若是64位地址,则需要使用Prefetchable Base Upper 32 Bits和Prefetchable Limit Upper 32 Bits。 Prefetchable Memory Base表示预取地址空间基地址,按1MB对齐,即低20位为0。 Prefetchable Memory Limit表示预取地址空间最大地址,低20位都为1,即为0xFFFFF。 图中预取地址空间为64位,因此I/O地址空间范围为0x240000000-...
在一般情况下,Slot user number不会直接转换为PCIE slot number。这是因为Slot user number是在ACPI表中定义的用户自定义编号,而PCIE slot number是主板或系统制造商在物理槽位上标识的编号。 Slot user number主要在操作系统层面用于识别和区分PCI插槽,而PCIE slot number主要用于物理槽位的标识和组织。它们在不同的...

由于DM8168不支持PCIE设备的热插拔,而设置SW5为OFF的目的在于,保证EP设备优先于RC设备启动,使用EP设备的复位信号通过SLOT的A11来复位RC设备。 当你的网卡插PCIE slot的时候,你看一下,是否是A11脚的电平不正常,这样导致了DM8168一直处于复位状态,无法正常启动。
确定接口方式(MM or ST)，根据接口方式调用脚本dma_memory_mapped_test.sh或者dma_streaming_test。dma_memory_mapped_test.sh和dma_streaming_test脚本首先使用dma_to_device命令发送测试数据到BRAM，然后使用dma_from_device命令从BRAM中取出数据，最后对比两个文件的数据是否一致。测试记过如下图所示。
To check the power capacity of your host's PCIe slots, execute the command lspci -vvv | grep PowerLimit. For instance: # lspci -vvv | grep PowerLimit Slot #6, PowerLimit 75.000W; Interlock- NoCompl- Slot #1, PowerLimit 75.000W; Interlock- NoCompl- Slot #4, PowerLimit 75.000W; ...
