PURPOSE: To improve data transferring efficiency between a DMA device with a chain function and a DMA device without a chain function by adding a simple chain function to the DMA without the chain function at the time of operating DMA data transfer between those DMA devices.永井 正幸...
Special note about PCI: PCI-X specification requires PCI-X devices to support 64-bit addressing (DAC) for all transactions. And at least one platform (SGI SN2) requires 64-bit consistent allocations to operate correctly when the IO bus is in PCI-X mode. 关于 PCI 的特别说明:PCI-X 规范要...

Under first-party DMA, the device uses a channel from the system's DMA engine to drive that device's DMA bus cycles. Use the ddi_dmae_1stparty(9F) function to configure this channel in a cascade mode so that the DMA engine does not interfere with the transfer....
