GPU RFC Section
===============
For complex work, especially new uapi, it is often good to nail the high level
design issues before getting lost in the code details. This section is meant to
host such documentation:
* Each RFC should be a section in this file, explaining the goal and main design
considerations. Especially for uapi make sure you Cc: all relevant project
mailing lists and involved people outside of dri-devel.
* For uapi structures add a file to this directory with and then pull the
kerneldoc in like with real uapi headers.
* Once the code has landed move all the documentation to the right places in
the main core, helper or driver sections.
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 Signed-off-by: Matthew Auld <matthew.auld@intel.com> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Thomas Hellström <thomas.hellstrom@linux.intel.com> Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Lionel Landwerlin <lionel.g.landwerlin@linux.intel.com> Cc: Jon Bloomfield <jon.bloomfield@intel.com> Cc: Jordan Justen <jordan.l.justen@intel.com> Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Kenneth Graunke <kenneth@whitecape.org> Cc: Jason Ekstrand <jason@jlekstrand.net> Cc: Dave Airlie <airlied@gmail.com> Cc: dri-devel@lists.freedesktop.org Cc: mesa-dev@lists.freedesktop.org Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Dave Airlie <airlied@redhat.com> Acked-by: Kenneth Graunke <kenneth@whitecape.org> Acked-by: Jon Bloomfield <jon.bloomfield@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210429103056.407067-1-matthew.auld@intel.com

drm/doc: add rfc section for small BAR uapi Add an entry for the new uapi needed for small BAR on DG2+. v2: - Some spelling fixes and other small tweaks. (Akeem & Thomas) - Rework error capture interactions, including no longer needing NEEDS_CPU_ACCESS for objects marked for capture. (Thomas) - Add probed_cpu_visible_size. (Lionel) v3: - Drop the vma query for now. - Add unallocated_cpu_visible_size as part of the region query. - Improve the docs some more, including documenting the expected behaviour on older kernels, since this came up in some offline discussion. v4: - Various improvements all over. (Tvrtko) v5: - Include newer integrated platforms when applying the non-recoverable context and error capture restriction.
