Hi, Okay, with lots of help from Ani and Ben and starting with Ani's most recent radeon code which worked for LCDs and with a lot of testing on my Apple Flat Panel 17 connected to a Radeon Mac Edition card on the dvi port with a dviAtor adapter, I now have the DFP support for radeon frame buffer working well including parsing of the EDID block from OF. To control all of this, I have added two additional options to the kernel parameters passed to radeonfb.c of_edid - which means look in the OF device tree in /proc and grab the detailed timings from the EDID block dfp - overrides the monitor detection and set MT_DFP lcd - overrides the monitor detection and set MT_LCD So my kernel line in yaboot.conf looks like the following: append="video=radeon:of_edid,dfp" The panel x and y resolution are taken from the EDID block and a default_var structure is built up from the detailed timings so no change to the deault block or passing of panel_yres is needed. I have also fixed the setting of fp_XXX registers including stretch to properly intialize their values so that if OF does not set them in some correct "initial state" things will still work. (I need this to get my panel working). All of this depends on their being an EDID block in /proc under the Radeon device tree (it exists on my machine). You can simply look in /proc in the device_tree to see if one exists on your machine (need to have the monitor connected for it to be created). Since there are a lot of changes and since other people have submitted radeon patches recently, I have attached my complete files (radeonfb.c and radeon.h) in the form of a tar archive to this e-mail so that others may more easily understand the changes. I hope this helps others with flat panels but be warned I have only tested them on my own machine. So don't come back to me if your FP goes up in smoke. Use at your own RISK! BTW: Using a dviAtor, and an Apple 17 inch flat panel is a real blast and now all of my eye strain is gone! Have fun! Kevin
