There's probably no need to -+read it unless you plan to develop a userspace helper. -+ -+The fbcondecor protocol -+----------------------- -+ -+The fbcondecor protocol defines a communication interface between the kernel and -+the userspace fbcondecor helper. -+ -+The kernel side is responsible for: -+ -+ * rendering console text, using an image as a background (instead of a -+ standard solid color fbcon uses), -+ * accepting commands from the user via ioctls on the fbcondecor device, -+ * calling the userspace helper to set things up as soon as the fb subsystem -+ is initialized. -+ -+The userspace helper is responsible for everything else, including parsing -+configuration files, decompressing the image files whenever the kernel needs -+it, and communicating with the kernel if necessary. -+ -+The fbcondecor protocol specifies how communication is done in both ways: -+kernel->userspace and userspace->helper. -+ -+Kernel -> Userspace -+------------------- -+ -+The kernel communicates with the userspace helper by calling it and specifying -+the task to be done in a series of arguments. -+ -+The arguments follow the pattern: -+<fbcondecor protocol version> <command> <parameters> -+ -+All commands defined in fbcondecor protocol v2 have the following parameters: -+ virtual console -+ framebuffer number -+ theme -+ -+Fbcondecor protocol v1 specified an additional 'fbcondecor mode' after the -+framebuffer number. Fbcondecor protocol v1 is deprecated and should not be used. -+ -+Fbcondecor protocol v2 specifies the following commands: -+ -+getpic -+------ -+ The kernel issues this command to request image data. It's up to the -+ userspace helper to find a background image appropriate for the specified -+ theme and the current resolution. The userspace helper should respond by -+ issuing the FBIOCONDECOR_SETPIC ioctl. -+ -+init -+---- -+ The kernel issues this command after the fbcondecor device is created and -+ the fbcondecor interface is initialized. Upon receiving 'init', the userspace -+ helper should parse the kernel command line (/proc/cmdline) or otherwise -+ decide whether fbcondecor is to be activated. -+ -+ To activate fbcondecor on the first console the helper should issue the -+ FBIOCONDECOR_SETCFG, FBIOCONDECOR_SETPIC and FBIOCONDECOR_SETSTATE commands, -+ in the above-mentioned order. -+ -+ When the userspace helper is called in an early phase of the boot process -+ (right after the initialization of fbcon), no filesystems will be mounted. -+ The helper program should mount sysfs and then create the appropriate -+ framebuffer, fbcondecor and tty0 devices (if they don't already exist) to get -+ current display settings and to be able to communicate with the kernel side. -+ It should probably also mount the procfs to be able to parse the kernel -+ command line parameters. -+ -+ Note that the console sem is not held when the kernel calls fbcondecor_helper -+ with the 'init' command. The fbcondecor helper should perform all ioctls with -+ origin set to FBCON_DECOR_IO_ORIG_USER. -+ -+modechange -+---------- -+ The kernel issues this command on a mode change. The helper's response should -+ be similar to the response to the 'init' command. Note that this time the -+ console sem is held and all ioctls must be performed with origin set to -+ FBCON_DECOR_IO_ORIG_KERNEL. -+ -+ -+Userspace -> Kernel -+------------------- -+ -+Userspace programs can communicate with fbcondecor via ioctls on the -+fbcondecor device. These ioctls are to be used by both the userspace helper -+(called only by the kernel) and userspace configuration tools (run by the users). -+ -+The fbcondecor helper should set the origin field to FBCON_DECOR_IO_ORIG_KERNEL -+when doing the appropriate ioctls. All userspace configuration tools should -+use FBCON_DECOR_IO_ORIG_USER. Failure to set the appropriate value in the origin -+field when performing ioctls from the kernel helper will most likely result -+in a console deadlock. -+ -+FBCON_DECOR_IO_ORIG_KERNEL instructs fbcondecor not to try to acquire the console -+semaphore. Not surprisingly, FBCON_DECOR_IO_ORIG_USER instructs it to acquire -+the console sem. -+ -+The framebuffer console decoration provides the following ioctls (all defined in -+linux/fb.h): -+ -+FBIOCONDECOR_SETPIC -+description: loads a background picture for a virtual console -+argument: struct fbcon_decor_iowrapper*; data: struct fb_image* -+notes: -+If called for consoles other than the current foreground one, the picture data -+will be ignored. -+ -+If the current virtual console is running in a 8-bpp mode, the cmap substruct -+of fb_image has to be filled appropriately: start should be set to 16 (first -+16 colors are reserved for fbcon), len to a value <= 240 and red, green and -+blue should point to valid cmap data. The transp field is ingored. The fields -+dx, dy, bg_color, fg_color in fb_image are ignored as well. -+ -+FBIOCONDECOR_SETCFG -+description: sets the fbcondecor config for a virtual console -+argument: struct fbcon_decor_iowrapper*; data: struct vc_decor* -+notes: The structure has to be filled with valid data. -+ -+FBIOCONDECOR_GETCFG -+description: gets the fbcondecor config for a virtual console -+argument: struct fbcon_decor_iowrapper*; data: struct vc_decor* -+ -+FBIOCONDECOR_SETSTATE -+description: sets the fbcondecor state for a virtual console -+argument: struct fbcon_decor_iowrapper*; data: unsigned int* -+ values: 0 = disabled, 1 = enabled. -+ -+FBIOCONDECOR_GETSTATE -+description: gets the fbcondecor state for a virtual console -+argument: struct fbcon_decor_iowrapper*; data: unsigned int* -+ values: as in FBIOCONDECOR_SETSTATE -+ -+Info on used structures: -+ -+Definition of struct vc_decor can be found in linux/console_decor.h.

Each component -+shall be described in order to understand the significance of, and reasoning for -+it. The codebase when the first stable version was released was approximately -+9000 lines less code than the existing mainline linux kernel scheduler (in -+2.6.31). This does not even take into account the removal of documentation and -+the cgroups code that is not used. -+ -+Design reasoning. -+ -+The single runqueue refers to the queued but not running processes for the -+entire system, regardless of the number of CPUs. The reason for going back to -+a single runqueue design is that once multiple runqueues are introduced, -+per-CPU or otherwise, there will be complex interactions as each runqueue will -+be responsible for the scheduling latency and fairness of the tasks only on its -+own runqueue, and to achieve fairness and low latency across multiple CPUs, any -+advantage in throughput of having CPU local tasks causes other disadvantages. -+This is due to requiring a very complex balancing system to at best achieve some -+semblance of fairness across CPUs and can only maintain relatively low latency -+for tasks bound to the same CPUs, not across them. To increase said fairness -+and latency across CPUs, the advantage of local runqueue locking, which makes -+for better scalability, is lost due to having to grab multiple locks. -+ -+A significant feature of BFS is that all accounting is done purely based on CPU -+used and nowhere is sleep time used in any way to determine entitlement or -+interactivity. Interactivity "estimators" that use some kind of sleep/run -+algorithm are doomed to fail to detect all interactive tasks, and to falsely tag -+tasks that aren't interactive as being so. The reason for this is that it is -+close to impossible to determine that when a task is sleeping, whether it is -+doing it voluntarily, as in a userspace application waiting for input in the -+form of a mouse click or otherwise, or involuntarily, because it is waiting for -+another thread, process, I/O, kernel activity or whatever. Thus, such an -+estimator will introduce corner cases, and more heuristics will be required to -+cope with those corner cases, introducing more corner cases and failed -+interactivity detection and so on. Interactivity in BFS is built into the design -+by virtue of the fact that tasks that are waking up have not used up their quota -+of CPU time, and have earlier effective deadlines, thereby making it very likely -+they will preempt any CPU bound task of equivalent nice level. See below for -+more information on the virtual deadline mechanism. Even if they do not preempt -+a running task, because the rr interval is guaranteed to have a bound upper -+limit on how long a task will wait for, it will be scheduled within a timeframe -+that will not cause visible interface jitter. -+ -+ -+Design details. -+ -+Task insertion. -+ -+BFS inserts tasks into each relevant queue as an O(1) insertion into a double -+linked list. On insertion, *every* running queue is checked to see if the newly -+queued task can run on any idle queue, or preempt the lowest running task on the -+system. This is how the cross-CPU scheduling of BFS achieves significantly lower -+latency per extra CPU the system has. In this case the lookup is, in the worst -+case scenario, O(n) where n is the number of CPUs on the system. -+ -+Data protection. -+ -+BFS has one single lock protecting the process local data of every task in the -+global queue. Thus every insertion, removal and modification of task data in the -+global runqueue needs to grab the global lock. However, once a task is taken by -+a CPU, the CPU has its own local data copy of the running process' accounting -+information which only that CPU accesses and modifies (such as during a -+timer tick) thus allowing the accounting data to be updated lockless. Once a -+CPU has taken a task to run, it removes it from the global queue. Thus the -+global queue only ever has, at most, -+ -+ (number of tasks requesting cpu time) - (number of logical CPUs) + 1 -+ -+tasks in the global queue. This value is relevant for the time taken to look up -+tasks during scheduling. This will increase if many tasks with CPU affinity set -+in their policy to limit which CPUs they're allowed to run on if they outnumber -+the number of CPUs. The +1 is because when rescheduling a task, the CPU's -+currently running task is put back on the queue. Lookup will be described after -+the virtual deadline mechanism is explained. -+ -+Virtual deadline. -+ -+The key to achieving low latency, scheduling fairness, and "nice level" -+distribution in BFS is entirely in the virtual deadline mechanism. The one -+tunable in BFS is the rr_interval, or "round robin interval". This is the -+maximum time two SCHED_OTHER (or SCHED_NORMAL, the common scheduling policy) -+tasks of the same nice level will be running for, or looking at it the other -+way around, the longest duration two tasks of the same nice level will be -+delayed for. When a task requests cpu time, it is given a quota (time_slice) -+equal to the rr_interval and a virtual deadline. The virtual deadline is -+offset from the current time in jiffies by this equation: -+ -+ jiffies + (prio_ratio * rr_interval) -+ -+The prio_ratio is determined as a ratio compared to the baseline of nice -20 -+and increases by 10% per nice level. The deadline is a virtual one only in that -+no guarantee is placed that a task will actually be scheduled by this time, but -+it is used to compare which task should go next. There are three components to -+how a task is next chosen. First is time_slice expiration. If a task runs out -+of its time_slice, it is descheduled, the time_slice is refilled, and the -+deadline reset to that formula above. Second is sleep, where a task no longer -+is requesting CPU for whatever reason. The time_slice and deadline are _not_ -+adjusted in this case and are just carried over for when the task is next -+scheduled. Third is preemption, and that is when a newly waking task is deemed -+higher priority than a currently running task on any cpu by virtue of the fact -+that it has an earlier virtual deadline than the currently running task. The -+earlier deadline is the key to which task is next chosen for the first and -+second cases. Once a task is descheduled, it is put back on the queue, and an -+O(n) lookup of all queued-but-not-running tasks is done to determine which has -+the earliest deadline and that task is chosen to receive CPU next. -+ -+The CPU proportion of different nice tasks works out to be approximately the -+ -+ (prio_ratio difference)^2 -+ -+The reason it is squared is that a task's deadline does not change while it is -+running unless it runs out of time_slice. Thus, even if the time actually -+passes the deadline of another task that is queued, it will not get CPU time -+unless the current running task deschedules, and the time "base" (jiffies) is -+constantly moving. -+ -+Task lookup. -+ -+BFS has 103 priority queues. 100 of these are dedicated to the static priority -+of realtime tasks, and the remaining 3 are, in order of best to worst priority, -+SCHED_ISO (isochronous), SCHED_NORMAL, and SCHED_IDLEPRIO (idle priority -+scheduling). When a task of these priorities is queued, a bitmap of running -+priorities is set showing which of these priorities has tasks waiting for CPU -+time. When a CPU is made to reschedule, the lookup for the next task to get -+CPU time is performed in the following way: -+ -+First the bitmap is checked to see what static priority tasks are queued. If -+any realtime priorities are found, the corresponding queue is checked and the -+first task listed there is taken (provided CPU affinity is suitable) and lookup -+is complete. If the priority corresponds to a SCHED_ISO task, they are also -+taken in FIFO order (as they behave like SCHED_RR). If the priority corresponds -+to either SCHED_NORMAL or SCHED_IDLEPRIO, then the lookup becomes O(n). At this -+stage, every task in the runlist that corresponds to that priority is checked -+to see which has the earliest set deadline, and (provided it has suitable CPU -+affinity) it is taken off the runqueue and given the CPU. If a task has an -+expired deadline, it is taken and the rest of the lookup aborted (as they are -+chosen in FIFO order). -+ -+Thus, the lookup is O(n) in the worst case only, where n is as described -+earlier, as tasks may be chosen before the whole task list is looked over. -+ -+ -+Scalability. -+ -+The major limitations of BFS will be that of scalability, as the separate -+runqueue designs will have less lock contention as the number of CPUs rises. -+However they do not scale linearly even with separate runqueues as multiple -+runqueues will need to be locked concurrently on such designs to be able to -+achieve fair CPU balancing, to try and achieve some sort of nice-level fairness -+across CPUs, and to achieve low enough latency for tasks on a busy CPU when -+other CPUs would be more suited. BFS has the advantage that it requires no -+balancing algorithm whatsoever, as balancing occurs by proxy simply because -+all CPUs draw off the global runqueue, in priority and deadline order. Despite -+the fact that scalability is _not_ the prime concern of BFS, it both shows very -+good scalability to smaller numbers of CPUs and is likely a more scalable design -+at these numbers of CPUs. -+ -+It also has some very low overhead scalability features built into the design -+when it has been deemed their overhead is so marginal that they're worth adding. -+The first is the local copy of the running process' data to the CPU it's running -+on to allow that data to be updated lockless where possible. Then there is -+deference paid to the last CPU a task was running on, by trying that CPU first -+when looking for an idle CPU to use the next time it's scheduled. Finally there -+is the notion of cache locality beyond the last running CPU. The sched_domains -+information is used to determine the relative virtual "cache distance" that -+other CPUs have from the last CPU a task was running on. CPUs with shared -+caches, such as SMT siblings, or multicore CPUs with shared caches, are treated -+as cache local. CPUs without shared caches are treated as not cache local, and -+CPUs on different NUMA nodes are treated as very distant. This "relative cache -+distance" is used by modifying the virtual deadline value when doing lookups. -+Effectively, the deadline is unaltered between "cache local" CPUs, doubled for -+"cache distant" CPUs, and quadrupled for "very distant" CPUs. The reasoning -+behind the doubling of deadlines is as follows. The real cost of migrating a -+task from one CPU to another is entirely dependant on the cache footprint of -+the task, how cache intensive the task is, how long it's been running on that -+CPU to take up the bulk of its cache, how big the CPU cache is, how fast and -+how layered the CPU cache is, how fast a context switch is... and so on. In -+other words, it's close to random in the real world where we do more than just -+one sole workload. The only thing we can be sure of is that it's not free. So -+BFS uses the principle that an idle CPU is a wasted CPU and utilising idle CPUs -+is more important than cache locality, and cache locality only plays a part -+after that. Doubling the effective deadline is based on the premise that the -+"cache local" CPUs will tend to work on the same tasks up to double the number -+of cache local CPUs, and once the workload is beyond that amount, it is likely -+that none of the tasks are cache warm anywhere anyway. The quadrupling for NUMA -+is a value I pulled out of my arse. -+ -+When choosing an idle CPU for a waking task, the cache locality is determined -+according to where the task last ran and then idle CPUs are ranked from best -+to worst to choose the most suitable idle CPU based on cache locality, NUMA -+node locality and hyperthread sibling business. They are chosen in the -+following preference (if idle): -+ -+* Same core, idle or busy cache, idle threads -+* Other core, same cache, idle or busy cache, idle threads. -+* Same node, other CPU, idle cache, idle threads. -+* Same node, other CPU, busy cache, idle threads. -+* Same core, busy threads. -+* Other core, same cache, busy threads. -+* Same node, other CPU, busy threads. -+* Other node, other CPU, idle cache, idle threads. -+* Other node, other CPU, busy cache, idle threads. -+* Other node, other CPU, busy threads. -+ -+This shows the SMT or "hyperthread" awareness in the design as well which will -+choose a real idle core first before a logical SMT sibling which already has -+tasks on the physical CPU. -+ -+Early benchmarking of BFS suggested scalability dropped off at the 16 CPU mark. -+However this benchmarking was performed on an earlier design that was far less -+scalable than the current one so it's hard to know how scalable it is in terms -+of both CPUs (due to the global runqueue) and heavily loaded machines (due to -+O(n) lookup) at this stage. Note that in terms of scalability, the number of -+_logical_ CPUs matters, not the number of _physical_ CPUs. Thus, a dual (2x) -+quad core (4X) hyperthreaded (2X) machine is effectively a 16X. Newer benchmark -+results are very promising indeed, without needing to tweak any knobs, features -+or options. Benchmark contributions are most welcome. -+ -+ -+Features -+ -+As the initial prime target audience for BFS was the average desktop user, it -+was designed to not need tweaking, tuning or have features set to obtain benefit -+from it. Thus the number of knobs and features has been kept to an absolute -+minimum and should not require extra user input for the vast majority of cases. -+There are precisely 2 tunables, and 2 extra scheduling policies. The rr_interval -+and iso_cpu tunables, and the SCHED_ISO and SCHED_IDLEPRIO policies. In addition -+to this, BFS also uses sub-tick accounting. What BFS does _not_ now feature is -+support for CGROUPS. The average user should neither need to know what these -+are, nor should they need to be using them to have good desktop behaviour. -+ -+rr_interval -+ -+There is only one "scheduler" tunable, the round robin interval. This can be -+accessed in -+ -+ /proc/sys/kernel/rr_interval -+ -+The value is in milliseconds, and the default value is set to 6 on a -+uniprocessor machine, and automatically set to a progressively higher value on -+multiprocessor machines. The reasoning behind increasing the value on more CPUs -+is that the effective latency is decreased by virtue of there being more CPUs on -+BFS (for reasons explained above), and increasing the value allows for less -+cache contention and more throughput. Valid values are from 1 to 1000 -+Decreasing the value will decrease latencies at the cost of decreasing -+throughput, while increasing it will improve throughput, but at the cost of -+worsening latencies. The accuracy of the rr interval is limited by HZ resolution -+of the kernel configuration. Thus, the worst case latencies are usually slightly -+higher than this actual value. The default value of 6 is not an arbitrary one. -+It is based on the fact that humans can detect jitter at approximately 7ms, so -+aiming for much lower latencies is pointless under most circumstances. It is -+worth noting this fact when comparing the latency performance of BFS to other -+schedulers. Worst case latencies being higher than 7ms are far worse than -+average latencies not being in the microsecond range. -+ -+Isochronous scheduling. -+ -+Isochronous scheduling is a unique scheduling policy designed to provide -+near-real-time performance to unprivileged (ie non-root) users without the -+ability to starve the machine indefinitely. Isochronous tasks (which means -+"same time") are set using, for example, the schedtool application like so: -+ -+ schedtool -I -e amarok -+ -+This will start the audio application "amarok" as SCHED_ISO. How SCHED_ISO works -+is that it has a priority level between true realtime tasks and SCHED_NORMAL -+which would allow them to preempt all normal tasks, in a SCHED_RR fashion (ie, -+if multiple SCHED_ISO tasks are running, they purely round robin at rr_interval -+rate). However if ISO tasks run for more than a tunable finite amount of time, -+they are then demoted back to SCHED_NORMAL scheduling. This finite amount of -+time is the percentage of _total CPU_ available across the machine, configurable -+as a percentage in the following "resource handling" tunable (as opposed to a -+scheduler tunable): -+ -+ /proc/sys/kernel/iso_cpu -+ -+and is set to 70% by default. It is calculated over a rolling 5 second average -+Because it is the total CPU available, it means that on a multi CPU machine, it -+is possible to have an ISO task running as realtime scheduling indefinitely on -+just one CPU, as the other CPUs will be available. Setting this to 100 is the -+equivalent of giving all users SCHED_RR access and setting it to 0 removes the -+ability to run any pseudo-realtime tasks. -+ -+A feature of BFS is that it detects when an application tries to obtain a -+realtime policy (SCHED_RR or SCHED_FIFO) and the caller does not have the -+appropriate privileges to use those policies. When it detects this, it will -+give the task SCHED_ISO policy instead. Thus it is transparent to the user. -+Because some applications constantly set their policy as well as their nice -+level, there is potential for them to undo the override specified by the user -+on the command line of setting the policy to SCHED_ISO. To counter this, once -+a task has been set to SCHED_ISO policy, it needs superuser privileges to set -+it back to SCHED_NORMAL. This will ensure the task remains ISO and all child -+processes and threads will also inherit the ISO policy. -+ -+Idleprio scheduling. -+ -+Idleprio scheduling is a scheduling policy designed to give out CPU to a task -+_only_ when the CPU would be otherwise idle. The idea behind this is to allow -+ultra low priority tasks to be run in the background that have virtually no -+effect on the foreground tasks. This is ideally suited to distributed computing -+clients (like setiathome, folding, mprime etc) but can also be used to start -+a video encode or so on without any slowdown of other tasks. To avoid this -+policy from grabbing shared resources and holding them indefinitely, if it -+detects a state where the task is waiting on I/O, the machine is about to -+suspend to ram and so on, it will transiently schedule them as SCHED_NORMAL. As -+per the Isochronous task management, once a task has been scheduled as IDLEPRIO, -+it cannot be put back to SCHED_NORMAL without superuser privileges. Tasks can -+be set to start as SCHED_IDLEPRIO with the schedtool command like so: -+ -+ schedtool -D -e ./mprime -+ -+Subtick accounting. -+ -+It is surprisingly difficult to get accurate CPU accounting, and in many cases, -+the accounting is done by simply determining what is happening at the precise -+moment a timer tick fires off. This becomes increasingly inaccurate as the -+timer tick frequency (HZ) is lowered. It is possible to create an application -+which uses almost 100% CPU, yet by being descheduled at the right time, records -+zero CPU usage. While the main problem with this is that there are possible -+security implications, it is also difficult to determine how much CPU a task -+really does use. BFS tries to use the sub-tick accounting from the TSC clock, -+where possible, to determine real CPU usage. This is not entirely reliable, but -+is far more likely to produce accurate CPU usage data than the existing designs -+and will not show tasks as consuming no CPU usage when they actually are. Thus, -+the amount of CPU reported as being used by BFS will more accurately represent -+how much CPU the task itself is using (as is shown for example by the 'time' -+application), so the reported values may be quite different to other schedulers. -+Values reported as the 'load' are more prone to problems with this design, but -+per process values are closer to real usage. When comparing throughput of BFS -+to other designs, it is important to compare the actual completed work in terms -+of total wall clock time taken and total work done, rather than the reported -+"cpu usage". -+ -+ -+Con Kolivas <kernel@kolivas.org> Fri Aug 27 2010 -Index: linux-2.6.37-ck2/Documentation/sysctl/kernel.txt -=================================================================== ---- linux-2.6.37-ck2.orig/Documentation/sysctl/kernel.txt 2011-01-06 14:04:07.000000000 +1100 -+++ linux-2.6.37-ck2/Documentation/sysctl/kernel.txt 2011-02-14 09:47:50.984252001 +1100 -@@ -32,6 +32,7 @@ - - domainname - - hostname - - hotplug -+- iso_cpu - - java-appletviewer [ binfmt_java, obsolete ] - - java-interpreter [ binfmt_java, obsolete ] - - kstack_depth_to_print [ X86 only ] -@@ -54,6 +55,7 @@ - - randomize_va_space - - real-root-dev ==> Documentation/initrd.txt - - reboot-cmd [ SPARC only ] -+- rr_interval - - rtsig-max - - rtsig-nr - - sem -@@ -254,6 +256,16 @@ - - ============================================================== - -+iso_cpu: (BFS CPU scheduler only). -+ -+This sets the percentage cpu that the unprivileged SCHED_ISO tasks can -+run effectively at realtime priority, averaged over a rolling five -+seconds over the -whole- system, meaning all cpus. -+ -+Set to 70 (percent) by default. -+ -+============================================================== -+ - l2cr: (PPC only) - - This flag controls the L2 cache of G3 processor boards.
