[Mesa-dev] [PATCH 1/2] r600: add simple ib dumping under a env var

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

I've used this a lot when developing, and keep rebasing it around a lot,
seems like it could be useful to have upstream.

R600_DUMP witll make lots of /tmp/rad_dump_<id>.txt for every command
submitted to the hw.
