[email protected] changed: What |Removed |Added ---------------------------------------------------------------------------- Platform|Other |CachyOS Version First|6.6.2 |6.7.2 Reported In| | --- Comment #1 from [email protected] --- Confirming this also affects xe-driver iGPUs, not just discrete Arc cards — same root cause, different hardware class. System: Intel Core Ultra 9 288V (Lunar Lake), Arc 130V/140V iGPU KDE Plasma 6.7.2, Frameworks 6.27.0, Qt 6.11.1, kernel 7.1.3-1-cachyos, xe driver journalctl confirms the same failure mode: ksystemstats[PID]: "Device directory \"/sys/bus/event_source/devices/i915\" does not exist\n" The actual xe PMU device is present on this system at: /sys/bus/event_source/devices/xe_0000_00_02.0 Ruled out permissions as a factor — cap_perfmon is correctly set on ksystemstats_intel_helper (getcap confirms cap_perfmon=ep) and kernel.perf_event_paranoid=2. The helper fails before reaching that stage because it checks the i915 path first and exits early when it's not found, rather than falling back to checking for an xe* device. Given this now confirmed on both a discrete Arc card (A380) and an iGPU (Lunar Lake 130V/140V), this looks like a straightforward "helper only checks i915, needs an xe* fallback path" fix rather than anything platform-specific — should affect every xe-driver system uniformly (Lunar Lake, Arrow Lake, Battlemage, Alchemist-on-xe). -- You are receiving this mail because: You are watching all bug changes.
