2024-12-30platform/chrome: cros_ec: jump to RW before probingDawid Niedzwiecki
There are EC devices, like FPMCU, that use RWSIG as a method of authenticating RW section. After the authentication succeeds, EC device waits some time before jumping to RW. EC can be probed before the jump, which means there is a time window after jump to RW in which EC won't respond, because it is not initialized. It can cause a communication errors after probing. To avoid such problems, send the RWSIG continue command first, which skips waiting for the jump to RW. Send the command more times, to make sure EC is ready in RW before the start of the actual probing process. If a EC device doesn't support the RWSIG, it will respond with invalid command error code and probing will continue as usual.

2024-12-29platform/x86: hp-wmi: mark 8A15 board for timed OMEN thermal profileMingcong Bai
The HP OMEN 8 (2022), corresponding to a board ID of 8A15, supports OMEN thermal profile and requires the timed profile quirk. Upon adding this ID to both the omen_thermal_profile_boards and omen_timed_thermal_profile_boards, significant bump in performance can be observed. For instance, SilverBench (https://silver.urih.com/) results improved from ~56,000 to ~69,000, as a result of higher power draws (and thus core frequencies) whilst under load: Package Power: - Before the patch: ~65W (dropping to about 55W under sustained load). - After the patch: ~115W (dropping to about 105W under sustained load). Core Power: - Before: ~60W (ditto above). - After: ~108W (ditto above). Add 8A15 to omen_thermal_profile_boards and omen_timed_thermal_profile_boards to improve performance.

2024-12-24platform/chrome: cros_ec_typec: Disable tbt on portAbhishek Pandit-Subedi
Altmodes with cros_ec are either automatically entered by the EC or entered by the AP if TBT or USB4 are supported on the system. Due to the security risk of PCIe tunneling, TBT modes should not be auto entered by the kernel at this time and will require user intervention. With this change, a userspace program will need to explicitly activate the thunderbolt mode on the port and partner in order to enter the mode and the thunderbolt driver will not automatically enter when a partner is connected.

2024-12-17platform/x86: dell-smo8800: Move instantiation of lis3lv02d i2c_client from ↵Hans de Goede
i2c-i801 to dell-lis3lv02d Various Dell laptops have an lis3lv02d freefall/accelerometer sensor. The lis3lv02d chip has an interrupt line as well as an I2C connection to the system's main SMBus. The lis3lv02d is described in the ACPI tables by an SMO88xx ACPI device, but the SMO88xx ACPI fwnodes are incomplete and only list an IRQ resource. So far this has been worked around with some SMO88xx specific quirk code in the generic i2c-i801 driver, but it is not necessary to handle the Dell specific instantiation of i2c_client-s for SMO88xx ACPI devices there. The kernel already instantiates platform_device-s for these with an acpi:SMO88xx modalias. The drivers/platform/x86/dell/dell-smo8800.c driver binds to this platform device but this only deals with the interrupt resource. Add a drivers/platform/x86/dell/dell-lis3lv02d.c which will matches on the same acpi:SMO88xx modaliases and move the i2c_client instantiation from the generic i2c-i801 driver there. Moving the i2c_client instantiation has the following advantages: 1. This moves the SMO88xx ACPI device quirk handling away from the generic i2c-i801 module which is loaded on all Intel x86 machines to a module which will only be loaded when there is an ACPI SMO88xx device. 2. This removes the duplication of the SMO88xx ACPI Hardware ID (HID) table between the i2c-i801 and dell-smo8800 drivers. 3. This allows extending the quirk handling by adding new code and related module parameters to the dell-lis3lv02d driver, without needing to modify the i2c-i801 code.
