thorpej babefc5331 Add BUS_DMA_READ and BUS_DMA_WRITE flags, that hint the back-end 
at dmamap load time that the mapping will be used for a unidirectional
transfer of the specified direction.

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.

kleink fe3c9ceaf7 * Move definitions of exact-width integer types from <machine/types.h> 
to <sys/types.h> and <sys/stdint.h>.
* Add a new C99 <stdint.h> header, which provides integer types of
  explicit width, related limits and integer constant macros.
* Extend <inttypes.h> to provide <stdint.h> definitions and format
  macros for printf() and scanf().
* Add C99 strtoimax() and strtoumax() functions.
* Use the latter within scanf().
* Add C99 %j, %t and %z printf()/scanf() conversions for
  intmax_t, pointer-type and size_t arguments.

uch 95f0d5c680 add RTC control register 1 defines. 2001-04-22 16:50:17 +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 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.
 2001-04-21 17:25:01 +00:00

thorpej bf2dcec4f5 Remove the use of splimp() from the NetBSD kernel. splnet() 
and only splnet() is allowed for the protection of data structures
used by network devices.

marcus b6c1c5d49a Altentries should also be marked as functions, to keep linker happy. 2001-04-09 20:31:20 +00:00

msaitoh c090c1cfe5 temporary fix a serious pmap problem with dummy PMAP_{MAP,UNMAP}_POOLPAGE(). 
To fix correctly, set IOM_RAM_BEGIN with P0 addr instead of P1 addr and
fix machdep.c and pmap.c.
 2001-02-19 17:51:22 +00:00
uch 78af56fcfd move VM_PHYSSEG_MAX, VM_NFREELIST, VM_FREELIST_DEFAULT defines to 
machine/vmparam.h

thorpej c8cdb12913 Add some comments about P/USEG 2001-02-02 18:25:04 +00:00
thorpej ef2315d256 Rewrite how mod/ref emulation is done. In particular, make 
modified attribute checking actually work.  Previously, a
page could be reported as modified even if it wasn't!  This
is very bad, and e.g. caused the VM system to attempt to
"clean" pages of read-only files.

Only lip-services is paid to referenced attribute emulation.
This could be improved.

msaitoh 61831529f2 add some macros for 8bit PCMCIA access 2001-01-30 04:15:10 +00:00
thorpej d85a75f583 Make sure everybody has an splvm() and equate it with splimp() (splimp() 
is the historical name for this interrupt level, and the historical name
is going to go away in the near future).

itojun 1e7e3274f4 split MACHINE_ARCH sh3e[lb]. userland build still needs checking. 2001-01-04 07:03:21 +00:00
takemura c5fd828440 replace 'long long' with int64_t to compile stand alone program with 
compiler other than GCC.

itojun efa2b7073c make mbstate_t bigger (32 -> 128 bytes). 
XXX if you have libc after citrus locale import, please recompile libc,
and your applications that use mbstate_t (rather rare).  really sorry
for the mess.
 2000-12-26 10:35:28 +00:00
itojun 823498203f populate _BSD_MBSTATE_T_. add warning regarding to rune_t. 2000-12-21 06:03:47 +00:00
marcus 724713366e Made weak_alias create correct labels on sh-elf. 2000-12-14 18:47:30 +00:00
msaitoh d191cbf210 add interrupt mode into wdog 
To use:

	ioctl(fd, SIOWDOGSETMODE, &val)

	val:	WDOGM_RESET	-> reset when counter expired
		WDOGM_INTR	-> print PC when counter expired (new!)

This interface is still under experimental.

 2000-09-04 05:48:35 +00:00
thorpej 4db6fc7542 Make need_resched() take a "struct cpu_info *" argument. This 
causes gives a primitive form of processor affinity.  Its use in
roundrobin() still needs some work.
