Adapting map/unmap() changes to pci-epf-ntb/vntb Removing alignment codes on RC side completelyĢ. This is a RFC, and it has patches for testing only. I tested this changes on RENESAS board has DWC PCIeC. Adapt the pci-epf-test to the map/unmap function updated at first patch. Implement the support function for DWC EPC driver.ģ. With adding epc driver support as EPC ops.Ģ. Improve a pci epc unmap/map functions to cover the alignment restriction This patchset addresses with the alignment restriction on EP size. So, a EP side should deal with the alignment restriction. VirtIO, NVMe andĮtc) cannot expect that a driver for the device prepares an aligned memory. However, a EP module which emulate a device (e.g. On epf test, RC module prepares an aligned memory, and EP module maps the The mapping is needed to access memory of other side.
