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.

the locators.
In wdcprobe_internal() set the WDCF_32BIT flag if the data32 io handle
is set.
All transfers to and from the data register now check for softc flags
to see if 32 bit transfers are enabled i.e. reading drive parameters
and doing a dump will use 32 bit transfers as well.
of cache-index incompatible virtual mappings for a physical page may be
required for hardware without secondary (level 2) cache to detect and
correct virtual coherency problems. I'm not sure this is really needed
anymore, since pmap_prefer() took care of of the cache-index
incompatible mappings that I have seen. Count the times a page is
cache inhibited in enter_stats if DEBUG.
Wait for memory instead of panic() on failure to allocate a page for the
segtab or segmap [from OpenBSD arc port]. Also check for malloc()
failure on allocation of a new pv entry and panic().
Increment resident_count when adding a new page to a pmap [also from
OpenBSD]. Process resident size is now valid.
cache flush operations required on a virtually-indexed, physically-tagged
mips3 with no L2 cache to provide cache-coherence exceptions.
(Similar to what's needed with a virtually-indexed, virtually-tagged cache.)
In the probe routines check the mainbus attach args mb_iobase field
to verify that the iobase did not default as an iobase address needs
to be specifically specified.
they have different podule ID's.
Always attach the driver even if it appears to fail the tx test as there
appear to be a collection of cards around that will fail this tx test but
will actually work ok - This problem needs further investigation.
- It is now possible to handle devices that want "looping" DMA,
e.g. the SoundBlaster correctly. The WSS and SB drivers use this.
To do this several new methods were introduced in audio_hw_if.
- Different silence handling (forced by previous change).
- The audio driver can now be mmap()-ed, but due to problems in
the VM system only for writing for now.
- The OSS (Linux) audio emulation takes advantage of some of the
new features.
faults. Use curpcb, which always points to the current pcb. If curproc
was NULL when the kernel faulted, the trap handling would fault recursively
and the kernel stack would overflow.
