846e193980 perf ftrace: Add option '-m/--buffer-size' to set per-cpu buffer size 
This adds an option '-m/--buffer-size' to allow us set the size of per-cpu
tracing buffer.

Committer testing:

Before running with this option:

  # find /sys/kernel/tracing/ -name buffer_size_kb | xargs cat
  1408
  1408
  1408
  1408
  1408
  1408
  1408
  1408
  1408
  #

Then, run:

  # perf ftrace -m 2048K | head -10
   2)               |  mutex_unlock() {
   2)   ==========> |
   2)               |    smp_irq_work_interrupt() {
   2)               |      irq_enter() {
   2)   0.121 us    |        rcu_irq_enter();
   2)   0.128 us    |        irqtime_account_irq();
   2)   0.719 us    |      }
   2)               |      __wake_up() {
   2)               |        __wake_up_common_lock() {
   2)   0.105 us    |          _raw_spin_lock_irqsave();
  #

Now look at those tracefs knobs:

  # find /sys/kernel/tracing/ -name buffer_size_kb | xargs cat
  2048
  2048
  2048
  2048
  2048
  2048
  2048
  2048
  2048
  #

This should be similar to the -m option in the other perf tools, such as
'perf record', 'perf trace', etc.

eb6d31ae22 perf ftrace: Select function/function_graph tracer automatically 
The '-g/-G' options have already implied function_graph tracer should be
used instead of function tracer. So we don't need extra option
'--tracer' in this case.

This patch changes the behavior as below:

  - If '-g' or '-G' option is on, then function_graph tracer is used.
  - If '-T' or '-N' option is on, then function tracer is used.
  - The function_graph has priority over function tracer.
  - The option '--tracer' only take effect if neither -g/-G nor -T/-N
    is specified.

Here are some examples.

This will start tracing all functions using default tracer:

  $ sudo perf ftrace

This will trace all functions using function graph tracer:

  $ sudo perf ftrace -G '*'

This will trace function vfs_read using function graph tracer:

  $ sudo perf ftrace -G vfs_read

This will trace function vfs_read using function tracer:

  $ sudo perf ftrace -T vfs_read

Committer notes:

Using '-h -G' will tell what that option is about, so to further clarify
the above examples:

  # perf ftrace -h -G

    -G, --graph-funcs <func>	Set graph filter on given functions

  # perf ftrace -h -g

    -g, --nograph-funcs <func>	Set nograph filter on given functions

  # perf ftrace -h -T

    -T, --trace-funcs <func>	trace given functions only

  # perf ftrace -h -N

    -N, --notrace-funcs <func>	do not trace given functions

  #

2db13a9b30 perf bench numa: Use numa_node_to_cpus() to bind tasks to nodes 
It is currently assumed that each node contains at most nr_cpus/nr_nodes
CPUs and nodes' CPU ranges do not overlap.

That assumption is generally incorrect as there are archs where a CPU
number does not depend on to its node number.

This update removes the described assumption by simply calling
numa_node_to_cpus() interface and using the returned mask for binding
CPUs to nodes.

Also, variable types and names made consistent in functions using
cpumask.

fa5c893181 tools build feature: Quote CC and CXX for their arguments 
When using a cross-compilation environment, such as OpenEmbedded,
the CC an CXX variables are set to something more than just a
command: there are arguments (such as --sysroot) that need to be
passed on to the compiler so that the right set of headers and
libraries are used.

For the particular case that our systems detected, CC is set to
the following:

  export CC="aarch64-linaro-linux-gcc  --sysroot=/oe/build/tmp/work/machine/perf/1.0-r9/recipe-sysroot"

b2fe96a350 perf tools: Fix module symbol processing 
The 'dso->kernel' condition is true also for kernel modules now,
and there are several places that were omited by the initial change:

  - we need to identify modules separately in dso__process_kernel_symbol
  - we need to set 'dso->kernel' for module from buildid table
  - there's no need to use 'dso->kernel || kmodule' in one condition

Committer testing:

Rename enum dso_kernel_type to enum dso_space_type, which seems like
better fit.

Committer notes:

This is used with 'struct dso'->kernel, which once was a boolean, so
DSO_SPACE__USER is zero, !zero means some sort of kernel space, be it
the host kernel space or a guest kernel space.

194cb6b50f perf test: Allow multiple probes in record+script_probe_vfs_getname.sh 
Sometimes when adding a kprobe by perf, it results in multiple probe
points, such as the following:

  # ./perf probe -l
    probe:vfs_getname    (on getname_flags:73@fs/namei.c with pathname)
    probe:vfs_getname_1  (on getname_flags:73@fs/namei.c with pathname)
    probe:vfs_getname_2  (on getname_flags:73@fs/namei.c with pathname)
  # cat /sys/kernel/debug/tracing/kprobe_events
  p:probe/vfs_getname _text+5501804 pathname=+0(+0(%gpr31)):string
  p:probe/vfs_getname_1 _text+5505388 pathname=+0(+0(%gpr31)):string
  p:probe/vfs_getname_2 _text+5508396 pathname=+0(+0(%gpr31)):string

In this test, we need to record all of them and expect any of them in
the perf-script output, since it's not clear which one will be used for
the desired syscall:

  # perf stat -e probe:vfs_getname\* -- touch /tmp/nic

   Performance counter stats for 'touch /tmp/nic':

                31      probe:vfs_getname_2
                 0      probe:vfs_getname_1
                 1      probe:vfs_getname
       0.001421826 seconds time elapsed

       0.001506000 seconds user
       0.000000000 seconds sys

If the test relies only on probe:vfs_getname, it might easily miss the
relevant data.

1beaef29c3 perf bench mem: Always memset source before memcpy 
For memcpy, the source pages are memset to zero only when --cycles is
used.  This leads to wildly different results with or without --cycles,
since all sources pages are likely to be mapped to the same zero page
without explicit writes.

Before this fix:

$ export cmd="./perf stat -e LLC-loads -- ./perf bench \
  mem memcpy -s 1024MB -l 100 -f default"
$ $cmd

Commit fbd705a0c6 ("sched: Introduce the 'trace_sched_waking'
tracepoint") added sched_waking tracepoint which should be preferred
over sched_wakeup when analyzing scheduling delays.

Update 'perf sched record' to collect sched_waking events if it exists
and fallback to sched_wakeup if it does not. Similarly, update timehist
command to skip sched_wakeup events if the session includes sched_waking
(ie., sched_waking is preferred over sched_wakeup).

f3cf7fa963 perf trace beauty: Use the autogenerated protocol family table 
That helps us not to lose new protocol families when they are
introduced, replacing that hardcoded, dated family->string table.

To recap what this allows us to do:

  # perf trace -e syscalls:sys_enter_socket/max-stack=10/ --filter=family==INET --max-events=1
     0.000 fetchmail/41097 syscalls:sys_enter_socket(family: INET, type: DGRAM|CLOEXEC|NONBLOCK, protocol: IP)
                                       __GI___socket (inlined)
                                       reopen (/usr/lib64/libresolv-2.31.so)
                                       send_dg (/usr/lib64/libresolv-2.31.so)
                                       __res_context_send (/usr/lib64/libresolv-2.31.so)
                                       __GI___res_context_query (inlined)
                                       __GI___res_context_search (inlined)

                                       __GI_getaddrinfo (inlined)
                                       [0x15cb2] (/usr/bin/fetchmail)
  #

More work is still needed to allow for the more natura strace-like
syscall name usage instead of the trace event name:

  # perf trace -e socket/max-stack=10,family==INET/ --max-events=1

I.e. to allow for modifiers to follow the syscall name and for logical
expressions to be accepted as filters to use with that syscall, be it as
trace event filters or BPF based ones.

Using -v we can see how the trace event filter is built:

  # perf trace -v -e syscalls:sys_enter_socket/call-graph=dwarf/ --filter=family==INET --max-events=2
  <SNIP>
  New filter for syscalls:sys_enter_socket: (family==0x2) && (common_pid != 41384 && common_pid != 2836)
  <SNIP>

  $ tools/perf/trace/beauty/socket.sh | grep -w 2

  };
  $

This uses a copy of include/linux/socket.h that is kept in a directory
to be used just for these table generation scripts and for checking if
the kernel has a new file that maybe gets something new for these
tables.

This allows us to:

- Avoid accessing files outside tools/, in the kernel sources, that may
  be changed in unexpected ways and thus break these scripts.

- Notice when those files change and thus check if the changes don't
  break those scripts, update them to automatically get the new
  definitions, a new socket family, for instance.

- Not add then to the tools/include/ where it may end up used while
  building the tools and end up requiring dragging yet more stuff from
  the kernel or plain break the build in some of the myriad environments
  where perf may be built.

This will replace the previous static array in tools/perf/ that was
dated and was already missing the AF_KCM, AF_QIPCRTR, AF_SMC and AF_XDP
families.

The next cset will wire this up to the perf build process.

At some point this must be made into a library to be used in places such
as libtraceevent, bpftrace, etc.

617e7481d7 remoteproc updates for v5.9 
This introduces a new "detached" state for remote processors that are
 deemed to be running at the time Linux boots and the infrastructure for
 "attaching" to these. It then introduces the support for performing this
 operation for the STM32 platform.
 
 The coredump functionality is moved out from the core file and gains
 support for an optional mode where the recovery phase awaits the
 notification from devcoredump that the dump should be released. This
 allows userspace to grab the coredump in scenarios where vmalloc space
 is too low for creating a complete copy of the coredump before handing
 this to devcoredump.
 
 A new character device based interface is introduced to allow tying the
 stoppage of a remote processor to the termination of a user space
 process. This is useful in situations when such process provides crucial
 resources/operations for the firmware running on the remote processor.
 
 The Texas Instrument K3 driver gains support for the C66x and C71x DSPs.
 
 Qualcomm remoteprocs gains support for stashing relocation information
 in IMEM, to aid post mortem debugging and the crash notification
 mechanism is generalized to be reusable in cases where loosely coupled
 drivers needs to know about the status of a remote processor. One such
 example is the IPA hardware block, which is jointly owned with the
 modem and migrated to this improved interface.
 
 It also introduces a number of bug fixes and debug improvements for the
 Qualcomm modem remoteproc driver.
 
 And it cleans up the inconsistent interface for remoteproc drivers to
 implement power management.

4c96870e58 zonefs: update documentation to reflect zone size vs capacity 
Update the zonefs documentation to reflect the difference between a zone's
size and it's capacity.

The maximum file size in zonefs is the zones capacity, for ZBC and ZAC
based devices, which do not have a separate zone capacity, the zone
capacity is equal to the zone size.

e3c3155bc9 zonefs: add zone-capacity support 
In the zoned storage model, the sectors within a zone are typically all
writeable. With the introduction of the Zoned Namespace (ZNS) Command
Set in the NVM Express organization, the model was extended to have a
specific writeable capacity.

This zone capacity can be less than the overall zone size for a NVMe ZNS
device or null_blk in zoned-mode. For other ZBC/ZAC devices the zone
capacity is always equal to the zone size.

Use the zone capacity field instead from blk_zone for determining the
maximum inode size and inode blocks in zonefs.

00e4db5125 perf tools changes for v5.9 
New features:
 
 - Introduce controlling how 'perf stat' and 'perf record' works via a
   control file descriptor, allowing starting with events configured but
   disabled until commands are received via the control file descriptor.
   This allows, for instance for tools such as Intel VTune to make further
   use of perf as its Linux platform driver.
 
 - Improve 'perf record' to to register in a perf.data file header the clockid
   used to help later correlate things like syslog files and perf events
   recorded.
 
 - Add basic syscall and find_next_bit benchmarks to 'perf bench'.
 
 - Allow using computed metrics in calculating other metrics. For instance:
 
   {
     .metric_expr    = "l2_rqsts.demand_data_rd_hit + l2_rqsts.pf_hit + l2_rqsts.rfo_hit",
     .metric_name    = "DCache_L2_All_Hits",
   },
   {
     .metric_expr    = "max(l2_rqsts.all_demand_data_rd - l2_rqsts.demand_data_rd_hit, 0) + l2_rqsts.pf_miss + l2_rqsts.rfo_miss",
     .metric_name    = "DCache_L2_All_Miss",
   },
   {
      .metric_expr    = "dcache_l2_all_hits + dcache_l2_all_miss",
      .metric_name    = "DCache_L2_All",
   }
 
 - Add suport for 'd_ratio', '>' and '<' operators to the expression resolver used
   in calculating metrics in 'perf stat'.
 
 Support for new kernel features:
 
 - Support TEXT_POKE and KSYMBOL_TYPE_OOL perf metadata events to cope with
   things like ftrace, trampolines, i.e. changes in the kernel text that gets
   in the way of properly decoding Intel PT hardware traces, for instance.
 
 Intel PT:
 
 - Add various knobs to reduce the volume of Intel PT traces by reducing the
   level of details such as decoding just some types of packets (e.g., FUP/TIP,
   PSB+), also filtering by time range.
 
 - Add new itrace options (log flags to the 'd' option, error flags to the 'e'
   one, etc), controlling how Intel PT is transformed into perf events, document
   some missing options (e.g., how to synthesize callchains).
 
 BPF:
 
 - Properly report BPF errors when parsing events.
 
 - Do not setup side-band events if LIBBPF is not linked, fixing a segfault.
 
 Libraries:
 
 - Improvements on the libtraceevent plugin mechanism.
 
 - Improve libtracevent support for KVM trace events SVM exit reasons.
 
 - Add a libtracevent plugins for decoding syscalls/sys_enter_futex and for tlb_flush.
 
 - Ensure sample_period is set libpfm4 events in 'perf test'.
 
 - Fixup libperf namespacing, to make sure what is in libperf has the perf_
   namespace while what is now only in tools/perf/ doesn't use that prefix.
 
 Arch specific:
 
 - Improve the testing of vendor events and metrics in 'perf test'.
 
 - Allow no ARM CoreSight hardware tracer sink to be specified on command line.
 
 - Fix arm_spe_x recording when mixed with other perf events.
 
 - Add s390 idle functions 'psw_idle' and 'psw_idle_exit' to list of idle symbols.
 
 - List kernel supplied event aliases for arm64 in 'perf list'.
 
 - Add support for extended register capability in PowerPC 9 and 10.
 
 - Added nest IMC power9 metric events.
 
 Miscellaneous:
 
 - No need to setup sample_regs_intr/sample_regs_user for dummy events.
 
 - Update various copies of kernel headers, some causing perf to handle new
   syscalls, MSRs, etc.
 
 - Improve usage of flex and yacc, enabling warnings and addressing the fallout.
 
 - Add missing '--output' option to 'perf kmem' so that it can pass it along to 'perf record'.
 
 - 'perf probe' fixes related to adding multiple probes on the same address for
   the same event.
 
 - Make 'perf probe' warn if the target function is a GNU indirect function.
 
 - Remove //anon mmap events from 'perf inject jit' to fix supporting both using
   ELF files for generated functions and the perf-PID.map approaches.

 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.
 
 fedora:rawhide with python3 and gcc 10.1.1-2 is failing (10.1.1-1 on fedora:32
 works), fixes will be provided soon.
 
 clearlinux:latest is failing on libbpf, there is a fix already in the bpf tree.
 
 The ones failing when linking with libllvm, not the default build, were
 restricted to clang-9/llvm-9, working with anything before or after, e.g.,
 using clang-8 on ubuntu:19.10 and clang-11 on debian:experimental fixed the
 build in those environments.

Merge tag 'perf-tools-2020-08-10' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tools updates from Arnaldo Carvalho de Melo:
 "New features:

   - Introduce controlling how 'perf stat' and 'perf record' works via a
     control file descriptor, allowing starting with events configured
     but disabled until commands are received via the control file
     descriptor. This allows, for instance for tools such as Intel VTune
     to make further use of perf as its Linux platform driver.

   - Improve 'perf record' to to register in a perf.data file header the
     clockid used to help later correlate things like syslog files and
     perf events recorded.

   - Add basic syscall and find_next_bit benchmarks to 'perf bench'.

   - Allow using computed metrics in calculating other metrics. For
     instance:

	  {
	    .metric_expr    = "l2_rqsts.demand_data_rd_hit + l2_rqsts.pf_hit + l2_rqsts.rfo_hit",
	    .metric_name    = "DCache_L2_All_Hits",
	  },
	  {
	    .metric_expr    = "max(l2_rqsts.all_demand_data_rd - l2_rqsts.demand_data_rd_hit, 0) + l2_rqsts.pf_miss + l2_rqsts.rfo_miss",
	    .metric_name    = "DCache_L2_All_Miss",
	  },
	  {
	     .metric_expr    = "dcache_l2_all_hits + dcache_l2_all_miss",
	     .metric_name    = "DCache_L2_All",
	  }

   - Add suport for 'd_ratio', '>' and '<' operators to the expression
     resolver used in calculating metrics in 'perf stat'.

  Support for new kernel features:

   - Support TEXT_POKE and KSYMBOL_TYPE_OOL perf metadata events to cope
     with things like ftrace, trampolines, i.e. changes in the kernel
     text that gets in the way of properly decoding Intel PT hardware
     traces, for instance.

  Intel PT:

   - Add various knobs to reduce the volume of Intel PT traces by
     reducing the level of details such as decoding just some types of
     packets (e.g., FUP/TIP, PSB+), also filtering by time range.

   - Add new itrace options (log flags to the 'd' option, error flags to
     the 'e' one, etc), controlling how Intel PT is transformed into
     perf events, document some missing options (e.g., how to synthesize
     callchains).

  BPF:

   - Properly report BPF errors when parsing events.

   - Do not setup side-band events if LIBBPF is not linked, fixing a
     segfault.

  Libraries:

   - Improvements to the libtraceevent plugin mechanism.

   - Improve libtracevent support for KVM trace events SVM exit reasons.

   - Add a libtracevent plugins for decoding syscalls/sys_enter_futex
     and for tlb_flush.

   - Ensure sample_period is set libpfm4 events in 'perf test'.

   - Fixup libperf namespacing, to make sure what is in libperf has the
     perf_ namespace while what is now only in tools/perf/ doesn't use
     that prefix.

  Arch specific:

   - Improve the testing of vendor events and metrics in 'perf test'.

   - Allow no ARM CoreSight hardware tracer sink to be specified on
     command line.

   - Fix arm_spe_x recording when mixed with other perf events.

   - Add s390 idle functions 'psw_idle' and 'psw_idle_exit' to list of
     idle symbols.

   - List kernel supplied event aliases for arm64 in 'perf list'.

   - Add support for extended register capability in PowerPC 9 and 10.

   - Added nest IMC power9 metric events.

  Miscellaneous:

   - No need to setup sample_regs_intr/sample_regs_user for dummy
     events.

   - Update various copies of kernel headers, some causing perf to
     handle new syscalls, MSRs, etc.

   - Improve usage of flex and yacc, enabling warnings and addressing
     the fallout.

   - Add missing '--output' option to 'perf kmem' so that it can pass it
     along to 'perf record'.

   - 'perf probe' fixes related to adding multiple probes on the same
     address for the same event.

   - Make 'perf probe' warn if the target function is a GNU indirect
     function.

   - Remove //anon mmap events from 'perf inject jit' to fix supporting
     both using ELF files for generated functions and the perf-PID.map
     approaches"
