thorpej 28fb7c1eb8 Define cpu_number() as discussed on tech-smp. 1999-08-10 21:08:05 +00:00
thorpej eb20bbc780 Change the semantics of splsoftclock() to be like other spl*() functions,
that is priority is rasied.  Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.

This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).

XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX.  This platforms still have this bug until their
XXX spl*() functions are fixed.

the hp300 port.

cgd f886376518 be more efficient when doing the SYSTEM_LD_TAIL for -g kernels: don't
copy them just to strip them, use strip -o.

christos 41cc9a0eb8 enable PPP_BSDCOMP, PPP_DEFLATE, PPP_FILTER, PFIL_HOOKS, IPFILTER_LOG

scottr ba0669d0b6 The Quadra 605 and LC 47x apparently share the same logic board,
and hence need the same video hack.  From Ken'ichi Ishizaka.

thorpej 0945bf58b0 Add examples for including the kernel crypto bits from either crypto-us
or crypto-intl, commented out, with instructions to use only one, and
adjust the prefix as necessary.
1999-07-09 18:55:33 +00:00
mrg ecdad0ec33 clean up a bit after jason :)
- fix emitrules() like emitfiles() to deal with the prefix (otherwise it
  would attempt to find the file in the normal base for the NORMAL_C rule).
- add emitincludes() which adds include directives for each prefix to the
  $INCLUDES variable in the makefile.
- add %INCLUDES to each Makefile.arch to deal with the above.

this makes "prefix" actually work in a usable manner, and now i can move
on to fixing compiler warnings (errors) in the ESP code. :)

thorpej 3ebbe095e0 Change the pmap_extract() interface to:
boolean_t pmap_extract(pmap_t, vaddr_t, paddr_t *);
This makes it possible for the pmap to map physical address 0.

itojun 5effafcaa6 kernel configuration for IPv6/IPsec. should be in GENERIC in the future.

briggs 819a054df2 Poll for serial interrupts. Return to 3000us delay instead of 4000us in init. 1999-06-29 04:45:59 +00:00
itojun 427639cdce - Call ip6intr if INET6 is defined.
- remove "need-flag" for mac68k esp driver, as it is not used in anywhere
  and conflicts with IPsec ESP header.

This should be the only MD change in IPv6 support, except kernel config file.
Very sorry if you have any compilation problem with it (I believe it is okay).
If your favorite arch is not included in here, please add a
call to ip6intr() from softintr handle.

briggs 79fe772f46 Include a bit more info about what's not happening with IOP. 1999-06-28 04:33:21 +00:00
briggs 598b09009b Include resourcevar.h for p_limit/rlimit definition. 1999-06-28 04:21:15 +00:00
briggs 71a4446b04 Unfortunately, several changes that are intermingled:
- Add initial IOP support.  ADB doesn't work yet for me, but it's here so
  that others will be encouraged to work on it.  ADB_HW_IOP basically
  is configured as a NOP so that serial consoles will continue to work.
- Roll via1_intr and via2_intr into the intr.c scheme--this also required
  changing rtclock_intr to grovel the stack differently so that hardclock
  gets the right arguments and softclock() doesn't get all reentrant.
- Make via1 interrupts parallel to via2 interrupts--handlers get a pass-
  through pointer and we can register handlers.  Register via1 interrupt
  with intr_establish()--normally level 1, level 6 for A/UX scheme.
- Use intr_establish() to set real via2 interrupt handler instead of the
  hacked function pointer.
- Reorganize adb-direct interrupts so that a function call is removed.
- Implement A/UX interrupts for all Quadras right now.  We may need to
  special case some Quadras, but Linux folks are reporting success on
  several models.
- Fix intrnames to be accurate for the normal, PSC, and A/UX interrupt
  configurations.

briggs f9de07203c Add some constants from Linux/mac68k to note SCC, floppy, and SCSI registers.
Add some code, inspired by Linux/mac68k, to shutdown all DMA on the PSC
at startup and to disable and clear all interrupts except the SCC.

briggs eb7ff0a96f Quadra 900/950 SCC-compatibility serial support is at an offset of 0x20
bytes from the base SCC address.  With this change, serial console works
on my Q950 if the MacOS control panel is used.

thorpej 9e9f068f43 Add the guts of mlockall(MCL_FUTURE). This requires that a process's
"memlock" resource limit to uvm_mmap().  Update all calls accordingly.

thorpej 0288ffb53a pmap_change_wiring() -> pmap_unwire(). 1999-06-17 19:23:20 +00:00
thorpej f5a527bb4e Remove pmap_pageable(); no pmap implements it, and it is not really useful,
because pmap_enter()/pmap_change_wiring() (soon to be pmap_unwire())
communicate the information in greater detail.
1999-06-17 18:21:21 +00:00
thorpej 602d8e81f7 Don't (ab)use uvm_map_pageable() to allocate PT pages. Instead, do
some internal reference counting on PT pages.  We still allocate them
with the page fault routine (a wire-fault, now), but no longer free
PT pages from pmap_pageable().

ender 2b55a690f8 Change the annoying printf() of 2 backspaces to a space followed by a
backspace for aesthetics.

scottr 35f356e920 Eliminate more overhead in delay(); there's no point in doing the same
thing in both the calibrator function and the actual delay function.  At
this point, _delay() does all of the work, so we can garbage collect
dummy_delay() and make _delay() an alternate entry point for delay().

This results in a small (but measurable) improvement on the IIci.

scottr f2f8426e86 Write a new low-level assembly help for delay() and the calibrator. This
eliminates stalls during instruction prefetch and makes the delay
consistent regardless of kernel configuration.

Get Q9x0 dual SCSI at least basically working.
Be paranoid about some register reads.

thorpej d76e7b8c6d Don't pass a nam2blk around at all; just have setroot() and friends reference
dev_name2blk[] directly.  Addresses PR #7622 (ITOH Yasufumi), although
in a different way.

briggs 6e95146ec6 Raise spl4 to spl6 in quick_go--I am now experimenting with interrupts
at levels 5 (sound) and 6 (via1) on the Q700.
Raise splhigh when reading and writing registers.  It's ugly, but it's
possible that we could get an interrupt from a higher-level source,
causing a re-read of a memory location.
This is not good when, e.g., we are reading the interrupt register.
Ideally, we would just raise splhigh() in ncr53c9x_readregs(), but
that's m.i. code, and it may be expensive on other architectures.

briggs 42d2797a4b Comment out DISABLE_EXT_CACHE as it unnecessarily slows down the IIci
w/ external cache.  Leave it around so the paranoid can still use it.

thorpej 2580d306ab Change the vm_map's "entries_pageable" member to a r/o flags member, which
has PAGEABLE and INTRSAFE flags.  PAGEABLE now really means "pageable",
not "allocate vm_map_entry's from non-static pool", so update all map
creations to reflect that.  INTRSAFE maps are maps that are used in
interrupt context (e.g. kmem_map, mb_map), and thus use the static
map entry pool (XXX as does kernel_map, for now).  This will eventually
change now these maps are locked, as well.
