Make microtime properly monotonic, with code derived from the /alpha
...
implementation.

Initialise boot_args and boot_file, for get_bootconf_option().
2001-05-13 13:48:11 +00:00
73bc600e40
Use _LOCORE to recognize assembler in the kernel, not ASSEMBLER (which doesn't

get set).
2001-05-13 13:47:23 +00:00
2af5062ab7
Add <machine/bootconfig.h> on arm26, and add an <arm/bootconfig.h> for it to

include (since all the contents are MI).

Use pool_init() rather than pool_create().
2001-05-09 23:20:59 +00:00

Implement pmap_resident_count() and pmap_wired_count() properly.
2001-05-05 14:20:05 +00:00
8afb876f73
Make the common <arm/profile.h> work on arm26 and arm32, choosing whether
...
to munge R15 or not at runtime. Also make it work with both ELF and a.out.
2001-05-04 00:11:15 +00:00
4928854ae3
Arrange to inline hardsplx() into raisespl() and lowerspl(). This should
...
make them slightly faster, and makes it easier to see how much of the time
apparently spent in hardsplx() actually comes from deferred statclock
interrupts.
2001-05-01 22:19:09 +00:00
c7d1f1542c
Use the correct condition code when deciding whether to take an AST (oops!).
...
Also disable interrupts correctly in the APCS-32 case.

Per discussion w/ chuck and chuck, restructure the md page stuff
...
to use a structure called "vm_page_md", and use __HAVE_VM_PAGE_MD
and __HAVE_PMAP_PHYSSEG.
2001-05-01 02:19:13 +00:00
a6b4c8d3da
Strip the PSR bits off values of R15 before passing them to _mcount(). This
...
makes call-graph profiling actually work (hooray!).
2001-04-30 23:41:11 +00:00
e5b19b546c
Add two functions, int_off_save() and int_restore(), for mcount to use to
...
disable interrupts without getting into a loop or screwing up irq_handler().
Also use them.
2001-04-30 19:57:10 +00:00
2b27ac7a99
Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for
...
each vm_page structure. Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM. These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.
This deprecates struct pmap_physseg. As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.
Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now). Changes to other pmap
modules will follow.
2001-04-29 22:44:31 +00:00
45eb40e8d3
Minimal implementation of cpu_sysctl().
2001-04-29 15:13:45 +00:00

Add ipfilter, rnd, vcoda and raid.
2001-04-28 17:41:01 +00:00
271fb855ce
Arrange to restore R14 on return from __mcount, so that profiled assembler
...
routines will work. We could put this in _PROF_PROLOGUE, but this seems
lighter-weight and possibly cleaner.
2001-04-26 22:09:57 +00:00
a60e816e7a
Provide a pmap_resident_count() that simply expands to 0.
2001-04-25 18:03:19 +00:00

Undo my accidental revival of pmap_kenter_pgs().
2001-04-25 16:30:03 +00:00
7cf0a5e592
Arrange the "unamanaged" pages (entered through pmap_kenter_pa()) are tracked
...
and ignored as necessary.
2001-04-25 14:42:31 +00:00
05d087e7c7
Remove definitions of CLKF_*. They're defined in <arm/cpu.h> now.
2001-04-24 18:15:44 +00:00
1c3a62e066
Sprinkle pmap_update() calls after calls to:
...
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).
These calls are relatively conservative. It may be possible to
optimize these a little more.
2001-04-24 04:30:50 +00:00
55044638aa
Remove pmap_kenter_pgs(). It was never really adopted by
...
anything, and the interface itself wasn't as flexible as
callers would have probably liked.
2001-04-22 23:42:11 +00:00
ec66f67f3a
Use pmap_kenter_pa() rather than pmap_kenter_pgs().
2001-04-22 23:28:52 +00:00

Undo a misguided previous change to the pmap_update() API.
2001-04-22 23:19:26 +00:00
5871b80f00
Use uvm_pageboot_alloc() for early memory allocation, rather than
...
calling pmap_steal_memory() directly. On these platforms, since
uvm_pageboot_alloc() is a wrapper around pmap_steal_memory(), there
is no functional change. This is merely for API consistency.
2001-04-22 18:21:48 +00:00
cfb5c7ed9f
Make pmap_virtual_space() a required pmap function, even on platforms
...
which have pmap_steal_memory(). This is to reduce the API differences
between pmaps that implement pmap_steal_memory() and pmaps which do
not.
Note that pmap_steal_memory() needs to adjust *vstartp and/or
*vendp only if it used addresses within the range provided to UVM
via the pmap_virtual_space() call. I.e. it is not necessary to do
so in any current pmap_steal_memory() implementation.

Add a skeleton driver for the random latches on the Archimedes, which are
