# HEAD: 066450be419fa48007a9f29e19828f2a86198754 perf/x86/intel/pt: Clean up the control flow in pt_pmu_hw_init()

There were tons of changes in this cycle - almost 400 commits:

Core kernel changes:

- One of the more interesting features in this cycle is the ability
to attach eBPF programs (user-defined, sandboxed bytecode executed
by the kernel) to kprobes. This allows user-defined instrumentation
on a live kernel image that can never crash, hang or interfere with
the kernel negatively. (Right now it's limited to root-only, but in
the future we might allow unprivileged use as well.)

(Alexei Starovoitov)

- Another non-trivial feature is per event clockid support: this
allows, amongst other things, the selection of different clock
sources for event timestamps traced via perf. This feature is
sought by people who'd like to merge perf generated events with
external events that were measured with different clocks:

- cluster wide profiling

- for system wide tracing with user-space events,

- JIT profiling events

etc. Matching perf tooling support is added as well, available via
the -k, --clockid <clockid> parameter to perf record et al.

(Peter Zijlstra)

Hardware enablement kernel changes:

- x86 Intel Processor Trace (PT) support: which is a hardware tracer
on steroids, available on Broadwell CPUs. The hardware trace stream
is directly output into the user-space ring-buffer, using the 'AUX'
data format extension that was added to the perf core to support
hardware constraints such as the necessity to have the tracing
buffer physically contiguous. This patch-set was developed for two
years and this is the result. A simple way to make use of this is
to use BTS tracing, the PT driver emulates BTS output - available
via the 'intel_bts' PMU. More explicit PT specific tooling support
is in the works as well - will probably be ready by 4.2.

(Alexander Shishkin, Peter Zijlstra)

- x86 Intel Cache QoS Monitoring (CQM) support: a hardware feature of
Intel Xeon CPUs that allows the measurement and
allocation/partitioning of caches to individual workloads.

These kernel changes expose the measurement side as a new PMU
driver, which exposes various QoS related PMU events. (The
partitioning change is work in progress and is planned to be merged
as a cgroup extension.)

(Matt Fleming, Peter Zijlstra; CPU feature detection by Peter P
Waskiewicz Jr)

- x86 Intel Haswell LBR call stack support: this is a new Haswell
feature that allows the hardware recording of call chains, plus
tooling support. To activate this feature you have to enable it
via the new 'lbr' call-graph recording option:

perf record --call-graph lbr
perf report


perf top --call-graph lbr

This hardware feature is a lot faster than stack walk or dwarf
based unwinding, but has some limitations:

- It reuses the current LBR facility, so LBR call stack and branch
record can not be enabled at the same time.

- It is only available for user-space callchains.

(Yan, Zheng)

- x86 Intel Broadwell CPU support and various event constraints and
event table fixes for earlier models.

(Andi Kleen)

- x86 Intel HT CPUs event scheduling workarounds. This is a complex
CPU bug affecting the SNB,IVB,HSW families that results in counter
value corruption. The mitigation code is automatically enabled and
is transparent.

(Maria Dimakopoulou, Stephane Eranian)

The perf tooling side had a ton of changes in this cycle as well, so
I'm only able to list the user visible changes here, in addition to
the tooling changes outlined above:

User visible changes affecting all tools:

- Improve support of compressed kernel modules (Jiri Olsa)
- Save DSO loading errno to better report errors (Arnaldo Carvalho de Melo)
- Bash completion for subcommands (Yunlong Song)
- Add 'I' event modifier for perf_event_attr.exclude_idle bit (Jiri Olsa)
- Support missing -f to override perf.data file ownership. (Yunlong Song)
- Show the first event with an invalid filter (David Ahern, Arnaldo Carvalho de Melo)

User visible changes in individual tools:

'perf data': New tool for converting perf.data to other formats, initially for the
CTF (Common Trace Format) from LTTng (Jiri Olsa, Sebastian Siewior)

'perf diff':
- Add --kallsyms option (David Ahern)

'perf list':

- Allow listing events with 'tracepoint' prefix (Yunlong Song)
- Sort the output of the command (Yunlong Song)

'perf kmem':

- Respect -i option (Jiri Olsa)
- Print big numbers using thousands' group (Namhyung Kim)
- Allow -v option (Namhyung Kim)
- Fix alignment of slab result table (Namhyung Kim)

'perf probe':

- Support multiple probes on different binaries on the same command line (Masami Hiramatsu)
- Support unnamed union/structure members data collection. (Masami Hiramatsu)
- Check kprobes blacklist when adding new events. (Masami Hiramatsu)

'perf record':

- Teach 'perf record' about perf_event_attr.clockid (Peter Zijlstra)
- Support recording running/enabled time (Andi Kleen)

'perf sched':

- Improve the performance of 'perf sched replay' on high CPU core count machines (Yunlong Song)

'perf report' and 'perf top':

- Allow annotating entries in callchains in the hists browser (Arnaldo Carvalho de Melo)

- Indicate which callchain entries are annotated in the
TUI hists browser (Arnaldo Carvalho de Melo)

- Add pid/tid filtering to 'report' and 'script' commands (David Ahern)

- Consider PERF_RECORD_ events with cpumode == 0 in 'perf top', removing one
cause of long term memory usage buildup, i.e. not processing PERF_RECORD_EXIT
events (Arnaldo Carvalho de Melo)

'perf stat':

- Report unsupported events properly (Suzuki K. Poulose)
- Output running time and run/enabled ratio in CSV mode (Andi Kleen)

'perf trace':

- Handle legacy syscalls tracepoints (David Ahern, Arnaldo Carvalho de Melo)

- Only insert blank duration bracket when tracing syscalls (Arnaldo Carvalho de Melo)

- Filter out the trace pid when no threads are specified (Arnaldo Carvalho de Melo)

- Dump stack on segfaults (Arnaldo Carvalho de Melo)

- No need to explicitely enable evsels for workload started from perf, let it
be enabled via perf_event_attr.enable_on_exec, removing some events that take
place in the 'perf trace' before a workload is really started by it.
(Arnaldo Carvalho de Melo)

- Allow mixing with tracepoints and suppressing plain syscalls. (Arnaldo Carvalho de Melo)

There's also been a ton of infrastructure work done, such as the
split-out of perf's build system into tools/build/ and other changes -
see the shortlog and changelog for details.
