* Implement and document nan(), nanf(), and nanl(). This commitDavid Schultz2007-12-161-4/+23
| | | | | | | | | | adds two new directories in msun: ld80 and ld128. These are for long double functions specific to the 80-bit long double format used on x86-derived architectures, and the 128-bit format used on sparc64, respectively. Notes: svn path=/head/; revision=174684

For example, getgrouplist(3) will use module-supplied 'getgroupmembership' function (which can work in an optimal way for such source as LDAP) and will fall back to the stanard iterate-through-all-groups implementation otherwise.

* | Implement dynamic load balancing of thread-->arena mapping, based on lockJason Evans2007-11-271-58/+297
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | contention. The intent is to dynamically adjust to load imbalances, which can cause severe contention. Use pthread mutexes where possible instead of libc "spinlocks" (they aren't actually spin locks). Conceptually, this change is meant only to support the dynamic load balancing code by enabling the use of spin locks, but it has the added apparent benefit of substantially improving performance due to reduced context switches when there is moderate arena lock contention. Proper tuning parameter configuration for this change is a finicky business, and it is very much machine-dependent. One seemingly promising solution would be to run a tuning program during operating system installation that computes appropriate settings for load balancing. (The pthreads adaptive spin locks should probably be similarly tuned.) Notes: svn path=/head/; revision=173968
* | Implement lazy deallocation of small objects. For each arena, maintain aJason Evans2007-11-271-0/+218
| | | | | | | | | | | | | | | | | | | | | | | | | | | | vector of slots for lazily freed objects. For each deallocation, before doing the hard work of locking the arena and deallocating, try several times to randomly insert the object into the vector using atomic operations. This approach is particularly effective at reducing contention for multi-threaded applications that use the producer-consumer model, wherein one producer thread allocates objects, then multiple consumer threads deallocate those objects.

The kldstat(2) API is versioned with the size of the kld_file_stat structure, so this change creates version 2. Add the pathname to the verbose output of kldstat(8) too.
