Requests are routed through the sysctrl mailbox. The interfaceis present only on platforms that support the GPU health indicator.The interface is a single read/write file at the device level: $ cat /sys/.../device/gpu_health ok $ echo critical > /sys/.../device/gpu_health $ cat /sys/.../device/gpu_health criticalSigned-off-by: Soham Purkait <soham.purkait@intel.com>Acked-by: Rodrigo Vivi <rodrigo.vivi@intel.com>Acked-by: Raag Jadav <raag.jadav@intel.com>Reviewed-by: Andi Shyti <andi.shyti@linux.intel.com>Reviewed-by: Badal Nilawar <badal.nilawar@intel.com>Link: https://patch.msgid.link/20260716073600.674089-4-soham.purkait@intel.comSigned-off-by: Riana Tauro <riana.tauro@intel.com> List of files: /linux/Documentation/ABI/testing/sysfs-driver-intel-xe-ras Thu, 16 Jul 2026 09:36:02 +0200 Soham Purkait <soham.purkait@intel.com>
