From: Peter Zijlstra <peterz@infradead.org>
This is the 2nd version of RFC originally posted by Peter[1].
There have been various issues and limitations with the way perf uses
(task) contexts to track events. Most notable is the single hardware
PMU task context, which has resulted in a number of yucky things (both
proposed and merged).
Notably:
- HW breakpoint PMU
- ARM big.little PMU / Intel ADL PMU
- Intel Branch Monitoring PMU
- AMD IBS
Current design:
---------------
Currently we have a per task and per cpu perf_event_contexts:
task_struct::perf_events_ctxp[] <-> perf_event_context <-> perf_cpu_context
^ | ^ |
`---------------------------------' | `--> pmu
v ^
perf_event ------'
Each task has an array of pointers to a perf_event_context. Each
perf_event_context has a direct relation to a PMU and a group of
events for that PMU. The task related perf_event_context's have a
pointer back to that task.
Each PMU has a per-cpu pointer to a per-cpu perf_cpu_context, which
includes a perf_event_context, which again has a direct relation to
that PMU, and a group of events for that PMU.
The perf_cpu_context also tracks which task context is currently
associated with that CPU and includes a few other things like the
hrtimer for rotation etc.
Each perf_event is then associated with its PMU and one
perf_event_context.
Proposed design:
----------------
New design proposed by this patch reduce to a single task context and
a single CPU context but adds some intermediate data-structures:
task_struct::perf_event_ctxp -> perf_event_context <- perf_cpu_context
^ | ^ ^
`---------------------------------' | |
| | perf_cpu_pmu_context
| `----. ^
| | |
| v v
| ,--> perf_event_pmu_context
| | ^
| | |
v v v
perf_event ---> pmu
With new design, perf_event_context will hold all pmu events in the
respective(pinned/flexible) rbtrees. This can be achieved by adding
pmu to rbtree key:
{cpu, pmu, cgroup_id, group_index}
Each perf_event_context carry a list of perf_event_pmu_context which
is used to hold per-pmu-per-context state. For ex, it keeps track of
currently active events for that pmu, a pmu specific task_ctx_data,
a flag to tell whether rotation is required or not etc.
Similarly perf_cpu_pmu_context is used to hold per-pmu-per-cpu state
like hrtimer details to drive the event rotation, a pointer to
perf_event_pmu_context of currently running task and some other
ancillary information.
Each perf_event is associated to it's pmu, perf_event_context and
perf_event_pmu_context.
Original RFC -> RFC v2:
-----------------------
In addition to porting the patch to latest (v5.16-rc6) kernel, here
are some of the major changes between two revisions:
- There were quite a bit of fundamental changes since original patch.
Most notably a rbtree key has changed from {cpu,group_index} to
{cpu,cgroup_id,group_index}. Adding a pmu key in between as proposed
in original patch is not straight forward as it will break cgroup
specific optimization. Hence we need to iterate over all pmu_ctx
for a given ctx and call visit_groups_merge() one by one.
- Enabled cgroup support (CGROUP_PERF).
- Some changes wrt multiplexing events as with new design the rotation
happens at cgroup subtree unlike at pmu subtree in original patch.
Because of additional complexity above changes bring in, I thought to
get initial review about the overall approach before starting to make it
upstream ready. Hence this patch just provides an idea of the direction
we will head toward. Many loose ends in the patch rightnow. Like, I've
not paid much attention to synchronization related aspects. Similarly,
some of the issues marked in original patch (XXX) haven't been fixed.
A simple perf stat/record/top survives with the patch but machine
crashes with first run of perf test (stale cpc->task_epc causing the
crash). Lockdep is also screaming a lot :)

pulling up the ctx->mutex makes things simpler, but also violates the
locking order vs exec_update_lock.
Pull that lock up as well...

I think we need to keep (ctx->task == TASK_TOMBSTONE) check?

I was just about to rebase the 'series' to current, let me do that and
get back to you on the specifics.

With this, I can run 'perf test' and perf_event_tests without any error in

I was able to reproduce this with vanilla v6.0-rc2 kernel.

Right; clearly I didn't even test build that thing... your changes look
fine and added then on top, above tree should be updated.

I also ran fuzzer on Intel machine over the weekend. I see only one WARN_ON()
hit. Otherwise system is running normal. FWIW, I was running fuzzer as normal
user with perf_event_paranoid=0.

That's the WARN about PERF_HES_STOPPED already being set.

And this callchain suggests this is the group_error path.
I can't immediately spot a fail there, but I'll try and stare at it
some.

I think so too; in fact the code I have still has it, perhaps it was

Idem.
Perhaps it is best if we look at the end result of all these patches
combined and then I'll fold the lot if we're in agreement and then we
can forget about these intermediate steps.

Let me accumulate all these changes, rebase to v6.0-rc2 and send RFC v3.

You mentioned trouble with cpc->task_epc, there's one rebase mistake
from you and an original bug from me.
You lost the last hunk, I forgot to clear cpc on
perf_remove_from_context().
With these fixes I can run: 'perf test' without things going
insta-splat.

I'm not sure I follow.. task context can have multiple PMUs just the
same as CPU context can, that's more or less the entire point of the
patch.

Current rbtree key is {cpu, cgroup_id, group_idx}. However, effective key for
task specific context is {cpu, group_idx} because cgroup_id is always 0. And
effective key for cpu specific context is {cgroup_id, group_idx} because cpu
is same for entire rbtree.
With New design, rbtree key will be {cpu, pmu, cgroup_id, group_idx}. But as
explained above, effective key for task specific context will be {cpu, pmu,
group_idx}. Thus, we can handle pmu=NULL in visit_groups_merge(), same as you
did in the very first RFC[1]. (This may make things more complicated though
because we might also need to increase heap size to accommodate all pmu events
in single heap. Current heap size is 2 for task specific context, which is
sufficient if we iterate over all pmus).
Same optimization won't work for cpu specific context because, it's effective
key would be {pmu, cgroup_id, group_idx} i.e. each pmu subtree is made up of
cgroup subtrees.
Please correct me if my understanding is wrong.
Thanks,
Ravi

Agreed, new order is: {cpu, pmu, cgroup_id, group_idx}
Event scheduling looks at the {cpu, pmu, cgroup_id} subtree to find the
leftmost group_idx event to schedule next.
However, since cgroup events are per-cpu events, per-task events will
always have cgroup=NULL. Resulting in the subtrees:
{-1, pmu, NULL} and {cpu, pmu, NULL}
Which is what the code does, it iterates ctx->pmu_ctx_list to find all
@pmu values and then for each does the schedule dance.
Now, I suppose making that:
{-1, NULL, NULL}, {cpu, NULL, NULL}
could work, but wouldn't iterating the the tree be more expensive than
just finding the sub-trees as we do now?
You also talk about extending extending the heap, which I read like
doing the heap-merge over:
{-1, pmu0, NULL}, {-1, pmu1, NULL}, ...
{cpu, pmu0, NULL}, ...
But that doesn't make sense, the schedule dance is per-pmu.
Or am I just still not getting it?

pmu=NULL can be used while scheduling entire context. We can just traverse
through all pmu events of both cpu subtrees.

Ok. Let's not complicate the design. We can go with current approach of
iterating over all pmus in the first phase and think about optimizing it
later.

But imagine the case where we have 50 event for a PMU that can only
schedule 8. Then we have to iterate 42 events for naught instead of
directly jumping to the next PMU.

Yes, that needs to be handled. And, IIRC, you proposed maintaining a list
of leftmost event from each pmu subtree.

No; this really should be against the event's native PMU. If the event
can't natively sample, it can't sample when placed in another group
either.

Right. But IIUC, the question was, would there be any issue if we allow
grouping of perf_sw_context sampling event as group leader and
perf_{hw|invalid}_context counting event as group member. I think no. It
should just work fine. And, there could be real usecases of it as you
described in one old thread[1].
TL;DR
Although I can't find any such pmu combination on AMD(not considering real
sw pmus), I just tried opposite scenario:
Group leader: msr/tsc/ as counting event (perf_sw_context)
Group member: ibs_op/cnt_ctl=1/ as sampling event (perf_invalid_context)
And a simple test program seems to work fine:

Like you I need to bend my brain around this again, but I'm not seeing a
contradiction. The use-case from [1] is a software sampler with a bunch
of non-sampling uncore events.
The uncore events aren't sampling, the are simply read by the software
event (SAMPLE_READ). And moving the sampling software event to the
non-sample capable uncore PMU shouldn't matter.
That is; the code as it stands here seems right, we should check
is_sampling_event() against an event's native pmu->capabilities.
Or am I misunderstanding things?

No, that's correct. We must use event's native pmu to check capabilities.
I'll remove this comment from code.

Thanks! I've resumed on this but my mind has lost all the context so
it might take a while for me to reply to your comments. Please bear
with me if I'm bit slow.
Thanks,

Sorry, it took a while for me to get started on it. Anyways, thanks for
providing fixes. I applied those and ran some tests on AMD Milan machine:
- Built in perf tests ran fine without any issues
- perf_event_tests reported one BUG_ON() and one WARN_ON(). I'll work on
fixing those.
- Ran perf fuzzer for almost a day. It reported one softlockup but system
recovered from it and later it reported one hardlockup but unfortunately
my config had HARDLOCKUP_PANIC set and thus couldn't confirm whether that
hardlockup was recoverable or not. Anyway, system was running pretty much
fine until then.
- No lockdep warnings were observed in any of the tests.
I'll work on verifying functionality changes.
Thanks,
Ravi

There are many callers of event_filter_match() which might not endup calling
visit_groups_merge(). I hope this is intentional change?

I thought I did, but lets go through them again.
event_filter_match() is called from:
- __perf_event_enable(); here we'll end up in ctx_sched_in() which
will dutifully skip the pmu in question.
(fwiw, this is one of those sites where ctx_sched_{out,in}() could do
with a @pmu argument.
- merge_sched_in(); this is after the new callsite in
visit_groups_merge().
- perf_adjust_freq_unthrottle_context(); if the pmu was skipped in
visit_groups_merge() then ->state != ACTIVE and we'll bail out.
- perf_iterate_ctx() / perf_iterate_sb_cpu(); these are for generating
side-band events, and arguably not delivering them when running on
the 'wrong' CPU wasn't right to begin with.
So I tihnk we're good. Hmm?

While collating this I came across armv8pmu_start() which does:
struct perf_event_context *task_ctx =
this_cpu_ptr(cpu_pmu->pmu.pmu_cpu_context)->task_ctx;
if (sysctl_perf_user_access && task_ctx && task_ctx->nr_user)
Not sure why it does not lock task_ctx. Should it be changed to
something like below? Untested:

ctx_resched() reschedule entire perf_event_context while adding new event
to the context or enabling existing event in the context. We can probably
optimize it by rescheduling only affected pmu_ctx.

Yes, it would probably make sense to add a pmu argument there and limit
the rescheduling where possible.

Also, this hunk is under if (is_active ^ EVENT_TIME), which effectively is
(is_active != EVENT_TIME). I'm assuming it should be (is_active & EVENT_TIME)?

No memories at all; but looking at it; it seems to worry if ctx->task is
up-to-date; in this context the only thing that relies on the task is
the cgroup for which we update the timestamp in the next statement:

I suppose I should really write less cryptic notes; then again, I never
imagined this would take that many years to complete :/

So that code is identical to what it currently is upstream; but yes that
looks somewhat dodgy.
So the code itself (does as the comment says) starts time. This should
only be done if EVENT_TIME is not set. That is, I'm thinking it should
be something like:
!(is_active & EVENT_TIME)
which happens to be the same as:
is_active ^ EVENT_TIME
under the assumption is_active contains no other bits -- which I don't
think is a valid assumption.

Got it.

Does that mean context time should be started only when context is getting
scheduled I.e. ctx->is_active is 0 ?

Correct, we can't assume that. There are cases where we call
ctx_sched_out(EVENT_TIME) followed by ctx_sched_in(EVENT_TIME) when PINNED /
FLEXIBLE are also set in ctx->is_active. For ex, perf_event_enable_on_exec().
In such cases, we will not advance ctx->time. Example:
child()
{
...
execv();
}
main()
{
pid = fork();
attr.enable_on_exec = 0;
fd0 = perf_event_open(&attr, pid, -1, -1, 0);
...
wait(NULL);
}
Here execv() will cause call to ctx_sched_in() --> __update_context_time()
with adv=false. I think that's fine. Sometime later we will anyway advance
ctx->time.
Sorry, I've not spend enough time with this time keeping code. Please let
me know if I'm talking nonsense.
Thanks,
Ravi

This should be fixed as well:
