Introduction -2. Why cmwq? -3. The Design -4. Application Programming Interface (API) -5. Example Execution Scenarios -6. Guidelines - - -1. Introduction - -There are many cases where an asynchronous process execution context -is needed and the workqueue (wq) API is the most commonly used -mechanism for such cases. - -When such an asynchronous execution context is needed, a work item -describing which function to execute is put on a queue. An -independent thread serves as the asynchronous execution context. The -queue is called workqueue and the thread is called worker. - -While there are work items on the workqueue the worker executes the -functions associated with the work items one after the other. When -there is no work item left on the workqueue the worker becomes idle. -When a new work item gets queued, the worker begins executing again. - - -2. Why cmwq? - -In the original wq implementation, a multi threaded (MT) wq had one -worker thread per CPU and a single threaded (ST) wq had one worker -thread system-wide. A single MT wq needed to keep around the same -number of workers as the number of CPUs. The kernel grew a lot of MT -wq users over the years and with the number of CPU cores continuously -rising, some systems saturated the default 32k PID space just booting -up. - -Although MT wq wasted a lot of resource, the level of concurrency -provided was unsatisfactory. The limitation was common to both ST and -MT wq albeit less severe on MT. Each wq maintained its own separate -worker pool. A MT wq could provide only one execution context per CPU -while a ST wq one for the whole system. Work items had to compete for -those very limited execution contexts leading to various problems -including proneness to deadlocks around the single execution context. - -The tension between the provided level of concurrency and resource -usage also forced its users to make unnecessary tradeoffs like libata -choosing to use ST wq for polling PIOs and accepting an unnecessary -limitation that no two polling PIOs can progress at the same time. As -MT wq don't provide much better concurrency, users which require -higher level of concurrency, like async or fscache, had to implement -their own thread pool. - -Concurrency Managed Workqueue (cmwq) is a reimplementation of wq with -focus on the following goals. - -* Maintain compatibility with the original workqueue API. - -* Use per-CPU unified worker pools shared by all wq to provide - flexible level of concurrency on demand without wasting a lot of - resource. - -* Automatically regulate worker pool and level of concurrency so that - the API users don't need to worry about such details. - - -3. The Design - -In order to ease the asynchronous execution of functions a new -abstraction, the work item, is introduced. - -A work item is a simple struct that holds a pointer to the function -that is to be executed asynchronously. Whenever a driver or subsystem -wants a function to be executed asynchronously it has to set up a work -item pointing to that function and queue that work item on a -workqueue. - -Special purpose threads, called worker threads, execute the functions -off of the queue, one after the other. If no work is queued, the -worker threads become idle. These worker threads are managed in so -called thread-pools. - -The cmwq design differentiates between the user-facing workqueues that -subsystems and drivers queue work items on and the backend mechanism -which manages thread-pool and processes the queued work items. - -The backend is called gcwq. There is one gcwq for each possible CPU -and one gcwq to serve work items queued on unbound workqueues. - -Subsystems and drivers can create and queue work items through special -workqueue API functions as they see fit. They can influence some -aspects of the way the work items are executed by setting flags on the -workqueue they are putting the work item on. These flags include -things like CPU locality, reentrancy, concurrency limits and more. To -get a detailed overview refer to the API description of -alloc_workqueue() below. - -When a work item is queued to a workqueue, the target gcwq is -determined according to the queue parameters and workqueue attributes -and appended on the shared worklist of the gcwq. For example, unless -specifically overridden, a work item of a bound workqueue will be -queued on the worklist of exactly that gcwq that is associated to the -CPU the issuer is running on. - -For any worker pool implementation, managing the concurrency level -(how many execution contexts are active) is an important issue. cmwq -tries to keep the concurrency at a minimal but sufficient level. -Minimal to save resources and sufficient in that the system is used at -its full capacity. - -Each gcwq bound to an actual CPU implements concurrency management by -hooking into the scheduler. The gcwq is notified whenever an active -worker wakes up or sleeps and keeps track of the number of the -currently runnable workers. Generally, work items are not expected to -hog a CPU and consume many cycles. That means maintaining just enough -concurrency to prevent work processing from stalling should be -optimal. As long as there are one or more runnable workers on the -CPU, the gcwq doesn't start execution of a new work, but, when the -last running worker goes to sleep, it immediately schedules a new -worker so that the CPU doesn't sit idle while there are pending work -items. This allows using a minimal number of workers without losing -execution bandwidth. - -Keeping idle workers around doesn't cost other than the memory space -for kthreads, so cmwq holds onto idle ones for a while before killing -them. - -For an unbound wq, the above concurrency management doesn't apply and -the gcwq for the pseudo unbound CPU tries to start executing all work -items as soon as possible. The responsibility of regulating -concurrency level is on the users. There is also a flag to mark a -bound wq to ignore the concurrency management. Please refer to the -API section for details. - -Forward progress guarantee relies on that workers can be created when -more execution contexts are necessary, which in turn is guaranteed -through the use of rescue workers. All work items which might be used -on code paths that handle memory reclaim are required to be queued on -wq's that have a rescue-worker reserved for execution under memory -pressure. Else it is possible that the thread-pool deadlocks waiting -for execution contexts to free up. - - -4. Application Programming Interface (API) - -alloc_workqueue() allocates a wq. The original create_*workqueue() -functions are deprecated and scheduled for removal. alloc_workqueue() -takes three arguments - @name, @flags and @max_active. @name is the -name of the wq and also used as the name of the rescuer thread if -there is one. - -A wq no longer manages execution resources but serves as a domain for -forward progress guarantee, flush and work item attributes. @flags -and @max_active control how work items are assigned execution -resources, scheduled and executed. - -@flags: - - WQ_NON_REENTRANT - - By default, a wq guarantees non-reentrance only on the same - CPU. A work item may not be executed concurrently on the same - CPU by multiple workers but is allowed to be executed - concurrently on multiple CPUs. This flag makes sure - non-reentrance is enforced across all CPUs. Work items queued - to a non-reentrant wq are guaranteed to be executed by at most - one worker system-wide at any given time. - - WQ_UNBOUND - - Work items queued to an unbound wq are served by a special - gcwq which hosts workers which are not bound to any specific - CPU. This makes the wq behave as a simple execution context - provider without concurrency management. The unbound gcwq - tries to start execution of work items as soon as possible. - Unbound wq sacrifices locality but is useful for the following - cases. - - * Wide fluctuation in the concurrency level requirement is - expected and using bound wq may end up creating large number - of mostly unused workers across different CPUs as the issuer - hops through different CPUs. - - * Long running CPU intensive workloads which can be better - managed by the system scheduler. - - WQ_FREEZEABLE - - A freezeable wq participates in the freeze phase of the system - suspend operations. Work items on the wq are drained and no - new work item starts execution until thawed. - - WQ_RESCUER - - All wq which might be used in the memory reclaim paths _MUST_ - have this flag set. This reserves one worker exclusively for - the execution of this wq under memory pressure. - - WQ_HIGHPRI - - Work items of a highpri wq are queued at the head of the - worklist of the target gcwq and start execution regardless of - the current concurrency level. In other words, highpri work - items will always start execution as soon as execution - resource is available. - - Ordering among highpri work items is preserved - a highpri - work item queued after another highpri work item will start - execution after the earlier highpri work item starts. - - Although highpri work items are not held back by other - runnable work items, they still contribute to the concurrency - level. Highpri work items in runnable state will prevent - non-highpri work items from starting execution. - - This flag is meaningless for unbound wq. - - WQ_CPU_INTENSIVE - - Work items of a CPU intensive wq do not contribute to the - concurrency level. In other words, runnable CPU intensive - work items will not prevent other work items from starting - execution. This is useful for bound work items which are - expected to hog CPU cycles so that their execution is - regulated by the system scheduler. - - Although CPU intensive work items don't contribute to the - concurrency level, start of their executions is still - regulated by the concurrency management and runnable - non-CPU-intensive work items can delay execution of CPU - intensive work items. - - This flag is meaningless for unbound wq. - - WQ_HIGHPRI | WQ_CPU_INTENSIVE - - This combination makes the wq avoid interaction with - concurrency management completely and behave as a simple - per-CPU execution context provider. Work items queued on a - highpri CPU-intensive wq start execution as soon as resources - are available and don't affect execution of other work items. - -@max_active: - -@max_active determines the maximum number of execution contexts per -CPU which can be assigned to the work items of a wq. For example, -with @max_active of 16, at most 16 work items of the wq can be -executing at the same time per CPU. - -Currently, for a bound wq, the maximum limit for @max_active is 512 -and the default value used when 0 is specified is 256. For an unbound -wq, the limit is higher of 512 and 4 * num_possible_cpus(). These -values are chosen sufficiently high such that they are not the -limiting factor while providing protection in runaway cases. - -The number of active work items of a wq is usually regulated by the -users of the wq, more specifically, by how many work items the users -may queue at the same time. Unless there is a specific need for -throttling the number of active work items, specifying '0' is -recommended. - -Some users depend on the strict execution ordering of ST wq. The -combination of @max_active of 1 and WQ_UNBOUND is used to achieve this -behavior. Work items on such wq are always queued to the unbound gcwq -and only one work item can be active at any given time thus achieving -the same ordering property as ST wq. - - -5. Example Execution Scenarios - -The following example execution scenarios try to illustrate how cmwq -behave under different configurations. - - Work items w0, w1, w2 are queued to a bound wq q0 on the same CPU. - w0 burns CPU for 5ms then sleeps for 10ms then burns CPU for 5ms - again before finishing. w1 and w2 burn CPU for 5ms then sleep for - 10ms. - -Ignoring all other tasks, works and processing overhead, and assuming -simple FIFO scheduling, the following is one highly simplified version -of possible sequences of events with the original wq. - - TIME IN MSECS EVENT - 0 w0 starts and burns CPU - 5 w0 sleeps - 15 w0 wakes up and burns CPU - 20 w0 finishes - 20 w1 starts and burns CPU - 25 w1 sleeps - 35 w1 wakes up and finishes - 35 w2 starts and burns CPU - 40 w2 sleeps - 50 w2 wakes up and finishes - -And with cmwq with @max_active >= 3, - - TIME IN MSECS EVENT - 0 w0 starts and burns CPU - 5 w0 sleeps - 5 w1 starts and burns CPU - 10 w1 sleeps - 10 w2 starts and burns CPU - 15 w2 sleeps - 15 w0 wakes up and burns CPU - 20 w0 finishes - 20 w1 wakes up and finishes - 25 w2 wakes up and finishes - -If @max_active == 2, - - TIME IN MSECS EVENT - 0 w0 starts and burns CPU - 5 w0 sleeps - 5 w1 starts and burns CPU - 10 w1 sleeps - 15 w0 wakes up and burns CPU - 20 w0 finishes - 20 w1 wakes up and finishes - 20 w2 starts and burns CPU - 25 w2 sleeps - 35 w2 wakes up and finishes - -Now, let's assume w1 and w2 are queued to a different wq q1 which has -WQ_HIGHPRI set, - - TIME IN MSECS EVENT - 0 w1 and w2 start and burn CPU - 5 w1 sleeps - 10 w2 sleeps - 10 w0 starts and burns CPU - 15 w0 sleeps - 15 w1 wakes up and finishes - 20 w2 wakes up and finishes - 25 w0 wakes up and burns CPU - 30 w0 finishes - -If q1 has WQ_CPU_INTENSIVE set, - - TIME IN MSECS EVENT - 0 w0 starts and burns CPU - 5 w0 sleeps - 5 w1 and w2 start and burn CPU - 10 w1 sleeps - 15 w2 sleeps - 15 w0 wakes up and burns CPU - 20 w0 finishes - 20 w1 wakes up and finishes - 25 w2 wakes up and finishes - - -6. Guidelines - -* Do not forget to use WQ_RESCUER if a wq may process work items which - are used during memory reclaim. Each wq with WQ_RESCUER set has one - rescuer thread reserved for it. If there is dependency among - multiple work items used during memory reclaim, they should be - queued to separate wq each with WQ_RESCUER. - -* Unless strict ordering is required, there is no need to use ST wq. - -* Unless there is a specific need, using 0 for @max_active is - recommended. In most use cases, concurrency level usually stays - well under the default limit. - -* A wq serves as a domain for forward progress guarantee (WQ_RESCUER), - flush and work item attributes. Work items which are not involved - in memory reclaim and don't need to be flushed as a part of a group - of work items, and don't require any special attribute, can use one - of the system wq. There is no difference in execution - characteristics between using a dedicated wq and a system wq. - -* Unless work items are expected to consume a huge amount of CPU - cycles, using a bound wq is usually beneficial due to the increased - level of locality in wq operations and work item execution. diff --git a/trunk/MAINTAINERS b/trunk/MAINTAINERS index df342839b8c1..e7c528ff1013 100644 --- a/trunk/MAINTAINERS +++ b/trunk/MAINTAINERS @@ -1135,7 +1135,7 @@ ATLX ETHERNET DRIVERS M: Jay Cliburn M: Chris Snook M: Jie Yang -L: netdev@vger.kernel.org +L: atl1-devel@lists.sourceforge.net W: http://sourceforge.net/projects/atl1 W: http://atl1.sourceforge.net S: Maintained @@ -1220,7 +1220,7 @@ F: drivers/auxdisplay/ F: include/linux/cfag12864b.h AVR32 ARCHITECTURE -M: Hans-Christian Egtvedt +M: Haavard Skinnemoen W: http://www.atmel.com/products/AVR32/ W: http://avr32linux.org/ W: http://avrfreaks.net/ @@ -1228,7 +1228,7 @@ S: Supported F: arch/avr32/ AVR32/AT32AP MACHINE SUPPORT -M: Hans-Christian Egtvedt +M: Haavard Skinnemoen S: Supported F: arch/avr32/mach-at32ap/ @@ -2199,12 +2199,6 @@ W: http://acpi4asus.sf.net S: Maintained F: drivers/platform/x86/eeepc-laptop.c -EFIFB FRAMEBUFFER DRIVER -L: linux-fbdev@vger.kernel.org -M: Peter Jones -S: Maintained -F: drivers/video/efifb.c - EFS FILESYSTEM W: http://aeschi.ch.eu.org/efs/ S: Orphan @@ -2663,12 +2657,9 @@ S: Maintained F: drivers/media/video/gspca/ HARDWARE MONITORING -M: Jean Delvare -M: Guenter Roeck L: lm-sensors@lm-sensors.org W: http://www.lm-sensors.org/ -T: quilt kernel.org/pub/linux/kernel/people/jdelvare/linux-2.6/jdelvare-hwmon/ -S: Maintained +S: Orphan F: Documentation/hwmon/ F: drivers/hwmon/ F: include/linux/hwmon*.h @@ -3905,8 +3896,10 @@ F: Documentation/serial/moxa-smartio F: drivers/char/mxser.* MSI LAPTOP SUPPORT -M: Lee, Chun-Yi +M: Lennart Poettering L: platform-driver-x86@vger.kernel.org +W: https://tango.0pointer.de/mailman/listinfo/s270-linux +W: http://0pointer.de/lennart/tchibo.html S: Maintained F: drivers/platform/x86/msi-laptop.c @@ -3946,7 +3939,7 @@ F: drivers/char/isicom.c F: include/linux/isicom.h MUSB MULTIPOINT HIGH SPEED DUAL-ROLE CONTROLLER -M: Felipe Balbi +M: Felipe Balbi L: linux-usb@vger.kernel.org T: git git://gitorious.org/usb/usb.git S: Maintained @@ -4244,7 +4237,7 @@ S: Maintained F: drivers/char/hw_random/omap-rng.c OMAP USB SUPPORT -M: Felipe Balbi +M: Felipe Balbi M: David Brownell L: linux-usb@vger.kernel.org L: linux-omap@vger.kernel.org diff --git a/trunk/Makefile b/trunk/Makefile index 3133a5772eeb..92ab33f16cf0 100644 --- a/trunk/Makefile +++ b/trunk/Makefile @@ -1,7 +1,7 @@ VERSION = 2 PATCHLEVEL = 6 SUBLEVEL = 36 -EXTRAVERSION = -rc5 +EXTRAVERSION = -rc4 NAME = Sheep on Meth # *DOCUMENTATION* diff --git a/trunk/arch/Kconfig b/trunk/arch/Kconfig index fe48fc7a3eba..4877a8c8ee16 100644 --- a/trunk/arch/Kconfig +++ b/trunk/arch/Kconfig @@ -32,9 +32,8 @@ config HAVE_OPROFILE config KPROBES bool "Kprobes" - depends on MODULES + depends on KALLSYMS && MODULES depends on HAVE_KPROBES - select KALLSYMS help Kprobes allows you to trap at almost any kernel address and execute a callback function. register_kprobe() establishes @@ -46,6 +45,7 @@ config OPTPROBES def_bool y depends on KPROBES && HAVE_OPTPROBES depends on !PREEMPT + select KALLSYMS_ALL config HAVE_EFFICIENT_UNALIGNED_ACCESS bool diff --git a/trunk/arch/alpha/include/asm/cacheflush.h b/trunk/arch/alpha/include/asm/cacheflush.h index 012f1243b1c1..01d71e1c8a9e 100644 --- a/trunk/arch/alpha/include/asm/cacheflush.h +++ b/trunk/arch/alpha/include/asm/cacheflush.h @@ -43,8 +43,6 @@ extern void smp_imb(void); /* ???
