perf tools changes for v5.10: 1st batch

Browse Source 
- cgroup improvements for 'perf stat', allowing for compact specification of events
   and cgroups in the command line.
 
 - Support per thread topdown metrics in 'perf stat'.
 
 - Support sample-read topdown metric group in 'perf record'
 
 - Show start of latency in addition to its start in 'perf sched latency'.

   modifier.
 
 - Add 'snapshot' command to 'perf record --control', using it with Intel PT.
 
 - Support FIFO file names as alternative options to 'perf record --control'.
 
 - Introduce branch history "streams", to compare 'perf record' runs with
   'perf diff' based on branch records and report hot streams.
 
 - Support PE executable symbol tables using libbfd, to profile, for instance, wine binaries.
 
 - Add filter support for option 'perf ftrace -F/--funcs'.
 
 - Allow configuring the 'disassembler_style' 'perf annotate' knob via 'perf config'
 
 - Update CascadelakeX and SkylakeX JSON vendor events files.
 
 - Add support for parsing perchip/percore JSON vendor events.
 
 - Add power9 hv_24x7 core level metric events.
 
 - Add L2 prefetch, ITLB instruction fetch hits JSON events for AMD zen1.
 
 - Enable Family 19h users by matching Zen2 AMD vendor events.
 
 - Use debuginfod in 'perf probe' when required debug files not found locally.
 
 - Display negative tid in non-sample events in 'perf script'.
 
 - Make GTK2 support opt-in
 
 - Add build test with GTK+
 
 - Add missing -lzstd to the fast path feature detection

 - Fix JSON event code for events referencing std arch events.
 
 - Introduce 'perf test' shell script for Arm CoreSight testing.
 
 - Add rdtsc() for Arm64 for used in the PERF_RECORD_TIME_CONV metadata
   event and in 'perf test tsc'.
 
 - 'perf c2c' improvements: Add "RMT Load Hit" metric, "Total Stores", fixes
   and documentation update.
 
 - Fix usage of reloc_sym in 'perf probe' when using both kallsyms and debuginfo files.
 
 - Do not print 'Metric Groups:' unnecessarily in 'perf list'
 
 - Refcounting fixes in the event parsing code.
 
 - Add expand cgroup event 'perf test' entry.
 
 - Fix out of bounds CPU map access when handling armv8_pmu events in 'perf stat'.
 
 - Add build-id injection 'perf bench' benchmark.
 
 - Enter namespace when reading build-id in 'perf inject'.
 
 - Do not load map/dso when injecting build-id speeding up the 'perf inject' process.
 
 - Add --buildid-all option to avoid processing all samples, just the mmap metadata events.
 
 - Add feature test to check if libbfd has buildid support
 
 - Add 'perf test' entry for PE binary format support.

 Test results:
 
 The first ones are container based builds of tools/perf with and without libelf
 support.  Where clang is available, it is also used to build perf with/without
 libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
 when clang and its devel libraries are installed.
 
 The objtool and samples/bpf/ builds are disabled now that I'm switching from
 using the sources in a local volume to fetching them from a http server to
 build it inside the container, to make it easier to build in a container cluster.
 Those will come back later.
 
 Several are cross builds, the ones with -x-ARCH and the android one, and those
 may not have all the features built, due to lack of multi-arch devel packages,
 available and being used so far on just a few, like
 debian:experimental-x-{arm64,mipsel}.
 
 The 'perf test' one will perform a variety of tests exercising
 tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
 with a variety of command line event specifications to then intercept the
 sys_perf_event syscall to check that the perf_event_attr fields are set up as
 expected, among a variety of other unit tests.
 
 Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
 with a variety of feature sets, exercising the build with an incomplete set of
 features as well as with a complete one. It is planned to have it run on each
 of the containers mentioned above, using some container orchestration
 infrastructure. Get in contact if interested in helping having this in place.

Merge tag 'perf-tools-for-v5.10-2020-10-15' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tools updates from Arnaldo Carvalho de Melo:

 - cgroup improvements for 'perf stat', allowing for compact
   specification of events and cgroups in the command line.

 - Support per thread topdown metrics in 'perf stat'.

 - Support sample-read topdown metric group in 'perf record'

 - Show start of latency in addition to its start in 'perf sched
   latency'.

 - Add min, max to 'perf script' futex-contention output, in addition to
   avg.

 - Allow usage of 'perf_event_attr->exclusive' attribute via the new
   ':e' event modifier.

 - Add 'snapshot' command to 'perf record --control', using it with
   Intel PT.

 - Support FIFO file names as alternative options to 'perf record
   --control'.

 - Introduce branch history "streams", to compare 'perf record' runs
   with 'perf diff' based on branch records and report hot streams.

 - Support PE executable symbol tables using libbfd, to profile, for
   instance, wine binaries.

 - Add filter support for option 'perf ftrace -F/--funcs'.

 - Allow configuring the 'disassembler_style' 'perf annotate' knob via
   'perf config'

 - Update CascadelakeX and SkylakeX JSON vendor events files.

 - Add support for parsing perchip/percore JSON vendor events.

 - Add power9 hv_24x7 core level metric events.

 - Add L2 prefetch, ITLB instruction fetch hits JSON events for AMD
   zen1.

 - Enable Family 19h users by matching Zen2 AMD vendor events.

 - Use debuginfod in 'perf probe' when required debug files not found
   locally.

 - Display negative tid in non-sample events in 'perf script'.

 - Make GTK2 support opt-in

 - Add build test with GTK+

 - Add missing -lzstd to the fast path feature detection

 - Add scripts to auto generate 'mmap', 'mremap' string<->id tables for
   use in 'perf trace'.

 - Show python test script in verbose mode.

 - Fix uncore metric expressions

 - Msan uninitialized use fixes.

 - Use condition variables in 'perf bench numa'

 - Autodetect python3 binary in systems without python2.

 - Support md5 build ids in addition to sha1.

 - Add build id 'perf test' regression test.

 - Fix printable strings in python3 scripts.

 - Fix off by ones in 'perf trace' in arches using libaudit.

 - Fix JSON event code for events referencing std arch events.

 - Introduce 'perf test' shell script for Arm CoreSight testing.

 - Add rdtsc() for Arm64 for used in the PERF_RECORD_TIME_CONV metadata
   event and in 'perf test tsc'.

 - 'perf c2c' improvements: Add "RMT Load Hit" metric, "Total Stores",
   fixes and documentation update.

 - Fix usage of reloc_sym in 'perf probe' when using both kallsyms and
   debuginfo files.

 - Do not print 'Metric Groups:' unnecessarily in 'perf list'

 - Refcounting fixes in the event parsing code.

 - Add expand cgroup event 'perf test' entry.

 - Fix out of bounds CPU map access when handling armv8_pmu events in
   'perf stat'.

 - Add build-id injection 'perf bench' benchmark.

 - Enter namespace when reading build-id in 'perf inject'.

 - Do not load map/dso when injecting build-id speeding up the 'perf
   inject' process.

 - Add --buildid-all option to avoid processing all samples, just the
   mmap metadata events.

 - Add feature test to check if libbfd has buildid support

 - Add 'perf test' entry for PE binary format support.

 - Fix typos in power8 PMU vendor events JSON files.

 - Hide libtraceevent non API functions.

Using TopDown metrics in user space
-----------------------------------
Intel CPUs (since Sandy Bridge and Silvermont) support a TopDown
methology to break down CPU pipeline execution into 4 bottlenecks:
frontend bound, backend bound, bad speculation, retiring.
For more details on Topdown see [1][5]
Traditionally this was implemented by events in generic counters
and specific formulas to compute the bottlenecks.
perf stat --topdown implements this.
Full Top Down includes more levels that can break down the
bottlenecks further. This is not directly implemented in perf,
but available in other tools that can run on top of perf,
such as toplev[2] or vtune[3]
New Topdown features in Ice Lake
===============================
With Ice Lake CPUs the TopDown metrics are directly available as
fixed counters and do not require generic counters. This allows
to collect TopDown always in addition to other events.
% perf stat -a --topdown -I1000
# time retiring bad speculation frontend bound backend bound
1.001281330 23.0% 15.3% 29.6% 32.1%
2.003009005 5.0% 6.8% 46.6% 41.6%
3.004646182 6.7% 6.7% 46.0% 40.6%
4.006326375 5.0% 6.4% 47.6% 41.0%
5.007991804 5.1% 6.3% 46.3% 42.3%

8.012951831 4.7% 6.7% 47.5% 41.1%
...
This also enables measuring TopDown per thread/process instead
of only per core.
Using TopDown through RDPMC in applications on Ice Lake
======================================================
For more fine grained measurements it can be useful to
access the new directly from user space. This is more complicated,
but drastically lowers overhead.
On Ice Lake, there is a new fixed counter 3: SLOTS, which reports
"pipeline SLOTS" (cycles multiplied by core issue width) and a
metric register that reports slots ratios for the different bottleneck
categories.
The metrics counter is CPU model specific and is not available on older
CPUs.
Example code
============
Library functions to do the functionality described below
is also available in libjevents [4]
The application opens a group with fixed counter 3 (SLOTS) and any
metric event, and allow user programs to read the performance counters.
Fixed counter 3 is mapped to a pseudo event event=0x00, umask=04,
so the perf_event_attr structure should be initialized with
{ .config = 0x0400, .type = PERF_TYPE_RAW }
The metric events are mapped to the pseudo event event=0x00, umask=0x8X.
For example, the perf_event_attr structure can be initialized with
{ .config = 0x8000, .type = PERF_TYPE_RAW } for Retiring metric event
The Fixed counter 3 must be the leader of the group.
#include <linux/perf_event.h>
#include <sys/syscall.h>
#include <unistd.h>
/* Provide own perf_event_open stub because glibc doesn't */
__attribute__((weak))
int perf_event_open(struct perf_event_attr *attr, pid_t pid,
int cpu, int group_fd, unsigned long flags)
{
return syscall(__NR_perf_event_open, attr, pid, cpu, group_fd, flags);
}
/* Open slots counter file descriptor for current task. */
struct perf_event_attr slots = {
.type = PERF_TYPE_RAW,
.size = sizeof(struct perf_event_attr),
.config = 0x400,
.exclude_kernel = 1,
};
int slots_fd = perf_event_open(&slots, 0, -1, -1, 0);
if (slots_fd < 0)
... error ...
/*
* Open metrics event file descriptor for current task.
* Set slots event as the leader of the group.
*/
struct perf_event_attr metrics = {
.type = PERF_TYPE_RAW,
.size = sizeof(struct perf_event_attr),
.config = 0x8000,
.exclude_kernel = 1,
};
int metrics_fd = perf_event_open(&metrics, 0, -1, slots_fd, 0);
if (metrics_fd < 0)
... error ...
The RDPMC instruction (or _rdpmc compiler intrinsic) can now be used
to read slots and the topdown metrics at different points of the program:
#include <stdint.h>
#include <x86intrin.h>
#define RDPMC_FIXED (1 << 30) /* return fixed counters */
#define RDPMC_METRIC (1 << 29) /* return metric counters */
#define FIXED_COUNTER_SLOTS 3
#define METRIC_COUNTER_TOPDOWN_L1 0
static inline uint64_t read_slots(void)
{
return _rdpmc(RDPMC_FIXED | FIXED_COUNTER_SLOTS);
}
static inline uint64_t read_metrics(void)
{
return _rdpmc(RDPMC_METRIC | METRIC_COUNTER_TOPDOWN_L1);
}
Then the program can be instrumented to read these metrics at different
points.
It's not a good idea to do this with too short code regions,
as the parallelism and overlap in the CPU program execution will
cause too much measurement inaccuracy. For example instrumenting
individual basic blocks is definitely too fine grained.
Decoding metrics values
=======================
The value reported by read_metrics() contains four 8 bit fields
that represent a scaled ratio that represent the Level 1 bottleneck.
All four fields add up to 0xff (= 100%)
The binary ratios in the metric value can be converted to float ratios:
#define GET_METRIC(m, i) (((m) >> (i*8)) & 0xff)
#define TOPDOWN_RETIRING(val) ((float)GET_METRIC(val, 0) / 0xff)
#define TOPDOWN_BAD_SPEC(val) ((float)GET_METRIC(val, 1) / 0xff)
#define TOPDOWN_FE_BOUND(val) ((float)GET_METRIC(val, 2) / 0xff)
#define TOPDOWN_BE_BOUND(val) ((float)GET_METRIC(val, 3) / 0xff)
and then converted to percent for printing.
The ratios in the metric accumulate for the time when the counter
is enabled. For measuring programs it is often useful to measure
specific sections. For this it is needed to deltas on metrics.
This can be done by scaling the metrics with the slots counter
read at the same time.
Then it's possible to take deltas of these slots counts
measured at different points, and determine the metrics
for that time period.
slots_a = read_slots();
metric_a = read_metrics();
... larger code region ...
slots_b = read_slots()
metric_b = read_metrics()
# compute scaled metrics for measurement a
retiring_slots_a = GET_METRIC(metric_a, 0) * slots_a
bad_spec_slots_a = GET_METRIC(metric_a, 1) * slots_a
fe_bound_slots_a = GET_METRIC(metric_a, 2) * slots_a
be_bound_slots_a = GET_METRIC(metric_a, 3) * slots_a
# compute delta scaled metrics between b and a
retiring_slots = GET_METRIC(metric_b, 0) * slots_b - retiring_slots_a
bad_spec_slots = GET_METRIC(metric_b, 1) * slots_b - bad_spec_slots_a
fe_bound_slots = GET_METRIC(metric_b, 2) * slots_b - fe_bound_slots_a
be_bound_slots = GET_METRIC(metric_b, 3) * slots_b - be_bound_slots_a
Later the individual ratios for the measurement period can be recreated
from these counts.
slots_delta = slots_b - slots_a
retiring_ratio = (float)retiring_slots / slots_delta
bad_spec_ratio = (float)bad_spec_slots / slots_delta
fe_bound_ratio = (float)fe_bound_slots / slots_delta
be_bound_ratio = (float)be_bound_slots / slota_delta
printf("Retiring %.2f%% Bad Speculation %.2f%% FE Bound %.2f%% BE Bound %.2f%%\n",
retiring_ratio * 100.,
bad_spec_ratio * 100.,
fe_bound_ratio * 100.,
be_bound_ratio * 100.);
Resetting metrics counters
==========================
Since the individual metrics are only 8bit they lose precision for
short regions over time because the number of cycles covered by each
fraction bit shrinks. So the counters need to be reset regularly.
When using the kernel perf API the kernel resets on every read.
So as long as the reading is at reasonable intervals (every few
seconds) the precision is good.
When using perf stat it is recommended to always use the -I option,
with no longer interval than a few seconds
perf stat -I 1000 --topdown ...
For user programs using RDPMC directly the counter can
be reset explicitly using ioctl:
ioctl(perf_fd, PERF_EVENT_IOC_RESET, 0);
This "opens" a new measurement period.
A program using RDPMC for TopDown should schedule such a reset
regularly, as in every few seconds.
Limits on Ice Lake
==================
Four pseudo TopDown metric events are exposed for the end-users,
topdown-retiring, topdown-bad-spec, topdown-fe-bound and topdown-be-bound.
They can be used to collect the TopDown value under the following
rules:
- All the TopDown metric events must be in a group with the SLOTS event.
- The SLOTS event must be the leader of the group.
- The PERF_FORMAT_GROUP flag must be applied for each TopDown metric
events
The SLOTS event and the TopDown metric events can be counting members of
a sampling read group. Since the SLOTS event must be the leader of a TopDown
group, the second event of the group is the sampling event.
For example, perf record -e '{slots, $sampling_event, topdown-retiring}:S'

Requests allocate into the WPQ soon after they enter the memory controller, and need credits for an entry in this buffer before being sent from the CHA to the iMC (memory controller). They deallocate after being issued to DRAM. Write requests themselves are able to complete (from the perspective of the rest of the system) as soon they have 'posted' to the iMC. This is not to be confused with actually performing the write to DRAM. Therefore, the average latency for this queue is actually not useful for deconstruction intermediate write latencies. So, we provide filtering based on if the request has posted or not. By using the 'not posted' filter, we can track how long writes spent in the iMC before completions were sent to the HA. The 'posted' filter, on the other hand, provides information about how much queueing is actually happenning in the iMC for writes before they are actually issued to memory. High average occupancies will generally coincide with high write major mode counts. Is there a filter of sorts???",
