[RFC 0/6] optimize ctx switch with rb-tree

[RFC 0/6] optimize ctx switch with rb-tree

[David Carrillo-Cisneros]

Following the discussion in:
https://patchwork.kernel.org/patch/9420035/

This is is an early version of a series of perf context switches
optimizations.

The main idea is to create and maintain a list of inactive events sorted
by timestamp, and a rb-tree index to index it. The rb-tree's key are
{cpu,flexible,stamp} for task contexts and {cgroup,flexible,stamp}
for CPU contexts.

The rb-tree provides functions to find intervals in the inactive event
list so that ctx_sched_in only has to visit the events that can be
potentially be scheduled (i.e. avoid iterations over events bound
to CPUs or cgroups that are not current).

Since the inactive list is sort by timestamp, rotation can be done by
simply scheduling out and in the events. This implies that each timer
interrupt, the events will rotate by q events (where q is the number
of hardware counters). This changes the current behavior of rotation.
Feedback welcome!

I haven't profiled the new approach. I am only assuming it will be
superior when the number of per-cpu or distict cgroup events is large.

The last patch shows how perf_iterate_ctx can use the new rb-tree index
to reduce the number of visited events. I haven't looked carefully if
locking and other things are correct.

If this changes are in the right direction. A next version could remove
some existing code, specifically the lists ctx->pinned_groups and
ctx->flexible_groups could be removed. Also, event_filter_match could be
simplified when called on events groups filtered using the rb-tree, since
both perform similar checks.

David Carrillo-Cisneros (6):
  perf/core: create active and inactive event groups
  perf/core: add a rb-tree index to inactive_groups
  perf/core: use rb-tree to sched in event groups
  perf/core: avoid rb-tree traversal when no inactive events
  perf/core: rotation no longer neccesary. Behavior has changed. Beware
  perf/core: use rb-tree index to optimize filtered  perf_iterate_ctx

[RFC 1/6] perf/core: create active and inactive event groups

[David Carrillo-Cisneros]

Currently, perf uses pinned_groups and flexible_groups for sched in/out.
We can do better because:
  - sched out only cares about the ACTIVE events, this is usually a small
  set of events.
  - There can be many events in these lists thate are no relevant to
  the scheduler (e.g. other CPU/cgroups, events in OFF and ERROR state).

Reduce the set of events to iterate over each context switch by adding
three new lists: active_pinned_groups, active_flexible_groups and
inactive_groups. All events in each list are in the same state so we
avoid checking state. It also saves the iteration over events in OFF and
ERROR state during sched in/out.

The main impact of this patch is that ctx_sched_out can use the "small"
active_{pinned,flexible}_groups instead of the potentially much larger
{pinned,flexible}_groups.

There is no pinned/flexible version of inactive event because next patches
will create an index on them.

Bookkeeping of the new lists is more involved, but it can provide a
potentially large speed up. The new lists are intended to eventually
replace {pinned,flexible}_groups, although that's not yet implemented.

The inactive list is kept in FIFO order and only added after
group_sched_in has succeded. This guarantees that it's in timestamp
order.

[RFC 2/6] perf/core: add a rb-tree index to inactive_groups

[David Carrillo-Cisneros]

Add a rb-tree that indexes inactive events by {CPU/cgroup,flexible,stamp}.

The original idea by Peter Z. was to sort task events in an rb-tree using
{pmu,cpu,timestamp} as key.

Having the PMU as part of the key gets complicated for contexts that
share pmus (i.e. software context) because all events in a context should
rotate together irrespective of their pmu. It's also unclear to me that
there is any case where a seach by pmu is useful.

Another complicatino is that using ctx->time (or timestamp) implies that
groups added during the same context switch may not have unique key.
This increases the complexity of that finds all events in the rb-tree
that are within a time interval.

Lastly, it is useful to query pinned and flexible events separately since
they are scheduled in at different times.

For the reasons above, I created a rb-tree per context with key
{CPU,flexible,stamp} for task contexts and {cgroup,flexible,stamp} for
CPU contexts.

The "flexible" boolean allows to query pinned or flexible events
separately.
The stamp is given by a non-decreasing counter: ctx->nr_events_added.
It increases every time a new inactive event is inserted. That choice of
stamp guarantees unique keys for all events and that events of the same
type (same {CPU/cgroup,flexible}) have the same order in the rb-tree.

When events are scheduled in or rotated, all events in the context must be
iterated or rotated together, irrespective of the CPU/cgroup. To do that,
we add ctx->inactive_groups, a list that "threads" the rb-tree in total
ctx->nr_events_added order. Note that this order is the same as timestamp
order and ctx->inactive_groups is used for both scheduling and iteration.
The rb-tree can be seen as an index over ctx->inactive_groups.

[RFC 3/6] perf/core: use rb-tree to sched in event groups

[David Carrillo-Cisneros]

During sched in, only events that match the current CPU and cgroup can
be scheduled in. These events should be added to the PMU in increasing
timestamp order to guaratee fairness in the event rotation.

In task contexts, events with no CPU affinity or with affinity to the
current CPU are eligible.
In CPU contexts, events with no cgroup restriction (CPU events) or with
a cgroup that is current (either current's task cgroup or one of its
ancestor) are eligible.

For both context types, we need to iterate over events with different
rb-tree key groups (different CPUs or different cgroups) in timestamp
order.

Finding the events in timestamp order is at odds with indexing by
by CPU/cgroup. The rb-tree allows us to find events with minimum and
maximum timestamp for a given CPU/cgroup + flexible type. The list
ctx->inactive_groups is sorted by timestamp.

We could find a list position for the first event of each CPU/cgroup that
is to be scheduled and iterate over all of them, selecting events from
the list's head with the smallest timestampt, but it's too complicated.

A simpler alternative is to find the smallest subinterval of
ctx->inactive_groups that contains all eligible events. Let's call this
minimum subinterval S.

S is formed of smaller subintervals, no necessarily exclusive, intervals.
Each one has all the events that are eligible for a given CPU or cgroup.
We find S by searching for the start/end of each one of these CPU/cgroup
subintervals and combining them. The drawback is that there may be
events in S that are not eligible (since ctx->inactive_group is in stamp
order).
Yet, it is more efficient that it may look since the stamp of newly
inserted events is higher than events that are not eligible.
Eventually, events of ineligible CPU/cgroups are not longer part of S.

More formally, if:
  - n is the number of events in the context.
  - s is the number of eligible events.
  - q is the number of events scheduled each context switch.

Then, in the worst case, |S|=n in the first context switch and q events
are scheduled in and out. Events scheduled out are added at the end of
ctx->inactive_groups. The next sched in continues from the last
scheduled event, hence skipping all events that were found not eligible
in the previous context switch. Therefore, every context switch reduces
the size of |S| by an average of n/q and it takes up to ceiling(s/q)
context switches for all ineligible events to be visited once and
skipped. All subsequent context switches will have |S|=s.

Therefore, the worst case is linear and a not optimal case only
occurs when the criteria to elect events changes (i.e. CPU migration or
cgroup change).

[RFC 5/6] perf/core: rotation no longer necessary. Behavior has changed. Beware

[David Carrillo-Cisneros]

The sched in/out process updates timestamps and "rotates"
ctx->inactive_groups.

This changes the speed at which rotation happens. Before events will
rotate one event per interruption, now they will rotate q events each
timer interruption. Where q is the number of events added to the pmu per
sched in.

I think we should be able to kill off active_entry as part of this
series; it's there to do the same thing (optimize iteration over active
events).

If we expose a for_each_ctx_active_event() helper which iterates of the
pinned and flexible lists, I think we may be able to migrate existing
users over and kill off perf_event::active_entry, and the redundant list
manipulation in drivers.

... there might be some fun and games ordering manipulation against PMI
handlers, tough, so it may turn out that we need both.

... and here we'll subsequently delete most events from the inactive

It would be nicer to splti the definition from the intisation. That way

... and we can move the dereference of event after the check here.

That said, is there ever a risk of this being NULL? Won't the event have
to be the container of a list element we walked? Or is there a path
where that is not the case?

We didn't add a similar check to ctx_sched_groups_to_inactive(), so if
nothing else it seems inconsistent.

I take it this is because we always expect the event to be in the

I think IRQs are disabled in this path (though I'll need to
double-check), but I don't think the PMU is disabled, so I believe a PMI
can come in between the commit_txn() and the addition of events to their
active list.

I'm not immediately sure if that matters -- we'll need to consider what
list manipulation might happen in a PMI handler.

If it does matter, we could always add the events to an active list
first, then try the commit, then remove them if the commit failed. It
means we might see some not-actually-active events in the active lists
occasionally, but the lists would still be shorter than the full event
list.

I don't believe we need to initialise event here;
list_for_each_entry_safe() should do that as required.

Using the PMU as the key is essential for correct operation where
heterogeneous HW PMUs share a context.

For example, on a big.LITTLE system, big and little CPU PMUs share the
same context, but their events are mutually incompatible. On big CPUs we
only want to consider the sub-tree of big events, and on little CPUs we
only want to consider little events. Hence, we need to be abel to search
by PMU.

For SW PMUs, pmu::add() should never fail, and regardless of the order
of the list we should be able to pmu::add() all events. Given that, why
does the manner in which rotation occurs matter for SW PMUs?

Could you elaborate on this? I don't understand what the problem is
here. If we need uniqueness where {pmu,cpu,runtime} are equal, can't we
extend the comparison to {pmu,cpu,runtime,event pointer}? That way
everything we need is already implicit in the event, and we don't need
perf_event::rbtree_key nor do we need
perf_event_context::nr_inactive_added.

Using the runtime as part of the key was intended to provide fairer
scheduling, even when scheduling intervals are not uniform, etc. Not
using the runtime means we lose that fairness.

Using this as part of the sort makes sense to me.

As above, I think we can use the event pointer for this, without having
to maintain a new counter.

As above, I think we must use runtime as part of the key, and with that
done, we only need the rb tree, and not the inactive_groups list.

With runtime as part of the key, rotation is not necessary, since
insertion will sort the list, and then we can pick all the nodes with
the shortest runtime. Hence, no special rotation code is necessary -- we
simply make all events inactive, then reschedule.

Can we turn these info {task,cpu}ctx_rbtree_cmp() functions which
compare two events dynamically?

Given that event->task can distinguish the two cases, we could just have
a event_rbtree_cmp() (with an assert that event_a->task ==
event_b->task).

Mark.

That's a fair point. Sorting by CPU before runtime we'll get subtrees we
won't get fairness unless we sort the events solely by runtime at
sched_in time. If we sort by with runtime before CPU we'll have to skip
events not targeting the current CPU when scheduling task events in.  I
note the latter is true today anyhow.

In Peter's original suggestion we didn't sort by cgroup. IIRC there was
some email thread where the cgroup was considered for the sort (maybe
that was *only* for cpu contexts? I'm not too familiar with cgroups),
though I can't find the relevant mail, if it existed. :/

Peter, did you have an idea as to how to handle that, or am I imagining
things here?

Kan, in your per-cpu event list patch you mentioned that you saw a large
overhead in perf_iterate_ctx() when skipping events for other CPUs.
Which callers of perf_iterate_ctx() specifically was that problematic
for? Do those callers only care about the *active* events, for example?

Maybe the overhead of skipping !current_cpu events is ok at sched_in
time in most cases. If the overhead of skipping those only matters for a
subset of perf_iterate_ctx() callers, then maybe we can optimise them in
another fashion (e.g. use the active events lists, or a new list
specific to that iterate user, depending on what they actually need).
That way we can drop cpu from the sort.

The other drawback is that this is not fair, since CPU comes before
runtime in the sort order. You'll always try some events before others
(e.g. cpu == -1 before cpu == current), before considering runtime. I
believe this means that events can be permanently starved.

So either we need to fold those together somehow, or drop CPU from the
sort order (assuming that we can, as above).

Thanks,
Mark.

I see it now. So, if PMU were added to the rb-tree keys. How can the
generic code know what's the PMU of the current CPU?

Yes, we could extend the comparison. But I am trying to keep the key a
u64 to speed up things.

I found it easier to simply create a counter and use it as an equivalent to
(timestamp, unique id). Both ways induce the same order of events.

A counter that increases every time an event is added to the rbtree
induces the same order as a (timestamp, <some unique id>).

Same as above. I am trying to have a unique 64 bit key. I'd argue that
the new counter only adds a couple of lines of code and 32 bits of storage
but makes the rb-tree key comparison simpler and faster.

The inactive_groups list makes the rb-tree "threaded" and follows
timestamp (or stamp) order. It makes iterating over events much
faster.

Right, that's done later in this series.

I tried to avoid recreating the key every time there is a comparison.
Currently the key is stored into the u64 event->rbtree_key and only recreated
when the stamp changes.

The cmp wrapper makes sense if we go away from the u64 keys and add
more fields to the comparison.

In summary:

  - The stamp (i.e. ctx->nr_inactive_added) induces the same order than the
  timestamp at the time the event is added to the rb-tree. But it guarantees
  uniqueness and is denser (fits in 32bits).

  - The inactive_groups list threads the rb-tree and is sorted in stamp order
 (same as timestamp order). This is the list used to iterate during
ctx_sched_{in,out}.
 The rb-tree only creates a index (or skiplist) on these list so that we skip
  most of the events that do not mach the current CPU/cgroup (or pmu,
optionally).

  - I see now why PMU is useful for big.LITTLE. If there is a way for
generic code
  to retrieve the PMU of a CPU, I can add it to the key for those PMUs with
  PERF_PMU_CAP_HETEROGENEOUS_CPUS capability.

The problem with that would be iterating over all CPU contexts, when most
users of active_entry only install evens in one CPU per package/socket.

Maybe we can create yet another list of cpu contexts to have contexts with
at least one active event.

No, it's should never be NULL. I should've removed all this debug code

Just checked, the pmu is disabled from perf_event_context_sched_in, so

That's were ctx->inactive_groups comes in. That list is sorted by runtime
and the rb-tree is used to skip to the part of the list that has the events
that matter.

FWIW, in this approach, we only sort by cgroup in CPU contexts, since cgroup
events are only installed in CPU contexts.

We do that by iterating over ctx->inactive_groups, that is sorted by timestamp.
That's how we keep the fairness.

Based on my test, the large overhead was observed in perf_iterate_sb.
Yes, it only cares about the *active* events.

Great!

That should mean the first patch of this series (adding the active
events lists) should give us sufficient infrastructure to solve that
particular issue.

Ah. I thought these were already per-context rather than per-{pmu,box}.
My bad. I guess having bth isn't really a problem.

In all cases they're used by a hrtimer that iterates over events to
update them (and they're only used by uncore PMUs).

We could instead register a hrtimer affine to a cpu when the first event
was created, which would iterate over that CPU's events alone. When you
only have events on one CPU, that behaves the same. When you have events
on multiple CPUs, you avoid repeated cross-calls to update the events.

Unfortunately, that's not sufficient in all cases. Details below for the
'enjoyment' of all...

In some cases, several PMUs share the same task context, so events in a
context might be for a HW PMU other than ctx->pmu. Thus, the
perf_pmu_disable(ctx->pmu) in perf_event_context_sched_in() isn't
necessarily sufficient to disable the PMU that group_sched_in() is
operating on. AFAICT, the PMU is only necessarily disabled in the blcok
from start_txn() to {stop,cancel}_txn().

The reason for this is that each task can only have two contexts, a
perf_sw_context, and a perf_hw_context. Despite this, more than two HW
PMUs may have task-bound events, so they have to share.

For example, in systems with heterogeneous CPUs (like ARM's big.LITTLE),
we have a PMU per micro-architecture present in the system, and a user
may wish to open events for either microarchitecture. Those share the
same perf_hw_context.

For more fun, some HW tracing PMUs use perf_sw_context, which is very
counter-intuitive.

If any of those PMUs sharing a context can raise an NMI, then I believe
the problem I raised above stands. Currently the ARM PMU don't, but
there's ongoing work to implement NMIs for GICv3. I'm not sure about the
other PMUs.

This context sharing is problematic for a number of reasons outside of
scheduling. I had hoped to address this by reworking the way we handle
task contexts to avoid sharing. It turns out that there are many subtle
locking and ordering issues to consider for that, so I hadn't made much
headway with that approach.

Thanks,
Mark.

I'm not immediately sure.

We might need to augment struct pmu or perf_event_context with
information such that we can determine that. That's not something I'd
considered in great detail, and I'm not sure if peter had something in
mind.

As I mentioned before, I believe that Peter's intent was to consider
runtime, rather than a last-scheduled timestamp, so I don't think the
counter is equivalent. It might be that either way is fine; I'll leave
it to Peter to weigh in.

Do we have any benchmark figures either way?

Is the list only sorted by runtime and not {cpu,runtime}? If it's the
latter, I'm not sure I follow. If it's the former, sorry for the noise!

The case I'm worried about is a set of task-bound events that have CPU
filters. For example, if the user opens a set of task-bound events for
any CPU:

perf_event_open(attr1, pid, -1, -1, 0);
perf_event_open(attr2, pid, -1, -1, 0);

... and also some for the same task, but limited to a specific CPU:

perf_event_open(attr3, pid, 1, -1, 0);
perf_event_open(attr4, pid, 1, -1, 0);

... if CPU is before runtime in the sort, one of these groups will
always be considered first when scheduling, and may starve the other
group.

Today, the rotation gives us some degree of fairness here that we would
lose.

Sure. However, I think a similar issue to the above applies when
scheduling events where some are bound to a specific cgroup, and others
are not.

Oh Sorry, my bad. My brain must not be working yesterday...
I just re-visited the code. The *inactive* also need to be checked.
	if (event->state < PERF_EVENT_STATE_INACTIVE)
		continue;
So the perf_iterate_sb iterates through all events (both STATE_ACTIVE
and STATE_INACTIVE).

I'm not sure if it is enough to only take care of *active* events.
Peter may comments on it.

On second thought, I think the pmu pointer or id can be retrieved from
the event since the tree key only needs to be calculated when an event
is to be inserted.

Also, if there is no real need for an timestamp and or runtime, and it's enough
to keep insertion order (so rotation occurs naturally). Then the rb-tree could
be simplified to only contain either {cpu,pmu,flexible} or {cgroup,flexible} in
its key and each node in the tree would be a sorted list of events.

In this series, the only search operations I do in the rb-tree are
"find first event
and "find last event" in each {cpu,pmu,flexible}/{cgroup,flexible} group. This
could be done faster with a list and we'd save the tree rebalancing.

Yes, that case is the reason to have the sorted inactive_list and
 the tree. I tried to explain this in the change log of this patch. Please

Yes, it's addressed in the same way.


For both task and cpu contexts the idea is the same. It is:

1. For each "group" of events (either pmu/cpu or cgroup/NULL)
that is eligible to sched_in  in current cpu/cgroup, find the pair of
minimum and
maximum events in timestamp order, using the rb-tree.
2. Each (min,max) pair is an interval in the ctx->inactive_groups list
(list is sorted by
timestamp only).
3. Merge all those min/maxs for all eligible cpus/cgroups and obtain
an overall (min,max).
That's the interval in the ctx->inactive_groups to use by ctx_sched_in.

The overall interval of events may contain ineligible events (i.e.
events bound to a
a  CPU or cgroup that cannot be sched in), but that's ok because:
    a) events are filtered using event_filter_match anyways and,
    b) since events are sorted by timestamp, events that not passed
the filter move behind
    in the list in each ctx switch in/out cycle. All ineligible events
are left behind after a few
    cycles of ctx sw in/out. This work in amortized linear time for
the worst case. The worst
    case occurs after a CPU/cgroup change. The stationary case is optimal.

The patch 6/6 in this series is the one that changes perf_iterate and
does iterate over active and
inactive events, so it only skips events in OFF and ERROR state.

That's mostly a reading comprehension failure on my behalf, the commit
log does accurately describe this. It might be a little clearer if we
say the inactive list is sorted *solely* by timestamp, but nothing more
than that should be necessary.

Sure, that's not clear to me either.

Even with that, there's the risk that one CPU is blocked for a period
wiating for those few others to respond to IPIs. But as you say, it's
not obviously a problem in practice today.

Given it's of minor/unknown benefit, and would complicate this series,
feel free to forget about it. I'll add it to the list of things to clean
up at some point in future. ;)

For the *sched_in path, yes.

If we could handle dynamic contexts, I'd try to get rid of the context
type entirely, and have a flag on the PMU to describe that it was a pure
SW PMU.

I hadn't realised that was the case. That'll violate one of the main
invariants regarding SW events, so we've probably got additional subtle
breakage there (e.g. SW elligible events not being scheduled).

In general, I would expect a small number. 

One or two CPU PMUs is the likely case today, but we could see more in
future, and tracing PMUs will add to that (those can differ across
microarchitectures, too). I can imagine seeing at least four in the near
term.

Maybe. Bumping perf_nr_task_contexts, and dynamically allocating the
pmu::task_ctx_nr for HW PMUs would give some relief.

Thanks,

RE: [RFC 0/6] optimize ctx switch with rb-tree

[Liang, Kan]

Is there any update about the patch series?

We recently encountered another performance issue on KNL. I think the RB-tree solution also has benefits for it.

Thanks,
Kan

Re: [RFC 0/6] optimize ctx switch with rb-tree

[David Carrillo-Cisneros]

Hi Kan,

It's still on my list, but I won't have time to work on it for at
least another month.

What issues did you encounter?

Thanks,
David

RE: [RFC 0/6] optimize ctx switch with rb-tree

[Budankov, Alexey]

Hi David,

I profiled single threaded STREAM benchmark pinned to core #1 on KNL machine with kernel 3.10.0-327.13.1.el7.x86_64 (from MPSS distribution). I run the system-wide and the per-process profiling for the same list of events and got ~5x slowdown for the per-process scenario. 
Simultaneously I was collecting ftrace logs for the both cases and found that there is huge slowdown in handling of multiplexing timer interrupt for the per-process case in comparison to the system-wide one:

I looked at the source code and see that in the per-process case the whole list of allocated events (29 x 272) is traversed twice on every timer interrupt during that 2ms and 600us intervals. However the only 29 per-cpu events are iterated in the system-wide case:

kernel/events/core.c:2799:

static void ctx_sched_out(struct perf_event_context *ctx,
              struct perf_cpu_context *cpuctx,
              enum event_type_t event_type)
{
#ifdef PERF___ENABLE_CTX_ROT
    struct perf_event *event;
    int is_active = ctx->is_active;
#endif

    ctx->is_active &= ~event_type;
    if (likely(!ctx->nr_events))
        return;

    update_context_time(ctx);
    update_cgrp_time_from_cpuctx(cpuctx);
    if (!ctx->nr_active)
        return;

    perf_pmu_disable(ctx->pmu);
#ifdef PERF___ENABLE_CTX_ROT
    if ((is_active & EVENT_PINNED) && (event_type & EVENT_PINNED)) {
        list_for_each_entry(event, &ctx->pinned_groups, group_entry)
            group_sched_out(event, cpuctx, ctx);
    }

    if ((is_active & EVENT_FLEXIBLE) && (event_type & EVENT_FLEXIBLE)) {
        list_for_each_entry(event, &ctx->flexible_groups, group_entry)
            group_sched_out(event, cpuctx, ctx);
    }
#endif
    perf_pmu_enable(ctx->pmu);
}

kernel/events/core.c:2384

static void
ctx_sched_in(struct perf_event_context *ctx,
         struct perf_cpu_context *cpuctx,
         enum event_type_t event_type,
         struct task_struct *task)
{
    u64 now;
#ifdef PERF___ENABLE_CTX_ROT
    int is_active = ctx->is_active;
    ctx->is_active |= event_type;
#endif
    if (likely(!ctx->nr_events))
        return;

    now = perf_clock();
    ctx->timestamp = now;
    perf_cgroup_set_timestamp(task, ctx);
    /*
     * First go through the list and put on any pinned groups
     * in order to give them the best chance of going on.
     */
#ifdef PERF___ENABLE_CTX_ROT
    if (!(is_active & EVENT_PINNED) && (event_type & EVENT_PINNED))
        ctx_pinned_sched_in(ctx, cpuctx);

    /* Then walk through the lower prio flexible groups */
    if (!(is_active & EVENT_FLEXIBLE) && (event_type & EVENT_FLEXIBLE))
        ctx_flexible_sched_in(ctx, cpuctx);
#endif
}

If I disable traversing in the per-process case then the overhead disappears.

For the system-wide case the ctx->pinned_groups and ctx->flexible_groups lists are parts of per-cpu perf_cpu_context object and count of iterations is small (#events == 29).

Thanks,
Alexey

Yes, seems like it would benefit from the rb-tree optimization.

Something that is wrong in my RFC (as Mark notes in the "enjoyment"
section of  https://lkml.org/lkml/2017/1/12/254), is that care must be
taken to disable the right pmu when dealing with contexts that have
events from more than one PMU. A way to do it is to have the pmu as
part of the rb-tree key (as Peter initially suggested) and use that to
iterate events in the same pmu together.

There's still the open question of what to do when pmu->add fails.
Currently, it stops scheduling events, but that's not right when
dealing with events in "software context" that are not software events
(I am looking at you CQM) and in hardware contexts with more than one
PMU (ARM big-little). Ideally a change in event scheduler should
address that, but it requires more work. Here is a discussion with
Peter about that (https://lkml.org/lkml/2017/1/25/365).

If you guys want to work on it, I'll be happy to help review.
Otherwise, I'll get to it as soon as I have a chance (1-2 months).

Thanks,
David

Sounds good.

> Could you provide me with the cumulative patch set to expedite the ramp up?

This RFC is my latest version. I did not have a good solution on how
to solve the problem of handling failure of PMUs that share contexts,
and to activate/inactivate them.

Some things to keep in mind when dealing with task-contexts are:
  1. The number of PMUs is large and growing, iterating over all PMUs
may be expensive (see https://lkml.org/lkml/2017/1/18/859 ).
  2. event_filter_match in this RFC is only used because I did not
find a better ways to filter out events with the rb-tree. It would be
nice if we wouldn't have to check event->cpu != -1 && event->cpu ==
smp_processor_id() and cgroup stuff for every event in task contexts.
  3. I used the inactive events list in this RFC as a cheaper
alternative to threading the rb-tree but it has the problem that
events that are removed due to conflict would be placed at the end of
the list even if didn't run. I cannot recall if that ever happens.
Using this list also causes problem (2.) maybe threading the tree is a
better alternative?
  4. Making the key in task-events to be {PMU,CPU,last_time_scheduled}
(as opposed to {CPU,last_time_scheduled} in the RFC) may simplify
sched in by helping to iterate over all events in same PMU at once,
simplifying the activation/inactivation of the PMU and making it
simple to move to the next PMU on pmu::add errors. The problem with
this approach is to find only the PMUs with inactive events without
traversing a list of all PMUs. Maybe a per-context list of active PMUs
may help (see 1.).

cpu-contexts are much simpler and I think work well with what the RFC
does (they are per-pmu already).

This thread has Peter and Mark's original discussion of the rb-tree
(https://patchwork.kernel.org/patch/9176121/).
