[Intel-gfx] [PATCH] drm/i915/gt: Add a comment about how to use udev for configuring engines

[Chris Wilson]

We expose engine properties under sysfs so that the sysadmin can
configure the driver according to their requirements. We can also use
udev rules to then apply that configuration anytime a device is
reloaded. Include a udev snippet provided by Joonas as an example.

+ * The sysfs provides a means for configuring each engine for the intended
+ * usecase, and by utilising a udev the configuration can be made persistent
+ * across reboots and device unbinding.
+ *
+ * An example udev rule to run a custom sysadmin script would be,
+ * /etc/udev/rules.d/50-intel-gpu.rules:
+ *
+ * ACTION=="bind|add",SUBSYSTEM=="pci",DRIVER=="i915",RUN+="/usr/local/libexec/setup-intel-gpu.sh"
+ *
+ * where the script receives the device name and can open the sysfs, e.g.:
+ * for ENGINE in $(find /sys/$DEVPATH/drm/card?/engine -maxdepth 1) do
+ *   echo 0 > $ENGINE/heartbeat_interval_ms # Disable hang checking
+ * done

If we just could get this into the output of 'make htmldocs', it would
be good.

[Intel-gfx] [PATCH] drm/i915/gt: Add a comment about how to use udev for configuring engines

[Chris Wilson]

We expose engine properties under sysfs so that the sysadmin can
configure the driver according to their requirements. We can also use
udev rules to then apply that configuration anytime a device is
reloaded. Include a udev snippet provided by Joonas as an example.

v2: Update the snippet
