[Mesa-dev] radeonsi: ppc64 glamor backtrace

[Jack Mitchell]

Hi,

I'm trying to run a VERDE based AMD card in a big endian powerpc64. I
can get everything working with swrast but when I try to enable
acceleration mesa bombs out when starting Xorg. I've got a backtrace
from gdb but I'm not sure where to go next in debugging, any pointers
would be appreciated.

Regards,
Jack.
