一 启动Scatter‐Gather DMA之前的PCI 32位内存空间。链中的每个描述符都有以下格式:一个字:数据的32位PCI地址下限(每页必须在8字节边界上对齐),二个字:32位PCI数据地址上限(32位寻址$0),三个字:要传输到PCI地址的字节数(每页大小必须是8字节的倍数),四个字:下一个描述符的PCI地址(在该字段中写入$1以表示链的结束)此外,保留链所指向的所有数据块的总大小。此总长度值必须写入DMA传输大小寄存器。1.基址寄存器0存储本地控制和配置寄存器(包括DMA控制寄存器)的起始地址。此寄存器中的值为PCIBAR0.2。必须配置六个DMA寄存器才能设置DMA周期。这些寄存器在DMA循环后将保持不变。61 PMC-5565PIORC反射式存储板3.要启动和监控传输,请按如下方式访问DMACR0:DMA通道0命令/状态寄存器:DMACR0位于PCIBAR0+偏移量$A8。写入$0003开始传输,然后轮询同一寄存器。当比特4为高(1)时,DMA循环完成。注:轮询读取周期优先于DMA周期PCI 32‐bit memory space before starting a Scatter‐Gather DMA. Each descriptor in the chain has this format: 1st Dword: Lower 32‐bit PCI Address for Data (each page must be aligned on an 8‐byte boundary), 2nd Dword: Upper 32‐bit PCI Address for Data ($0 for 32‐bit addressing), 3rd Dword: Number of bytes to transfer to/from PCI Address (each page size must be a multiple of 8 bytes), 4th Dword: PCI Address of Next Descriptor (write $1 in this field to denote end of chain) Also, keep a total for the size of all data blocks pointed to by the chain. This total length value must be written to the DMA transfer size register. 1. Base Address Register 0 stores the starting address of the Local Control and Configuration registers, which include the DMA Control registers. The value in this register is PCIBAR0. 2. There are six DMA registers that must be configured to set up the DMA cycle. These registers will remain unchanged after the DMA cycle. 61 PMC-5565PIORC Reflective Memory Board 3. To initiate and monitor the transfer, access DMACSR0 as follows: DMA channel 0 Command/Status register: DMACSR0 at PCIBAR0 + offset $A8. Write $0003 to start the transfer, then poll the same register. When Bit 4 is high (1), the DMA cycle is complete. NOTE Polling read cycles take priority over the DMA cycles
