[PATCH v3 0/6] dma-buf: Check status of enable-signaling bit on debug

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

 



Fence signaling must be enabled to make sure that
the dma_fence_is_signaled() function ever returns true.
Since drivers and implementations sometimes mess this up,
this ensures correct behaviour when DEBUG_WW_MUTEX_SLOWPATH
is used during debugging.
This should make any implementation bugs resulting in not
signaled fences much more obvious.
