* u_queue: add a futex-based implementation of fencesNicolai Hähnle2017-11-091-0/+92
| | | | | | | | | | | | | | | | | Fences are now 4 bytes instead of 96 bytes (on my 64-bit system). Signaling a fence is a single atomic operation in the fast case plus a syscall in the slow case. Testing if a fence is signaled is the same as before (a simple comparison), but waiting on a fence is now no more expensive than just testing it in the fast (already signaled) case. v2: - style fixes - use p_atomic_xxx macros with the right barriers Acked-by: Marek Olšák <[email protected]>

* util/u_queue: add an option to resize the queue when it's fullMarek Olšák2017-07-171-0/+2
| | | | | | | | | | | | | | | | | | | | Consider the following situation: mtx_lock(mutex); do_something(); util_queue_add_job(...); mtx_unlock(mutex); If the queue is full, util_queue_add_job will wait for a free slot. If the job which is currently being executed tries to lock the mutex, it will be stuck forever, because util_queue_add_job is stuck. The deadlock can be trivially resolved by increasing the queue size (reallocating the queue) in util_queue_add_job if the queue is full. Then util_queue_add_job becomes wait-free. radeonsi will use it. Reviewed-by: Nicolai Hähnle <[email protected]>
* mesa/glthread: add glthread "perf" counters and pass them to gallium HUDMarek Olšák2017-06-261-0/+14
| | | | | | | | | | | for HUD integration in following commits. This valuable profiling data will allow us to see on the HUD how well glthread is able to utilize parallelism. This is better than benchmarking, because you can see exactly what's happening and you don't have to be CPU-bound. u_threaded_context has the same counters.

This will allow us to use it outside of gallium for things like compressing shader cache entries. Reviewed-by: Marek Olšák <[email protected]>
