Change in ...coreboot[master]: [UNTESTED]drivers/lenovo/wacom: Move ssdt generator to nsc/pc87382

Arthur Heymans has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/33789 Change subject: [UNTESTED]drivers/lenovo/wacom: Move ssdt generator to nsc/pc87382 ...................................................................... [UNTESTED]drivers/lenovo/wacom: Move ssdt generator to nsc/pc87382 This adds a hook to the pc87382 code to specify the ACPI _HID in the case that a wacom device is hooked up to it. TODO: - the wacom code needs to know quite a lot about the SIO and has weird Kconfig hooks to force stuff that is bound to no work. - Add a function to detect the sio and disable it, if not found.

Evgeny Zinoviev has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/33052 Change subject: util/smctool: A tool for reading Apple SMC keys ...................................................................... util/smctool: A tool for reading Apple SMC keys SMC is an embedded controller on Apple computers. With this tool you can read SMC keys. It supports various data types and can output result in various formats. Example how to get battery capacity level: smctool -k B0FC -t ui16 # returns Full Capacity of Battery 0 smctool -k B0RM -t ui16 # returns Remaining Capacity of Batery 0 So B0RM / B0FC * 100 = battery capacity in percents. Another example, reading current fan speed, which is returned as unsigned fixed point number: sudo ./smctool -k F0Ac -t fpe2 Change-Id: I6161203e52b7f7eaa1205de06e8241d7d40a7481 Signed-off-by: Evgeny Zinoviev <me(a)ch1p.io> --- A util/smctool/Makefile A util/smctool/description.md A util/smctool/smc.c A util/smctool/smc.h A util/smctool/smctool.c 5 files changed, 538 insertions(+), 0 deletions(-) git pull ssh://review.coreboot.org:29418/coreboot refs/changes/52/33052/1 diff --git a/util/smctool/Makefile b/util/smctool/Makefile new file mode 100644 index 0000000..ce7cca2 --- /dev/null +++ b/util/smctool/Makefile @@ -0,0 +1,38 @@ +## +## Makefile for smctool +## +## Copyright (C) 2019 Evgeny Zinoviev <me(a)ch1p.io> +## +## This program is free software; you can redistribute it and/or modify +## it under the terms of the GNU General Public License as published by +## the Free Software Foundation; version 2 of the License. +## +## This program is distributed in the hope that it will be useful, +## but WITHOUT ANY WARRANTY; without even the implied warranty of +## MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
