3 daysplatform/x86/amd/pmf: Prevent TEE errors after hibernateShyam Sundar S K3-10/+74
[ Upstream commit 48d229c7047128dd52eaf863881bb3e62b5896e5 ] After resuming from hibernate, TEE commands can time out and cause PSP disables. Fix this by reinitializing the Trusted Application (TA) and cancelling the pb workqueue in the hibernate callbacks to avoid these errors. ccp 0000:c4:00.2: tee: command 0x5 timed out, disabling PSP amd-pmf AMDI0107:00: TEE enact cmd failed. err: ffff000e, ret:0 amd-pmf AMDI0107:00: TEE enact cmd failed. err: ffff000e, ret:0 amd-pmf AMDI0107:00: TEE enact cmd failed. err: ffff000e, ret:0 Fixes: ae82cef7d9c5 ("platform/x86/amd/pmf: Add support for PMF-TA interaction") Reported-by: Lars Francke <lars.francke@gmail.com> Closes: https://lore.kernel.org/platform-driver-x86/CAD-Ua_gfJnQSo8ucS_7ZwzuhoBRJ14zXP7s8b-zX3ZcxcyWePw@mail.gmail.com/ Tested-by: Yijun Shen <Yijun.Shen@Dell.com> Co-developed-by: Patil Rajesh Reddy <Patil.Reddy@amd.com> Signed-off-by: Patil Rajesh Reddy <Patil.Reddy@amd.com> Signed-off-by: Shyam Sundar S K <Shyam-sundar.S-k@amd.com> [ML: Add more tags] Signed-off-by: Mario Limonciello (AMD) <superm1@kernel.org> Link: https://patch.msgid.link/20260116041132.153674-2-superm1@kernel.org Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
3 daysplatform/x86: hp-wmi: fix platform profile values for Omen 16-wf1xxxKrishna Chomal1-52/+127
[ Upstream commit 8ca7515d3c76a8b629f703ff8301a75f503bcc50 ] HP Omen 16-wf1xxx (board ID 8C78) currently sends the incorrect Victus-specific thermal profile values via WMI, leading to a logical inconsistency when switching between platform profiles. The driver currently uses Victus S values: 0x00 => Balanced / Low-Power 0x01 => Performance However, Omen Gaming Hub logs / EC register inspection on Windows shows that this board is intended to use: 0x30 => Balanced / Low-Power 0x31 => Performance This patch corrects the thermal profile command values to match the values observed from Omen Gaming Hub logs. The performance benchmarks and peak power draw (from both CPU and GPU) show no observable change with this correction (suggesting that the firmware is currently tolerant of the incorrect values). However sending the correct values prevents potential regressions after future firmware updates. Refactor victus_s_thermal_profile_boards from a list of strings to a dmi_system_id table and move the lookup to module init. The new struct thermal_profile_params is used to store board-specific WMI parameters, allowing the driver to cache these values in a static pointer. This avoids repeated DMI string comparisons and allows marking of DMI table as __initconst. Testing on HP Omen 16-wf1xxx (board 8C78) confirmed WMI codes 0x30/0x31 are now sent, resolving the logical inconsistency and ensuring the value visible in EC registers match the Windows state for this profile.

3 daysplatform/x86: int0002: Remove IRQF_ONESHOT from request_irq()Sebastian Andrzej Siewior1-2/+2
[ Upstream commit f6bc712877f24dc89bdfd7bdbf1a32f3b9960b34 ] Passing IRQF_ONESHOT ensures that the interrupt source is masked until the secondary (threaded) handler is done. If only a primary handler is used then the flag makes no sense because the interrupt cannot fire (again) while its handler is running. The flag also prevents force-threading of the primary handler and the irq-core will warn about this. The flag was added to match the flag on the shared handler which uses a threaded handler and therefore IRQF_ONESHOT. This is no longer needed because devm_request_irq() now passes IRQF_COND_ONESHOT for this case. Revert adding IRQF_ONESHOT to irqflags.

2026-01-28platform/x86: classmate-laptop: Add missing NULL pointer checksRafael J. Wysocki1-0/+32
In a few places in the Classmate laptop driver, code using the accel object may run before that object's address is stored in the driver data of the input device using it. For example, cmpc_accel_sensitivity_store_v4() is the "show" method of cmpc_accel_sensitivity_attr_v4 which is added in cmpc_accel_add_v4(), before calling dev_set_drvdata() for inputdev->dev. If the sysfs attribute is accessed prematurely, the dev_get_drvdata(&inputdev->dev) call in in cmpc_accel_sensitivity_store_v4() returns NULL which leads to a NULL pointer dereference going forward. Moreover, sysfs attributes using the input device are added before initializing that device by cmpc_add_acpi_notify_device() and if one of them is accessed before running that function, a NULL pointer dereference will occur. For example, cmpc_accel_sensitivity_attr_v4 is added before calling cmpc_add_acpi_notify_device() and if it is read prematurely, the dev_get_drvdata(&acpi->dev) call in cmpc_accel_sensitivity_show_v4() returns NULL which leads to a NULL pointer dereference going forward. Fix this by adding NULL pointer checks in all of the relevant places. Signed-off-by: Rafael J.

The LTR blocking statistics and wakeup event counters are incorrectly cross-referenced during debugfs output rendering. The code populates pss_ltr_blkd[] with LTR blocking data and pss_s0ix_wakeup[] with wakeup data, but the display loops reference the wrong arrays. This causes the "LTR Blocking Status" section to print wakeup events and the "Wakes Status" section to print LTR blockers, misleading power management analysis and S0ix residency debugging.

During the rework of the fan behavior control code in commit d8e8362b09d3 ("platform/x86: acer-wmi: Fix setting of fan behavior"), acer_toggle_turbo() was changed to use WMID_gaming_set_fan_behavior() instead of WMID_gaming_set_u64() when switching the fans to turbo mode. The new function however does not check if the necessary capability (ACER_CAP_TURBO_FAN) is actually enabled on a given machine, causing the driver to potentially access unsupported features.

The tmp buffer is allocated using kcalloc() but is not freed if acpi_evaluate_dsm() fails. This causes a memory leak in the error path.

The PMT feature probe creates a child device with device_create(). If device creation fail, the code pass priv->dev (which is an ERR_PTR) to dev_err_probe(), which is not a valid device pointer. This patch change the dev_err_probe() call to use the parent auxiliary device (&auxdev->dev) and update the error message to reference the parent device name.

2025-12-29platform/x86: hp-bioscfg: Fix out-of-bounds array access in ACPI package parsingJunrui Luo5-4/+14
The hp_populate_*_elements_from_package() functions in the hp-bioscfg driver contain out-of-bounds array access vulnerabilities. These functions parse ACPI packages into internal data structures using a for loop with index variable 'elem' that iterates through enum_obj/integer_obj/order_obj/password_obj/string_obj arrays. When processing multi-element fields like PREREQUISITES and ENUM_POSSIBLE_VALUES, these functions read multiple consecutive array elements using expressions like 'enum_obj[elem + reqs]' and 'enum_obj[elem + pos_values]' within nested loops. The bug is that the bounds check only validated elem, but did not consider the additional offset when accessing elem + reqs or elem + pos_values. The fix changes the bounds check to validate the actual accessed index.

A user reported that reading the charge threshold on his device results in very strange values (like 78497792) being returned. The reason for this seems to be the fact that the driver casts the int pointer to an u8 pointer, leaving the last 3 bytes of the destination uninitialized. Fix this by using a temporary variable instead.
