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.

scw 81be7c00b7 Compute PAGER_MAP_SIZE at runtime to avoid needlessly crippling large- 
memory models for the benefit of small-memory models.

Uses a heuristic of min(onboard_ram_size/2, 16MB).
 2001-04-29 07:53:56 +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).

kleink f06533a1ee Add definitions of C99 integer format conversion macros. 
XXX Fastest minimum-width integer types haven't been decided upon yet.
 2001-04-15 17:13:04 +00:00
kleink 739cb75837 Add definitions of C99 specified-width integer type limits. 
XXX Fastest minimum-width integer types haven't been decided upon yet.
 2001-04-15 15:29:02 +00:00
kleink cdcf9f46c5 Add definitions of C99 integer constant macros. 
Tidy Makefiles up a little.
 2001-04-14 22:46:19 +00:00
kleink a7c20e5788 Add definitions of C99 integer constant macros. 2001-04-14 22:38:33 +00:00
scw 9beeeabe1b Define a PAGER_MAP_SIZE of 4MB for the benefit of low-memory models. 
XXX: This may still not be low enough for models with less than 8MB RAM...
 2001-04-14 16:02:24 +00:00
scw c605c91bdf Fix bootline argument passing from the Bug PROM. 2001-04-14 13:43:07 +00:00
kleink 7affdab52e Add definitions of C99 minimum-width and greatest-width integer types. 
XXX Fastest minimum-width integer types haven't been decided upon yet.
 2001-04-14 12:19:49 +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.
 2001-04-13 23:29:55 +00:00
thorpej 2c4c690f14 Add the BUS_DMA_STREAMING flag. 2001-03-07 22:42:16 +00:00
thorpej d74e432ed3 Make softclock a generic soft interrupt of the API is available, 
adding the requisite void * argument to softclock().
 2001-01-15 20:19:50 +00:00
thorpej 45de366b2e Rename __GENERIC_SOFT_INTERRUPTS to __HAVE_GENERIC_SOFT_INTERRUPTS, 
and place the definition in <machine/types.h>.  This can now be used
as a flag to indicate whether or not <machine/intr.h> can be included
to get the generic soft interrupt API.
 2001-01-14 23:50:28 +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).
 2001-01-14 02:00:37 +00:00
scw 00627955a1 Some minor optimisations to avoid checking {cpu,mmu}type when 
the kernel was built for only one type of CPU.
 2000-12-20 16:53:50 +00:00
scw 8ace7abc75 A small splx()/spl0()/soft interrupt related optimisation. If we're 
dropping to spl0, use inline code to check if a soft interrupt is
pending instead of taking the hit of a function call to do the check.
 2000-12-10 18:43:02 +00:00
scw c5b6f43634 Define `splzs()' to be `splserial()' instead of `spl4()', which was 
wrong anyway since it blindly set SPL to 4 regardless of the prevailing
level.
 2000-12-10 18:00:24 +00:00
scw ac80517816 Add some #defines for offsets into the bugargs structure, and make the 
register names usable within assembly code.
 2000-12-05 21:57:13 +00:00
scw 634dc65636 Backout the last change; I'll deal with it another way. 2000-12-05 19:54:09 +00:00
scw 1f9f7cbe53 UPAGES -> 2 as recommended by Chuck Silvers. 2000-12-05 18:46:10 +00:00
scw 2ec144518f Add loadfile_machdep.h to list of installed machine headers. 2000-12-05 18:42:18 +00:00
scw 269a30a733 s/a6/fp/ again... 2000-12-04 18:48:18 +00:00
scw b29bcb645b The LOAD_TEXTA flag is required when loading a.out kernels. 
Also add some non-standalone versions for the benefit of installboot(8).
 2000-12-04 18:41:51 +00:00
scw c28723715c Prefix the register names with `%'. 2000-12-04 18:40:05 +00:00
scw e4326b372a Set things up so that DDB can get to the symbol table in ELF kernels. 2000-12-02 13:57:05 +00:00
tsutsui a8fdbdec1c Remove unused pcbb() macro. 2000-12-01 17:57:43 +00:00
scw 97490c9997 Add __attribute__((__packed__)) to cpu_disklabel to get around 
the ELF padding/alignment constraints.
 2000-12-01 00:02:22 +00:00
scw d3251e5074 Prepare to switch mvme68k bootloader over to the MI loadfile(). 2000-11-30 21:20:43 +00:00
scw 7248616dee Ditch an extra % in a register prefix, and s/a6/fp/ 2000-11-30 21:18:07 +00:00
scw 614e494d9e Add register prefixes. 2000-11-29 09:18:32 +00:00
scw fecb49d172 Add register prefixes. 2000-11-29 09:09:39 +00:00
scw 7d191ffe77 Revamp the bus_space(9) implementation: 
. use a structure for the tag instead of an integer constant,
 . add bus_space_{peek,poke}_N() (and G/C `badaddr()'),
 . fix a few drivers which have dependencies on the implementation.
 2000-11-24 09:36:40 +00:00
scw 06e91c089b Replace the inline C versions of bus_space_{read,write}_N() with 
inline assembler. This generates significantly more efficient code,
and trims ~1KB off the size of an mvme68k GENERIC kernel...
 2000-11-24 09:05:55 +00:00
scw b6f0a678dd Add support for the m68060-based machines: MVME-172 and MVME-177. 
CPU support taken from a combination of NetBSD/amiga and NetBSD/x68k.

At this time, MVME-172 works but MVME-177 is untested. Since the '177
is otherwise identical to the MVME-167, this should *just work*.
 2000-11-20 19:35:28 +00:00
thorpej ecf0470012 We use 4K pages on the mvme68k. Override PAGE_SIZE and friends to 
be compile-time constants.
 2000-11-14 19:12:58 +00:00
scw 5f6802db57 Add pmap_zero_page_uncached(), and the PMAP_PAGEIDLEZERO macro. 2000-09-22 08:27:00 +00:00
scw 18deccffca Add IPL_SERIAL. 2000-09-19 19:31:34 +00:00
scw 53d57897d0 Use the complete ethernet address stored in nvram on mvme162/mvme167 
instead of faking the first 5 nibbles a'la mvme147.

Apparently recent mvme16x boards have a new 5 nibble prefix...
 2000-09-15 08:50:24 +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.
 2000-08-25 01:04:06 +00:00
thorpej 58e7a6954b Add spllock(). See spl(9) for details. 2000-08-22 19:46:26 +00:00
scw 3f2adcb2b0 Checkpoint of code to add VMEbus slave support using vme_dmamap* and 
vme_dmamem*.

This is still a work in progress, but seems to DTRT on mvme167 so far.

TODO:
	. Get VMEbus slave mode going on mvme147. This should be easy.
	. Fix up the A16 slave mappings.
	. Bounce buffer support. (Messy, but pretty much a `must have'.)
	. Figure out how to deal with `location monitor' interrupts
	  within the framework. (Useful for Busnet, among other things.)
	. It would be nice to make use of the VMEchip2's DMA facilities...
 2000-08-20 17:07:41 +00:00
scw b77bc217e1 Pull a bunch of common code from vme_pcc.c and vme_two.c into 
the new mvmebus.[ch] files, and put down some initial code to
deal with VMEbus slave mode.
 2000-08-13 17:00:51 +00:00
scw 0d5db1f645 Bump DFLDSIZ to 32MB since 16MB is no longer enough for some 
parts of `make build'.
 2000-07-27 14:48:58 +00:00
scw 8f4e16a29e G/C some obsolete HP-UX related flags, and prevent multiple 
inclusion while I'm here.
 2000-07-27 14:26:15 +00:00
scw 2f335ce72b Nuke __BROKEN_DK_ESTABLISH, and add __HAVE_DEVICE_REGISTER. 2000-07-25 20:52:27 +00:00
scw 78abb015f5 G/C the IIO* #defines. They're no longer needed. 2000-07-24 11:20:47 +00:00
