and large page support. This version is a bit more intelligent about
how it deals with kernel text pages.
Now that this is fixed, don't map the kernel text read-write if
DDB is configured.
- Return FALSE if the PTE does not have PG_V set (previously, you would
get always get true of the PDE was valid, even if the PTE was not).
- Teach it about 4MB pages.
in the non-MULTIPROCESSOR case (LOCKDEBUG requires it). Scheduler
lock is held upon entry to mi_switch() and cpu_switch(), and
cpu_switch() releases the lock before returning.
Largely from Bill Sommerfeld, with some minor bug fixes and
machine-dependent code hacking from me.
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.
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.
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.
This is what Linux pcmcia-cs-3.1.19 does by default.
This fixes unconfigured pccbb interrupt problem of

- 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.
Avoid interpreting the upper 32 bits of 64-bit BARs as a 32-bit BAR.
Otherwise, the code would assume that the value 0 was incorrect and either:
(a) [on bus 0] "fix up" the address to some nonzero value, thus placing
the decoded address range outside of 32-bit address space, or
(b) [elsewhere] completely disable the device.
The fact that this behaviour depends on the bus number of the device is
already XXX'd.
XXX: This will need revisiting if and when we ever want to handle a PCI bus
XXX: with more than 32 bits of address space on an i386.
The onboard Adaptec 7890 on my Dell Precision Workstation 410 works again.
- Use PCI_INTERRUPT_PIN_MAX and I386_PCI_INTERRUPT_LINE_NO_CONNECTION
instead of magic number.
the Following changes are
{Modified with,Approved by} UCHIYAMA Yasushi <uch@netbsd.org>:
- Do not touch a PIRQ router, if the PIRQ is already routed
by the BIOS, or no appropriate IRQ is found for the PIRQ.
The latter prevents a panic on the machine of Frank van der Linden.
- Do not modify a PCI Interrupt Configuration register,
if it is already set by the BIOS, even if it is inconsistent
with the PCI IRQ routing table provided by the BIOS.
(The PCI Interrupt Configuration register seems to be more reliable
than the PCI IRQ routing table.)
This is needed to prevent a incorrect header_fixup() caused
by the incorrect PIR table on a Panasonic Let's Note AL-N2T516J5.
Provide "options PCIBIOS_INTR_FIXUP_FORCE" to retain
previous behavior, i.e. believe the PCI IRQ routing table
and ignore the PCI Interrupt Configuration register.
Although I'm not sure this is really needed.
- Do not modify a PCI Interrupt Configuration register,
if appropriate IRQ is not found for the link.
- Move a pciintr_icu_getclink() call and a pciintr_icu_get_intr()
call from pciintr_link_fixup() to pciintr_link_alloc(),
and only allocate pciintr_link_map if those calls succeeded.
This reduces number of calls of pciintr_icu_getclink(),
and also avoid necessity to validate a clink value in
ICU's {get,set}_{intr,trigger}() functions.
The sanity checks are not removed yet, though.
- Fix uninitialized usage of variable `bitmap' on stage 3
of pciintr_link_fixup().
- Remove a member variable `old_irq' from struct pciintr_link_map.
- Always use 0x%02x for printf format of canonical link value.
- Use DIAGNOSTIC instead of PCIINTR_DEBUG for really weird situation.

broken/fragile. Unlikely to be of much use, and confuses new users
when their system crashes when they, or their dhclient stumble over
it. See kern/10500, kern/8994 for the gory details.
* put #includes of opt headers and headers to get protos used by
net/netisr_dispatch.h in net/netisr.h (if !defined(_LOCORE)) (rather than
in netisr_dispatch.h itself, and potentially nowhere, respectively).
* require netisr.h to be included before netisr_dispatch.h.
* minor additional cleanup of both netisr.h and netisr_dispatch.h.
* clean up uses to remove now-unnecessary header file inclusions, and
local prototypes of the fns.
* convert netisr dispatch implementations which didn't use
netisr_dispatch.h (pc532) to use it.
- for sizeof(void *) == 8 arch, this is mandatory. MHLEN is too small
already (less than 80) and there are chances for unwanted packet loss due
to m_pullup restriction.
- for other cases, the change should avoid allocating clusters in most cases
(even when you have IPv4 IPsec tunnel, or IPv6 with moderate amount of
extension header)
portmasters: if your arch chokes with the change (high memory usage or
whatever), please backout the change for your arch.

"off_t" and the return value is a "paddr_t" to allow mappings

only changed the offset to a "vm_offset_t".

such as the LM78 and VT82C686A (and eventually ACPI). Multiple
sensor devices can be hooked registered with `sysmon', and eventually
sysmon will also handle hardware (and software) watchdog timers.
Convert the `lm' and `viaenv' drivers to the new interface.
from devices connected to pckbc:
- Do actual sample collection in pckbc.
- Add rndsource_element_t to the slot data.
- Change pckbc_set_inputhandler() to take an additional argument,
the name of the device, which is (eventually) passed into
rnd_attach_source() to identify the source.
- Change callers of pckbc_set_inputhander() appropriately.
If __HAVE_CPU_TIMESTAMP is defined, <machine/rnd.h> exists and defines
two functions:
1) u_int32_t cpu_timestamp(void);
returns the 32 low order bits of a reasonably high frequency counter.
2) int cpu_havetimestamp(void);
returns non-zero if cpu_timestamp() actually works.
The timestamp counter should run at a frequency greater than 1 MHz
(otherwise, microtime would be sufficient); other than that, the exact
frequency and origin of the counter are unspecified.
