ggtt_bind/unbind_vma already has checks for aliasing ppgtt or not, there's nothing else magic they do. Resurrect i915_ggtt_insert_entries to make the reuse possibel. Reviewed-by:

Currently we have the problem that the decision whether ptes need to be (re)written is splattered all over the codebase. Move all that into i915_vma_bind. This needs a few changes: - Just reuse the PIN_* flags for i915_vma_bind and do the conversion to vma->bound in there to avoid duplicating the conversion code all over. - We need to make binding for EXECBUF (i.e. pick aliasing ppgtt if around) explicit, add PIN_USER for that. - Two callers want to update ptes, give them a PIN_UPDATE for that. Of course we still want to avoid double-binding, but that should be taken care of: - A ppgtt vma will only ever see PIN_USER, so no issue with double-binding. - A ggtt vma with aliasing ppgtt needs both types of binding, and we track that properly now. - A ggtt vma without aliasing ppgtt could be bound twice. In the lower-level ->bind_vma functions hence unconditionally set GLOBAL_BIND when writing the ggtt ptes. There's still a bit room for cleanup, but that's for follow-up patches. v2: Fixup fumbles. v3: s/PIN_EXECBUF/PIN_USER/ for clearer meaning, suggested by Chris.

We load the ppgtt ptes once per gpu reset/driver load/resume and that's all that's needed. Note that this only blows up when we're using the allocate_va_range funcs and not the special-purpose ones used. With this change we can get rid of that duplication. Reviewed-by:

PIN_GLOBAL is set only when userspace asked for it, and that is only the case for the gen6 PIPE_CONTROL workaround. We're not allowed to just clear this. The important part of the fallback is to drop the restriction to the mappable range.

With the dynamic pagetable alloc code aliasing ppgtt special-cases where again mixed in all over the place with the low-level init code. Extract the va preallocation and clearing again into the common code where aliasing ppgtt gets set up. Note that with this we don't set the size of the aliasing ppgtt to the size of the parent ggtt address space. Which isn't required at all since except for the ppgtt setup/cleanup code no one ever looks at this. Reviewed-by:

Purpose of this tracking is to know when to flush the cache between the CPU and the non-coherent display engine. Prior to: commit 121920fa Author: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Date: Mon Mar 23 11:10:37 2015 +0000 drm/i915/skl: Query display address through a wrapper This worked by a mix of direct flag manipulation and checking for existence of a pinned GGTT VMA. With the introduction of rotated display mappings this approach is no longer correct. New simpler approach is to just keep this count over calls which pin and unpin objects to and from display, at the slight cost of extra space in every bo. (Inspired and extracted code from a larger rework by Chris Wilson.) v2: Remove the limit since it is not well defined. (Chris Wilson, Ville Syrjälä) v3: Commit message corrections.

The Displayport Link Layer Compliance Testing Specification 1.2 rev 1.1 specifies that repeated AUX transactions after a failure (no response / invalid response) must have a minimum delay of 400us before the resend can occur. Tests 4.2.1.1 and 4.2.1.2 are two tests that require this specifically. Also, the check for DP_AUX_CH_CTL_TIME_OUT_ERROR has been moved out into a separate case. This case just continues with the next iteration of the loop as the HW has already waited the required amount of time. V2: - Changed udelay() to usleep_range() V3: - Removed extraneous check for timeout - Updated comment to reflect this change V4: - Reformatted a comment V5: - Added separate check for HW timeout on AUX transactions. A message is logged upon detection of this case. V6: - Add continue statement to HW timeout detect case - Remove the log message indicating a timeout has been detected (review feedback) V7: - Updated the commit message to remove verbage about the HW timeout case that is no longer valid.

Not every DDIs is necessarily connected can be strapped off and, in the future, we'll have platforms with a different number of default DDI ports. So, let's only call intel_prepare_ddi_buffers() on DDI ports that are actually detected. We also use the opportunity to give a struct intel_digital_port to intel_prepare_ddi_buffers() as we'll need it in a following patch to query if the port supports HMDI or not. On my HSW machine this removes the initialization of a couple of (unused) DDIs. Signed-off-by:

Since the removal of the user pin_ioctl, the only means for pinning an object is either through binding to the scanout or during execbuf reservation. As the later prevents a call to set-tiling, we need only check if the obj is pinned into the display plane to see if we need reject the set-tiling ioctl. Signed-off-by:
