Comme= nt # 10 on bug 10654= 8 from Francesco Balestr= ieri

Indeed, after some more investigation I found out that the tes=
t case uses (via
MDAPI) the root-only interface:

/sys/devices/pci0000:00/0000:00:02.0/drm/card0/gt_boost_freq_mhz
/sys/devices/pci0000:00/0000:00:02.0/drm/card0/gt_max_freq_mhz
/sys/devices/pci0000:00/0000:00:02.0/drm/card0/gt_min_freq_mhz=20

to ask the kernel to maintain a static GPU frequency, and then reads it bac=
k to
check that it stays within a range of the requested value. The test fails
because the value it reads back is not what it requested (reproduced with
drm-tip). I still don't have dmesg output with debug logs enabled but I'l t=
ry
to get it next week.

For the records, this is what the test prints out once it is run as root:

[ RUN      ] GfxDrv_DriverAcceptanceQuery.GL_GPU_FREQ_OVERRIDE_MDAPI
