Hello all, I have a board that is using the Intel 855GME chipset. http://www.intel.com/content/www/us/en/chipsets/value-chipsets/chipset-855gme.html it has two outputs, LVDS and a VGA. My application is build on the INEGRITY OS, not LINUX. I need to rotate only the VGA output by 180 degrees. How can I do it using the 855GME? I cannot use the RandR in INTEGRITY. I am using a graphic library called PEG. http://www.swellsoftware.com/products/pegplus.php in its source I see when the data is written to a buffer that is mapped to the memory region in the kernel called __ghs_vga_videomem. The problem the same data is shown on both outputs. Here is the declaration of the memory region: MemoryReservation __ghsentry_reservedmem_vgaframebuffer = { MEMORY_RWE | MEMORY_IOCOHERENT | MEMORY_VOLATILE, 0, 0x400a0000, 0x400bffff, Other_MemoryType, true, 0xffffffff, 0xffffffff, "__ghs_vga_videomem" }; 1. Does the rotation is done by writing the data rotated or it is rotated by the hardware? 2. How do I split the two outputs? Thanks.
