And here values from requested files without "amdgpu.dc=1"
"/sys/class/backlight/amdgpu_bl0 # ls -l
razem 0
-r--r--r-- 1 root root 4096 02-22 17:50 actual_brightness
-rw-r--r-- 1 root root 4096 02-22 17:50 bl_power

"/sys/class/backlight/amdgpu_bl0 # cat brightness
23"
"/sys/class/backlight/amdgpu_bl0 # cat actual_brightness
23"
"/sys/class/backlight/amdgpu_bl0 # cat max_brightness
255"
With smaller values from previous post (with "amdgpu.dc=1" on kernel
commandline) screen is much brighter, as backlight was set almost 100%.
