Incorrect L1 data cache reported for Intel Raptor Lake CPU

[jatin-bhateja]

When I run cpuid on my Intel i3 13th Gen Raptor Lake CPU, it reports 48KB of L1D for all 8 logical cores.

According to the Raptor Lake specification, it features 2P and 4E cores, totaling 8 logical cores.

Following is the lscpu dump of my cpu

Here is the output of cpuid

As per the spec on Wikipedia [1] , E-core Gracemont should have 32KB L1D.

Kindly check and resolve.

Only tool which is giving correct information matching to specification is AIDA64 Extreme

I tried querying CPUID EAX=01AH through a c-application, which displays the Processor Type information on Hybrid cores in EAX, but it's not working either.
