Title:
AMD HAINAN (Radeon R5 M330) Clock frequency is 750MHz while it is
supposed to be 1030MHz
Status in linux package in Ubuntu:
Confirmed
Bug description:
Kernel source: /drivers/gpu/drm/radeon/si_dpm.c line 2985:
max_sclk = 75000;
instead of
max_sclk = 103000;
Why is that? I changed it and rebuilt the kernel, and I can say that
there are absolutely no issues when using the 1030MHz clock, which is
what it is supposed to be.
