[RFC PATCH v2 QEMU 2/4] hw/cxl: Add emulation of a CXL Hotness Monitoring Unit (CHMU)

CXL r3.2 defines a CXL Hotness Monitoring Unit. This allows for a CXL device to do on device estimation of which 'granuals' of data are 'hot' - that is accessed a lot. For a typical application hot data on a CXL device both wastes potentially limited bandwidth and many have latency impacts. Access

[RFC PATCH v2 QEMU 3/4] hw/cxl: Provide a means to get the interleave set position for an EP

CXL interleave decoding is hieriarchical in a fashion that means the CXL memory devices only need to know the interleave granularity and interleave ways to figure out which address bits to drop from incoming translactions. Unfortunately to provide the right information to the hotness monitoring plu
