https://bugzilla.kernel.org/show_bug.cgi?id=94061 --- Comment #12 from mirh (m...@protonmail.ch) --- I see that [amdgpu_]kv_smc_bapm_enable is equivalent, but the condition guarding it seems quite different. Then I'm not really pretending to understand much else about the two kv_dpms. -- You

https://bugzilla.kernel.org/show_bug.cgi?id=94061 --- Comment #7 from Klaus Maier --- Tested your suggestion to activate the powergating by removing the comments you mentioned above w/ 3.19.3 and radeon.bapm=1. This even raised the power consumption about 5 W more as w/o it. This "feature" is

https://bugzilla.kernel.org/show_bug.cgi?id=94061 --- Comment #6 from Klaus Maier --- radeon.bapm=1 brings back the originally reported behaviour (based on 3.14). I didn't enable rdev->cg_flags and rdev->pg_flags as it is already known to be broken because it needs a complete kernel recompile.

https://bugzilla.kernel.org/show_bug.cgi?id=94061 --- Comment #2 from Klaus Maier --- Yes - backlight management is switched off because it doesn't work at all w/ catalyst. Always full. Brightness, ... - it's all configured by the monitor itself. Management via KDE or software is done only for
