- atomic_add & atomic_cmpxchg added to ppc - atomic_unkown (used when the procesor does not suport atomic ops or is not among the supported ones), tries now to use a "hash" of locks if GEN_LOCK_SET_T_UNLIMITED is defined => less contention on multi-cpus - atomic_ops.h defines *_UNLIMITED macros when the number of locks or set size are limited only by the available memory (everything exept SYSV sems) - license changes: all the atomic* stuff and the locks are now under a BSD (OpenBSD) style licenseAndrei Pelinescu-Onciul authored on 11/05/2007 20:44:15 |

- fastlock: optimizations (in general a "nicer" spin on the lock for the other cpus) and cleanups for sparc, sparc64, armv6 (nosmp for now), ppc*, mips* - fastlock: alpha: replace the cond. jump backward with a cond. jump forward and then jump backward (because a cond. jump with a negative relative offset is always predicted as taken and we want it to be predicted as not taken) - fastlock: sparc (32) smp support - lock_ops.h: introduced lock_try and lock_set_try (non-blocking lock_*_get versions, returns -1 if it failed to get the lock and 0 if it succeeds), for all the supported locking methods (fast_lock, pthread_mutex, posix_sem, sysv_sems) - updated locking doc.Andrei Pelinescu-Onciul authored on 04/04/2006 18:04:01 |

- lock optimizations: use the lock specific membar only if the lock_get operation succeeded (this means don't use it while spinning) => move the membar call in get_lock or try_lockAndrei Pelinescu-Onciul authored on 03/04/2006 14:30:51 |

- added mb_atomic_* ops, equivalent to membar(); atomic_*, but more optimized (e.g. on x86 most atomic ops act also as memory barriers so mb_atomic_* will be equiv. to atomic_* )Andrei Pelinescu-Onciul authored on 15/03/2006 19:16:39 |
