Re: amdgpu: Manual Card Configuration Change
Thanks. I tried 5.9.1 and I think there's still a problem, or at least something different. Using the same configuration script, I noticed that my cards are running a lot hotter. For example, here's total power consumption of a two-card system with two different kernels: 5.8.14: 460W 5.9.1: 560+W Memory and system clocks are initially set the same on all cards in all cases.

amdgpu: Manual Card Configuration Change
Hello all, Regarding amdgpu, I've been using some Radeon 5700XTs for compute work with kernels through 5.8.14. I recently tried kernel 5.9.0, and found that the following is no longer allowed: echo "m 1 200" | sudo tee /sys/class/drm/card0/device/pp_od_clk_voltage Is this an expected change? If so, where should I look for documentation regarding how to manually configure these cards with this kernel. Note, I've had this working with 5.8 kernels for months.
