Add support for some environment variables in deqp-runner on Windows
Add support for $DEQP_FRACTION
, $CI_NODE_TOTAL
, $FDO_CI_CONCURRENT
, $DEQP_WIDTH
, $DEQP_HEIGHT
, $DEQP_SURFACE_TYPE
and $DEQP_CONFIG
.
Also clean up the deqp-runner-run.ps1
script to be clearer and add some tests to the flakes list as they seem to sometimes fail..
