2020-01-05ALSA: azt3328: More constificationTakashi Iwai1-1/+1
Apply const prefix to the static initial register table. Just for minor optimization and no functional changes. Link: https://lore.kernel.org/r/20200105144823.29547-61-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2020-01-03ALSA: pci: Constify snd_kcontrol_new itemsTakashi Iwai1-1/+1
Most of snd_kcontrol_new definitions are read-only and passed as-is. Let's declare them as const for further optimization. There should be no functional changes by this patch. Link: https://lore.kernel.org/r/20200103081714.9560-38-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2020-01-03ALSA: pci: Constify snd_ac97_bus_ops definitionsTakashi Iwai1-1/+1
Now snd_ac97_bus() takes the const ops pointer, so we can define the snd_ac97_bus_ops locally as const as well for further optimization. There should be no functional changes by this patch.

2016-09-02ALSA: constify snd_pcm_ops structuresJulia Lawall1-3/+3
Check for snd_pcm_ops structures that are only stored in the ops field of a snd_soc_platform_driver structure or passed as the third argument to snd_pcm_set_ops.

Calling synchronize_irq() right before free_irq() is quite useless. On one hand the IRQ can easily fire again before free_irq() is entered, on the other hand free_irq() itself calls synchronize_irq() internally (in a race condition free way) before any state associated with the IRQ is freed.

This is a similar cleanup like the commit [3db084fd0af5: ALSA: fm801: PCI core handles power state for us]. Since pci_set_power_state(), pci_save_state() and pci_restore_state() are already done in the PCI core side, so we don't need to it doubly.

2013-05-29ALSA: PCI: Remove superfluous pci_set_drvdata(pci, NULL) at removeTakashi Iwai1-1/+0
As drvdata is cleared to NULL at probe failure or at removal by the driver core, we don't have to call pci_set_drvdata(pci, NULL) any longer in each driver. The only remaining pci_set_drvdata(NULL) is in azx_firmware_cb() in hda_intel.c. Since this function itself releases the card instance, we need to clear drvdata here as well, so that it won't be released doubly in the remove callback. Signed-off-by: Takashi Iwai <tiwai@suse.de>

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.

2011-09-14ALSA: mpu401: clean up interrupt specificationClemens Ladisch1-2/+3
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.

2011-06-10ALSA: use KBUILD_MODNAME for request_irq argument in sound/pci/*Takashi Iwai1-1/+1
The name argument of request_irq() appears in /proc/interrupts, and it's quite ugly when the name entry contains a space or special letters. In general, it's simpler and more readable when the module name appears there, so let's replace all entries with KBUILD_MODNAME. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-06-10ALSA: Use KBUILD_MODNAME for pci_driver.name entriesTakashi Iwai1-1/+1
The convention for pci_driver.name entry in kernel drivers seem to be the module name or equivalent ones. But, so far, almost all PCI sound drivers use more verbose name like "ABC Xyz (12)", and these are fairly confusing when appearing as a file name. This patch converts the all pci_driver.name entries in sound/pci/* to use KBUILD_MODNAME for more unified appearance. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-02-19ALSA: azt3328: add custom AC97 semi-emulation use standard ALSA AC97 layerAndreas Mohr1-48/+402
Make use of the very flexible ALSA ac97 layer (hooks for custom I/O!) on this weird AC97 copycat hardware, via semi-extended I/O translation/emulation. Some 5kB binary/loaded size saved (well... additional huge AC97 module penalty not factored in, of course ;-P). Given that the driver previously had 20kB that's not bad, but the much more important thing is to have AC97 layer stress-tested with a thoroughly weird AC97 copycat (or, simply put, if it were not for this AC97 test aspect, this effort would merely have been a nut job ;).

. Fix PulseAudio "ALSA driver bug" issue (if we have two alternated areas within a 64k DMA buffer, then max period size should obviously be 32k only). Back references: http://pulseaudio.org/wiki/AlsaIssues http://fedoraproject.org/wiki/Features/GlitchFreeAudio . In stop timer function, need to supply ACK in the timer control byte. . Minor log output correction When I did my first PA testing recently, the period size bug resulted in quite precisely observeable half-period-based playback distortion. PA-based operation is quite a bit more underrun-prone (despite its zero-copy optimizations etc.) than raw ALSA with this rather spartan sound hardware implementation on my puny Athlon. Note that even with this patch, azt3328 still doesn't work for both cases yet, PA tsched=0 and tsched (on tsched=0 it will playback tiny fragments of periods, leading to tiny stuttering sounds with some pauses in between, whereas with timer-scheduled operation playback works fine - minus some quite increased underrun trouble on PA vs. ALSA, that is).

Practical result of this bug was that when shutting down _either_ playback or capture, _both_ streams dropped dead :P Tested, working (plus resume) and checkpatch.pl:ed on 2.6.30-rc5, applies cleanly to 2.6.30 proper with my previous (committed) patches applied.
