when we have a sync pipe whose packets generate interrupts more often.

Clemens Ladisch 8886f33f25 sound: usb-audio: add workaround for Blue Microphones devices
Blue Microphones USB devices have an alternate setting that sends two
channels of data to the computer.  Unfortunately, the descriptors of
that altsetting have a wrong channel setting, which means that any
recorded data from such a device has twice the sample rate from what
would be expected.

This patch adds a workaround to ignore that altsetting.  Since these
devices have only one actual channel, no data is lost.

Added boot quirk for C-Media CM6206 device in snd_usb_audio_probe.
The function snd_usb_cm6206_boot_quirk sets up six internal 16-bit
registers in order to initialize the device. Values for the registers
came from sniffing USB traffic under Windows since only four of the six
are documented in the datasheet for CM106 and some reserved bits were
also being set.

If not passed as module option, provide an own card ID with the newly
introduced snd_set_card_id() call.

This will prevent ALSA from calling choose_default_name() which only
takes the last part of a name containing whitespaces. This for example
caused 'Audio 4 DJ' to be shortened to 'DJ', which was not very
descriptive.

The implementation now takes the short name and removes all whitespaces
from it which is much nicer.

Phillip Michael Jordan b9c196e145 ALSA: snd_usb_audio: fix SB Extigy IR Remote regression
The support for the SB Extigy's remote seems to be broken in all
recent ALSA versions, including 1.0.17. The driver detects the event
correctly, then submits a URB to query the RC code. On the Extigy, the
URB is submitted with a length of 2 bytes. My hardware, however, only
replies with 1 byte, containing the correct RC button code. The
current implementation discards this as being too short. (line 1784 of
usbmixer.c)

This patch specifies a "minimum packet length" in the remote control
configuration. I've left the values for the Audigy 2/Live! the same as
the packet length, as I'm assuming the existing code works with them.
(I don't have the hardware to confirm) This fixes the Extigy RC
support, e.g. for use with Lirc.

Clemens Ladisch d05cc10432 [ALSA] usb-audio: work around broken M-Audio MidiSport Uno firmware
The firmware of the M-Audio USB Uno MIDI Interface has, at least in
hardware revision 1.25, a bug that garbles its USB output.  When it
receives a Note On MIDI message that uses running status, the resulting
USB MIDI packet has a wrong CIN (4 instead of 9) and a wrong length
(2 bytes, the status byte is still missing).
This patch adds a workaround to track the CINs and the MIDI messages of
received USB MIDI packets to detect whether a packet with CIN 4 is a
correct SysEx packet or a buggy running status packet.

David Howells 7d12e780e0 IRQ: Maintain regs pointer globally rather than passing to IRQ handlers
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.

The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around.  On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).

Where appropriate, an arch may override the generic storage facility and do
something different with the variable.  On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.

Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions.  Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller.  A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.

I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.

This will affect all archs.  Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

	struct pt_regs *old_regs = set_irq_regs(regs);

And put the old one back at the end:

	set_irq_regs(old_regs);

Don't pass regs through to generic_handle_irq() or __do_IRQ().

In timer_interrupt(), this sort of change will be necessary:

	-	update_process_times(user_mode(regs));
	-	profile_tick(CPU_PROFILING, regs);
	+	update_process_times(user_mode(get_irq_regs()));
	+	profile_tick(CPU_PROFILING);

I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().

Some notes on the interrupt handling in the drivers:

 (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
     the input_dev struct.

 (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
     something different depending on whether it's been supplied with a regs
     pointer or not.

 (*) Various IRQ handler function pointers have been moved to type
     irq_handler_t.

Pete Zaitcev 38e2bfc94e USB: Dealias -110 code (more complete)
The purpose of this patch is to split off the case when a device does
not reply on the lower level (which is reported by HC hardware), and
a case when the device accepted the request, but does not reply at
upper level. This redefinition allows to diagnose issues easier,
without asking the user if the -110 happened "immediately".

The usbmon splits such cases already thanks to its timestamp, but
it's not always available.

I adjusted all drivers which I found affected (by searching for "urb").
Out of tree drivers may suffer a little bit, but I do not expect much
breakage. At worst they may print a few messages.

There's at least one USB audio chipset out there which supports only one
non-standard rate (ID 0e6a:0310 supports 46875Hz). There's a few other
patches for this card which are unsatisfactory because they attempt to
map this rate to 44.1k leading to sound distortion.
The patch below uses SNDRV_PCM_RATE_KNOT to properly support the
non-standard rates where they are available.

Sam Revitch e217e30c35 [ALSA] usb-audio support for Turtle Beach Roadie
From: Sam Revitch <sam.revitch@gmail.com>Recently a Turtle Beach Audio Advantage Roadie device ended up in my
possession.  It seems to work with the snd-usb-audio driver, but only
using the headphone jack in 2-channel mode.  The device has a DIN
connector carrying six more channels that are otherwise silent.
C-Media has freely available documentation for the CM106 chip around
which this device is based, and enabling 8-channel output, or
6-channel output with the headphone jack following the front pair is a
matter of setting one of its registers.
Attached is a patch to try to enable 5.1 output mode at probe time.
It seems to work correctly with my device.  There is quite list of
other configurables for this device that might deserve controls.
