Add a sysfs interface that reports the current GPU health state and lets admin users and management tools update it but is readable by all users. Requests are routed through the sysctrl mailbox. The interface is 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 critical Signed-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.com Signed-off-by: Riana Tauro <riana.tauro@intel.com>
