virtual void allocate_buffer(size_t size, const std::string &name, bool vmem, bool free_previous_cmem = true) override

Parameters:

size -- of the FromHost DMA buffer.
name -- of the buffer passed to the CMEM driver.
vmem -- allocate the buffer without using the CMEM driver.
free_previous_cmem -- claim an unlocked/orphaned CMEM buffer with the same name.
