Over time its semantics have changed, and it now\nindicates whether or not we are booted on an EFI machine with\nbit-native firmware, e.g. 64-bit kernel with 64-bit firmware.\n\nThe immediate motivation for this patch is the bug report at,\n\n https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557\n\nwhich details how running a platform driver on an EFI machine that is\ndesigned to run under BIOS can cause the machine to become\nbricked. Also, the following report,\n\n https://bugzilla.kernel.org/show_bug.cgi?id\u003d47121\n\ndetails how running said driver can also cause Machine Check\nExceptions. Drivers need a new means of detecting whether they\u0027re\nrunning on an EFI machine, as sadly the expression,\n\n if (!efi_enabled)\n\nhasn\u0027t been a sufficient condition for quite some time.\n\nUsers actually want to query \u0027efi_enabled\u0027 for different reasons -\nwhat they really want access to is the list of available EFI\nfacilities.\n\nFor instance, the x86 reboot code needs to know whether it can invoke\nthe ResetSystem() function provided by the EFI runtime services, while\nthe ACPI OSL code wants to know whether the EFI config tables were\nmapped successfully. There are also checks in some of the platform\ndriver code to simply see if they\u0027re running on an EFI machine (which\nwould make it a bad idea to do BIOS-y things).\n\nThis patch is a prereq for the samsung-laptop fix patch.\n\nCc: David Airlie \u003cairlied@linux.ie\u003e\nCc: Corentin Chary \u003ccorentincj@iksaif.net\u003e\nCc: Matthew Garrett \u003cmjg59@srcf.ucam.org\u003e\nCc: Dave Jiang \u003cdave.jiang@intel.com\u003e\nCc: Olof Johansson \u003colof@lixom.net\u003e\nCc: Peter Jones \u003cpjones@redhat.com\u003e\nCc: Colin Ian King \u003ccolin.king@canonical.com\u003e\nCc: Steve Langasek \u003csteve.langasek@canonical.com\u003e\nCc: Tony Luck \u003ctony.luck@intel.com\u003e\nCc: Konrad Rzeszutek Wilk \u003ckonrad@kernel.org\u003e\nCc: Rafael J.

The priority of these\ntasks is set to 49 by default. If user launches an RT FIFO task\nwith priority lower than 49 of softirq RT tasks, it\u0027s possible\nthere are two RT FIFO tasks enqueued one cpu runqueue at one\nmoment. By current strategy of balancing RT tasks, when it comes\nto RT tasks, we really need to put them off to a CPU that they\ncan run on as soon as possible. Even if it means a bit of cache\nline flushing, we want RT tasks to be run with the least latency.\n\nWhen the user RT FIFO task which just launched before is\nrunning, the sched timer tick of the current cpu happens. In this\ntick period, the timeout value of the user RT task will be\nupdated once. Subsequently, we try to wake up one softirq RT\ntask on its local cpu. As the priority of current user RT task\nis lower than the softirq RT task, the current task will be\npreempted by the higher priority softirq RT task. Before\npreemption, we check to see if current can readily move to a\ndifferent cpu. If so, we will reschedule to allow the RT push logic\nto try to move current somewhere else. Whenever the woken\nsoftirq RT task runs, it first tries to migrate the user FIFO RT\ntask over to a cpu that is running a task of lesser priority. If\nmigration is done, it will send a reschedule request to the found\ncpu by IPI interrupt. Once the target cpu responds the IPI\ninterrupt, it will pick the migrated user RT task to preempt its\ncurrent task. When the user RT task is running on the new cpu,\nthe sched timer tick of the cpu fires. So it will tick the user\nRT task again. This also means the RT task timeout value will be\nupdated again. As the migration may be done in one tick period,\nit means the user RT task timeout value will be updated twice\nwithin one tick.\n\nIf we set a limit on the amount of cpu time for the user RT task\nby setrlimit(RLIMIT_RTTIME), the SIGXCPU signal should be posted\nupon reaching the soft limit.\n\nBut exactly when the SIGXCPU signal should be sent depends on the\nRT task timeout value. In fact the timeout mechanism of sending\nthe SIGXCPU signal assumes the RT task timeout is increased once\nevery tick.\n\nHowever, currently the timeout value may be added twice per\ntick. So it results in the SIGXCPU signal being sent earlier\nthan expected.\n\nTo solve this issue, we prevent the timeout value from increasing\ntwice within one tick time by remembering the jiffies value of\nlast updating the timeout. As long as the RT task\u0027s jiffies is\ndifferent with the global jiffies value, we allow its timeout to\nbe updated.\n\nSigned-off-by: Ying Xue \u003cying.xue@windriver.com\u003e\nSigned-off-by: Fan Du \u003cfan.du@windriver.com\u003e\nReviewed-by: Yong Zhang \u003cyong.zhang0@gmail.com\u003e\nAcked-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: \u003cpeterz@infradead.org\u003e\nLink: http://lkml.kernel.org/r/1342508623-2887-1-git-send-email-ying.xue@windriver.com\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\n" }, { "commit": "1496ec13a1ae92cea305d266ff73f850138f92c7", "tree": "906a88476ca654e6446502c83882b76ef067ae80", "parents": [ "ba2ab41f3d68f277860768b2c5b197768b196332", "3836414f45b01486b9b50c627a329010573ad0f4" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 24 12:42:50 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 24 12:42:50 2013 -0800" }, "message": "Merge tag \u0027fixes-for-linus2\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc\n\nPull ARM SoC fixes from Olof Johansson:\n \"Here\u0027s a long-pending fixes pull request for arm-soc (I didn\u0027t send\n one in the -rc4 cycle).\n\n The larger deltas are from:\n\n - A fixup of error paths in the mvsdio driver\n\n - Header file move for a driver that hadn\u0027t been properly converted\n to multiplatform on i.MX, which was causing build failures when\n included\n\n - Device tree updates for at91 dealing mostly with their new pinctrl\n setup merged in 3.8 and mistakes in those initial configs\n\n The rest are the normal mix of small fixes all over the place; sunxi,\n omap, imx, mvebu, etc, etc.\"\n\n* tag \u0027fixes-for-linus2\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (40 commits)\n mfd: vexpress-sysreg: Don\u0027t skip initialization on probe\n ARM: vexpress: Enable A7 cores in V2P-CA15_A7\u0027s Device Tree\n ARM: vexpress: extend the MPIDR range used for pen release check\n ARM: at91/dts: correct comment in at91sam9x5.dtsi for mii\n ARM: at91/at91_dt_defconfig: add at91sam9n12 SoC to DT defconfig\n ARM: at91/at91_dt_defconfig: remove memory specification to cmdline\n ARM: at91/dts: add macb mii pinctrl config for kizbox\n ARM: at91: rm9200: remake the BGA as default version\n ARM: at91: fix gpios on i2c-gpio for RM9200 DT\n ARM: at91/at91sam9x5 DTS: add SCK USART pins\n ARM: at91/at91sam9x5 DTS: correct wrong PIO BANK values on u(s)arts\n ARM: at91/at91-pinctrl documentation: fix typo and add some details\n ARM: kirkwood: fix missing #interrupt-cells property\n mmc: mvsdio: use devm_ API to simplify/correct error paths.\n clk: mvebu/clk-cpu.c: fix memory leakage\n ARM: OMAP2+: omap4-panda: add UART2 muxing for WiLink shared transport\n ARM: OMAP2+: DT node Timer iteration fix\n ARM: OMAP2+: Fix section warning for omap_init_ocp2scp()\n ARM: OMAP2+: fix build break for omapdrm\n ARM: OMAP2: Fix missing omap2xxx_clkt_vps_late_init function calls\n ...\n" }, { "commit": "b878e7fb22ea48b0585bbbbef249f7efc6d42748", "tree": "585cb9287822106aca7769e5495a37cc663c53f6", "parents": [ "d0528b5d71faf612014dd7672e44225c915344b2" ], "author": { "name": "Vince Weaver", "email": "vincent.weaver@maine.edu", "time": "Tue Jan 08 14:44:25 2013 -0500" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Thu Jan 24 16:40:19 2013 -0300" }, "message": "perf: Missing field in PERF_RECORD_SAMPLE documentation\n\nWhile trying to write a perf_event/mmap test for my perf_event\ntest-suite I came across a missing field description in the\nPERF_RECORD_SAMPLE documentation in perf_event.h\n\nSigned-off-by: Vince Weaver \u003cvincent.weaver@maine.edu\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLink: http://lkml.kernel.org/r/alpine.DEB.2.02.1301081439300.24507@vincent-weaver-1.um.maine.edu\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "54a3ac0c9e5b7213daa358ce74d154352657353a", "tree": "ea13854ac6bf7ad3bf8f55225c6d4d39206e463c", "parents": [ "58b2939b4d5a030eaec469d29812ab8477ee7e76" ], "author": { "name": "Lan Tianyu", "email": "tianyu.lan@intel.com", "time": "Thu Jan 24 10:31:28 2013 +0800" }, "committer": { "name": "Sarah Sharp", "email": "sarah.a.sharp@linux.intel.com", "time": "Thu Jan 24 09:58:18 2013 -0800" }, "message": "usb: Using correct way to clear usb3.0 device\u0027s remote wakeup feature.\n\nUsb3.0 device defines function remote wakeup which is only for interface\nrecipient rather than device recipient.

That\u0027s 16% of the\nbuffer wasted. A million events will add 4 megs of white space\ninto the buffer.\n\nIt was later noticed that PowerTop v2beta could not work on systems\nwhere the kernel was 64 bit but the userspace was 32 bits.\nThe reason was because the offsets are different between the\ntwo and the hard coded offset of one would not work with the other.\n\nWith PowerTop v2 final, it implemented the same interface that both\nperf and trace-cmd use. That is, it reads the format file of\nthe event to find the offsets of the fields it needs. This fixes\nthe problem with running powertop on a 32 bit userspace running\non a 64 bit kernel.
