The main differences between DSS1 and DSS2 are DSI, +TV-out and multiple display support, but there are lots of small improvements +also. + +The DSS2 driver (omapdss module) is in arch/arm/plat-omap/dss/, and the FB, +panel and controller drivers are in drivers/video/omap2/. DSS1 and DSS2 live +currently side by side, you can choose which one to use. + +Features +-------- + +Working and tested features include: + +- MIPI DPI (parallel) output +- MIPI DSI output in command mode +- MIPI DBI (RFBI) output +- SDI output +- TV output +- All pieces can be compiled as a module or inside kernel +- Use DISPC to update any of the outputs +- Use CPU to update RFBI or DSI output +- OMAP DISPC planes +- RGB16, RGB24 packed, RGB24 unpacked +- YUV2, UYVY +- Scaling +- Adjusting DSS FCK to find a good pixel clock +- Use DSI DPLL to create DSS FCK + +Tested boards include: +- OMAP3 SDP board +- Beagle board +- N810 + +omapdss driver +-------------- + +The DSS driver does not itself have any support for Linux framebuffer, V4L or +such like the current ones, but it has an internal kernel API that upper level +drivers can use. + +The DSS driver models OMAP's overlays, overlay managers and displays in a +flexible way to enable non-common multi-display configuration. In addition to +modelling the hardware overlays, omapdss supports virtual overlays and overlay +managers. These can be used when updating a display with CPU or system DMA. + +Panel and controller drivers +---------------------------- + +The drivers implement panel or controller specific functionality and are not +usually visible to users except through omapfb driver. They register +themselves to the DSS driver. + +omapfb driver +------------- + +The omapfb driver implements arbitrary number of standard linux framebuffers. +These framebuffers can be routed flexibly to any overlays, thus allowing very +dynamic display architecture. + +The driver exports some omapfb specific ioctls, which are compatible with the +ioctls in the old driver. + +The rest of the non standard features are exported via sysfs. Whether the final +implementation will use sysfs, or ioctls, is still open. + +V4L2 drivers +------------ + +V4L2 is being implemented in TI. + +From omapdss point of view the V4L2 drivers should be similar to framebuffer +driver. + +Architecture +-------------------- + +Some clarification what the different components do: + + - Framebuffer is a memory area inside OMAP's SRAM/SDRAM that contains the + pixel data for the image. Framebuffer has width and height and color + depth. + - Overlay defines where the pixels are read from and where they go on the + screen. The overlay may be smaller than framebuffer, thus displaying only + part of the framebuffer. The position of the overlay may be changed if + the overlay is smaller than the display. + - Overlay manager combines the overlays in to one image and feeds them to + display. + - Display is the actual physical display device. + +A framebuffer can be connected to multiple overlays to show the same pixel data +on all of the overlays. Note that in this case the overlay input sizes must be +the same, but, in case of video overlays, the output size can be different. Any +framebuffer can be connected to any overlay. + +An overlay can be connected to one overlay manager. Also DISPC overlays can be +connected only to DISPC overlay managers, and virtual overlays can be only +connected to virtual overlays. + +An overlay manager can be connected to one display. There are certain +restrictions which kinds of displays an overlay manager can be connected: + + - DISPC TV overlay manager can be only connected to TV display. + - Virtual overlay managers can only be connected to DBI or DSI displays. + - DISPC LCD overlay manager can be connected to all displays, except TV + display. + +Sysfs +----- +The sysfs interface is mainly used for testing. I don't think sysfs +interface is the best for this in the final version, but I don't quite know +what would be the best interfaces for these things. + +The sysfs interface is divided to two parts: DSS and FB. + +/sys/class/graphics/fb? directory: +mirror 0=off, 1=on +rotate Rotation 0-3 for 0, 90, 180, 270 degrees +rotate_type 0 = DMA rotation, 1 = VRFB rotation +overlays List of overlay numbers to which framebuffer pixels go +phys_addr Physical address of the framebuffer +virt_addr Virtual address of the framebuffer +size Size of the framebuffer + +/sys/devices/platform/omapdss/overlay? directory: +enabled 0=off, 1=on +input_size width,height (ie. the framebuffer size) +manager Destination overlay manager name +name +output_size width,height +position x,y +screen_width width + +/sys/devices/platform/omapdss/manager? directory: +display Destination display +name + +/sys/devices/platform/omapdss/display? directory: +ctrl_name Controller name +mirror 0=off, 1=on +update_mode 0=off, 1=auto, 2=manual +enabled 0=off, 1=on +name +rotate Rotation 0-3 for 0, 90, 180, 270 degrees +timings Display timings (pixclock,xres/hfp/hbp/hsw,yres/vfp/vbp/vsw) + When writing, two special timings are accepted for tv-out: + "pal" and "ntsc" +panel_name +tear_elim Tearing elimination 0=off, 1=on + +There are also some debugfs files at /omapdss/ which show information +about clocks and registers. + +Examples +-------- + +The following definitions have been made for the examples below: + +ovl0=/sys/devices/platform/omapdss/overlay0 +ovl1=/sys/devices/platform/omapdss/overlay1 +ovl2=/sys/devices/platform/omapdss/overlay2 + +mgr0=/sys/devices/platform/omapdss/manager0 +mgr1=/sys/devices/platform/omapdss/manager1 + +lcd=/sys/devices/platform/omapdss/display0 +dvi=/sys/devices/platform/omapdss/display1 +tv=/sys/devices/platform/omapdss/display2 + +fb0=/sys/class/graphics/fb0 +fb1=/sys/class/graphics/fb1 +fb2=/sys/class/graphics/fb2 + +Default setup on OMAP3 SDP +-------------------------- + +Here's the default setup on OMAP3 SDP board.
