It was incredibly helpful. I ran it across all the CDAT files found in my sysfs. For context, my system currently has 16 CXL endpoints attached (from `endpoint9` to `endpoint24`): /sys/devices/platform/ACPI0017:00/root0/port.../endpoint.../CDAT As Dave Jiang recently pointed out in this thread, the Intel BIOS team confirmed that the HMAT values actually represent "end-to-end" latency. By comparing these CDAT dump results (which show the device-level latency) with the HMAT numbers, we should have a much clearer picture of whether the massive asymmetry originates from the device firmware itself or from the BIOS calculations. I have attached the extracted CDAT dump results for the devices below. Thanks again for your help in isolating this issue!
