DP link retraining causes (spurious?) underruns. We can't really avoid them, except perhaps by doing a full modeset (which has its own underrun suppression anyway). So let's just hide them. MST still has its own logic for retrainin, but a bigger hpd handling cleanup/unification is needed there anyway, so let's leave that be for now.

GMBUS is part of the display engine, and thus has no need for forcewake. Let's not bother trying to grab it then. I don't recall if the display engine suffers from system hangs due to multiple accesses to the same "cacheline" in mmio space. I hope not since we're no longer protected by the uncore lock since commit 4e6c2d58 ("drm/i915: Take forcewake once for the entire GMBUS transaction") Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: David Weinehall <david.weinehall@linux.intel.com> Signed-off-by:

Having skl_wm_level contain all of the watermarks for each plane is annoying since it prevents us from having any sort of object to represent a single watermark level, something we take advantage of in the next commit to cut down on all of the copy paste code in here. Changes since v1: - Style nitpicks - Fix accidental usage of i vs. PLANE_CURSOR - Split out skl_pipe_wm_active_state simplification into separate patch Signed-off-by:

Next part of cleaning up the watermark code for skl. This is easy, since it seems that we never actually needed to keep track of the linetime in the skl_wm_values struct anyway. Signed-off-by:

First part of cleaning up all of the skl watermark code. This moves the structures for storing the ddb allocations of each pipe into intel_crtc_state, along with moving the structures for storing the current ddb allocations active on hardware into intel_crtc. Changes since v1: - Don't replace alloc->start = alloc->end = 0; Signed-off-by:

I have re-ordered some struct members in patch: commit 44a655ca Author: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Date: Thu Oct 13 11:09:23 2016 +0100 drm/i915: Shrink cxsr_latency_table but that particular one is not initialized with named initializers which broke it. Move the bitfields back at the beginning. Space saving is still there. Signed-off-by:

Since "Dynamic page table allocations" were introduced, our page tables can grow (being dynamically allocated) with address space range usage. Unfortunately, their lifetime is bound to vm. This is not a huge problem when we're not using softpin - drm_mm is creating an upper bound on used range by causing addresses for our VMAs to eventually be reused. With softpin, long lived contexts can drain the system out of memory even with a single "small" object. For example: bo = bo_alloc(size); while(true) offset += size; exec(bo, offset); Will cause us to create new allocations until all memory in the system is used for tracking GPU pages (even though almost all PTEs in this vm are pointing to scratch). Let's free unused page tables in clear_range to prevent this - if no entries are used, we can safely free it and return this information to the caller (so that higher-level entry is pointing to scratch). v2: Document return value and free semantics (Joonas) v3: No newlines in vars block (Joonas) v4: Drop redundant local 'reduce' variable v5: Handle CI fail with enable_ppgtt=2 Cc: Michel Thierry <michel.thierry@intel.com> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Reviewed-by:Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Signed-off-by:

Let's use more top-down approach, where each gen8_ppgtt_clear_* function is responsible for clearing the struct passed as an argument and calling relevant clear_range functions on lower-level tables. Doing this rather than operating on PTE ranges makes the implementation of shrinking page tables quite simple. v2: Drop min when calculating num_entries, no negation in 48b ppgtt check, no newlines in vars block (Joonas) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Michel Thierry <michel.thierry@intel.com> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Signed-off-by:

We never used any invalid ptes, those were put in place for a possibility of doing gpu faults. However our batchbuffers are not restricted in length, so everything needs to be pointing to something and thus out-of-bounds is pointing to scratch. Remove the valid flag as it is always true. v2: Expand commit msg, patch reorder (Mika) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Michel Thierry <michel.thierry@intel.com> Reviewed-by:

Currently the display INIT power domain disabling/enabling happens in a mismatched way in the suspend/resume_early hooks respectively. This can leave display power wells incorrectly disabled in the resume hook if the suspend sequence is aborted for some reason resulting in the suspend/resume hooks getting called but the suspend_late/resume_early hooks being skipped. In particular this change fixes "Unclaimed read from register 0x1e1204" on BYT/BSW triggered from i915_drm_resume()-> intel_pps_unlock_regs_wa() when suspending with /sys/power/pm_test set to devices.

This patch introduces the vGPU workload scheduler routines. GVT workload scheduler is responsible for picking and executing GVT workload from current scheduled vGPU. Before the workload is submitted to host i915, the guest execlist context will be shadowed in the host GVT shadow context. the instructions in guest ring buffer will be copied into GVT shadow ring buffer. Then GVT-g workload scheduler will scan the instructions in guest ring buffer and submit it to host i915. Signed-off-by:
