+Subject: [PATCH] Prefer Xe gtidle before fdinfo utilization
+
+The fdinfo collector walks /proc/*/fd and /proc/*/fdinfo on each sample.
+That is much more expensive than sysfs gtidle counters on process-heavy
+desktops. Prefer gtidle when the kernel exposes it, and keep fdinfo as a
+fallback for systems without gtidle.
