2025-06-04platform/x86: thinkpad_acpi: Ignore battery threshold change event notificationMark Pearson1-0/+5
[ Upstream commit 29e4e6b4235fefa5930affb531fe449cac330a72 ] 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.

2025-06-04platform/x86: fujitsu-laptop: Support Lifebook S2110 hotkeysValtteri Koskivuori1-4/+29
[ Upstream commit a7e255ff9fe4d9b8b902023aaf5b7a673786bb50 ] 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.

2025-06-04platform/x86: thinkpad_acpi: Support also NEC Lavie X1475JASJohn Chau1-0/+2
[ Upstream commit a032f29a15412fab9f4352e0032836d51420a338 ] 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".

2025-06-04platform/x86: asus-wmi: Fix wlan_ctrl_by_user detectionHans de Goede1-1/+2
[ Upstream commit bfcfe6d335a967f8ea0c1980960e6f0205b5de6e ] The wlan_ctrl_by_user detection was introduced by commit a50bd128f28c ("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.

2025-05-02platform/x86: ISST: Correct command storage data lengthSrinivas Pandruvada1-1/+1
[ Upstream commit 9462e74c5c983cce34019bfb27f734552bebe59f ] 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.

2025-05-02asus-laptop: Fix an uninitialized variableDenis Arefev1-3/+6
commit 6c683c6887e4addcd6bd1ddce08cafccb0a21e32 upstream. 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. Found by Linux Verification Center (linuxtesting.org) with SVACE.

2024-12-14mfd: intel_soc_pmic_bxtwc: Use IRQ domain for TMU deviceAndy Shevchenko1-16/+6
[ Upstream commit 9b79d59e6b2b515eb9a22bc469ef7b8f0904fc73 ] While design wise the idea of converting the driver to use the hierarchy of the IRQ chips is correct, the implementation has (inherited) flaws. This was unveiled when platform_get_irq() had started WARN() on IRQ 0 that is supposed to be a Linux IRQ number (also known as vIRQ). Rework the driver to respect IRQ domain when creating each MFD device separately, as the domain is not the same for all of them.

[ Upstream commit eba9ac7abab91c8f6d351460239108bef5e7a0b6 ] Since commit fa1f68db6ca7 ("drivers: misc: pass miscdevice pointer via file private data"), the miscdevice stores a pointer to itself inside filp->private_data, which means that private_data will not be NULL when wmi_char_open() is called. This might cause memory corruption should wmi_char_open() be unable to find its driver, something which can happen when the associated WMI device is deleted in wmi_free_devices(). Fix the problem by using the miscdevice pointer to retrieve the WMI device data associated with a char device using container_of().

2023-11-08platform/x86: asus-wmi: Change ASUS_WMI_BRN_DOWN code from 0x20 to 0x2eHans de Goede1-1/+1
[ Upstream commit f37cc2fc277b371fc491890afb7d8a26e36bb3a1 ] Older Asus laptops change the backlight level themselves and then send WMI events with different codes for different backlight levels. The asus-wmi.c code maps the entire range of codes reported on brightness down keypresses to an internal ASUS_WMI_BRN_DOWN code: define NOTIFY_BRNUP_MIN 0x11 define NOTIFY_BRNUP_MAX 0x1f define NOTIFY_BRNDOWN_MIN 0x20 define NOTIFY_BRNDOWN_MAX 0x2e if (code >= NOTIFY_BRNUP_MIN && code <= NOTIFY_BRNUP_MAX) code = ASUS_WMI_BRN_UP; else if (code >= NOTIFY_BRNDOWN_MIN && code <= NOTIFY_BRNDOWN_MAX) code = ASUS_WMI_BRN_DOWN; Before this commit all the NOTIFY_BRNDOWN_MIN - NOTIFY_BRNDOWN_MAX aka 0x20 - 0x2e events were mapped to 0x20. This mapping is causing issues on new laptop models which actually send 0x2b events for printscreen presses and 0x2c events for capslock presses, which get translated into spurious brightness-down presses. The plan is disable the 0x11-0x2e special mapping on laptops where asus-wmi does not register a backlight-device to avoid the spurious brightness-down keypresses. New laptops always send 0x2e for brightness-down presses, change the special internal ASUS_WMI_BRN_DOWN value from 0x20 to 0x2e to match this in preparation for fixing the spurious brightness-down presses. This change does not have any functional impact since all of 0x20 - 0x2e is mapped to ASUS_WMI_BRN_DOWN first and only then checked against the keymap code and the new 0x2e value is still in the 0x20 - 0x2e range.

[ Upstream commit 03bea764bf61c9f9918324bda7362616024386e8 ] mlxbf-tmfifo accesses config space using native types - which works for it since the legacy virtio native types. This will break if it ever needs to support modern virtio, so with new tags previously introduced for virtio net config, sparse now warns for this in drivers. Since this is a legacy only device, fix it up using virtio_legacy_is_little_endian for now. No functional changes. Signed-off-by: Michael S.

[ Upstream commit 78034cbece79c2d730ad0770b3b7f23eedbbecf5 ] This commit fixes tmfifo console stuck issue when the virtual networking interface is in down state. In such case, the network Rx descriptors runs out and causes the Rx network packet staying in the head of the tmfifo thus blocking the console packets. The fix is to drop the Rx network packet when no more Rx descriptors. Function name mlxbf_tmfifo_release_pending_pkt() is also renamed to mlxbf_tmfifo_release_pkt() to be more approperiate.

2023-09-23platform/x86: intel: hid: Always call BTNL ACPI methodHans de Goede1-12/+9
[ Upstream commit e3ab18de2b09361d6f0e4aafb9cfd6d002ce43a1 ] On a HP Elite Dragonfly G2 the 0xcc and 0xcd events for SW_TABLET_MODE are only send after the BTNL ACPI method has been called. Likely more devices need this, so make the BTNL ACPI method unconditional instead of only doing it on devices with a 5 button array. Note this also makes the intel_button_array_enable() call in probe() unconditional, that function does its own priv->array check. This makes the intel_button_array_enable() call in probe() consistent with the calls done on suspend/resume which also rely on the priv->array check inside the function.

2023-08-11platform/x86: msi-laptop: Fix rfkill out-of-sync on MSI Wind U100Maxim Mikityanskiy1-4/+4
[ Upstream commit ad084a6d99bc182bf109c190c808e2ea073ec57b ] Only the HW rfkill state is toggled on laptops with quirks->ec_read_only (so far only MSI Wind U90/U100). There are, however, a few issues with the implementation: 1. The initial HW state is always unblocked, regardless of the actual state on boot, because msi_init_rfkill only sets the SW state, regardless of ec_read_only. 2. The initial SW state corresponds to the actual state on boot, but it can't be changed afterwards, because set_device_state returns -EOPNOTSUPP. It confuses the userspace, making Wi-Fi and/or Bluetooth unusable if it was blocked on boot, and breaking the airplane mode if the rfkill was unblocked on boot. Address the above issues by properly initializing the HW state on ec_read_only laptops and by allowing the userspace to toggle the SW state. Don't set the SW state ourselves and let the userspace fully control it. Toggling the SW state is a no-op, however, it allows the userspace to properly toggle the airplane mode. The actual SW radio disablement is handled by the corresponding rtl818x_pci and btusb drivers that have their own rfkills. Tested on MSI Wind U100 Plus, BIOS ver 1.0G, EC ver 130.

[ Upstream commit 028e6e204ace1f080cfeacd72c50397eb8ae8883 ] The while-loop may break on one of the two conditions, either ID string is empty or GUID matches. The second one, may never be reached if the parsed string is not correct GUID. In such a case the loop will never advance to check the next ID. Break possible infinite loop by factoring out guid_parse_and_compare() helper which may be moved to the generic header for everyone later on and preventing from similar mistake in the future. Interestingly that firstly it appeared when WMI was turned into a bus driver, but later when duplicated GUIDs were checked, the while-loop has been replaced by for-loop and hence no mistake made again.

2022-11-25platform/x86/intel: pmc: Don't unconditionally attach Intel PMC when virtualizedRoger Pau Monné1-0/+9
[ Upstream commit 2dbfb3f33350e1e868d3d7ed4c176d8777150878 ] The current logic in the Intel PMC driver will forcefully attach it when detecting any CPU on the intel_pmc_core_platform_ids array, even if the matching ACPI device is not present. There's no checking in pmc_core_probe() to assert that the PMC device is present, and hence on virtualized environments the PMC device probes successfully, even if the underlying registers are not present. Before commit 21ae43570940 ("platform/x86: intel_pmc_core: Substitute PCI with CPUID enumeration") the driver would check for the presence of a specific PCI device, and that prevented the driver from attaching when running virtualized. Fix by only forcefully attaching the PMC device when not running virtualized. Note that virtualized platforms can still get the device to load if the appropriate ACPI device is present on the tables provided to the VM. Make an exception for the Xen initial domain, which does have full hardware access, and hence can attach to the PMC if present.

After upgrading BIOS to U82 01.02.01 Rev.A, the console is flooded strange char "^@" which printed out every second and makes login nearly impossible. Also the below messages were shown both in console and journal/dmesg every second: usb 1-3: Device not responding to setup address. usb 1-3: device not accepting address 4, error -71 usb 1-3: device descriptor read/all, error -71 usb usb1-port3: unable to enumerate USB device Wifi is soft blocked by checking rfkill. When unblocked manually, after few seconds it would be soft blocked again. So I was suspecting something triggered rfkill to soft block wifi. At the end it was fixed by removing hp_wmi module. The root cause is the way hp-wmi driver handles command 1B on post-2009 BIOS. In pre-2009 BIOS, command 1Bh return 0x4 to indicate that BIOS no longer controls the power for the wireless devices.

2022-10-26platform/x86: msi-laptop: Change DMI match / alias strings to fix module ↵Hans de Goede1-5/+3
autoloading [ Upstream commit 2a2565272a3628e45d61625e36ef17af7af4e3de ] On a MSI S270 with Fedora 37 x86_64 / systemd-251.4 the module does not properly autoload. This is likely caused by issues with how systemd-udevd handles the single quote char (') which is part of the sys_vendor / chassis_vendor strings on this laptop. As a workaround remove the single quote char + everything behind it from the sys_vendor + chassis_vendor matches. This fixes the module not autoloading.

2022-10-26platform/x86: msi-laptop: Fix old-ec check for backlight registeringHans de Goede1-2/+1
[ Upstream commit 83ac7a1c2ed5f17caa07cbbc84bad3c05dc3bf22 ] Commit 2cc6c717799f ("msi-laptop: Port to new backlight interface selection API") replaced this check: if (!quirks->old_ec_model || acpi_video_backlight_support()) pr_info("Brightness ignored, ..."); else do_register(); With: if (quirks->old_ec_model || acpi_video_get_backlight_type() == acpi_backlight_vendor) do_register(); But since the do_register() part was part of the else branch, the entire condition should be inverted. So not only the 2 statements on either side of the || should be inverted, but the || itself should be replaced with a &&. In practice this has likely not been an issue because the new-ec models (old_ec_model==false) likely all support ACPI video backlight control, making acpi_video_get_backlight_type() return acpi_backlight_video turning the second part of the || also false when old_ec_model == false.
