[PATCH 0/7] [CI] Enable GuC submission by default on DG1

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

Minimum set of patches to enable GuC submission on DG1 and enable it by
default.

A little difficult to test as IGTs do not work with DG1 due to a bunch
of uAPI features being disabled (e.g. relocations, caching memory
options, etc...). Hence extra patches at the end to enable some
features / add debugging info.

[PATCH 1/7] drm/i915: Do not define vma on stack

[John.C.Harrison]

From: Venkata Sandeep Dhanalakota <venkata.s.dhanalakota@intel.com>

Defining vma on stack can cause stack overflow, if
vma gets populated with new fields.

[PATCH 2/7] drm/i915/guc: put all guc objects in lmem when available

[John.C.Harrison]

From: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com>

The firmware binary has to be loaded from lmem and the recommendation is
to put all other objects in there as well. Note that we don't fall back
to system memory if the allocation in lmem fails because all objects are
allocated during driver load and if we have issues with lmem at that point
something is seriously wrong with the system, so no point in trying to
handle it.

[Intel-gfx] [PATCH 2/7] drm/i915/guc: put all guc objects in lmem when available

[John.C.Harrison]

From: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com>

The firmware binary has to be loaded from lmem and the recommendation is
to put all other objects in there as well. Note that we don't fall back
to system memory if the allocation in lmem fails because all objects are
allocated during driver load and if we have issues with lmem at that point
something is seriously wrong with the system, so no point in trying to
handle it.
