Hi, This patch set introduces a new instruction support on AMD Carrizo (Family 15h, Model 60h-6fh). It adds mwaitx idle function with a configurable timer. The user can configure the idle method and timer value via the idle kernel parameter.
Some discussions of the background, please see: http://marc.info/?l=linux-kernel&m=143202042530498&w=2 http://marc.info/?l=linux-kernel&m=143161327003541&w=2 They are rebased on tip/sched/core. Thanks, Rui Huang Rui (4): x86, mwaitt: add monitorx and mwaitx instruction x86, mwaitt: introduce mwaitx idle with a configurable timer x86, mwaitt: add document to describe mwaitx x86, mwait: fix redundant comment Documentation/kernel-parameters.txt | 10 ++++- arch/x86/include/asm/cpufeature.h | 1 + arch/x86/include/asm/mwait.h | 27 +++++++++++++ arch/x86/include/asm/processor.h | 2 +- arch/x86/kernel/process.c | 81 ++++++++++++++++++++++++++++++++++++- 5 files changed, 118 insertions(+), 3 deletions(-) -- 2.1.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
