drm/i915/selftests: Add a mock i915_vma to the mock_ring

2020-02-10T12:45:37+00:00

Add a i915_vma to the mock_engine/mock_ring so that the core code can always assume the presence of ring->vma.

drm/i915/gt: Pull context activation into central intel_context_pin()

2020-01-09T13:48:00+00:00

While this is encroaching on midlayer territory, having already made the state allocation a previous step in pinning, we can now pull the common intel_context_active_acquire() into intel_context_pin() itself. This is a prelude to make the activation a separate step inside pinning, outside of the ce->pin_mutex Signed-off-by: Chris Wilson Cc: Maarten Lankhorst Cc: Tvrtko Ursulin Reviewed-by: Maarten Lankhorst Link: https://patchwork.freedesktop.org/patch/msgid/20200109085717.873326-2-chris@chris-wilson.co.uk

drm/i915/gt: Discard stale context state from across idling

2020-01-03T11:26:01+00:00

Before we idle, on parking, we switch to the kernel context such that we have a scratch context loaded while the GPU idle, protecting any precious user state. Be paranoid and assume that the idle state may have been trashed, and reset the kernel_context image after idling.

drm/i915/gt: Pull GT initialisation under intel_gt_init()

2019-12-22T12:51:32+00:00

Begin pulling the GT setup underneath a single GT umbrella; let intel_gt take ownership of its engines! As hinted, the complication is the lifetime of the probed engine versus the active lifetime of the GT backends. We need to detect the engine layout early and keep it until the end so that we can sanitize state on takeover and release.

drm/i915/gt: Remove direct invocation of breadcrumb signaling

2019-12-18T17:11:28+00:00

Only signal the breadcrumbs from inside the irq_work, simplifying our interface and calling conventions. The micro-optimisation here is that by always using the irq_work interface, we know we are always inside an irq-off critical section for the breadcrumb signaling and can ellide save/restore of the irq flags.
