5b39541e48
New generic disk framework. Highlights:
...
- New metrics handling. Metrics are now kept in the new
`struct disk'. Busy time is now stored as a timeval, and
transfer count in bytes.
- Storage for disklabels is now dynamically allocated, so that
the size of the disk structure is not machine-dependent.
- Several new functions for attaching and detaching disks, and
handling metrics calculation.
Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.
For usage and architectural details, see the forthcoming disk(9) manual
page.

6d6c652f18
New driver for the Sun SCSI-3 VME and 4/100-series SCSI "Weird" controllers,
...
utilizing David Jones' new MI NCR 5380 code. Ported from the sun3 ncr_si.c
and "sw" DMA code written by me.
This driver contains user-configurable "options", which can be set via the
"flags" directive in the kernel configuration file. By default, only
DMA is enabled. DMA completion interrupts and reselection may be enabled
by setting the appropriate bits with "flags". See si.c for details.
Note that DMA completion interrupts and reselection don't yet work on the
4/100 controller. I don't know why, and it's unlikely that I'll have
the opportunity to find out any time soon. DMA does work, and results
in a considerable performance increase.
DMA, DMA completion interrupts, and reslection all work on my 4/260 (VME)
system with modern SCSI-II disks.

However, doing so on all 4 ports would cost a whopping 64KB (at 4096 entries

allowing the size for the keyboard and mouse ports to be reduced (to 128)
which should be adequate for the 1200 baud they use.

Prevent synch negotiation on ESP100 chips
1995-11-28 22:49:31 +00:00

Lots of major and minor bug fixes and changes.
...
- properly do MSG_IN handshaking, so we can actually receive multi-byte msgs.
- do synch negotiation (now that the above works).
- handle disconnects.
There are a few trial-and-error bits at points where the docs I have are
particularly ambiguous about the state of chip and/or SCSI bus.
Things to do:
- more cleanup
- deal with MSG_OUT phase better
- keep some "config reg 3" bits per target (ie. FASTCLK and FASTSCSI).

cleaned up bootpath code:
...
- v2 openprom disk boot generates "/sbus/esp/sd@3,0" which we translated
into "/sbus@0,0/esp@0,0/sd@3,0"... this caused esp.c to reject
the bootpath because it was looking for sbus slot/offset 0,0.
changed the code to generate "/sbus0/esp0/sd@3,0" to fix this
panic.
- when generating fake boot paths, generate them with unit numbers
rather than slot/offsets (thus, /obio@0,0 becomes /obio0, as
does vmel and vmes).
- fixed up comments to reflect these changes
tested new code on: 4/280 (diskless), 4/360 (diskless), 4/360 ("xd" disk),
4/370 (scsi disk), ss1 w/v1 openprom (diskless),
ss1 w/v1 openprom (scsi disk), ss2 w/v2 openprom (diskless),
ss2 w/v2 openprom (scsi disk).

anyway as noted by Chuck Cranor.
