[Mesa-dev] [PATCH v4 1/1] clover: Wait for requested operation if blocking flag is set

[Jan Vesely]

v2: wait in map_buffer and map_image as well
v3: use event::wait instead of wait (skips fence wait for hard_event)
v4: use wait_signalled()

Hi Francisco,

once again sorry for the delay, and thanks for you patience.
This patch applies on top of the two you attached during our email
discussion.
>From what I can tell, the functionality is identical to v3 after your
two patches are applied ("event:wait()" calls "wait_signalled()"), but I
suppose calling non-virtual function is preferrable. if not, feel free
to use v3.

thanks,
Jan
