* ALSA: doc: ReSTize writing-an-alsa-driver documentTakashi Iwai2016-11-101-6206/+0
| | | | | | | | Another simple conversion from DocBook to ReST. This required a few manual fixups and reformats, but the most of contents are kept as is. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: Remove transfer_ack_{begin,end} callbacks from struct snd_pcm_runtimeLars-Peter Clausen2015-10-221-17/+2
| | | | | | | | | | | | | | While there is nothing wrong with the transfer_ack_begin and transfer_ack_end callbacks per-se, the last documented user was part of the alsa-driver 0.5.12a package, which was released 14 years ago and even predates the upstream integration of the ALSA core and has subsequently been superseded by newer alsa-driver releases. This seems to indicate that there is no need for having these callbacks and they are just cruft that can be removed.

| | | | | | | | Instead of the open code for the info call back of enum elements, recommend the use of snd_ctl_elem_info(), which will reduce lots of codes. Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: Mandate to pass a device pointer at card creation timeTakashi Iwai2014-02-121-45/+27
| | | | | | | | | | | | | | | | | | | | This is a part of preliminary works for modernizing the ALSA device structure. So far, we set card->dev at later point after the object creation. Because of this, the core layer doesn't always know which device is being handled before it's actually registered, and it makes impossible to show the device in error messages, for example. The first goal is to achieve a proper struct device initialization at the very beginning of probing. As a first step, this patch introduces snd_card_new() function (yes there was the same named function in the very past), in order to receive the parent device pointer from the very beginning. snd_card_create() is marked as deprecated. At this point, there is no functional change other than that. The actual change of the device creation scheme will follow later. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: Make snd_BUG_ON() always evaluate and return the conditional expressionChristine Spang2013-03-111-7/+5
| | | | | | | | | | Having snd_BUG_ON() only evaluate its conditional when CONFIG_SND_DEBUG is set leads to frequent bugs, since other similar macros in the kernel have different behavior. Let's make snd_BUG_ON() act like those macros so it will stop being accidentally misused. Signed-off-by: Christine Spang <christine.spang@oracle.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: Fix wrong description about hw constraintsTakashi Iwai2013-02-051-19/+20
| | | | | | | | | | The definitions of hw constraint functions are wrongly placed, and the description about the function is also wrong. hw_rule_channels_by_format actually refines the channels depending on the format, not vice versa.

* ALSA: module_param: make bool parameters really boolRusty Russell2011-12-191-1/+1
| | | | | | | | | | | | module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version.

* ALSA: mpu401: clean up interrupt specificationClemens Ladisch2011-09-141-15/+21
| | | | | | | | | | | | | | | | | | | | | | | The semantics of snd_mpu401_uart_new()'s interrupt parameters are somewhat counterintuitive: To prevent the function from allocating its own interrupt, either the irq number must be invalid, or the irq_flags parameter must be zero. At the same time, the irq parameter being invalid specifies that the mpu401 code has to work without an interrupt allocated by the caller. This implies that, if there is an interrupt and it is allocated by the caller, the irq parameter must be set to a valid-looking number which then isn't actually used. With the removal of IRQF_DISABLED, zero becomes a valid irq_flags value, which forces us to handle the parameters differently. This patch introduces a new flag MPU401_INFO_IRQ_HOOK for when the device interrupt is handled by the caller, and makes the allocation of the interrupt to depend only on the irq parameter. As suggested by Takashi, the irq_flags parameter was dropped because, when used, it had the constant value IRQF_DISABLED.

* ALSA: Move ALSA docbooks to be with the rest of the kernel docbooksRandy Dunlap2009-03-091-0/+6216
Move ALSA docbooks to be with the rest of the kernel docbooks and add them to the Makefile so that they build. Latter required a few minor changes to alsa .tmpl files. (I did not remove all of the trailing whitespace in the .tmpl files.)
