Hi, Maybe I should not send patches this late at night as I end up messing things up and spamming sleeping people. Sorry for this version 4. The real fix is in patch 2. The rest is a helper that adds the with_intel_gt_pm_if_awake() (from Chris) and one more check on the status of the engine before accessing it for clearing the TLB. Andi Changelog ========= v3 -> v4 - Fix e-mail mismatch in author and in SoB (Sorry!). v2 -> v3 (v2: https://patchwork.freedesktop.org/series/103835/) - Add missing header file that was causing a compmile error. - Fix wrong patch formatting. v1 -> v2 (v1: https://patchwork.freedesktop.org/series/103831/) - Add with_intel_gt_pm_if_awake() macro for gt specific wakeref. - Check if an engine is awake before invalidating its TLB.
