scottr eb910c35ce From Ken'ichi Ishizaka: correct the calculation of the frame buffer 
offset by masking off garbage bits in the DAFB v7.  This has been
tested at all resolutions and common color depths on the LC47x.

scw 52b5bc5eb8 Duh. My last change broke mvme147 support. 1999-04-27 18:12:44 +00:00
thorpej b1a4c46dab Fix a typo that prevented this from compiling. 1999-04-27 17:37:18 +00:00
nisimura 3e9afa8b4d - Save Mach_splX() calls which don't fit well with DECstation. MIPS 
spl machinary will be reworked, someday.

thorpej 5d82bfc656 Garbage-collect VM_MBUF_SIZE. 1999-04-26 22:47:34 +00:00
thorpej b8073b401b Garbage-collect the VM_MBUF_SIZE constant. Instead, use the size 
(nmbclusters * mclbytes), so that the right amount of KVA space is
allocated if those variables are patched.

ad 0c221127eb More fixes to get the PXG working and keep the PX happy. 1999-04-26 12:05:11 +00:00
ad e54fa8abad Fix silly bug where fbconnect() doesn't realize that it's already been 
called during early console initalization, then pouts because there appears
to be n+1 framebuffers. This whole thing is a mess.
 1999-04-26 12:03:53 +00:00
nisimura 56a9b84b91 - MIPS processors do not impose inclusive (nesting) interrupt levels with 
their interrupt lines.  The notion and implemention of 'spl' are left
for how target ports approach to it.
 1999-04-26 09:42:14 +00:00
nisimura 9e798fbe20 - Forgot to commit these two. 1999-04-26 09:36:05 +00:00
nisimura c33ad91e49 - Sweep machdep.c; mostly imported from a development branch. Little 
exposure of TC device any more.  Correct comments which are no longer
feasible.  Reorder declarations and definitions.  Introduce 'clkread'
pointer to pull up model dependent high resolution timer value.  Have
prom_systype() call.
- Place routines for model dependent high resolution timer.
- Program IOASIC registers inside os_init() call and nuke ioasic_init().
 1999-04-26 09:23:21 +00:00
ad d52e1e73df Add cdev declaration for `px', major 98. 1999-04-26 04:42:10 +00:00
ad 4e3888516e Many fixes to support PXG, PXG+ and PXG+ Turbo. Interrupt handling is 
totally broken for the PXG and will remain so until more documentation is
available. This destroys the queueing, hardware clipping, and VDAC update
mechanisms on the PXG.

ad 613a381d71 Update configuration to match `rasops' fixes and config glue. 1999-04-26 04:25:38 +00:00
jonathan 9c39aaeeca Add common SYSV* options (from i386). 
Add "options LKM", since with ELF/ECOFF format kernels it should now work.

ender e544636cde Disable ASC interrupt enabling for now. We don't currently use it, and 
it seems to be causing hangs at attach time on LCII's.

Insert badaddr() check before read the ROM.

pk's "BSD-style (clauses: 2; no acknowledgements)" pattern

ross a1cca18262 Implementing bus_space_barrier(9)::isa_bs_barrier() with panic(9) 
does in fact get you a barrier, but it's unnecessarily drastic.
Fixes kern/7431 "SHARKs with a serial console and com.c 1.59.2.1 won't boot".
 1999-04-22 10:12:41 +00:00
leo 098c344c9b Make sure that we can link against the libsa.a library. It looks like a 
gross hack, but I don't know how to fix this in another way.
 1999-04-22 07:17:01 +00:00
chs 05b971dd5f in pmap_pageable(), rather than marking a PT page as not modified 
to trick the pagedaemon into freeing it later, just unmap the page
and free it immediately.  fixes PR 7337.
 1999-04-22 04:24:52 +00:00
simonb 6f6573cb10 Move BOOTINFO_ADDR up to 0x8001fc00, and reduce the maximum size of a 
bootinfo record to 1kB (we are using less than 200 bytes now) so that it
doesn't run into addition PROM memory.

At 0x8001f00 the bootinfo record was stomping on some memory used by the
SFB cards for font information.

simonb 25715bb0f2 Comment out 'config nfsnetbsd'. 1999-04-21 12:53:56 +00:00
scottr 136972df3a Actually, the last change solved a different but related problem than 
the one mentioned in PR 7376.  By clearing the display in iteon()
instead, we can kill both birds with the same stone.
 1999-04-21 06:00:07 +00:00
scottr 48ff49fee0 When attaching the ite console, clear the entire display rather than assuming 
that the emulator will do it for us.  (The emulator will only clear
full character-sized rows.)  Incidentally fixes PR 7376.
 1999-04-21 05:18:17 +00:00
simonb 24323d7ef4 In cpu_startup(): 
+ Initialise minaddr to the start of the file I/O buffers.
 + Check for overallocation of RAM for these buffers.
 + Change function name in panic message to match reality.

Code taken from almost every other port, and fixes the:
   uvm_km_suballoc: unable to allocate space in parent map
panic that some people have been experiencing.
 1999-04-21 02:03:24 +00:00

thorpej f7b0fea081 After reviewing the Green Book, BPT traps do indeed leave the PC pointing 
to the instruction _after_ the `call_pal bpt' instruction.

thorpej 375b3fa699 Prototype alpha_debug(), and add some definitions for KGDB. 1999-04-20 21:23:56 +00:00
thorpej 62d09f4f93 Move the inclusion of <machine/bus.h> to within a _KERNEL section. 1999-04-20 21:23:09 +00:00
thorpej 869951571d - Clean up ddb_trap() somewhat, and handle exceptions that happen while we're 
in DDB (e.g. if a bad pointer was dereferenced; the debugger will recover).
- Change a comment to indicate that we are on the debugger stack when we get
  to ddb_trap().
- Fix possible buglet in computation of the branch target in db_branch_taken().
 1999-04-20 21:19:48 +00:00
thorpej 701edb8db8 - Revert previous, and do debugger entry if kernel BUGCHK or BPT traps 
happen.  If the debugger doesn't handle the trap, arrange things so the
  debugger won't be called again before we panic.
- Before panic'ing, give the debugger a chance to field the trap, and
  if the debugger has handled things, allow the kernel to continue running,
  like the i386 port does.
 1999-04-20 21:16:59 +00:00
thorpej a12dedc3ea - Revert previous change to XentIF(), now that we're going to enter the 
debugger differently.
- Pull in debugger glue if DDB is configured.

And one unrelated change, while I was here: Don't create a fake trapframe
for main(); it hasn't been used by main() for quite some time, and panic
if main() returns, because that's not supposed to happen now.
 1999-04-20 21:11:59 +00:00
thorpej 1b2eac076f Add a common debugger entry point, alpha_debug(), which performs various 
tasks (i.e. switches to the debug stack) and then invokes the appropriate
debugger (DDB or eventually KGDB).
 1999-04-20 21:09:49 +00:00
thorpej 9d78593b30 Back out previous; we're going to dispatch to the debugger differently. 1999-04-20 21:08:23 +00:00

mark 7c3542d098 Add the rnd pseudo device. 1999-04-20 09:30:08 +00:00
mark 902004cefc Don't try and calculate the time in microtime() unless cpu_initclocks() 
has already been called and thus we know the values the timers are using.
This also ensures that clock_sc will always be valid when we try and use
it to read the timer registers.
