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.

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.

itojun f79137a3f1 it looks that gas configured for little endian output runs as 
big endian assembler, sometimes.  explicitly have -little to specify
little endian output.

itojun d8ba6d06be procfs_machdep is per port (not per CPU). 2001-01-17 00:44:33 +00:00
fvdl c7f1462f3e Add machdep file for procfs. Currently only used for linux-style 
/proc/cpuinfo (only active when procfs is mounted with -o linux).
For ports other than the i386 this currently produces an empty
string.

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.

thorpej a3ec356d52 splimp() -> splvm() 2001-01-14 03:22:04 +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 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.

jdolecek e9e91a0fb5 split off thread specific stuff from struct sigacts to struct sigctx, leaving

chs c62d17a551 rationalize the use of b_flags for geteblk() buffers. 
rather than assigning to the whole field, set or clear individual flags,
which implies that the B_BUSY and B_INVAL flags will remain set.
this allows us to make the assertion in brelse() that B_BUSY is set,
which is the purpose of all this.

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.

thorpej 72a24b4eae Add an align argument to uvm_map() and some callers of that 
routine.  Works similarly fto pmap_prefer(), but allows callers
to specify a minimum power-of-two alignment of the region.
How we ever got along without this for so long is beyond me.

msaitoh 2cb1f4181a sync with i386's revision 1.133: 
It's legal to mmap pages in the lower part of the stack (<limit),
	and use them, so allow this by relaxing the check for it.
