2018-10-24drm/i915/gen11: Program the scalers correctly for planar formats, v3.Maarten Lankhorst
The first 3 planes (primary, sprite 0 and 1) have a dedicated chroma upsampler to upscale YUV420 to YUV444 and the scaler should only be used for upscaling. Because of this we shouldn't program the scalers in planar mode if NV12 and the chroma upsampler are used. Instead program the scalers like on normal planes. Sprite 2 and 3 have no dedicated scaler, and need to program the selected Y plane in the scaler mode. Changes since v1: - Make the comment less confusing. Changes since v2: - Fix checkpatch warning (Matt) - gen10- -> Pre-gen11 (Ville) - PS_SCALER_MODE_PACKED -> PS_SCALER_MODE_NORMAL.

2018-10-24drm/i915/gen11: Link nv12 Y and UV planes in the atomic state, v5.Maarten Lankhorst
To make NV12 working on icl, we need to update 2 planes simultaneously. I've chosen to do this in the CRTC step after plane validation is done, so we know what planes are (in)visible. The linked Y plane will get updated in intel_plane_update_planes_on_crtc(), by the call to update_slave, which gets the master's plane_state as argument. The link requires both planes for atomic_update to work, so make sure skl_ddb_add_affected_planes() adds both states. Changes since v1: - Introduce icl_is_nv12_y_plane(), instead of hardcoding sprite numbers. - Put all the state updating login in intel_plane_atomic_check_with_state(). - Clean up changes in intel_plane_atomic_check(). Changes since v2: - Fix intel_atomic_get_old_plane_state() to actually return old state. - Move visibility changes to preparation patch. - Only try to find a Y plane on gen11, earlier platforms only require a single plane. Changes since v3: - Fix checkpatch warning about to_intel_crtc() usage. - Add affected planes from icl_add_linked_planes() before check_planes(), it's a cleaner way to do this. (Ville) Changes since v4: - Clear plane links in icl_check_nv12_planes() for clarity. - Only pass crtc_state to icl_check_nv12_planes(). - Use for_each_new_intel_plane_in_state() in icl_check_nv12_planes. - Rename aux to linked.

2018-10-17drm/i915: Use the correct crtc when sanitizing plane mappingVille Syrjälä
When we decide that a plane is attached to the wrong pipe we try to turn off said plane. However we are passing around the crtc we think that the plane is supposed to be using rather than the crtc it is currently using. That doesn't work all that well because we may have to do vblank waits etc. and the other pipe might not even be enabled here. So let's pass the plane's current crtc to intel_plane_disable_noatomic() so that it can its job correctly. To do that semi-cleanly we also have to change the plane readout to record the plane's visibility into the bitmasks of the crtc where the plane is currently enabled rather than to the crtc we want to use for the plane. One caveat here is that our active_planes bitmask will get confused if both planes are enabled on the same pipe. Fortunately we can use plane_mask to reconstruct active_planes sufficiently since plane_mask still has the same meaning (is the plane visible?) during readout. We also have to do the same during the initial plane readout as the second plane could clear the active_planes bit the first plane had already set. v2: Rely on fixup_active_planes() to populate active_planes fully (Daniel) Add Daniel's proposed comment to better document why we do this Drop the redundant intel_set_plane_visible() call Cc: stable@vger.kernel.org # fcba862e8428 drm/i915: Have plane->get_hw_state() return the current pipe Cc: stable@vger.kernel.org Cc: Dennis <dennis.nezic@utoronto.ca> Cc: Daniel Vetter <daniel@ffwll.ch> Tested-by: Dennis <dennis.nezic@utoronto.ca> Tested-by: Peter Nowee <peter.nowee@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=105637 Fixes: b1e01595a66d ("drm/i915: Redo plane sanitation during readout") Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181003145017.4527-1-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> (cherry picked from commit 62358aa4ee86481ce044bef04859820e1bc7c1d9) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

2018-10-17drm/i915: Check fb stride against plane max strideVille Syrjälä
commit 4e0b83a567e2 ("drm/i915: Extract per-platform plane->check() functions") removed the plane max stride check for sprite planes. I was going to add it back when introducing GTT remapping for the display, but after further thought it seems better to re-introduce it separately. So let's add the max stride check back. And let's do it in a nicer form than what we had before and do it for all plane types (easy now that we have the ->max_stride() plane vfunc). Only sprite planes really need this for now since primary planes are capable of scanning out the current max fb size we allow, and cursors have more stringent stride checks elsewhere.

has_drrs is a flag we can't read out. We set it when seamless DRRS is enabled in pipe_config, so intel_dump_pipe_config() and intel_pipe_config_compare() will continue to do the right thing when has_drrs is set on the real state. This removes one more dereference of crtc->config. While at it, fixup the comment and also read out M2_N2 for CHV, since we program it in the set_m_n function.

2018-10-15drm/i915: Add YCBCR 4:2:0/4:4:4 support for LSPCONShashank Sharma
LSPCON chips can generate YCBCR outputs, if asked nicely :). In order to generate YCBCR 4:2:0 outputs, a source must: - send YCBCR 4:4:4 signals to LSPCON - program color space as 4:2:0 in AVI infoframes Whereas for YCBCR 4:4:4 outputs, the source must: - send YCBCR 4:4:4 signals to LSPCON - program color space as 4:4:4 in AVI infoframes So for both 4:2:0 as well as 4:4:4 outputs, we are driving the pipe for YCBCR 4:4:4 output, but AVI infoframe's color space information indicates LSPCON FW to start scaling down from YCBCR 4:4:4 and generate YCBCR 4:2:0 output. As the scaling is done by LSPCON device, we need not to reserve a scaler for 4:2:0 outputs. V2: rebase V3: Addressed review comments from Ville - add enum crtc_output_format instead of bool ycbcr420 - use crtc_output_format=4:4:4 for modeset of LSPCON 4:2:0 output cases in this way we will have YCBCR 4:4:4 framework ready (except the ABI part) V4: Added r-b from Maarten (for v3) Addressed review comments from Ville: - Do not add a non-atomic state variable to determine lspcon output. Instead add bool in CRTC state to indicate lspcon based scaling. V5: Addressed review comments from Ville: - Change the state bool name from external scaling to something more relavent. - Keep the info and adjusted_mode structures const. - use crtc_state instead of pipe_config. - Push all the config change into lspcon_ycbcr420_config function.

2018-10-11drm/i915: DRM_FORMAT_C8 is not possible with Yf tilingPaulo Zanoni
Function intel_framebuffer_init() checks for the possibilities during framebuffer creation (addfb ioctl time). It is missing the fact that the indexed format is not supported with Yf tiling. It is worth noticing that skl_plane_format_mod_supported() correctly handles for the C8/Yf combination, but this function runs during modeset time, so we only reject the combination later. Ville recently proposed a new IGT test that only uses addfb to assert supported formats, so that IGT was failing. Add the check so we get green squares right from the start after Ville merges his test. Also drive-by fix the missing /* fall through */ in the chunk we modified by just turning it into a "break;" since IMHO breaks are easier to read than fall-throughs.

2018-10-05drm/i915: Fix ILK-IVB sprite enable delaysVille Syrjälä
Sprite enable on ILK-IVB may take two frames to complete when the hardware is in big FIFO mode (LP1+). That is not entirely great as it means the sprite enable may actually happen one frame after we've already signalled flip completion. At the very least crc checks may fail due to the sprite not yet being visible when we expect it. We already have code to deal with big FIFO mode when it comes to the sprite scaling on IVB (WaCxSRDisabledForSpriteScaling:ivb). Let's extend that workaround to kick in whenever the sprite is in the process of being enabled. Also ILK/SNB bspec has some notes to indicate that we should most likely also do the sprite scaling w/a on all three platforms, so let's do that as well. Pretty easy to reproduce on SNB/IVB. ILK has proved more elusive, but let's trust the spec and include it as well. v2: Make sure the pipe is active before the vblank wait Cc: Juha-Pekka Heikkila <juhapekka.heikkila@gmail.com> Testcase: igt/kms_plane/pixel-format-pipe-*-planes Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107749 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Juha-Pekka Heikkila <juhapekka.heikkila@gmail.com> #v1 Link: https://patchwork.freedesktop.org/patch/msgid/20181004121527.30249-1-ville.syrjala@linux.intel.com
