[PATCH v2 0/2] platform/x86: bitland-mifs-wmi: Xiaomi Book Pro 14 support
From: Chris Taraszka
Date: Sun Oct 25 2026 - 15:55:16 EST
Two patches on top of Mingyou Chen's v13 "Merge redmi-wmi into
bitland-mifs-wmi" [1], which adds the quirks table they build on.
Patch 1 adds the Xiaomi Book Pro 14 (TM2424) entry. Patch 2 stops
platform profile save/restore errors from failing system suspend or
resume.
Kento proposed a different mapping for the same board [2]: low-power
as 0x0a (which also dims the panel and keyboard backlight), balanced as
0x09, performance as 0x04 with 0x03 as fallback, and no
balanced-performance. This series keeps the four distinct firmware
modes and leaves 0x0a to the firmware's own mode cycling. Kento, if
this is a problem on BIOS 0707 or 0A0A, please say so.
Mingyou, on your v13 question: with 7/7, accept_zero_function is not
needed here. The entry does not set it and every SET succeeds.
Changes since v1 [3][4]:
- Use the quirks table from v13 instead of a DMI conditional in the code
- Match on board name TM2424 (Kento)
- Suspend fix also covers resume and skips the restore when nothing
was saved
