I was just re-looking at the acceleration disabled on my Radeon R5 240 thing again. It is still working fine for me on 6.0 with acceleration on.
The specific commit that disabled acceleration is here: https://gitweb.dragonflybsd.org/dragonfly.git/commitdiff/e8de9e94be61d3d50fc134bbde36c014f25a6a56?hp=1dedbd3b06c68f627b7825694444529d5eb2b1bf (e8de9e94be61d3d50fc134bbde36c014f25a6a56) I re-enabled acceleration by just reversing the diff. -Bill On Mon, Jul 5, 2021 at 7:45 AM karu.pruun <karu.pr...@gmail.com> wrote: > > It seems not all radeon cards work with GPU acceleration, for instance > I get the following w/o the commit you mention > > kernel: error: [drm:pid223:r600_dma_ring_test] *ERROR* radeon: ring 3 > test failed (0xCAFEDEAD) > kernel: drm0: error: disabling GPU acceleration > > for both Radeon R7 370 and R7 360.
