PCIe Cache Snoop for Data Transfer from PCIe Device to Jetson TX2

Hi.

Would you tell me if Jetson TX2 has a cache snoop funciton when a PCIe device transfers data to the Jetson TX2?
Or, we don’t need such function? If the reclaimable PCIe region (0x4000:0000) is non-cacheable, snoop may not be needed.

Thanks.

PCIe region is a non-cacheable region hence snoop is not needed.

vidyas,

Thank you for the answer.

I forgot about the PCIE0 aperture region. Is PCIE0 also non-cacheeable?
I assume that all MMIO (Memory Mapped IO) regions are non-cacheable.

Thanks.

Yes.

Thank you.
