[PATCH i-g-t] lib: Restore i915.reset before testing it in igt_allow_hang()

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

 



igt_allow_hang() checks that the GPU can be reset before allowing the
test to cause a GPU hang (which would need the reset to recover).
However, our checking for allowing a hang depends on i915.reset which we
later restore. Do that restoration before the check so that this test is
not affected by earlier fails.
