* fb: introduce flush for virtual framebufferBastian Stender2017-02-281-0/+2
| | | | | | | | | | | Some drivers need an explicit sync method to flush the virtual framebuffer to the display. It is called fb_flush(). fb_flush() gets called on fbc_putc, on fb_close and in the pattern cycle in the fbtest command.

* fb: Add shadowfb supportSascha Hauer2015-08-201-0/+3
| | | | | | | | | | | | For speeding up rendering we need shadow framebuffers. This is currently implemented in the gui functions. This does not work properly when two users (splash and fbconsole) use the same framebuffer since in this case two different shadow framebuffers will be used. This patch implements shadowfb handling in the fb core directly. With this the fb device gets a parameter 'shadowfb'. When this is true the fb core will allocate a shadow fb and provide it to the users. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * video: Add Video Pipeline (VPL) supportSascha Hauer2015-07-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Complex video pipelines are modelled with the of_graph bindings in the devicetree. This patch adds a ioctl infrastructure to issue commands to the remote endpoint of a of_graph. Currently defined ioctls are prepare/unprepare, enable/disable and get_modes. This is enough to control LVDS or HDMI encoder or simple panels. A device node which contains of_graph endpoints can be registered as a VPL entity. An entity can receive ioctls via the .ioctl callback and also issue ioctls by calling vpl_ioctl. The core itself will never iterate over the entire pipeline. Instead, the different VPL entities should forward an ioctl to the next instance in the pipeline whenever necessary. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
