In the non-timeout case in recv_ec_data_timeout, a message like this one will get printed at BIOS_SPEW log level: "recv_ec_data_timeout: 0x00". The "timeout" part of the function name corresponds to what the function does, but the message will only be printed when not running into the timeout which is a bit misleading and might suggest a problem when there is none. To avoid this possible confusion, don't use the function name in the printk, but use "Data from EC:" instead.

This reverts commit 4dba71fd25c91a9e610287c61238a8fe24452e4e. Add multiple fan support for dptf policies. This also fixes the Google Meet resolution drop issue as per b:246535768 comment#12. When system starts Google Meet video call, it uses the hardware accelerated encoder as expected. But, as soon as another system connects to the call, an immediate fallback is observed from hardware to software encoder. Due to this, Google Meet resolution dropped from 720p to 180p. This issue is observed on Alder Lake-N SoC based fanless platforms. This same issue was not seen on fan based systems. With the fix in dptf driver where fan configures appropriate setting for only fan participant, not for other device participants, able to see consistent 720p resolution. BUG=b:246535768,b:235254828 BRANCH=None TEST=Built and tested on Alder Lake-P Redrix system for two fans support and on Alder Lake-N fanless systems.

2023-04-12ec/google/chromeec: Use either EC or MB lid switch stateKarthikeyan Ramasubramanian
With CB:16732, EC can provide default lid switch implementation(LID0 ACPI device). Up until that point, mainboard has been providing default switch implementation. When EC provides lid switch implementation, the lid switch state is read from EC either through MMAP or LPC interface. Hence there is no need to keep mainboard's LIDS ACPI object in sync with EC's lid switch state. Use only EC's lid switch state on boards using EC's implementation. This paves the way to remove LIDS ACPI object on those mainboards. BUG=None TEST=Build Skyrim BIOS image and boot to OS. Trigger lid open/close events and ensure that they are detected properly through /proc/acpi/button/lid/LID0/state. localhost ~ # cat /proc/acpi/button/lid/LID0/state state: open localhost ~ # cat /proc/acpi/button/lid/LID0/state state: closed Ensure that the system behaves as expected based on powerd configuration.

This reverts commit b42ca4d0b2fafe7214396d30a1a833ac33cf85bc. Reason for revert: The mirror flag "0x01" is mirror once, which relies on the EC remembering that it's been mirrored. However, the EC forgets this if it's been without power for 20 minutes or so. Even if power is connected then, it'll instantly try to mirror and it can't charge whilst doing it. It can either result in incomplete EC firmware, or a loop where it's constantly trying to mirror.

Handle the new host event EC_HOST_EVENT_BODY_DETECT_CHANGE. Previously, the EC sent the host event EC_HOST_EVENT_MODE_CHANGE when body detection changed between lap/desk mode. However, that event is a wake event, which resulted in spurious AP wake events being triggered when the EC detected lap/desk mode changes while the AP was suspended. To resolve this, the new host event EC_HOST_EVENT_BODY_DETECT_CHANGE was added, which will not be a wake event.

However this is not the case for Chromebox, Chromebox EC set AP_IDLE flag when system is shutting down, when AP_IDLE flag is set in EC, the system stays at S5/G3 and wait for power button presssend. It cause an issue in factory that the operator needs to press power button to power on the DUT after Cr50 firmware update.

2022-11-11ec/clevo/it5570e: add driver for EC used on various Clevo laptopsMichael Niewöhner
This adds a driver for the ITE IT5570E EC in combination with Clevo vendor EC firmware. The interface is mostly identical on various laptop models. Thus, we have implemented one common driver to support them all. The following features were implemented: - Basics like battery, ac, etc. - Suspend/hibernate support: S0ix, S3*, S4/S5 - Save/restore of keyboard backlight level during S0ix without the need for Clevo vendor software (ControlCenter) - Flexicharger - Fn keys (backlight, volume, airplane etc.) - Various configuration options via Kconfig / CMOS options * Note: S3 support works at least on L140CU (Cometlake), but it's not enabled for this board because S0ix is used. Not implemented, yet: - Type-C UCSI: the EC firmware seems to be buggy (with vendor fw, too) - dGPU support is WIP An example of how this driver can be hooked up by a board can be seen in in change CB:59850, where support for the L140MU is added. Known issues: - Touchpad toggle: The touchpad toggle (Fn-F1) has two modes, Ctrl-Alt-F9 mode and keycodes 0xf7/0xf8 mode. Ctrl-Alt-F9 is the native touchpad toggle shortcut on Windows. On Linux this would switch to virtual console 9, if enabled. Thus, one should use the keycodes mode and add udev rules as specified in [1]. If VT9 is disabled, Ctrl-Alt-F9 mode could be used to set up a keyboard shortcut command toggling the touchpad. - Multi-fan systems The Clevo NV41MZ (w/o dGPU) has two fans that should be in-sync. However, the second fan does not spin. This needs further investigation. [1] https://docs.dasharo.com/variants/clevo_nv41/post_install/ Testing the various functionalities of this EC driver was done in the changes hooking up this driver for the boards.

Simplify the implementation of setting the keyboard backlight PWM value. Host command stubs typcially don't need to examine the host command's return value as stored in cmd_code because that level of detail is not very interesting. Higher value error codes are returned in actual result structures. This host command can return EC_RES_ERROR for out of range PWM values which is already a generic error and unlikely to happen since we already limit the range to 0..100 here. Finally, none of the callers in coreboot check the return value.

2022-10-20Revert "drivers/intel/dptf: Add multiple fan support under dptf"Sumeet Pawnikar
This reverts commit 672bd9bee5c0045694ef20fe3e2f7a003bef0edd. Reason for revert: Gmeet resolution dropped. When system starts Gmeet video call, it uses the hardware accelerated encoder as per the expectation. But, as soon as another system connects to the call, the immediate fallback observed from hardware to software encoder. Due to this, Gmeet resolution dropped from 720p to 180p. Currently, this issue observed on AlderLake-N SoC based fanless platforms. This issue is not seen on fan based systems.

2022-07-14commonlib: Substitude macro "__unused" in compiler.hBill XIE
Since there are many identifiers whose name contain "__unused" in headers of musl libc, introducing a macro which expands "__unused" to the source of a util may have disastrous effect during its compiling under a musl-based platform. However, it is hard to detect musl at build time as musl is notorious for having explicitly been refusing to add a macro like "__MUSL__" to announce its own presence. Using __always_unused and __maybe_unused for everything may be a good idea. This is how it works in the Linux kernel, so that would at least make us match some other standard rather than doing our own thing (especially since the other compiler.h shorthand macros are also inspired by Linux).
