07a1b88ab8 Use the physmem variable to get at the physical memory size (instead of the 
avail_end - avail_start difference which is only correct on machines with
contiguous memory).

9264961c87 add a short delay (5ms) after ATAPI software reset is done, suggested by 
Soren S. Jorvang <soren@t.dk>.  Apparently some devices Really Want this.

db74b327b9 fix a few bogus pointer checks (was checking pointers which would 
never be against NULL, instead of checking the correct pointer against
NULL).  Pointed out (with diff) to Mark Brinicombe on March 17, no reply.

a95651eaea Add a PMAP_KERNEL_PTE() macro that returns the PTE for a given KVA. If 
DEBUG, this performs a table walk.  Othwise, the Virtual Page Table is
used.  Use this macro in a few places where this was done by-hand.

Make vtophys() use PMAP_KERNEL_PTE().  In non-DEBUG cases, this is
a fair bit faster.

3a1500efe9 Per X/Open CAE Spec Issue 5 Version 2, change the buffer size argument of 
readlink() from type `int' to type `size_t'.  This isn't an ABI change, since
the calling convention of our only LP64 platform (the Alpha) already promotes
this argument to a `long'.

This may not be the final action on this matter; readlink() still returns
an `int', which may change in a future revision of the standard.

b436157e65 Make proc0 use the statically-allocate vmspace0 again, and make it use 
the kernel's pmap, since proc0 (and other that share its address space)
are kernel-only processes, and should never contain userspace mappings.

This makes it easier to detect errors, like entering user mappings
for kernel processes, in pmap modules, and makes some sense, considering
that kernel processes are really just "thread contexts" for the kernel.

b1e15c2005 Add some robustness to pmap_alloc_physpage(): Instead of panic'ing if 
we can't get a page, find an inactive pmap and pmap_collect() it,
freeing up a few pages.  Go ahead and die if we can't allocate a page
after 5 tries.

94a783a350 allow use of new wscons code. 1998-03-27 00:07:53 +00:00
cgd
372e996fc3 when deciding whether to use standard system include files or libkern.h, 
check _STANDALONE as well as _KERNEL.  _KERNEL is incorrect for use when
building boot blocks, and it looks like the rest of the code is already
using _STANDALONE for this purpose.

ef8dc9789a don't actually compile any code if building in a _STANDALONE environment 
(e.g. libkern for boot blocks), since profiling support doesn't make
sense there.

b86884a71a Give pmap_collect() some substance: when called, a process is being 
swapped out, so remove all of the physical mappings the process has
in order to free up the page table pages.

Since the pmap module is allowed to "forget" mappings, pmap_collect()
may be called in other situations where the memory situation is desperate,
although it's more likely that the pages will simply be needed again the
next time a process runs.

db81cc9c76 update per-process rusage fault counters (ru_majflt/ru_minflt) under UVM 1998-03-26 21:50:14 +00:00
chuck
3d3a01805a correctly count ru_majflt. the fix pulled in from pr#1397 is incorrect. 
calling vm_pager_get() doesn't count as a "majflt" unless the pager
returns VM_PAGER_OK.  when walking an object chain we can get VM_PAGER_FAIL
(indicating that the requested data does not reside in this object
and we must continue to walk the chain) -- we don't want to count this
as a majflt.

i also added code to count ru_minflt.
