All, I am attempting to bring up a SM501 frame buffer driver on our PPC MPC8280 board. Using the Denx Kernel 2.4.25 I see that most of this is already included in the kernel.
However a few questions: The TQM5200 Board uses this driver, but I am gathering this is a PCI based video setup?; Our board uses a local bus memory interface. I.e. we have setup the SM501 to be in the SH-3/4 Slave mode. We have dedicated 32Megs of Video memory to be local only to the SM501, and mapped it to 0xF8000000 on /CS6, placing the registers at 0xFBE00000 Anyway, I have the UPMA machine setup to communicate with the SM501 and have verified basic communication with registers, etc.. When using Linux the kernel Oops's when register_framebuffer is called. I have setup the voyager.h file to use the correct addresses. Has anyone used the SM501 driver with this type of NON-Unified memory architecture? I am guessing this can be confusing to the driver since the frame buffer registers inside the SM501 need to be using offset ZERO instead of the 0xF8000000 like the MPC8280 sees. Thanks, -Russell McGuire
