Fenghua Yu 9124130573 x86/cpufeatures: Enumerate cldemote instruction ... cldemote is a new instruction in future x86 processors. It hints to hardware that a specified cache line should be moved ("demoted") from the cache(s) closest to the processor core to a level more distant from the processor core. This instruction is faster than snooping to make the cache line available for other cores. cldemote instruction is indicated by the presence of the CPUID feature flag CLDEMOTE (CPUID.(EAX=0x7, ECX=0):ECX[bit25]). More details on cldemote instruction can be found in the latest Intel Architecture Instruction Set Extensions and Future Features Programming Reference.
