[PATCH v5 1/2] misc: fastrpc: support complete DMA pool access to the DSP

2024-05-24 Thread Dylan Van Assche
To support FastRPC Context Banks which aren't mapped via the SMMU, make the whole reserved memory region available to the DSP to allow access to coherent buffers. This is performed by assigning the memory to the DSP via a hypervisor call to set the correct permissions for the Virtual Machines on
