[1]: http://openamp.github.io/docs/mca/coprocessor-memory-definition-v6.pdf --- Changes since V1: - Minor corrections on first 7 patches (error management) - Add "memory device" support on the top of first 7 patches. Goal is to answer use case reported during OpenAMP weekly discussion: - "Be able to specify memory region for vring and buffer allocation, even if no specific request defined in firmware resource table." Patches offer the capability to create a "memory device" associated to a carveout with a dedicated DMA memory pool. Different resource handlers are modified to look-up for specific carveout by name. If match found and associated "memory device" present, device is used instead of rproc platform device for allocation.
