I grep-ed amdgpu displayport atombios code, got udelay(400) only. Did the same on drm *_dp_* files, got similar udelays with only a very slow msleep (which seems justified there). But I did not get any udelays with the range of 1ms for "retries". Maybe it would be a good idea to a similar delay on non-DC displayport code? That would give more time to "slow" displayort monitors to timeout on their side. -- Sylvain _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
