From: Denis 'GNUtoo' Carikli <[email protected]> The si.c file also needed to be patched to avoid the following probe failure due to the missing MC firmrware: [drm:si_startup [radeon]] *ERROR* Failed to load MC firmware! radeon 0000:02:00.0: disabling GPU acceleration radeon 0000:02:00.0: 00000000b8c27aec unpin not necessary [drm:si_init [radeon]] *ERROR* radeon: MC ucode required for NI+. radeon 0000:02:00.0: Fatal error during GPU init [...] radeon: probe of 0000:02:00.0 failed with error -22
This has been tested with the following GPU: 02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cape Verde PRO [Radeon HD 7750/8740 / R7 250E] [1002:683f] Xorg, lightdm, xfce4, mplayer and wesnoth have been tested and work fine, though in mplayer the OSD has some light artefacts.
