[Intel-gfx] [PATCH i-g-t v4 3/3] tests/gem_concurrent_all: Remove gem_concurrent_all.c

David Weinehall david.weinehall at linux.intel.com
Thu Feb 11 11:09:34 UTC 2016


When gem_concurrent_blit was converted to use the new common framework
for choosing whether or not to include slow/combinatorial tests,
gem_concurrent_all became superfluous.  This patch removes it.
