From: Dave Jiang <dave.ji...@intel.com>
According to ACPI spec 6.5 5.2.28.4 System Locality Latency and Bandwidth
Information Structure, if the "Entry Base Unit" is 1024 for BW and the
matrix entry has the value of 100, the BW is 100 GB/s. So the
entry_base_unit should be changed from 1000 to 1024 given the comment notes
it's 16GB/s for .latency_bandwidth.
