You should be able to achieve this without any remoteproc core changes. You can do this by defining a reserved-memory node in your DTS file (can be a CMA pool or a DMA pool), assigning the node using memory-region in your remoteproc DT node and using the function, of_reserved_mem_device_init() in your remoteproc driver. regards Suman > > Wendy Liang (3): > remoteproc: add rproc mem resource entry > remoteproc: add rproc_mem resource entry handler > remoteproc: Release DMA declare mem when cleanup rsc > > drivers/remoteproc/remoteproc_core.c | 40 > ++++++++++++++++++++++++++++++++++++ > include/linux/remoteproc.h | 23 ++++++++++++++++++++- > 2 files changed, 62 insertions(+), 1 deletion(-) >
