|
|
+ Multipd Peripheral Image Loader loads firmware and boots Q6 protection domain,
|
|
+ WCSS protection domain remoteproc's on the Qualcomm IPQ9574, IPQ5332 SoC.
|
|
+ Protection domain is similar to process in Linux. Here QDSP6 processor runs
|
|
+ each wifi radio functionality on a separate process. One process can't access
|
|
+ other process resources, so this is termed as PD i.e protection domain.

|
|
+ WCSS means 'wireless connectivity sub system', in simple words it's a
|
|
+ wifi radio block. In multipd model, Q6 root protection domain will
|
|
+ provide services to WCSS user protection domain. In other words WCSS
|
|
+ protection domains depends on Q6 protection domain i.e Q6 should be up
|
|
+ before WCSS, similarly Q6 should shut down after all WCSS domains are
|
|
+ down. It can be achieved by building parent-child topology between Q6
|
|
+ and WCSS domain's i.e keeping wcss node as sub node of Q6 device node.
