clear which switches the video signal on and which off.
Make all grf_??.c (which supported it) use the same polarity of the test.
While being here, use a > test instead of implicit != to make it extensible
to darker than dark values for power managment systems.
- grf_cv.c, grf_cvreg.h, ite_cv.c: some cleanups
- grf_rh.c, grf_rhreg.h, grf_rt.c: new blank ioctl and some KNF
- grf_et.c, grf_etreg.h, ite_et.c: new graphics driver for et4000 based board
(oMniBus, Domino and Merlin)
- grfabs_cc: fix PR#2034
- grfvar.h: new grfunit for GRF_ET4000_UNIT
- scsidefs.h: no longer useful
- zbus.c: new entries for: Piccolo SD64, oMniBus, Domino and Merlin
* for the M68060 part: store buffer and branch target cache aren't
enabled yet (this needs cleanup of lots of locore.s code which is a
maze of little passages, all a little different) (and it wasn't yet
tested in an accellerated Amiga, only in the DraCo).
I've included a workaround for 2 of the CPU bugs in chips with Masks
1F43G and earlier, but didn't bother to deal with the can of worms
in the [0-3]D11W chips. Be sure to get "68060 rev. 1" or more
reported at kernel startup time, or at least mention it (or the mask
revision, if available) when reporting problems.
* for the DraCo: only machines with a CIA timer.
I assigned machine id 32000+nn (0x7Dnn), where n is the machine
readable Quicklogic custom chip revision (also printed at boot
time). "Guaranteed to work" up to rev. 3, newer DraCo's aren't
guaranteed to have any CIA (we don't have a driver for the new timer
yet).
Supported are:
- MF-II keyboards on the native interface and A3000 keyboards via
the CIA.
- builtin SCSI interface (yet another instance of siop)
- CIA timer.
- Zorro II devices which don't do DMA (don't get mapped to Zorro II
address space in the DraCo)
- "local bus" devices which are autoconfigured by the boot rom
(should be all); only an Altais driver is there (looks like a Retina Z3)
Not yet supported are:
- native timer of newer machines.
- Real Time Clock.
- serial, parallel + floppy on the SuperIO chip (that is also: no mouse)
XXX You need an enhanced boot loader, which will committed in a few days.
XXX std.draco should and will go away.
- Added support for multiple floppy drives
- CyberVision64:
- has now a real console mode
- another bugfix for boards with the new S3 chip
- Ariadne:
- fixed crashes with aeput (mbuf failure)
- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
