Thanks for feedback. I tested this and, indeed there are issues on 6SX with this particular patch. It seems that there is a race-condition caused by the vblank_on call in enable and IRQ routine. Since this is not happening on any of i.MX8 SoC, I suspect the axi clock usage. I think I will just remove this patch from the patch-set and handle this case separately. > > -- > Regards, > Leonard Regards, Robert _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
