[alsa-devel] [RFC PATCH] ASoC: Intel: use common helpers to detect CPUs
Pierre-Louis Bossart
pierre-louis.bossart at linux.intel.com
Tue May 28 22:02:55 CEST 2019
We have duplicated code in multiple locations (atom, machine drivers,
SOF) to detect Baytrail, Cherrytrail and other SOCs. This is not very
elegant, and introduces dependencies on CONFIG_X86 that prevent
COMPILE_TEST from working.
Add common helpers to provide same functionality in a cleaner
way. This will also help support the DMI-based quirks being introduced
to handle SOF/SST autodetection.
FIXME:
0. does this fix COMPILE_TEST issues reported by Randy?
1. should the include file moved to include/sound? this would be handy
for the SOF/SST mutual exclusion?
2. is there a better way to do this for all Intel chips or do we keep
this in sound/? Andy?
