[Mesa-dev] [PATCH 4/6] broadcom: Add vc5 CLIF dumping
Eric Anholt

Sat Aug 19 00:13:46 UTC 2017
This will be usable with "VC5_DEBUG=cl" on the vc5 driver to stream a CLIF
file (the Broadcom equivalent of i965's AUB) to stderr. I haven't tested
that this is actually usable with the internal CLIF-consuming tools, but
is close enough as a baseline and is useful for visually inspecting the
command stream.
