external buffer for the PC card connected to the channel. This hack
makes pcmcia cards "being used" at the boot time (by WinCE or NetBSD)
correctly detected. A machine running with root on NFS can now be
properly rebooted.
reversed order.
When you boot with two CF cards inserted, this options makes the one
in the "memory only" slot (channel 1), which is almost always the card
with the NetBSD install, attached as wd0.
Unlike using fixed unit numbers in the kernel config, if you boot with
only a single CF card, that single card will still be wd0 regardless
of which slot it is inserted in.

a more verbose description of why this option is convenient for most
usage patterns.
Use CONFIG_HOOK_POWERCONTROL_LCDLIGHT to turn on/off the LCD in
response to WSDISPLAYIO_SVIDEO.
Implementation of these hooks for Jornada 680 is to follow shortly.
copyin() or copyout().
uvm_useracc() tells us whether the mapping permissions allow access to
the desired part of an address space, and many callers assume that
this is the same as knowing whether an attempt to access that part of
the address space will succeed. however, access to user space can
fail for reasons other than insufficient permission, most notably that
paging in any non-resident data can fail due to i/o errors. most of
the callers of uvm_useracc() make the above incorrect assumption. the
rest are all misguided optimizations, which optimize for the case
where an operation will fail. we'd rather optimize for operations
succeeding, in which case we should just attempt the access and handle
failures due to insufficient permissions the same way we handle i/o
errors. since there appear to be no good uses of uvm_useracc(), we'll
just remove it.
This only turns off the display in the LCD controller.
TODO: Need to add a platform specific way to turn the screen on and
off as well (e.g. on Jornada 680 this is bit 0 in hd64461 GPIO port B).
This driver ignores i/o window handle, but most 'at pcmcia'
attachments init their sc_io_window to -1 and then check at detach
time if it was changed from the "bad" value. Keep them happy, so that
they can correctly clean up when card is detached.

This makes same row chords work properly, most importantly
Ctrl-@, Ctrl-W, Ctrl-S, Ctrl-Alt-F1 (ctrl row), Ctrl-Alt-F3 (alt row).
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
- implement SIMPLEQ_REMOVE(head, elm, type, field). whilst it's O(n),
this mirrors the functionality of SLIST_REMOVE() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE()
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
- remove notes about SIMPLEQ not supporting arbitrary element removal
- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed
- other minor cleanups
indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.
