Issue between evdi and Lunar Lake's xe: evdi: [W] evdi_gem_mmap:490 Don't allow imported objects to be mapped: owner: xe #554
Description
Environment:
- Intel Core Ultra (Lunar Lake) with Intel Arc Graphics [8086:64a0]
- Kernel 6.14.0-37-generic
- Ubuntu 24.04
- xe driver
- HP USB-C/A Universal Dock G2 (DisplayLink-based)
- Two 2560x1440@60Hz external monitors
Impact:
- Choppy/stuttery display output on external monitors
- High CPU usage from DisplayLinkManager (~16% on average, saw spikes that consumed an entire core)
- Same dock works smoothly on older laptops using i915 driver (e.g., HP EliteBook 840 G8)
