kanaoka e2749d2799 Add "Sanity check the entry" code to avoid Compatibilty Holes 
(0xa0000 -- 0xfffff).

fredette db8595f14f Much bus_dma work. When destroying a map, unload it if it's 
loaded.  Added more comments.  Fixed the perspective of a 24-bit
device from the original sun4 code to match the sun2.  For now,
we don't double-map pages into DVMA space by hand, we're back
to using pmap_enter.  Be more paranoid about saving and
restoring the MMU user context.

fredette 026720119b Added support for the Sun SC scsi controller. 2001-04-18 03:38:38 +00:00
fredette 451d8d47e1 Added support for creating a bus_dma tag for the mbmem bus. 2001-04-18 03:34:54 +00:00
fredette 5f19315baa Now define IPL_BIO. 2001-04-18 03:30:14 +00:00
fredette 68230340aa Fixed a bug in db_write_text where on exit we would bash 
a PTE in whatever user context happened to be set on
entry.

thorpej 1bf3f87777 Fix a problem with kcopy()/copyin()/copyout() on MP systems 
that became apparent when UBC was added: store a pointer to
the process itself, not a pointer to ci->ci_curproc.

This gets us back to where we were before UBC went in: MP
kernels get to single-user mode, and can run processes on
both CPUs, but things go south when we try to come into
multi-user mode.

thorpej a51a1d8cdd - Get rid of the prot bits in the mem_clusters[] array when 
reserving RAM in the bus_mem extent map.  Problem pointed
  out by Artur Grabowski.
- Work around a slightly annoying bit of behavior exhibited by
  the UP1000 firmware.  The UP1000 firmware reports the space
  consumed by the "ISA hole" in the same MDDT entry as two
  chunks of RAM (on either side of the hole) used by the PALcode,
  all as one "reserved for PALcode" chunk.  We must take this
  into account when reserving RAM in the bus_mem extent map.

pk 4485b7f720 pmap_enter(): 
* turn ad-hoc `pmap resources allocated during sleep' into a panic condition
  (this should all be prevented by higher level VM locking).
* arrange for ENOMEM to be returned if PMAP_CANFAIL is on, and malloc()
  and/or pool_get() fail.

toshii 58165a53a2 Make masked interrupts don't bring CPU out of idle mode. 2001-04-17 17:12:40 +00:00

toshii de8e20334a Map a page needed for entering idle mode. 
Also, use zero memory at physaddr 0xe0000000 to clean D cache.
 2001-04-17 16:10:47 +00:00
toshii ffe7f4da8a Fix a bug crept in the previous revision. Call dosoftints() after 
reenabling interrupts.
 2001-04-17 16:07:13 +00:00
toshii a78b59337f Overhaul interrupt handlers. 
- Set the match register before calling hardclock() to prevent
 clockintr lossage.
- Better handling of match register overrun case.
 2001-04-17 15:58:51 +00:00
toshii 0c1210c6b3 Make the debugging hack needed for DEBUG_BEFOREMMU functional again. 2001-04-17 15:53:04 +00:00
toshii 5373b5ab86 Special care must be taken in order to run statclock at 128Hz. 
For now, change statclock rate to 64Hz for simplicity.

Thanks to Ross Harvey for pointing out this issue.
