2024-08-26platform/x86: x86-android-tablets: Make Lenovo Yoga Tab 3 X90F DMI match ↵Hans de Goede
less strict There are 2G and 4G RAM versions of the Lenovo Yoga Tab 3 X90F and it turns out that the 2G version has a DMI product name of "CHERRYVIEW D1 PLATFORM" where as the 4G version has "CHERRYVIEW C0 PLATFORM". The sys-vendor + product-version check are unique enough that the product-name check is not necessary. Drop the product-name check so that the existing DMI match for the 4G RAM version also matches the 2G RAM version.

2024-08-26platform/x86: asus-wmi: Fix spurious rfkill on UX8406MAMathieu Fenniak
The Asus Zenbook Duo (UX8406MA) has a keyboard which can be placed on the laptop to connect it via USB, or can be removed from the laptop to reveal a hidden secondary display in which case the keyboard operates via Bluetooth. When it is placed on the secondary display to connect via USB, it emits a keypress for a wireless disable. This causes the rfkill system to be activated disconnecting the current wifi connection, which doesn't reflect the user's true intention. Detect this hardware and suppress any wireless switches from the keyboard; this keyboard does not have a wireless toggle capability so these presses are always spurious.

2024-08-23platform/x86/amd/pmc: Fix SMU command submission path on new AMD platformShyam Sundar S K
The commit 426463d94d45 ("platform/x86/amd/pmc: Send OS_HINT command for new AMD platform") was introduced to enable sending mailbox commands to PMFW on newer platforms. However, it was later discovered that the commit did not configure the correct message port ID (i.e., S2D or PMC). Without this configuration, all command submissions to PMFW are treated as invalid, leading to command failures. To address this issue, the CPU ID association for the new platform needs to be added in amd_pmc_get_ip_info(). This ensures that the correct SMU port IDs are selected.

2024-08-22platform/x86: acerhdf: Use the .should_bind() thermal zone callbackRafael J. Wysocki
Make the acerhdf driver use the .should_bind() thermal zone callback to provide the thermal core with the information on whether or not to bind the given cooling device to the given trip point in the given thermal zone. If it returns 'true', the thermal core will bind the cooling device to the trip and the corresponding unbinding will be taken care of automatically by the core on the removal of the involved thermal zone or cooling device. The previously existing acerhdf_bind() function bound cooling devices to thermal trip point 0 only, so the new callback needs to return 'true' for trip point 0. However, it is straightforward to observe that trip point 0 is an active trip point and the only other trip point in the driver's thermal zone is a critical one, so it is sufficient to return 'true' from that callback if the type of the given trip point is THERMAL_TRIP_ACTIVE.

When only the last resource is invalid, tpmi_sst_dev_add() is returing error even if there are other valid resources before. This function should return error when there are no valid resources. Here tpmi_sst_dev_add() is returning "ret" variable. But this "ret" variable contains the failure status of last call to sst_main(), which failed for the invalid resource. But there may be other valid resources before the last entry. To address this, do not update "ret" variable for sst_main() return status. If there are no valid resources, it is already checked for by !inst below the loop and -ENODEV is returned.

In DSDT this uart port will be defined as: Name (_HID, "DELL0501") Name (_CID, EisaId ("PNP0501") Now the first AIO has turned up which has not only the DSDT bits for this, but also an actual controller attached to the UART, yet it is not using this controller for backlight control. Use the acpi_video_get_backlight_type() function from the ACPI video-detect code to check if the dell-uart-backlight driver should actually be used. This allows reusing the existing ACPI video-detect infra to override the backlight control method on the commandline or with DMI quirks.

2024-08-19platform/x86: serial-multi-instantiate: Don't require both I2C and SPIRichard Fitzgerald
Change the Kconfig dependency so that it doesn't require both I2C and SPI subsystems to be built. Make a few small changes to the code so that the code for a bus is only called if the bus is being built. When SPI support was added to serial-multi-instantiate it created a dependency that both CONFIG_I2C and CONFIG_SPI must be enabled. Typically they are, but there's no reason why this should be a requirement. A specific kernel build could have only I2C devices or only SPI devices. It should be possible to use serial-multi-instantiate if only I2C or only SPI is enabled. The dependency formula used is: depends on (I2C && !SPI) || (!I2C && SPI) || (I2C && SPI) The advantage of this approach is that if I2C=m or SPI=m then SERIAL_MULTI_INSTANTIATE is limited to n/m.

2024-08-19platform/x86: lg-laptop: Add operation region supportArmin Wolf
The LEGX0820 ACPI device is expected to provide a custom operation region: OperationRegion (XIN1, 0x8F, Zero, 0x04B0) Field (XIN1, AnyAcc, Lock, Preserve) { DMSG, 8, HDAP, 8, Offset (0x03), AFNM, 8, Offset (0x10), P80B, 8, P81B, 8, P82B, 8, P83B, 8, P84B, 8, P85B, 8, P86B, 8, P87B, 8, Offset (0x20), DTTM, 8, TMP1, 8, LTP1, 8, HTP1, 8, TMP2, 8, LTP2, 8, HTP2, 8, Offset (0x3E8), PMSG, 1600 } The PMSG field is used by AML code to log debug messages when DMSG is true. Since those debug messages are already logged using the standard ACPI Debug object, we set DMSG unconditionally to 0x00 and ignore any writes to PMSG. The TMPx, LTPx, HTPx and AFNM fields are used to inform the driver when the temperature/(presumably) trip points/fan mode changes. This only happens when the DTTM flag is set. Unfortunately we have to implement support for this operation region because the AML codes uses code constructs like this one: If (((\_SB.XINI.PLAV != Zero) && (\_SB.XINI.DTTM != Zero))) The PLAV field gets set to 1 when the driver registers its address space handler, so by default XIN1 should not be accessed. However ACPI does not use short-circuit evaluation when evaluating logical conditions. This causes the DTTM field to be accessed even when PLAV is 0, which results in an ACPI error. Since this check happens inside various thermal-related ACPI control methods, various thermal zone become unusable since any attempt to read their temperature results in an ACPI error. Fix this by providing support for this operation region. I suspect that the problem does not happen under Windows (which seemingly does not use short-circuit evaluation either) because the necessary driver comes preinstalled with the machine.

2024-08-13platform/surface: aggregator: Fix warning when controller is destroyed in probeMaximilian Luz
There is a small window in ssam_serial_hub_probe() where the controller is initialized but has not been started yet. Specifically, between ssam_controller_init() and ssam_controller_start(). Any failure in this window, for example caused by a failure of serdev_device_open(), currently results in an incorrect warning being emitted. In particular, any failure in this window results in the controller being destroyed via ssam_controller_destroy(). This function checks the state of the controller and, in an attempt to validate that the controller has been cleanly shut down before we try and deallocate any resources, emits a warning if that state is not SSAM_CONTROLLER_STOPPED. However, since we have only just initialized the controller and have not yet started it, its state is SSAM_CONTROLLER_INITIALIZED. Note that this is the only point at which the controller has this state, as it will change after we start the controller with ssam_controller_start() and never revert back. Further, at this point no communication has taken place and the sender and receiver threads have not been started yet (and we may not even have an open serdev device either). Therefore, it is perfectly safe to call ssam_controller_destroy() with a state of SSAM_CONTROLLER_INITIALIZED. This, however, means that the warning currently being emitted is incorrect. Fix it by extending the check.

2024-08-12platform/x86/intel/ifs: Add SBAF test supportJithu Joseph
In a core, the SBAF test engine is shared between sibling CPUs. An SBAF test image contains multiple bundles. Each bundle is further composed of subunits called programs. When a SBAF test (for a particular core) is triggered by the user, each SBAF bundle from the loaded test image is executed sequentially on all the threads on the core using the stop_core_cpuslocked mechanism. Each bundle execution is initiated by writing to MSR_ACTIVATE_SBAF. SBAF test bundle execution may be aborted when an interrupt occurs or if the CPU does not have enough power budget for the test. In these cases the kernel restarts the test from the aborted bundle. SBAF execution is not retried if the test fails or if the test makes no forward progress after 5 retries.

2024-08-12platform/x86/intel/ifs: Add SBAF test image loading supportJithu Joseph
Structural Based Functional Test at Field (SBAF) is a new type of testing that provides comprehensive core test coverage complementing existing IFS tests like Scan at Field (SAF) or ArrayBist. SBAF device will appear as a new device instance (intel_ifs_2) under /sys/devices/virtual/misc. The user interaction necessary to load the test image and test a particular core is the same as the existing scan test (intel_ifs_0). During the loading stage, the driver will look for a file named ff-mm-ss-<batch02x>.sbft in the /lib/firmware/intel/ifs_2 directory. The hardware interaction needed for loading the image is similar to SAF, with the only difference being the MSR addresses used. Reuse the SAF image loading code, passing the SBAF-specific MSR addresses via struct ifs_test_msrs in the driver device data. Unlike SAF, the SBAF test image chunks are further divided into smaller logical entities called bundles. Since the SBAF test is initiated per bundle, cache the maximum number of bundles in the current image, which is used for iterating through bundles during SBAF test execution.

2024-08-12platform/x86/intel/ifs: Refactor MSR usage in IFS test codeKuppuswamy Sathyanarayanan
IFS tests such as Scan at Field (SAF) or Structural Based Functional Test at Field (SBAF), require the user to load a test image. The image loading process is similar across these tests, with the only difference being MSR addresses used. To reuse the code between these tests, remove the hard coding of MSR addresses and allow the driver to pass the MSR addresses per IFS test (via driver device data). Add a new structure named "struct ifs_test_msrs" to specify the test-specific MSR addresses. Each IFS test will provide this structure, enabling them to reuse the common code. This is a preliminary patch in preparation for the addition of SBAF support.

2024-08-12platform/x86: ISST: Simplify isst_misc_reg() and isst_misc_unreg()Srinivas Pandruvada
After commit '1630dc626c87 ("platform/x86: ISST: Add model specific loading for common module")' isst_misc_reg() and isst_misc_unreg() can be simplified. Since these functions are only called during module_init() and module_exit() respectively, there is no contention while calling misc_register()/misc_deregister or isst_if_cpu_info_init()/ isst_if_cpu_info_exit(). Hence remove mutex and reference counting.
