Add sysfs controls for edid and performance metrics There are 8 new files exposed in /sys/class/graphics/fb* edid - returns 128 byte edid blog, suitable for parsing with parse-edid metrics_bytes_identical metrics_bytes_rendered metrics_bytes_sent metrics_cpu_kcycles_used metrics_misc and metrics_reset, which resets all perf metrics to zero The 6 perf metrics are of type atomic_t. So these metrics return precise results for short benchmarks, but any test approx a minute or longer runtime may roll over.
