* [dma] Move I/O buffer DMA operations to iobuf.hMichael Brown2020-11-281-10/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Include a potential DMA mapping within the definition of an I/O buffer, and move all I/O buffer DMA mapping functions from dma.h to iobuf.h. This avoids the need for drivers to maintain a separate list of DMA mappings for each I/O buffer that they may handle. Network device drivers typically do not keep track of transmit I/O buffers, since the network device core already maintains a transmit queue. Drivers will typically call netdev_tx_complete_next() to complete a transmission without first obtaining the relevant I/O buffer pointer (and will rely on the network device core automatically cancelling any pending transmissions when the device is closed). To allow this driver design approach to be retained, update the netdev_tx_complete() family of functions to automatically perform the DMA unmapping operation if required. For symmetry, also update the netdev_rx() family of functions to behave the same way. As a further convenience for drivers, allow the network device core to automatically perform DMA mapping on the transmit datapath before calling the driver's transmit() method. This avoids the need to introduce a mapping error handling code path into the typically error-free transmit methods. With these changes, the modifications required to update a typical network device driver to use the new DMA API are fairly minimal: - Allocate and free descriptor rings and similar coherent structures using dma_alloc()/dma_free() rather than malloc_phys()/free_phys() - Allocate and free receive buffers using alloc_rx_iob()/free_rx_iob() rather than alloc_iob()/free_iob() - Calculate DMA addresses using dma() or iob_dma() rather than virt_to_bus() - Set a 64-bit DMA mask if needed using dma_set_mask_64bit() and thereafter eliminate checks on DMA address ranges - Either record the DMA device in netdev->dma, or call iob_map_tx() as part of the transmit() method - Ensure that debug messages use virt_to_phys() when displaying "hardware" addresses Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [intel] Allow for the use of advanced TX descriptorsMichael Brown2015-05-161-2/+4
| | | | | | | | | | | | | | | | Intel virtual function NICs almost work with the use of "legacy" transmit and receive descriptors (which are backwards compatible right back to the original Intel Gigabit NICs). Unfortunately the "TX switching" feature (which allows for VM<->VM traffic to be looped back within the NIC itself) does not work when a legacy TX descriptor is used: the packet is instead sent onto the wire. Fix by allowing for the use of an "advanced" TX descriptor (containing exactly the same information as is found in the "legacy" descriptor). Signed-off-by: Michael Brown <mcb30@ipxe.org>
