Re: CAT definition in the scenario xmls

I mean you can get L3 caches info from CPUID first.

 

And then you can try cmd in ACRN console:

  rdmsr 0xc90

 

or wrmsr 0xc90 0x0ff

 

thanks!

Hi Minggui,

The settings that i set in wrmsr through ACRN console is working

Below is the xmls that i trying to set, but its weird that ACRN is not booting up after i change the value in xmls.
