indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.
- 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.
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
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.
* 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.
