PC Drivers & Software

[lapsio]

Do AMD Linux drivers support native 30 bit color depth (10 bit per channel) over DisplayPort? What are software requirements to get 10 bit color opengl running? I'm talking about X server (Xorg) and driver configuration alone as I already have everything else configured and working properly with old Quadro card. I never used AMD cards before, do they have similar xorg.conf options where I can just set Depth to 30 or something?

Does AMD support 10 bit emulation by dithering on 8 bit panels?

Which graphics card, which OS and which application?

OpenSUSE / SLES, may be changed to CentOS 7 if it's required. Radeon Pro W7100, Xorg itself but if we're talking about specific application then I tested support in Krita using OpenGL renderer because it supports 10bit if it's important.

As I said I'll be replacing "bottom" so I think gpu drivers and Xorg config. Everything's "above" is already configured properly to utilize 10bit and has been tested using old Quadro 4000 with positive results.
