The Xe GPU health indicator is intended to fit into such reactive monitoring flows, where it could be used by management tools to fetch and update GPU health status. This patch adds Xe GPU health indicator support as a RAS feature. It introduces the health command IDs and request/response structures used by the System Controller mailbox, and integrates the feature into Xe through the gpu_health sysfs interface. The sysfs file, gpu_health, is created at the device level and provides a simple interface for observing and updating the reported GPU health state. It is exposed as read-only for non admin users while write access is only provided to the admin users. The sysfs file (gpu_health) is placed at the device level and behaves as follows: $ cat /sys/.../device/gpu_health ok $ echo critical > /sys/.../device/gpu_health $ cat /sys/.../device/gpu_health critical Userspace consumer (Level Zero Sysman): https://github.com/intel/compute-runtime/commit/3d974c6d9b65bede475c118e582761670ef110d2 Soham Purkait (1): drm/xe/xe_ras: Add RAS GPU health indicator .../ABI/testing/sysfs-driver-intel-xe-ras | 30 ++++ Documentation/gpu/xe/xe_device.rst | 7 + drivers/gpu/drm/xe/xe_ras.c | 146 ++++++++++++++++++ drivers/gpu/drm/xe/xe_ras_types.h | 57 +++++++ drivers/gpu/drm/xe/xe_sysctrl_mailbox_types.h | 4 + 5 files changed, 244 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-driver-intel-xe-ras -- 2.43.0
