Hello.
I would like to ask if it is possible to read the PMU of core0 from core1.
So far i have work with an one core CPU and i use the MRS, MSR instructions to set the PMU.
How to enable the PMUs for each core?
Also, i read the PMUs are memory mapped so i suppose there is a way to read them from another core.
Could someone provide me some information on how to do it with memory mapped or if there is a simple way.
Thank you

Did you try it and it did not work? Or didn't you try at all?
No i dint try yet. I experiment by using the pmu in one core and it works. I wanted to verify first if it is possible. I read that the cpu must be in debug state to do this but in the TPM it dont says anything like this.
You are kidding? Before asking, you should try,
