instead of bp->b_bcount. The I/O operation may have changed bp->b_bcount,
and not all of the kernel virtual memory will be freed. This will result
in the VM system putting pages back on the free list which are still
mapped. This may cause a deadlock later trying to enter pages into
the kernel pmap. [See PR#4120 for more details.]
* exit after providing an estimate if -S was given. the PR used -e,
but checking around indicated prior art in Solaris usin -S.
* remove superfluous 'DUMP:' prefix in two messages
* initialise blocksperfile explicitly (not necessary, but everything
else in that section gets initialised, so be consistant :)
* display the ``pretty'' name of the dumped directory, so the user
knows if it's a subset or not
-optionally, use Martin's direct hardware access to serial lines
-optionally, new console autoselection method: select serial console
if a character is seen within 1 second
-move awaitkey() here, it can be shared by different bootloaders and
it is used by console autoselection
-collect information about console selection in a "bootinfo" defined
structure, for passing to the kernel
separated "nfswrapper.c"/"nfs.c".
This nfs.c differs from the stand/lib/libsa one in that it does not
have a separate mount() function - the mount is done in open().
on EV56 and later processors that have the "amask BWX" bit clear. These
instructions will be used to implement non-swizzle bus access functions
on newer systems, such as the new AlphaStation 500s with EV56 and 21172
PCI chipsets.
See "Alpha Architecture Handbook, Version 3", DEC order number EC-QD2KB-TE.
* support chip clocks != COM_FREQ, by introducing sc_frequency (for the
mainline code) and adding a frequency parameter right after the rate
parameter to comcnattach() and com_kgdb_attach().
- Make com_isa and com_multi initialize sc_frequency to COM_FREQ.
- Make i386/machdep.c and alpha/dec_xxx.c call com*attach() with the freq.
parameter.
* supio_attach_args get two more fields: a sc_ipl and a sc_arg, both ints.
- com_supio uses the first for interupt establishment (all childs will, as
soon as they exist) and the 2nd for sc_frequency.
- drsupio passes sc_ipl alway as 5, and for the "com"s, sc_arg as 16*115200
- hyper will pass sc_ipl as 6, and sc_arg as 16 * 460800
- Fix a few bugs in the software single-stepping support code, where
VMS PALcode ops were being checked, rather than OSF/1 PALcode ops,
causing erroneous results in the "exception return" and "unconditional
branch" predicates.
- Add the BWX instructions ("ldbu", "ldwu", "stb", "stw") to the
"load" and "store" predicates.
