How do I calculate the number of TLB entries on an Arrowlake Intel(R) Core(TM) Ultra 9 285K

[Colin-Ian-King]

I'm trying to determine the exact number of TLB entries on an Arrowlake Ultra 9 285K via cpuid but I'm not getting the correct values. What's the recommended recipe for these newer processors?

Hi Colin-Ian-King,

Greetings from Intel Customer Support.

Thank you for your patience.

As P-cores and E-cores have different TLB structures, we would like to gather some additional information to further investigate and assist you with a possible solution.

Could you please provide the following details:

• The CPUID values you are currently obtaining
• The expected values you believe should be returned (if available)
• Details about the operating system you are using (including distribution and version)

As you mentioned using CPUID, we understand you may be working on a Linux-based system; however, we kindly request confirmation of the exact OS details to proceed accurately.

Once we have this information, we will continue our investigation and assist you further.

Thank you for your time and cooperation. We look forward to your response.

Best regards,

Roy
