| |
Hi
Using 4.9.133 on RS780 chipset (HD3200) with radeon.dpm=1 setting and noticed the following problem:
Reading gpu_reset through debug fs by issuing
sudo cat /sys/kernel/debug/dri/0/radeon_gpu_reset
causes GPU to reset and sometimes to freeze or garble screen output as you can see on screenshot, the value returned is always 0.
Shouldn't GPU reset only on echoing 1 to this register? [unhandled content-type:image/png] | |
