* Add a special page zero entry point intended to be called via the singlePeter Wemm2002-07-081-0/+15
| | | | | | | | | | | | | | | | | | threaded VM pagezero kthread outside of Giant. For some platforms, this is really easy since it can just use the direct mapped region. For others, IPI sending is involved or there are other issues, so grab Giant when needed. We still have preemption issues to deal with, but Alan Cox has an interesting suggestion on how to minimize the problem on x86. Use Luigi's hack for preserving the (lack of) priority. Turn the idle zeroing back on since it can now actually do something useful outside of Giant in many cases. Notes: svn path=/head/; revision=99571
* Collect all the (now equivalent) pmap_new_proc/pmap_dispose_proc/Peter Wemm2002-07-071-154/+0
| | | | | | | | | | | | | | | | pmap_swapin_proc/pmap_swapout_proc functions from the MD pmap code and use a single equivalent MI version. There are other cleanups needed still. While here, use the UMA zone hooks to keep a cache of preinitialized proc structures handy, just like the thread system does. This eliminates one dependency on 'struct proc' being persistent even after being freed. There are some comments about things that can be factored out into ctor/dtor functions if it is worth it. For now they are mostly just doing statistics to get a feel of how it is working. Notes: svn path=/head/; revision=99559

* Squish the "could sleep with process lock" messages caused by callingAlfred Perlstein2002-06-191-2/+6
| | | | | | | | | | | | | | | | | | | | | | | uifind() with a proc lock held. change_ruid() and change_euid() have been modified to take a uidinfo structure which will be pre-allocated by callers, they will then call uihold() on the uidinfo structure so that the caller's logic is simplified. This allows one to call uifind() before locking the proc struct and thereby avoid a potential blocking allocation with the proc lock held. This may need revisiting, perhaps keeping a spare uidinfo allocated per process to handle this situation or re-examining if the proc lock needs to be held over the entire operation of changing real or effective user id.

* - Fixup / remove obsolete comments.John Baldwin2002-06-071-16/+12
| | | | | | | | | | | | | | - ktrace no longer requires Giant so do ktrace syscall events before and after acquiring and releasing Giant, respectively. - For i386, ia32 syscalls on ia64, powerpc, and sparc64, get rid of the goto bad hack and instead use the model on ia64 and alpha were we skip the actual syscall invocation if error != 0. This fixes a bug where if we the copyin() of the arguments failed for a syscall that was not marked MP safe, we would try to release Giant when we had not acquired it.

The elf_lookup() function operates on the symbol index and will do a symbol name based lookup when such is required, otherwise it uses the symbol index directly. This solves the problem seen on ia64 where the symbol hash table does not contain local symbols and a symbol name based lookup would fail for those symbols. Don't pass the symbol name to elf_reloc(), as it isn't used any more. Notes: svn path=/head/; revision=95410
