Revision 6ba5b613837c5d997ad8297b22fc46cd0be58d76 authored by Alex Deucher on 09 November 2023, 20:31:00 UTC, committed by Alex Deucher on 17 November 2023, 05:58:20 UTC
Add a module parameter to control the AGP aperture. The AGP aperture is an aperture in the GPU's internal address space which provides direct non-paged access to the platform address space. This access is non-snooped so only uncached memory can be accessed. Add a knob so that we can toggle this for debugging.
