      "message": "PM / QoS: add pm_qos_update_request_timeout() API\n\nThe new API, pm_qos_update_request_timeout() is to provide a timeout\nwith pm_qos_update_request.\n\nFor example, pm_qos_update_request_timeout(req, 100, 1000), means that\nQoS request on req with value 100 will be active for 1000 microseconds.\nAfter 1000 microseconds, the QoS request thru req is reset. If there\nwere another pm_qos_update_request(req, x) during the 1000 us, this\nnew request with value x will override as this is another request on the\nsame req handle. A new request on the same req handle will always\noverride the previous request whether it is the conventional request or\nit is the new timeout request.\n\nSigned-off-by: MyungJoo Ham \u003cmyungjoo.ham@samsung.com\u003e\nSigned-off-by: Kyungmin Park \u003ckyungmin.park@samsung.com\u003e\nAcked-by: Mark Gross \u003cmarkgross@thegnar.org\u003e\nSigned-off-by: Rafael J.

      "message": "idle governor: Avoid lock acquisition to read pm_qos before entering idle\n\nThanks to the reviews and comments by Rafael, James, Mark and Andi.\nHere\u0027s version 2 of the patch incorporating your comments and also some\nupdate to my previous patch comments.\n\nI noticed that before entering idle state, the menu idle governor will\nlook up the current pm_qos target value according to the list of qos\nrequests received.  This look up currently needs the acquisition of a\nlock to access the list of qos requests to find the qos target value,\nslowing down the entrance into idle state due to contention by multiple\ncpus to access this list.  The contention is severe when there are a lot\nof cpus waking and going into idle.  For example, for a simple workload\nthat has 32 pair of processes ping ponging messages to each other, where\n64 cpu cores are active in test system, I see the following profile with\n37.82% of cpu cycles spent in contention of pm_qos_lock:\n\n-     37.82%          swapper  [kernel.kallsyms]          [k]\n_raw_spin_lock_irqsave\n   - _raw_spin_lock_irqsave\n      - 95.65% pm_qos_request\n           menu_select\n           cpuidle_idle_call\n         - cpu_idle\n              99.98% start_secondary\n\nA better approach will be to cache the updated pm_qos target value so\nreading it does not require lock acquisition as in the patch below.\nWith this patch the contention for pm_qos_lock is removed and I saw a\n2.2X increase in throughput for my message passing workload.\n\ncc: stable@kernel.org\nSigned-off-by: Tim Chen \u003ctim.c.chen@linux.intel.com\u003e\nAcked-by: Andi Kleen \u003cak@linux.intel.com\u003e\nAcked-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\nAcked-by: mark gross \u003cmarkgross@thegnar.org\u003e\nSigned-off-by: Len Brown \u003clen.brown@intel.com\u003e\n"

      "message": "llseek: automatically add .llseek fop\n\nAll file_operations should get a .llseek operation so we can make\nnonseekable_open the default for future file operations without a\n.llseek pointer.\n\nThe three cases that we can automatically detect are no_llseek, seq_lseek\nand default_llseek. For cases where we can we can automatically prove that\nthe file offset is always ignored, we use noop_llseek, which maintains\nthe current behavior of not returning an error from a seek.\n\nNew drivers should normally not use noop_llseek but instead use no_llseek\nand call nonseekable_open at open time.  Existing drivers can be converted\nto do the same when the maintainer knows for certain that no user code\nrelies on calling seek on the device file.\n\nThe generated code is often incorrectly indented and right now contains\ncomments that clarify for each added line why a specific variant was\nchosen. In the version that gets submitted upstream, the comments will\nbe gone and I will manually fix the indentation, because there does not\nseem to be a way to do that using coccinelle.\n\nSome amount of new code is currently sitting in linux-next that should get\nthe same modifications, which I will do at the end of the merge window.\n\nMany thanks to Julia Lawall for helping me learn to write a

      "message": "pm qos infrastructure and interface\n\nThe following patch is a generalization of the latency.c implementation done\nby Arjan last year.  It provides infrastructure for more than one parameter,\nand exposes a user mode interface for processes to register pm_qos\nexpectations of processes.\n\nThis interface provides a kernel and user mode interface for registering\nperformance expectations by drivers, subsystems and user space applications on\none of the parameters.\n\nCurrently we have {cpu_dma_latency, network_latency, network_throughput} as\nthe initial set of pm_qos parameters.\n\nThe infrastructure exposes multiple misc device nodes one per implemented\nparameter.  The set of parameters implement is defined by pm_qos_power_init()\nand pm_qos_params.h.  This is done because having the available parameters\nbeing runtime configurable or changeable from a driver was seen as too easy to\nabuse.\n\nFor each parameter a list of performance requirements is maintained along with\nan aggregated target value.  The aggregated target value is updated with\nchanges to the requirement list or elements of the list.  Typically the\naggregated target value is simply the max or min of the requirement values\nheld in the parameter list elements.\n\n\u003eFrom kernel mode the use of this interface is simple:\n\npm_qos_add_requirement(param_id, name, target_value):\n\n  Will insert a named element in the list for that identified PM_QOS\n  parameter with the target value.  Upon change to this list the new target is\n  recomputed and any registered notifiers are called only if the target value\n  is now different.\n\npm_qos_update_requirement(param_id, name, new_target_value):\n\n  Will search the list identified by the param_id for the named list element\n  and then update its target value, calling the notification tree if the\n  aggregated target is changed.  with that name is already registered.\n\npm_qos_remove_requirement(param_id, name):\n\n  Will search the identified list for the named element and remove it, after\n  removal it will update the aggregate target and call the notification tree\n  if the target was changed as a result of removing the named requirement.\n\n\u003eFrom user mode:\n\n  Only processes can register a pm_qos requirement.  To provide for\n  automatic cleanup for process the interface requires the process to register\n  its parameter requirements in the following way:\n\n  To register the default pm_qos target for the specific parameter, the\n  process must open one of /dev/[cpu_dma_latency, network_latency,\n  network_throughput]\n\n  As long as the device node is held open that process has a registered\n  requirement on the parameter.  The name of the requirement is\n  \"process_\u003cPID\u003e\" derived from the current-\u003epid from within the open system\n  call.\n\n  To change the requested target value the process needs to write a s32\n  value to the open device node.  This translates to a\n  pm_qos_update_requirement call.\n\n  To remove the user mode request for a target value simply close the device\n  node.\n\n[akpm@linux-foundation.org: fix warnings]\n[akpm@linux-foundation.org: fix build]\n[akpm@linux-foundation.org: fix build again]\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: mark gross \u003cmgross@linux.intel.com\u003e\nCc: \"John W.
