a6dd8dc474 Fix AR933x USB support - this needs the same controller initialisation
as the AR7242.

Tested:

* Atheros AP121, AR9331
* ZyDas wifi device, and 64MB (yes, ew) USB flash storage

23dbf8315a Add AP121 ethernet / switch PHY support.
* arge0 is MII
* arge1 is GMII
* the MDIO bus is on arge1, not arge0
* the default switch config is to have ports 0-3 as the switch group,
  with port 4 being an external PHY dedicated to arge0 (ie, 'cpu' port.)

Whilst I'm here, remove unused bits and pieces from the config.

Tested:

* AP121, ping on both arge0 and arge1
* Tested switch port detection using etherswitchcfg

a0315a74fc Now that interrupt driven uart IO is working, flip this back on. 2013-04-05 00:26:29 +00:00

2558987b70 Implement the AR933x interrupt driven UART code.
* Enable RX and host interrupts during bus probe/attach
* Disable all interrupts (+ host ISR) during bus detach
* Enable TX DONE interrupt only when we start transmitting; clear it when
  we're done.
* The RX/TX FIFO depth is still conjecture on my part.  I'll fix this
  shortly.
* The TX FIFO interrupt isn't an "empty" interrupt, it's an "almost empty"
  interrupt.  Sigh.  So..
* .. in ar933x_bus_transmit(), wait for the FIFO to drain before
  continuing.

I dislike having to wait for the FIFO to drain, alas.

Tested:

* Atheros AP121 board, AR9331 SoC.

TODO:

* RX/TX overflow, RX error, BREAK support, etc.
* Figure out the true RX/TX FIFO depth.

eed0ddb40e AR9330/AR9331 also needs to ACK the APB interrupt register, same as
AR724x.

This fixes 'stuck interrupt' problems I was having when writing the
uart interrupt code.

duplicating it three times.
 - Remove extra checks for empty lists of devices and targets on release
since zero refcount check also implies it.
 - Reformat code to reduce indentation.

 - When reference counters are reaching zero, add assertions that there are
no children items left.
 - Add a bit more locking to the xptpdperiphtraverse().

ba9ca7951e Implement AR933x polled IO uart bus code.
This implements the bus transmit/receive/sigchg/ipend methods with
a polled interrupt handler (ipend) rather than enabling hardware
interrupts.

The FIFO is faked at 16 bytes deep for now, just so the transmit
IO side doesn't suck too bad (the callout frequency limits how quickly
IO is flushed to the sender, rather than scheduling the callout more
frequently whilst there's active TX.  But I digress.)

Tested:

* Atheros AP121 (AR9330) reference board, booting to multi-user interactive
  mode.

f23a5f2c03 Fix the busdma logic to work with EDMA chipsets when using bounce
buffers (ie, >4GB on amd64.)

The underlying problem was that PREREAD doesn't sync the mbuf
with the DMA memory (ie, bounce buffer), so the bounce buffer may
have had stale information.  Thus it was always considering the
buffer completed and things just went off the rails.

This change does the following:

* Make ath_rx_pkt() always consume the mbuf somehow; it no longer
  passes error mbufs (eg CRC errors, crypt errors, etc) back up
  to the RX path to recycle.  This means that a new mbuf is always
  allocated each time, but it's cleaner.

* Push the RX buffer map/unmap to occur in the RX path, not
  ath_rx_pkt().  Thus, ath_rx_pkt() now assumes (a) it has to consume
  the mbuf somehow, and (b) that it's already been unmapped and
  synced.

* For the legacy path, the descriptor isn't mapped, it comes out of
  coherent, DMA memory anyway.  So leave it there.

* For the EDMA path, the RX descriptor has to be cleared before
  its passed to the hardware, so that when we check with
  a POSTREAD sync, we actually get either a blank (not finished)
  or a filled out descriptor (finished.)  Otherwise we get stale
  data in the DMA memory.

* .. so, for EDMA RX path, we need PREREAD|PREWRITE to sync the
  data -> DMA memory, then POSTREAD|POSTWRITE to finish syncing
  the DMA memory -> data.

* Whilst we're here, make sure that in EDMA buffer setup (ie,
  bzero'ing the descriptor part) is done before the mbuf is
  map/synched.

NOTE: there's been a lot of commits besides this one with regards to
tidying up the busdma handling in ath(4).  Please check the recent
commit history.

Discussed with and thanks to:	scottl

Tested:

* AR5416 (non-EDMA) on i386, with the DMA tag for the driver
  set to 2^^30, not 2^^32, STA

* AR9580 (EDMA) on i386, as above, STA

* User - tested AR9380 on amd64 with 32GB RAM.

3efd867bfd The code in clear_remove() and clear_inodedeps() skips one entry
in the pagedep and inodedep hash tables. An entry in the table is
skipped because 'pagedep_hash' and 'inodedep_hash' hold the size
of the hash tables - 1.

The chance that this would have any operational failure is extremely
unlikely. These funtions only need to find a single entry and are
only called when there are too many entries. The chance that they
would fail because all the entries are on the single skipped hash
chain are remote.

e241794c89 IFP4 change 222074.
Introduce an explicit close of the output descriptor so that work done
on close is accounted for in the summary output triggered at exit
(implicit close()s occur after atexit() hooks).

This is useful because some devices such as cfi(4) may perform
signficant work after a close occurs (e.g. erasing and rewriting a
block of flash).

c8fe315d98 spa_open_common: fix argument to zvol_create_minors
Prior to r248571 spa_open was always called with a bare pool name,
but now it is called with a dataset name instead (spa_lookup handles
that).
So, when a ZFS root is mounted spa_open is called with a name of a root
dataset, which can very well be different from the pool name.
But zvol_create_minors should be called with the pool name, because it
performs a recursive traversal of all datasets under the name to find
all those that are volumes.
