However, for the time being, getting full rates out of HIPPI or SCSI are what
interests us at NASA, so we'll hew to this bias.
able to read SXP registers (instead of panicing). Probably have done a bit
of setup overkill- we now alloc some scratch memory for the 2100 that I thought
I would need for the Port database, but so far I haven't needed to retrieve
the port database. Well, early days yet.
* make map and alloc take 'flags' rather than 'cacheable,' for
more flexibility.
* rename BUS_BARRIER_* to BUS_SPACE_BARRIER_*, for consistency.
* rename bus_space_copy_* to bus_space_copy_region_* and make their
defns match the updated spec.
Backward compatibility is provided by defining __BUS_SPACE_COMPAT_OLDDEFS,
which is currently defined by default.
- Add entries for the LC520, Color Classic, and PB150 to intvid_info[].
- Make the PB150 a Duo-class machine, as it seems to work better this way.
Now that we're doing the latter, it points out something I missed a long
time ago when I added Duo support: CLASSDUO was being ignored in
mac68k_set_io_offsets().

initialization.
The console device is now given as string ("pc", "com0".."com3").

not included in a kernel without procfs, and it seems wrong to pull
all of procfs_subr.c in for just that one function. Perhaps this
should go into a new file instead?
FreeBSD by Sean Eric Fagan, but a bit different. This makes the checks
in the same places as sef's FreeBSD patch, but does not hardcode the
"kmem" group into the kernel, and also does a check identical to the
(3) and (4) checks in the NetBSD ptrace(2):
(1) it's not owned by you, or is set-id on exec (unless
you're root), or
(2) it's init, which controls the security level of the
entire system, and the system was not compiled with
permanently insecure mode turned on.
-Separate KGDB port initialization and softc related stuff to allow
KGDB to be attached in early system startup, before autoconfiguration.
-Export the variables needed by md code to hand-craft bus tag/handle.
-Fix initialization to enable interrupt by line break.
-Call DDB/KGDB at line break (move DDB call from the softirq handler
to the hard handler because it should work without a tty attached too).
Compute CPU speed(MHz) and loop multiplier for DELAY() based on

Note that I only did this for the US type keyboard maps.
This and all other such options should be documented, and perhaps
rennamed with consistant PCCONS_ prefixes.
o option DISPLAY_ISO8859 enables the display of iso-latin1
character set (instead of the IBM page code 437)
o option FRENCH_KBD, GERMAN_KBD or NORVEGIAN_KBD implement
support for national keyboards (implies DISPLAY_ISO8859).

2) Add option PCCONS_REAL_BS which (for US keyboards only) forces
backspace to really be backspace and not delete. Intended to close
PR #2264 submitted by Greg Woods. He wanted it changed for everyone
-- I thought adding a kernel compile option was friendlier.
Note: Both of these sets of options really should be documented in an
i386 specific version of options(4).
(address error faults), as well as other reported problems:
- Simplify grfmv_phys() to work like grfiv_phys(), and eliminate the
second argument to both, as we don't use it anyway.
- Handle fbbase and fboff consistently throughout. Closes PR 3862.
- Eliminate grfaddr() by pulling it into grfmmap(), which is the
only place it was used, previously.
- grfmap() now gets the physical address of the framebuffer from
the appropriate driver, rather than try to compute it by itself.
Be careful with aligning the base to a page address and increase
the length of the mapped region appropriately. Closes PR 2867.
a command to the 82586 for every frame to be transmitted. Instead, a
single command sets off the execution of a chain of commands consisting
of alternate XMITs and NO-OPs, where the link fields in the NO-OPs are
set to loop back onto themselves until the next XMIT is ready to go.
This trick found on a Linux WEB page.
All this induces reasonable transmission performance in my old multibus
adapter. The receiver performance is still abysmal..
- Change the way attach and open works to allow multiple audio
devices.
- Split the mulaw.c file into two to avoid dragging in mulaw

- Recognize more versions os SoundBlaster.

Use the IS_PODULE macro for checking manufacturer and podule id's

Added missing .data directive prior to the curpcb declaration.
Fixed the calling of the cpu sleep function in idle(). The sleep function
takes a single argument which is the sleep mode. This is currently unused

sense code for zero and if found repeat the request sense. This solves
a bug in the sbic driver when accessing JAZ drives that results in
faulty sense data being returned following a transfer. A retry returns
the correct information.
This is probably showing up a more fundemental bug in the sbic driver
and will probably have to wait for a complete overhaul of the sbic
driver (planned) for a perfect fix.

For the podulebus_bs_tag structure set the shift to 2 (the current

Use the cookie to provide the register shift in podulebus_subregion().

- Add grfvideo_mode->disp_flags to select interlace, doublescan,
sync-on-green and horizontal/vertical sync polarity.
- Add some constants for grfvideo_mode->disp_flags.
This fixes a wrong output from grfconfig /dev/grf[23]
- changes for the grfconfig interface:
- Remove gv->hblank_stop and gv->vblank_stop.
- Only print doublescan and interlace flags. Horizontal/vertical sync
polarities are not yet supported and sync-on-green will never be
supported.
- Remove gv->{hblank_stop,vblank_stop} and use the other grfvideo_mode
values to set ba->data.
- Add gv->disp_flags to select interlace.
- Not yet supported are: doublescan, sync-on-green and the horizontal/vertical
sync polarity.
This makes it possible to use xfree values for grfconfig.
- changes for the grfconfig interface:
- Remove gv->{hblank_stop,vblank_stop} and calculate HBE and VBE from
gv->{htotal,vtotal}.
- Add support for gv->disp_flags to select interlace, doublescan and
horizontal/vertical sync polarity.
- Return EINVAL for gv->disp_flags and sync-on-green.
This makes it possible to use xfree values for grfconfig.
- Use interrrupt #6 instead of #2. #6 is the default interrupt and there
seems to be a problem with Cyberstorm 060 and #2.
- Set the interrupt register before enabling the interrupt.
- GC M2INS
- minor cleanup
- Switch from +hsync/+vsync to -hsync/-vsync.
