--- Comment #78 from Dieter Nützel Dieter@nuetzel-hh.de --- (In reply to Gustaw Smolarczyk from comment #77)
No pauses after I applied attachment 166571 [details] and "drm/radeon: do a posting read in si_set_irq" from posting-read branch on top of v3.19. So I guess these commits combined fix this issue.
@Dieter: I did not need to apply this patch in order to fix this issue.
Thanks Gustaw!
In the meantime I have it running on r600g/NI/Turks XT with:
drm-next-4.1-wip + HDMI fixes from 'audio-fixes' + ' posting-read' drm-radeon-do-a-posting-read-in-evergreen_set_irq.patch drm-radeon-do-a-posting-read-in-r600_set_irq.patch (better more than less...;-) + attachment 166571 drm-radeon-fix-wait-to-actually-occur-after-the-signaling-callback.patch + drm-radeon-fix-DRM_IOCTL_RADEON_CS-oops.patch
Cheers, Dieter
