This series introduces device wedged event in DRM subsystem and uses it in xe and i915 drivers. Detailed description in commit message. This was earlier attempted as xe specific uevent in v1 and v2. https://patchwork.freedesktop.org/series/136909/ Similar work by André Almeida. https://lore.kernel.org/dri-devel/20221125175203.52481-1-andrealmeid@igalia.com/ v2: Change authorship to Himal (Aravind) Add uevent for all device wedged cases (Aravind) v3: Generic re-implementation in DRM subsystem (Lucas) v4: s/drm_dev_wedged/drm_dev_wedged_event Use drm_info() (Jani) Kernel doc adjustment (Aravind) Change authorship to Raag (Aravind) v5: Send recovery method with uevent (Lina) Expose supported recovery methods via sysfs (Lucas) v6: Access wedge_recovery_opts[] using helper function (Jani) Use snprintf() (Jani) v7: Convert recovery helpers into regular functions (Andy, Jani) Aesthetic adjustments (Andy) Handle invalid method cases Add documentation to drm-uapi.rst (Sima) v8: Drop sysfs and allow sending multiple methods with uevent (Lucas, Michal) Improve documentation (Christian, Rodrigo) static_assert() globally (Andy) v9: Document prerequisites section (Christian) Provide 'none' method for reset cases (Christian) Provide recovery opts using switch cases v10: Clarify mmap cleanup and consumer prerequisites (Christian, Aravind) Raag Jadav (4): drm: Introduce device wedged event drm/doc: Document device wedged event drm/xe: Use device wedged event drm/i915: Use device wedged event Documentation/gpu/drm-uapi.rst | 112 +++++++++++++++++++++++++- drivers/gpu/drm/drm_drv.c | 66 +++++++++++++++ drivers/gpu/drm/i915/gt/intel_reset.c | 3 + drivers/gpu/drm/xe/xe_device.c | 9 ++- include/drm/drm_device.h | 8 ++ include/drm/drm_drv.h | 1 + 6 files changed, 194 insertions(+), 5 deletions(-)
