Subject: [PATCH v2 0/8] misc: fastrpc: Add missing DSP FastRPC features
Date: Thu,  9 Dec 2021 12:06:18 +0000	[thread overview]
Message-ID: <20211209120626.26373-1-srinivas.kandagatla@linaro.org> (raw)

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.
