Hi all, If there are multiple PCIe cards of the same type, e.g. 3 or 4 network controllers, in a node. Now, if one allocates a buffer using pci_alloc_consistent() using pci_dev struct of one of the card. 1) Whether that buffer can be used by remaining cards also ? OR Whether DMA addresses returned by pci_alloc_consistent() can be used by all the cards explained in above situation ? 2) What will be the case for multiple platforms/architectures ? 3) There can be multiple PCIe bridges giving multiple slots on some machines. What will happen, when above situation is considered in such machines ? Any link of reference can be helpful.
