thorpej 11cae42531 Centralize the declaration and clearing of `cold'. 1999-09-17 19:59:35 +00:00
thorpej 3b01d1b872 Rename the machine-dependent autoconfiguration entry point `cpu_configure()',
and rename config_init() to configure() and call cpu_configure() from there.

chs f3a668ed84 eliminate the PMAP_NEW option by making it required for all ports.
ports which previously had no support for PMAP_NEW now implement
the pmap_k* interfaces as wrappers around the non-k versions.

mycroft 9071f9ee14 Add ieee.h. 1999-08-29 18:10:33 +00:00
simonb 3c185af5fd Include <sys/endian.h> after defining whether where are little- or
big-endian.  i386, pc532 and vax still include <machine/byte_swap.h>
and define macros for the {n,h}to{h,n}*() functions.  mips also
defines some endian-independent assembly-code aliases for unaligned
memory accesses.
1999-08-21 05:53:50 +00:00
simonb 06a92524c2 Include <sys/bswap.h> for function prototypes. i386, pc532 and vax
still include <machine/byte_swap.h> and define macros for some of
the bswap*() functions.

chs bb0c381fb9 two changes to prevent the kernel's pmap from being locked recursively
via interrupts:

(1) pmap_map_ptes() and pmap_unmap_ptes() don't need to do anything to
    map the kernel's pmap, since all pmaps contain the kernel's PTPs.
    this fixes interrupt-context calls to pmap_extract().
(2) pmap_kenter_*() and pmap_kremove() no longer adjust the kernel pmap's
    resident and wired counters.

simonb 299578ebd5 Spell "privilege" correctly (correct spelling from Jonathan Stone). 1999-08-16 02:59:22 +00:00
thorpej 28fb7c1eb8 Define cpu_number() as discussed on tech-smp. 1999-08-10 21:08:05 +00:00
thorpej eb20bbc780 Change the semantics of splsoftclock() to be like other spl*() functions,
that is priority is rasied.  Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.

This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).

XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX.  This platforms still have this bug until their
XXX spl*() functions are fixed.
1999-08-05 18:08:08 +00:00
thorpej 51fe928d5e Slight cleanup; do all of the spl*()s with imask[]. 1999-08-04 15:54:28 +00:00
augustss a7cd454b1d It's time to be COMPAT_14. 1999-07-29 10:37:12 +00:00
thorpej 51d09124f9 Fix another locking error: if freeing a PV entry, don't attempt to
free a PV page if the PV entry was associated with the kernel pmap,
since the kernel pmap is locked, and freeing the page will execute
a code path which will attempt to lock it again, resulting in deadlock.
No real loss, since the next time a PV entry is freed, the page will
be freed, too.
1999-07-28 06:54:41 +00:00
thorpej eced87ad87 Fix a locking error: When allocating a PV page for the kernel pmap,
the pmap would be locked, and we would deadlock when mapping the
newly allocate PV page.
1999-07-28 05:37:54 +00:00
thorpej 9d4524778d Slight adjustment to last; move pmap_kenter_pa() to where the other
pmap_k* functions are.
1999-07-28 01:17:01 +00:00
thorpej 31fa5c6f78 Don't inline pmap_kenter_pa(). It doesn't buy us much to do so, and
it's nice to have it show up in stack traces.
1999-07-28 01:07:52 +00:00
cgd f886376518 be more efficient when doing the SYSTEM_LD_TAIL for -g kernels: don't
copy them just to strip them, use strip -o.

chs 47602880d7 KNF. 1999-07-18 21:33:20 +00:00
thorpej 0945bf58b0 Add examples for including the kernel crypto bits from either crypto-us
or crypto-intl, commented out, with instructions to use only one, and
adjust the prefix as necessary.
1999-07-09 18:55:33 +00:00
mrg ecdad0ec33 clean up a bit after jason :)
- fix emitrules() like emitfiles() to deal with the prefix (otherwise it
  would attempt to find the file in the normal base for the NORMAL_C rule).
- add emitincludes() which adds include directives for each prefix to the
  $INCLUDES variable in the makefile.
- add %INCLUDES to each Makefile.arch to deal with the above.

this makes "prefix" actually work in a usable manner, and now i can move
on to fixing compiler warnings (errors) in the ESP code. :)

thorpej b2781586c4 Normalize include paths. 1999-07-09 02:32:28 +00:00
thorpej 3ebbe095e0 Change the pmap_extract() interface to:
boolean_t pmap_extract(pmap_t, vaddr_t, paddr_t *);
This makes it possible for the pmap to map physical address 0.

itojun 5effafcaa6 kernel configuration for IPv6/IPsec. should be in GENERIC in the future.
(source code will be committed soon)
1999-07-01 07:00:12 +00:00
itojun 427639cdce - Call ip6intr if INET6 is defined.
- remove "need-flag" for mac68k esp driver, as it is not used in anywhere
  and conflicts with IPsec ESP header.

This should be the only MD change in IPv6 support, except kernel config file.
Very sorry if you have any compilation problem with it (I believe it is okay).
If your favorite arch is not included in here, please add a
call to ip6intr() from softintr handle.

thorpej 0288ffb53a pmap_change_wiring() -> pmap_unwire(). 1999-06-17 19:23:20 +00:00
thorpej f5a527bb4e Remove pmap_pageable(); no pmap implements it, and it is not really useful,
because pmap_enter()/pmap_change_wiring() (soon to be pmap_unwire())
communicate the information in greater detail.
1999-06-17 18:21:21 +00:00
thorpej f51688dd8b PMAP_NEW is no longer optional on the pc532; the old pmap's page table
allocation strategy no longer works at all.  Move pmap.new.* to pmap.*.

To read the revision history of PMAP_NEW up until this merge, use cvs
rlog of the old pmap.new.* files.

thorpej d76e7b8c6d Don't pass a nam2blk around at all; just have setroot() and friends reference
dev_name2blk[] directly.  Addresses PR #7622 (ITOH Yasufumi), although
in a different way.

thorpej a2d06a4721 Generally update the comment above the vmapbuf() implementations. 1999-05-26 22:07:36 +00:00
thorpej 2580d306ab Change the vm_map's "entries_pageable" member to a r/o flags member, which
has PAGEABLE and INTRSAFE flags.  PAGEABLE now really means "pageable",
not "allocate vm_map_entry's from non-static pool", so update all map
creations to reflect that.  INTRSAFE maps are maps that are used in
interrupt context (e.g. kmem_map, mb_map), and thus use the static
map entry pool (XXX as does kernel_map, for now).  This will eventually
change now these maps are locked, as well.

thorpej 5b897f96c5 msgbuf doesn't need VM_PROT_EXEC. 1999-05-25 23:31:14 +00:00
thorpej f197609d93 Add some DIAGNOSTIC checks for inconsistent use of pmap_enter/pmap_kremove. 1999-05-25 20:33:33 +00:00
thorpej f311a1c308 Make a slight modification of pmap_growkernel() -- it now returns the
end of the mappable kernel virtual address space.  Previously, it would
get called more often than necessary, because the caller only new what
was requested.

Also, export uvm_maxkaddr so that uvm_pageboot_alloc() can grow the
kernel pmap if necessary, as well.  Note that pmap_growkernel() must
now be able to handle being called before pmap_init().

lukem e4a87aa1a9 * convert to using MI allocsys(). most ports were using an MD allocsys(),
although a couple still used the old pre-4.4-lite (?) mechanism.
* use format_bytes() to format the various printf()s that print out memory sizes
1999-05-20 08:21:42 +00:00
thorpej f98d358a1f Rework layer 2 protocol input routines. Instead of calling e.g. ether_input()
directly, call the function pointer (*if_input)(ifp, m).  The input routine
expects the packet header to be at the head of the packet, and will adjust
as necessary.  Privatize the layer 2 input and output routines, allowing
*_ifattach() to set them up as appropriate.
1999-05-18 23:52:51 +00:00
thorpej c10a926030 Allow the caller to specify a stack for the child process. If NULL,
the child inherits the stack pointer from the parent (traditional
behavior).  Like the signal stack, the stack area is secified as
a low address and a size; machine-dependent code accounts for stack
direction.

This is required for clone(2).

(nmbclusters * mclbytes), so that the right amount of KVA space is
allocated if those variables are patched.

mycroft 93768384ee Fix a bug in pmap_collect_pv(), even though nobody currently uses it:
When we put a page on the collection list, we must subtract NPVPPG from the
total free count: one for each pv_entry that's free in that page, and one for
each free pv_entry in other pages that we're going to eat by moving the ones
in the page being collected.
