drm/doc/rfc: i915 DG1 uAPI
Add an entry for the new uAPI needed for DG1. Also add the overall
upstream plan, including some notes for the TTM conversion.
v2(Daniel):
- include the overall upstreaming plan
- add a note for mmap, there are differences here for TTM vs i915
- bunch of other suggestions from Daniel
v3:
(Daniel)
- add a note for set/get caching stuff
- add some more docs for existing query and extensions stuff
- add an actual code example for regions query
- bunch of other stuff
(Jason)
- uAPI change(!):
- try a simpler design with the placements extension
- rather than have a generic setparam which can cover multiple
use cases, have each extension be responsible for one thing
only
v4:
(Daniel)
- add some more notes for ttm conversion
- bunch of other stuff
(Jason)
- uAPI change(!):
- drop all the extra rsvd members for the region_query and
region_info, just keep the bare minimum needed for padding
v5:
(Jason)
- for the upstream plan, add a requirement that we send the uAPI bits
again for final sign off before turning it on for real
- document how we intend to extend the rsvd bits for the region query
(Kenneth)
- improve the comment for the smem+lmem mmap mode and caching
