Included are intel_idle and turbostat updates from Len Brown (these have been in linux-next for quite some time), a new cpufreq driver for powernv (that might spend some more time in linux-next, but BenH was asking me so nicely to push it for 3.15 that I couldn't resist), some cpufreq fixes and cleanups (including fixes for some silly breakage in a couple of cpufreq drivers introduced during the 3.14 cycle), assorted ACPI cleanups, wakeup framework documentation fixes, a new sysfs attribute for cpuidle and a new command line argument for power domains diagnostics. Specifics: - Fix for a recently introduced CPU hotplug regression in ARM KVM from Ming Lei. - Fixes for breakage in the at32ap, loongson2_cpufreq, and unicore32 cpufreq drivers introduced during the 3.14 cycle (-stable material) from Chen Gang and Viresh Kumar. - New powernv cpufreq driver from Vaidyanathan Srinivasan, with bits from Gautham R Shenoy and Srivatsa S Bhat. - Exynos cpufreq driver fix preventing it from being included into multiplatform builds that aren't supported by it from Sachin Kamat. - cpufreq cleanups related to the usage of the driver_data field in struct cpufreq_frequency_table from Viresh Kumar. - cpufreq ppc driver cleanup from Sachin Kamat. - Intel BayTrail support for intel_idle and ACPI idle from Len Brown. - Intel CPU model 54 (Atom N2000 series) support for intel_idle from Jan Kiszka. - intel_idle fix for Intel Ivy Town residency targets from Len Brown. - turbostat updates (Intel Broadwell support and output cleanups) from Len Brown. - New cpuidle sysfs attribute for exporting C-states' target residency information to user space from Daniel Lezcano. - New kernel command line argument to prevent power domains enabled by the bootloader from being turned off even if they are not in use (for diagnostics purposes) from Tushar Behera. - Fixes for wakeup sysfs attributes documentation from Geert Uytterhoeven. - New ACPI video blacklist entry for ThinkPad Helix from Stephen Chandler Paul. - Assorted ACPI cleanups and a Kconfig help update from Jonghwan Choi, Zhihui Zhang, Hanjun Guo" * tag 'pm+acpi-3.15-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (28 commits) ACPI: Update the ACPI spec information in Kconfig arm, kvm: fix double lock on cpu_add_remove_lock cpuidle: sysfs: Export target residency information cpufreq: ppc: Remove duplicate inclusion of fsl_soc.h cpufreq: create another field .flags in cpufreq_frequency_table cpufreq: use kzalloc() to allocate memory for cpufreq_frequency_table cpufreq: don't print value of .driver_data from core cpufreq: ia64: don't set .driver_data to index cpufreq: powernv: Select CPUFreq related Kconfig options for powernv cpufreq: powernv: Use cpufreq_frequency_table.driver_data to store pstate ids cpufreq: powernv: cpufreq driver for powernv platform cpufreq: at32ap: don't declare local variable as static cpufreq: loongson2_cpufreq: don't declare local variable as static cpufreq: unicore32: fix typo issue for 'clk' cpufreq: exynos: Disable on multiplatform build PM / wakeup: Correct presence vs. emptiness of wakeup_* attributes PM / domains: Add pd_ignore_unused to keep power domains enabled ACPI / dock: Drop dock_device_ids[] table ACPI / video: Favor native backlight interface for ThinkPad Helix ACPI / thermal: Fix wrong variable usage in debug statement ...

We don't fit into 80 columns on most machines, so keep the format simple. Print frequency in MHz instead of GHz. We've got 8 columns now, so use them to show low frequency in a more natural unit. Many users didn't understand what %c0 meant, so re-name it to be %Busy. Add Avg_MHz column, which is the frequency that many users expect to see -- the total number of cycles executed over the measurement interval. People found the previous GHz to be confusing, since it was the speed only over the non-idle interval. That measurement has been re-named Bzy_MHz. Suggested-by: Dirk J.

It maps chunk of file, marks VMA as MADV_RANDOM to turn off readahead, pokes VMA via mincore() to determine cached pages, triggers page-fault only for them, and finally gathers information via pagemap/kpageflags. Before unmap it marks VMA as MADV_SEQUENTIAL for ignoring reference bits. usage: page-types -f <path> If <path> is directory it will analyse all files in all subdirectories. Symlinks are not followed as well as mount points. Hardlinks aren't handled, they'll be dumped as many times as they are found. Recursive walk brings all dentries into dcache and populates page cache of block-devices aka 'Buffers'. Probably it's worth to add ioctl for dumping file page cache as array of PFNs as a replacement for this hackish juggling with mmap/madvise/mincore/pagemap. Also recursive walk could be replaced with dumping cached inodes via some ioctl or debugfs interface followed by openning them via open_by_handle_at, this would fix hardlinks handling and unneeded population of dcache and buffers. This interface might be used as data source for constructing readahead plans and for background optimizations of actively used files. collateral changes: + fix 64-bit LFS: define _FILE_OFFSET_BITS instead of _LARGEFILE64_SOURCE + replace lseek + read with single pread + make show_page_range() reusable after flush usage example: ~/src/linux/tools/vm$ sudo ./page-types -L -f page-types foffset offset flags page-types Inode: 2229277 Size: 89065 (22 pages) Modify: Tue Feb 25 12:00:59 2014 (162 seconds ago) Access: Tue Feb 25 12:01:00 2014 (161 seconds ago) 0 3cbf3b __RU_lA____M________________________ 1 38946a __RU_lA____M________________________ 2 1a3cec __RU_lA____M________________________ 3 1a8321 __RU_lA____M________________________ 4 3af7cc __RU_lA____M________________________ 5 1ed532 __RU_lA_____________________________ 6 2e436a __RU_lA_____________________________ 7 29a35e ___U_lA_____________________________ 8 2de86e ___U_lA_____________________________ 9 3bdfb4 ___U_lA_____________________________ 10 3cd8a3 ___U_lA_____________________________ 11 2afa50 ___U_lA_____________________________ 12 2534c2 ___U_lA_____________________________ 13 1b7a40 ___U_lA_____________________________ 14 17b0be ___U_lA_____________________________ 15 392b0c ___U_lA_____________________________ 16 3ba46a __RU_lA_____________________________ 17 397dc8 ___U_lA_____________________________ 18 1f2a36 ___U_lA_____________________________ 19 21fd30 __RU_lA_____________________________ 20 2c35ba __RU_l______________________________ 21 20f181 __RU_l______________________________ flags page-count MB symbolic-flags long-symbolic-flags 0x000000000000002c 2 0 __RU_l______________________________ referenced,uptodate,lru 0x0000000000000068 11 0 ___U_lA_____________________________ uptodate,lru,active 0x000000000000006c 4 0 __RU_lA_____________________________ referenced,uptodate,lru,active 0x000000000000086c 5 0 __RU_lA____M________________________ referenced,uptodate,lru,active,mmap total 22 0 ~/src/linux/tools/vm$ sudo ./page-types -f / flags page-count MB symbolic-flags long-symbolic-flags 0x0000000000000028 21761 85 ___U_l______________________________ uptodate,lru 0x000000000000002c 127279 497 __RU_l______________________________ referenced,uptodate,lru 0x0000000000000068 74160 289 ___U_lA_____________________________ uptodate,lru,active 0x000000000000006c 84469 329 __RU_lA_____________________________ referenced,uptodate,lru,active 0x000000000000007c 1 0 __RUDlA_____________________________ referenced,uptodate,dirty,lru,active 0x0000000000000228 370 1 ___U_l___I__________________________ uptodate,lru,reclaim 0x0000000000000828 49 0 ___U_l_____M________________________ uptodate,lru,mmap 0x000000000000082c 126 0 __RU_l_____M________________________ referenced,uptodate,lru,mmap 0x0000000000000868 137 0 ___U_lA____M________________________ uptodate,lru,active,mmap 0x000000000000086c 12890 50 __RU_lA____M________________________ referenced,uptodate,lru,active,mmap total 321242 1254 Signed-off-by: Konstantin Khlebnikov <koct9i@gmail.com> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Fengguang Wu <fengguang.wu@intel.com> Cc: Borislav Petkov <bp@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This is the main pull request with most of the work for this merge window. I will describe it a bit more further down. There is some additional cpuidle driver work, however I haven't included it in this tree as it depends on some work in tip/timer-core which Thomas accidentally forgot to put in a topic branch. Since I didn't want to carry all of that tip timer stuff in powerpc -next, I setup a separate branch on top of Thomas tree with just that cpuidle driver in it, and Stephen has been carrying that in next separately for a while now. I'll send a separate pull request for it. Additionally, two new pieces in this tree add users for a sysfs API that Tejun and Greg have been deprecating in drivers-core-next. Thankfully Greg reverted the patch that removes the old API so this merge can happen cleanly, but once merged, I will send a patch adjusting our new code to the new API so that Greg can send you the removal patch. Now as for the content of this branch, we have a lot of perf work for power8 new counters including support for our new "nest" counters (also called 24x7) under pHyp (not natively yet). We have new functionality when running under the OPAL firmware (non-virtualized or KVM host), such as access to the firmware error logs and service processor dumps, system parameters and sensors, along with a hwmon driver for the latter. There's also a bunch of bug fixes accross the board, some LE fixes, and a nice set of selftests for validating our various types of copy loops. On the Freescale side, we see mostly new chip/board revisions, some clock updates, better support for machine checks and debug exceptions, etc..." * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (70 commits) powerpc/book3s: Fix CFAR clobbering issue in machine check handler. powerpc/compat: 32-bit little endian machine name is ppcle, not ppc powerpc/le: Big endian arguments for ppc_rtas() powerpc: Use default set of netfilter modules (CONFIG_NETFILTER_ADVANCED=n) powerpc/defconfigs: Enable THP in pseries defconfig powerpc/mm: Make sure a local_irq_disable prevent a parallel THP split powerpc: Rate-limit users spamming kernel log buffer powerpc/perf: Fix handling of L3 events with bank == 1 powerpc/perf/hv_{gpci, 24x7}: Add documentation of device attributes powerpc/perf: Add kconfig option for hypervisor provided counters powerpc/perf: Add support for the hv 24x7 interface powerpc/perf: Add support for the hv gpci (get performance counter info) interface powerpc/perf: Add macros for defining event fields & formats powerpc/perf: Add a shared interface to get gpci version and capabilities powerpc/perf: Add 24x7 interface headers powerpc/perf: Add hv_gpci interface header powerpc: Add hvcalls for 24x7 and gpci (Get Performance Counter Info) sysfs: create bin_attributes under the requested group powerpc/perf: Enable BHRB access for EBB events powerpc/perf: Add BHRB constraint and IFM MMCRA handling for EBB ...

In V4 version of the patch I have addressed all of Olaf's most recent set of comments/concerns. In V5 version of the patch I had addressed Greg's most recent comments. I would like to thank Greg for suggesting that I use misc device; it has significantly simplified the code. In V6 version of the patch I have cleaned up error message based on Olaf's comments. I have also rebased the patch based on the current tip. In this version of the patch, I have addressed the latest comments from Greg. Signed-off-by: K. Y.

We also need to make sure we only update al->filtered after thread__find_addr_map(), because there is where al->filtered gets initialized to zero. This will increase the cost of processing when all we don't need this toggling, but will provide flexibility for the TUI and GTK+ interfaces, that will incur in creating the hist_entries just once.

This is because it took that long to gather about 10,000 thread maps and process them. I don't think a user wants to wait that long. Instead, recognize that thread maps are roughly equivalent to pid maps and just quickly copy those instead. To do this, I synthesize 'fork' events, this eventually calls thread__fork() and copies the maps over. The overhead goes from 15 minutes down to about a few seconds. -- V2: based on Jiri's comments, moved malloc up a level and made sure the memory was freed Signed-off-by: Don Zickus <dzickus@redhat.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Joe Mario <jmario@redhat.com> Link: http://lkml.kernel.org/r/1394808224-113774-1-git-send-email-dzickus@redhat.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

In order to do this, introduce parse_options_subcommand() for handling subcommands as a special case in the parse-options machinery.

Unfortunately, that field is a bit mask, so it is hard to interpret as a decimal. Print in hex, so the user can easily see what bits are set and more importantly what type of info it is conveying.
