gwr 0d541b4c08 Add dvma_malloc() for the ie driver. 1997-10-07 16:51:47 +00:00
gwr c669b1bdeb Do the cpu_kcore_hdr initialization a little differently. 
(also fix - was not setting pg_frame, pg_valid)
 1997-10-05 20:43:27 +00:00
gwr 6b27a0d34f Make cpu_reboot un-blank the screen (cnpollc(1)). 
Validate space in page zero for the kcore header.
 1997-10-04 20:03:46 +00:00
gwr 0ec1cda62f Move the call to cninit() up a level (easier to find). 1997-10-04 19:46:17 +00:00
gwr 3c0178f33d Make msgbuf stay in page zero 1997-10-02 01:15:04 +00:00
leo d4713d24c2 Implement the kernel part of pr-1891. This allows for a more flexible sized 
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

mycroft a9155c5057 Set the status word as well, and remove a bogus comment. 1997-09-12 10:29:20 +00:00
mycroft 982f24e698 Always initialize all registers in setregs(). 1997-09-12 07:00:30 +00:00
mycroft 16a8787248 Fix execve(2) and *setregs() interfaces so emulations can set registers in a 
more correct way.  (See tech-kern.)
 1997-09-11 23:01:44 +00:00
jeremy bbf76eb63e Implement pmap and va caching within C table managers to help speed 
up PV->(pmap,va) operations.
 1997-07-02 03:23:57 +00:00
mrg 552af779d2 bring mrg-vm-swap2 onto mainilne. 1997-06-12 15:46:19 +00:00

veego a204fb7981 Initialize machine from MACHINE. 1997-06-08 23:54:19 +00:00
jeremy 3f6f86d875 Undo changes which make pmap_xxxx_page() functions re-entrant; just block 
all interrupts which might cause re-entrancy.

Allow virtual addresses which are not managed by the MI VM system to
participate in the PV system.

Remove a few frivoulous TLB cache flushes.
 1997-05-30 07:02:14 +00:00
gwr e512003d6e Add non-inline version of _splraise. 1997-05-29 22:20:01 +00:00
jeremy 1b2aae80c2 Added new lock system for the two virtual pages used in temporary mappings. 
Allows pmap_zero_page() and pmap_copy_page() to be re-entrant.
 1997-05-28 04:28:52 +00:00
jeremy b53e0d4fb7 Coded to work with new lock system for tmp_vpages. 1997-05-28 04:27:00 +00:00
jeremy 0304ff6aed Implement code to dynamically size the number of page tables based on available 
RAM at boot.

Also did some cleanup of unused functions, updated several comments, and
removed unecessary 'XXX's.
 1997-05-20 06:01:19 +00:00
gwr a83cf310c1 The Hydra is 20 MHz and the Pegasus is 33 MHz. 1997-05-14 16:45:22 +00:00
gwr 5079510304 Make the "hydra" call leds_hydra() from clock_attach(). 1997-05-14 16:42:45 +00:00
gwr b209530013 Remove call to leds_init (it is already in obio_init). 1997-05-14 16:13:31 +00:00
gwr 1aa91b893d Eliminate references to vmspace.vm_pmap 
(also fix some comments).
 1997-05-13 17:17:12 +00:00
jeremy 3d8d0c485c Add call to leds_init() after everything has started up ok. 1997-05-11 06:15:09 +00:00
jeremy 3f7423a432 Wrap all label references with new macros in m68k/asm.h in preperation 
for ELF switchover. (eventually)
 1997-05-02 23:07:35 +00:00
gwr 24af362f60 Implement pmap_pa_exists() so that /dev/mem works. 
This was the reason ps (kvm_getargs) did not work.
 1997-05-01 15:00:11 +00:00
gwr b9a0ca59bb oops... 1997-05-01 14:58:20 +00:00
gwr 42f8cf900b Use unsigned when doing copy/xor check. 1997-04-28 23:43:56 +00:00
gwr cb96a536e4 Add a comment about obio_mapin(). 1997-04-28 23:38:47 +00:00
gwr 1046c915b6 Drivers that use obio_mapin should enforce OBIO attachment 
(just to be paranoid).
 1997-04-28 23:30:19 +00:00
gwr 678f326c7f Make idprom_init() figure out where the IDPROM resides. 
Add autoconfig glue, which currently just shows the
address where the IDPROM was found.
 1997-04-25 19:02:06 +00:00
gwr 4c64781365 Moved the actual model identification work into identifycpu(), 
which used to be in _startup.c:_verify_hardware().
Use sunmon_abort() in cpu_reboot() for now...
 1997-04-25 18:52:11 +00:00
gwr 9ae1b69554 Rename "Idle" to "_Idle" so clock.c can reference it. 1997-04-25 18:48:39 +00:00
gwr 25d7b6b348 Provide a struct representing only the clock. 1997-04-25 18:47:41 +00:00
gwr 885a1fc439 Add /dev/leds support. 1997-04-25 18:46:10 +00:00
gwr 2dd63e3378 Use bus_mapin, and minor tweaks. 1997-04-25 18:45:39 +00:00
gwr f7749f47fe Add "oclock" support for the Sun3/470. 1997-04-25 18:31:37 +00:00
gwr 8f9276c727 Move the _verify_hardware() work into machdep.c:identifycpu(). 
Call obio_init() after _vm_init() so we can use peek_byte() to
probe the idprom.  Be quiet in _save_symtab() when all is well.
 1997-04-25 18:29:58 +00:00
gwr 477a320277 Moved bus_scan() and bus_print() here from autoconf.c 
because they are now different in sun3 vs sun3x.
 1997-04-25 18:02:47 +00:00
gwr 3619a4da3d Rename obio_alloc to obio_mapin, update *_init declarations. 
Remove OBIO_P4_REG (not a fixed address, but per-device).
 1997-04-25 18:00:49 +00:00
gwr 963c410824 Change the OBIO address probe order a little, to allow determination of 
which kind of idprom and clock we have (3/80 vs 3/470 differences).
Fix a bug where obio_submatch() failed to copy some locators.
Rename obio_alloc to obio_mapin.  Add lots of comments.

jeremy b7dd41d4e2 Location of printer port registers for 3/80 was off. 1997-04-09 04:42:25 +00:00
gwr b5f838ad77 Add a comment. 1997-04-04 20:48:59 +00:00
jeremy 68755b199e Physical page status functions pmap_clear_reference() 
and pmap_clear_modify() weren't testing if the page whose status was being
changed was being managed.  This caused kernel panics with X11.
 1997-04-01 02:15:33 +00:00
jeremy b572daa4dc In-tree GNU ``as'' does not know of 'pmove <reg>,tt0' instruction. Changed 
instances of this instruction to hardcoded opcode statements.  Thanks to
jthorpe for pointing this out.
