davidxu	e034ab54f2	Check environment variable PTHREAD_ADAPTIVE_SPIN, if it is set, use ... it as a default spin cycle count.	2006-12-20 04:43:34 +00:00
davidxu	26cbb63b3f	Create inline function _thr_umutex_trylock2 to only try one atomic ... operation, if it is failed, we call syscall directly, this saves one atomic operation per lock contention.	2006-12-14 13:22:02 +00:00
davidxu	f1f5293365	Add _thr_ucond_init().	2006-12-05 06:53:44 +00:00
davidxu	cbb0fd8174	Use kernel provided userspace condition variable to implement pthread ... condition variable.	2006-12-04 14:20:41 +00:00
davidxu	653013bedc	o Make _thr_umutex_init a function. ... o Eliminate unused parameter for some functions. o Convert type of first parameter to void * for _thr_umtx_wait and _thr_umtx_wake.	2006-10-13 22:31:00 +00:00
davidxu	21e4536026	Replace internal usage of struct umtx with umutex which can supports ... real-time if we want, no functionality is changed.	2006-09-06 04:04:10 +00:00
davidxu	77e7cda2cf	Add umutex APIs.	2006-08-28 04:47:27 +00:00

davidxu	dc3be45bb9	Cast to uintptr_t to avoid compiler warning, it was broken by ... the recent atomic_ptr() change.	2005-07-28 03:34:54 +00:00
davidxu	f066519e91	Import my recent 1:1 threading working. some features improved includes: ... 1. fast simple type mutex. 2. __thread tls works. 3. asynchronous cancellation works ( using signal ). 4. thread synchronization is fully based on umtx, mainly, condition variable and other synchronization objects were rewritten by using umtx directly. those objects can be shared between processes via shared memory, it has to change ABI which does not happen yet. 5. default stack size is increased to 1M on 32 bits platform, 2M for 64 bits platform. As the result, some mysql super-smack benchmarks show performance is improved massivly. Okayed by: jeff, mtm, rwatson, scottl	2005-04-02 01:20:00 +00:00
