Subject: [RFC GIT PULL] perf tooling updates for v5.2

Linus,

Please pull the latest perf-core-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-core-for-linus

   # HEAD: 62e1c09418fc16d27720b128275cac61367e2c1b Merge tag 'perf-core-for-mingo-5.2-20190517' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

I have marked this RFC too, because Arnaldo was on vaction until a few 
days ago, so these changes were both delayed and committed late.

But perf tooling has been exceptionally good in test coverage and in 
handling of any regressions quickly, and it's also largely decoupled from 
the kernel proper and these changes don't change the kernel side, so I 
think an exception might be warranted.

Should you decide to pull it, here's the tooling changes in the tree:

* perf.data:

  Alexey Budankov:

  - Streaming compression of perf ring buffer into PERF_RECORD_COMPRESSED
    user space records, resulting in ~3-5x perf.data file size reduction
    on variety of tested workloads what saves storage space on larger
    server systems where perf.data size can easily reach several tens or
    even hundreds of GiBs, especially when profiling with DWARF-based
    stacks and tracing of context switches.

* perf record:

  Arnaldo Carvalho de Melo

  - Improve -user-regs/intr-regs suggestions to overcome errors.

* perf annotate:

  Jin Yao:

  - Remove hist__account_cycles() from callback, speeding up branch processing
    (perf record -b).

* perf stat:

  - Add a 'percore' event qualifier, e.g.: -e cpu/event=0,umask=0x3,percore=1/,
    that sums up the event counts for both hardware threads in a core.

    We can already do this with --per-core, but it's often useful to do
    this together with other metrics that are collected per hardware thread.

    I.e. now its possible to do this per-event, and have it mixed with other
    events not aggregated by core.

* arm64:

  Florian Fainelli:

  - Map Brahma-B53 CPUID to cortex-a53 events.

  - Add Cortex-A57 and Cortex-A72 events.

* csky:

  Mao Han:

  - Add DWARF register mappings for libdw, allowing --call-graph=dwarf to work
    on the C-SKY arch.

* x86:

  Andi Kleen/Kan Liang:

  - Add support for recording and printing XMM registers, available, for
    instance, on Icelake.

  Kan Liang:

  - Add uncore_upi (Intel's "Ultra Path Interconnect" events) JSON support.
    UPI replaced the Intel QuickPath Interconnect (QPI) in Xeon Skylake-SP.

* Intel PT:

  Adrian Hunter

  - Fix instructions sampling rate.

  - Timestamp fixes.

  - Improve exported-sql-viewer GUI, allowing, for instance, to copy'n'paste
    the trees, useful for e-mailing.

 Thanks,

	Ingo
