Subject: [PATCH RESEND v3 0/2] reducing memory footprint of ALSA
Date: Wed, 27 May 2015 19:45:43 +0800 [thread overview]
Message-ID: <1432727145-6504-1-git-send-email-yang.jie@intel.com> (raw)
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...
We plan to enable those reducing items only for EXPERT, and
add knobs in sound/core/Kconfig.
These first two patches is a start, adding SND_PROC_FS to config
disable/enable ALSA proc FS, this disabling can save about 9KB
code size on x86_64 platform.
Changes in v3:
1. drop SND_REDUCED_MEMORY_FOOTPRINT and make configuration
available only for EXPERT;
2. move the configure into sound/core/Kconfig;
3. Add missing Signed-off-by for PATCH 2/2.
Changes in v2:
1. Prompt "Sound Proc FS Support" appears only when
SND_REDUCED_MEMORY_FOOTPRINT is true.
