wiz 40ac848024 Fix various misspellings of compatible/compatibility. 2001-06-11 01:50:48 +00:00
chs 821ec03ed9 replace vm_map{,_entry}_t with struct vm_map{,_entry} *. 2001-06-02 18:09:08 +00:00
lukem d84d2c6c85 add missing #include "opt_kgdb.h" 2001-05-30 15:24:23 +00:00
mrg 67afbd6270 use _KERNEL_OPT 2001-05-30 11:57:16 +00:00
mrg 3783ca5d30 define _KERNEL_OPT as well as _KERNEL. we will use this in the future to 
get kernel "opt_foo.h" headers, rather than _KERNEL && !_LKM.

chs ae0ddea4f6 in pagemove(), use pmap_k{enter_pa,remove} instead of pmap_{enter,remove} 
since buffer cache pages aren't really managed by UVM.
 2001-05-28 22:16:17 +00:00
chs 21b70bf745 assert that pmap_extract() succeeds. 2001-05-28 22:11:45 +00:00

chs 952609a853 fix printf format strings and the call to ncr53c9x_attach() so that 
this compiles again.
 2001-05-23 02:14:07 +00:00
chs b98b7c2224 turn on printf format-string checking and -Werror. fix all warnings. 2001-05-13 16:55:37 +00:00
chs b4de661569 switch next68k to ELF. highlight include: 
add "%" prefix to register names in assembly code.
change assembly functions to return pointer values in %a0 instead of %d0.
C symbols no longer prepend an underscore, adjust assembly code for this.
32-bit values are now 32-bit aligned instead of 16-bit aligned,
adjust structure packing and padding to override this where necessary.
make EXEC_ELF std, make EXEC_AOUT and COMPAT_AOUT_M68K optional.
use the MI loadfile() instead of several home-grown versions.

thorpej cf67ac7122 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
thorpej 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.

thorpej 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
thorpej 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
thorpej 69abdbf60c Undo a misguided previous change to the pmap_update() API. 2001-04-22 23:19:26 +00:00
thorpej 4738622712 Give pmap_update() an argument (a pmap_t) so that it knows which 
pmap it should be updating.
 2001-04-22 00:33:59 +00:00
thorpej 7f10ba88b1 #define away pmap_update() in <machine/pmap.h> so that no function 
call overhead is incurred as we start sprinkling pmap_update() calls
throughout the source tree (no pmaps currently defer operations, but
we are adding the infrastructure to allow them to do so).
 2001-04-21 23:51:14 +00:00
thorpej 15f731ee94 pmap_update() should not be equated with "flush entire TLB", it is 
used to process deferred pmap operations.  Since these pmaps don't
defer anything, pmap_update() is a noop.

fvdl c7f1462f3e Add machdep file for procfs. Currently only used for linux-style 
/proc/cpuinfo (only active when procfs is mounted with -o linux).
For ports other than the i386 this currently produces an empty
string.
