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" # # * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (73 commits) # perf stat: Support 'percore' event qualifier # perf stat: Factor out aggregate counts printing # perf tools: Add a 'percore' event qualifier # perf docs: Add description for stderr # perf intel-pt: Fix sample timestamp wrt non-taken branches # perf intel-pt: Fix improved sample timestamp # perf intel-pt: Fix instructions sampling rate # perf regs x86: Add X86 specific arch__intr_reg_mask() # perf parse-regs: Add generic support for arch__intr/user_reg_mask() # perf parse-regs: Split parse_regs # perf vendor events arm64: Add Cortex-A57 and Cortex-A72 events #
