2024-11-18platform/x86: p2sb: Cache correct PCI bar for P2SB on Gemini LakeHans de Goede
Gemini Lake (Goldmont Plus) is an Apollo Lake (Goldmont) derived design and as such has the P2SB at device.function 13.0, rather then at the default 31.1, just like Apollo Lake. At a mapping to P2SB_DEVFN_GOLDMONT to p2sb_cpu_ids[] for Goldmont Plus, so that the correct PCI bar gets cached. This fixes P2SB unhiding not working on these devices, which fixes SPI support for the bootrom SPI controller not working.

2024-11-14platform/x86/intel/pmt: allow user offset for PMT callbacksMichael J. Ruhl
Usage of the telem sysfs file allows for partial reads at an offset. The current callback method returns the buffer starting from offset 0 only. Include the requested offset in the callback and update the necessary address calculations with the offset. Note: offset addition is moved from the caller to the local usage. For non-callback usage this is unchanged behavior.

To optimize performance, implement the AMD 3D V-Cache Optimizer, which allows selecting either: Frequency mode: cores within the faster CCD are prioritized before those in the slower CCD.

2024-11-12intel-hid: fix volume buttons on Thinkpad X12 Detachable Tablet Gen 1Cole Stowell
Volume buttons on Lenovo Thinkpad X12 Detachable Tablet Gen 1 did not send any input events when pressed. When loading intel-hid with the 5 Button Array explicitly enabled, the buttons functioned normally. Adds the X12 Detachable Tablet Gen 1 to the `button_array_table`. However, the driver is unable to call INTEL_HID_DSM_BTNE_FN and prints the warning "failed to set button capability" when attempting to enable or disable the 5 Button Array. The warning should be harmless and adding more special handling to avoid it is not worth it.

2024-11-12platform/x86: asus-wmi: Fix inconsistent use of thermal policiesArmin Wolf
When changing the thermal policy using the platform profile API, a Vivobook thermal policy is stored in throttle_thermal_policy_mode. However everywhere else a normal thermal policy is stored inside this variable, potentially confusing the platform profile. Fix this by always storing normal thermal policy values inside throttle_thermal_policy_mode and only do the conversion when writing the thermal policy to hardware. This also fixes the order in which throttle_thermal_policy_switch_next() steps through the thermal modes on Vivobook machines.

Add support for the Vexia EDU ATLA 10 tablet, Android 4.2/4.4 + Guadalinex Ubuntu tablet distributed to schools in the Spanish Andalucía region. Besides the usual broken DSDT issues this tablet is special because all its LPSS island peripherals are enumerated as PCI devices rather then as ACPI devices as they typically are. At the same time there are disabled (_STA=0) ACPI devices for the peripherals and child ACPI devices for e.g. attached I2C/SDIO devices are children of these disabled ACPI devices and thus will not be used by Linux since the parent is disabled. So besides the usual manual i2c-client instantiation for accel/touchscreen this tablet also requires manual i2c-client instantiation for the codec and for the PMIC. Also it seems the mainboard was designed for Windows not Android, so it has an I2C attached embedded controller instead of allowing direct access to the charger + fuel-gauge chips as is usual with Android boards. Normally when there is an embedded controller, there also is ACPI battery support, but since this shipped with Android that is missing and Linux needs to have a power_supply class driver talking directly to the EC.

2024-11-04platform/x86/amd/pmf: Switch to platform_get_resource() and ↵Shyam Sundar S K
devm_ioremap_resource() Use platform_get_resource() to fetch the memory resource instead of acpi_walk_resources() and devm_ioremap_resource() for mapping the resources. PS: We cannot use resource_size() here because it adds an extra byte to round off the size. In the case of PMF ResourceTemplate(), this rounding is already handled within the _CRS. Using resource_size() would increase the resource size by 1, causing a mismatch with the length field and leading to issues. Therefore, simply use end-start of the ACPI resource to obtain the actual length.

2024-10-30alienware-wmi: added platform profile supportKurt Borja
Implements platform profile support for Dell laptops with new WMAX thermal interface, present on some Alienware X-Series, Alienware M-Series and Dell's G-Series laptops. This interface is suspected to be used by Alienware Command Center (AWCC), which is not available for linux systems, to manage thermal profiles. This implementation makes use of three WMI methods, namely THERMAL_CONTROL, THERMAL_INFORMATION and GAME_SHIFT_STATUS, which take u32 as input and output arguments. Each method has a set of supported operations specified in their respective enums. Not all models with WMAX WMI interface support these methods. Because of this, models have to manually declare support through new quirks `thermal` for THERMAL_CONTROL and THERMAL_INFORMATION and `gmode` for GAME_SHIFT_STATUS. Wrappers written for these methods support multiple operations. THERMAL_CONTROL switches thermal modes through operation ACTIVATE_PROFILE. Available thermal codes are auto-detected at runtime and matched against a list of known thermal codes: Thermal Table "User Selectable Thermal Tables" (USTT): BALANCED 0xA0 BALANCED_PERFORMANCE 0xA1 COOL 0xA2 QUIET 0xA3 PERFORMANCE 0xA4 LOW_POWER 0xA5 Thermal Table Basic: QUIET 0x96 BALANCED 0x97 BALANCED_PERFORMANCE 0x98 PERFORMANCE 0x99 Devices are known to implement only one of these tables without mixing their thermal codes. The fact that the least significant digit of every thermal code is consecutive of one another is exploited to efficiently match codes through arrays. Autodetection of available codes is done through operation LIST_IDS of method THERMAL_INFORMATION. This operation lists fan IDs, CPU sensor ID, GPU sensor ID and available thermal profile codes, *in that order*. As number of fans and thermal codes is very model dependent, almost every ID is scanned and matched based on conditions found on is_wmax_thermal_code(). The known upper bound for the number of IDs is 13, corresponding to a device that have 4 fans, 2 sensors and 7 thermal codes. Additionally G-Series laptops have a key called G-key, which (with AWCC proprietary driver) switches the thermal mode to an special mode named GMODE with code 0xAB and changes Game Shift Status to 1. Game Shift is a mode the manufacturer claims, increases gaming performance. GAME_SHIFT_STATUS method is used to mimic this behavior when selecting PLATFORM_PROFILE_PERFORMANCE option. All of these profiles are known to only change fan speed profiles, although there are untested claims that some of them also change power profiles. Activating a thermal mode with method THERMAL_CONTROL may cause short hangs. This is a known problem present on every platform.
