[Intel-gfx] [PATCH 2/2] drm/i915/execlists: Reset RING registers upon resume

There is a disparity in the context image saved to disk and our own bookkeeping - that is we presume the RING_HEAD and RING_TAIL match our stored ce->ring->tail value. However, as we emit WA_TAIL_DWORDS into the ring but may not tell the GPU about them, the GPU may be lagging behind our

[Intel-gfx] [PATCH 1/2] drm/i915: Only shrink the unbound objects during freeze

At the point of creating the hibernation image, the runtime power manage core is disabled - and using the rpm functions triggers a warn. i915_gem_shrink_all() tries to unbind objects, which requires device access and so tries to how an rpm reference triggering a warning: [ 44.235420]

[Intel-gfx] [PATCH v7 1/6] drm/i915: Fallback to lower link rate and lane count during link training

According to the DisplayPort Spec, in case of Clock Recovery failure the link training sequence should fall back to the lower link rate followed by lower lane count until CR succeeds. On CR success, the sequence proceeds with Channel EQ. In case of Channel EQ failures, it should fallback to lower
