fixed patch
I fixed the patch and can apply it on top of amd-drm-next and vanilla kernel
5.0.11 (my current kernel). Unfortunately it doesn't help. I added 'verbose
debug' patch too, here is my output.
1) Before applying high memory profile workaround:
kernel: amdgpu: [powerplay] min_core_set_clock: 30000
kernel: amdgpu: [powerplay] min_mem_set_clock: 30000
kernel: amdgpu: [powerplay] vrefresh: 75
kernel: amdgpu: [powerplay] min_vblank_time: 464
kernel: amdgpu: [powerplay] num_display: 2
kernel: amdgpu: [powerplay] multi_monitor_in_sync: 0
kernel: amdgpu: [powerplay] performance level 0 memory clock = 30000
kernel: amdgpu: [powerplay] performance level 0 engine clock = 30000
kernel: amdgpu: [powerplay] performance level 1 memory clock = 200000
kernel: amdgpu: [powerplay] performance level 1 engine clock = 136600
kernel: amdgpu: [powerplay] mclk_latency_table entry0 frequency = 30000
kernel: amdgpu: [powerplay] mclk_latency_table entry0 latency = 330
kernel: amdgpu: [powerplay] mclk_latency_table entry1 frequency = 100000
kernel: amdgpu: [powerplay] mclk_latency_table entry1 latency = 330
kernel: amdgpu: [powerplay] mclk_latency_table entry2 frequency = 200000
kernel: amdgpu: [powerplay] mclk_latency_table entry2 latency = 330
2) After:
kernel: amdgpu: [powerplay] min_core_set_clock: 30000
kernel: amdgpu: [powerplay] min_mem_set_clock: 30000
kernel: amdgpu: [powerplay] vrefresh: 75
kernel: amdgpu: [powerplay] min_vblank_time: 464
kernel: amdgpu: [powerplay] num_display: 2
kernel: amdgpu: [powerplay] multi_monitor_in_sync: 0
kernel: amdgpu: [powerplay] performance level 0 memory clock = 200000
kernel: amdgpu: [powerplay] performance level 0 engine clock = 30000
kernel: amdgpu: [powerplay] performance level 1 memory clock = 200000
kernel: amdgpu: [powerplay] performance level 1 engine clock = 136600
kernel: amdgpu: [powerplay] mclk_latency_table entry0 frequency = 30000
kernel: amdgpu: [powerplay] mclk_latency_table entry0 latency = 330
kernel: amdgpu: [powerplay] mclk_latency_table entry1 frequency = 100000
kernel: amdgpu: [powerplay] mclk_latency_table entry1 latency = 330
kernel: amdgpu: [powerplay] mclk_latency_table entry2 frequency = 200000
kernel: amdgpu: [powerplay] mclk_latency_table entry2 latency = 330
