--- Comment #25 from Simon Farnsworth <[email protected]> 2011-12-07 06:49:01 PST --- Alex Deucher has given me data on Evergreen tiling, which has allowed me to get to the bottom of this: Evergreen doesn't have one fixed 2D tiling pattern; it has configurable per-surface 2D tiling. There are restrictions on which tiling options work together; the DDX and the kernel currently ignore those. Doing the math, the worst case alignment required for 2D tiling is 2 megabyte alignment on my hardware. The settings used for the scanout buffer are marked in Alex's information as illegal - this will be why I need excessive alignment to make it appear to function. It looks like fixing this is going to require changes across the stack - rather than simply attaching patches to this bug, I will send them to appropriate mailing lists. (xorg-driver-ati for DDX patches, dri-devel for the kernel, mesa-dev for Mesa). -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
