More specifically, the use of this new MWAITX insn on AMD as a more power-optimal delay function. Patch 3's commit message has details as to how exactly it was measured. The power measurement interface will be part of fam15h_power soon too. Please queue for 4.3. Btw, patch 3 uses rdtsc_ordered() which is in tip/x86/asm... Patch 1 goes to tip/x86/microcode, of course. Thanks. Andrzej Hajda (1): x86/microcode: Use kmemdup() rather than duplicating its implementation Huang Rui (2): x86/asm: Add MONITORX/MWAITX insns support x86/asm: Introduce an MWAITX-based delay with a configurable timer
