We are planning to work on reducing memory footprint of ALSA, targeting on small memory embedded devices(e.g. IoT), this series focuses on disabling procfs, hw/sw params refinement, mmap, dpcm, dapm, compressed API, compat code APIs...
These first two patches is a start, add config menu in Kconfig, and disable ALSA proc FS once reducing memory footprint is selected, which can save about 9KB code size on x86_64 platform.
Comments are welcomed.
