Hi Arnaldo,

Can you please take a look at applying this series? Its kernel-side dependent series has already been applied and is in Linus' master.

Thanks,

Kim

Hello Linux perf tools users and maintainers,

The first patch in this series prepares the perf tool to support
retrieving cpuid and pmu_mappings data when in report mode,
information that is needed to accurately decode IBS data.

The second patch adds a header file tools/arch/x86/include/asm/amd-ibs.h
from a separate kernel-side submittion [1].

The third patch allows the tool to print a textual representation
of the sample data recorded by IBS.
