From: Kenneth Graunke Date: Wed, 14 Aug 2013 23:07:51 +0000 (-0700) Subject: i965: Dump more information about batch buffer usage. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e29931aa7423209d29a23be2ad754abb0f79315e;p=mesa.git i965: Dump more information about batch buffer usage. Previously, INTEL_DEBUG=bat would dump messages like: intel_mipmap_tree.c:1643: Batchbuffer flush with 456b used This only reported the space used for command packets, and didn't report any information on the space used for indirect state. Now it dumps: intel_context.c:366: Batchbuffer flush with 6128b (pkt) + 4288b (state) = 10416b (31.8%) This conveniently shows the breakdown of space used for packets vs. state, as well as the percentage of batchbuffer space.
