* sound: Implement AFMT_FLOAT supportChristos Margiolis2025-03-301-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even though the OSS manual [1] advises against using AFMT_FLOAT, there are applications that expect the sound driver to support it, and might not work properly without it. This patch adds AFMT_F32_LE|BE (as well as AFMT_FLOAT for OSS compatibility) in sys/soundcard.h and implements AFMT_F32_LE|BE <-> AFMT_S32_LE|BE conversion functions. As a result, applications can write/read floats to/from sound(4), but internally, because sound(4) works with integers, we convert floating point samples to integer ones, before doing any processing. The reason for encoding/decoding IEEE754s manually, instead of using fpu_kern(9), is that fpu_kern(9) is not supported by all architectures, and also introduces significant overhead. The IEEE754 encoding/decoding implementation has been written by Ariff Abdullah [2].

* sound: Refactor the format conversion frameworkChristos Margiolis2025-03-101-272/+6
| | | | | | | | | | | | | | | | | Merge the PCM_READ|WRITE_* macros defined in pcm/pcm.h, as well as the intpcm_read|write_* macros defined in pcm/feeder_format.c, into six inline functions: pcm_sample_read|write[_norm|calc](). The absence of macro magic makes the code significantly easier to read, use and modify. Since these functions take the input/output format as a parameter, get rid of the read() and write() function pointers defined in struct feed_format_info, as well as the feeder_format_read|write_op() functions, and use the new read/write functions directly.

* sound tests: Fix downshift calculation in pcm_read_write testFlorian Walpen2025-02-181-4/+11
| | | | | | | | | | | | | | | In some situations the feeders in the sound module lower the pcm sample resolution through a downshift of the sample value. The pcm_read_write test implements this operation with an arithmetic division to avoid implementation defined or architecture specific behavior. Due to different rounding, the test produced marginally different sample values, which made the test fail on 32 bit architectures. Correct this.

* sound tests: Fix 32bit calculation detection in pcm_read_writeFlorian Walpen2025-01-231-3/+9
| | | | | | | | | | | | | Fix a mistake in the pcm_read_write test that would result in not properly detecting 32bit calculation on 32bit architectures like i386. As a consequence, the wrong values would be checked, thus failing the test.

* sound: Unit test the pcm sample read and write macrosFlorian Walpen2025-01-212-0/+513
| | | | | | | | | | | | | | | | Main goal is to have a unit test, with sample test data that is verified against the current macro implementation of pcm sample read and write functions. With a test in place, we can proceed on a planned refactoring of the sample read and write code, and confidently check the new code for regressions. Implementation of the unit test itself has to avoid any cast or conversion affected by endianness, to make the tests compatible with all machine architectures.
