[Intel-gfx] [PATCH 0/1] drm: Add a gpu page-table walker

[Thomas Hellström]

A slightly unusual cover letter for a single patch.

The page table walker is currently used by the xe driver only,
but the code is generic so we can be good citizens and add it to drm
as a helper, for possible use by other drivers,
If so we can merge the commit when we merge the xe driver.

The question raised here is
*) Should it be a generic drm helper or xe-specific with changed
   prefixes?
*) If a drm helper, should we use a config option?

For usage examples, see xe_pt.c
https://gitlab.freedesktop.org/drm/xe/kernel/-/blob/drm-xe-next/drivers/gpu/drm/xe/xe_pt.c

Thanks,
Thomas
