Hi kernel experts, If some memory was reserved for a dma-able device using device tree's 'reserved-memory' property, if I do dma_alloc_coherent for the device, does it allocate memory in that reserved memory? I don't think so because dma_alloc_coherent works regardless of wether there is reserved memory for the device or not. Then how can I make the kernel reserve the dma memory from that reserved memory?
Thank you. Chan Kim
