mycroft 753fe3a25a Fix mkdep problems due to missing flags. 1996-02-09 02:21:13 +00:00
jonathan b5c68cb4cd Add serial-console support that works with `new-style' (config.new) autconf
code.  Substantially the same code tested on a 5k/240. Should work on a
5k/1xx.  Not tested on a  MAXINE, where the single unit may break the
PROM-channel-number to driver-channel-number mapping.
1996-02-08 02:26:34 +00:00
jonathan 4ab4b73b40 Support kernels configured without an ASC (e.g, 3100-only configs) or
without an SII (e.g., TURBOChannel-only configs).  Only the same old,
static, set of old-config devices and old pmax rz/tz drivers is
supported.
1996-02-06 02:13:18 +00:00
jonathan f239350d79 Fix braino in (partial) 5100 support: the 5100 is a DS_MIPSMATE, not a
DS_MIPSFAIR.
1996-02-06 01:59:46 +00:00
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.)
1996-02-06 00:31:51 +00:00
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 600a82037b A semicolon was missing from the SYSTEM_LD_TAIL stanza that converts
from elf to netbsd a.out, causing the mv to fail; add one.

jonathan 10a140d34d Rename SCSI phase manifest constants from ASC_PHASE_* to SCSI_PHASE_*,
as the newer version of the Mach 53c94 driver does.
1996-01-31 23:38:55 +00:00
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'.
1996-01-31 08:46:42 +00:00
jonathan 219b1ef218 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.
1996-01-31 02:53:39 +00:00
jonathan 4c0067c40b Remove config.old files for pmax. They should have been removed before
the NetBSD-1.1 release, as they have not worked or been supported for
some time.

jonathan 05ef657fb8 Some newer scsi-2 or scsi-3 drives reportedly return more data in
response to an inquiry command than was allocated here.  Add 1024
bytes extra padding, just to be safe.
1996-01-30 04:47:16 +00:00
jonathan 5ea2ec2357 Re-write Decstation turbochannel autoconfiguration code to use the machine-

jonathan 56ffba38d4 Fix how the cmap entries are updated, as contributed by Arne Juul
(arnej@pvv.unit.no). Xservers should now be able to set colours correctly.

1996-01-14 21:06:47 +00:00
jonathan 04d66273af Remove the config.old sys/arch/pmax/dev/{scc.c,if_le.c}. The "new" config
equivalents (back-ported from NetBSD/alpha) are in sys/arch/pmax/tc, and/or
in sys/dev/tc.
1996-01-12 05:38:27 +00:00
jonathan d51b06e19a Add lots of debugging to the TurboChannel autoconfiguration code. 1996-01-11 05:59:23 +00:00
jonathan 28cf41d710 Change the order of members of struct confargs, to be closer to
the sys/dev/tcvar.h TurboChannel configuration structures. (the initializers
in sys/arch/pmax/tc were already changed; the structure definition wasn't,
which broke autoconfiguration.)
1996-01-11 05:57:04 +00:00
thorpej 5b39541e48 New generic disk framework. Highlights:
- New metrics handling.  Metrics are now kept in the new
	  `struct disk'.  Busy time is now stored as a timeval, and
	  transfer count in bytes.

	- Storage for disklabels is now dynamically allocated, so that
	  the size of the disk structure is not machine-dependent.

	- Several new functions for attaching and detaching disks, and
	  handling metrics calculation.

Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.

For usage and architectural details, see the forthcoming disk(9) manual
page.
1996-01-07 22:01:38 +00:00
jonathan 8472af018d Update a kludge from 4.4bsd/pmax: DECstation PROMs force the clock to
be in 1972 or 1973. If the clock is set to the actual time, the PROM
appears to reset the chip date to 1972 at each reboot.

Change the "year offset" from 22 years to 24 years (good till 1997)
until this code is replaced with something that uses the chip as a
seconds-since-beginning-of-year clock (encoded as a date, relative to
1972-01-01 00:00:00).
1996-01-07 15:38:44 +00:00
jtc 2fce159ff8 Changed name of sigaltstack's ss_base field to ss_sp to match XPG4.2 and

jonathan 22a5271164 Remove pmax/tc/tc.h; use dev/tc/tcvar.h instead. 1996-01-03 20:47:19 +00:00
jonathan 659c4a2ece arch/pmax/tc -> dev/tc, pass 1:
Eliminate pmax/tc/tc.h. Use dev/tc headers for pmax port. Change pmax TC
autoconfig tables to use structs (mostly) compatible with dev/tc/tcvar.h.
Move TC console search to tc.c.
1996-01-03 20:39:10 +00:00

1995-12-28 19:16:31 +00:00
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 37d37e0791 Change the pmax framebuffer driver to reflect the rcons changes as negotiated
with pk:
Use dev/rcons/files.rcons in the pmax config file.
Use "rasterconsole" as the tag in pmax/conf, and modify the pmax
framebuffer pseudo-device drivers (fb and rcons) to us rasterconsole.h and
RASTERCONSOLE for compile-time configuration of the rcons pseudo-device.
Modify the pmax rcons pseudo-device driver to initialize a little-endian,
QVSS-compatible font (set its ascent, and set the rconsole structure to
point to that font) before calling rcons_connect().

Tested on a cfb.  The ascent may be wrong (or at least, not be aligned with
the hw cursor sprite) on a 3100.

jonathan f28ebc66ca Fix SCC bug that broke getty on pmax SCC lines: if RAW and LITOUT were

jonathan 95a27d405b Update pmax kernel to compile with -Werror:

jonathan cd887a9930 Add "kvtophys()", which maps MIPS R2000 kernel-virtual addresses to physical addresses,

1995-09-25 20:36:23 +00:00
jonathan 06bd2712e9 Update pmax kernel to compile with -Werror:

are declared.
1995-09-25 20:33:26 +00:00
jonathan 27361456c5 Force a delay after calling SCC_WRITE_DATA() to give the chip
registers time to settle. DELAY(2) is reportedly enough.  Without the
delay, output characters are occasionally doubled.
1995-09-25 04:30:43 +00:00
jonathan 7bb66692c0 Add fine-grain clock code which uses the 25 MHz TURBOChannel bus-cycle
counter on 5k/240s to interpolate to microsecond-resolution clock
in microtime().  Only the "rev B" ASIC in 5k/240s is known to have
this counter; other models may or may not.  This gives microsecond
resolution at user-level, and up to 40ns resolution (modulo the
nominal 5(?) 40MHz cpu cycles for reads to complete) in the kernel.


Change the IOASIC reset function to set up the DMA mapping for the
53c94.  Allocate 16 Kbytes of DMA buffer for 53c94 ASCs under an IOASIC,
as the 3MAX baseboard and TC options  have 128 Kbytes of static
bounce buffer, and the drivers really _should_ support 16Kbyte
I/O requests. (They don't always.)

Give the LANCE a hard reset on 5k/240s, just to be on the safe side.
(the 5k/240 I use sometimes reported errors at boot time.)

jonathan 2991316b06 Remove unecessary references to arch/sparc/rcons/raster.h, and some other lint. 1995-09-20 05:36:13 +00:00
jonathan 3589d052f0 Add gory debugging, because I don't have access to a MAXINE to test
the baseboard framebuffer driver with rcons and it reportedly didn't work.
1995-09-20 05:19:54 +00:00

jonathan b216a24d04 Rename the 4.4bsd/pmax framebuffer glass-tty console structs to
"struct pmax_fbtty".  Remove most of its fields, since the fields
in the struct fbinfo render most of them unecessary, and the pmax
now uses rcons anyway. Moe the lk-201 keycode definitions to lk201.h,
so rcons can use them too.

jonathan 1d976e39b9 Change pmax framebuffer drivers to use Ted Lemon's port of the
NetBSD/sparc rcons glass-tty console pseudo-device driver, via
the "fb" generic-framebuffer pseudo-device driver.

Individual framebuffer device drivers are now autoconfig glue,
and initialization code for a set of vdac/ramdac-level methods,
called "fbdriver", that's used by all the pmax device drivers.
All the handlers for user-level requests (open/ioctl/read/write/close)
are moved into the fb pseudo-device driver, which uses the
the "fbdriver" methods to work on any given pmax hardware driver.
Framebuffers  supported are: sfb cfb mfb xcfb pm.

Move the qvss (pm) -style mmap()ed device interface, kernel tracking
of mouse button/movement events, and placing mouse/keyboard
events in an mmap()ed ring buffer, out of the framebuffer device
drivers and into separate source files. The fb pseudo-device driver
uses the qvss-compatible interface, since that's what the (R5) X
server uses.

jonathan 1e95db0970 Commit a copy of pmax/asic.h from my development source tree, since
the pmax lance driver that uses the machine-independent am7990.c driver
needs some definitions for it.  This is a partial re-merge of NetBSD/alpha's
tc/asic.h back to the pmax, with the addition of symbolic #define's
for registers and bits in registers that are pmax model-specific.
1995-08-29 11:52:00 +00:00
jonathan 9557f68db3 Change pmax (asc and sii) SCSI drivers to use "needs-flag", as the
drivers have  been fixed to not require "needs-count".

Add back the lines for the "rcons" console driver, even though it's
not merged into the pmax port yet, as conf.h was patched to include
"rcons.h".  Adding the device here, but not configuring it (e.g., in
GENERIC) keeps conf.c happy until rcons code is merged.
1995-08-29 10:12:48 +00:00
jonathan 5124d90b3b Work around a NetBSd/pmax kernel bug inherited from 4.4BSD: the DEC
TURBOChannel cfb has a vertical-retrace interupt that cannot be disabled
in software. 4.4BSD and NetBSD don't supply an interrupt hander and
simply neverenable interrupts from slots with a cfb.  This has never
ever worked with a cfb in a 3MIN (Decstation 5000/1xx), where a TURBOChannel
card in slot 0 (or 1 or 2) interrupts at the same IPL as spl0() (or spl1
or spl2), and there's also never been support for selectively enabling or
disabling those interrupts on a 3MIN, in either NetBSD or 4.4BSD.

This  revision add an interrupt handler for the cfb, used only on 3MINs,
so that a 3MIN can boot with a cfb as console, and enable/disable of TC
slot interrupts can be debugged. (Serial consoles via ioasic SCCs still
don't quite work,  and simply clearing the relevant bits in the R3000 cause
register is apparently over-ridden by a subsequent spl0() somewhere else.)

jonathan 8522bd48f3 Move the pmax scc driver from sys/arch/pmax/dev to sys/arch/pmax/tc,
as it's a driver for a device under a TC IOASIC.   The Alpha port also
has its scc driver in tc/scc.c, and the pmax driver scc is nearly the same
as the Alpha.
1995-08-22 04:28:41 +00:00
jonathan 7560ab9b68 Rework the pmax scc driver, which hadn't changed much from the 4.4bsd
pmax driver, to be diffable with the NetBSD Alpha driver. Specifically,
the pmax driver now uses register names dev/ic/z8530.h. The driver now
uses new-style config and dynamically-allocated softc structures.  The
driver no longer resets the "other" channel on an SCC when changing tty
parameters. The #ifdef'ing away of processing of the output clist for
non-console lines is no longer done.  (Non-console serial ttys might even
work now.) Other discrepancies between the pmax and alpha drivers, which I
don't understand yet, are marked by XXXes.

The 4.4bsd pmax console redirection code is still present, protected
by #ifdef TK_NOTYET. Diffs from the Alpha scc driver are now minimal.

Verified to boot on a Decstation 5k/240.
1995-08-21 21:42:10 +00:00
jonathan 97cf65df4a Change pmax ASC driver to use dynamically-allocated softc structures.
Concomitant changes to code that prints driver/unit name: use dv_xname
and dv_unit, instead of doing pointer arithmetic on elements of the static
softc array.

Remove support for old config.  The old-config "driver" structure
is still present, because the pmax non-MI SCSI driver needs it.

Merge some off Per Fogelstrom's changes for the Pica driver,
which uses the machine-independent SCSI code. This is #ifdef'ed
out until the DMA is fixed to work on Decstations, too.

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

All devices except SCSI disks and tapes are found using new config only.
SCSI disks and tapes are configured using a table edited from an ioconf.c
produced by config.old.

Boots multi-user on PMAX, 3MAX and 3MAXPLUS.  The old-style "slot hand fill"
functions for those machines, and the old TurboChannel configuration
main loop, have been removed.

Since new-style config runs later in boot than the old pmax turbochannel
probing, we no longer know what devices will be configured when consinit()
is called. Use PROM output until autoconfig is finished.

as the DECstation scsi code can't poll, and hangs if interrupts
are disabled.

rzwrite() and rzread().  tzwrite() and tzread() are utterly untested.
tzwrite() should also check for write-protect, or handle writes to a

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 03c9dc7a48 Fix long-standing bug in NetBSD/pmax interrupt initalization on
Turbochannel machines with an IOASIC.

After an interrupt is taken, the IOASIC interrupt enable mask is
and'ed with the kernel's interrupt-mask variable.  This masks
off any interrupts that were enabled after the hardware interrupt-enable
mask was set. Due to this bug all iynterrupts must be enabled before
the first interrupt is taken. (Interrupts enabled later aren't on in the
ioasic intr-mask  register, so they aren't on in (sirm & kernelmask),
which is what used to get written back to the ioasic interrupt-mask
register.  	Fixed, and tested on  on 3MAX+ but not xine/3min.

If this patch perchance breaks on Xines or 3mins, the old code can be
re-enabled by changing the #if 0 in machdep.c to #if 1.

jonathan 64b99b333d The pmax 3100 interrupt-init code is broken: cpu_startup() enables
interrupts before it calls configure().  On 3100s, this can result in
the ethernet interface interrupting before leprobe() is ever called.
Be a bit more defensive in leintr(), where it was dereferencing a null
pointer.  This reputedly fixes the oft-reported problems of 3100s not
ooting unless they're on an idle net or had a hard reset done before boot.
(Reworking the config code completely would be nice too.)

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.

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.

jonathan 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.

bootstraped with ELF and ECOFF based toolchains.

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".
