# Merge: a13f950ef13f 62e1c09418fc
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Sun May 19 11:20:22 2019 -0700
# 
#     Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull perf tooling updates from Ingo Molnar:
#      "perf.data:
#     
#        - 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:
#     
#        - Improve -user-regs/intr-regs suggestions to overcome errors
#     
#       perf annotate:
#     
#        - 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:
#     
#        - Map Brahma-B53 CPUID to cortex-a53 events.
#     
#        - Add Cortex-A57 and Cortex-A72 events.
#     
#       csky:
#     
#        - Add DWARF register mappings for libdw, allowing --call-graph=dwarf
#          to work on the C-SKY arch.
#     
#       x86:
#     
#        - Add support for recording and printing XMM registers, available,
#          for instance, on Icelake.
#     
#        - Add uncore_upi (Intel's "Ultra Path Interconnect" events) JSON
#          support. UPI replaced the Intel QuickPath Interconnect (QPI) in
#          Xeon Skylake-SP.
#     
#       Intel PT:
#     
#        - Fix instructions sampling rate.
#     
#        - Timestamp fixes.
#     
#        - Improve exported-sql-viewer GUI, allowing, for instance, to
#          copy'n'paste the trees, useful for e-mailing"
#
