Warner Losh 35e58ed326 Remove commented out PCI_ENABLE_IO_MODES. It is gone now. 2002-08-04 18:06:15 +00:00
Jeff Roberson e6e370a7fe - Replace v_flag with v_iflag and v_vflag 
- v_vflag is protected by the vnode lock and is used when synchronization
   with VOP calls is needed.
 - v_iflag is protected by interlock and is used for dealing with vnode
   management issues.  These flags include X/O LOCK, FREE, DOOMED, etc.
 - All accesses to v_iflag and v_vflag have either been locked or marked with
   mp_fixme's.
 - Many ASSERT_VOP_LOCKED calls have been added where the locking was not
   clear.
 - Many functions in vfs_subr.c were restructured to provide for stronger
   locking.

Alan Cox 5da2d6a46d o Don't set PG_MAPPED on the page allocated and mapped in _pmap_allocpte(). 
(Only set this flag if the mapping has a corresponding pv list entry,
   which this mapping doesn't.)

Peter Wemm 8f1586dd65 Take advantage of the fact that there is a small 1MB direct mapped region 
on x86 in between KERNBASE and the kernel load address.  pmap_mapdev()
can return pointers to this for devices operating in the isa "hole".

Peter Wemm 1af04fadd1 Take a shot at fixing a nasty bug in the pmap changes that I did. I 
missed the pmap_kenter/kremove in this file, which leads to read()/write()
of /dev/mem using stale TLB entries. (gah!)  Fortunately, mmap of /dev/mem
wasn't affected, so it wasn't as bad as it could have been.  This throws
some light on the 'X server affects stability' thread....

Alan Cox 239b5b9707 o Setting PG_MAPPED and PG_WRITEABLE on pages that are mapped and unmapped 
by pmap_qenter() and pmap_qremove() is pointless.  In fact, it probably
   leads to unnecessary pmap_page_protect() calls if one of these pages is
   paged out after unwiring.

Note: setting PG_MAPPED asserts that the page's pv list may be
non-empty.  Since checking the status of the page's pv list isn't any
harder than checking this flag, the flag should probably be eliminated.
Alternatively, PG_MAPPED could be set by pmap_enter() exclusively
rather than various places throughout the kernel.

Mike Barcroft 49545b3891 Create a new header <machine/_stdint.h> for storing MD parts of 
<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>.

Peter Wemm 3ebc124838 Infrastructure tweaks to allow having both an Elf32 and an Elf64 executable 
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).

Poul-Henning Kamp 3ae87b7ec6 Add an entry for the AMD Elan SC520 hostbridge. I do not belive we can

precense of the on-chip host to PCI bridge.
