From 06ec41909e31be3347f8679e9667d12ac6f7ee6e Mon Sep 17 00:00:00 2001 From: Sinclair Yeh Date: Thu, 23 Mar 2017 13:14:54 -0700 Subject: drm/vmwgfx: Add and connect CRTC helper functions Atomic mode set requires us to refactor existing vmw_stdu_crtc_set_config code into sections that check the validity of the new mode, and sections that actually program the hardware state. vmw_du_crtc_atomic_check() takes CRTC-related checking code. In a later patch, vmw_du_primary_plane_atomic_check() will take framebuffer-related checking code. These helpers won't be called until we flip on the atomic support flag or set drm_crtc_funcs->set_config to using the atomic helper. v2: * The state->num_connector is actually the total number of potential connectors, not just the one associated with the display unit. The proper one to check is ->connector_mask. * Add the check to only allow plane state to be the same as crtc state (Thanks to mlankhorst) * Make sure to turn on SVGA mode before using VRAM. SVGA mode is disabled in master_drop if dbdev is not running. v3: * Moved dot clock override to crtc_atomic_check Signed-off-by: Sinclair Yeh Signed-off-by: Thomas Hellstrom Reviewed-by: Thomas Hellstrom Acked-by: Daniel Vetter --- drivers/gpu/drm/vmwgfx/vmwgfx_kms.h | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'drivers/gpu/drm/vmwgfx/vmwgfx_kms.h') diff --git a/drivers/gpu/drm/vmwgfx/vmwgfx_kms.h b/drivers/gpu/drm/vmwgfx/vmwgfx_kms.h index cc50bf35aeca..f711b5da73e5 100644 --- a/drivers/gpu/drm/vmwgfx/vmwgfx_kms.h +++ b/drivers/gpu/drm/vmwgfx/vmwgfx_kms.h @@ -161,6 +161,7 @@ struct vmw_crtc_state { * @surf Display surface for STDU * @dmabuf display dmabuf for SOU * @content_fb_type Used by STDU. + * @dmabuf_size Size of the dmabuf, used by Screen Object Display Unit * @pinned pin count for STDU display surface */ struct vmw_plane_state { @@ -169,6 +170,7 @@ struct vmw_plane_state { struct vmw_dma_buffer *dmabuf; int content_fb_type; + unsigned long dmabuf_size; int pinned; }; @@ -342,10 +344,17 @@ int vmw_du_cursor_plane_update(struct drm_plane *plane, uint32_t src_x, uint32_t src_y, uint32_t src_w, uint32_t src_h); +/* Atomic Helpers */ void vmw_du_plane_reset(struct drm_plane *plane); struct drm_plane_state *vmw_du_plane_duplicate_state(struct drm_plane *plane); void vmw_du_plane_destroy_state(struct drm_plane *plane, struct drm_plane_state *state); +int vmw_du_crtc_atomic_check(struct drm_crtc *crtc, + struct drm_crtc_state *state); +void vmw_du_crtc_atomic_begin(struct drm_crtc *crtc, + struct drm_crtc_state *old_crtc_state); +void vmw_du_crtc_atomic_flush(struct drm_crtc *crtc, + struct drm_crtc_state *old_crtc_state); void vmw_du_crtc_reset(struct drm_crtc *crtc); struct drm_crtc_state *vmw_du_crtc_duplicate_state(struct drm_crtc *crtc); void vmw_du_crtc_destroy_state(struct drm_crtc *crtc, -- cgit v1.2.3
