2020-07-08drm/i915: Introduce gt_init_mmioDaniele Ceraolo Spurio
We already call 2 gt-related init_mmio functions in driver_mmio_probe and a 3rd one will be added by a follow-up patch, so pre-emptively introduce a gt_init_mmio function to group them.

2020-07-08drm/i915: Move the engine mask to intel_gt_infoDaniele Ceraolo Spurio
Since the engines belong to the GT, move the runtime-updated list of available engines to the intel_gt struct. The original mask has been renamed to indicate it contains the maximum engine list that can be found on a matching device. In preparation for other info being moved to the gt in follow up patches (sseu), introduce an intel_gt_info structure to group all gt-related runtime info. v2: s/max_engine_mask/platform_engine_mask (tvrtko), fix selftest Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Cc: Andi Shyti <andi.shyti@intel.com> Cc: Venkata Sandeep Dhanalakota <venkata.s.dhanalakota@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> #v1 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20200708003952.21831-5-daniele.ceraolospurio@intel.com
2020-07-06drm/i915: Reboot CI if we get wedged during driver initMichał Winiarski
Getting wedged device on driver init is pretty much unrecoverable. Since we're running various scenarios that may potentially hit this in CI (module reload / selftests / hotunplug), and if it happens, it means that we can't trust any subsequent CI results, we should just apply the taint to let the CI know that it should reboot (CI checks taint between test runs). v2: Comment that WEDGED_ON_INIT is non-recoverable, distinguish WEDGED_ON_INIT from WEDGED_ON_FINI (Chris) v3: Appease checkpatch, fixup search-replace logic expression mindbomb in assert (Chris) Signed-off-by: Michał Winiarski <michal.winiarski@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Petri Latvala <petri.latvala@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20200706144107.204821-1-michal@hardline.pl
