Like the previous patch for VX boards, miXart device driver can be also rewritten to use nonatomic PCM ops. Simply spinlocks are replaced with mutex, the tasklet code is merged into the threaded irq handler. Also, now mgr->msg_mutex is superfluous, so merged to msg_lock.

Rewrite VXpocket and VX222 drivers to use the new PCM nonatomic ops. The former irq tasklet is replaced with a threaded irq handler, and the tasklet for the PCM delayed start is simply merged into the normal PCM trigger, as well as the replacement of spinlock with mutex.

Add quirks for XMOS based DACs for native DSD playback support using the new DSD_U32_LE sample format. This version adds native DSD support for: - iFi Audio micro iDSD/nano iDSD (they use the same prod. id) - DIYINHK USB to I2S/DSD converter Changes from v2: - fix and simplify switch statement Changes from v1: - use specific product id and alt setting per XMOS based device [fixed a misc coding style issue by tiwai] Signed-off-by: NJurgen Kramer <gtmkramer@xs4all.nl> Signed-off-by: NTakashi Iwai <tiwai@suse.de>

XMOS based USB DACs with native DSD support expose this feature via a USB alternate setting. The audio format is either 32-bit raw or a 32-bit PCM format. To utilize this feature on linux this patch introduces a new 32-bit DSD sampleformat DSD_U32_LE. A follow up patch will add a quirk for XMOS based devices to utilize the new format. Further patches will add support to alsa-lib. Signed-off-by: NJurgen Kramer <gtmkramer@xs4all.nl> Signed-off-by: NTakashi Iwai <tiwai@suse.de>

The DACs on Sigmatel/IDT codecs do mute at the lowest volume level, and in the earlier drivers, we passed TLV_DB_SCALE_MUTE bit for each volume control element like Speaker and Headphone as well as Master. Along with the translation to the generic parser, however, the TLV bit was lost for the slave controls (e.g. Speaker) but set only to Master. In theory this should have sufficed, but apps, particularly PA, do care the slave volume bits, so we seem to see a regression in the volume controls. This patch adds a flag to hda_gen_spec to specify the DAC mute feature, and adds the TLV bit properly for all relevant volume controls. Also, the TLV bit for vmaster is set in hda_generic.c, so that we can get rid of all tricks from the codec driver side. As the similar hack is applied to Conexant 5051 stuff, we can get rid of it as well. BugLink: https://bugs.launchpad.net/bugs/1357928Signed-off-by: NTakashi Iwai <tiwai@suse.de>

The previous commit for the non-atomic PCM ops added more codes to snd_pcm_stream_lock() and its variants. Since they are inlined functions, it resulted in a significant code size bloat. For reducing the size bloat, this patch changes the inline functions to the normal function calls. The export of rwlock and rwsem are removed as well, since they are referred only in pcm_native.c now. Signed-off-by: NTakashi Iwai <tiwai@suse.de>

Currently, many PCM operations are performed in a critical section protected by spinlock, typically the trigger and pointer callbacks are assumed to be atomic. This is basically because some trigger action (e.g. PCM stop after drain or xrun) is done in the interrupt handler. If a driver runs in a threaded irq, however, this doesn't have to be atomic. And many devices want to handle trigger in a non-atomic context due to lengthy communications. This patch tries all PCM calls operational in non-atomic context. What it does is very simple: replaces the substream spinlock with the corresponding substream mutex when pcm->nonatomic flag is set. The driver that wants to use the non-atomic PCM ops just needs to set the flag and keep the rest as is. (Of course, it must not handle any PCM ops in irq context.) Note that the code doesn't check whether it's atomic-safe or not, but trust in 100% that the driver sets pcm->nonatomic correctly. One possible problem is the case where linked PCM substreams have inconsistent nonatomic states. For avoiding this, snd_pcm_link() returns an error if one tries to link an inconsistent PCM substream.

Merge tag 'trace-fixes-v3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull fix for ftrace function tracer/profiler conflict from Steven Rostedt: "The rewrite of the ftrace code that makes it possible to allow for separate trampolines had a design flaw with the interaction between the function and function_graph tracers. The main flaw was the simplification of the use of multiple tracers having the same filter (like function and function_graph, that use the set_ftrace_filter file to filter their code). The design assumed that the two tracers could never run simultaneously as only one tracer can be used at a time. The problem with this assumption was that the function profiler could be implemented on top of the function graph tracer, and the function profiler could run at the same time as the function tracer. This caused the assumption to be broken and when ftrace detected this failed assumpiton it would spit out a nasty warning and shut itself down. Instead of using a single ftrace_ops that switches between the function and function_graph callbacks, the two tracers can again use their own ftrace_ops. But instead of having a complex hierarchy of ftrace_ops, the filter fields are placed in its own structure and the ftrace_ops can carefully use the same filter. This change took a bit to be able to allow for this and currently only the global_ops can share the same filter, but this new design can easily be modified to allow for any ftrace_ops to share its filter with another ftrace_ops. The first four patches deal with the change of allowing the ftrace_ops to share the filter (and this needs to go to 3.16 as well). The fifth patch fixes a bug that was also caused by the new changes but only for archs other than x86, and only if those archs implement a direct call to the function_graph tracer which they do not do yet but will in the future. It does not need to go to stable, but needs to be fixed before the other archs update their code to allow direct calls to the function_graph trampoline" * tag 'trace-fixes-v3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace: Use current addr when converting to nop in __ftrace_replace_code() ftrace: Fix function_profiler and function tracer together ftrace: Fix up trampoline accounting with looping on hash ops ftrace: Update all ftrace_ops for a ftrace_hash_ops update ftrace: Allow ftrace_ops to use the hashes from other ops

As reported by Dan Aloni, commit f8567a38 ("aio: fix aio request leak when events are reaped by userspace") introduces a regression when user code attempts to perform io_submit() with more events than are available in the ring buffer. Reverting that commit would reintroduce a regression when user space event reaping is used. Fixing this bug is a bit more involved than the previous attempts to fix this regression. Since we do not have a single point at which we can count events as being reaped by user space and io_getevents(), we have to track event completion by looking at the number of events left in the event ring. So long as there are as many events in the ring buffer as there have been completion events generate, we cannot call put_reqs_available(). The code to check for this is now placed in refill_reqs_available(). A test program from Dan and modified by me for verifying this bug is available at http://www.kvack.org/~bcrl/20140824-aio_bug.c .
