[alsa-devel] [PATCH 0/2] reducing memory footprint of ALSA

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.

Changes in v2:
Prompt "Sound Proc FS Support" appears only when
SND_REDUCED_MEMORY_FOOTPRINT is true.

Jie Yang (2):
  ALSA: Kconfig: add config menu for reduced memory footprint
  ALSA: set no sound proc fs for reduced memory footprint
