tasks are modelled on the timeout api, so users familiar with
timeout_set, timeout_add, and timeout_del will already know what
to expect from task_set, task_add, and task_del.
i wrote this because workq_add_task can fail in the place you
actually need it, and there arent any good ways of recovering at
that point. workq_queue_task was added to try and help, but required
external state to be stored for users of that api to know whether
something was already queued or not.
workqs also didnt provide a way to cancel or remove work.
this has been percolating with a bunch of people. putting it in as i
wrote it so i can apply their feedback to the code with the history kept
in cvs.

400 and 4300. Limited to PIO mode only for now, until the DMA controller is
tamed. Heavily based upon the MI aic(4) driver.

interface. VXLAN is a UDP-based tunnelling protocol for overlaying
virtualized layer 2 networks over layer 3 networks. The implementation
is based on draft-mahalingam-dutt-dcops-vxlan-04 and has been tested
with other implementations in the wild.

- the am7990_get() - now lance_get() - is unchanged.
- the interrupt acknowledge logic is unchanged, and will disable interrupts,
then acknowledge all interrupt conditions.
Add ILACC (79900) support (from NetBSD).
Both LANCE (am7990.c) and ILACC (am79900.c) code share as much common code
(lance.c) as possible. This affects all le(4) attachments, but the changes
are mostly mechanical, to split am7990-specific parts from lance-agnostic
parts.
Compile tested on all affected platforms. Tested on alpha, hp300, luna88k,
mvme88k, sparc, sparc64 and vax.

members to 64bit types. Assign new syscall numbers for (almost
all) the syscalls that involve the affected types, including anything
with time_t, timeval, itimerval, timespec, rusage, dirent, stat,
or kevent arguments. Add a d_off member to struct dirent and replace
getdirentries() with getdents(), thus immensely simplifying and
accelerating telldir/seekdir. Build perl with -DBIG_TIME.
Bump the major on every single base library: the compat bits included
here are only good enough to make the transition; the T32 compat
option will be burned as soon as we've reached the new world are
are happy with the snapshots for all architectures.
DANGER: ABI incompatibility. Updating to this kernel requires extra
work or you won't be able to login: install a snapshot instead.
Much assistance in fixing userland issues from deraadt@ and tedu@
and build assistance from todd@ and otto@

Includes kernel modesetting, framebuffer console and support
for newer hardware.
Firmware needs to be present for acceleration and in some cases
modesetting to work. It can be installed via fw_update
or manually via pkg_add.
With lots of help from kettenis@ some macppc bits from mpi@
and some ttm refcount/queue bits from FreeBSD.
Thanks to M:Tier and the OpenBSD Foundation for sponsoring this work.

Also move the onewire_bitbang define to be close to i2c_bitbang since they
are similar.

This card reader does not comply to the standard SDHC interface
supported by sdhc(4) and hence requires a custom driver.
With help from uwe and mikeb. Useful hints were also provided by the
author of the corresponding Linux driver (wwang at realsil com cn),
thanks a lot! Tested by myself and weerd on i386 and amd64.

(IP20, IP22, IP24) in 64-bit mode, adapated from NetBSD. Currently limited
to headless operation, input and video drivers will get ported soon.
Should work on all R4000, R4440 and R5000 based systems. L2 cache on R5000SC
Indy not supported yet (coming soon), R4600 not supported yet either (coming
soon as well).
Tested to boot multiuser on: Indigo2 R4000SC, Indy R4000PC, Indy R4000SC,
Indy R5000SC, Indigo2 R4400SC. There are still glitches in the Ethernet driver
which are being looked at.
Expansion support is limited to the GIO E++ board; GIO boards with PCI-GIO
bridges not ported yet due to the lack of hardware, and this kind of driver
does not port blindly.
Most of this work comes from NetBSD, polishing and integration work, as well
as putting as many ``R4x00 in 64-bit mode'' erratas as necessary, by yours
truly.
More work is coming, as well as trying to get some easy way to boot install
kernels (as older PROM can only boot ECOFF binaries, which won't do for the
kernel).

no oks (it is really a pain to review properly)
extensively tested, I'm confident it'll be stable
'now is the time' from several icb inhabitants
Diff provides:
- ability to specify different allocators for different regions/maps
- a simpler implementation of the current allocator
- currently in compatibility mode: it will generate similar addresses
as the old allocator

Many thanks to Marco Peereboom for his assistance with testing and
debugging. Thanks also to Josh Grosse and Chris Jackman for testing.

(hp300) and the HP9000/705 and 9000/710 (hppa). 8-bit mono, 8KHz, no surprise
since it is based upon a digital phone chip.
Tested on 425e only so far, and playback only; configured in, but disabled,
on hppa kernels until there are positive test reports (I am not sure the
interrupt assignment on hppa is correct).
And now people no longer can joke about audio on hp300.

in DIO-II space, as a fat device spanning four select codes (i.e. 16MB of
memory). This is way too much for an at-most 2 Mpixel 8bit frame buffer, and
it turns out that this is because the device provides both a regular DIO-II
frame buffer (spanning two select codes) and a regular STI frame buffer
(spanning the other two select codes).
This commit introduces a straightforward sti@dio attachment to get a working
sti(4) and wsdisplay(4) in a ridiculously small number of lines; however
the console code needs some changes to avoid duplicating globals.
While there, add sti@dio support for the bootblocks, and I couldn't help
myself but clean the most rotten parts of them, and try to have them reuse
various files in sys/arch/hp300/dev instead of rolling their outdated ones.
Tested on a real 382 with the low-resolution frame buffer:
sti0 at dio0 scode 132: rev 8.02;129, ID 0x27134CB440A00499
sti0: 382V, 2048x512 frame buffer, 640x480x8 display
sti0: 8x16 font type 1, 16 bpc, charset 0-255
wsdisplay0 at sti0 mux 1: console (std, vt100 emulation)
Boot blocks updates tested on DIO-II 425t (serial/glass console), SGC 425e
(serial/glass console) and 382 (serial/glass console). And will be tested
on SGC 425t soon as well.

code. Missing chunks of the API are imported from the libc version,
with a few #ifdef's to port it into the kernel environment.
The bootblocks already used the newer code, and should encounter no
surprises since there are so few changes to the existing files. In
the kernel, ipcomp and kernel ppp are changed to the new API.
ipcomp has been tested.
