UPSTREAM: sched/psi: Fix OOB write when writing 0 bytes to PSI files
Issuing write() with count parameter set to 0 on any file under
/proc/pressure/ will cause an OOB write because of the access to
buf[buf_size-1] when NUL-termination is performed. Fix this by checking
for buf_size to be non-zero.

UPSTREAM: psi: Fix a division error in psi poll()
The psi window size is a u64 an can be up to 10 seconds right now,
which exceeds the lower 32 bits of the variable. We currently use
div_u64 for it, which is meant only for 32-bit divisors. The result is
garbage pressure sampling values and even potential div0 crashes.
Use div64_u64.

The crashing instruction is trying to divide the observed stall time
by the sampling period. The period, stored in R8, is not 0, but we are
dividing by the lower 32 bits only, which are all 0 in this instance.
We could switch to a 64-bit division, but the period shouldn't be that
big in the first place. It's the time between the last update and the
next scheduled one, and so should always be around 2s and comfortably
fit into 32 bits.
The bug is in the initialization of new cgroups: we schedule the first
sampling event in a cgroup as an offset of sched_clock(), but fail to
initialize the last_update timestamp, and it defaults to 0. That
results in a bogusly large sampling period the first time we run the
sampling code, and consequently we underreport pressure for the first
2s of a cgroup's life. But worse, if sched_clock() is sufficiently
advanced on the system, and the user gets unlucky, the period's lower
32 bits can all be 0 and the sampling division will crash.
Fix this by initializing the last update timestamp to the creation
time of the cgroup, thus correctly marking the start of the first
pressure sampling period in a new cgroup.

UPSTREAM: sched/psi: Correct overly pessimistic size calculation
When passing a equal or more then 32 bytes long string to psi_write(),
psi_write() copies 31 bytes to its buf and overwrites buf[30]
with '\0'. Which makes the input string 1 byte shorter than
it should be.
Fix it by copying sizeof(buf) bytes when nbytes >= sizeof(buf).
This does not cause problems in normal use case like:
"some 500000 10000000" or "full 500000 10000000" because they
are less than 32 bytes in length.
/* assuming nbytes == 35 */
char buf[32];
buf_size = min(nbytes, (sizeof(buf) - 1)); /* buf_size = 31 */
if (copy_from_user(buf, user_buf, buf_size))
return -EFAULT;
buf[buf_size - 1] = '\0'; /* buf[30] = '\0' */

ANDROID: Disable wq fp check in CFI builds
With non-canonical CFI, LLVM generates jump table entries for external symbols in modules and as a result, a function pointer passed from a module to the core kernel will have a different address.

UPSTREAM: sched/topology: Introduce a sysctl for Energy Aware Scheduling
In its current state, Energy Aware Scheduling (EAS) starts automatically
on asymmetric platforms having an Energy Model (EM). However, there are
users who want to have an EM (for thermal management for example), but
don't want EAS with it.
In order to let users disable EAS explicitly, introduce a new sysctl
called 'sched_energy_aware'. It is enabled by default so that EAS can
start automatically on platforms where it makes sense. Flipping it to 0
rebuilds the scheduling domains and disables EAS.

UPSTREAM: sched/fair/util_est: Implement faster ramp-up EWMA on utilization increases
The estimated utilization for a task:
util_est = max(util_avg, est.enqueue, est.ewma)
is defined based on:
- util_avg: the PELT defined utilization
- est.enqueued: the util_avg at the end of the last activation
- est.ewma: a exponential moving average on the est.enqueued samples
According to this definition, when a task suddenly changes its bandwidth
requirements from small to big, the EWMA will need to collect multiple
samples before converging up to track the new big utilization.
This slow convergence towards bigger utilization values is not
aligned to the default scheduler behavior, which is to optimize for
performance. Moreover, the est.ewma component fails to compensate for
temporarely utilization drops which spans just few est.enqueued samples.
To let util_est do a better job in the scenario depicted above, change
its definition by making util_est directly follow upward motion and
only decay the est.ewma on downward.

ANDROID: Re-use SUGOV_RT_MAX_FREQ to control uclamp rt behavior
By default uclamp RT tasks will use the max frequency, which is not the desired default behavior on mobile devices. Re-use the SUGOV_RT_MAX_FREQ sched_feat to control the default behavior. When SUGOV_RT_MAX_FREQ is NOT selected, the uclamp_min value of the RT tasks will be 0. Note, since now we use SUGOV_RT_MAX_FREQ to enforce the default max frequency for RT when uclamp is compiled in; the condition in schedutil_cpu_util() needs to be inverted so that max no longer unconditionally applied when uclamp is compiled in && SUGOV_RT_MAX_FREQ is true. This unconditional application means uclamp values are always ignored which is not what we want when uclamp is compiled in.

BACKPORT: sched/fair: Make EAS wakeup placement consider uclamp restrictions
task_fits_capacity() has just been made uclamp-aware, and
find_energy_efficient_cpu() needs to go through the same treatment.
Things are somewhat different here however - using the task max clamp isn't
sufficient. Consider the following setup:
The target runqueue, rq:
rq.cpu_capacity_orig = 512
rq.cfs.avg.util_avg = 200
rq.uclamp.max = 768 // the max p.uclamp.max of all enqueued p's is 768
The waking task, p (not yet enqueued on rq):
p.util_est = 600
p.uclamp.max = 100
Now, consider the following code which doesn't use the rq clamps:
util = uclamp_task_util(p);
// Does the task fit in the spare CPU capacity?
cpu = cpu_of(rq);
fits_capacity(util, cpu_capacity(cpu) - cpu_util(cpu))
This would lead to:
util = 100;
fits_capacity(100, 512 - 200)
fits_capacity() would return true. However, enqueuing p on that CPU *will*
cause it to become overutilized since rq clamp values are max-aggregated,
so we'd remain with
rq.uclamp.max = 768
which comes from the other tasks already enqueued on rq. Thus, we could
select a high enough frequency to reach beyond 0.8 * 512 utilization
(== overutilized) after enqueuing p on rq. What find_energy_efficient_cpu()
needs here is uclamp_rq_util_with() which lets us peek at the future
utilization landscape, including rq-wide uclamp values.
Make find_energy_efficient_cpu() use uclamp_rq_util_with() for its
fits_capacity() check. This is in line with what compute_energy() ends up
using for estimating utilization.
[QP: moved changes to select_cpu_candidates(), which is the equivalent
to the mainline path, and fix missing dependency on fits_capacity() by
using the open coded version]

BACKPORT: sched/fair: Make task_fits_capacity() consider uclamp restrictions
task_fits_capacity() drives CPU selection at wakeup time, and is also used
to detect misfit tasks. Right now it does so by comparing task_util_est()
with a CPU's capacity, but doesn't take into account uclamp restrictions.
There's a few interesting uses that can come out of doing this. For
instance, a low uclamp.max value could prevent certain tasks from being
flagged as misfit tasks, so they could merrily remain on low-capacity CPUs.
Similarly, a high uclamp.min value would steer tasks towards high capacity
CPUs at wakeup (and, should that fail, later steered via misfit balancing),
so such "boosted" tasks would favor CPUs of higher capacity.
Introduce uclamp_task_util() and make task_fits_capacity() use it.
[QP: fixed missing dependency on fits_capacity() by using the open coded
alternative]

ANDROID: sched/core: Add a latency-sensitive flag to uclamp
Add a 'latency_sensitive' flag to uclamp in order to express the need for some tasks to find a CPU where they can wake-up quickly. This is not expected to be used without cgroup support, so add solely a cgroup interface for it. As this flag represents a boolean attribute and not an amount of resources to be shared, it is not clear what the delegation logic should be. As such, it is kept simple: every new cgroup starts with latency_sensitive set to false, regardless of the parent. In essence, this is similar to SchedTune's prefer-idle flag which was used in android-4.19 and prior.

ANDROID: sched/tune: Move SchedTune cpu API into UtilClamp wrappers
The SchedTune CPU boosting API is currently used from sugov_get_util() to get the boosted utilization and to pass it into schedutil_cpu_util(). When UtilClamp is in use instead we call schedutil_cpu_util() by passing in just the CFS utilization and the clamping is done internally on the aggregated CFS+RT utilization for FREQUENCY_UTIL calls. This asymmetry is not required moreover, schedutil code is polluted by non-mainline SchedTune code. Wrap SchedTune API call related to cpu utilization boosting with a more generic and mainlinish UtilClamp call: - uclamp_rq_util_with(cpu, util, p) <= boosted_cpu_util(cpu) This new API is already used in schedutil_cpu_util() to clamp the aggregated RT+CFS utilization on FREQUENCY_UTIL calls. Move the cpu boosting into uclamp_rq_util_with() so that we remove any SchedTune specific bit from kernel/sched/cpufreq_schedutil.c. Get rid of the no more required boosted_cpu_util(cpu) method and replace it with a stune_util(cpu, util) which signature is better aligned with its uclamp_rq_util_with(cpu, util, p) counterpart.

FROMGIT: sched/uclamp: Fix a bug in propagating uclamp value in new cgroups
When a new cgroup is created, the effective uclamp value wasn't updated
with a call to cpu_util_update_eff() that looks at the hierarchy and
update to the most restrictive values.
Fix it by ensuring to call cpu_util_update_eff() when a new cgroup
becomes online.
Without this change, the newly created cgroup uses the default
root_task_group uclamp values, which is 1024 for both uclamp_{min, max},
which will cause the rq to to be clamped to max, hence cause the
system to run at max frequency.
The problem was observed on Ubuntu server and was reproduced on Debian
and Buildroot rootfs.
By default, Ubuntu and Debian create a cpu controller cgroup hierarchy
and add all tasks to it - which creates enough noise to keep the rq
uclamp value at max most of the time. Imitating this behavior makes the
problem visible in Buildroot too which otherwise looks fine since it's a
minimal userspace.

BACKPORT: sched/rt: Make RT capacity-aware
Capacity Awareness refers to the fact that on heterogeneous systems
(like Arm big.LITTLE), the capacity of the CPUs is not uniform, hence
when placing tasks we need to be aware of this difference of CPU
capacities.
In such scenarios we want to ensure that the selected CPU has enough
capacity to meet the requirement of the running task. Enough capacity
means here that capacity_orig_of(cpu) >= task.requirement.
The definition of task.requirement is dependent on the scheduling class.
For CFS, utilization is used to select a CPU that has >= capacity value
than the cfs_task.util.
capacity_orig_of(cpu) >= cfs_task.util
DL isn't capacity aware at the moment but can make use of the bandwidth
reservation to implement that in a similar manner CFS uses utilization.
The following patchset implements that:
https://lore.kernel.org/lkml/20190506044836.2914-1-luca.abeni@santannapisa.it/
capacity_orig_of(cpu)/SCHED_CAPACITY >= dl_deadline/dl_runtime
For RT we don't have a per task utilization signal and we lack any
information in general about what performance requirement the RT task
needs. But with the introduction of uclamp, RT tasks can now control
that by setting uclamp_min to guarantee a minimum performance point.
ATM the uclamp value are only used for frequency selection; but on
heterogeneous systems this is not enough and we need to ensure that the
capacity of the CPU is >= uclamp_min. Which is what implemented here.
capacity_orig_of(cpu) >= rt_task.uclamp_min
Note that by default uclamp.min is 1024, which means that RT tasks will
always be biased towards the big CPUs, which make for a better more
predictable behavior for the default case.
Must stress that the bias acts as a hint rather than a definite
placement strategy. For example, if all big cores are busy executing
other RT tasks we can't guarantee that a new RT task will be placed
there.
On non-heterogeneous systems the original behavior of RT should be
retained. Similarly if uclamp is not selected in the config.
