# These tests all read from the front buffer after a swap.  Given that we
# run piglit tests in parallel in Mesa CI, and don't have a compositor
# running, the frontbuffer reads may end up with undefined results from
# windows overlapping us.
#
# Piglit does mark these tests as not to be run in parallel, but deqp-runner
# doesn't respect that.  We need to extend deqp-runner to allow some tests to be
# marked as single-threaded and run after the rayon loop if we want to support
# them.
#
# Other front-buffer access tests like fbo-sys-blit, fbo-sys-sub-blit, or
# fcc-front-buffer-distraction don't appear here, because the DRI3 fake-front
# handling should be holding the pixels drawn by the test even if we happen to fail
# GL's window system pixel occlusion test.
#
# Note that glx skips don't appear here, they're in all-skips.txt (in case someone
# sets PIGLIT_PLATFORM=gbm to mostly use gbm, but still has an X server running).

ci/piglit: Add some common piglit skips for Mesa CI's testing of glx. Since our X servers don't have a compositor, and we run tests in parallel, various swap and frontbuffer tests won't ever be stable. Rather than having every driver have to track those flakes, make a general X11 skips list as a known issue of our CI rather than pointing fingers at drivers.
