[Symptom]
The fair server mechanism, which is intended to prevent fair starvation
when higher-priority tasks monopolize the CPU.
Specifically, RT tasks on the runqueue may not be scheduled as expected.
[Analysis]
---------
The log "sched: DL replenish lagged too much" triggered.
By memory dump of dl_server:
--------------
curr = 0xFFFFFF80D6A0AC00 (
dl_server = 0xFFFFFF83CD5B1470(
dl_runtime = 0x02FAF080,
dl_deadline = 0x3B9ACA00,
dl_period = 0x3B9ACA00,
dl_bw = 0xCCCC,
dl_density = 0xCCCC,
runtime = 0x02FAF080,
deadline = 0x0000082031EB0E80,
flags = 0x0,
dl_throttled = 0x0,
dl_yielded = 0x0,
dl_non_contending = 0x0,
dl_overrun = 0x0,
dl_server = 0x1,
dl_server_active = 0x1,
dl_defer = 0x1,
dl_defer_armed = 0x0,
dl_defer_running = 0x1,
dl_timer = (
node = (
expires = 0x000008199756E700),
_softexpires = 0x000008199756E700,
function = 0xFFFFFFDB9AF44D30 = dl_task_timer,
base = 0xFFFFFF83CD5A12C0,
state = 0x0,
is_rel = 0x0,
is_soft = 0x0,
clock_update_flags = 0x4,
clock = 0x000008204A496900,
- The timer expiration time (rq->curr->dl_server->dl_timer->expires)
is already in the past, indicating the timer has expired.
- The timer state (rq->curr->dl_server->dl_timer->state) is 0.
[Suspected Root Cause]
--------------------
The relevant code flow in the throttle path of
update_curr_dl_se() as follows:
dequeue_dl_entity(dl_se, 0); // the DL entity is dequeued
if (unlikely(is_dl_boosted(dl_se) || !start_dl_timer(dl_se))) {
if (dl_server(dl_se)) // timer registration fails
enqueue_dl_entity(dl_se, ENQUEUE_REPLENISH);//enqueue immediately
...
}
The failure of `start_dl_timer` is caused by attempting to register a
timer with an expiration time that is already in the past. When this
situation persists, the code repeatedly re-enqueues the DL entity
without properly replenishing or restarting the timer, resulting in RT
task may not be scheduled as expected.
[Proposed Solution]:
------------------
Instead of immediately re-enqueuing the DL entity on timer registration
failure, this change ensures the DL entity is properly replenished and
the timer is restarted, preventing RT potential starvation.

(cherry picked from commit 6b836537975d54fdd0ed6f711ca325d2c2580bd5)
We found a stability issue in current code of scx_ops_disable_workfn
founction. When SCX_OPS_DISABLING VH is invoked, system may keeps
forking fair tasks. In this circumstances, if scx_ops_disable_workfn
is blocked by scx_fork_rwsem, it may never running again because the
task who invoking scx_ops_disable_workfn is scx task.
So we move the SCX_OPS_DISABLING VH inside scx_fork_rwsem section.
This patchset ensures that if the scx task who invoking
scx_ops_disable_workfn is blocked by scx_fork_rwsem, the system will
not produce fair task. This can avoid the stability issue caused in
scx disabling process.

(cherry picked from commit ad3375325ca2ff7356bdea0adec021abc29e23ff)
When the PLACE_LAG scheduling feature is enabled and
dst_cfs_rq->nr_queued is greater than 1, if a task is
ineligible (lag < 0) on the source cpu runqueue, it will
also be ineligible when it is migrated to the destination
cpu runqueue. Because we will keep the original equivalent
lag of the task in place_entity(). So if the task was
ineligible before, it will still be ineligible after
migration.
So in sched_balance_rq(), we prioritize migrating eligible
tasks, and we soft-limit ineligible tasks, allowing them
to migrate only when nr_balance_failed is non-zero to
avoid load-balancing trying very hard to balance the load.
Below are some benchmark test results. From my test results,
this patch shows a slight improvement on hackbench.
Benchmark
=========
All of the benchmarks are done inside a normal cpu cgroup in a
clean environment with cpu turbo disabled, and test machine is:
Single NUMA machine model is 13th Gen Intel(R) Core(TM)
i7-13700, 12 Core/24 HT.
Based on master b86545e02e8c.

Vendor might want to change task's data when they are moved from other
sched_class to scx sched_class. Add vendor hook to give control to
vendor to implement what they need.
The vendor may have its own scheduling algorithm that can coexist
with SCX and manages all other scheduler sched_class (except the
SCX sched_class).
When SCX is enabled, some tasks(such as all fair tasks) are migrated
from other sched_class (managed by the vendor's algorithm) to the SCX
sched_class. During this migration, it's necessary to reset the vendor
scheduler's historical data for these tasks. Otherwise, inconsistencies
in the data may cause a panic. This is because, depending on the
scenario, some tasks may frequently switch between the SCX sched_class
and other sched_class (such as the RT sched_class). If a task switches
back from the SCX sched_class to another sched_class while still
retaining outdated data from the vendor scheduler, the
desynchronization may trigger a panic.

Delayed dequeued feature keeps a sleeping task enqueued until its
lag has elapsed. As a result, it stays also visible in rq->nr_running.
So when in wake_affine_idle(), we should use the real running-tasks
in rq to check whether we should place the wake-up task to
current cpu.
On the other hand, add a helper function to return the nr-delayed.

In doing some testing, I caught a few build issues with
different combinations of enabling and disabling
CONFIG_SCHED_PROXY_EXEC and CONFIG_SMP after syncing
with the v18 of the proxy-exec series.
These fixes were not in the v18 series of the patch, but
I've included them in my tree for v19.

This updates the proxy-exec logic in android16-6.12
which was added at v14, to be synced with the v18
series of the patchset.
v14 series:
https://github.com/johnstultz-work/linux-dev/commits/proxy-exec-v14-6.12
v18 series:
https://github.com/johnstultz-work/linux-dev/commits/proxy-exec-v18-6.12
Changes since v14:
* Improved naming consistency and using the guard macro where
appropriate
* Improved comments
* Build fixes for !CONFIG_SMP
* Fixes for when sched_proxy_exec() is disabled
* Renamed update_curr_se to update_se_times, as suggested by
Steven Rostedt.
* Use put_prev_set_next_task as suggested by K Prateek Nayak
* Try to rework find_proxy_task() locking to use guard and
proxy_deactivate_task() in the way Peter suggested.
* Simplified changes to enqueue_task_rt to match deadline's
logic, as pointed out by Peter
* Get rid of preserve_need_resched flag and rework per Peter's
suggestion
* Rework find_proxy_task() to use guard to cleanup the exit
gotos as Peter suggested.
* Reworked the forced return-migration from find_proxy_task to
use Peter’s dequeue+wakeup approach, which helps resolve the
cpuhotplug issues I had also seen, caused by the manual return
migration sending tasks to offline cpus.
* A number of improvements to the commit messages and comments
suggested by Juri Lelli and Peter Zijlstra
* Added missing logic to put_prev_task_dl as pointed out by
K Prateek Nayak
* Add lockdep_assert_held_once and drop the READ_ONCE in
__get_task_blocked_on(), as suggested by Juri Lelli
* Moved update_curr_task logic into update_curr_se to simplify
things
* Renamed update_se_times to update_se, as suggested by Peter
* Reworked logic to fix an issue Peter pointed out with thread
group accounting being done on the donor, rather than the
running execution context.
* Fixed typos caught by Metin Kaya
* Suleiman Souhlal noticed an inefficiency in that we evaluate
if the lock owner’s task_cpu() is the current cpu, before we
look to see if the lock owner is on_rq at all. With v17 this
would result in us proxy-migrating a donor to a remote cpu,
only to then realize the task wasn’t even on the runqueue,
and doing the sleeping owner enqueuing. Suleiman suggested
instead that we evaluate on_rq first, so we can immediately do
sleeping owner enqueueing. Then only if the owner is on a
runqueue do we proxy-migrate the donor (which requires the
more costly lock juggling). While not a huge logical change,
it did uncover other problems, which needed to be resolved.
* One issue found was there was a race where if
do_activate_blocked_waiter() from the sleeping owner wakeup
was delayed and the task had already been woken up elsewhere.
It’s possible if that task was running and called into
schedule() to be blocked, it would be dequeued from the
runqueue, but before we switched to the new task,
do_activate_blocked_waiter() might try to activate it on a
different cpu. Clearly the do_activate_blocked_waiter() needed
to check the task on_cpu value as well.
* I found that we still can hit wakeups that end up skipping the
BO_WAKING -> BO_RUNNALBE transition (causing find_proxy_task()
to end up spinning waiting for that transition), so I re-added
the logic to handle doing return migrations from
find_proxy_task() if we hit that case.
* Hupu suggested a tweak in ttwu_runnable() to evaluate
proxy_needs_return() slightly earlier.
* Kuyo Chang reported and isolated a fix for a problem with
__task_is_pushable() in the !sched_proxy_exec case, which was
folded into the “sched: Fix rt/dl load balancing via chain
level balance” patch
* Reworked some of the logic around releasing the rq->donor
reference on migrations, using rq->idle directly.
* Sueliman also pointed out that some added task_struct elements
were not being initialized in the init_task code path, so that
was good to fix.

In our testing with 6.12 based kernel on a big.LITTLE system, we were
seeing instances of RT tasks being blocked from running on the LITTLE
cpus for multiple seconds of time, apparently by the dl_server. This
far exceeds the default configured 50ms per second runtime.
This is due to the fair dl_server runtime calculation being scaled
for frequency & capacity of the cpu.
Consider the following case under a Big.LITTLE architecture:
Assume the runtime is: 50,000,000 ns, and Frequency/capacity
scale-invariance defined as below:
Frequency scale-invariance: 100
Capacity scale-invariance: 50
First by Frequency scale-invariance,
the runtime is scaled to 50,000,000 * 100 >> 10 = 4,882,812
Then by capacity scale-invariance,
it is further scaled to 4,882,812 * 50 >> 10 = 238,418.
So it will scaled to 238,418 ns.
This smaller "accounted runtime" value is what ends up being
subtracted against the fair-server's runtime for the current period.
Thus after 50ms of real time, we've only accounted ~238us against the
fair servers runtime. This 209:1 ratio in this example means that on
the smaller cpu the fair server is allowed to continue running,
blocking RT tasks, for over 10 seconds before it exhausts its supposed
50ms of runtime. And on other hardware configurations it can be even
worse.
For the fair deadline_server, to prevent realtime tasks from being
unexpectedly delayed, we really do want to use fixed time, and not
scaled time for smaller capacity/frequency cpus. So remove the scaling
from the fair server's accounting to fix this.

So this balance_push() is part of schedule(), and schedule() is supposed
to switch to stopper task, but because of this race condition, stopper
task is stuck in WAKING state and not actually visible to be picked.
Therefore CPU1 can do another schedule() and end up doing another
balance_push() even though the last one hasn't been done yet.
This is a confluence of fail, where both wake_q and ttwu_wakelist can
cause crucial wakeups to be delayed, resulting in the malfunction of
balance_push.
Since there is only a single stopper thread to be woken, the wake_q
doesn't really add anything here, and can be removed in favour of
direct wakeups of the stopper thread.
Then add a clause to ttwu_queue_cond() to ensure the stopper threads
are never queued / delayed.
Of all 3 moving parts, the last addition was the balance_push()
machinery, so pick that as the point the bug was introduced.

commit 33796b91871ad4010c8188372dd1faf97cf0f1c0 upstream.
During task_group creation, sched_create_group() calls
scx_group_set_weight() with CGROUP_WEIGHT_DFL to initialize the sched_ext
portion. This is premature and ends up calling ops.cgroup_set_weight() with
an incorrect @cgrp before ops.cgroup_init() is called.
sched_create_group() should just initialize SCX related fields in the new
task_group. Fix it by factoring out scx_tg_init() from sched_init() and
making sched_create_group() call that function instead of
scx_group_set_weight().
v2: Retain CONFIG_EXT_GROUP_SCHED ifdef in sched_init() as removing it leads
to build failures on !CONFIG_GROUP_SCHED configs.

[ Upstream commit b7ca5743a2604156d6083b88cefacef983f3a3a6 ]
It was reported that in 6.12, smpboot_create_threads() was
taking much longer then in 6.6.
I narrowed down the call path to:
smpboot_create_threads()
-> kthread_create_on_cpu()
-> kthread_bind()
-> __kthread_bind_mask()
->wait_task_inactive()
Where in wait_task_inactive() we were regularly hitting the
queued case, which sets a 1 tick timeout, which when called
multiple times in a row, accumulates quickly into a long
delay.
I noticed disabling the DELAY_DEQUEUE sched feature recovered
the performance, and it seems the newly create tasks are usually
sched_delayed and left on the runqueue.
So in wait_task_inactive() when we see the task
p->se.sched_delayed, manually dequeue the sched_delayed task
with DEQUEUE_DELAYED, so we don't have to constantly wait a
tick.

Chris reported that commit 5f6bd380c7 ("sched/rt: Remove default
bandwidth control") caused a significant dip in his favourite
benchmark of the day. Simply disabling dl_server cured things.
His workload hammers the 0->1, 1->0 transitions, and the
dl_server_{start,stop}() overhead kills it -- fairly obviously a bad
idea in hind sight and all that.
Change things around to only disable the dl_server when there has not
been a fair task around for a whole period. Since the default period
is 1 second, this ensures the benchmark never trips this, overhead
gone.

[ Upstream commit 2ae891b826958b60919ea21c727f77bcd6ffcc2c ]
The old default value for slice is 0.75 msec * (1 + ilog(ncpus)) which
means that we have a default slice of:
0.75 for 1 cpu
1.50 up to 3 cpus
2.25 up to 7 cpus
3.00 for 8 cpus and above.
For HZ=250 and HZ=100, because of the tick accuracy, the runtime of
tasks is far higher than their slice.
For HZ=1000 with 8 cpus or more, the accuracy of tick is already
satisfactory, but there is still an issue that tasks will get an extra
tick because the tick often arrives a little faster than expected. In
this case, the task can only wait until the next tick to consider that it
has reached its deadline, and will run 1ms longer.
vruntime + sysctl_sched_base_slice = deadline
|-----------|-----------|-----------|-----------|
1ms 1ms 1ms 1ms
^ ^ ^ ^
tick1 tick2 tick3 tick4(nearly 4ms)
There are two reasons for tick error: clockevent precision and the
CONFIG_IRQ_TIME_ACCOUNTING/CONFIG_PARAVIRT_TIME_ACCOUNTING. with
CONFIG_IRQ_TIME_ACCOUNTING every tick will be less than 1ms, but even
without it, because of clockevent precision, tick still often less than
1ms.
In order to make scheduling more precise, we changed 0.75 to 0.70,
Using 0.70 instead of 0.75 should not change much for other configs
and would fix this issue:
0.70 for 1 cpu
1.40 up to 3 cpus
2.10 up to 7 cpus
2.8 for 8 cpus and above.
This does not guarantee that tasks can run the slice time accurately
every time, but occasionally running an extra tick has little impact.

commit 428dc9fc0873989d73918d4a9cc22745b7bbc799 upstream.
BPF programs may call next() and destroy() on BPF iterators even after new()
returns an error value (e.g. bpf_for_each() macro ignores error returns from
new()). bpf_iter_scx_dsq_new() could leave the iterator in an uninitialized
state after an error return causing bpf_iter_scx_dsq_next() to dereference
garbage data. Make bpf_iter_scx_dsq_new() always clear $kit->dsq so that
next() and destroy() become noops.
