| * treewide, serdev: change receive_buf() return type to size_tFrancesco Dolcini2024-01-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | receive_buf() is called from ttyport_receive_buf() that expects values ">= 0" from serdev_controller_receive_buf(), change its return type from ssize_t to size_t. The need for this clean-up was noticed while fixing a warning, see commit 94d053942544 ("Bluetooth: btnxpuart: fix recv_buf() return value"). Changing the callback prototype to return an unsigned seems the best way to document the API and ensure that is properly used. GNSS drivers implementation of serdev receive_buf() callback return directly the return value of gnss_insert_raw(). gnss_insert_raw() returns a signed int, however this is not an issue since the value returned is always positive, because of the kfifo_in() implementation. gnss_insert_raw() could be changed to return also an unsigned, however this is not implemented here as request by the GNSS maintainer Johan Hovold.

| * ALSA: aloop: Introduce a function to get if access is interleaved modeChancel Liu2024-01-121-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a use case that playback stream of a loopback cable works on RW_INTERLEAVED mode while capture stream works on MMAP_INTERLEAVED mode: aplay -Dhw:Loopback,0,0 S32_48K_2ch.wav; arecord -Dplughw:Loopback,1,0 -fS32_LE -r16000 -c2 cap.wav; The plug plugin handles only slave PCM support MMAP mode. Not only plug plugin but also other plugins like direct plugins(dmix/dsnoop/dshare) work on MMAP access mode. In this case capture stream is the slave PCM works on MMAP_INTERLEAVED mode. However loopback_check_format() rejects this access setting and return: arecord: pcm_read:2240: read error: Input/output error To fix it a function called is_access_interleaved() is introduced to get if access is interleaved mode. If both access of capture stream and playback stream is interleaved mode loopback_check_format() will allow this kind of access setting.

* ALSA: aloop: Add support for the non-interleaved access modeIvan Orlov2023-10-061-3/+28
| | | | | | | | | | | | | | | | | | | | | | | The current version of the loopback driver supports interleaved access mode only. This patch introduces support for the non-interleaved access mode. When in the interleaved mode, the 'copy_play_buf' function copies data from the playback to the capture buffer using one memcpy call. This call copies samples for multiple, interleaved channels. In the non-interleaved mode we have multiple channel buffers, so we have to perform multiple memcpy calls to copy samples channel after channel. Add new function called 'copy_play_buf_part_n', which copies a part of each channel buffer from playback to capture. Modify the 'copy_play_buf' to use the corresponding memory copy function(just memcpy / copy_play_buf_part_n) depending on the access mode.

* ALSA: Implement the new Virtual PCM Test DriverIvan Orlov2023-06-073-0/+745
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: mts64: Convert to platform remove callback returning voidUwe Kleine-König2023-03-201-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

* ALSA: pcsp: Make hrtimer forwarding more robustThomas Gleixner2021-09-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | The hrtimer callback pcsp_do_timer() prepares rearming of the timer with hrtimer_forward(). hrtimer_forward() is intended to provide a mechanism to forward the expiry time of the hrtimer by a multiple of the period argument so that the expiry time greater than the time provided in the 'now' argument. pcsp_do_timer() invokes hrtimer_forward() with the current timer expiry time as 'now' argument. That's providing a periodic timer expiry, but is not really robust when the timer callback is delayed so that the resulting new expiry time is already in the past which causes the callback to be invoked immediately again. If the timer is delayed then the back to back invocation is not really making it better than skipping the missed periods. Sound is distorted in any case. Use hrtimer_forward_now() which ensures that the next expiry is in the future. This prevents hogging the CPU in the timer expiry code and allows later on to remove hrtimer_forward() from the public interfaces.
