* drm/i915: skylake primary plane scaling using shared scalersChandra Konduru2015-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables skylake primary plane scaling using shared scalers atomic desgin. v2: -use single copy of scaler limits (Matt) v3: -move detach_scalers to crtc commit path (Matt) -use values in plane_state->src as regular integers (me) v4: -changes to align with updated scaler structures (Matt, me) -keep plane src rect in 16.16 format (Matt, Daniel) v5: -Rebased on top of 90/270 rotation changes (me) -Fixed an issue introduced by 90/270 changes where plane programming is using drm_plane->state rect instead of intel_plane->state rect. This change also required for scaling to work properly. (me) -With 90/270, updated limits to cover both portrait and landscape usages (me) -Refactored skylake_update_primary_plane to reduce its size (Daniel) Added helper functions for refactoring are comprehended enough to be used for skylake_update_plane (for sprite) too. One stop towards having single function for all planes. v6: -Added fixme note when checking plane_state->src width in update_plane (Daniel) -Release lock when failing to colorkey request with active scaler (Daniel) Signed-off-by: Chandra Konduru <chandra.konduru@intel.com> Reviewed-by: matthew.d.roper@intel.com Reviewed-by: sonika.jindal@intel.com (v5) Testcase: igt/kms_plane_scaling Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
* drm/i915: copy staged scaler state from drm state to crtc->config.Chandra Konduru2015-04-13
| | | | | | | | | | | | This is required for commit to perform as per staged assignment of scalers until atomic crtc commit function is available. As a place holder doing this copy from intel_atomic_commit for scaling to operate correctly.

* drm/i915: Ensure setting up scalers into staged crtc_stateChandra Konduru2015-04-13
| | | | | | | | | | | | | | | | From intel_atomic_check, call intel_atomic_setup_scalers() to assign scalers based on staged scaling requests. Fail the transaction if setup returns error. Setting up of scalers should be moved to atomic crtc check once atomic crtc is ready. v2: -updated parameter passing to setup_scalers (me) Signed-off-by: Chandra Konduru <chandra.konduru@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
* drm/i915: setup scalers for crtc_compute_configChandra Konduru2015-04-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added intel_atomic_setup_scalers to setup scalers based on staged scaling requests from a crtc and its planes. If staged requests are supportable, this function assigns scalers to requested planes and crtc. Note that the scaler assignement itself is staged into crtc_state and respective plane_states for later commit after all checks have been done. overall high level flow: - scaler requests are staged into crtc_state by planes/crtc - check whether staged scaling requests can be supported - add planes using scalers that aren't in current transaction - assign scalers to requested users - as part of plane commit, scalers will be committed (i.e., either attached or detached) to respective planes in hw - as part of crtc_commit, scaler will be either attached or detached to crtc in hw crtc_compute_config calls intel_atomic_setup_scalers() to start scaler assignments as per scaler state in crtc config. This call should be moved to atomic crtc once it is available. v2: -removed a log message (me) -changed input parameter to crtc_state (me) v3: -remove assigning plane_state returned by drm_atomic_get_plane_state (Matt) -fail if there is an error from drm_atomic_get_plane_state (Matt) v4: -changes to align with updated scaler structure (Matt, me) v5: -added addtional checks before enabling HQ mode (me) -added comments to enable HQ mode (Matt) Signed-off-by: Chandra Konduru <chandra.konduru@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
* drm/i915: Clear crtc atomic flags at beginning of transactionMatt Roper2015-04-10
| | | | | | | | | | | | | | | | | Once we have full atomic modeset, these kind of flags should be in a real intel_crtc_state that's tracked properly. In the meantime, make sure we clear out any old flags at the beginning of a transaction so that we don't wind up seeing leftover flags from old transactions that were checked, but never went to the commit step. At the moment, a failed check or prepare could leave stale flags behind that interfere with the next atomic transaction. v2: Just do a memset; the series this patch was originally part of placed additional fields into the structure that shouldn't be cleared, but that's no longer the case.

* drm/atomic-helper: Rename commmit_post/pre_planesDaniel Vetter2015-02-23
| | | | | | | | | | | | | | | | | | These names only make sense because of backwards compatability with the order used by the crtc helper library. There's not really any real requirement in the ordering here. So rename them to something more descriptive and update the kerneldoc a bit. Motivated in a discussion with Laurent about how to restore plane state for dpms for drivers with runtime pm. v2: Squash in fixup from Stephen Rothwell to fix a conflict with tegra.

* drm/i915: Add atomic_get_property entrypoint for connectors (v2)Matt Roper2015-01-27
| | | | | | | | | | | | | | | | | | | | | Even though we only support atomic plane updates at the moment, we still need to add an .atomic_get_property() entrypoint for connectors before we allow the driver to flip on the DRIVER_ATOMIC bit. As soon as that bit gets set, the DRM core will start adding atomic connector properties (in addition to the plane properties we care about at the moment), so we need to be able to handle the new way the DRM core will interact with us. For simplicity, we just lookup driver-specific connector properties in the usual shadow array maintained by the core. Once we get real atomic modeset support for crtc's and planes, this code should be re-written to pull the data out of crtc/connector state structures. v2: Fix intel_dvo and intel_dsi that I missed on the first pass (Ander) Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Ander Conselvan de Oliveira <conselvan2@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
* drm/i915: Add main atomic entrypoints (v2)Matt Roper2015-01-27
Add the top-level atomic entrypoints for check/commit. These won't get called yet; we still need to either enable the atomic ioctl or switch to using the non-transitional atomic helpers for legacy operations. v2: - Use plane->pipe rather than plane->possible_crtcs while ensuring that only a single CRTC is in use. Either way will work fine since i915 drm_plane's are always tied to a single CRTC, but plane->pipe is slightly more intuitive. (Ander) - Simplify crtc/connector checking logic.
