+ * Copyright 2023 Ivan Orlov <ivan.orlov0322@gmail.com>
+ *
+ * This is a simple virtual ALSA driver, which can be used for audio applications/PCM middle layer
+ * testing or fuzzing.
+ * It can:
+ *	- Simulate 'playback' and 'capture' actions
+ *	- Generate random or pattern-based capture data
+ *	- Check playback buffer for containing looped template, and notify about the results
+ *	through the debugfs entry
+ *	- Inject delays into the playback and capturing processes. See 'inject_delay' parameter.
+ *	- Inject errors during the PCM callbacks.
+ *	- Register custom RESET ioctl and notify when it is called through the debugfs entry
+ *	- Work in interleaved and non-interleaved modes
+ *	- Support up to 8 substreams
+ *	- Support up to 4 channels
+ *	- Support framerates from 8 kHz to 48 kHz
+ *
+ * When driver works in the capture mode with multiple channels, it duplicates the looped
+ * pattern to each separate channel. For example, if we have 2 channels, format = U8, interleaved
+ * access mode and pattern 'abacaba', the DMA buffer will look like aabbccaabbaaaa..., so buffer for
+ * each channel will contain abacabaabacaba... Same for the non-interleaved mode.
+ *
+ * However, it may break the capturing on the higher framerates with small period size, so it is
+ * better to choose larger period sizes.
+ *
+ * You can find the corresponding selftest in the 'alsa' selftests folder.
