Change Details

[[ https://github.com/coreboot/coreboot/blob/master/src/ec/google/chromeec/acpi/tbmc.asl | This ACPI device ]] exposed by the Chrome EC reports when a laptop-tablet convertible Chromebook (e.g., Google Pixelbook) is switched to tablet mode. Like on Linux, the reporting is via evdev: ``` -event3 SWITCH_TOGGLE +3.27s switch tablet-mode state 1 event3 SWITCH_TOGGLE +8.63s switch tablet-mode state 0 ``` though I can add more ways of notification (devd events I guess). [[ https://chromium-review.googlesource.com/c/chromiumos/third_party/coreboot/+/1060385 | Google will eventually replace this device with Intel Virtual Buttons ]] (used by [[ https://groups.google.com/a/chromium.org/forum/#!msg/chromium-os-checkins/IudkWWSvzC8/ztN2UdCUAQAJ | other convertibles ]]), but for now this exists. When I get my debug cable, I'll build firmware with that patch and write a driver for vbtn too. Is there a good way to autoload such things? (I guess not, since I've had to load `acpi_ibm` manually on Thinkpads)
