What: /sys/bus/pci/drivers/xe/.../cper_on_query Date: October 2026 KernelVersion: 7.5 Contact: intel-xe@lists.freedesktop.org Description: This file controls whether a CPER (Common Platform Error Record) is emitted each time a RAS error counter is queried. This sysfs file is present only on Intel Xe platforms that support the RAS error counter interface and when the kernel is built with CPER support. Reading the current setting is available to all users, while updating it is restricted to administrative users only. The value is a boolean. When set to 1, every counter query emits a CPER record built from the counter and its associated info queue data. When set to 0 (default), no record is emitted on query.
