[PATCH] drm/xe: Move IRQ-related registers to dedicated header

Matt Roper matthew.d.roper at intel.com
Mon Sep 23 21:45:11 UTC 2024


IRQ registers have a well-defined scope and make sense to collect in a
dedicated header file.  This also reduces confusion about the GT IRQ
registers --- even though those registers relate to the GTs, they
actually live outside the GT (in the sgunit) and thus do not need to
worry about GT-specific register concepts like forcewake, steering, etc.
