Hi all, I'm using DirectFB on the TI dm355 with the Montavista kernel 2.6.10. Or should I say, I'm using it successfully until I try to make it use the Davinci gfx driver for devmem.
The driver was created for the 64x, so I've had to remove any DSP calls and references to the 64x, as well as make a few tweaks to make it play nicely with the Montavista distribution of the kernel (vs TI's). Anyway, the problem at hand: The solution may be trivial, not sure. When directfb is initializing, it fails in the call to FBIOPAN_DISPLAY because within my kernel's fbmem.c "fb_pan_display" routine the test : "Yoffset + info->var.yres > info->var.yres_virtual" is true In this case, Yoffset = 12147 info->var.yres = 480 info.yres_virtual = 960 So of course it fails I'm wondering if this is just a matter of changing a setting in my directfbrc file, or the fb.modes, or...? I don't think the solution is just increasing my yres_virtual, I suspect something is wrong with the value of Yoffset. I've been trying to trace the creation of the Yoffset down into the surface pool creation where it is created (chunk), but I feel like I'm barking up the wrong tree. Thanks! Paul
