- Ffs internal snapshots get compiled in unconditionally.
- File system snapshot device fss(4) added to all kernel configs that
have a disk. Device is commented out on all non-GENERIC kernels.

image. The idea is to keep INSTALL as small as possible (XXXVERBOSE options are
off, no IP filtering, SCSI support etc.) to shoehorn into size limits imposed
by the Cobalt's firmware and to have full-blown GENERIC kernel which uses
NetBSD bootloader anyway.
All those kernels have a line for both tun and bridge, and if either is
commented out, tap is commented out also. With the exception of i386's
GENERIC_TINY.
XXX: we _need_ some way of making this more simple.
which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.
com_mainbus_cninit() and move these cn functions from cobalt/console.c
to dev/com_mainbus.c
- call cninit() only once
- remove unneeded includes
- use ANSI function decls
in cpu_initclocks(9) via a callback function.
Fixes the "hardclock(9) is called before cpu_initclocks(9)" problem
reported by KIYOHARA Takashi on port-cobalt.
- Use bus_space(9) functions to access GT64111 registers and
add register definitions for GT64111 in gtreg.h.
(XXX this could be in sys/dev/marvell?)
- Move microtime(9) from machdep.c to clock.c, and read timer0 register
via a callback function. Also change microtime(9) like other ports
to guarantee that the time will be greater than the value obtained
by a previous call.
to all GENERIC-like kernel config files where SYSV* options were already
present (commented out if the SYSV* options are commented out).
Fix lib/25897 and lib/25898.
RAM a chance to boot. Discussed with soren@, tested on customer's board.
NB: While acceptable as a temporary workaround since most (all?) Cobalt
hardware comes with no less than 16Megs on board, changing a kernel load
address or making a boot loader relocatable could be a better solution.
files for machines I know to have genuine PCI slots. As sent to tech-kern
for feedback in December 2003. Based on feedback, opencrypto is commented
out in the macppc GENERIC (due to absense of GENERIC_SOFTINT support),
and added to the sparc64 config (sys/arch/sparc64/conf/GENERIC32).
virtual memory reservation and a private pool of memory pages -- by a scheme
based on memory pools.
This allows better utilization of memory because buffers can now be allocated
with a granularity finer than the system's native page size (useful for
filesystems with e.g. 1k or 2k fragment sizes). It also avoids fragmentation
of virtual to physical memory mappings (due to the former fixed virtual
address reservation) resulting in better utilization of MMU resources on some
platforms. Finally, the scheme is more flexible by allowing run-time decisions
on the amount of memory to be used for buffers.
On the other hand, the effectiveness of the LRU queue for buffer recycling
may be somewhat reduced compared to the traditional method since, due to the
nature of the pool based memory allocation, the actual least recently used
buffer may release its memory to a pool different from the one needed by a
newly allocated buffer. However, this effect will kick in only if the
system is under memory pressure.
on "make depend". Tested on my RaQ2, and fixes port-cobalt/23711.
While here, two more cosmetics:
- remove redundant definitions
- use NOMAN rather than setting MAN empty
