- use board address space > 4 MB, instead of iszthreepa(), to detect Z3-mode
boards. We dont want the bus, but want the address configuration.
- s/CV64CONSOLE/CV3DCONSOLE/
- s/cv3d_zorroIII == 1/cv3d_zorroIII/ and s/cv3d_zorroIII != 1/!cv3d_zorroIII/
the CyberVision64 driver. Modified by Tobias Abt with some bugfixes
from Bernd Ernesti.
ZorroII is at the moment not supported and there is a small problem
with the Console driver where you just get a black screen, but the
system boots and you can use X11 without a problem.
The changes is to allow some limited mixer manipulation through
the audio device (instead of the mixer device).
This rendered 4 methods in audio_hw_if unused so garbage collect these.
pseudo-device rnd # /dev/random and in-kernel generator
in config files.
o Add declaration to all architectures.
o Clean up copyright message in rnd.c, rnd.h, and rndpool.c to include
that this code is derived in part from Ted Tyso's linux code.
This will be used by certain SCSI drivers to limit the length of DMA transfers
when the serial port is running at higher speeds. GVP and Phase5 DMA
interfers significantly with CPU execution, and significantly increases
receive buffer overruns (silo overflow). Reducing the DMA transfer length
can reduce the overruns.
- MIT syntax to Motorola syntax moveml register lists (for better readability)
- comment alignment
- remove commented out debug or alternate code from early DraCo support
development.
(I wanted to do this stuff for a long time, but always had "more important"
things to do.)
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.
NOTE: due to hardware requirement of the AGA chipset, the framebuffer width
has to be a multiple of 64 bits. An 800x600 display will use a memory width
of 832 bits, which the current X server can't handle. To get a usable
display, the width needs to be 832 or 768.
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.]
* 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
without an 'a' partition. We open the RAW_PART partition instead.
Without this, a boot partition on the 'b' or later partition of such a disk
won't be found.
is for "standard PC i/o stuff" at known and constant locations, e.g. when
multi-io chips are used on non-ISA mainboards.
Implement drsupio.c, the DraCo version of this.
Attach the generic com.c to this bus.
Remove the old drcom hack.
Currently, this is only kind of a wrapper around the *_sicallback() function
family. This way, we'll only break the new driver if it doesn't work.
After more drivers are converted, we'll change it to be the other way round.
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.
at the same time instead by using two different calls. This enables
it to check more easily if the combined mode is all right.
- Improve the error checking in audio.c.
- Add a new audio property, AUDIO_PROP_INDEPENDENT, show if the
play and record settings are independent.
- Fix some buglets in audio.c.
- Change the way attach and open works to allow multiple audio
devices.
- Split the mulaw.c file into two to avoid dragging in mulaw
convertsion when they are not needed. Add 16 bit alaw/mulaw tables.
- Change the way audio properties are gotten.
- Recognize more versions os SoundBlaster.
- 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.
- 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

- Return EINVAL for gv->disp_flags and sync-on-green.
