[PATCH 0/1] perf test: Add test for branch stack sampling

[German Gomez <german.gomez@arm.com>]

Hi,

While testing Anshuman Khandual's branch stack sampling ABI, and BRBE
driver ([1] and [2] respectively) I've been using this test to check the
consistency between arches (x86 and Arm64).

We might extend it with Arm64-specific tests once the BRBE driver has
been reviewed and merged, but for now I think this is generic enough to
cover both x86 LBR and Arm BRBE.

Thanks,
German
