EMC Log Utility

The emc_log utility enables you to perform memory bandwidth analysis of the system. The utility performs statistical sampling of memory controller usage on a client-by-client basis and reports output using stdout. Orin platforms provide two memory controller (MC) statistic counters and one embedded memory controller (EMC) counter. Software generally uses one of the MC counters and the EMC counter. If multiple clients are supplied, the emc_log utility samples them two at a time in a round-robin fashion.
