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.
1995-09-29 21:53:29 +00:00
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.
1995-09-28 20:02:50 +00:00
cd887a9930
Add "kvtophys()", which maps MIPS R2000 kernel-virtual addresses to physical addresses,
...
so they can (e.g.) be written to DMA mapping registers.
1995-09-25 20:36:23 +00:00
d1234038d4
Rename the force-all-pending-writes to memory function to wbflush().

0641f09bfb

1995-09-20 23:33:25 +00:00
7d7396c414
Make system calls conform to a standard prototype and bring those
...
prototypes into scope.
1995-09-19 22:53:47 +00:00
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.
1995-09-11 22:03:00 +00:00
fa13d32c41
Add splsoftnet().
1995-08-13 00:16:08 +00:00
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.
1995-08-01 06:58:57 +00:00
4525afdaeb
Add diagnostics for 5k/240 turbochannel interrupts, and clean up IOASIC clock
...
declarations.
1995-07-23 20:21:17 +00:00

remove unused cpu_exec() definitions. moved "broken swap" markers, for
...
ports that still need it, to types.h.
1995-06-28 02:55:18 +00:00
1c0be437b1
define __BDEVSW_DUMP_OLD_TYPE for ports where it's true. clean up

1995-06-20 20:32:22 +00:00
1305dc32df
Put parentheses around macro arguments
1995-06-16 02:07:33 +00:00
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.)
1995-05-31 00:25:06 +00:00
f90f8d10aa
Removing -DKERNEL, transition to _KERNEL has been completed
1995-05-16 22:24:17 +00:00
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.
1995-05-12 23:27:23 +00:00
214234c937
Fix MAXine interrupt mask routine

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
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.
1995-04-29 21:10:31 +00:00
b2c7420e5a
Fix performance bug in pmax MachFlushDCache(). Old code disabled icache
...
and wasn't unrolled. This code runs cached and unrolled, giving an order
of magnitude improvement in some cases (e.g., DMA-capable network devices).
In use at Stanford DSG since late January 1995.
1995-04-28 23:17:51 +00:00
026a077a5d
Check in source code actually containing changes in previous log message--
...
fixes to turbochannel-based DECstation interrupt enabling.
(I hate network firewalls that break rsh and remote CVS.)
1995-04-28 22:50:29 +00:00
523e8bccbc
Fix hardware interrupt-mask setup in the 5k/240 (3max)+ interrupt handler.
...
(A similar fix needs to be applied to the 3min and xine handlers.
This fixes a long-standing problem when booting with a card that
wants to interrupt (e.g., a network interface) would have interrupts
enabled before a handler was set up.
Add interrupt-counting code to model-independent interrupt handler,
and 3max (5k/200) and 3max+ (5k/240) md handlers, for vmstat -i.
Similar changes for 3min and xine are obvious but not done.
Add code for 5k/240 to read, and latch, the current value of the
IOASIC bus-cycle counter at each timer interrupt. The latched
counter is needed to accurately interpolate the bus-cycle counter value
as a high-resolution clock.
1995-04-28 21:48:11 +00:00
ef8023a47b
Check in changes suggested by Ralph Campbell: update variable names
...
to use turbochannel slot numbers, add a couple of extra slots, just
in case.

ANSI says that <stdarg.h>'s va_end macro must expand to a void expression.

1995-01-28 01:51:46 +00:00
9540190d45
This file, which will be included by <sys/cdefs.h>, will contain macros
...
such as __warn_references() and __weak_reference() which are actually
machine dependant. This will make it easier for ports that are being
bootstraped with ELF and ECOFF based toolchains.
This change also introduces a new macro, _C_LABEL(x). _C_LABEL expands
its argument, an identifier, to a character string of the identifier
name as it is represented in an object file.
For most ports, _C_LABEL(x) will expand to "_x", for ELF based ports
_C_LABEL(x) will expand to "x".
