sched: Use initial_task_util load for new tasks
Currently, we are exposing the initial_task_util tunable but not honoring it. Fix it by using the tunable for initial load to newly created tasks. Since this tunable is used in end user builds, move the tunable out of SCHED_DEBUG.

ANDROID: sched/fair: Add eas (& cas) specific rq, sd and task stats
The statistic counter are placed in the eas (& cas) wakeup path. Each
of them has one representation for the runqueue (rq), the sched_domain
(sd) and the task.
A task counter is always incremented. A rq counter is always
incremented for the rq the scheduler is currently running on. A sd
counter is only incremented if a relation to a sd exists.
The counters are exposed:
(1) In /proc/schedstat for rq's and sd's:
$ cat /proc/schedstat
...
cpu0 71422 0 2321254 ...
eas 44144 0 0 19446 0 24698 568435 51621 156932 133 222011 17459 120279 516814 83 0 156962 359235 176439 139981
<- runqueue for cpu0
...
domain0 3 42430 42331 ...
eas 0 0 0 14200 0 0 0 0 0 0 0 0 0 0 0 0 0 0 66355 0 <- MC sched domain for cpu0
...
The per-cpu eas vector has the following elements:
sis_attempts sis_idle sis_cache_affine sis_suff_cap sis_idle_cpu sis_count ||
secb_attempts secb_sync secb_idle_bt secb_insuff_cap secb_no_nrg_sav secb_nrg_sav secb_count ||
fbt_attempts fbt_no_cpu fbt_no_sd fbt_pref_idle fbt_count ||
cas_attempts cas_count
The following relations exist between these counters (from cpu0 eas
vector above):
sis_attempts = sis_idle + sis_cache_affine + sis_suff_cap + sis_idle_cpu + sis_count
44144 = 0 + 0 + 19446 + 0 + 24698
secb_attempts = secb_sync + secb_idle_bt + secb_insuff_cap + secb_no_nrg_sav + secb_nrg_sav + secb_count
568435 = 51621 + 156932 + 133 + 222011 + 17459 + 120279
fbt_attempts = fbt_no_cpu + fbt_no_sd + fbt_pref_idle + fbt_count + (return -1)
516814 = 83 + 0 + 156962 + 359235 + (534)
cas_attempts = cas_count + (return -1 or smp_processor_id())
176439 = 139981 + (36458)
(2) In /proc/$PROCESS_PID/task/$TASK_PID/sched for a task.
example: main thread of system_server
$ cat /proc/1083/task/1083/sched
...
se.statistics.nr_wakeups_sis_attempts : 945
se.statistics.nr_wakeups_sis_idle : 0
se.statistics.nr_wakeups_sis_cache_affine : 0
se.statistics.nr_wakeups_sis_suff_cap : 219
se.statistics.nr_wakeups_sis_idle_cpu : 0
se.statistics.nr_wakeups_sis_count : 726
se.statistics.nr_wakeups_secb_attempts : 10376
se.statistics.nr_wakeups_secb_sync : 1462
se.statistics.nr_wakeups_secb_idle_bt : 6984
se.statistics.nr_wakeups_secb_insuff_cap : 3
se.statistics.nr_wakeups_secb_no_nrg_sav : 927
se.statistics.nr_wakeups_secb_nrg_sav : 206
se.statistics.nr_wakeups_secb_count : 794
se.statistics.nr_wakeups_fbt_attempts : 8914
se.statistics.nr_wakeups_fbt_no_cpu : 0
se.statistics.nr_wakeups_fbt_no_sd : 0
se.statistics.nr_wakeups_fbt_pref_idle : 6987
se.statistics.nr_wakeups_fbt_count : 1554
se.statistics.nr_wakeups_cas_attempts : 3107
se.statistics.nr_wakeups_cas_count : 1195
...
The same relation between the counters as in the per-cpu case apply.

sched: remove "hmp" references in the code
HMP specific code is removed in the previous patches. There are still references to HMP in the code that is shared with WALT. Rename hmp_stats and hmp_flags methods in rq structure to walt_stats and walt_flags. Change-Id: I37f7ef1893e479de0e8a2c3b809a7e2e631adead Signed-off-by: Pavankumar Kondeti <pkondeti@codeaurora.org> |

sched: remove the unused HMP specific code
Remove the unused HMP specific code, mostly wrappers used in load balancer and task placement. The CFS_BANDWIDTH feature is supported for HMP but not for WALT. So remove any remaining references to this feature. It will be reintroduced for WALT in the subsequent patches.

sched/walt: factor out WALT from HMP scheduler
At present, hmp.c contains HMP task placement logic as well as WALT. Factor out WALT logic into a separate file walt.c so EAS can use WALT as CPU load tracking and frequency guidance algorithm. Also set sched_io_is_busy = 1 by default. Change-Id: I96c3fd7d637b9bfa283083a1a6ff6d5dd261e0fb Signed-off-by: Joonwoo Park <joonwoop@codeaurora.org> |

sched: Add the mechanics of top task tracking for frequency guidance
The previous patches in this rewrite of scheduler guided frequency selection reintroduces the part-picture problem that we addressed in our initial implementation. In that, when tasks migrate across CPUs within a cluster, we end up losing the complete picture of the sequential nature of the workload. This patch aims to solve that problem slightly differently. We track the top task on every CPU within a window. Top task is defined as the task that runs the most in a given window. This enhances our ability to detect the sequential nature of workloads. A single migrating task executing for an entire window will cause 100% load to be reported for frequency guidance instead of the maximum footprint left on any individual CPU in the task's trail. There are cases, that this new approach does not address. Namely, cases where the sum of two or more tasks accurately reflects the true sequential nature of the workload. Future optimizations might aim to tackle that problem. To track top tasks, we first realize that there is no strict need to maintain the task struct itself as long as we know the load exerted by the top task. We also realize that to maintain top tasks on every CPU we have to track the execution of every single task that runs during the window. The load associated with a task needs to be migrated when the task migrates from one CPU to another. When the top task migrates away, we need to locate the second top task and so on. Given the above realizations, we use hashmaps to track top task load both for the current and the previous window. This hashmap is implemented as an array of fixed size. The key of the hashmap is given by task_execution_time_in_a_window / array_size. The size of the array (number of buckets in the hashmap) dictate the load granularity of each bucket. The value stored in each bucket is a refcount of all the tasks that executed long enough to be in that bucket. This approach has a few benefits. Firstly, any top task stats update now take O(1) time. While task migration is also O(1), it does still involve going through up to the size of the array to find the second top task. Further patches will aim to optimize this behavior. Secondly, and more importantly, not having to store the task struct itself saves a lot of memory usage in that 1) there is no need to retrieve task structs later causing cache misses and 2) we don't have to unnecessarily hold up task memory for up to 2 full windows by calling get_task_struct() after a task exits.

ANDROID: sched/debug: Add energy procfs interface
This patch makes the energy data available via procfs. The related files are placed as sub-directory named 'energy' inside the /proc/sys/kernel/sched_domain/cpuX/domainY/groupZ directory for those cpu/domain/group tuples which have energy information. The following example depicts the contents of /proc/sys/kernel/sched_domain/cpu0/domain0/group[01] for a system which has energy information attached to domain level 0. ├── cpu0 │ ├── domain0 │ │ ├── busy_factor │ │ ├── busy_idx │ │ ├── cache_nice_tries │ │ ├── flags │ │ ├── forkexec_idx │ │ ├── group0 │ │ │ └── energy │ │ │ ├── cap_states │ │ │ ├── idle_states │ │ │ ├── nr_cap_states │ │ │ └── nr_idle_states │ │ ├── group1 │ │ │ └── energy │ │ │ ├── cap_states │ │ │ ├── idle_states │ │ │ ├── nr_cap_states │ │ │ └── nr_idle_states │ │ ├── idle_idx │ │ ├── imbalance_pct │ │ ├── max_interval │ │ ├── max_newidle_lb_cost │ │ ├── min_interval │ │ ├── name │ │ ├── newidle_idx │ │ └── wake_idx │ └── domain1 │ ├── busy_factor │ ├── busy_idx │ ├── cache_nice_tries │ ├── flags │ ├── forkexec_idx │ ├── idle_idx │ ├── imbalance_pct │ ├── max_interval │ ├── max_newidle_lb_cost │ ├── min_interval │ ├── name │ ├── newidle_idx │ └── wake_idx The files 'nr_idle_states' and 'nr_cap_states' contain a scalar value whereas 'idle_states' and 'cap_states' contain a vector of power consumption at this idle state respectively (compute capacity, power consumption) at this capacity state.

sched: Introduce HMP scheduling
Add a snapshot of all changes associated with the HMP scheduler ported over to the latest kernel version. This will allow proper big Little scheduling for targets that will use this kernel version. The msm-4-4 snapshot is taken at commitcc60f0790f27 (sched: constrain HMP scheduler tunable range with in better way). Please note that this is not an exact snapshot; certain HMP related code has been removed. This includes redundant code, useless CONFIG options, rarely taken error code paths, runtime enable/disable support for the HMP scheduler.

sched/debug: Rename 'schedstat_val()' -> 'schedstat_val_or_zero()'
The schedstat_val() macro's behavior is kind of surprising: when schedstat is runtime disabled, it returns zero. Rename it to schedstat_val_or_zero(). There's also a need for a similar macro which doesn't have the 'if (schedstat_enable())' check, to avoid doing the check twice. Create a new 'schedstat_val()' macro for that.

sched/debug: Clean up schedstat macros
The schedstat_*() macros are inconsistent: most of them take a pointer and a field which the macro combines, whereas schedstat_set() takes the already combined ptr->field. The already combined ptr->field argument is actually more intuitive and easier to use, and there's no reason to require the user to split the variable up, so convert the macros to use the combined argument.

cgroup: make cgroup_path() and friends behave in the style of strlcpy()
cgroup_path() and friends used to format the path from the end and thus the resulting path usually didn't start at the start of the passed in buffer. Also, when the buffer was too small, the partial result was truncated from the head rather than tail and there was no way to tell how long the full path would be. These make the functions less robust and more awkward to use. With recent updates to kernfs_path(), cgroup_path() and friends can be made to behave in strlcpy() style. * cgroup_path(), cgroup_path_ns[_locked]() and task_cgroup_path() now always return the length of the full path. If buffer is too small, it contains nul terminated truncated output. * All users updated accordingly. v2: cgroup_path() usage in kernel/sched/debug.c converted.

sched/debug: Add deadline scheduler bandwidth ratio to /proc/sched_debug
Playing with SCHED_DEADLINE and cpusets, I found that I was unable to create
new SCHED_DEADLINE tasks, with the error of EBUSY as if the bandwidth was
already used up. I then realized there wa no way to see what bandwidth is
used by the runqueues to debug the issue.
By adding the dl_bw->bw and dl_bw->total_bw to the output of the deadline
info in /proc/sched_debug, this allows us to see what bandwidth has been
reserved and where a problem may exist.
For example, before the issue we see the ratio of the bandwidth:
# cat /proc/sys/kernel/sched_rt_runtime_us
950000
# cat /proc/sys/kernel/sched_rt_period_us
1000000
# grep dl /proc/sched_debug
dl_rq[0]:
.dl_nr_running : 0
.dl_bw->bw : 996147
.dl_bw->total_bw : 0

.dl_nr_running : 0
.dl_bw->bw : 996147
.dl_bw->total_bw : 0

.dl_bw->total_bw : 0
dl_rq[4]:

.dl_bw->total_bw : 0
dl_rq[5]:
.dl_nr_running : 0
.dl_bw->bw : 996147
.dl_bw->total_bw : 0
dl_rq[6]:
.dl_nr_running : 0
.dl_bw->bw : 996147
.dl_bw->total_bw : 0
dl_rq[7]:
.dl_nr_running : 0
.dl_bw->bw : 996147
.dl_bw->total_bw : 0
Note: (950000 / 1000000) << 20 == 996147
After I played with cpusets and hit the issue, the result is now:
# grep dl /proc/sched_debug
dl_rq[0]:
.dl_nr_running : 0
.dl_bw->bw : 996147
.dl_bw->total_bw : -104857
dl_rq[1]:
.dl_nr_running : 0
.dl_bw->bw : 996147
.dl_bw->total_bw : 104857
dl_rq[2]:
.dl_nr_running : 0
.dl_bw->bw : 996147
.dl_bw->total_bw : 104857
dl_rq[3]:
.dl_nr_running : 0
.dl_bw->bw : 996147
.dl_bw->total_bw : 104857
dl_rq[4]:
.dl_nr_running : 0
.dl_bw->bw : 996147
.dl_bw->total_bw : -104857
dl_rq[5]:

.dl_bw->bw : 996147
.dl_bw->total_bw : -104857
dl_rq[6]:
.dl_nr_running : 0
.dl_bw->bw : 996147
.dl_bw->total_bw : -104857
dl_rq[7]:
.dl_nr_running : 0
.dl_bw->bw : 996147
.dl_bw->total_bw : -104857
This shows that there is definitely a problem as we should never have a
negative total bandwidth.

sched/debug: Make schedstats a runtime tunable that is disabled by default
schedstats is very useful during debugging and performance tuning but it
incurs overhead to calculate the stats. As such, even though it can be
disabled at build time, it is often enabled as the information is useful.
This patch adds a kernel command-line and sysctl tunable to enable or
disable schedstats on demand (when it's built in). It is disabled
by default as someone who knows they need it can also learn to enable
it when necessary.
The benefits are dependent on how scheduler-intensive the workload is.
If it is then the patch reduces the number of cycles spent calculating
the stats with a small benefit from reducing the cache footprint of the
scheduler.
These measurements were taken from a 48-core 2-socket
machine with Xeon(R) E5-2670 v3 cpus although they were also tested on a
single socket machine 8-core machine with Intel i7-3770 processors.

Small improvement and similar gains were seen on the UMA machine.
The gain is small but it stands to reason that doing less work in the
scheduler is a good thing. The downside is that the lack of schedstats and
tracepoints may be surprising to experts doing performance analysis until
they find the existence of the schedstats= parameter or schedstats sysctl.
It will be automatically activated for latencytop and sleep profiling to
alleviate the problem. For tracepoints, there is a simple warning as it's
not safe to activate schedstats in the context when it's known the tracepoint
may be wanted but is unavailable.

sched/fair: Provide runnable_load_avg back to cfs_rq
The cfs_rq's load_avg is composed of runnable_load_avg and blocked_load_avg. Before this series, sometimes the runnable_load_avg is used, and sometimes the load_avg is used. Completely replacing all uses of runnable_load_avg with load_avg may be too big a leap, i.e., the blocked_load_avg is concerned to result in overrated load. Therefore, we get runnable_load_avg back. The new cfs_rq's runnable_load_avg is improved to be updated with all of the runnable sched_eneities at the same time, so the one sched_entity updated and the others stale problem is solved.

sched/fair: Rewrite runnable load and utilization average tracking
The idea of runnable load average (let runnable time contribute to weight)
was proposed by Paul Turner and Ben Segall, and it is still followed by
this rewrite. This rewrite aims to solve the following issues:
1. cfs_rq's load average (namely runnable_load_avg and blocked_load_avg) is
updated at the granularity of an entity at a time, which results in the
cfs_rq's load average is stale or partially updated: at any time, only
one entity is up to date, all other entities are effectively lagging
behind. This is undesirable.
To illustrate, if we have n runnable entities in the cfs_rq, as time
elapses, they certainly become outdated:
t0: cfs_rq { e1_old, e2_old, ..., en_old }
and when we update:
t1: update e1, then we have cfs_rq { e1_new, e2_old, ..., en_old }
t2: update e2, then we have cfs_rq { e1_old, e2_new, ..., en_old }
...
We solve this by combining all runnable entities' load averages together
in cfs_rq's avg, and update the cfs_rq's avg as a whole. This is based
on the fact that if we regard the update as a function, then:
w * update(e) = update(w * e) and
update(e1) + update(e2) = update(e1 + e2), then
w1 * update(e1) + w2 * update(e2) = update(w1 * e1 + w2 * e2)
therefore, by this rewrite, we have an entirely updated cfs_rq at the
time we update it:
t1: update cfs_rq { e1_new, e2_new, ..., en_new }
t2: update cfs_rq { e1_new, e2_new, ..., en_new }
...
2. cfs_rq's load average is different between top rq->cfs_rq and other
task_group's per CPU cfs_rqs in whether or not blocked_load_average
contributes to the load.
The basic idea behind runnable load average (the same for utilization)
is that the blocked state is taken into account as opposed to only
accounting for the currently runnable state. Therefore, the average
should include both the runnable/running and blocked load averages.
This rewrite does that.
In addition, we also combine runnable/running and blocked averages
of all entities into the cfs_rq's average, and update it together at
once. This is based on the fact that:
update(runnable) + update(blocked) = update(runnable + blocked)
This significantly reduces the code as we don't need to separately
maintain/update runnable/running load and blocked load.
3. How task_group entities' share is calculated is complex and imprecise.
We reduce the complexity in this rewrite to allow a very simple rule:
the task_group's load_avg is aggregated from its per CPU cfs_rqs's
load_avgs. Then group entity's weight is simply proportional to its
own cfs_rq's load_avg / task_group's load_avg. To illustrate,
if a task_group has { cfs_rq1, cfs_rq2, ..., cfs_rqn }, then,
task_group_avg = cfs_rq1_avg + cfs_rq2_avg + ... + cfs_rqn_avg, then
cfs_rqx's entity's share = cfs_rqx_avg / task_group_avg * task_group's share
To sum up, this rewrite in principle is equivalent to the current one, but
fixes the issues described above. Turns out, it significantly reduces the
code complexity and hence increases clarity and efficiency. In addition,
the new averages are more smooth/continuous (no spurious spikes and valleys)
and updated more consistently and quickly to reflect the load dynamics.
As a result, we have less load tracking overhead, better performance,
and especially better power efficiency due to more balanced load.

This version differs from the original one in the sense that it's not linked to task_group. The rq's utilization_load_avg will be used to check if a rq is overloaded or not instead of trying to compute how many tasks a group of CPUs can handle.

This patch simplifies task_struct by removing the four numa_* pointers in the same array and replacing them with the array pointer. By doing this, on x86_64, the size of task_struct is reduced by 3 ulong pointers (24 bytes on x86_64). A new parameter is added to the task_faults_idx function so that it can return an index to the correct offset, corresponding with the old precalculated pointers. All of the code in sched/ that depended on task_faults_idx and numa_* was changed in order to match the new logic.

Merge branch 'for-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup updates from Tejun Heo:
"A lot updates for cgroup:
- The biggest one is cgroup's conversion to kernfs. cgroup took
after the long abandoned vfs-entangled sysfs implementation and
made it even more convoluted over time. cgroup's internal objects
were fused with vfs objects which also brought in vfs locking and
object lifetime rules. Naturally, there are places where vfs rules
don't fit and nasty hacks, such as credential switching or lock
dance interleaving inode mutex and cgroup_mutex with object serial
number comparison thrown in to decide whether the operation is
actually necessary, needed to be employed.
After conversion to kernfs, internal object lifetime and locking
rules are mostly isolated from vfs interactions allowing shedding
of several nasty hacks and overall simplification. This will also
allow implmentation of operations which may affect multiple cgroups
which weren't possible before as it would have required nesting
i_mutexes.
- Various simplifications including dropping of module support,
easier cgroup name/path handling, simplified cgroup file type
handling and task_cg_lists optimization.
- Prepatory changes for the planned unified hierarchy, which is still
a patchset away from being actually operational. The dummy
hierarchy is updated to serve as the default unified hierarchy.
Controllers which aren't claimed by other hierarchies are
associated with it, which BTW was what the dummy hierarchy was for
anyway.
- Various fixes from Li and others. This pull request includes some
patches to add missing slab.h to various subsystems. This was
triggered xattr.h include removal from cgroup.h. cgroup.h
indirectly got included a lot of files which brought in xattr.h
which brought in slab.h.
There are several merge commits - one to pull in kernfs updates
necessary for converting cgroup (already in upstream through
driver-core), others for interfering changes in the fixes branch"

cgroup: remove cgroup->name
cgroup->name handling became quite complicated over time involving
dedicated struct cgroup_name for RCU protection. Now that cgroup is
on kernfs, we can drop all of it and simply use kernfs_name/path() and
friends. Replace cgroup->name and all related code with kernfs
name/path constructs.
* Reimplement cgroup_name() and cgroup_path() as thin wrappers on top
of kernfs counterparts, which involves semantic changes.
pr_cont_cgroup_name() and pr_cont_cgroup_path() added.
* cgroup->name handling dropped from cgroup_rename().
* All users of cgroup_name/path() updated to the new semantics. Users
which were formatting the string just to printk them are converted
to use pr_cont_cgroup_name/path() instead, which simplifies things
quite a bit. As cgroup_name() no longer requires RCU read lock
around it, RCU lockings which were protecting only cgroup_name() are
removed.
v2: Comment above oom_info_lock updated as suggested by Michal.
v3: dummy_top doesn't have a kn associated and
pr_cont_cgroup_name/path() ended up calling the matching kernfs
functions with NULL kn leading to oops. Test for NULL kn and
print "/" if so. This issue was reported by Fengguang Wu.

sched/numa: Rename p->numa_faults to numa_faults_memory
In order to get a more consistent naming scheme, making it clear which fault statistics track memory locality, and which track CPU locality, rename the memory fault statistics.

sched/clock, x86: Use a static_key for sched_clock_stable
In order to avoid the runtime condition and variable load turn
sched_clock_stable into a static_key.
Also provide a shorter implementation of local_clock() and
cpu_clock(int) when sched_clock_stable==1.

sched: Avoid throttle_cfs_rq() racing with period_timer stopping
throttle_cfs_rq() doesn't check to make sure that period_timer is running, and while update_curr/assign_cfs_runtime does, a concurrently running period_timer on another cpu could cancel itself between this cpu's update_curr and throttle_cfs_rq(). If there are no other cfs_rqs running in the tg to restart the timer, this causes the cfs_rq to be stranded forever. Fix this by calling __start_cfs_bandwidth() in throttle if the timer is inactive. (Also add some sched_debug lines for cfs_bandwidth.) Tested: make a run/sleep task in a cgroup, loop switching the cgroup between 1ms/100ms quota and unlimited, checking for timer_active=0 and throttled=1 as a failure. With the throttle_cfs_rq() change commented out this fails, with the full patch it passes.
