During driver init we may not have a valid framebuffer for the primary plane even though the plane is enabled due to failed BIOS fb takeover. This means we have to avoid dereferencing the fb in .update_primary_plane() when disabling the plane. The introduction of the primary plane rotation in commit d91a2cb8e5104233c02bbde539bd4ee455ec12ac Author: Sonika Jindal <sonika.jindal@intel.com> Date: Fri Aug 22 14:06:04 2014 +0530 drm/i915: Add 180 degree primary plane rotation support caused a regression by trying to look up the pixel format before we can be sure there's a valid fb available. This isn't entirely unsurprising since the rotation patches originally predate the change to the primary plane code that calls .update_primary_plane() also when disabling the plane: commit fdd508a6 Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Fri Aug 8 21:51:11 2014 +0300 drm/i915: Call .update_primary_plane in intel_{enable, disable}_primary_hw_plane() v2: Warn but don't blow up when trying to enable a plane w/o an fb (Chris) Cc: Sonika Jindal <sonika.jindal@intel.com> Signed-off-by:Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

The workarounds that are applied are exported to a debugfs file; this is used to verify their state after the test case (reset or suspend/resume etc). This patch is only required to support i-g-t. Signed-off-by:

For BDW workarounds are currently initialized in init_clock_gating() but they are lost during reset, suspend/resume etc; this patch moves the WAs that are part of register state context to render ring init fn otherwise default context ends up with incorrect values as they don't get initialized until init_clock_gating fn. v2: Add workarounds to golden render state This method has its own issues, first of all this is different for each gen and it is generated using a tool so adding new workaround and mainitaining them across gens is not a straightforward process. v3: Use LRIs to emit these workarounds (Ville) Instead of modifying the golden render state the same LRIs are emitted from within the driver. v4: Use abstract name when exporting gen specific routines (Chris) For: VIZ-4092 Signed-off-by:

According to spec FBC on BDW and HSW are identical without any gaps. So let's copy the nuke and let FBC really start compressing stuff. Without this patch we can verify with false color that nothing is being compressed. With the nuke in place and false color it is possible to see false color debugs. Unfortunatelly on some rings like BCS on BDW we have to avoid Bits 22:18 on LRIs due to a high risk of hung. So, when using Blt ring for frontbuffer rend cache would never been cleaned and FBC would stop compressing buffer. One alternative is to cache clean on software frontbuffer tracking. v2: Fix rebase conflict. v3: Do not clean cache on BCS ring. Instead use sw frontbuffer tracking. Signed-off-by:

Previously, it was possible for the GPU memory accesses to be swizzled to try to optimize the fetches for tiled buffers. This swizzling was on top of what the memory controller in the uncore already does. With broadwell, we drop that GPU side swizzling, and the corresponding initialization in 3 units (GAM, GT, DE). All those bits are reserved, as specs put it: Before Gen8, there was a historical configuration control field to swizzle address bit[6] for in X/Y tiling modes. This was set in three different places: TILECTL[1:0], ARB_MODE[5:4], and DISP_ARB_CTL[14:13]" For Gen8 the swizzle fields are all reserved, and the CPU's memory controller performs all address swizzling modifications. This also means that user space doesn't have to manually swizzle when accessing tiled buffers from the CPU, and so we always return I915_BIT_6_SWIZZLE_NONE from i915_gem_detect_bit_6_swizzle(), which short-circuits the initialization of the registers mentionned above in i915_gem_init_swizzling(). v2: Refine the explanation a bit more (Daniel) v3: Make it BDW+ specific (Steve) Cc: Steve Aarnio <steve.j.aarnio@linux.intel.com> Signed-off-by:

On BDW we're seeing a problem that after we runtime resume, the outputs connected to DDI C are not detected: they don't appear in the SDEISR register and GMBUS transactions don't work. They stop working at the moment we call intel_opregion_notify_adapter() during runtime suspend, but they don't go back to work when we call the same function during runtime resume. They only work after we do a modeset and call intel_opregion_notify_encoder(), but this point is already too late. While debugging, I tried to pass PCI_D3hot which is the value that matches the spec, and it seems to have solved the problem. I couldn't find any explanation of why this solves the problem, but there's also no documented explanation - besides our code and git log - of why Haswell should use PCI_D1, so keep this for now in order to keep BDW runtime PM working. Also add a comment to point the fact that there's no spec documenting all the weirdness involved here.

Unfortunately, the gem_obj/vma relationship is not symmetrical; a gem_obj can look up for the same vma more than once (where the ppgtt refcount is incremented), but will free the vma only once (i915_gem_free_object). This difference in refcount get/put means that the ppgtt is not removed after the context and vma are destroyed, because sometimes the refcount will never go back to zero. v2: Just move the ppgtt refcount into vma_create.

Since the ringbuffer does not belong per engine anymore, we have to make sure that we are always recording the correct ringbuffer. TODO: This is only a small fix to keep basic error capture working, but we need to add more information for it to be useful (e.g. dump the context being executed). v2: Reorder how the ringbuffer is chosen to clarify the change and rename the variable, both changes suggested by Chris Wilson.

For cleanliness, i915_error_object_create() was written to handle the NULL pointer in a central location. The macro that wrapped it and passed it a num_pages to use, was not safe. As we now never limit the num_pages to use (we did so at one point to only capture the first page of the context), we can remove the redundant macro and be NULL safe again. Signed-off-by:
