+=========================
+I915 DG1/LMEM RFC Section
+=========================
+
+Upstream plan
+=============
+For upstream the overall plan for landing all the DG1 stuff and turning it for
+real, with all the uAPI bits is:
+
+* Merge basic HW enabling of DG1(still without pciid)
+* Merge the uAPI bits behind special CONFIG_BROKEN(or so) flag
+ * At this point we can still make changes, but importantly this lets us
+ start running IGTs which can utilize local-memory in CI
+* Convert over to TTM, make sure it all keeps working. Some of the work items:
+ * TTM shrinker for discrete
+ * dma_resv_lockitem for full dma_resv_lock, i.e not just trylock
+ * Use TTM CPU pagefault handler
+ * Route shmem backend over to TTM SYSTEM for discrete
+ * TTM purgeable object support
+ * Move i915 buddy allocator over to TTM
+* Send RFC(with mesa-dev on cc) for final sign off on the uAPI
+* Add pciid for DG1 and turn on uAPI for real
