gpioow(4), attaching a bit-banging driver via a GPIO pin. Also,
owtemp(4) which supports some of the 1-Wire temperature sensors, including
the DS18b20 and DS1920 - temperatures are returned via the envsys(4)
framework.
Original drivers by Alexander Yurchenko (grange@openbsd), with envsys(4)
support and a fix to the 1-wire search algorithm (for discovering
devices on the bus) by me.
As discussed on tech-kern earlier this week.
Use the opt_ah.h for the provided HAL to get options like AH_REGOPS_FUNC.
Add AH_REGOPS_FUNC to a few opt_ah.h that don't have it in this version
of the HAL but need it. (The next version from Sam should have this fixed
in it. If it doesn't, then we'll have to take care at import time.)
Ultimately, this should make future imports even easier, and individual ports
should not have to worry about whether AH_REGOPS_FUNC is properly defined or
not, since the opt_ah.h will just take care of it automatically.
Ok'd by dyoung@.
the rules due to needing to conditionally postprocess the HAL object file.
Macppc needs a a non-ELF HAL (EABI) object, so take care of that by default
in the atheros include file.
of digital video recorders popular in Europe and Australia.
These devices have a USB client port which can be used to upload and
download recordings (and other files, such as MIPS binaries for execution
on the DVR's CPU) to/from their internal hard disk, in addition to some
other operations on files and directories.

The new layout almost precisely matches FreeBSD, and should make
future imports much easier.
At the same time, import the current 0.9.16.16 HAL from FreeBSD. According
to sam@, this is the proper version we should be using.
and always call the simple_* locking functions. the locking functions
are compiled out if they are not needed anyway, so a separate option
for this doesn't gain anything.
this also fixes the serial console on my alpha ES40 (which doesn't make much
sense since the com driver should still be under the big lock on alpha,
but whatever).
get this makefile to execute the mkdep commands - no need for a submake
and xargs at that point.
However we do need to do something to stop the 'mkdep -d' and CLEANDEPEND
command lines being to long.
Note that 'echo ${xxx} | cmd' is ok because echo is a shell builtin, and
isn't (usually) subject to the kernel's command line limits.
an overflow occurs.
. Make this error a fatal build time error
. Move the support for dbsym into the MI Makefile.kern.inc,
conditional upon the SYMTAB_SPACE option being defined in
the kernel config file.
- rather than embedding bufq_state in driver softc,
have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
from sys/bufq.h to sys/bufq_impl.h.
(is it better to move it to kern/ or somewhere?)
- fix some obvious breakage in dev/qbus/ts.c. (not tested)
