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).
the IOASIC attached devices. The DS3100 will now configure properly.
Fix the DS5000/25 IOASIC table entry for the RTC so the RTC interrupts
get enabled.
Fix up a moved include file.
- 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.
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'.
independent TC support in sys/dev/tc/tc.c and sys/dev/tc/tcvar.h:
* Change the tc autoconfiguration tables to use a struct tc_attach_args
instead of the ad-hoc structure.
* Change all pmax device drivers to use a `struct confargs' that's
assignment-compatible with sys/dev/tc/tcvar.h `struct tcdev_attach_args'.
Devices that can be present on a TC or as ioctl asic/mainbus builtins
use the same `struct confargs'.
* Eliminate the `BUS_CVTADDR()' macros which the pmax port inherited from
an old, now-obsolete sys/arch/alpha snapshot.
* Update the comments and debugging code in interrupt handlers to
be consistent with the machine-independent TC support.
Other commits that overlap the same source files include: re-enabling
clock-tick interrupts earlier, and counting hardclock ticks for vmstat -i.
Update TURBOChannel and ioasic interrupt-establish routines to pass on their
device argument as a "void *", since that's how all the pmax interrupt handlers
are declared.
and MAXINE (Decstation 5k/xx), instead of setting them to NULL.
New-config kernels should work on those machines now.
Rename the definition of the struct cfdriver for the IO ASIC from "asiccd"
to "ioasiccd", as the config-file name changed from "asic" to "ioasic".
turhsturbochannel machines. Lifted wholesale from cgd's Alpha
turbochannel code, with changes that reflect the slightly different
bus topology and `slot' numbering on Decstations.
