Driver Changes: - Prepare for local/device memory support on DG1 by starting to use it for kernel internal allocations: context, ring and engine scratch (Matt A, CQ, Abdiel, Imre) - Sandybridge fix to avoid hard hang on ring resume (Chris) - Limit imported dma-buf size to int32 (Matt A) - Double check heartbeat timeout before resetting (Chris) - Use new tasklet API for execution list (Emil) - Fix SPDX checkpats warnings (Chris) - Fixes for various checkpatch warnings (Chris) - Selftest improvements (Chris) - Move the defer_request waiter active assertion to correct spot (Chris) - Make local-memory probing a GT operation (Matt, Tvrtko) - Protect against request freeing during cancellation on wedging (Chris) - Retire unexpected starting state error dumping (Chris) - Distinction of memory regions in debugging (Zbigniew) - Always flush the submission queue on checking for idle (Chris) - Consolidate 2big error check to helper (Matt) - Decrease number of subplatform bits (Tvrtko) - Remove unused internal request priority levels (Chris) - Document the unused internal header bits in buddy allocator (Matt) - Cleanup the region class/instance encoding (Matt) Signed-off-by: Dave Airlie <airlied@redhat.com> From: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/YGxksaZGXHnFxlwg@jlahtine-mobl.ger.corp.intel.com
