jonathan ffd8d4cdc7 Additional fixes to complete the NetBSD/1.1B config changes:
Update the kn01 (3100 aka pmax) interrupt handler to use XXX_cd instead
of XXXcd.

jtc 2ce5f1478b Add _BSD_WINT_T_ definition so we can handle wint_t type added in NA1. 1996-03-16 01:31:45 +00:00
jonathan dc6fdf6cdc First commit of Per Fogelstrom's port to the Acer pica r4400/isa machine. 1996-03-13 04:58:04 +00:00
jonathan ff27dbbcf9 Revert pmax stdarg.h and varargs.h to versions from 1995-11-13. Those
versions work correctly; at some point between then and the immediately
preceding revisions, the "stylistic" changes to one (or both) stdarg.h
and varargs.h broke passing doubles to printf().

jonathan bf52fa8269 The prototyping `fixes' broke vmapbuf() and vunmapbuf(), due to a "sz"
parameter parameters shadowing locals.  Replace vmapbuf() and vunmapbuf()
with the Alpha-port versions, which are cleaner (use round_page(),
trunc_page(), etc.)

jonathan cb7e6f2e0f Change last argument of ktrsysret() call: pass rval[0], not rval, as
ktrsysret() expects.   Tracing of  rval[1] remains an open problem.

christos 2c8314f73c vm prototype changes 1996-02-05 02:06:38 +00:00
jonathan 1f780158bb Redo the locore interrupt counters reported by vmstat -i:
* add a new enum decstation_intr_t to trap.c, naming each instrumented
  interrupt symbolically, and used to index into intrcnt[].  Change the
  model-specific interrupt handlers to use the decstation_intr_t when
  updating interrupt counters.
* add instrumentation to the kmin and maxine interrupt handlers.
* fix a bug that counted each hardclock interrupts on the kn02 twice.

The hardcoded mapping from locore names to units is gross; but these
counters will hopefully be useful in identifying interrupt hot-spots
and PPP problems on the 3MIN.

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 df51f8395d Change MachEmulateBranch() to be able to read an insn from user space.
Kernel-debugger breakpoints in user space, or FP insns that cause
underflow in a delay slot, should now work properly. Single-stepping
of arbitrary user processes, from user level, should be added.

jonathan 2852152043 Reserve a number in the machine-dependent range for PT_STEP, in
case the kernel-debugger implementation of single-stepping ever works
with user code.
1995-12-21 09:28:36 +00:00
jonathan c0f958f6be Add support for ptrace PT_GETREGS and PT_SETREGS for NetBSD/pmax:
* define PT_GETREGS and PT_SETREGS in pmax/include/ptrace.h
 * Flesh out the stubs in pmax/pmax/process_machdep.c to handle
   those requests.
 * Now that "struct reg" is actually used, remove the bogus
   #ifdef LANGUAGE_C around its definition, and redo pmax/include/reg.h
   so that the definitions needed by locore.S are in a separate file,
   pmax/include/regnum.h.
 * update locore.S to match.

jonathan ae1b64d888 Fix btoc()/ctob() typo in reading physical memory that stopped ps
from reading process argument lists.
Allow kernel-virtual memory reads to read the message buffer, since
dmesg needs it.

jonathan b543578236 Add a missing "nop" in a delay slot in the floating-point exception
handler.  Gradual underflow and fp emulation now work correctly.
Proper denorms also fix strtod() inaccuracies and Gcc's "enquire" program.

jonathan cd887a9930 Add "kvtophys()", which maps MIPS R2000 kernel-virtual addresses to physical addresses,
so they can (e.g.) be written to DMA mapping registers.

jonathan 9a914b5b01 Rename the Decstation 2100/3100 interrupt functions from "pmax_<func>"
to "kn01_<func>", to avoid confounding a model name (PMAX) with the name of the
entire port (pmax).


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.)

Pass softc pointers to the scsi and ethernet kn01 (DS_PMAX)  drivers,
rather than having unit numbers wired into the base-level interrupt
handler.

jonathan 6a99440efd Add prototypes for most functions. Fix typo where statements
intended to increment interrupt counters for vmstat -i (i.e., "ctr++")
on 3100s had just a single "+", and hence had no effect.

jonathan ae4eae4f63 Change reference in asm code from ``__mcount'' to ``___mcount'', to be
consistent with the (default) prepending of underscores to identifiers.

Because this reference is inside an ASM string it's too hairy to
conditionalize to support different toolchains that don't prepend underscores.
(Just don't do profiling with  such  toolchains.)

jtc f90f8d10aa Removing -DKERNEL, transition to _KERNEL has been completed 1995-05-16 22:24:17 +00:00
jonathan 4175c2819f Redo 3MAX+ (5k/240) interrupt enable code.
Instead of being a no-op, kn03_intr_enable() sets the sw copy of the
interrupt-enable mask *and* writes it into the IO asic intr-enable
register.  Boot code sets the sw copy (kn03_tc_imask) to something
sane (KN03_IM0, with tc option slots turned off).  Tested and works.
Interrupt code for other IOASIC machines should be redone so that
interrupts for devices are enabled by drivers, rather than by
cpu-specific boot code.  Functions common to all IOASIC machines
(PSWARN?) should be done by asic_init().

Checked in without the above changes so that 3MAX+, MAXINE and 3MIN
interrupt-(enable,handle) can converge.

jonathan be2c7f3d13 If we panic inside trap(), Do a stack traceback before printing the trap log.
Also change the stack-traceback code to avoid having multiple returns
(and thus multiple stack pops) because with gcc -O2 that breaks the
heuristic that a "jr ra" preceding the PC precedes code to push the
current stack frame.  Which breaks stacktrace() before it even
traces past itself :-(.  Use a goto instead.
1995-05-02 19:51:52 +00:00
jonathan fb9f07db36 Update MIPS stack backtrace code to trace through locore functions,
traps, and interrupts  The earlier (4.4bsd) code didn't do the first two, and
got the last one wrong.  Also print some functions (e.g., trap handlers)
by name.  Add hook to use something other than printf() as the output
function, e.g,. for kernel debugging.
Tested with the `native' toolset, but not ELF format kernels.
(i.e., unwinding the $GP register is not tested.)

The stack backtrace code that interprets and unwinds stackframes is still
opaque and stylistically awkward.
