kv2019i · kv2019i · commit 00b9607610e7 · 2025-07-04T11:42:59.000+03:00
Add an OS overlay for Linux. This overlay configures SOF to
be used with SOF Linux kernel driver. The overlay modifies
Kconfig configuration options to align with requirements of
of the Linux driver.

Similar overlays may be added later for other OS'es.
