Bug ID: 207137
Summary: AMDGPU incorrectly reports vddgfx voltage for R9 390
Product: Drivers
Version: 2.5
Kernel Version: 5.6
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: low
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: sandy.8925@gmail.com
Regression: No
I'm using an R9 390 GPU.
vddgfx voltage is always reported as 1 Volt, regardless of load.
I debugged and found that in smu7_hwmgr.c , in funcion smu7_read_sensor(), the
voltage is read from PLANE2_VID when a certain condition is true. This always
results in a final value of 1 Volt.
When I changed the code to read only from PLANE1_VID, the correct voltage seems
to be reported, and it changes under load, from ~900 mv to 1.3 V.
Please fix.
