| | | | | | | | | <stdint.h>. Previously, parts were defined in <machine/ansi.h> and <machine/limits.h>. This resulted in two problems: (1) Defining macros in <machine/ansi.h> gets in the way of that header only defining types. (2) Defining C99 limits in <machine/limits.h> adds pollution to <limits.h>.

| | | | | | | | | | | | | | | handler in the kernel at the same time. Also, allow for the exec_new_vmspace() code to build a different sized vmspace depending on the executable environment. This is a big help for execing i386 binaries on ia64. The ELF exec code grows the ability to map partial pages when there is a page size difference, eg: emulating 4K pages on 8K or 16K hardware pages. Flesh out the i386 emulation support for ia64. At this point, the only binary that I know of that fails is cvsup, because the cvsup runtime tries to execute code in pages not marked executable. Obtained from: dfr (mostly, many tweaks from me).

The machine that I have has 4 cpus and a very big hole in the middle. This makes the bogus '(last_address - first_address) / PAGE_SIZE' calculations especially dangerous and caused many millions of initial PV/PTE's to be preallocated.

* Add a special page zero entry point intended to be called via the singlepeter2002-07-081-0/+16
| | | | | | | | | | | | | | | 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.
* Collect all the (now equivalent) pmap_new_proc/pmap_dispose_proc/peter2002-07-071-148/+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.
* Back out proc part of last commit. UMA manages the thread cache only, andpeter2002-07-051-8/+22
| | | | | | | | | we just have to deal with the kstack when told to. We do not have a UMA-managed cache for the proc struct and its associated upage yet. So, go back to the old lazy mechanism. Note that if UMA destroys pages that used to contain proc structures, we'll lose the corresponding upage forever. (zones never did this - once a page was allocated, it stayed attached to the proc zone forever)

Otherwise if another unrelated process gets the exact same vmspace structure allocated to it (same address), its address space will not be activated properly. This seems to fix some spontaneous signal 11 problems with smp on sparc64.

| | | | | | | | | | | - 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.
