conf/GENERIC:
conf/files.amiga:
- Bring in wsfont definitions.
dev/grfabs_reg.h:
- Add macros for decomposing palette entries.
dev/amidisplaycc.c:
- Support for fonts, either wsfonts compiled into kernel
or runtime-loadable by ioctl. Font width still limited to 8,
height may vary.
- Limited support for mapped displays. No way to adjust display
mode. Palette setting works.
- Prettier default palette (white on black).
- Probes correctly as WSDISPLAY_TYPE_AMIGACC.
- Support for screen blanking.
Actually, this is added to the siop2_script; should we ever support another
siopng board that does connect something else to GPREG bit 4, we'll have
to move this to C code and make it optional.
OTOH, by then we'll have switched to the MI driver by then.
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.
Currently this is a no-op on most platforms, so they should see no difference.

This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
(no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
will be requeued, or a REQUEST SENSE will be sent as appropriate.
Just before the merge syssrc has been tagged with thorpej_scsipi_beforemerge
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).
These calls are relatively conservative. It may be possible to
optimize these a little more.
We default to the (newer, more sane) 22.1184 MHz value, but set it from
the iobzclock variable (in Hz), which is initialized from the IOBZCLOCK
configuration option and patchable.
XXX we should time the clock at system startup.
- add ioblix_zbus to the GENERIC configuration.
