From e85d30060eddccfcfbf7fdbd61a23cfbda05cc59 Mon Sep 17 00:00:00 2001 From: Ville Syrjälä Date: Fri, 23 Mar 2018 17:35:09 +0200 Subject: drm/tinydrm: Make fb_dirty into a lower level hook MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit mipi_dbi_enable_flush() wants to call the fb->dirty() hook from the bowels of the .atomic_enable() hook. That prevents us from taking the plane mutex in fb->dirty() unless we also plumb down the acquire context. Instead it seems simpler to split the fb->dirty() into a tinydrm specific lower level hook that can be called from mipi_dbi_enable_flush() and from a generic higher level tinydrm_fb_dirty() helper. As we don't have a tinydrm specific vfuncs table we'll just stick it into tinydrm_device directly for now. v2: Deal with the fb->dirty() in tinydrm_display_pipe_update() as well (Noralf) Cc: "Noralf Trønnes" Cc: David Lechner Signed-off-by: Ville Syrjälä Reviewed-by: Noralf Trønnes Link: https://patchwork.freedesktop.org/patch/msgid/20180323153509.15287-1-ville.syrjala@linux.intel.com Reviewed-by: Noralf Trønnes Tested-by: Noralf Trønnes --- include/drm/tinydrm/tinydrm.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'include/drm/tinydrm/tinydrm.h') diff --git a/include/drm/tinydrm/tinydrm.h b/include/drm/tinydrm/tinydrm.h index 77a93ec577fd..6e2b960e25eb 100644 --- a/include/drm/tinydrm/tinydrm.h +++ b/include/drm/tinydrm/tinydrm.h @@ -26,6 +26,10 @@ struct tinydrm_device { struct drm_simple_display_pipe pipe; struct mutex dirty_lock; const struct drm_framebuffer_funcs *fb_funcs; + int (*fb_dirty)(struct drm_framebuffer *framebuffer, + struct drm_file *file_priv, unsigned flags, + unsigned color, struct drm_clip_rect *clips, + unsigned num_clips); }; static inline struct tinydrm_device * -- cgit v1.2.3
