The intel_dp_autotest_video_pattern() function gets invoked through the compliance test handler on a HPD short pulse if the test type is set to DP_TEST_VIDEO_PATTERN. This performs the DPCD registers reads to read the requested test pattern, video pattern resolution, frame rate and bits per color value. The results of this analysis are handed off to userspace so that the userspace app can set the video pattern mode appropriately for the test result/response. When the test is requested with specific BPC value, we read the BPC value from the DPCD register. If this BPC value in intel_dp structure has a non-zero value and we're on a display port connector, then we use the value to calculate the bpp for the pipe. Also in this case if its a 18bpp video pattern request, then we force the dithering on pipe to be disabled since it causes CRC mismatches. The compliance_test_active flag is set at the end of the individual test handling functions. This is so that the kernel-side operations can be completed without the risk of interruption from the userspace app that is polling on that flag. v5: * Remove test_result variable * Populate the compliance test data at the end of the function (Jani Nikula) v4: *Return TEST_NAK on read failures and invalid values (Jani Nikula) * Address CRC mismatch errors v3: * Use the updated properly shifted bit definitions (Jani Nikula) * Force dithering to be disabled on 18bpp compliance test request (Manasi Navare) v2: * Updated the DPCD Register reads based on proper defines in header (Jani Nikula) * Squahsed the patch that forced the pipe bpp to compliance test bpp (Jani Nikula) Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1485274909-17470-1-git-send-email-manasi.d.navare@intel.com

This patch adds support to handle automated DP compliance link training test requests. This patch has been tested with Unigraf DPR-120 DP Compliance device for testing Link Training Compliance. After we get a short pulse Compliance test request, test request values are read and hotplug uevent is sent in order to trigger another modeset during which the pipe is configured and link is retrained and enabled for link parameters requested by the test. v5: * Only modify the compliance structure after all validation is done (Jani Nikula) * Remove the variable test_result (Jani Nikula) v4: * Return TEST_NAK for read failures and invalid values (Jani Nikula) * Conver the test link BW to link rate before storing (Jani Nikula) v3: * Validate the test link rate and lane count as soon as the request comes (Jani Nikula) v2: * Validate the test lane count before using it in intel_dp_compute_config (Jani Nikula) Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1485274594-17361-1-git-send-email-manasi.d.navare@intel.com

Along with GLK it was introduced the .is_lp and IS_GEN9_LP. So, following the same simplification standard we can put Skylake and Kabylake under the same bucket for most of the things. So let's add the IS_GEN9_BC for "Big Core" (non Atom based platforms). The i915_drv.c was let out of this patch on purpose because that is really a decision per platform, just like other cases where IS_KABYLAKE is different from IS_SKYLAKE. v2: fix conflict with IS_LP and 3 new cases for this big core bucket: - intel_ddi.c: intel_ddi_get_link_dpll - intel_fbc.c: find_compression_threshold - i915_gem_gtt.c: gtt_write_workarounds Cc: Anusha Srivatsa <anusha.srivatsa@intel.com> Cc: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Ander Conselvan de Oliveira <conselvan2@gmail.com> Acked-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1485196357-30599-2-git-send-email-rodrigo.vivi@intel.com

The drm_atomic_state struct may take a mutex when being released and so we cannot drop a reference to the drm_atomic_state from the fence release path directly, and so we need to defer that unreference to a worker.

When introduced, I thought that reducing client latency from the signaler was the priority. Since its inception the signaler has become responsible for keeping the execlists full, via the dma-fence. As this is very important to minimise overall execution time, signal the dma-fence first and then signal any waiting clients.

Only the first request added to the execlist queue can be submitted. If this request is not the first request on the queue, it means that there are already higher priority requests waiting upon the tasklet and kicking it will make no difference. This is more relevant for a later patch, where we more eagerly try and kick the tasklet to handle the submission of new requests.

We need to prevent resubmission of the context immediately following an initial resubmit (which does a lite-restore preemption). Currently we do this by disabling all submission whilst the context is still active, but we can improve this by limiting the restriction to only until we receive notification from the context-switch interrupt that the lite-restore preemption is complete.

The GPU may be in an unknown state following resume and module load. The previous occupant may have left contexts loaded, or other dangerous state, which can cause an immediate GPU hang for us. The only save course of action is to reset the GPU prior to using it - similarly to how we reset the GPU prior to unload (before a second user may be affected by our leftover state). We need to reset the GPU very early in our load/resume sequence so that any stale HW pointers are revoked prior to any resource allocations we make (that may conflict). A reset should only be a couple of milliseconds on a slow device, a cost we should easily be able to absorb into our initialisation times.

In order to reset the GPU early on in the module load sequence, we need to allocate the basic engine structs (to populate the mmio offsets etc). Currently, the engine initialisation allocates both the base struct and also allocate auxiliary objects, which depend upon state setup quite late in the load sequence. We split off the allocation callback for later and allow ourselves to allocate the engine structs themselves early. v2: Different paint for the unwind following error.

Since tweaking i915_vma_compare() we allowed constructors to skip clearing the ggtt_view believing that we didn't access the unused members. That, as it turns out, was not entirely true. In particular, i915_gem_fault() uses ret = remap_io_mapping(area, area->vm_start + (vma->ggtt_view.partial.offset << PAGE_SHIFT), (ggtt->mappable_base + vma->node.start) >> PAGE_SHIFT, min_t(u64, vma->size, area->vm_end - area->vm_start), &ggtt->mappable); i.e. the ggtt_view.partial for both normal and partial views.

This reverts commit 527b6abe (Revert "drm/i915: Use atomic commits for legacy page_flips") and reapplies commit ee042aa4. ("drm/i915: Use atomic commits for legacy page_flips") The reason for the revert was because legacy cursor updates were forced to wait for pending page flips and rendering after they were converted to atomic. Commit f79f2692 (drm/i915: Add a cursor hack to allow converting legacy page flip to atomic, v3) adds a fastpath to cursor updates, which fixes the stuttering issues. With these changes I feel confident enough to re-enable cursor updates. Legacy cursor update won't block in the following cases: - Moving cursor - Changing cursor fb The legacy cursor update will still block in the following cases: - Showing/hiding cursor. - Cursor size or scaling changes. - cursor update while cursor is invisible (could be fixed, if it turns out to be important). - Cursor tiling changes (Not sure we support tiled cursors.) - Last update was a modeset.

Parameters tile_size, tile_width and tile_height were passed in the wrong order to _intel_adjust_tile_offset() when calculating the rotated offsets. This doesn't fix any user visible bug, since for packed formats new and old offset are the same and the rotated offsets are within a tile before they are fed to _intel_adjust_tile_offset(). In that case, the offsets are unchanged. That is not true for planar formats, but those are currently not supported.
