Let’s establish a merge plan for Xe, by writing down clear pre-merge goals, in
order to avoid unnecessary delays.
This initial document starts with a TODO list containing items with clear and
measurable key results. Xe’s initial pull request should only be sent to
dri-devel after all the items are clearly resolved.
Since many of them involve some level of a community consensus, in many cases,
the consensus will be reached in follow-up patches to this document with more
details of the API or helpers that will be developed or modified.
Besides of the items that are highlighted in this document, it is important
to highlight that Oded, has been volunteered to give the overall ack on Xe
driver as the way to confirm that it looks good for upstream.
v2: Incorporated Daniel's feedback:
- Do not make long-running compute a blocker.
- Add a mention to drm-exec that that ties to vm_bind and long-running
compute jobs. Then I also added GPUVA since I recently noticed that this
ties also to the work Matt is doing on that front.
- Added the devcoredump section.
- Add the mention to Oded being volunteered for the overall ack.
v3: Reword a bit the Async VM_BIND to incorporate Daniel's feedback on ensuring
the async vmbind consensus explicitly include Mesa, besides other kernel
drivers.

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.
