Merge tag 'parisc-for-6.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

Pull parisc updates from Helge Deller:
 "There is one noteable patch, which allows the parisc kernel to use the
  same MADV_xxx constants as the other architectures going forward. With
  that change only alpha has one entry left (MADV_DONTNEED is 6 vs 4 on
  others) which is different. To prevent an ABI breakage, a wrapper is
  included which translates old MADV values to the new ones, so existing
  userspace isn't affected. Reason for that patch is, that some
  applications wrongly used the standard MADV_xxx values even on some
  non-x86 platforms and as such those programs failed to run correctly
  on parisc (examples are qemu-user, tor browser and boringssl).

  Then the kgdb console and the LED code received some fixes, and some
  0-day warnings are now gone. Finally, the very last compile warning
  which was visible during a kernel build is now fixed too (in the vDSO
  code).

  The majority of the patches are tagged for stable series and in
  summary this patchset is quite small and drops more code than it adds:

Fixes:
   - Fix potential null-ptr-deref in start_task()
   - Fix kgdb console on serial port
   - Add missing FORCE prerequisites in Makefile
   - Drop PMD_SHIFT from calculation in pgtable.h

  Enhancements:
   - Implement a wrapper to align madvise() MADV_* constants with other
     architectures
   - If machine supports running MPE/XL, show the MPE model string

   - Indenting fixes in setup_cmdline()"

Helge Deller 71bdea6f79 parisc: Align parisc MADV_XXX constants with all other architectures
Adjust some MADV_XXX constants to be in sync what their values are on
all other platforms. There is currently no reason to have an own
numbering on parisc, but it requires workarounds in many userspace
sources (e.g. glibc, qemu, ...) - which are often forgotten and thus
introduce bugs and different behaviour on parisc.

A wrapper avoids an ABI breakage for existing userspace applications by
translating any old values to the new ones, so this change allows us to
move over all programs to the new ABI over time.

Sean Christopherson 49bd97c28b perf tools: Use dedicated non-atomic clear/set bit helpers
Use the dedicated non-atomic helpers for {clear,set}_bit() and their
test variants, i.e. the double-underscore versions.  Depsite being
defined in atomic.h, and despite the kernel versions being atomic in the
kernel, tools' {clear,set}_bit() helpers aren't actually atomic.  Move
to the double-underscore versions so that the versions that are expected
to be atomic (for kernel developers) can be made atomic without
affecting users that don't want atomic operations.

No functional change intended.

Dmitry Vyukov 68a6772f11 perf bench: Add breakpoint benchmarks
Add 2 benchmarks:

1. Performance of thread creation/exiting in presence of breakpoints.
2. Performance of breakpoint modification in presence of threads.

The benchmarks capture use cases that we are interested in:
using inheritable breakpoints in large highly-threaded applications.

The benchmarks show significant slowdown imposed by breakpoints
(even when they don't fire).

Testing on Intel 8173M with 112 HW threads show:

  perf bench --repeat=56 breakpoint thread --breakpoints=0 --parallelism=56 --threads=20
        78.675000 usecs/op
  perf bench --repeat=56 breakpoint thread --breakpoints=4 --parallelism=56 --threads=20
     12967.135714 usecs/op

That's 165x slowdown due to presence of the breakpoints.

  perf bench --repeat=20000 breakpoint enable --passive=0 --active=0
         1.433250 usecs/op
  perf bench --repeat=20000 breakpoint enable --passive=224 --active=0
       585.318400 usecs/op
  perf bench --repeat=20000 breakpoint enable --passive=0 --active=111
       635.953000 usecs/op

That's 408x and 444x slowdown due to presence of threads.

Profiles show some overhead in toggle_bp_slot,
but also very high contention:

    90.83%  breakpoint-thre  [kernel.kallsyms]  [k] osq_lock
     4.69%  breakpoint-thre  [kernel.kallsyms]  [k] mutex_spin_on_owner

Athira Rajeev f58faed7fb perf bench: Fix numa bench to fix usage of affinity for machines with #CPUs > 1K
The 'perf bench numa' testcase fails on systems with more than 1K CPUs.

Testcase: perf bench numa mem -p 1 -t 3 -P 512 -s 100 -zZ0qcm --thp  1

Snippet of code:

  <<>>
  perf: bench/numa.c:302: bind_to_node: Assertion `!(ret)' failed.
  Aborted (core dumped)
  <<>>

bind_to_node() uses "sched_getaffinity" to save the original cpumask and
this call is returning EINVAL ((invalid argument).

This happens because the default mask size in glibc is 1024.  To
overcome this 1024 CPUs mask size limitation of cpu_set_t, change the
mask size using the CPU_*_S macros ie, use CPU_ALLOC to allocate
cpumask, CPU_ALLOC_SIZE for size.

Apart from fixing this for "orig_mask", apply same logic to "mask" as
well which is used to setaffinity so that mask size is large enough to
represent number of possible CPU's in the system.

sched_getaffinity is used in one more place in perf numa bench. It is in
"bind_to_cpu" function. Apply the same logic there also. Though
currently no failure is reported from there, it is ideal to change
getaffinity to work with such system configurations having CPU's more
than default mask size supported by glibc.

Also fix "sched_setaffinity" to use mask size which is large enough to
represent number of possible CPU's in the system.

Fixed all places where "bind_cpumask" which is part of "struct
thread_data" is used such that bind_cpumask works in all configuration.

Athira Rajeev 8cb7a188ac perf bench: Fix numa testcase to check if CPU used to bind task is online
Perf numa bench test fails with error:

Testcase:

  ./perf bench numa mem -p 2 -t 1 -P 1024 -C 0,8 -M 1,0 -s 20 -zZq --thp  1 --no-data_rand_walk

Failure snippet:

<<>>
  Running 'numa/mem' benchmark:

  # Running main, "perf bench numa numa-mem -p 2 -t 1 -P 1024 -C 0,8 -M 1,0 -s 20 -zZq --thp 1 --no-data_rand_walk"

  perf: bench/numa.c:333: bind_to_cpumask: Assertion `!(ret)' failed.
<<>>

The Testcases uses CPU's 0 and 8. In function "parse_setup_cpu_list",
There is check to see if cpu number is greater than max cpu's possible
in the system ie via "if (bind_cpu_0 >= g->p.nr_cpus || bind_cpu_1 >=
g->p.nr_cpus) {".

But it could happen that system has say 48 CPU's, but only number of
online CPU's is 0-7. Other CPU's are offlined. Since "g->p.nr_cpus" is
48, so function will go ahead and set bit for CPU 8 also in cpumask (
td->bind_cpumask).

bind_to_cpumask function is called to set affinity using
sched_setaffinity and the cpumask. Since the CPU8 is not present, set
affinity will fail here with EINVAL.

Fix this issue by adding a check to make sure that, CPU's provided in
the input argument values are online before proceeding further and skip
the test. For this, include new helper function "is_cpu_online" in
"tools/perf/util/header.c".

Since "BIT(x)" definition will get included from header.h, remove
that from bench/numa.c

Athira Rajeev 299687e18a perf bench: Fix epoll bench to correct usage of affinity for machines with #CPUs > 1K
The 'perf bench epoll' testcase fails on systems with more than 1K CPUs.

Testcase: perf bench epoll all

Result snippet:
<<>>
Run summary [PID 106497]: 1399 threads monitoring on 64 file-descriptors for 8 secs.

perf: pthread_create: No such file or directory
<<>>

In epoll benchmarks (ctl, wait) pthread_create is invoked in do_threads
from respective bench_epoll_*  function. Though the logs shows direct
failure from pthread_create, the actual failure is from
"sched_setaffinity" returning EINVAL (invalid argument).

This happens because the default mask size in glibc is 1024. To overcome
this 1024 CPUs mask size limitation of cpu_set_t, change the mask size
using the CPU_*_S macros.

Patch addresses this by fixing all the epoll benchmarks to use CPU_ALLOC
to allocate cpumask, CPU_ALLOC_SIZE for size, and CPU_SET_S to set the
mask.

Athira Rajeev c9c2a427dd perf bench: Fix futex bench to correct usage of affinity for machines with #CPUs > 1K
The 'perf bench futex' testcase fails on systems with more than 1K CPUs.

Testcase: perf bench futex all

Failure snippet:
<<>>Running futex/hash benchmark...

perf: pthread_create: No such file or directory
<<>>

All the futex benchmarks (ie hash, lock-api, requeue, wake,
wake-parallel), pthread_create is invoked in respective bench_futex_*
function. Though the logs shows direct failure from pthread_create,
strace logs showed that actual failure is from  "sched_setaffinity"
returning EINVAL (invalid argument).

This happens because the default mask size in glibc is 1024. To overcome
this 1024 CPUs mask size limitation of cpu_set_t, change the mask size
using the CPU_*_S macros.

Ian Rogers 0df6ade711 perf evlist: Rename cpus to user_requested_cpus
evlist contains cpus and all_cpus. all_cpus is the union of the cpu maps
of all evsels.

For non-task targets, cpus is set to be cpus requested from the command
line, defaulting to all online cpus if no cpus are specified.

For an uncore event, all_cpus may be just CPU 0 or every online CPU.

This causes all_cpus to have fewer values than the cpus variable which
is confusing given the 'all' in the name.

To try to make the behavior clearer, rename cpus to user_requested_cpus
and add comments on the two struct variables.

Ian Rogers 6d18804b96 perf cpumap: Give CPUs their own type
A common problem is confusing CPU map indices with the CPU, by wrapping
the CPU with a struct then this is avoided. This approach is similar to
atomic_t.

Committer notes:

To make it build with BUILD_BPF_SKEL=1 these files needed the
conversions to 'struct perf_cpu' usage:

  tools/perf/util/bpf_counter.c
  tools/perf/util/bpf_counter_cgroup.c
  tools/perf/util/bpf_ftrace.c

Also perf_env__get_cpu() was removed back in "perf cpumap: Switch
cpu_map__build_map to cpu function".

Additionally these needed to be fixed for the ARM builds to complete:

  tools/perf/arch/arm/util/cs-etm.c
  tools/perf/arch/arm64/util/pmu.c

Alistair Francis c1ff12dac4 perf bench futex: Add support for 32-bit systems with 64-bit time_t
Some 32-bit architectures (such are 32-bit RISC-V) only have a 64-bit
time_t and as such don't have the SYS_futex syscall. This patch will
allow us to use the SYS_futex_time64 syscall on those platforms.

This also converts the futex calls to be y2038 safe (when built for a
5.1+ kernel).

Alistair Francis fec5c3a515 perf bench futex: Call the futex syscall from a function
In preparation for a more complex futex() function let's convert the
current macro into two functions. We need two functions to avoid
compiler failures as the macro is overloaded.

This will allow us to include pre-processor conditionals in the futex
syscall functions.

Namhyung Kim 84111b9c95 perf tools: Allow controlling synthesizing PERF_RECORD_ metadata events during record
Depending on the use case, it might require some kind of synthesizing
and some not.  Make it controllable to turn off heavy operations like
MMAP for all tasks.

Currently all users are converted to enable all the synthesis by
default.  It'll be updated in the later patch.

Riccardo Mancini 4241eabf59 perf bench: Add benchmark for evlist open/close operations
This new benchmark finds the total time that is taken to open, mmap,
enable, disable, munmap, close an evlist (time taken for new,
create_maps, config, delete is not counted in).

The evlist can be configured as in perf-record using the
-a,-C,-e,-u,--per-thread,-t,-p options.

The events can be duplicated in the evlist to quickly test performance
with many events using the -n options.

Furthermore, also the number of iterations used to calculate the
statistics is customizable.

Examples:
- Open one dummy event system-wide:

  $ sudo ./perf bench internals evlist-open-close
    Number of cpus:       4
    Number of threads:    1
    Number of events:     1 (4 fds)
    Number of iterations: 100
    Average open-close took: 613.870 usec (+- 32.852 usec)

- Open the group '{cs,cycles}' on CPU 0

  $ sudo ./perf bench internals evlist-open-close -e '{cs,cycles}' -C 0
    Number of cpus:       1
    Number of threads:    1
    Number of events:     2 (2 fds)
    Number of iterations: 100
    Average open-close took: 8503.220 usec (+- 252.652 usec)

- Open 10 'cycles' events for user 0, calculate average over 100 runs

  $ sudo ./perf bench internals evlist-open-close -e cycles -n 10 -u 0 -i 100
    Number of cpus:       4
    Number of threads:    328
    Number of events:     10 (13120 fds)
    Number of iterations: 100
    Average open-close took: 180043.140 usec (+- 2295.889 usec)

Committer notes:

Replaced a deprecated bzero() call with designated initialized zeroing.

Added some missing evlist allocation checks, one noted by Riccardo on
the mailing list.

Minor cosmetic changes (sent in private).

Athira Rajeev 394e4306b0 perf bench numa: Fix the condition checks for max number of NUMA nodes
In systems having higher node numbers available like node
255, perf numa bench will fail with SIGABORT.

  <<>>
  perf: bench/numa.c:1416: init: Assertion `!(g->p.nr_nodes > 64 || g->p.nr_nodes < 0)' failed.
  Aborted (core dumped)
  <<>>

Snippet from 'numactl -H' below on a powerpc system where the highest
node number available is 255:

  available: 6 nodes (0,8,252-255)
  node 0 cpus: <cpu-list>
  node 0 size: 519587 MB
  node 0 free: 516659 MB
  node 8 cpus: <cpu-list>
  node 8 size: 523607 MB
  node 8 free: 486757 MB
  node 252 cpus:
  node 252 size: 0 MB
  node 252 free: 0 MB
  node 253 cpus:
  node 253 size: 0 MB
  node 253 free: 0 MB
  node 254 cpus:
  node 254 size: 0 MB
  node 254 free: 0 MB
  node 255 cpus:
  node 255 size: 0 MB
  node 255 free: 0 MB
  node distances:
  node   0   8  252  253  254  255

Note: <cpu-list> expands to actual cpu list in the original output.
These nodes 252-255 are to represent the memory on GPUs and are valid
nodes.

The perf numa bench init code has a condition check to see if the number
of NUMA nodes (nr_nodes) exceeds MAX_NR_NODES. The value of MAX_NR_NODES
defined in perf code is 64. And the 'nr_nodes' is the value from
numa_max_node() which represents the highest node number available in the
system. In some systems where we could have NUMA node 255, this condition
check fails and results in SIGABORT.

The numa benchmark uses static value of MAX_NR_NODES in the code to
represent size of two NUMA node arrays and node bitmask used for setting
memory policy. Patch adds a fix to dynamically allocate size for the
two arrays and bitmask value based on the node numbers available in the
system. With the fix, perf numa benchmark will work with node configuration
on any system and thus removes the static MAX_NR_NODES value.

- 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.

 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.
