leo 9f8316940b Use NOWAIT when malloc()-ing a buffer for switching screens. It might be
running from an interrupt handler.

leo f7d6d7c9b8 Don't clear the 'd_partitions' before starting to read the disklabel. Some
filesystems (iso9660) depend on the info they had already setup there.

leo ae019435eb Probe the 'mainbus' before the other busses. This gives less surprises when
adding things like SCSI controlers to the pci-bus.

tv b21bfbde11 Add -Wno-main conditional on compiler being gcc 2.8 or egcs. (This adds
a HAVE_GCC28 check-variable that can now be used to add other gcc-2.8
flags in cases where they may be useful, or to remove gcc 2.7.2 "bug
workaround" flags.)

cgd 3bbb7f7d45 Move pmap_map() function definition to MD headers, as appropriate. It's
an internal function, and the VM system shouldn't try to prototype it.
(Note that some ports _don't_ prototype it.)

thorpej 8354e68508 Remove "class" declarations, and add "devclass" declarations where
appropriate.  Fix several inconsistencies between device class and
attributes.  Mostly from Chris Demetriou.

a spare field.

1998-01-06 06:47:04 +00:00
thorpej a8f80ad4fd Fix a bogosity apparently inherited from when the Utah 4.3BSD code base
was converted to use Mach VM for Net2/4.4BSD.  The user segment table
pointer was originally stored in the PCB.  When Mach VM came along,
however, it was also stored in the pmap, and loaded into the PCB in
pmap_activate().  pmap_activate() would then note that the PCB's USTP
was now in sync with the pmap's USTP, and the low-level context switch
code would use the value from the PCB.

However, pmap_activate() would also load the hardware MMU context if
the pmap was the current pmap (or, in the case where pmaps can be shared,
such as in NetBSD, if the proc was the current proc).  The low-level
context switch code would then reload the hardware _again_ using the
USTP from the PCB.

However, the optimization of not calling pmap_activate() if "stchanged"
was false ended up causing some processes to use stale USTP values from
the PCB when the low-level context switch code reloaded the hardware!
This was noticed by using a real vfork(2) (which worked for some time
before failing, surprisingly!)

Since I'm hard pressed to find any real optimization here (since the
hardware was always reloaded once, sometimes twice!), the code now always
calls pmap_activate(), which uses the correct USTP value (the one in the
pmap).  The PCB's USTP is now ignored, and should eventually be g/c'd.

Another optimization can actually be performed, and I have added a comment
describing what it is, but have not yet implemented it.

Also note that most of the loadustp() functions where actually incomplete.
This has been corrected.  These functions should probably be split up into
MMU-specific operations, and called indirectly, rather than doing constant
run-time decision making based on values that will never change during the
course of a boot's lifetime.

prototype it in <vm/pmap.h>
1998-01-03 01:12:59 +00:00
thorpej dd966fca05 Change an argument name to PMAP_ACTIVATE() to more accurately describe the
semantics of the argument.
1998-01-01 20:05:23 +00:00
thorpej 287b63b321 - Make pmap_activate() and pmap_deactivate() take a struct proc *.
