thorpej 772da350d4 Disable the message buffer during crash dumps by clearing msgbufenabled,
not msgbufmapped.

jeremy a1efa84a4d Modified the comments for the recentlty implemented pmap_map() function. 1998-02-09 19:56:37 +00:00

gwr 5b69e41858 Default the interrupt priority in match functions. 1998-02-08 05:05:54 +00:00
gwr 5193e1e30e Factor *peek out of bus_subr.c and move it to autoconf.c
(to reduce duplication).  Add bus_tmapin and bus_tmapout
for use in probe functions (gets a temporary mapping).
Add bus_mapout() to undo bus_mapin() if needed.

mycroft 15ae963bea When dumping, print out the device number as major,minor. 1998-01-24 16:46:23 +00:00
gwr c292276dcf Change our DVMA map from the last 16MB to the last 1MB because that is
the only part that is visible to VME masters, and is adequate space.
This allows the "si" driver (on VME) to use DMA transfers.

gwr 56100bea19 When calling iommu_* functions, use IOMMU_VA_MASK. 1998-01-22 22:12:36 +00:00
gwr 0c50bf6487 No need to print the size (it's constant). 1998-01-22 22:09:11 +00:00

gwr cc1b4e4724 In pmap_bootstrap_copyprom, copy only the last PTE from the PROM's
DVMA segment (for the page reserved by the PROM).  If we copy all
the mappings, pmap_enter_kernel may complain about finding valid
PTEs that are not recorded in our PV lists.  Make pmap_remove_pte
do something reasonable if it finds a PTE for a managed page that
has not been recorded in the PV lists.  (Plus other minor stuff).

gwr 58126a3b29 Separate pmap_activate() from _pmap_switch(), so the latter can remain
equivalent to what locore.s:cpu_switch does with in-line assembly when
PMAP_DEBUG is not defined.  Also do splimp/splx in pmap_activate.

gwr 43013bccbb Use MONEND instead of DVMA_SPACE_START in the "DDB convenience" symbols. 1998-01-22 21:35:27 +00:00

thorpej d14e18faa9 Make pmap_activate() take a proc *. 1998-01-02 20:10:26 +00:00
jeremy 070bd37c1b Pad out table manager structures so that all the members in the contiguous
table manager array allocated in pmap_startup() are properly aligned for
faster bus access.

tv 0a558b3f1f Standardize COMPAT_SUNOS -- remove all references to
sunos_exec_aout_makecmds() in machdep.c for various architectures and put
it in exec_conf.c like the other emulations; rename exec.h to
sunos_exec.h.

hannken 50be28153c Change order of include files. See PR #4532. 1997-11-18 12:40:31 +00:00
gwr 9420004b46 Remove the for-loop that wants to map multiple msgbuf pages.
Multiple msgbuf pages will not work without a redesign of
the kernel VM layout, so let's not pretend we can do it.

gwr b4f7e0ec3d Remove the autoconfig glue. This driver is mandatory,
and the match/attach functions did nothing anyway.

jeremy d2d5e50d91 Rewrote the comments about the operation of the I/O mapper to make them more
accurate and (hopefully) easier to understand.

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)).

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 16a8787248 Fix execve(2) and *setregs() interfaces so emulations can set registers in a

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.

RAM at boot.

Also did some cleanup of unused functions, updated several comments, and
removed unecessary 'XXX's.
