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.
