 5Upstream plan
 6=============
 7For upstream the overall plan for landing all the DG1 stuff and turning it for
 8real, with all the uAPI bits is:
 9
10* Merge basic HW enabling of DG1(still without pciid)
11* Merge the uAPI bits behind special CONFIG_BROKEN(or so) flag
12        * At this point we can still make changes, but importantly this lets us
13          start running IGTs which can utilize local-memory in CI
14* Convert over to TTM, make sure it all keeps working. Some of the work items:
15        * TTM shrinker for discrete
16        * dma_resv_lockitem for full dma_resv_lock, i.e not just trylock
17        * Use TTM CPU pagefault handler
18        * Route shmem backend over to TTM SYSTEM for discrete
19        * TTM purgeable object support
20        * Move i915 buddy allocator over to TTM
21* Send RFC(with mesa-dev on cc) for final sign off on the uAPI
22* Add pciid for DG1 and turn on uAPI for real
