[Mesa-dev] [PATCH 3/3] i965: Move perf_debug code to brw_codegen_*_prog()

Kristian Høgsberg Kristensen krh at bitplanet.net
Wed Sep 9 10:44:13 PDT 2015


We're trying to avoid a libdrm dependency in the core compiler, so let's
move the perf_debug code one level up from the brw_*_emit() helpers to
the brw_codegen_*_prog() helpers.
