2021-08-17platform/x86: intel_pmc_core: Prevent possibile overflowDavid E. Box
Substate priority levels are encoded in 4 bits in the LPM_PRI register. This value was used as an index to an array whose element size was less than 16, leading to the possibility of overflow should we read a larger than expected priority. In addition to the overflow, bad values could lead to incorrect state reporting. So rework the priority code to prevent the overflow and perform some validation of the register. Use the priority register values if they give an ordering of unique numbers between 0 and the maximum number of states. Otherwise, use a default ordering instead.

2021-08-13platform/x86: acer-wmi: Add Turbo Mode support for Acer PH315-53JafarAkhondali
The Acer Predator Helios series (usually denoted by PHxxx-yy) features a particular key above the keyboard named "TURBO". The turbo key does 3 things: 1. Set all fan's speeds to TURBO mode 2. Overclocks the CPU and GPU in the safe range 3. Turn on an LED just below the turbo button All the above actions are operating using WMI function calls, and there is no custom OC level for turbo. It acts as a flag for enabling turbo mode instead of telling processors to use a specific multiply of power (e.g. 1.3x of power). I've run some benchmark tests and it worked fine: GpuTest 0.7.0 http://www.geeks3d.com Module: FurMark Normal mode Score: 7289 points (FPS: 121) Turbo mode Score: 7675 points (FPS: 127) Settings: - 1920x1080 fullscreen - antialiasing: Off - duration: 60000 ms Renderer: - GeForce RTX 2060/PCIe/SSE2 - OpenGL: 4.6.0 NVIDIA 460.32.03 This feature is presented by Acer officially and should not harm hardware in any case. A challenging part of implementing this feature is that calling overclock function requires knowing the exact count of fans for CPU and GPU of each model, which to the best of my knowledge is not available in the kernel. So after checking the official PredatorSense application methods, it turned out they have provided the software the list of fans in each model. I have access to the mentioned list, and all similar PH-iii-jj can be added easily by matching "DMI_PRODUCT_NAME". Creating a specific file for the Acer gaming features is not possible because the current in use WMI event GUID is required for the turbo button and it's not possible to register multiple listeners on a single WMI event.

In Windows the ASUS Armory Crate program can enable or disable the dGPU via a WMI call. This functions much the same as various Linux methods in software where the dGPU is removed from the device tree. However the WMI call saves the state of dGPU (enabled or not) and this then changes the dGPU visibility in Linux with no way for Linux users to re-enable it.

2021-08-12platform/x86: dell-smbios: Remove unused dmi_system_id tableHans de Goede
dell-smbios is depended on by dell-laptop and that has this same table + some extra entries for chassis-type 30, 31 and 32. Since dell-laptop will already auto-load based on the DMI table in there (which also is more complete) and since dell-laptop will then bring in the dell-smbios module, the only scenario I can think of where this DMI table inside dell-smbios-smm.c is useful is if users have the dell-laptop module disabled and they want to use the sysfs interface offered by dell-smbios-smm.c. But that is such a corner case, even requiring a custom kernel build, that it does not weigh up against having this duplicate table, which as the current state already shows can only grow stale. Users who do hit this corner-case can always explicitly modprobe / insmod the module.

2021-08-12platform/x86: ISST: Fix optimization with use of numaSrinivas Pandruvada
When numa is used to map CPU to PCI device, the optimized path to read from cached data is not working and still calls _isst_if_get_pci_dev(). The reason is that when caching the mapping, numa information is not available as it is read later. So move the assignment of isst_cpu_info[cpu].numa_node before calling _isst_if_get_pci_dev().

2021-08-06platform/x86: pcengines-apuv2: Add missing terminating entries to ↵Hans de Goede
gpio-lookup tables The gpiod_lookup_table.table passed to gpiod_add_lookup_table() must be terminated with an empty entry, add this. Note we have likely been getting away with this not being present because the GPIO lookup code first matches on the dev_id, causing most lookups to skip checking the table and the lookups which do check the table will find a matching entry before reaching the end. With that said, terminating these tables properly still is obviously the correct thing to do.

2021-08-06platform/x86: Make dual_accel_detect() KIOX010A + KIOX020A detect more robustHans de Goede
360 degree hinges devices with dual KIOX010A + KIOX020A accelerometers always have both a KIOX010A and a KIOX020A ACPI device (one for each accel). Theoretical some vendor may re-use some DSDT for a non-convertible stripping out just the KIOX020A ACPI device from the DSDT. Check that both ACPI devices are present to make the check more robust.

2021-07-29platform/x86: Add and use a dual_accel_detect() helperHans de Goede
Various 360 degree hinges (yoga) style 2-in-1 devices use 2 accelerometers to allow the OS to determine the angle between the display and the base of the device. On Windows these are read by a special HingeAngleService process which calls undocumented ACPI methods, to let the firmware know if the 2-in-1 is in tablet- or laptop-mode. The firmware may use this to disable the kbd and touchpad to avoid spurious input in tablet-mode as well as to report SW_TABLET_MODE info to the OS. Since Linux does not call these undocumented methods, the SW_TABLET_MODE info reported by various pdx86 drivers is incorrect on these devices. Before this commit the intel-hid and thinkpad_acpi code already had 2 hardcoded checks for ACPI hardware-ids of dual-accel sensors to avoid reporting broken info. And now we also have a bug-report about the same problem in the intel-vbtn code. Since there are at least 3 different ACPI hardware-ids in play, add a new dual_accel_detect() helper which checks for all 3, rather then adding different hardware-ids to the drivers as bug-reports trickle in. Having shared code which checks all known hardware-ids is esp. important for the intel-hid and intel-vbtn drivers as these are generic drivers which are used on a lot of devices. The BOSC0200 hardware-id requires special handling, because often it is used for a single-accelerometer setup. Only in a few cases it refers to a dual-accel setup, in which case there will be 2 I2cSerialBus resources in the device's resource-list, so the helper checks for this.

2021-07-17platform/x86: think-lmi: Split kobject_init() and kobject_add() callsHans de Goede
tlmi_sysfs_init() calls tlmi_release_attr() on errors which calls kobject_put() for attributes created by tlmi_analyze(), but if we bail early because of an error, then this means that some of the kobjects will not have been initialized yet; and we should thus not call kobject_put() on them. Switch from using kobject_init_and_add() inside tlmi_sysfs_init() to initializing all the created kobjects directly in tlmi_analyze() and only adding them from tlmi_sysfs_init(). This way all kobjects will always be initialized when tlmi_release_attr() gets called.
