[Intel-gfx] [PATCH] drm/i915/gem: Early rejection of no-aperture map_ggtt

[Joonas Lahtinen]

Quoting Chris Wilson (2019-11-05 16:53:05)
> If the device does not have an aperture through which we can indirectly
> access and detile the buffers, simply reject the ioctl. Later we can
> extend the ioctl to support different modes, but as an extension the
> user must opt in and explicitly control the mmap type (viz
> MMAP_OFFSET_IOCTL).
