In the single_cmd mode, the hardware cannot store the multiple replies
like on RIRB, thus each verb has to sync and wait for the response no
matter whether the return value is needed or not.  Otherwise it may
result in a wrong return value from the previous verb.

In the single_cmd mode, the current driver code doesn't do any update
for RIRB just for any safety reason.  But, actually the RIRB and
single_cmd mode don't conflict.  Unsolicited events can be delivered
even while using the single_cmd mode.

This patch allows the handling of unsolicited events with single_cmd
mode, just always checking RIRB independent from single_cmd flag.

When a codec communication error occurs, the CORB/RIRB counters should

The PCI entries of Creative with HD-audio class can be the devices
with emu20k1/emu20k2 chips.  These are supported better by snd-ctxfi
driver.  With that driver, the device will mutate from HD-audio to
its native class.

This patch adds a simple ifdef to avoid the conflict of device probe
between snd-hda-intel and snd-ctxfi drivers.  1102:0009 seems still
OK to be added as it has no emu20kx chip, and is a pure HD-audio

The current error-recovery scheme for the codec communication errors
doesn't work always well.  Especially falling back to the
single-command mode causes the fatal problem on many systems.

In this patch, the problematic verb is re-issued again after the error
(even with polling mode) instead of the single-cmd mode.  The
single-cmd mode will be used only when specified via the command
option explicitly, mainly just for testing.

I found two issues with ICH7-M (it should be related to other HDA chipsets
as well):

- the ring buffer position is not reset when stream restarts (after xrun) -
  solved by moving azx_stream_reset() call from open() to prepare() callback
  and reset posbuf to zero (it might be filled with hw later than position()
  callback is called)
- irq_ignore flag should be set also when ring buffer memory area is not
  changed in prepare() callback - this patch replaces irq_ignore with
  more universal check based on jiffies clock

ASUS W5F needs the fixed codec-slots to probe to override the BIOS
problem.

Tested-by: Giovanni Moser Frainer <giovanni@redix.com.br>
Signed-off-by: Takashi Iwai <tiwai@suse.de>

Some devices have broken BIOS and they don't set the codec probe-bit
properly after cleared by the driver.  This makes the driver skipping
the necessary codec slots.

Since BIOS update isn't always easy, now the semantics of probe_mask
option is changed a bit.  When it contains the bit 8 (0x100), the
lower bits are used to probe that slots regardless of codec-probe bits
returned by the hardware.

For example, probe_mask=0x103 will force to probe the codec slot #0
and #1.

snd-hda-intel driver used schedule_work() fot the delayed DMA pointer
updates, but this has several potential problems:
- it may block other eventsd works longer
- it may deadlock when probing fails and flush_scheduled_work() is
  called during probe callback (as probe callback itself could be
  invoked from eventd)

This patch adds an own workq for each driver instance to solve these
problems.

Added probe_only module option to hd-audio driver.
This option specifies whether the driver creates and initializes the
codec-parser after probing.  When this option is set, the driver skips
the codec parsing and initialization but gives you proc and other
accesses.  It's useful to see the initial codec state for debugging.

The default of this value is off, so the default behavior is as same
as before.

When an error occurs during the codec probing, typically accessing to an
non-existing codec slot, the controller chip gets often screwed up and
can no longer communicate with the codecs.

This patch adds a preparation phase just to probe codec addresses before
actually creating codec instances.  If any error occurs during this
probing phase, the driver resets the controller to recover.

This will (hopefully) fix the famous "single_cmd" errors.
