ANDROID: sched: Introducing PELT multiplier
The new sysctl sched_pelt_multiplier allows a user to set a clock multiplier x2 or x4 (x1 being the default). This clock multiplier artificially speed-up PELT ramp up/down similarly to a faster half-life. Indeed, if we write PELT as a first order filter: y(t) = G * (1 - exp(t/tau)) Then we can see that multiplying the time by a constant X, is the same as dividing the time constant tau by X. y(t) = G * (1 - exp((t*X)/tau)) y(t) = G * (1 - exp(t/(tau/X))) Tau being half-life*ln(2), multiplying the PELT time is the same as dividing the half-life: - x1: 32ms half-life - x2: 16ms half-life - x4: 8ms half-life Internally, a new clock is created: rq->clock_task_mult. It sits in the clock hierarchy between rq->clock_task and rq->clock_pelt.

FROMGIT: sched/deadline: Fix reset_on_fork reporting of DL tasks
It is possible for sched_getattr() to incorrectly report the state of the reset_on_fork flag when called on a deadline task. Indeed, if the flag was set on a deadline task using sched_setattr() with flags (SCHED_FLAG_RESET_ON_FORK | SCHED_FLAG_KEEP_PARAMS), then p->sched_reset_on_fork will be set, but __setscheduler() will bail out early, which means that the dl_se->flags will not get updated by __setscheduler_params()->__setparam_dl(). Consequently, if sched_getattr() is then called on the task, __getparam_dl() will override kattr.sched_flags with the now out-of-date copy in dl_se->flags and report the stale value to userspace. To fix this, make sure to only copy the flags that are relevant to sched_deadline to and from the dl_se->flags field.

sched/uclamp: Ignore max aggregation if rq is idle
[ Upstream commit 3e1493f46390618ea78607cb30c58fc19e2a5035 ]
When a task wakes up on an idle rq, uclamp_rq_util_with() would max
aggregate with rq value. But since there is no task enqueued yet, the
values are stale based on the last task that was running. When the new
task actually wakes up and enqueued, then the rq uclamp values should
reflect that of the newly woken up task effective uclamp values.
This is a problem particularly for uclamp_max because it default to
1024. If a task p with uclamp_max = 512 wakes up, then max aggregation
would ignore the capping that should apply when this task is enqueued,
which is wrong.
Fix that by ignoring max aggregation if the rq is idle since in that
case the effective uclamp value of the rq will be the ones of the task
that will wake up.

sched/fair: Fix shift-out-of-bounds in load_balance()
[ Upstream commit 39a2a6eb5c9b66ea7c8055026303b3aa681b49a5 ]
Syzbot reported a handful of occurrences where an sd->nr_balance_failed can
grow to much higher values than one would expect.
A successful load_balance() resets it to 0; a failed one increments
it. Once it gets to sd->cache_nice_tries + 3, this *should* trigger an
active balance, which will either set it to sd->cache_nice_tries+1 or reset
it to 0. However, in case the to-be-active-balanced task is not allowed to
run on env->dst_cpu, then the increment is done without any further
modification.
This could then be repeated ad nauseam, and would explain the absurdly high
values reported by syzbot (86, 149). VincentG noted there is value in
letting sd->cache_nice_tries grow, so the shift itself should be
fixed. That means preventing:
"""
If the value of the right operand is negative or is greater than or equal
to the width of the promoted left operand, the behavior is undefined.
"""
Thus we need to cap the shift exponent to
BITS_PER_TYPE(typeof(lefthand)) - 1.
I had a look around for other similar cases via coccinelle:
@expr@
position pos;
expression E1;
expression E2;
@@
(
E1 >> E2@pos
|
E1 >> E2@pos
)
@cst depends on expr@
position pos;
expression expr.E1;
constant cst;

(
E1 >> cst@pos

E1 << cst@pos
)
@script:python depends on !cst@
pos << expr.pos;
exp << expr.E2;
@@
# Dirty hack to ignore constexpr
if exp.upper() != exp:
coccilib.report.print_report(pos[0], "Possible UB shift here")
The only other match in kernel/sched is rq_clock_thermal() which employs
sched_thermal_decay_shift, and that exponent is already capped to 10, so
that one is fine.

sched/features: Fix hrtick reprogramming
[ Upstream commit 156ec6f42b8d300dbbf382738ff35c8bad8f4c3a ]
Hung tasks and RCU stall cases were reported on systems which were not
100% busy. Investigation of such unexpected cases (no sign of potential
starvation caused by tasks hogging the system) pointed out that the
periodic sched tick timer wasn't serviced anymore after a certain point
and that caused all machinery that depends on it (timers, RCU, etc.) to
stop working as well. This issues was however only reproducible if
HRTICK was enabled.
Looking at core dumps it was found that the rbtree of the hrtimer base
used also for the hrtick was corrupted (i.e. next as seen from the base
root and actual leftmost obtained by traversing the tree are different).
Same base is also used for periodic tick hrtimer, which might get "lost"
if the rbtree gets corrupted.
Much alike what described in commit

sched/deadline: Fix sched_dl_global_validate()
[ Upstream commit a57415f5d1e43c3a5c5d412cd85e2792d7ed9b11 ]
When change sched_rt_{runtime, period}_us, we validate that the new
settings should at least accommodate the currently allocated -dl
bandwidth:
sched_rt_handler()
--> sched_dl_bandwidth_validate()
{
new_bw = global_rt_runtime()/global_rt_period();
for_each_possible_cpu(cpu) {
dl_b = dl_bw_of(cpu);
if (new_bw < dl_b->total_bw) <-------
ret = -EBUSY;
}
}
But under CONFIG_SMP, dl_bw is per root domain , but not per CPU,
dl_b->total_bw is the allocated bandwidth of the whole root domain.
Instead, we should compare dl_b->total_bw against "cpus*new_bw",
where 'cpus' is the number of CPUs of the root domain.
Also, below annotation(in kernel/sched/sched.h) implied implementation
only appeared in SCHED_DEADLINE v2[1], then deadline scheduler kept
evolving till got merged(v9), but the annotation remains unchanged,
meaningless and misleading, update it.
* With respect to SMP, the bandwidth is given on a per-CPU basis,
* meaning that:
* - dl_bw (< 100%) is the bandwidth of the system (group) on each CPU;
* - dl_total_bw array contains, in the i-eth element, the currently
* allocated bandwidth on the i-eth CPU.

ANDROID: cpu/hotplug: add migration to paused_cpus
paused_cpus intending to force CPUs to go idle as quickly as possible, adding a migration step, to drain the rq from any running task. Two steps are actually needed. The first one, "lazy", will run before the cpu_active_mask has been synced. The second one will run after. It is possible for another CPU, to observe an outdated version of that mask and to enqueue a task on a rq that has just been marked inactive. The second migration is there to catch any of those spurious move, while the first one will drain the rq as quickly as possible to let the CPU reach an idle state.

sched: Add a tracepoint to track rq->nr_running
Add a bare tracepoint trace_sched_update_nr_running_tp which tracks ->nr_running CPU's rq. This is used to accurately trace this data and provide a visualization of scheduler imbalances in, for example, the form of a heat map. The tracepoint is accessed by loading an external kernel module. An example module (forked from Qais' module and including the pelt related tracepoints) can be found at: https://github.com/auldp/tracepoints-helpers.git A script to turn the trace-cmd report output into a heatmap plot can be found at: https://github.com/jirvoz/plot-nr-running The tracepoints are added to add_nr_running() and sub_nr_running() which are in kernel/sched/sched.h. In order to avoid CREATE_TRACE_POINTS in the header a wrapper call is used and the trace/events/sched.h include is moved before sched.h in kernel/sched/core.

sched/uclamp: Protect uclamp fast path code with static key
There is a report that when uclamp is enabled, a netperf UDP test
regresses compared to a kernel compiled without uclamp.
https://lore.kernel.org/lkml/20200529100806.GA3070@suse.de/
While investigating the root cause, there were no sign that the uclamp
code is doing anything particularly expensive but could suffer from bad
cache behavior under certain circumstances that are yet to be
understood.
https://lore.kernel.org/lkml/20200616110824.dgkkbyapn3io6wik@e107158-lin/
To reduce the pressure on the fast path anyway, add a static key that is
by default will skip executing uclamp logic in the
enqueue/dequeue_task() fast path until it's needed.
As soon as the user start using util clamp by:
1. Changing uclamp value of a task with sched_setattr()
2. Modifying the default sysctl_sched_util_clamp_{min, max}
3. Modifying the default cpu.uclamp.{min, max} value in cgroup
We flip the static key now that the user has opted to use util clamp.
Effectively re-introducing uclamp logic in the enqueue/dequeue_task()
fast path. It stays on from that point forward until the next reboot.
This should help minimize the effect of util clamp on workloads that
don't need it but still allow distros to ship their kernels with uclamp
compiled in by default.
SCHED_WARN_ON() in uclamp_rq_dec_id() was removed since now we can end
up with unbalanced call to uclamp_rq_dec_id() if we flip the key while
a task is running in the rq. Since we know it is harmless we just
quietly return if we attempt a uclamp_rq_dec_id() when
rq->uclamp[].bucket[].tasks is 0.
In schedutil, we introduce a new uclamp_is_enabled() helper which takes
the static key into account to ensure RT boosting behavior is retained.
The following results demonstrates how this helps on 2 Sockets Xeon E5
2x10-Cores system.

sched, vmlinux.lds: Increase STRUCT_ALIGNMENT to 64 bytes for GCC-4.9
For some mysterious reason GCC-4.9 has a 64 byte section alignment for
structures, all other GCC versions (and Clang) tested (including 4.8
and 5.0) are fine with the 32 bytes alignment.
Getting this right is important for the new SCHED_DATA macro that
creates an explicitly ordered array of 'struct sched_class' in the
linker script and expect pointer arithmetic to work.

sched/deadline: Make DL capacity-aware
The current SCHED_DEADLINE (DL) scheduler uses a global EDF scheduling algorithm w/o considering CPU capacity or task utilization. This works well on homogeneous systems where DL tasks are guaranteed to have a bounded tardiness but presents issues on heterogeneous systems. A DL task can migrate to a CPU which does not have enough CPU capacity to correctly serve the task (e.g. a task w/ 70ms runtime and 100ms period on a CPU w/ 512 capacity). Add the DL fitness function dl_task_fits_capacity() for DL admission control on heterogeneous systems. A task fits onto a CPU if: CPU original capacity / 1024 >= task runtime / task deadline Use this function on heterogeneous systems to try to find a CPU which meets this criterion during task wakeup, push and offline migration. On homogeneous systems the original behavior of the DL admission control should be retained.

sched/deadline: Improve admission control for asymmetric CPU capacities
The current SCHED_DEADLINE (DL) admission control ensures that sum of reserved CPU bandwidth < x * M where x = /proc/sys/kernel/sched_rt_{runtime,period}_us M = # CPUs in root domain. DL admission control works well for homogeneous systems where the capacity of all CPUs are equal (1024). I.e. bounded tardiness for DL and non-starvation of non-DL tasks is guaranteed. But on heterogeneous systems where capacity of CPUs are different it could fail by over-allocating CPU time on smaller capacity CPUs. On an Arm big.LITTLE/DynamIQ system DL tasks can easily starve other tasks making it unusable. Fix this by explicitly considering the CPU capacity in the DL admission test by replacing M with the root domain CPU capacity sum.
