cpufrequtils extended with quite some features\n\nCPU power consumption vs performance tuning is no longer\nlimited to CPU frequency switching anymore: deep sleep states,\ntraditional dynamic frequency scaling and hidden turbo/boost\nfrequencies are tied close together and depend on each other.\nThe first two exist on different architectures like PPC, Itanium and\nARM, the latter (so far) only on X86. On X86 the APU (CPU+GPU) will\nonly run most efficiently if CPU and GPU has proper power management\nin place.\n\nUsers and Developers want to have *one* tool to get an overview what\ntheir system supports and to monitor and debug CPU power management\nin detail. The tool should compile and work on as many architectures\nas possible.\n\nOnce this tool stabilizes a bit, it is intended to replace the\nIntel-specific tools in tools/power/x86\n\nSigned-off-by: Dominik Brodowski \u003clinux@dominikbrodowski.net\u003e\n" }, { "commit": "aebdd82e18c38258fe84ea080a43c098e826ef63", "tree": "29172b6857b184d643981b246bcd653cbd8648df", "parents": [ "f01ef569cddb1a8627b1c6b3a134998ad1cf4b22", "250bae8be0177fcc1435cb46d1aba7e40a0366b2" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jul 26 11:10:56 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jul 26 11:10:56 2011 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-ktest\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-ktest:\n ktest: Fix bug when ADD_CONFIG is set but MIN_CONFIG is not\n ktest: Keep fonud configs separate from default configs\n ktest: Add prompt to use OUTPUT_MIN_CONFIG\n ktest: Use Kconfig dependencies to shorten time to make min_config\n ktest: Add test type make_min_config\n ktest: Require one TEST_START in config file\n ktest: Add helper function to avoid duplicate code\n ktest: Add IGNORE_WARNINGS to ignore warnings in some patches\n ktest: Fix tar extracting of modules to target\n ktest: Have the testing tmp dir include machine name\n ktest: Add POST/PRE_BUILD options\n ktest: Allow initrd processing without modules defined\n ktest: Have LOG_FILE evaluate options as well\n ktest: Have wait on stdio honor bug timeout\n ktest: Implement our own force min config\n ktest: Add TEST_NAME option\n ktest: Add CONFIG_BISECT_GOOD option\n ktest: Add detection of triple faults\n ktest: Notify reason to break out of monitoring boot\n" }, { "commit": "c0c463d34adf0c150e5e24fa412fa23f3f7ddc27", "tree": "dfdf2ee7c6bb6662e8aa750c9145618085b092fd", "parents": [ "e72542191cbba4cf7fda21cb22e26b42d7415daf", "a03fc8c375511b6ab43184ab191af3218a919646", "f505c553dbe24b18a8590eb0eb5890a839acd0c3", "a7de915383a6d5c05663f9badbd10d5a87bc1586", "08a4a43fc407d780bdde36d98f89c0dbb2a6be6b" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Jul 23 10:33:08 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Jul 23 10:33:08 2011 -0700" }, "message": "Merge branches \u0027x86-urgent-for-linus\u0027, \u0027core-debug-for-linus\u0027, \u0027irq-core-for-linus\u0027 and \u0027perf-urgent-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027x86-urgent-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n um: Make rwsem.S depend on CONFIG_RWSEM_XCHGADD_ALGORITHM\n\n* \u0027core-debug-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n debug: Make CONFIG_EXPERT select CONFIG_DEBUG_KERNEL to unhide debug options\n\n* \u0027irq-core-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n genirq: Remove unused CHECK_IRQ_PER_CPU()\n\n* \u0027perf-urgent-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n perf tools, x86: Fix 32-bit compile on 64-bit system\n" }, { "commit": "08a4a43fc407d780bdde36d98f89c0dbb2a6be6b", "tree": "2ec7649b3a6423d633508f1a293920d8f5ee8665", "parents": [ "cf6ace16a3cd8b728fb0afa68368fd40bbeae19f" ], "author": { "name": "David Ahern", "email": "dsahern@gmail.com", "time": "Mon Jul 11 15:38:24 2011 -0600" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Jul 21 13:42:30 2011 +0200" }, "message": "perf tools, x86: Fix 32-bit compile on 64-bit system\n\nBuilds for 32-bit perf binaries on a 64-bit host currently fail\nwith this error:\n\n [...]\n bench/../../../arch/x86/lib/memcpy_64.S: Assembler messages:\n bench/../../../arch/x86/lib/memcpy_64.S:29: Error: bad register name `%rdi\u0027\n bench/../../../arch/x86/lib/memcpy_64.S:34: Error: invalid instruction suffix for `movs\u0027\n bench/../../../arch/x86/lib/memcpy_64.S:50: Error: bad register name `%rdi\u0027\n bench/../../../arch/x86/lib/memcpy_64.S:61: Error: bad register name `%rdi\u0027\n ...\n\nThe problem is the detection of the host arch without considering passed in\nflags.

In an AIM7 test, this commit degraded\nperformance by about 40%.\n\nThe commit runs rcu callbacks in a kthread instead of softirq. We observed\nhigh rate of context switch which is caused by this. Out test system has\n64 CPUs and HZ is 1000, so we saw more than 64k context switch per second\nwhich is caused by RCU\u0027s per-CPU kthread. A trace showed that most of\nthe time the RCU per-CPU kthread doesn\u0027t actually handle any callbacks,\nbut instead just does a very small amount of work handling grace periods.\nThis means that RCU\u0027s per-CPU kthreads are making the scheduler do quite\na bit of work in order to allow a very small amount of RCU-related\nprocessing to be done.\n\nAlex Shi\u0027s analysis determined that this slowdown is due to lock\ncontention within the scheduler. Unfortunately, as Peter Zijlstra points\nout, the scheduler\u0027s real-time semantics require global action, which\nmeans that this contention is inherent in real-time scheduling. (Yes,\nperhaps someone will come up with a workaround -- otherwise, -rt is not\ngoing to do well on large SMP systems -- but this patch will work around\nthis issue in the meantime. And \"the meantime\" might well be forever.)\n\nThis patch therefore re-introduces softirq processing to RCU, but only\nfor core RCU work. RCU callbacks are still executed in kthread context,\nso that only a small amount of RCU work runs in softirq context in the\ncommon case. This should minimize ksoftirqd execution, allowing us to\nskip boosting of ksoftirqd for CONFIG_RCU_BOOST\u003dy kernels.\n\nSigned-off-by: Shaohua Li \u003cshaohua.li@intel.com\u003e\nTested-by: \"Alex,Shi\" \u003calex.shi@intel.com\u003e\nSigned-off-by: Paul E.
