Various sun4m-related changes straight from Aaron.
1996-03-31 23:38:29 +00:00
e0344005b4
Changes to match 4m-aware locore.s. Note changed `trapbase' and
...
`sparc_interrupt_{44c.4m}' labels.
1996-03-31 23:35:20 +00:00
e743dda2a9
Update for 4m locore.s. Remove some items, since locore.s now #includes
...
param.h
1996-03-31 23:28:03 +00:00
cf4009e56c
Include support for sun4m timers and counters: hardware register layout
...
has changed. There is a counter for each CPU (currently, just one supported).
1996-03-31 23:24:59 +00:00
8de1fd22bc
Add sun4m support. Many, many changes..
...
Note on multi-architecture kernels: most architecture dependent traps are
forked off directly by having a separate trap table for each (sun4,sun4c,sun4m)
This reduces the number of tests on `cputyp' significantly, and it's easier
on the mind. There are still some entry points that need to test `cputyp',
most notably microtime().. yuck.
1996-03-31 23:19:22 +00:00
6d76616bf0
The sun4m IOMMU "device".
1996-03-31 23:09:32 +00:00

Aaron's SRMMU/sun4m pmap implementation.

Attempt to work around a hardware bug that screws up DMA on the 4/100.
...
Apparently, some early 4/100 DMA controllers do illegal memory access on
large ( >= NBPG ) transfers at the end of the transfer. This appears
as SI_CSR_DMA_BUS_ERR in the csr. To work around this, we simply
transfer the (up to 3) missing bytes from the bpr. We were doing this
anyway, so the work-around is to ignore the bus error.
BUT! I goofed when I implemented the "left-over byte" code for the sw!
It *should* be correct now. Keep metrics (acceeible via DDB) on the number
of 1, 2, and 3 byte clean-ups, as well as the number of "clean" transfers,
just so we can get a clearer picture.
Thanks to Andrew Gillham <gillham@whirlpool.com> for noticing this!

depending on the nature of the panic, so we avoid it.

Three distinct changes:
...
- Better disklabel handling. While a disklabel isn't used
in the driver, some versions of the OpenPROM insist on
one being present in order to boot from floppy. These
changes provide a default label (in a way similar to how
the SCSI disk driver provides a default) so that a user
can more easily place the label on the disk.
- Fix semi-bug in bootpath handling. It appears as if the
bootpath can appear in a couple of formats: "/fd@0,0", which
is what bootpath_fake() creates on v0 proms and may be
passed by some v2 proms, and "/fd0" which is what the
v2 prom on my SS2 passes. We now handle both formats.
- Use a mountroot hook to eject the floppy and wait for
the user to insert a filesystem floppy if we're the boot/root
device.

- make xyc->iopbase point in the kernels DVMA space rather than at the
normal malloc'd KVA. this isn't compatable with sun4m [doesn't
have a kernel DVMA space] and will need to be changed later (XXX).

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.

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.

851669ceab
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).
