isa_intr_{,dis}establish()) here. Make this file safely includable by
<dev/isa/isavar.h> and by all of the places in the i386 that are currently
including it, which means multiple inclusion protection and a few
otherwise-extraneous 'forward' structure declarations. isa_intr_establish()
and isa_intr_disestablish() now take as their first argument a
machine-dependent cookie of type isa_chipset_tag_t, which is also defined
here.
in VM86 mode.
Allow changing of *all* PSL bits in VM86 mode; some applications don't work
right otherwise, and all the nasty bits are virtualized anyway.
Make sure PSL_VIF, PSL_VIP, and PSL_VM don't show up in the user's view of
the PSL.
Use the bootpath[] array in setroot() to determine partition info in case
of boot devices of type DV_DISK. Also, precook more SCSI device info in
fake_bootpath() to simplify dk_establish().
in favour of storing the device pointer in the bootpath[] element corresponding
to the boot device. This also allows the opportunity to get to "intermediate"
devices (e.g. busses) should the need for this ever arise.
Call prom_iopen only on the first disk_open call, otherwise
only the first file open attempt ever works. Fixes PR# 1726
Both from der Mouse <mouse@Collatz.McRCIM.McGill.EDU>
Add prototypes to (most of) src/sys/arch/pmax/pmax. (The un-protytyped
parts still have pending merges with the Pica port.)
Fix splx() glitches in pmax/clock.c.
Delete old cpu/fpu identification from pmax/autoconf.c, use r4400/r4600/idt
aware code from Pica port, now in mips/mips/mips_machdep.c.
Delete unused multi-CPU autoconfiguration code; NetBSD/pmax does not
support decsystem 5800s anyway.
Update the pmax SCSI drivers (rz and tz) to use <machine/conf.h>.
Fix the driver entry points to have the correct signatures -- add
"ioflag" args to read() and write(), add "struct proc *p" arg to
open and close.
Stop using __BDEVSW_DUMP_OLD_TYPE, and update the rzdump and tzdump
entry points to have the correct, MI signatures.
NB: this is just syntactic sugar: both the caller and the dump entry
points ignore the additional args, and do exactly what they did before.
This must be fixed before using dump entry points in non-pmax drivers
(e.g., the MI scsi code).
add prototyped declarations for the callbacks which add old-style
(4.4bsd/pmax conf.old) SCSI controllers, and which configure SCSI slaves
on such controllers.
rewriting the SII driver to work with the MI scsi would be a better option,
if time were available, and the MI scsi code supported SCSI controllers with
an 8k upper bound on transfers.
the bus is configured, interrupts are handled, etc. define
eisa_chipset_tag_t and eisa_intr_handle_t types, and the following
functions:
eisa_attach_hook()
eisa_maxslots()
eisa_intr_map()
eisa_intr_string()
eisa_intr_establish()
eisa_intr_disestablish()
to do the right things for the i386.
Replace impliclty-sized types (u_long, u_short) used in
declarations of byteorder functions witho explicitly sized types
(u_int32_t, u_int16_t).
Avoids problems with using ntohl(foo) as (eg) an argument to printf().
Do not define __BDEVSW_DUMP_OLD_TYPE, as it breaks prototyping
of device dump functions, and should be port-dependent in any case.
The pmax 4.4bsd/pmax-derived drivers are being fixed, and the pica port
uses the MI scsi drivers already.
