Comment # 12
on bug 61182
from Alex Deucher
I think these are actually several bugs at play here. 1. CPU only has a 256 MB window into vram. If the window is full due to fragmentation or other mapped buffers, we fail. Does disabling hyperz help? set env var R600_HYPERZ=0 (mesa 9.1 or older), or R600_DEBUG=nohyperz (mesa git). 2. running out of GPU accessible memory when migrating buffers. Does setting radeon.gartsize=1024 on the kernel command line in grub help?
