Subject[PATCH v2 0/3] Cache id
From: Fenghua Yu <>

This patch set introduces cache id to identify a cache in platform. It can
be useful in such areas as Cach Allocation Technology (CAT) where user
needs to specify how much cache is allocated on which cache. Cache id
provides a concise way to identify the cache. CAT patches will be released

v2: Split one patch into three patches and add ABI documentation.

Fenghua Yu (3):
cacheinfo: Introduce cache id
Documentation, ABI: Add a document entry for cache id
x86, intel_cacheinfo: Enable cache id in x86
