The main differences between DSS1 and DSS2 are DSI, ++TV-out and multiple display support. ++ ++The DSS2 driver (omap-dss 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 (not tested for a while, might've gotten broken) ++- 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 ++ ++omap-dss 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, omap-dss 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 ++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 ++------------ ++ ++Currently there are no V4L2 display drivers planned, but it is possible to ++implement such either to omapfb driver, or as a separate one. From omap-dss ++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 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 a hack, but works 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. ++ ++In /sys/devices/platform/omapfb we have four files: framebuffers, ++overlays, managers and displays. You can read them so see the current ++setup, and change them by writing to it in the form of ++" : :..." ++ ++"framebuffers" lists all framebuffers. Its format is: ++ ++ p: ++ v: ++ s: ++ t: ++ ++"overlays" lists all overlays. Its format is: ++ ++ t: ++ x: ++ y: ++ iw: ++ ih: ++ w: ++ h: ++ e: ++ ++"managers" lists all overlay managers. Its format is: ++ ++ t: ++ ++"displays" lists all displays. Its format is: ++ ++ e: ++ u: ++ t: ++ h: ++ v: ++ p: ++ m: ++ ++There is also a debug sysfs file at /sys/devices/platform/omap-dss/clk which ++shows how DSS has configured the clocks. ++ ++Examples ++-------- ++ ++In the example scripts "omapfb" is a symlink to /sys/devices/platform/omapfb/. ++ ++Default setup on OMAP3 SDP ++-------------------------- ++ ++Here's the default setup on OMAP3 SDP board. All planes go to LCD. DVI ++and TV-out are not in use. The columns from left to right are: ++framebuffers, overlays, overlay managers, displays. Framebuffers are ++handled by omapfb, and the rest by the DSS. ++ ++FB0 --- GFX -\ DVI ++FB1 --- VID1 --+- LCD ---- LCD ++FB2 --- VID2 -/ TV ----- TV ++ ++Switch from LCD to DVI ++---------------------- ++ ++dviline=`cat omapfb/displays |grep dvi` ++w=`echo $dviline | cut -d " " -f 5 | cut -d ":" -f 2 | cut -d "/" -f 1` ++h=`echo $dviline | cut -d " " -f 6 | cut -d ":" -f 2 | cut -d "/" -f 1` ++ ++echo "lcd e:0" > omapfb/displays ++echo "lcd t:none" > omapfb/managers ++fbset -fb /dev/fb0 -xres $w -yres $h ++# at this point you have to switch the dvi/lcd dip-switch from the omap board ++echo "lcd t:dvi" > omapfb/managers ++echo "dvi e:1" > omapfb/displays ++ ++After this the configuration looks like: ++ ++FB0 --- GFX -\ -- DVI ++FB1 --- VID1 --+- LCD -/ LCD ++FB2 --- VID2 -/ TV ----- TV ++ ++Clone GFX overlay to LCD and TV ++------------------------------- ++ ++tvline=`cat /sys/devices/platform/omapfb/displays |grep tv` ++w=`echo $tvline | cut -d " " -f 5 | cut -d ":" -f 2 | cut -d "/" -f 1` ++h=`echo $tvline | cut -d " " -f 6 | cut -d ":" -f 2 | cut -d "/" -f 1` ++ ++echo "1 t:none" > omapfb/framebuffers ++echo "0 t:gfx,vid1" > omapfb/framebuffers ++echo "gfx e:1" > omapfb/overlays ++echo "vid1 t:tv w:$w h:$h e:1" > omapfb/overlays ++echo "tv e:1" > omapfb/displays ++ ++After this the configuration looks like (only relevant parts shown): ++ ++FB0 +-- GFX ---- LCD ---- LCD ++ \- VID1 ---- TV ---- TV ++ ++Misc notes ++---------- ++ ++OMAP FB allocates the framebuffer memory using the OMAP VRAM allocator. If ++that fails, it will fall back to dma_alloc_writecombine(). ++ ++Using DSI DPLL to generate pixel clock it is possible produce the pixel clock ++of 86.5MHz (max possible), and with that you get 1280x1024@57 output from DVI. ++ ++Arguments ++--------- ++ ++vram ++ - Amount of total VRAM to preallocate. For example, "10M". ++ ++omapfb.video_mode ++ - Default video mode for default display. For example, ++ "800x400MR-24@60". See drivers/video/modedb.c ++ ++omapfb.vram ++ - VRAM allocated for each framebuffer. Normally omapfb allocates vram ++ depending on the display size. With this you can manually allocate ++ more. For example "4M,3M" allocates 4M for fb0, 3M for fb1. ++ ++omapfb.debug ++ - Enable debug printing. You have to have OMAPFB debug support enabled ++ in kernel config. ++ ++omap-dss.def_disp ++ - Name of default display, to which all overlays will be connected. ++ Common examples are "lcd" or "tv". ++ ++omap-dss.debug ++ - Enable debug printing.

The main differences between DSS1 and DSS2 are DSI, -+TV-out and multiple display support. -+ -+The DSS2 driver (omap-dss 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 (not tested for a while, might've gotten broken) -+- 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 -+ -+omap-dss 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, omap-dss 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 -+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 -+------------ -+ -+Currently there are no V4L2 display drivers planned, but it is possible to -+implement such either to omapfb driver, or as a separate one. From omap-dss -+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 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 a hack, but works 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. -+ -+In /sys/devices/platform/omapfb we have four files: framebuffers, -+overlays, managers and displays. You can read them so see the current -+setup, and change them by writing to it in the form of -+" : :..." -+ -+"framebuffers" lists all framebuffers.
