Hi.
I am trying to measure the load of individual components, such as a decoder, encoder and vic.
I found the file /sys/kernel/debug/tegra_host/status_all
It has the following lines:
---- mlocks ----
---- syncpts ----
id 22 (15340000.vic_6_dirty_cpu_sch_0) min 47082 max 47082 refs 1 (previous client : 15340000.vic_6_dirty_cpu_sch_0)

What do these numbers and names mean? How can this be used for workload measurements?
