} /** * amdgpu_dm_atomic_check() - Atomic check implementation for AMDgpu DM. * @dev: The DRM device * @state: The atomic state to commit * * Validate that the given atomic state is programmable by DC into hardware. * This involves constructing a &struct dc_state reflecting the new hardware * state we wish to commit, then querying DC to see if it is programmable. It's * important not to modify the existing DC state. Otherwise, atomic_check * may unexpectedly commit hardware changes. * * When validating the DC state, it's important that the right locks are * acquired. For full updates case which removes/adds/updates streams on one * CRTC while flipping on another CRTC, acquiring global lock will guarantee * that any such full update commit will wait for completion of any outstanding * flip using DRMs synchronization events. See * dm_determine_update_type_for_commit() * * Note that DM adds the affected connectors for all CRTCs in state, when that * might not seem necessary. This is because DC stream creation requires the * DC sink, which is tied to the DRM connector state. Cleaning this up should * be possible but non-trivial - a possible TODO item. * * Return: -Error code if validation failed. */ static int amdgpu_dm_atomic_check(struct drm_device *dev, struct drm_atomic_state *state) { struct amdgpu_device *adev = dev->dev_private; struct dm_atomic_state *dm_state = NULL; struct dc *dc = adev->dm.dc; struct drm_connector *connector; struct drm_connector_state *old_con_state, *new_con_state; struct drm_crtc *crtc; struct drm_crtc_state *old_crtc_state, *new_crtc_state; struct drm_plane *plane; struct drm_plane_state *old_plane_state, *new_plane_state; enum surface_update_type update_type = UPDATE_TYPE_FAST; enum surface_update_type overall_update_type = UPDATE_TYPE_FAST; int ret, i; /* * This bool will be set for true for any modeset/reset * or plane update which implies non fast surface update. */ bool lock_and_validation_needed = false; ret = drm_atomic_helper_check_modeset(dev, state); if (ret) goto fail; if (adev->asic_type >= CHIP_NAVI10) { for_each_oldnew_crtc_in_state(state, crtc, old_crtc_state, new_crtc_state, i) { if (drm_atomic_crtc_needs_modeset(new_crtc_state)) { ret = add_affected_mst_dsc_crtcs(state, crtc); if (ret) goto fail; } } } for_each_oldnew_crtc_in_state(state, crtc, old_crtc_state, new_crtc_state, i) { if (!drm_atomic_crtc_needs_modeset(new_crtc_state) && !new_crtc_state->color_mgmt_changed && old_crtc_state->vrr_enabled == new_crtc_state->vrr_enabled) continue; if (!new_crtc_state->enable) continue; ret = drm_atomic_add_affected_connectors(state, crtc); if (ret) return ret; ret = drm_atomic_add_affected_planes(state, crtc); if (ret) goto fail; } /* * Add all primary and overlay planes on the CRTC to the state * whenever a plane is enabled to maintain correct z-ordering * and to enable fast surface updates. */ drm_for_each_crtc(crtc, dev) { bool modified = false; for_each_oldnew_plane_in_state(state, plane, old_plane_state, new_plane_state, i) { if (plane->type == DRM_PLANE_TYPE_CURSOR) continue; if (new_plane_state->crtc == crtc || old_plane_state->crtc == crtc) { modified = true; break; } } if (!modified) continue; drm_for_each_plane_mask(plane, state->dev, crtc->state->plane_mask) { if (plane->type == DRM_PLANE_TYPE_CURSOR) continue; new_plane_state = drm_atomic_get_plane_state(state, plane); if (IS_ERR(new_plane_state)) { ret = PTR_ERR(new_plane_state); goto fail; } } } /* Remove exiting planes if they are modified */ for_each_oldnew_plane_in_state_reverse(state, plane, old_plane_state, new_plane_state, i) { ret = dm_update_plane_state(dc, state, plane, old_plane_state, new_plane_state, false, &lock_and_validation_needed); if (ret) goto fail; } /* Disable all crtcs which require disable */ for_each_oldnew_crtc_in_state(state, crtc, old_crtc_state, new_crtc_state, i) { ret = dm_update_crtc_state(&adev->dm, state, crtc, old_crtc_state, new_crtc_state, false, &lock_and_validation_needed); if (ret) goto fail; } /* Enable all crtcs which require enable */ for_each_oldnew_crtc_in_state(state, crtc, old_crtc_state, new_crtc_state, i) { ret = dm_update_crtc_state(&adev->dm, state, crtc, old_crtc_state, new_crtc_state, true, &lock_and_validation_needed); if (ret) goto fail; } /* Add new/modified planes */ for_each_oldnew_plane_in_state_reverse(state, plane, old_plane_state, new_plane_state, i) { ret = dm_update_plane_state(dc, state, plane, old_plane_state, new_plane_state, true, &lock_and_validation_needed); if (ret) goto fail; } /* Run this here since we want to validate the streams we created */ ret = drm_atomic_helper_check_planes(dev, state); if (ret) goto fail; if (state->legacy_cursor_update) { /* * This is a fast cursor update coming from the plane update * helper, check if it can be done asynchronously for better * performance. */ state->async_update = !drm_atomic_helper_async_check(dev, state); /* * Skip the remaining global validation if this is an async * update.
