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.

hannken 7de36862a8 Rename bufq_init() to bufq_alloc().
Add bufq_free() to remove a buffer queue.
Avoid MALLOC while holding a spinlock.

hannken 10ff5e6607 Implement a new device buffer queue interface.
One basic struct, a function to setup a queue with a specific strategy and
three macros to put buf's into the queue, get and remove the next buf or
get the next buf without removal.

The BUFQ_XXX interface will be removed in the future.
The B_ORDERED flag is not longer supported.

bouyer 10b49b13b9 In wdc_exec_command(), for data commands, read the status register after
the data transfer. This is mandatory for data out commands (although none are
used for now), and not forbiddend for data in commands. Also record if we
did transfers any data.
May solve kern/16159 by making the probe more robust in face of fake identify.

bouyer 4ca5497111 Allow wd to attach to something else than wdc/pciide (like USB<->ATA bridges):
- move some functions from ata.c to ata_wdc.c or wdc.c.
- add callbacks to struct ata_bustype so that wd.c doesn't call directly
  functions from the lower level driver.

bouyer 4809ad42cb Clean up attach of wd/atapibus:
kill ata_atapi_attach. Change atapibus to use a struct scsipi_channel instead
of ata_atapi_attach as attach arch. Create a ata_device, compatible with
scsipi_channel, to attach wd.

On such adaptors, all transfers are done in polling mode.

drochner 06fc2f85cc Since __HAVE_OLD_DISKLABEL, DISKMINOR(u, p) isn't continuous over "p"
anymore. So we can't pass a range to vdevgone() but have to loop over the
partitions explicitely.
(otherwise the next device unit will be killed)

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.

fvdl d040bd5908 Return error in the case of using ODIOCGDINFO or ODIOCGDEFLABEL when
the number of partitions is > OLDMAXPARTITIONS. This is better
than silently truncating the label (don't want to silently throw
away partitions when using an old disklabel binary on a label with
> 8 partitions). From Enami Tsugutomo.

fvdl e2d1c1f926 Adapt all disk devices in MI directories to handle ODIOC* calls
for ports that have bumped MAXPARTITIONS (and thus define
__HAVE_OLD_DISKLABEL).

augustss 7797648425 Change the initial field in struct ata_atapi_attach and struct scsipi_link
slightly to allow scsibus and atapibus to attach to the same device.
Furthermore, only attach a scsibus when the bus type is BUS_SCSI.

bouyer 26f6c9a9cf - DMA code cleanup: pciide_dma_finish() doesn't stop/unload the current DMA op
if an IRQ was not detected, unless the force flag was given. Use this to
  detect if the IRQ was for us (closer to shared IRQ for controllers which
  don't have their own IRQ handler in pciide.c) and to poll for DMA xfer.
  Also makes the timeout recovery code simpler.
- ATAPI cleanup: don't call controller-specific functions from atapiconf.c
  (wdc_*), so that it's possible to attach an atapibus to something else
  than a wdc/pciide (Hi Lennart :).
  Overload struct scsi_adapter with struct atapi_adapter, defined
  as struct scsi_adapter + atapi-specific callbacks. scsipi_link still points
  to an scsi_adapter, atapi code casts it to atapi_adapter if needed.
  Move atapi_softc to atapiconf.h so that it can be used by the underlying
  controller code (e.g. atapi_wdc.c).
  Add an atapi-specific callback *atapi_probedev(), which probe a drive
  in a controller-specific way, allocate the sc_link and fills in the
  ataparams if needed. It then calls atapi_probedev() (from atapiconf.c)
  to do the generic initialisations and attach the device.
- While I'm there merge and centralise the state definitions in atavar.h.
  It should now be possible to use a common ata/atapi routine to set the
  drive's modes (will do later).

thorpej fc96443d15 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

bouyer 638e1a6958 Improve the downgrade logic:
- If UDMA 2 is failing try UDMA 1 first, it helps in some cases
- downgrade if we get an error in the first 4000 xfers, or if we get
  4 errors in 4000 xfers if the first 4000 went without troubles.

While I'm there commit a local change I have since some time to get my CD
probed: issue a "blanck" IDENTIFY before the one used to detect slave ghosts,
with my drive the first IDENTIFY following a controller reset fails with an
aborted command ...
