oprofile, x86: Add support for IBS branch target address reporting
This patch adds support for IBS branch target address reporting. A new
MSR (MSRC001_103B IBS Branch Target Address) has been added that
provides the logical address in canonical form for the branch
target. The size of the IBS sample that is transferred to the userland
has been increased.
For backward compatibility, the userland daemon must explicit enable
the feature by writing to the oprofilefs file
ibs_op/branch_target
After enabling branch target address reporting, the userland daemon
must handle the extended size of the IBS sample.
