new approach to graphics memory management: the kernel driver never really cared about the size of stolen memory directly. that was only to figure out the maximum allocation to place the hardware cursor image somewhere at the end of the allocation done by bios. qu7uux's gm965 bios however wont steal enougth memory for his native resolution so we have todo it manually. the userspace igfx driver will figure out how much the bios allocated by looking at the gtt only. then extend the memory by creating a "fixed" physical segment. the kernel driver allocates the memory for the cursor image from normal kernel memory, and just maps it into the gtt at the end of the virtual kernel framebuffer aperture. thanks to qu7uux for the patch. |
