This reorg is breaking PMU-EBB tests, unfortunately. These tests are run from
the kernel
tree [1] and I test them inside a pSeries TCG guest. You'll need to apply
patches 9 and
10 of [2] beforehand (they apply cleanly in current master) because they aren't
upstream
yet and EBB needs it.
The tests that are breaking consistently with this reorg are:
back_to_back_ebbs_test.c
cpu_event_pinned_vs_ebb_test.c
cycles_test.c
task_event_pinned_vs_ebb_test.c
In which case perhaps drop my first patch for now, and instead simply replicate
your tcg algorithm in c exactly -- using none of the helpers that currently
exist.
We can improve the code, and the use of pmc_get_event from
hreg_compute_hregs_value second.
