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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
