Add i915 changes on top of the fixes proposed at https://lore.kernel.org/all/20241008183501.1354695-1-lucas.demarchi@xxxxxxxxx/ First patch is the patches needed from that series, squashed to avoid reviewing them here and multiple versions. Second and third patches fix the issues with i915 unbind. The rest are "nice to have refactors/cleanups". This series went through the sames bind/unbind tests as they dummy_pmu. I do get some warnings, but none related to PMU - they are related with other parts of i915 not behaving correctly on fast bind/unbind sequences: - i915 0000:03:00.0: [drm] *ERROR* Failed to setup i915 fbdev emulation (ret=-512) and - RIP: 0010:drm_mode_config_cleanup+0x2f4/0x310 [drm] Lucas De Marchi (8): squashed series - 20241008183501.1354695-1-lucas.demarchi@xxxxxxxxx drm/i915/pmu: Let resource survive unbind drm/i915/pmu: Fix crash due to use-after-free drm/i915/pmu: Rename cpuhp_slot to cpuhp_state drm/i915/pmu: Stop setting event_init to NULL drm/i915/pmu: Replace closed with registered drm/i915/pmu: Remove pointless synchronize_rcu() call drm/i915/pmu: Release open events when unregistering drivers/gpu/drm/i915/i915_pmu.c | 129 +++++++++++++++++++++----------- drivers/gpu/drm/i915/i915_pmu.h | 10 ++- include/linux/perf_event.h | 12 +++ kernel/events/core.c | 37 +++++++-- 4 files changed, 137 insertions(+), 51 deletions(-) -- 2.47.0
