[PATCH i-g-t 2/3] i915/gem_exec_fence: Allow GPU resets during hang checks

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

 



The pair of *-hang-all will generate sufficient hangs for the kernel to
ban the client. This is unfortunate as it means all further tests are
skipped. Ask nicely not to be banned.
