a newly introduced struct ofw_bus_devinfo which can hold the OFW info
of a device recallable via the ofw_bus KOBJ interface. Introduce a set
of functions ofw_bus_gen_get_*() which use ofw_bus_default_get_devinfo()
to provide generic subroutines for implementing the rest of the ofw_bus
KOBJ interface in a bus driver.
This is inspired by bus_get_resource_list() and bus_generic_rl_*_resource()
and allows to reduce code duplication in bus drivers as they only have
to provide an ofw_bus_default_get_devinfo() implementation in order to
provide the ofw_bus KOBJ interface via ofw_bus_gen_get_*().
- While here add a comment to ofw_bus_if.m describing the intention of
the ofw_bus KOBJ interface.

The following repo-copies were made (by Mark Murray):
sys/i386/isa/spkr.c -> sys/dev/speaker/spkr.c

share/man/man4/man4.i386/spkr.4 -> share/man/man4/spkr.4
nearly identical to wintel/ia32, with a couple of tweaks. Since it is
so similar to ia32, it is optionally added to a i386 kernel. This
port is preliminary, but seems to work well. Further improvements
will improve the interaction with syscons(4), port Linux nforce driver
and future versions of the xbox.
This supports the 64MB and 128MB boxes. You'll need the most recent
CVS version of Cromwell (the Linux BIOS for the XBOX) to boot.
Rink will be maintaining this port, and is interested in feedback.
He's setup a website http://xbox-bsd.nl to report the latest
developments.
Any silly mistakes are my fault.

- remove pmap.c
- add mmu_if.h, mmu_oea.c, pmap_dispatch.c
powerpc/include/mmuvar.h
- definitions for MMU implementations
powerpc/include/pmap.h
- remove pmap_pte_spill declaration
- add pmap_mmu_install declaration
- size the phys_avail array
- pmap_bootstrapped is now global-scope
powerpc/powerpc/machdep.c
- call kobj_machdep_init early in the boot sequence to allow
kobj usage prior to SI_SUB_LOCK
- install the OEA pmap code. This will be moved to CPU-specific
init code in the future.
powerpc/powerpc/mmu_if.m
- Kobj MMU interface definitions
powerpc/powerpc/pmap_dispatch.c
- central dispatch for pmap calls
- contains the global mmu kobj and the routine to locate the
the mmu implementation and init the kobj

(typically people giving me a hard time for it). Since all that was
added to config was nocpu, and since we don't use it, we don't need to
bump the version.

Retire the old i386-only pcf driver, and activate the new general

been developing all this on).

our kernel linker will only load PT_LOAD segments, apparently not.
Instead, produce .dbg objects from .debug objects, and install
them together with non-debug objects, as described in objcopy(1).
Original code by: obrien
Try to make everyone happy: David (to have debug kernels installed
by default), Warner (to be able to override that), and myself (for
actually making it all work and to be consistent).
Now, if kernel was configured for debugging (through DEBUG=-g in
the kernel config file or "config -g"), doing "make install" will
install debug versions of kernel and module objects with their
canonical names,
kernel.debug -> /boot/kernel/kernel
if_fxp.ko.debug -> /boot/kernel/if_fxp.ko
Installing a kernel not configured for debugging, or debug kernel
with INSTALL_NODEBUG variable defined, will install non-debug
kernel and module objects.
Also, restore the install.debug and reinstall.debug targets that
are part of the existing API (they cause some additional gdb(1)
scripts to be installed).
be installed. It should have been optional to install a non-debug
one, just like it was formerly optional to install a debug one. In
order to do that, most of 1.84 had to go.
Instead, make installing the debug kernel the default, but create a
new option INSTALL_NODEBUG for those people that have small /
partitions and good source control habits.
This preserves the behavior of 1.84 while allowing it to be overriden
for people (like me) that do not have the time to upgrade to get a
bigger / and also don't have time for stupid makefile tricks when
upgrading their older system, but still want a kernel.debug around if
things go south.
IPI_STOP IPIs.
- Change the i386 and amd64 MD IPI code to send an NMI if STOP_NMI is
enabled if an attempt is made to send an IPI_STOP IPI. If the kernel
option is enabled, there is also a sysctl to change the behavior at
runtime (debug.stop_cpus_with_nmi which defaults to enabled). This
includes removing stop_cpus_nmi() and making ipi_nmi_selected() a
private function for i386 and amd64.
- Fix ipi_all(), ipi_all_but_self(), and ipi_self() on i386 and amd64 to
properly handle bitmapped IPIs as well as IPI_STOP IPIs when STOP_NMI is
enabled.
- Fix ipi_nmi_handler() to execute the restart function on the first CPU
that is restarted making use of atomic_readandclear() rather than
assuming that the BSP is always included in the set of restarted CPUs.
Also, the NMI handler didn't clear the function pointer meaning that
subsequent stop and restarts could execute the function again.
- Define a new macro HAVE_STOPPEDPCBS on i386 and amd64 to control the use
of stoppedpcbs[] and always enable it for i386 and amd64 instead of
being dependent on KDB_STOP_NMI. It works fine in both the NMI and
non-NMI cases.
originally wrote it for 4.x and hasn't really had the time to fully update
it to 5.x and later. Also, the author doesn't use the hardware anymore as

After this change it is possible to embrace opt_*.h includes with ifdef
HAVE_KERNEL_OPTION_HEADERS. And thus, avoid editing a lot of Makefiles
