skrll 0b99767bfe Remove unnecessary include. 2008-08-11 21:45:24 +00:00
matt 2b0c4dcffd Change pthread_mutex_t to use the amount of space as and be congruent to 
the version used in the SA version of pthreads.  This preserves binary
compatibility between both versions of the library.

gmcgarry 5aa0bc7608 Selector registers are 16-bit and binutils 2.18 insists that only 16-bit 
accesses are permitted on them.  Therefore, change movl to movw.  No change to
machine code generated.

rmind e6acd90e07 - Add affinity(3) manual page, which describes thread affinity, 
pthread_setaffinity_np(3) and pthread_getaffinity_np(3) functions,
  provides simple code example.
- Add cpuset(3) manual page, which describes API of CPU-sets.

Thanks <wiz> for many improvements!

uwe c39ae7f5d7 Recycle unused _REG_EXPEVT slot in mcontext for _REG_GBR. 
As the size of mcontext is not changed, we avoid the hassle of
versioning all the calls that use it.

_REG_EXPEVT was never used by any code in the tree.  Reporting EXPEVT
makes sense only for signals and in that case we pass it to userland
in ksi_trap already which is official MI way to get this (MD) information.

Old binaries running on new kernels will now have their GBR set from
new mcontext, but that's ok too, as GBR was not properly supported by
old kernels (not saved in trapframe), so old binaries couldn't have
possibly used it anyway.

ad c4612ba227 More blurb about the mutex and limitations. 2008-05-26 02:25:05 +00:00
ad 3ad4fb5234 Note that when calling pthread_cond_broadcast/signal, the same mutex as 
passed to wait/timedwait must be held.

ad 9d566f8240 Note that apps with real-time threads shouldn't use spinlocks because of 
the danger of deadlock, and note that in general spinlocks suck and mutexes
should be used instead!

ad 2bcb8bf1c4 PR lib/38741 priority inversion in libpthread breaks apps that use 
SCHED_FIFO threads

- Change condvar sync so that we never take the condvar's spinlock without
  first holding the caller-provided mutex. Previously, the spinlock was only
  taken without the mutex in an error path, but it was enough to trigger the
  problem described in the PR.

- Even with this change, applications calling pthread_cond_signal/broadcast
  without holding the interlocking mutex are still subject to the problem
  described in the PR. POSIX discourages this saying that it leads to
  undefined scheduling behaviour, which seems good enough for the time being.

- Elsewhere, use a hash of mutexes instead of per-object spinlocks to
  synchronize entry/exit from sleep queues.

- Simplify how sleep queues are maintained.
