[ALSA] Fix the wrong sign of format data entries

PCM Midlevel
Fix suggested by Benjamin Herrenschmidt <>

On architectures like PPC, char is handled as 'unsigned char', thus the
pcm_format_data table entries with -1 give a positive 255. This causes
Oops with OSS-emulation on such architectures.

The patch simply adds the right signed/unsigned prefix to fix this problem.

[ALSA] hwdep interface for pcm data

Implements 'rawusb' pcm data transfer through hwdep interface:
The usb_hc moves pcm data from/into memory via DMA.
That memory is mmaped by jack's usx2y driver.
Jack's usx2y driver is the first/last executable code to read/write pcm data.
Read/write is a combination of power of 2 period shaping and float/int

Compared to standard alsa/jack we leave out power of 2 period shaping
inside snd-usb-usx2y which needs memcpy() and additional buffers.
As a side effect possible unwanted pcm-data coruption resulting of
standard alsa's snd-usb-usx2y period shaping scheme falls away.
Result is sane jack operation at buffering schemes down to 128frames,
2 periods.

Also changed Kconfig file, so snd-usb-usx2y is only available for X86,
PPC or ALPHA platforms, as on others DMA-memory isn't mmapable.

[ALSA] fix parsing of mixer unit descriptors

USB generic driver
MU descriptor parsing code completely rewritten; the old code confused

channels. Furthermore, check all bmControls bits so that mixer

a control.

[ALSA] removes unneeded spin_lock_irqsave()s from snd-es1968

ES1968 driver
spin_lock_irqsave(&chip->reg_lock) was called a second time in sequence from
snd_es1968_bob_start() called from es1968_measure_clock().
While this didn't cause harm on my UP laptop with mainline kernels,
it made 'insmod snd-es1968' hang on kernel 2.6.9-mm1-RT-V0.6.9.
The patch assumes that 2 callpaths don't need explicit spinlock protection:
1: The trigger callback, because it is called with IRQs disabled.
2. PM's suspend/resume callbacks, because those are called while ortdinary
user processes are frozen.
Thus the spin_lock_irqsave(&chip->reg_lock) calls in snd_es1968_bob_start()
/ snd_es1968_bob_stop() are not needed.
