[PATCH v2 0/8] misc: fastrpc: Add missing DSP FastRPC features
From: Srinivas Kandagatla
Date: Thu Dec 09 2021 - 07:07:00 EST
This patchset adds below DSP FastRPC features that have been missing in
upstream fastrpc driver and also cleans up channel context structure with kref.
- Add ablity to reflect if the DSP domain is secure/unsecure by creating
seperate device nodes for secured domain, this would used by SE policy
to restrict applications loading process on the DSP.
- Add new IOCTL to get DSP capabilites
- Add IOCTL to support mapping memory on the DSP.
Tested this series on DragonBoard 845c with TensorFlow.
