thorpej aaf43a156e Make this build for a 3MAX-only kernel. 1998-05-21 17:41:29 +00:00
jonathan cb015e952e Resync 3max (kn02) support. 1998-04-25 16:29:06 +00:00
jonathan c7597ae8b8 Rework, based loosely on suggestions from Tohru Nisimura.. 1998-04-19 10:18:20 +00:00
thorpej 8a86fd47be It's Just Wrong to configure a KN02 system slot as an IOCTL ASIC, but
since it's currently done that way, nuke the gratuitous printf that
reports the behavior.

jonathan 383ff0cb59 * Use new defopt model-specific options and opt files.
Replace all DS5000_* and DS3100 ifdefs with ifdefs on DEC_ options.
* Use MI declarations, not pmax-specific, in model-specific init
  that uses baseboard (ioasic) registers.
* Further cleanup of machdep.c.  Clock-tick still needs more thought.
* Use 'ibus' names for 3100 baseboard devices in MI code.

jonathan 6975dc93a9 Split sys/arch/pmaxpmax/{machdep.c,trap.c} as suggested by Jason Thorpe:
* add "Platform" support inpmax/pmax/sysconf.c and pmax/include/sysconf.h
   (based on Alpha cpuconf.[ch], with a namechange to avoid clashes with
   support for  models of MIPS cpus. They  differ more than Alphas).

 * For each supported model of DECstation, create a separate file
   with the support for that model.  Use model codenames, since
   support is really baseboard-specific and CPU daugherboards can change.
   Move code from machdep.c and pmax_trap.c,
   Add sysconf (nee "cpuconf") support.

 * Rename model-specific functions to match sysconf names.

 * Clean up autoconf.c.  Use platform callbacks.

 * Retire pmax_trap.c.

Leaves  I/O bus configuration and console configuration untouched.

Other header files now include <mips/cpuregs.h> where necessary.

cgd 2a73ef60b7 change cfprint_t type definition to take a const char *, rather than
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).

mhitch fe55416706 Fix autoconfiguration stuff to more closely match the alpha - primarily
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.

thorpej 77abd102b7 New device attachment scheme:
- 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.

jonathan e229c8d175 Resolve pmax and alpha IOCTL asic driver differences, pass 1:
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'.

jonathan 5ea2ec2357 Re-write Decstation turbochannel autoconfiguration code to use the machine-
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.

jonathan 06bd2712e9 Update pmax kernel to compile with -Werror:
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.
1995-09-25 20:33:26 +00:00
jonathan 45d06a39e5 Change the signature of interrupt-handlers to take a void *
(a pointer to the softc) and return an int (indicating spurious
interrupts or other conditions.)

jonathan 2ddcaa8ac9 Fix references to ASIC_SLOT_RTC, which isn't yet defined on DECstations. 1995-08-29 09:43:37 +00:00
jonathan d21f86df37 Initialize the ioasic slot probe table for the 3MIN (Decstation 5k/1xx)
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".
1995-08-18 10:15:09 +00:00
jonathan a1a7750426 Move IO ASIC interrupt-enable outside #ifdef DEBUG, where it had
accidentally snuck in.  Clean up debugging messages and explicitly
give a warning on  CPUs the code hasn't been tested on.

jonathan 19e02269b2 New-style config (config.new) autoconfiguration code for Decstation
turhsturbochannel machines.  Lifted wholesale from cgd's Alpha
turbochannel code, with changes that reflect the slightly different
bus topology and `slot' numbering on Decstations.
