Hello,
I am using i7-7980XE (skylake-x) CPU in Linux. after enabling IOMMU in Linux command line, I can see that DMAR is enabled in dmesg.
under /sys/devices/uncore_iio_x(x = 0 to 5), there are some runtime_status info. but while I run PCIe transfer over the bus, the runtime_status always shows disabled.
How can I check the uncore_iio are indeed enabled and running?
Thanks.
