Thanks for bringing up this, Arnaldo! Just remind, James sent the latest series is v8 [1] couple weeks ago, and I confirmed v8 can apply clearly on the latest mainline kernel. We need kernel maintainers' review so can move forward. Thanks, Leo [1] https://lore.kernel.org/linux-arm-kernel/20250901-james-perf-feat_spe_eft-v8-0-2e2738f24559@linaro.org/
