(Archlinux, mesa/amdgpu) Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 7bit Minimum power limit on latest(6.7+) kernels is 190W for my GPU (RX 6700XT, mesa, archlinux) and I cannot get power cap as low as before(to 115W), neither with Corectrl, LACT or TuxClocker and /sys have a variable read-only even for root. This is not of above apps issue but of the kernel, I read similar issues from other bug reports of above apps. I downgraded to v6.6.10 kernel and my 115W(under power)cap work again as before. Please bring the low range back as efficiency vs power consumption is significant(links were not allowed, I posted in reddit's Linux sub about it and I am going to gitlab's drm/amd as well, but its like 90W and < 10% performance tradeoff).
