* ALSA: doc: Update option descriptions for snd-usb-audioTakashi Iwai2016-01-291-0/+9

* ALSA: usb-audio: Add quirk_alias optionTakashi Iwai2016-01-291-0/+47
| | | | | | | | | | | | | | | | | | | | | | | This patch adds a new option "quirk_alias" to snd-usb-audio driver for allowing user to pass the quirk alias list. A quirk alias consists of a string form like 0123abcd:5678beef, which makes to apply a quirk to a device with USB ID 0123:abcd treated as if it were 5678:beef. This feature is useful to test an existing quirk, typically for a newer model of the same vendor, without patching / rebuilding the kernel driver. The current implementation is fairly simplistic: since there is no API for matching a usb_device_id to the given ID pair, it has an open code to loop over the id table and matches only with vendor:product pair. So far, this is OK, as all existing entries are with vendor:product pairs, indeed. Once when we have another matching entry, however, we'd need to update get_alias_quirk() as well. Note that this option is provided only for testing / development. If you want to have a proper support, contact to upstream for adding the matching quirk in the driver code statically.

* ALSA: usb-audio: Refer to chip->usb_id for quirks and MIDI creationTakashi Iwai2016-01-295-27/+50
| | | | | | | | | | | | | | | | | | | This is a preliminary patch for the later change to allow a better quirk ID management. In the current USB-audio code, there are a few places looking at usb_device idVendor and idProduct fields directly even though we have already a static member in snd_usb_audio.usb_id. This patch modifies such codes to refer to the latter field. For achieving this, two slightly intensive changes have been done: - The snd_usb_audio object is set/reset via dev_getdrv() for the given USB device; it's needed for minimizing the changes for some existing quirks that take only usb_device object. - __snd_usbmidi_create() is introduced to receive the pre-given usb_id argument. The exported snd_usbmidi_create() is unchanged by calling this new function internally. Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: dummy: Disable switching timer backend via sysfsTakashi Iwai2016-01-281-1/+1
| | | | | | | | | | | | | | | | | ALSA dummy driver can switch the timer backend between system timer and hrtimer via its hrtimer module option. This can be also switched dynamically via sysfs, but it may lead to a memory corruption when switching is done while a PCM stream is running; the stream instance for the newly switched timer method tries to access the memory that was allocated by another timer method although the sizes differ. As the simplest fix, this patch just disables the switch via sysfs by dropping the writable bit.

* ALSA: Add missing dependency on CONFIG_SND_TIMERTakashi Iwai2016-01-273-0/+8
| | | | | | | | | | | | Since the build of PCM timer may be disabled via Kconfig now, each driver that provides a timer interface needs to set CONFIG_SND_TIMER explicitly. Otherwise it may get a build error due to missing symbol.

* ALSA: compress: Disable GET_CODEC_CAPS ioctl for some architecturesTakashi Iwai2016-01-251-0/+11
| | | | | | | | | | | | | | | | | | | Some architectures like PowerPC can handle the maximum struct size in an ioctl only up to 13 bits, and struct snd_compr_codec_caps used by SNDRV_COMPRESS_GET_CODEC_CAPS ioctl overflows this limit. This problem was revealed recently by a powerpc change, as it's now treated as a fatal build error. This patch is a stop-gap for that: for architectures with less than 14 bit ioctl struct size, get rid of the handling of the relevant ioctl. We should provide an alternative equivalent ioctl code later, but for now just paper over it. Luckily, the compress API hasn't been used on such architectures, so the impact must be effectively zero.

This means that it can easily fill the log buffer. Since it's merely a normal error, it's safe to suppress it via pr_debug() instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the cache op codes defined in cacheops.h are split into a 2-bit cache identifier, and a 3-bit cache op code which does largely the same thing semantically regardless of the cache identifier. To allow the use of these definitions by KVM for decoding cache ops, break the definitions down into parts where it makes sense to do so, and add masks for the Cache and Op field within the cache op.
