[RFC,000/162] DG1 + LMEM enabling

Message

Matthew Auld Nov. 27, 2020, 12:04 p.m. UTC

This series includes a version of Maarten' series[1], which converts more of the
driver locking over to dma-resv. On top of this we now implement things like
LMEM eviction, which has a dependency on this new locking design.

In terms of new uAPI we have gem_create_ext, which offers extensions support for
gem_create. For now the only extension we add is 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. Note that the class/instance complexity in the uAPI is not very relevant
for DG1, but is in preparation for the Xe HP multi-tile architecture with
multiple memory regions.

The series still includes relocation support, but that's purely for CI, until we
have completed all the IGT rework[2] and so will not be merged. Likewise for
pread/pwrite, which will also be dropped from DG1+.
