            Bug ID: 100446
           Summary: Backlight control not working on Pascal / GP106 using
                    nouveau drivers
           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: carlo-KA+7E9HrN00dnm+yROfE0A@public.gmane.org

I'm currently working on an ASUS GL702VMK. This machine is shipping a GeForce
GTX 1060 GP106 (136000a1) connected to an internal DisplayPort on DFP-5 (usual
AU Optronics Corporation).

Using the unmodified latest nouveau drivers I have no backlight control.
Modifying nouveau_backlight.c adding a case for NV_DEVICE_INFO_V0_PASCAL I
finally get /sys/class/backlight/nv_backlight/ but changing the backlight value
in there is not working anyway.

Trying to manually poke NV50_PDISP_SOR_PWM_CTL(1) with `nvapoke` has no effect
whatsoever on the brightness (on or==1)

Backlight control is not working using the proprietary 375 / 378 drivers
either. Also in this case the value of NV50_PDISP_SOR_PWM_CTL is actually
changed by `xbacklight` but with no visible effect.

Any hint?
