From: Peter Ujfalusi Date: Thu, 20 Oct 2022 12:12:30 +0000 (+0300) Subject: ASoC: SOF: Add path definition for external firmware libraries X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=25bbc0c59ee15cfc37acaaa831de447f2c2fbcb9;p=linux.git ASoC: SOF: Add path definition for external firmware libraries IPC4 based firmware supports dynamically loaded external libraries. The libraries will be not stored alongside of the firmware or tplg files. For intel platforms the default path will be: intel/avs-lib|sof-ipc4-lib// if a community key is used on the given machine then the libraries will be under 'community' directory, like it is done for the firmware itself.
