On the X380 Yoga, the `ECRD` and `ECWR` ACPI objects cannot be used for accessing the Embedded Controller: instead of a method that reads from the EC's memory, `ECRD` is the name of a location in high memory. This meant that trying to call them would fail with the following message: ACPI: \_SB.PCI0.LPCB.EC.ECRD: 1 arguments were passed to a non-method ACPI object (RegionField) With this commit, it is now possible to access the EC and read temperature and fan speed information. Note that while writes to the HFSP register do go through (as indicated by subsequent reads showing the new value), the fan does not actually change its speed. Signed-off-by:

Both the Lenovo Yoga Tablet 2 830 and 1050 models use an TI LP8557 LED backlight controller. On the 1050 the LP8557's PWM input is connected to the PMIC's PWM output and everything works fine with the defaults programmed into the LP8557 by the BIOS. But on the 830 the LP8557's PWM input is connected to a PWM output coming from the LCD panel's controller. The Android code has a hack in the i915 driver to write the non-standard DSI reg 0x9f with the desired backlight level to set the duty-cycle of the LCD's PWM output. To avoid having to have a similar hack in the mainline kernel the LP8557 entry in lenovo_yoga_tab2_830_1050_i2c_clients instead just programs the LP8557 to directly set the level, ignoring the PWM input. So far we have only been instantiating the LP8557 i2c_client for direct backlight control on the 830 model. But we want hide/disable the intel_backlight interface on the 830 model to avoid having 2 backlight interfaces for the same LCD panel. And the 830 and 1050 share the same DMI strings. So this will hide the intel_backlight interface on the 1050 model too. To avoid this causing problems make the backlight handling consistent between the 2 models and always directly use the LP8557. This also simplifies the code. Signed-off-by:

Gergo Koteles authored
This WMI driver for the tablet mode control switch for Lenovo Yoga notebooks was originally written by Gergo Koteles. The mode is mapped to a SW_TABLET_MODE switch capable input device. Andrew followed the suggestions that were posted in reply to Gergo's RFC patch, and on the v1 & v2 versions of this patch to follow-up and get it merged. Changes from Gergo's RFC: - Refactored obtaining a reference to the EC ACPI device needed for the quirk implementation as suggested by Hans de Goede - Applied small fixes and switched to always registering handles with the driver for automatic cleanup as suggested by Barnabás Pőcze. - Merged the lenovo_ymc_trigger_ec function with the ideapad_trigger_ymc_next_read function since it was no longer external. - Added the word "Tablet" to the driver description to hopefully make it more clear. - Fixed the LENOVO_YMC_QUERY_METHOD ID and the name string for the EC APCI device trigged for the quirk - Triggered the input event on probe so that the initial tablet mode state when the driver is loaded is reported to userspace as suggested by Armin Wolf. - Restricted the permissions of the ec_trigger parameter as suggested by Armin Wolf. Also updated the description. We have tested this on the Yoga 7 14AIL7 for the non-quirk path and on the Yoga 7 14ARB7 which has the firmware bug that requires triggering the embedded controller to send the mode change events. This workaround is also used by the Windows drivers. According to reports at https://github.com/lukas-w/yoga-usage-mode, which uses the same WMI devices, the following models should also work: Yoga C940, Ideapad flex 14API, Yoga 9 14IAP7, Yoga 7 14ARB7, etc. Signed-off-by:

Array BIST test (for a particular core) is triggered by writing to MSR_ARRAY_BIST from one sibling of the core. This will initiate a test for all supported arrays on that CPU. Array BIST test may be aborted before completing all the arrays in the event of an interrupt or other reasons. In this case, kernel will restart the test from that point onwards. Array test will also be aborted when the test fails, in which case the test is stopped immediately without further retry. Signed-off-by:

Array BIST is a new type of core test introduced under the Intel Infield Scan (IFS) suite of tests. Emerald Rapids (EMR) is the first CPU to support Array BIST. Array BIST performs tests on some portions of the core logic such as caches and register files. These are different portions of the silicon compared to the parts tested by the first test type i.e Scan at Field (SAF). Make changes in the device driver init flow to register this new test type with the device driver framework. Each test will have its own sysfs directory (intel_ifs_0 , intel_ifs_1) under misc hierarchy to accommodate for the differences in test type and how they are initiated. Upcoming patches will add actual support. Signed-off-by:

The struct holding device driver data contained both read only(ro) and read write(rw) fields. Separating ro fields from rw fields was recommended as a preferable design pattern during review[1]. Group ro fields into a separate const struct. Associate it to the miscdevice being registered by keeping its pointer in the same container struct as the miscdevice.

In preparation to supporting additional tests, remove ifs_pkg_auth from per-test scope, as it is only applicable for one test type. This will simplify ifs_init() flow when multiple tests are added. Signed-off-by:

Add a new driver to allow various MSI laptops' functionalities to be controlled from userspace. This includes such features as power profiles (aka shift modes), fan speed, charge thresholds, LEDs, etc. This driver contains EC memory configurations for different firmware versions and exports battery charge thresholds to userspace (note, that start and end thresholds control the same EC parameter and are always 10% apart).

Summary of changes: Till the commit: "tools/power/x86/intel-speed-select: Get punit core mapping information" All patches just lays foundation for adding new hardware interface in addition to existing MSR/MMIO interface. All patches prefixed with "Abstract" just adds individual hardware callback for functions called from the core processing. The mailbox processing is abstracted to a new file with callbacks. In addition some changes to reduce duplicated code for display of TRL level. Patch "Introduce Punit ID concept and add related API" add further abstraction in addition to existing package and die scope. ----------- tools/power/x86/intel-speed-select: Get punit core mapping information -Adds a new way to get package/die/punit information for each CPU. ----------- Introduce TPMI interface support - Implement all abstracted callbacks above to use TPMI IOCTL interface. ----------- tools/power/x86/intel-speed-select: Display punit info - With TPMI the granularity is per punit, which can be multiple in a package/die. ---------- tools/power/x86/intel-speed-select: Remove cpu mask display for non-cpu power domain tools/power/x86/intel-speed-select: Display fact info for non-cpu power domain -There are some power domains with no CPUs, the above patches adds CPU as invalid for these domains ---------- tools/power/x86/intel-speed-select: Use cgroup v2 isolation - Adds new option to use Cgroup CPU isolation instead of offline of CPUs ---------- tools/power/x86/intel-speed-select: Change TRL display for Emerald Rapids - Emerald Rapid has multiple TRL levels and moves away from TRL level based on instruction type
