mrg 603098b9b5 implement separate read/write disk statistics:
- disk_unbusy() gets a new parameter to tell the IO direction.
	- struct disk_sysctl gets 4 new members for read/write bytes/transfers.
	when processing hw.diskstats, add the read&write bytes/transfers for
	the old combined stats to attempt to keep backwards compatibility.

unfortunately, due to multiple bugs, this will cause new kernels and old
vmstat/iostat/systat programs to fail.  however, the next time this is
change it will not fail again.

this is just the kernel portion.

jdolecek e0cc03a09b merge kqueue branch into -current
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals

kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe

thorpej d1ad2ac4f2 Rather than referencing the cfdriver directly in the cfdata entries,
instead use a string naming the driver.  The cfdriver is then looked
up in a list which is built at run-time.

gehenna 77a6b82b27 Merge the gehenna-devsw branch into the trunk.
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.

bouyer 937a7a3ed9 Pull up the thorpej_scsipi branch to main branch.
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
  ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
  to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
  peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
  recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
  scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
  (no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
  set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
  the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
  will be requeued, or a REQUEST SENSE will be sent as appropriate.

jdolecek 745ab257dc Put back all header files defining ioctls 2001-04-11 19:07:36 +00:00
jdolecek 372e5956ef Only install headers which are actually used by our userland. This
saves about 2.2MB under /usr/include/dev/. Discussed on tech-kern@
recently.

I HOPE to get the list right. The headers I left in are ones
used for MI tools and those whose usage I discovered by grep over tree sources.
Feel free to put needed includes back in if you encounter anything which
should not be removed from lists.

bjh21 fe3273fbb4 Patch from PR kern/8001, submitted by Rafal Boni.
This adds support for EtherExpress/16 cards with 16k of RAM, and in the
process adds general support for PIO mode on these cards.  This entails
changing the way the i82586 driver handles bus barriers, since it doesn't
allow for strange cases like this.

This has been tested on the i386 port with the 'ix' driver in both
16KB (which was the source of the problem) and 32KB modes, as well
as with the 'ef' driver.  I've tested it (briefly) with 'ei' on arm26
as well.  In theory, drivers other than 'ix' should follow precisely the
same code paths as before.

away partitions when using an old disklabel binary on a label with
> 8 partitions). From Enami Tsugutomo.
