Thu, 17 Aug 2023 09:37:39 +0000

ALSA: Make SND_PCMTEST depend on DEBUG_FSSince pcmtest is a test module that manipulates or getsnotification via debugfs, without DEBUG_FS it can not work fine.So make SND_PCMTEST depend on DEBUG_FS.Signed-off-by: Ruan Jinjie Acked-by: Ivan Orlov Link: https://lore.kernel.org/r/20230817093740.1732738-1-ruanjinjie@huawei.comSigned-off-by: Takashi Iwai List of files: /linux-6.15/sound/drivers/Kconfig

315a3d57 - ALSA: Implement the new Virtual PCM Test Driver

Tue, 06 Jun 2023 19:32:53 +0000

ALSA: Implement the new Virtual PCM Test DriverWe have a lot of different virtual media drivers, which can be used fortesting of the userspace applications and media subsystem middle layer.However, all of them are aimed at testing the video functionality andsimulating the video devices. For audio devices we have only snd-dummymodule, 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 ALSAprograms (and the PCM middle layer as well) under unusual circumstancesto figure out how they would behave. So I came up with this Virtual PCMTest Driver.This new Virtual PCM Test Driver has several features which can be usefulduring the userspace ALSA applications testing/fuzzing, or testing/fuzzingof the PCM middle layer. Not all of them can be implemented using theexisting virtual drivers (like dummy or loopback). Here is what can thisdriver 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 callbacksAlso, this driver can check the playback stream for containing thepredefined pattern, which is used in the corresponding selftest to checkthe PCM middle layer data transferring functionality. Additionally, thisdriver redefines the default RESET ioctl, and the selftest covers this PCMAPI functionality as well.The driver supports both interleaved and non-interleaved access modes, andhave separate pattern buffers for each channel. The driver supports up to4 channels and up to 8 substreams.Signed-off-by: Ivan Orlov Acked-by: Jaroslav Kysela Link: https://lore.kernel.org/r/20230606193254.20791-2-ivan.orlov0322@gmail.comSigned-off-by: Takashi Iwai List of files: /linux-6.15/sound/drivers/Kconfig

Supports only setting standard serial baudrates onthe underlying serial device; however, the underlying serial device canbe configured so that a requested 38.4 kBaud is actually the standard MIDI31.25 kBaud.

111b0cdb - ALSA: seq: Allow the modular sequencer registration

Fri, 09 Jun 2017 13:11:58 +0000

ALSA: seq: Allow the modular sequencer registrationMany drivers bind the sequencer stuff in off-load by another drivermodule, so that it's loaded only on demand. In the current code, thismechanism doesn't work when the driver is built-in while the sequenceris module. We check with IS_REACHABLE() and enable only when thesequencer is in the same level of build.However, this is basically a overshoot. The binder code(snd-seq-device) is an individual module from the sequencer core(snd-seq), and we just have to make the former a built-in whilekeeping the latter a module for allowing the scenario like the above.This patch achieves that by rewriting Kconfig slightly. Now, a driverthat provides the manual sequencer device binding should selectCONFIG_SND_SEQ_DEVICE in a way as select SND_SEQ_DEVICE if SND_SEQUENCER != nNote that the "!=n" is needed here to avoid the influence of thesequencer core is module while the driver is built-in.Also, since rawmidi.o may be linked with snd_seq_device.o whenbuilt-in, we have to shuffle the code to make the linker happy.(the kernel linker isn't smart enough yet to handle such a case.)That is, snd_seq_device.c is moved to sound/core from sound/core/seq,as well as Makefile.Last but not least, the patch replaces the code using IS_REACHABLE()with IS_ENABLED(), since now the condition meets always when enabled.Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/drivers/Kconfig

0181307a - ALSA: seq: Reorganize kconfig and build

Fri, 09 Jun 2017 12:40:18 +0000

ALSA: seq: Reorganize kconfig and buildThis is a slightly intensive rewrite of Kconfig and Makefile aboutALSA sequencer stuff.The first major change is that the kconfig items for the sequencer aremoved to sound/core/seq/Kconfig. OK, that's easy.The substantial change is that, instead of hackish top-level moduleselection in Makefile, we define a Kconfig item for each sequencermodule. The driver that requires such sequencer components selectexclusively the kconfig items. This is more straightforward andstandard way.Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/drivers/Kconfig
