Thanks a lot for exploring more CPU variants which share the same data source packet format.
The latest Linux kernel have defined the CPU part number and MIDR for below CPU variants:
- A78 - X1 - A715 - A78C
I would like to use a patch to support these CPUs in perf tool. Given other CPU variants (X3/V2/A720) have not been supported in the kernel, and so far no one requests them, I would like leave them out.
Please let me know if this okay for you or not.
