[Bug 105664] AMD HAINAN (Radeon R5 M330) Clock frequency is 750MHz while it is supposed to be 1030MHz
https://bugs.freedesktop.org/show_bug.cgi?id=105664
Bug ID: 105664 Summary: AMD HAINAN (Radeon R5 M330) Clock frequency is 750MHz while it is supposed to be 1030MHz Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon Assignee: dri-devel@lists.freedesktop.org Reporter: yassine10suno@gmail.com
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 the default frequency this GPU is designed for**.

--- Comment #2 from Alex Deucher alexdeucher@gmail.com --- A number of boards had stability issues at the default clocks. Please attach your dmesg output.

Note: I have not modified the kernel dmesg was ran under. Core clock is still 750MHz.

--- Comment #5 from Yassine Oudjana y.oudjana@protonmail.com --- Why is the core clock for this GPU (HAINAN) and what seems to have codename OLAND hard-coded anyway? The other GPUs do not have their clocks hard-coded, which allows them to be modified without modifying and rebuilding the module.
