* ALSA: Use fallthrough pseudo-keywordGustavo A. R. Silva2020-07-091-1/+1

| | | | | | | | | | 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.

The only remaining pci_set_drvdata(NULL) is in azx_firmware_cb() in hda_intel.c.

* ALSA: mpu401: clean up interrupt specificationClemens Ladisch2011-09-141-2/+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.

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).
