Issue between evdi and Lunar Lake's xe: evdi: [W] evdi_gem_mmap:490 Don't allow imported objects to be mapped: owner: xe

[KaylorDave]

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)

Can you check this with recently released evdi-1.14.14?
There were some performance improvements for this platform.

Hi this is still happening and I think I was already on evdi 1.14.14:

evdi is already the newest version (1.14.14-178)
