inside the loop for each failed
iteration.  Also on that path the error codes are not necessarily
negative kernel error codes.  Set the error code to -EINVAL.

There is a very subtle third bug which is that if the call to
input_register_device() in amd_pmf_register_input_device() fails then
we call input_unregister_device() on an input device that wasn't
registered.  This will lead to a reference counting underflow
because of the device_del(&dev->dev) in __input_unregister_device().
It's unlikely that anyone would ever hit this bug in real life.

1a85281415 platform/x86: ISST: Correct command storage data length
commit 9462e74c5c upstream.

After resume/online turbo limit ratio (TRL) is restored partially if
the admin explicitly changed TRL from user space.

A hash table is used to store SST mail box and MSR settings when modified
to restore those settings after resume or online. This uses a struct
isst_cmd field "data" to store these settings. This is a 64 bit field.
But isst_store_new_cmd() is only assigning as u32. This results in
truncation of 32 bits.

Change the argument to u64 from u32.

48792ab445 platform/x86: thinkpad_acpi: disable ACPI fan access for T495* and E560
commit 2b9f84e7dc upstream.

T495, T495s, and E560 laptops have the FANG+FANW ACPI methods
(therefore fang_handle and fanw_handle are not NULL) but they do not
actually work, which results in a "No such device or address" error.
The DSDT table code for the FANG+FANW methods doesn't seem to do
anything special regarding the fan being secondary. The bug was
introduced in commit 57d0557dfa ("platform/x86: thinkpad_acpi: Add
Thinkpad Edge E531 fan support"), which added a new fan control method
via the FANG+FANW ACPI methods.

Add a quirk for T495, T495s, and E560 to avoid the FANG+FANW methods.
Fan access and control is restored after forcing the legacy non-ACPI
fan control method by setting both fang_handle and fanw_handle to NULL.

77a5ed6b03 platform/x86/amd/pmf: Update PMF Driver for Compatibility with new PMF-TA
[ Upstream commit 376a8c2a14 ]

The PMF driver allocates a shared memory buffer using
tee_shm_alloc_kernel_buf() for communication with the PMF-TA.

The latest PMF-TA version introduces new structures with OEM debug
information and additional policy input conditions for evaluating the
policy binary. Consequently, the shared memory size must be increased to
ensure compatibility between the PMF driver and the updated PMF-TA.

To do so, introduce the new PMF-TA UUID and update the PMF shared memory
configuration to ensure compatibility with the latest PMF-TA version.
Additionally, export the TA UUID.

These updates will result in modifications to the prototypes of
amd_pmf_tee_init() and amd_pmf_ta_open_session().

0a30353bec platform/x86: int3472: Check for adev == NULL
[ Upstream commit cd2fd6eab4 ]

Not all devices have an ACPI companion fwnode, so adev might be NULL. This
can e.g. (theoretically) happen when a user manually binds one of
the int3472 drivers to another i2c/platform device through sysfs.

Add a check for adev not being set and return -ENODEV in that case to
avoid a possible NULL pointer deref in skl_int3472_get_acpi_buffer().

3f67e07873 platform/x86: lenovo-yoga-tab2-pro-1380-fastcharger: fix serdev race
[ Upstream commit 59616a91e5 ]

The yt2_1380_fc_serdev_probe() function calls devm_serdev_device_open()
before setting the client ops via serdev_device_set_client_ops(). This
ordering can trigger a NULL pointer dereference in the serdev controller's
receive_buf handler, as it assumes serdev->ops is valid when
SERPORT_ACTIVE is set.

This is similar to the issue fixed in commit 5e700b384e
("platform/chrome: cros_ec_uart: properly fix race condition") where
devm_serdev_device_open() was called before fully initializing the
device.

Fix the race by ensuring client ops are set before enabling the port via
devm_serdev_device_open().

Note, serdev_device_set_baudrate() and serdev_device_set_flow_control()
calls should be after the devm_serdev_device_open() call.

a8d99ce66b platform/x86: intel/pmc: Fix ioremap() of bad address
[ Upstream commit 1d7461d0c8 ]

In pmc_core_ssram_get_pmc(), the physical addresses for hidden SSRAM
devices are retrieved from the MMIO region of the primary SSRAM device.
If additional devices are not present, the address returned is zero.
Currently, the code does not check for this condition, resulting in
ioremap() incorrectly attempting to map address 0.

Add a check for a zero address and return 0 if no additional devices
are found, as it is not an error for the device to be absent.
