From 0a8d8a8667c7e66f4fa2498be18d47f8b296b430 Mon Sep 17 00:00:00 2001 From: Matt Roper <matthew.d.roper@intel.com> Date: Thu, 3 Dec 2015 11:37:38 -0800 Subject: [PATCH] drm/i915: Setup clipped src/dest coordinates during FB reconstruction (v2) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Plane state objects contain two copies of src/dest coordinates: the original (requested by userspace) coordinates in the base drm_plane_state object, and a second, clipped copy (i.e., what we actually want to program to the hardware) in intel_plane_state. We've only been setting up the former set of values during boot time FB reconstruction, but we should really be initializing both. Note that the code here probably still needs some more work since we make a lot of assumptions about how the BIOS programmed the hardware that may not always be true, especially on gen9+; e.g., * Primary plane might not be positioned at 0,0 * Primary plane could have been rotated by the BIOS * Primary plane might be scaled * The BIOS fb might be a single "extended mode" FB that spans multiple displays. * ...etc... v2: Reword/expand commit message description of assumptions we make Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by(v1): Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1449171462-30763-4-git-send-email-matthew.d.roper@intel.com Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> --- drivers/gpu/drm/i915/intel_display.c | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index eea2cd26ba17..c1a3969f3d4c 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -2598,6 +2598,8 @@ intel_find_initial_plane_obj(struct intel_crtc *intel_crtc, struct drm_plane_state *plane_state = primary->state; struct drm_crtc_state *crtc_state = intel_crtc->base.state; struct intel_plane *intel_plane = to_intel_plane(primary); + struct intel_plane_state *intel_state = + to_intel_plane_state(plane_state); struct drm_framebuffer *fb; if (!plane_config->fb) @@ -2659,6 +2661,15 @@ intel_find_initial_plane_obj(struct intel_crtc *intel_crtc, plane_state->crtc_w = fb->width; plane_state->crtc_h = fb->height; + intel_state->src.x1 = plane_state->src_x; + intel_state->src.y1 = plane_state->src_y; + intel_state->src.x2 = plane_state->src_x + plane_state->src_w; + intel_state->src.y2 = plane_state->src_y + plane_state->src_h; + intel_state->dst.x1 = plane_state->crtc_x; + intel_state->dst.y1 = plane_state->crtc_y; + intel_state->dst.x2 = plane_state->crtc_x + plane_state->crtc_w; + intel_state->dst.y2 = plane_state->crtc_y + plane_state->crtc_h; + obj = intel_fb_obj(fb); if (obj->tiling_mode != I915_TILING_NONE) dev_priv->preserve_bios_swizzle = true; -- GitLab
