timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.
* 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.
Fix a bug in pt_enter_ptpage which caused MMU faults on low-mem conditions.
Change siop drivers to better handle sync.
Remove diag. done for ide -- its redundant as the ROM does similar.
fixed ite_filter to not panic if typing before the device is fully setup
All thanks to osymh@gemini.oscs.montana.edu (Michael L. Hitch)
amiga goes: config.new *and* /sys/scsi.
clock code coerced into a single .c file adding an accurate usec delay().
disklabel.c updated to DTRT, code to write RDB's to be added soon.
sbic (old scsi) converted over to new scsi and config this covers about
90% of users. Other drivers soon.
