* Add syscalls thr_setscheduler, thr_getscheduler, and thr_setschedparam,David Xu2006-07-131-2/+9
| | | | | | | | | | | these syscalls are designed to set thread's scheduling parameters and policy, because each syscall contains a size parameter, it is possible to support future scheduling option, e.g SCHED_SPORADIC, this option needs other fields in structure sched_param, current they are not avaiblable.

* Close a race between a thread exiting and the freeing of it's stack.Mike Makonnen2004-10-061-1/+1
| | | | | | | | | | | | After some discussion the best option seems to be to signal the thread's death from within the kernel. This requires that thr_exit() take an argument. Discussed with: davidxu, deischen, marcel MFC after: 3 days Notes: svn path=/head/; revision=136192
* Change the thread ID (thr_id_t) used for 1:1 threading from being aMarcel Moolenaar2004-07-021-9/+4
| | | | | | | | | | | | | | | | | | | | | | | pointer to the corresponding struct thread to the thread ID (lwpid_t) assigned to that thread. The primary reason for this change is that libthr now internally uses the same ID as the debugger and the kernel when referencing to a kernel thread. This allows us to implement the support for debugging without additional translations and/or mappings. To preserve the ABI, the 1:1 threading syscalls, including the umtx locking API have not been changed to work on a lwpid_t. Instead the 1:1 threading syscalls operate on long and the umtx locking API has not been changed except for the contested bit. Previously this was the least significant bit. Now it's the most significant bit. Since the contested bit should not be tested by userland, this change is not expected to be visible. Just to be sure, UMTX_CONTESTED has been removed from <sys/umtx.h>. Reviewed by: mtm@ ABI preservation tested on: i386, ia64 Notes: svn path=/head/; revision=131431
