Subject[PATCH v2 0/3] perf arm-spe: Add snapshot mode support
Date
This patchset adds snapshot mode support for arm-spe.

- [PATCH 1/3] implements the minimal callbacks to support recording in
snapshot mode.
- [PATCH 2/3] implements the find_snapshot callback in order to handle
wrap-arounds in the AUX buffer.
- [PATCH 3/3] adds a test for spe snapshot mode.

---

Changes since v1:
- Added acme@kernel.org to the recipients list as I forgot to include
him in the original patchset [1].
- Removed [PATCH 1/5] and [PATCH 2/5] in order to keep patches
semantically relevant.
- Updated test script test_arm_spe.sh because it wasn't working on
distributions that use dash shell v0.5.10 (ubuntu 20) [2].
