Re: [alsa-devel] [PATCH 1/2] ALSA: Kconfig: add config menu for reduced memory footprint

For some embedded devices, we need reduce code size and data footprint as much as possible, e.g. disabling procfs, hw/sw params refinement, mmap, dpcm, dapm, compressed API...

Here add root config menu for those configuration, and disable procfs once reduced memory footprint is selected.

I'd like to move this into sound/core. Also, the kconfig name appears a bit too lengthy to me.

+config SND_PROC_FS

• bool "Sound Proc FS Support"

This should be bool "Sound Proc FS Support" if !SND_REDUCED_MEMORY_FOOTPRINT depends on PROC_FS

In this way, this prompt would appear only when SND_REDUCED_MEMORY_FOOTPRINT is set, i.e. only for experts.

thanks,
