Today I spend nearly 12Hours in hacking the omap3 DSS code to bring-up the TV-Out interface and finally ended-up with a kernel panic. Initially, no DSS device is got detected. After added latest patch from linus-omap tree, tv-out is detected. But the default Bits Per Pixel(BPP) is returned as 0 and Frame buffer init failed, this leads to the failure of X11. Even setting the BPP to 24 in code, is also not helping to over-come this issue. In this process, I saw a simple bug in the kernel code and submitted a patch for that.
Again planning to sit for an one more round of hacking, lets see my luck 🙂
