The tests compare IPC statistics that MCA provides with IPC values
measured on Cortex-A55 hardware. For hardware tests, each snippet is
run in a loop unrolled by 1000, and IPC is measured by linux-perf.
Several tests do not match the hardware: the skewed ALU is not
supported, LDR seem to be missing a forwarding path.
Do you actually need --dispatch-stats?
If the goal of these tests is to simply check the IPC, then you should be able to simply pass flags --all-views=false -summary-view.
I also suggest to pass all these tests through the update_mca python script. If you only enable the summary-view, then the number of checks in the output will be very small.
