[PATCH 1/1] drm/radeon: check return vlaue of radeon_fence_emit

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

 



From: Pan Bian <bianpan2016@xxxxxxx>

Function radeon_fence_emit() returns -ENOMEM if there is no enough
memory. And in this case, function radeon_ring_unlock_undo() rather than
function radeon_ring_unlock_commit() should be called. However, in
function radeon_test_create_and_emit_fence(), the return value of
radeon_fence_emit() is ignored. This patch adds the check.
