ALSA: Make SND_PCMTEST depend on DEBUG_FS

2023-08-18T07:10:22+00:00

Since pcmtest is a test module that manipulates or gets notification via debugfs, without DEBUG_FS it can not work fine. So make SND_PCMTEST depend on DEBUG_FS.

ALSA: Implement the new Virtual PCM Test Driver

2023-06-07T11:08:53+00:00

We have a lot of different virtual media drivers, which can be used for testing of the userspace applications and media subsystem middle layer. However, all of them are aimed at testing the video functionality and simulating the video devices. For audio devices we have only snd-dummy module, which is good in simulating the correct behavior of an ALSA device. I decided to write a tool, which would help to test the userspace ALSA programs (and the PCM middle layer as well) under unusual circumstances to figure out how they would behave. So I came up with this Virtual PCM Test Driver. This new Virtual PCM Test Driver has several features which can be useful during the userspace ALSA applications testing/fuzzing, or testing/fuzzing of the PCM middle layer. Not all of them can be implemented using the existing virtual drivers (like dummy or loopback). Here is what can this driver do: - Simulate both capture and playback processes - Generate random or pattern-based capture data - Inject delays into the playback and capturing processes - Inject errors during the PCM callbacks Also, this driver can check the playback stream for containing the predefined pattern, which is used in the corresponding selftest to check the PCM middle layer data transferring functionality. Additionally, this driver redefines the default RESET ioctl, and the selftest covers this PCM API functionality as well. The driver supports both interleaved and non-interleaved access modes, and have separate pattern buffers for each channel. The driver supports up to 4 channels and up to 8 substreams.

ALSA: add HAS_IOPORT dependencies

2023-05-22T14:43:47+00:00

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends not being declared. We thus need to add HAS_IOPORT as dependency for those drivers using them.

ALSA: Add generic serial MIDI driver using serial bus API

2022-05-12T09:54:13+00:00

Generic serial MIDI driver adding support for using serial devices compatible with the serial bus as raw MIDI devices, allowing using additional serial devices not compatible with the existing serial-u16550 driver. Supports only setting standard serial baudrates on the underlying serial device; however, the underlying serial device can be configured so that a requested 38.4 kBaud is actually the standard MIDI 31.25 kBaud. Supports DeviceTree configuration. Signed-off-by: Daniel Kaehn Reviewed-by: Rob Herring Link: https://lore.kernel.org/r/20220509145933.1161526-3-kaehndan@gmail.com Signed-off-by: Takashi Iwai
