Turbochannel as well as the IOASIC. It should now work on the 5000/200.
Removed the "aborts" which could leave the disk trashed when the abort
rebooted the system. Fix the data corruption problem by clearing the
FIFO before starting a data transfer.
* Change MachEmptyWriteBuffer() to wbflush(). Should use TC mi names tc_mb(),
tc_wmb, tc_syncbus() but I'm not sure which each wbflush() should be.
* Add prototyped forward decl for asc_Dumplog() and add an explicit void
return type.
* Remove unused variables.
alpha. At some point in the future, those headers should be provided
on the pmax, but until then, things are #ifdef'd so that the old
headers and definitions are still used. Pass a bus_chipset_tag_t
to the TC bus attach code and to devices, on the alpha.
naming conflicts between bus attachments on ports that can have
multiple instances of the LANCE.
Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_reset)()
to take a struct ifnet *, rather than a unit number.
remove their 'integrate' (usually defined to be 'static') keywords.
when lance drivers are split up by attachment, more than one file will
reference the copy/zero functions (i.e. not just the file that pulls in
am7990.c... and eventually inclusion of am7990.c should go away entirely).
chip-independent clock code. 'clock' has been renamed 'mcclock' 'clock'
has been renamed 'mcclock' (since it's a driver for that particular
clock, and since eventually there may be another clock chip driver),
and now attaches via seperate match/attach functions to both TC and ISA.
This removes a whole lot of #ifdefs...
to {mainbus,tc,ioasic}_cd.
Change ioasic config name from "lance " to "lance". Correct for
pmaxes, perhaps not for Alphas.
Boots and runs under load on a 5000/200. Hangs during boot on an ioasic
decstation; pmax autoconfig needs fixing.
Add Decstation-3100 baseboard support (untested).
change tc_submatch() to compile with the new device-attach scheme:
the TC bus uses a 'submatch' function which checks device locators
and then calls a match function.
Instead of calling cf->cf_driver->cd_match(), we now need to call
cf->cf_attach->ca_match().
Rename the extern declaration of `tccd' and `ioasiccd' in
src/sys/dev/tc/{tvar.h,ioasicvar.h", respectively, to be
`tc_cd' and `ioasic_cd', to match the 1.1B-style definitions.
- 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.
but unconfigured (or unsupported) devices printed at boot time.
The device list is woefully incomplete, because i didn't put much time
in it, and because i don't know good "human names" for many TC devices.
planned changes in other sections of code.
(2) expands the use of config_found() in tcattach() in-line, so that
tcsubmatch can be invoked there, rather than being invoked by
individual drivers.
(3) tcbus_attach_args now includes a turbochannel speed flag.
(4) compare a string in tcbus_attach_args against tc bus driver name,
to better allow attachment of multiple busses to the same parent.
Rename the ioctl asic register and slot macros from ASIC_<xxx> to
IOASIC_<xxx>, to be compatible with the machine-indpendent names in
sys/dev/tc/ioasicvar.h. The pmax code still uses
sys/arch/pmax/pmax/asic.h, as some of the registers and offsets
defined there are not yet defined in sys/dev/tc/ioasicvar.h.
Rename the ioctl asic base-address pointer from `asic_base' to `ioasic_base'.
Use the device address in the attach_args structure, instead of
using the deprecated BUS_CVTADDR macro.
Change the Mach derived asc driver to use "SCSI_PHASE_xxx" instead of
"ASC_PHASE_xxx", as the latest version of the Mach driver does.
