* util: move process.[ch] to u_process.[ch]Dylan Baker2018-08-011-1/+1
| | | | | | | | | | | | | On windows process.h is a system provided header, and it's required in include/c11/threads_win32.h. This header interferes with searching for that header, and results in windows build warnings with scons, but errors in meson which doesn't allow implicit function declarations. Just rename process to u_process, which follows the style of utils anyway.

* u_queue: add a futex-based implementation of fencesNicolai Hähnle2017-11-091-0/+2
| | | | | | | | | | | | | | | | | 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/queue: fix a race condition in the fence codeNicolai Hähnle2017-09-291-0/+13
| | | | | | | | | | | | | | | | A tempting alternative fix would be adding a lock/unlock pair in util_queue_fence_is_signalled. However, that wouldn't actually improve anything in the semantics of util_queue_fence_is_signalled, while making that test much more heavy-weight. So this lock/unlock pair in util_queue_fence_destroy for "flushing out" other threads that may still be in util_queue_fence_signal looks like the better fix. v2: rephrase the comment Cc: [email protected] Reviewed-by: Marek Olšák <[email protected]> Reviewed-by: Gustaw Smolarczyk <[email protected]>

* util/u_queue: add an option to resize the queue when it's fullMarek Olšák2017-07-171-3/+34
| | | | | | | | | | | | | | | | | | | | 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]>

* util/queue: don't hang at exitRob Clark2017-04-181-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So atexit() is horrible and 4aea8fe7 is probably not a good idea. But add an extra layer of duct-tape to the problem. Otherwise we hit a situation where app using an atexit() handler that runs later than ours doesn't hang when trying to tear down a context.
