SpletLater i find that the lost one is because the memory LOW address from FFC to 000 ， then i think the 4K boundary is the memory low address ,can you tell me that the idea is right or … SpletI am not too keen in the low level details of PCIe, but you seem to be wondering how the PCIe bus itself communicates with the CPU. It does so like anything else that communicates with the CPU: Memory mapping - i.e. a device is "mapped" where reads and writes to a range of addresses don't go to RAM, but a device or controller.

Splet22. nov. 2024 · Through this, it is possible to directly address all the PCIe device memory by the host user/kernel thread like normal host DRAM space. I was able to test this concept by mapping the physical contiguous memory region for the PCIe device memory onto user space virtual memory address space, using RX560 on Linux through mmap().
