e4892d7157 When invaliding single icache line on XScale, the branch target buffer 
also needs to be invalidated.  Also, but in the right sequence to empty
the pipeline on XScale.

ed5e27cc44 Increase the size of a jmp_buf when using ELF, since this will be our last 
chance to do so for a while.  We don't use the extra space yet, but VFP
support is likely to need it.

140252be2b Arm has a vac, so we must use pmap_enter/remove for vmapbuf rather than k* versions, otherwise we may not be doing the right caching thing. 2001-08-20 21:52:09 +00:00

4bc8190b62 Change local offset/label for irqhandlers to Lirqhandlers. Because in 
ELF _C_LABEL(irqhandlers) == irqhandlers so we were getting self-referential
pointer which causes the IRQ to fall on itself.  [With this change the
netwinder kernel can now be *ELF* and boots to multiuser]

c495131fe3 Move _insque()/_remque() to libkern. Once remaining uses would 
be converted to <sys/queue.h> macros, _insque()/_remque() would be eliminated
altogether.

191de4d242 Checking a whole host of pmap changes: 
Improved locking (not that we actually use it on a uniprocessor, but one day :)
Removed unneeded splvm's
tweaked pmap_clean_page code to only flush the cache if the page is mapped in the current pmap  (based on diff from richard E)
Adopted pv entry allocation mechanism from i386.
Laid framework for returning ptp's when we've finished with them rather than holding onto them till the process exits.
ptp's are now allocated with a uvm object for the pmap, means that we can walk a list to free them off in pmap_release, until they get freed off by pmap_remove.

Also implemented a page zeroing function when the processor is idling.  Note that hpcarm may wish to disable this.

I believe this code to be stable, if anyone has any problems please shout up.

6e43d02452 Patch in Richard E's changes to bcopy page, the loop doesn't need unrolling as much as it currently is due to the overhead of the load/stores taking most of the time. (profiling shows minimal time difference) 2001-08-11 12:44:42 +00:00

fa4e4d9668 Rework the pmap_release code to not have to walk the ptpt, it now uses a uvm_object to track the allocated vm_pages, this means it can free off the entries in the uvm_object. 
Testing shows that it's about 5% faster on the make configure step for gmake.

9f04d8d670 A couple of tidy ups to pmap: 
pmap_t -> struct pmap * in pmap.c and pmap.h
kernel_pmap -> pmap_kernel() everywhere.
