Type of Intel Broadwell processor that supports 16 COS registers

As far as I know, the Intel Processor D (previously called Broadwell processor) can support at most 16 COS registers for the http://wiki.xenproject.org/wiki/Intel_Platform_QoS_Technologies# Cache_Allocation_Technology cache allocation technology. So I want to purchase a computer that has 16 COS registers on its Intel CPU.

According to http://www.intel.com/content/dam/www/public/us/en/documents/manuals/64-ia-32-architectures-software-developers-manual.pdf Intel's manual, the maximum number of COS registers is stored in the lower 16 bits of the EDX register as the output of the CPUID.(EAX=10H, ECX=ResID=1) instruction.

My question is:

1) Does anyone know which type of Intel Processor D can support 16 COS registers?

(If you happen to have a Processor D processor, I really appreciate it if you could run the cpuidinstruction and post the output of the cpuid.)

2) Can I use the cache allocation technology on a desktop computer with the Processor D CPU?

I searched around for a long time but didn't find any place that list this type of information. :-(

Thank you very much for your time and help!
