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. r~
