Optimize the run queue frobnication, and add some more DIAGNOSTIC checks.
1994-09-09 02:56:54 +00:00

Another tiny optimization.

Add a simple pv_page garbage collector (currently disabled).

4116a4243e
Various changes:
...
* Inline some functions.
* Eliminate redundant calls to pmap_page_index().
* Reduce the number of TLB flushes in accordance with the i386 SSWG.
* Inline pmap_remove() in pmap_remove_all(). (Most if it is unnecessary.)
* Allocate pv_entry's in pages, and keep a list of free entries in each page,
and a list of pages with free entries. (Trying to reduce malloc() overhead,
and improve locality of reference.)
* Remove a couple of macros that aren't really useful.
* Remove pmap_kernel() completely.

vm_object_page_clean() expects to be able to use vm_page_deactivate() on a
...
locked page. Make that work. This also obviates the need for vm_fault() to
bogusly activate a page before deactivating it. Finally, make sure the
semantics of vm_object_deactive_pages() don't change.

Misc changes to make this file more like the asm.h headers used by other
...
architectures:
Renamed _C_FUNC() to _C_LABEL()
Renamed _ASM_FUNC() to _ASM_LABEL()
Merged _BEGIN_ENTRY with _ENTRY
Renamed _END_ENTRY to _PROF_PROLOGUE
When assembling with profiling enabled, set up stack frame before calling
mcount() in _PROF_PROLOGUE. Also omit emitting .long 0's, as they are no
longer used by the profiling code.
