with volatile. The bug didn't show its face until more agressive
optimization showed up, apparently a result of the last egcs upgrade.
(The interrupt handling changes from June have certainly also played
a part.) Thanks to Ken'ichi Ishizaka for discovering the problem.
remove GENERIC.v6 file (as it is part of GENERIC now).
"faith" interface is commented out by default as it is not really for
general use.
IPsec items are commented out as well, though we can enable "options IPSEC"
without export-related issue ("options IPSEC" will enable authentication
portion only). We may need to think about it again.
if you have problem compiling with INET6 on archs I do not have access to,
please contact me.
XXX what to do with arch/arm32/SHARK{,.v6}?
to allow this exception so that accurate tuning of delay() can be
done (i.e. avoiding VIA-related wait states and cache effects as
much as possible).
XXX During this narrow window, it is still conceivable that we could
get interrupts from devices other than the VIA timer. Normally this
shouldn't be a problem because interrupt handlers should generally
not be registered until we get to autoconfig. It is, however, a
potential pitfall to be aware of.
any longer, we can finally avoid enabling interrupts until the
end of cpu_configure(). This resolves a long-standing issue that
has caused us trouble several times in the past.
anything that might cause an interrupt (e.g. the SCSI bus reset in
ncr53c9x_attach()). If we don't do this, the initial interrupt is
lost, thus causing the state machine to never enter IDLE state, thus
causing SCSI commands to never be executed.
Fixes kern/8544, reported by Erik Bertelsen <erik@mediator.uni-c.dk>.
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.
- 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. :)
- 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.
- 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.
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().
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.
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.
