Hi Dan,
I hope you can fine to test this patch from Thomas. If this works then we can forget about my attempt to do the same.
I'll test this as soon as I can and let you know.
Thanks, crossing my fingers... (which explains the funny spelling from time to time)
SamSo I ran the test on an A5D27 XULT board with a PDA5 display. Our
graphics demos that come with our linux4sam releases seem to run just fine. modetest -v seems to run just fine. However, vbltest returns "drmWaitVBlank (relative) failed ret: -1". I don't understand why modetest -v is working and vbltest isn't, but that's what I'm seeing.
Thanks for testing.
Strange indeed.
Just to be sure... Can you confirm that vbltest is working OK *before* this patch?
Yes, can you please verify that it regressed. If so, this would mean that the driver misses vblank interrupts with the patch applied.
Best regards Thomas
Sam
