It would be useful to support the overall statistics for perf-stat
interval mode. For example, report the summary at the end of
"perf-stat -I" output.
But since perf-stat can support many aggregation modes, such as
--per-thread, --per-socket, -M and etc, we need a solution which
doesn't bring much
root@kbl-ppc:~# perf stat --per-thread -e cycles,instructions -I1000
--interval-count 2
1.004171683 perf-3696 8,747,311 cycles

A small question here:
Is this clock critical for the whole system or only for HDMIMIX?
What if HDMIIX is no
Currently perf-stat supports to print counts at regular interval (-I),
but it's not very easy for user to get the overall statistics.
The patch uses 'evsel->prev_raw_counts' to get counts for summary.
Copy the counts to 'evsel->counts' after printing the interval results.
Next, we just follow the
The evsel->prev_raw_counts is updated in perf_evsel__compute_deltas:
perf_evsel__compute_deltas()
{
tmp = *perf_counts(evsel->prev_raw_counts, cpu, thread);
*perf_counts(evsel->prev_raw_counts, cpu, thread) = *count;
}
When we want to reset the evsel->prev_raw_counts in

Currently perf-stat supports to print counts at regular interval (-I),
but it's not very easy for user to get the overall statistics.
With this patchset, it supports to report the summary at the end of
interval output.
For example,

When we fill up a receive VQ, try_fill_recv currently tries to count
kicks using a 64 bit stats counter. Turns out, on a 32 bit kernel that
uses a seqcount. sequence counts are "lock" constructs where you need to
make sure that writers are serialized.
In turn, this means that we mustn't run two tr

There are already firmware API commands that have multiple
versions. For each multiple version command, another command
to retrieve the API version is issued. This may introduce an important
overhead. The version does not change while the system is running,
so the DPRC API version can be safely cac
Prepare the dprc_scan_objects function to be used by
the VFIO mc driver code. The function is used to scan the mc
objects by the bus driver. The same functionality is
needed by the VFIO mc driver, but in this case the
interrupt configuration is delayed until the userspace
configures the interrupts.
Both DPRC driver and VFIO driver use the same initialization
code for the DPRC. Introduced a new function which groups this
initialization code. The function is exported and may be
used by VFIO as well.

In this case wouldn't it be better to backport a change that disables
the specific compiler warning?

The dll-user-control register need to be configured during dll

Without this configuration, we don't get the DLL lock status properly.

If a metric contains the duration_time event then the event is placed
outside of the metric's group of events. Rather than split the group,
make it so the duration_time is immediately after the group.

A metric group contains multiple metrics. These metrics may use the same
events. If metrics use separate events then it leads to more
multiplexing and overall metric counts fail to sum to 100%.
Modify how metrics are associated with events so that if the events in
an earlier group satisfy the curre
Metric groups contain metrics. Metrics create groups of events to
ideally be scheduled together. Often metrics refer to the same events,
for example, a cache hit and cache miss rate. Using separate event
groups means these metrics are multiplexed at different times and the
counts don't sum to 100%.

When adding event groups to the group list, insert them in size order.
This performs an insertion sort on the group list. By placing the
largest groups at the front of the group list it is possible to see if a

Currently event groups are placed into groups_list at the same time as

Use a hashmap between a char* string and a double* value. While bpf's
hashmap entries are size_t in size, we can't guarantee sizeof(size_t) >=
sizeof(double). Avoid a memory allocation when gathering ids by making 0.0
a special value encoded as NULL.
