vendor_init is a subcontext of init which is responsible for handling the vendor-defined services and vendor-defined actions. This is mainly to enforce the Treble architecture in which the vendor components are provided with a less-privileged context than the system components because they are less-trusted. However, in case of microdroid, both the system and the vendor partitions are from the same entity. As VMs don't have direct access to any of the underlying hardware, the vendor partition is targeting the virtual platform, not the real hw platform. There really is no need for the discrimination. This CL disables the creation of the vendor_init subcontext when init runs in microdroid. Bug: 201363575 Test: atest MicrodroidHostTestCases Change-Id: Ie5e47d84e9e245565239b4f2159e8182b457699d
