Markus Grabner 0ca5488806 staging: line6: separate handling of buffer allocation and stream startup
There are several features of the Line6 USB driver which require PCM
data to be exchanged with the device:
*) PCM playback and capture via ALSA
*) software monitoring (for devices without hardware monitoring)
*) optional impulse response measurement
However, from the device's point of view, there is just a single
capture and playback stream, which must be shared between these
subsystems. It is therefore necessary to maintain the state of the
subsystems with respect to PCM usage. We define several constants of
the form LINE6_BIT_PCM_<subsystem>_<direction>_<resource> with the
following meanings:
*) <subsystem> is one of
-) ALSA: PCM playback and capture via ALSA
-) MONITOR: software monitoring
-) IMPULSE: optional impulse response measurement
*) <direction> is one of
-) PLAYBACK: audio output (from host to device)
-) CAPTURE: audio input (from device to host)
*) <resource> is one of
-) BUFFER: buffer required by PCM data stream
-) STREAM: actual PCM data stream

The subsystems call line6_pcm_acquire() to acquire the (shared)
resources needed for a particular operation (e.g., allocate the buffer
for ALSA playback or start the capture stream for software monitoring).
When a resource is no longer needed, it is released by calling
line6_pcm_release(). Buffer allocation and stream startup are handled
separately to allow the ALSA kernel driver to perform them at
appropriate places (since the callback which starts a PCM stream is not
allowed to sleep).

Markus Grabner 6b02a17ee5 staging: line6: fixed ALSA/PCM interaction
The PCM subsystem in the Line6 driver is mainly used for PCM playback and
capture by ALSA, but also has other tasks, most notably providing a
low-latency software monitor for devices which don't support hardware
monitoring (e.g., the TonePort series). This patch makes ALSA "play nicely"
with the other components, i.e., prevents it from resetting the isochronous
USB transfer while other PCM tasks (software monitoring) are running.

Stefan Hajnoczi 665f3f506b staging: line6: wait for urbs in snd_line6_prepare()
The .trigger() pcm callbacks are not allowed to block and cannot wait
until urbs have completed.  We need to ensure that stopping, preparing,
and then restarting a stream always works.

Currently the driver will sometimes return -EBUSY when restarting the
stream because urbs have not completed yet.  This can be triggered by
jackd from userspace.

The solution is to wait on urbs in the .prepare() pcm callback since
blocking is allowed in that callback.  This guarantees that all urbs are
quiesced and ready to be submitted when the start trigger callback is
invoked.

Stefan Hajnoczi 153e38761d staging: line6: eliminate useless index_out variable
Playback urbs use the index_out counter to decide which part of the
playback buffer to use.  Since the urb already has a unique index in
range [0, LINE6_ISO_BUFFERS) there is no need to keep a separate
counter.

Use the urb index instead.  This also eliminates the possibility of two
urbs using the same playback buffer space if they ever complete
out-of-order for some reason.

Stefan Hajnoczi 2f637ee42d staging: line6: fix playback urb transfer buffer calculation
The playback urb transfer buffer calculation does not factor in
LINE6_ISO_PACKETS.  Buffer memory is organized like this in the driver:

  Buffer 0                 Buffer 1                 ...
  [Packet 0, Packet 1, ...][Packet 0, Packet 1, ...][Packet 0, ...]

However, we're lucky that LINE6_ISO_PACKETS is currently defined as 1 so
this patch does not change any behavior.  It's still worth including
this fix in case the LINE6_ISO_PACKETS value is changed in the future.

Stefan Hajnoczi 140e28b83c staging: line6: alloc/free buffers in hw_params/hw_free
It is unsafe to free buffers in line6_pcm_stop(), which is not allowed
to sleep, since urbs cannot be killed completely there and only
unlinked.  This means I/O may still be in progress and the URB
completion function still gets invoked.  This may result in memory
corruption when buffer_in is freed but I/O is still pending.

Additionally, line6_pcm_start() is not supposed to sleep so it should
not use kmalloc(GFP_KERNEL).

These issues can be resolved by performing buffer allocation/freeing in
the .hw_params/.hw_free callbacks instead.  The ALSA documentation also
recommends doing buffer allocation/freeing in these callbacks.

The POD HD300 isochronous endpoints have different max packet sizes for
read and write.  Using the read endpoint max packet size may be too
large for the write endpoint.  Instead we should use the minimum of both
endpoints to be sure the size is acceptable.

In theory we could decouple read and write packet sizes but the driver
currently uses a single size which I chose not to mess with since other
features like software monitoring may depend on a single packet size for
both endpoints.
