Subject: [Bug 215177] New: Stop exporting platform_profile interface for Lenovo T14/P14s Gen2 AMD
Date: Tue, 30 Nov 2021 16:20:48 +0000 [thread overview]
Message-ID: <bug-215177-215701@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=215177
Bug ID: 215177
Summary: Stop exporting platform_profile interface for Lenovo
T14/P14s Gen2 AMD
Product: Drivers
Version: 2.5
Kernel Version: 5.15.5
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Platform_x86
Assignee: drivers_platform_x86@kernel-bugs.osdl.org
Reporter: bjoern.daase@gmail.com
Regression: No
The T14/P14s Gen2 AMD (and maybe more?) have a completely broken platform
profile implementation. While advertising three profiles, they do not change
anything. See
https://forums.lenovo.com/t5/Other-Linux-Discussions/T14-AMD-subpar-CPU-performance/m-p/5089829?page=1#5386521
for details.
As some user space software (e.g. platform-profiles-daemon) expects them to
work correctly when they are available, they should not be exported for broken
devices.
Therefore, I suggest to stop exporting a platform_profile interface for the
Lenovo T14/P14s Gen2 AMD.
