struct scsipi_adapter; they were not used.
Add a scsipi_ioctl entry point to struct scsipi_adapter. This will be
used to issue ioctl commands to the host adapters.
Inspired by PR #6090, from Matt Jacob.
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.
multi-channel driver), or to SCSI_CHANNEL_ONLY_ONE if a
single-channel driver.
(2) use scsiprint() rather than a locally-defined autoconfig print
function, and kill any locally-defined print function.
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).
* 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.
