Currently we only set preserve_bios_swizzling when the initial fb is shared and totally miss the single-screen case. Fix this by consolidating all the logic for both cases. This seems to go back to when swizzle preservation was originally merged in commit d9ceb8163339134bd3ffb9fb87a0db4698283e32 Author: Jesse Barnes <jbarnes@xxxxxxxxxxxxxxxx> Date: Thu Oct 9 12:57:43 2014 -0700 drm/i915: preserve swizzle settings if necessary v4 Cc: Kristian Høgsberg <hoegsberg@xxxxxxxxx> Cc: Jesse Barnes <jbarnes@xxxxxxxxxxxxxxxx> Signed-off-by: Daniel Vetter <daniel.vetter@xxxxxxxxx> --- drivers/gpu/drm/i915/intel_display.c | 47 +++++++++++++++++------------------- 1 file changed, 22 insertions(+), 25 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 1142ffce66ea..9d314f889613 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -2543,14 +2543,11 @@ intel_alloc_initial_plane_obj(struct intel_crtc *crtc, mode_cmd.flags = DRM_MODE_FB_MODIFIERS; mutex_lock(&dev->struct_mutex); - if (intel_framebuffer_init(dev, to_intel_framebuffer(fb), &mode_cmd, obj)) { DRM_DEBUG_KMS("intel fb init failed\n"); goto out_unref_obj; } - - obj->frontbuffer_bits = INTEL_FRONTBUFFER_PRIMARY(crtc->pipe); mutex_unlock(&dev->struct_mutex); DRM_DEBUG_KMS("initial plane fb obj %p\n", obj); @@ -2585,19 +2582,15 @@ intel_find_initial_plane_obj(struct intel_crtc *intel_crtc, struct drm_crtc *c; struct intel_crtc *i; struct drm_i915_gem_object *obj; + struct drm_plane *primary = intel_crtc->base.primary; + struct drm_framebuffer *fb; if (!plane_config->fb) return; if (intel_alloc_initial_plane_obj(intel_crtc, plane_config)) { - struct drm_plane *primary = intel_crtc->base.primary; - - primary->fb = &plane_config->fb->base; - primary->state->crtc = &intel_crtc->base; - primary->crtc = &intel_crtc->base; - update_state_fb(primary); - - return; + fb = &plane_config->fb->base; + goto valid_fb; } kfree(plane_config->fb); @@ -2615,25 +2608,29 @@ intel_find_initial_plane_obj(struct intel_crtc *intel_crtc, if (!i->active) continue; - obj = intel_fb_obj(c->primary->fb); - if (obj == NULL) + fb = c->primary->fb; + if (!fb) continue; + obj = intel_fb_obj(fb); if (i915_gem_obj_ggtt_offset(obj) == plane_config->base) { - struct drm_plane *primary = intel_crtc->base.primary; - - if (obj->tiling_mode != I915_TILING_NONE) - dev_priv->preserve_bios_swizzle = true; - - drm_framebuffer_reference(c->primary->fb); - primary->fb = c->primary->fb; - primary->state->crtc = &intel_crtc->base; - primary->crtc = &intel_crtc->base; - update_state_fb(intel_crtc->base.primary); - obj->frontbuffer_bits |= INTEL_FRONTBUFFER_PRIMARY(intel_crtc->pipe); - break; + drm_framebuffer_reference(fb); + goto valid_fb; } } + + return; + +valid_fb: + obj = intel_fb_obj(fb); + if (obj->tiling_mode != I915_TILING_NONE) + dev_priv->preserve_bios_swizzle = true; + + primary->fb = fb; + primary->state->crtc = &intel_crtc->base; + primary->crtc = &intel_crtc->base; + update_state_fb(primary); + obj->frontbuffer_bits |= INTEL_FRONTBUFFER_PRIMARY(intel_crtc->pipe); } static void i9xx_update_primary_plane(struct drm_crtc *crtc, -- 2.1.4 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
