In the system-wide mode, LBR callstacks are shorter in comparison to
the per-process mode.
LBR MSRs are reset during a context switch in the system-wide mode. For
the LBR call stack, the LBRs should be always saved/restored during a
context switch.
Use the space in task_struct to save/restore the LBR call stack data.
For a system-wide event, it's unnecessagy to update the
lbr_callstack_users for each threads. Add a variable in x86_pmu to
indicate whether the system-wide event is active.

The LBR call stack data has to be saved/restored during context switch
to fix the shorter LBRs call stacks issue in the system-wide mode.
Allocate PMU specific data and attach them to the corresponding
task_struct during LBR call stack monitoring.
When a LBR call stack event is accounted, the perf_ctx_data for the
related tasks will be allocated/attached by attach_perf_ctx_data().
When a LBR call stack event is unaccounted, the perf_ctx_data for
related tasks will be detached/freed by detach_perf_ctx_data().
The LBR call stack event could be a per-task event or a system-wide
event.
- For a per-task event, perf only allocates the perf_ctx_data for the
current task. If the allocation fails, perf will error out.
- For a system-wide event, perf has to allocate the perf_ctx_data for
both the existing tasks and the upcoming tasks.
The allocation for the existing tasks is done in perf_event_alloc().
If any allocation fails, perf will error out.
The allocation for the new tasks will be done in perf_event_fork().
A global reader/writer semaphore, global_ctx_data_rwsem, is added to
address the global race.
- The perf_ctx_data only be freed by the last LBR call stack event.
The number of the per-task events is tracked by refcount of each task.
Since the system-wide events impact all tasks, it's not practical to
go through the whole task list to update the refcount for each
system-wide event. The number of system-wide events is tracked by a
global variable global_ctx_data_ref.

Some PMU specific data has to be saved/restored during context switch,
e.g. LBR call stack data. Currently, the data is saved in event context
structure, but only for per-process event. For system-wide event,
because of missing the LBR call stack data after context switch, LBR
callstacks are always shorter in comparison to per-process mode.
For example,
Per-process mode:
$perf record --call-graph lbr -- taskset -c 0 ./tchain_edit
- 99.90% 99.86% tchain_edit tchain_edit [.] f3
99.86% _start
__libc_start_main
generic_start_main
main
f1
- f2
f3
System-wide mode:
$perf record --call-graph lbr -a -- taskset -c 0 ./tchain_edit
- 99.88% 99.82% tchain_edit tchain_edit [.] f3
- 62.02% main
f1
f2
f3
- 28.83% f1
- f2
f3
- 28.83% f1
- f2
f3
- 8.88% generic_start_main
main
f1
f2
f3
It isn't practical to simply allocate the data for system-wide event in
CPU context structure for all tasks. We have no idea which CPU a task
will be scheduled to. The duplicated LBR data has to be maintained on
every CPU context structure. That's a huge waste. Otherwise, the LBR
data still lost if the task is scheduled to another CPU.
Save the pmu specific data in task_struct. The size of pmu specific data
is 788 bytes for LBR call stack. Usually, the overall amount of threads
doesn't exceed a few thousands. For 10K threads, keeping LBR data would
consume additional ~8MB. The additional space will only be allocated
during LBR call stack monitoring. It will be released when the
monitoring is finished.
Furthermore, moving task_ctx_data from perf_event_context to task_struct
can reduce complexity and make things clearer. E.g. perf doesn't need to
swap task_ctx_data on optimized context switch path.
This patch set is just the first step. There could be other
optimization/extension on top of this patch set. E.g. for cgroup
profiling, perf just needs to save/store the LBR call stack information
for tasks in specific cgroup. That could reduce the additional space.
Also, the LBR call stack can be available for software events, or allow
even debugging use cases, like LBRs on crash later.
Because of the alignment requirement of Intel Arch LBR, the Kmem cache
is used to allocate the PMU specific data. It's required when child task
allocates the space. Save it in struct perf_ctx_data.
The refcount in struct perf_ctx_data is used to track the users of pmu
specific data.

The commit 97c79a38cd ("perf core: Per event callchain limit")
introduced a per-event term to allow finer tuning of the depth of
callchains to save space.
It should be applied to the branch stack as well. For example, autoFDO
collections require maximum LBR entries. In the meantime, other
system-wide LBR users may only be interested in the latest a few number
of LBRs. A per-event LBR depth would save the perf output buffer.
The patch simply drops the uninterested branches, but HW still collects
the maximum branches. There may be a model-specific optimization that
can reduce the HW depth for some cases to reduce the overhead further.
But it isn't included in the patch set. Because it's not useful for all
cases. For example, ARCH LBR can utilize the PEBS and XSAVE to collect
LBRs. The depth should have less impact on the collecting overhead.
The model-specific optimization may be implemented later separately.
