[edk2-devel] [PATCH 0/1] UefiCpuPkg: Correct the count of different type of Cache.

[Yuanhao Xie]

This patch fixes an error in calculating cache sizes for cores from
different Dies. The original code incorrectly cleared cache sizes for
different core types during intermediate calculation steps, leading to
mistakes in counting duplicate entries. This patch adds a check for
cache size to distinguish between different cache types.
