Split code to handle on-chip rtc into a separate driver
Eliminate all todr code from clock.c
Move __HAVE_GENERIC_TODR to sh3/include/types.h
Somehow I managed to forget to commit mmeye changes.

schemas. Disk information and disk geometry are designed to replace
information currently conveyed to user space using struct disklabel.
- Add a dk_info member to struct disk; a reference to a disk information
dictionary. This dictionary is to be allocated and the reference stored
in struct disk by individual drivers.
- disk_detach0() will release dk_info if non-NULL.
- Convert the wd(4) driver to stash geometry and other disk properties
as the "disk-info" property in its properties dictionary. This needs
some cleanup, but will serve as an example of what to do with other
disk drivers.
"execute a command" ioctl that takes a dictionary as an argument
(specifying the command and arguments) and returns a dictionary
with the results (error code, optional error message, optional
result data).
- Define and implement a "get-properties" command for DRVCTLCOMMAND
that returns the properties dictionary of the specified device.
- Add a -p flag to drvctl(8) to fetch and display the properties of
the specified device.
This is a great example of how to use prop_dictionary_sendrecv_ioctl().
plist-based messages and to eliminate looping previously required to
receive a plist from the kernel:
- prop_dictionary_copyin_ioctl() and prop_dictionary_copyout_ioctl()
now take the cmd argument rather than the file open flag. The
read-ness or write-ness of an ioctl command is checked by these
routines to ensure that information is being passed to/from the
userland component properly.
- prop_dictionary_copyout_ioctl() now allocates the memory for the
XML plist on behalf of the userland component by way of uvm_mmap().
The XML plist is copied out to the newly-mapped anonymous region,
and the pointer returned via the plistref.
- prop_dictionary_recv_ioctl() is responsible for munmap()'ing the
region after parsing the XML plist into internal represenatation.
- A new prop_dictionary_sendrecv_ioctl() is added, allowing user space
code to send a dictionary to the kernel and receive one back as a
reply.
Update users of prop_kern for the API changes (Bluetooth).
This constitutes an ABI / protocol change -- but this will also be put
into NetBSD 4.0 so that the first proplib release will implement the new
scheme.
instead of just vnode pointers. Fixes erroneous "does not match mounted
device" errors from mount(8) in the presence of MFS /dev, init.root, &c.
No objections on tech-kern.
echos this "non-error" message (not even tulip.c). Included is an
explanatory message stating that these counters should probably all be
converted to evcnt counters.
to do with the security model used. Move back the call to spec_open(),
which can now return the real return value from vfs_mountedon() (EBUSY)
and not EPERM, changing semantics.
of available test candidates. It uses the previously unused (as far as I
can tell) Timer D, in freerunning mode. It only uses a 1/200 prescaler
(20KHz), as anything faster would roll over too fast for the system timer.
(Gotta love 8-bit resolution timers!) Approved for untested commit by core@.
This gets rid of the now-unneded "todclock" and "todservice" attributes
from the footbridge device files, which should allow netwinder to build
again after its conversion to generic TODR.
Resulting kernel verified to boot up OK on gxemul (after my recent
fixes of the gxemul package to emulate free-running timers).
- add a new entry point for idle called idle_switch that is called by
cpu_switch() in the MP case when sched_whichqs is zero, properly
setting up the idle stack. from petrov@ via martin@.
