[Intel-gfx] [PATCH i-g-t v2] benchmark/: fix gem_exec_nop complie error on android
Derek Morton
derek.j.morton at intel.com
Fri Jul 24 06:35:29 PDT 2015
There are two versions of gem_exec_nop.c in benchmarks and tests
which causes the build system to have two build modules with
the same name.
This patch renames benchmarks/gem_exec_nop.c to
benchmarks/gem_exec_nop_benchmark.c using the existing
gem_userptr_benchmark.c as a naming convention.
v2: Also rename gem_mmap to gem_mmap_benchmark. Another file
which breaks android which was added after this patch was 1st
submitted.
