* Repo copy libpthreads to libkse.David E. O'Brien2007-10-0937-3968/+0
| | | | | | | | | This introduces the WITHOUT_LIBKSE nob, and changes WITHOUT_LIBPTHREADS to mean with neither threading libs. Approved by: re(kensmith) Notes: svn path=/head/; revision=172492
* Stylize:Marcel Moolenaar2006-09-012-35/+51
| | | | | | | | | | o avoid using a global register variable. o redefine struct ia64_tp as a union. We don't have to get to the fields themselves. We just need it to be of the right size with the right alignment. Notes: svn path=/head/; revision=161841
* The ucontext is 16-byte aligned, which means that struct tcb isMarcel Moolenaar2006-09-011-0/+1
| | | | | | | | | | 16-byte aligned. Consequently, struct tcb is a multiple of 16 bytes in size. We need to make sure there's no padding after struct ppc32_tp. We do this by explicitly adding the necessary padding in front of it. Notes: svn path=/head/; revision=161830
* Stylize. Introduce ppc_{get|set}_tp() and ppc_{get|set}_tcb() toMarcel Moolenaar2006-09-012-29/+59

* Clean out the leftovers from the i386_set_gsbase() TLS conversion.Peter Wemm2005-06-292-51/+8
| | | | | | | | | | | Like on libthr, there is an i386_set_gsbase() stub implementation here to avoid libc.so.5 issues. This should likely be a weak symbol and I expect this will be fixed soon. Approved by: re Notes: svn path=/head/; revision=147673
* Add a missing END() to quiet a warning.John Baldwin2005-05-311-0/+1

| | | | | | | | that the amd64 kernel implements i386_get/set_gsbase(). All the rest of the ldt backwards compat code should go away soon. Notes: svn path=/head/; revision=145569
* Use the i386_set_gsbase() syscall if it is implemented in the kernel.Peter Wemm2005-04-142-16/+41
| | | | | | | | This is a little hairy here because the allocation and usage of this functionality is split into two places in libpthread. Notes: svn path=/head/; revision=145039

| | | | | | | | | | | These files had tags after teh copyright notice, inside the comment block (incorrect, removed), and outside the comment block (correct). Approved by: rwatson (mentor) Notes: svn path=/head/; revision=125669
* Simplify the contexts created by the kernel and remove the relatedMarcel Moolenaar2003-12-071-0/+6
| | | | | | | | | | | | flags. We now create asynchronous contexts or syscall contexts only. Syscall contexts differ from the minimal ABI dictated contexts by having the scratch registers saved and restored because that's where we keep the syscall arguments and syscall return values. Since this change affects KSE, have it use kse_switchin(2) for the "new" syscall context. Notes: svn path=/head/; revision=123255
* Apply a second fix for stack alignment with libkse. This time, enter thePeter Wemm2003-12-051-2/+2
| | | | | | | | | | | | | | UTS with the stack correctly aligned. Also, while here, use an indirect jump rather than the pushq/ret hack. This fixes threaded apps that use floating point for me, although it hasn't solved all the problems. It is an improvement though. Preservation of the 128 byte red zone hasn't been resolved yet.

* Update context code for my last ABI breakage of mcontext. I'm worriedPeter Wemm2003-10-171-7/+8
| | | | | | | | | | about the fpu code here. It should be using fxsave/fxrstor instead of saving/restoring the control word. The SSE registers are used a lot in gcc generated code on amd64. I'm not sure how this all fits together though. Notes: svn path=/head/; revision=121163

* Make KSE_STACKSIZE machine dependent by moving it from thr_kern.c toMarcel Moolenaar2003-09-194-1/+8
| | | | | | | | | pthread_md.h. This commit only moves the definition; it does not change it for any of the platforms. This more easily allows 64-bit architectures (in particular) to pick a slightly larger stack size. Notes: svn path=/head/; revision=120263
* _ia64_break_setcontext() now takes a mcontext_t. While here, defineMarcel Moolenaar2003-09-191-10/+3
| | | | | | | | | | | | | | | THR_SETCONTEXT as PANIC(). The THR_SETCONTEXT macro is currently not used, which means that the definition we had could be wrong, overly pessimistic or unknowingly right. I don't like the odds... The new _ia64_break_setcontext() and corresponding kernel fixes make KSE mostly usable. There's still a case where we don't properly restore a context and end up with a NaT consumption fault (typically an indication for not handling NaT collection points correctly), but at least now mutex_d works...
