* Memory Share Driver (MEMSHARE)
|
||
|
|
|
||
|
|
The Memshare driver implements a Kernel QMI service on the
|
||
|
|
LA-APSS, which is responsible for providing contiguous physical
|
||
|
|
memory to MPSS for use cases when the modem requires additional
|
||
|
|
memory (e.g. GPS).
|
||
|
|
|
||
|
|
Required properties for Memshare

||
|
|
|
||
|
|
- compatible: Must be "qcom,memshare"
|
||
|
|
|
||
|
|
Required properties for child nodes:
|
||
|
|
|
||
|
|
- compatible: Must be "qcom,memshare-peripheral"
|
||
|
|
|
||
|
|
- qcom,peripheral-size: Indicates the size (in bytes) required for that child.
|
||
|
|
|
||
|
|
- qcom,client-id: Indicates the client id of the child node.
|
||
|
|
|
||

the following:
|
||
