What we have got:
...
upc0 at iobus0 base 0x010000: config state bb 87 1c 00 00
fdc at upc0 offset 0x3f4 not configured
wdc0 at upc0 offset 0x1f0
lpt0 at upc0 offset 0x278
com0 at upc0 offset 0x3f8: ns8250 or ns16450, no fifo
...
What we haven't got:
- FDC support (found, but not configured).
- Clearing lpt interrupts on arm26 systems (needs help from IOEB).
- A upc(4) manual page.
- More than minimal testing (my A3020s don't have root devices).
- A proper probe routine (arm26 can't use one anyway).
response queue entry). Clean up some of the Fibre Channel completion
stuff so that thing we check actually match the current manual. There's
only one silly lossage that the manual doesn't cover at present- if
an FC command completes with SV (sense valid), the f/w does *not* s
et "GOT_STATUS" in the state bits- I guess they assume that you'd figure
out that if you have SENSE DATA you probably have a CHECK CONDITION. Still-
yet another fine f/w frotz from Qlogic. Add in an ISP_EXEC_THROTTLE
define to set a per-device execution throttle.
The optimized integer formula was supplied by Wolfgang Solfrank on
"tech-kern@netbsd.org". This fixes problems with e.g FreeBSD TV (fxtv),
RealPlayer-7.0 Beta 2 (PR pkg/10818) and KDE's "kscd".
need to access this when we have the proclist locked for reading,
and thus cannot store it in the PCB (which may be swapped out).
As part of this, call pmap_activate() from cpu_switch() to switch
to the new address space, and refresh the PCB's copy of the LDT
selector from the pmap structure (see above paragraph). We need
to do this for MP support anyhow.
Fixes a "panic: spinlock_switchcheck: CPU 0 has 1 spin locks" via
gdt_compact() reported by Nathan Williams.
so that special setup functions needed for some CPUs will be run before
some things (like UVM) are inited.
Add vm_page_zero_enable = FALSE to the cyrix 6x86 case, as page zeroing
while idle causes problems.
I-sync in pmap_remove_mapping() if the old mapping had PG_EXEC, and
kick curcpu (IMB) or other CPUs (via an IPI) only if the pmap was
the kernel pmap or active on other CPUs (curcpu is handled in userret()).
- Use lazy I-sync everywhere, (hopefully) eliminating the last of the
I-sync issues for multiprocessor support.
- Eliminate some memory barriers added in a couple of previous revisions,
after some discussion on port-alpha/tech-smp.
Still some lazy I-sync optimization possibilites:
- pmap_changebit() does not need to I-sync when only write-protecting
a page.
- pmap_asn_alloc() may be able to cancel a pending lazy I-sync when a
new ASN is allocated. Need to double check against Green Book or
Brown Book.

* Fixup the indenting in a few places to conform to NetBSD style

writes (>4k) that are not aligned to incorrectly write 64bytes
of data every 4k interval. This only occurs on raw devices - typically

onintstack to be real integers. Add ISP_ILOCK/ISP_IUNLOCK macros.
Fix the isp_lock/isp_unlock inlines to stop being so embarrassingly
in error. Why, or why, can't I have mutex_enter/mutex_exit, pretty please?
Clarify some startup SCSI mode settings. Insist that the FC f/w options
*must* have ICBOPT_PDBCHANGE_AE set (wasted a half day on this crock).
Make a specific comment in isp_start that the tags being selected for FC
cards, in lieu of any set by the outer layers, are there for safety's sake.
This removes the change from a previous commit.
For the ISP_TOGGLE_TMODE function, do a complete reset, not just an
isp_init (info from Solaris port). Make some cleanup changes for
code clarity.
- manually configure an address from prefix P (like P::1)
- autoconfigure additional address from the same prefix P (like P::ifid).
- rtrequest fails due to P/plen already exists
more fundamental solution should appear later, when kame side stablizes it.

- pmap_zero_page() and pmap_copy_page(): if MULTIPROCESSOR, issue
a memory barrier after we zero/copy the page, to ensure that
other CPUs see the correct data.
- XXX Should we use MB, or is WMB good enough?
Also, bzero -> memset, bcopy -> memcpy.
- Make sure to do an MB after a PTE is set to a new value, so that
other processors see it.
- Use lazy I-sync in two pmap_page_protect() and in pmap_changebit(),
so that it is MP-safe. XXX Two more places where IMB is used in
the raw, but they're not in the common path.
There'll be some more lazy I-sync cleanups soon.
while suspended. When waking up the power hooks are again called at
splhigh() and then the level is lowered.
This prevents interrupts from reaching a device before the power hook
has reinitialized it.
It means that we continously poll USB devices that have a pending transfer
instead of polling just once every ms. This speeds up some transfers
at the expense of using more PCI bandwidth.
driver and make it MI):
Set the ByteSwap bit on big-endian hosts, so we can use 16-bit transfers to get
at packets whatever.
Treat Tx/Rx headers as arrays of four bytes rather than as 32-bit words.
Transmit and receive buffer sizes aren't an intrinsic property of the card,
so they belong in if_ea.c rather than if_eareg.h.
Correct some comments in if_ea.c
rev 1.35 of ip_nat.c checks if packets are too short.
For ICMP packets, this packet length checking double counts
the length of an IP header contained in ICMP messages.
So, unless ICMP packets are long enough (such as echo-reply),
packets are mistakingly considered too short and are dropped.
- Add more delay after reset
- "Big endian mode" on SiS 900 seems broken so don't enable it;
use htole32()/le32toh() instead
- Don't cast u_int16_t array to u_int8_t pointer
- Add some delay() to FILTER_EMIT macro in sip_set_filter()
Now SiS 900 works on my macppc.
Under this option, if only one IRQ is available for the link,
we assumes that the IRQ is already connected, and configure
PCI Interrupt Configuration Register accordingly.

seen when the system is paging and the user runs top/ps/w.

Temperature flags are unaffected- these are still the 'pseudo-thermometers'

- MB_LEN_MAX is increased to 32.
- To ensure binary compatibility for old executables
under multibyte locale, versioned setlocale is added.
- __mb_len_cur definision is added in setlocale.c
and enable it in stdlib.h .
It is also important for multibyte locale stuffs,
but I just forgot.
Because this code is shared, add a macro for bitmask_snprintf() that
should expand to the equivalent snprintf() on non-NetBSD systems. This is
only used in ?HCI_DEBUG cases anyway.
This may happen on machines missing parts of the instruction set (like
some floating point formats).
Only one new instruction added; POLYD, so that the libm assembly files can
be used on architectures missing that instruction.
Also; include emulation code if compile-time option INSN_EMULATE is defined
instead of trying to match on which cputype it is.
N.B. POLYD isn't fully implemented, just enough to make libm happy.
Debugger(). Use db_printf() instead.
This fixes a problem whereby it was impossible to enter the debugger
if the CPU was spinning in lockmgr() for the proclist lock, because
printf() calls logwakeup(), which eventually calls proclist_lock_read(),
which then spins in lockmgr() yet again...
[Note: This change was prematurely committed to the 1.5 branch by
mistake. Since it would've been pulled up anyway, I won't
be sending a pullup request.]
simple locks are held by CPUs. Remove p_simple_locks (which was
unused anyway, really), and add a LOCKDEBUG check for held simple
locks in mi_switch(). Grow p_locks to an int to take up the space
previously used by p_simple_locks so that the proc structure doens't
change size.
NTP is not defined.
Also removes sysctl_ntptime, since that's unreferenced without NTP.
ntp_gettime(2) is left alone, since it doesn't raise SIGSYS, which sys_nosys()
