This is Lucas' DG1 enabling series[1], plus some of the DG1 specific enablers for supporting LMEM on top, including some bits of new uAPI.
Posting this series as RFC to get feedback while we continue to work on adapting the code to use DMA reservation incrementally. This is currently WIP[2][3]. In terms of new uAPI we have gem_create_ext, which offers extensions support for gem_create, this includes giving userspace the ability to optionally provide a priority list of potential placements for the object. The other bit of new uAPI is the query interface for memory regions, which describes the supported memory regions for the device. What this reports can then be fed into gem_create_ext to specify where an object might reside, like device local memory.
