[PATCH v7 0/5] Merge redmi-wmi into bitland-mifs-wmi
From: Mingyou Chen
Date: Wed Sep 30 2026 - 20:33:14 EST
This patch series consolidates the standalone 'redmi-wmi' driver into the
'bitland-mifs-wmi' driver to eliminate code duplication and centralize
the maintenance of overlapping ACPI WMI event streams.
Bitland is the ODM manufacturer for various Xiaomi Redmibook models. Both
platforms share the exact same keyboard event stream WMI GUID
(46C93E13-EE9B-4262-8488-563BCA757FEF). While redmi-wmi previously parsed
the 4-byte payload as a bulk u32 scancode, bitland-mifs-wmi deconstructed
it into discrete type/id/value fields.
Redmi operations were not contained in this patch series, future reverse
engineering is required.
This series introduce a newly reported mic-mute hotkey definition
for Redmibooks
and dropped the previous redmi-wmi driver.
I don't have a Redmi or other Bitland device. So I cannot work on the
real device.
Features are working properly on my device (Lecoo Bellator N176).
I leave the future reverse engineering work to the community.
v7:
Swap low bit and high bit for
WMI_EVENT_KBD_BRIGHTNESS in bitland_mifs_wmi_keymap
0x00800501 -> BI_HOTKEY_CODE(WMI_EVENT_KBD_BRIGHTNESS, 0x80, 0),
Report KEY_FN_ESC when WMI_EVENT_FNLOCK_STATE events received
Rename the reserved names
Use Xmas tree order in bitland_mifs_wmi_notify
Collect the Tested-by and Reviewed-by tags
v6:
Drop the wrong Redmi ops
v5:
Correct Xiaomi DMI vendor name
v4:
Map PLATFORM_PROFILE_PERFORMANCE to wmi performance mode if the device
doesn't support full-speed mode.
