From: Sui Jingfeng <suijingfeng at loongson.cn> This patch adds the aperture_contain_firmware_fb() function to do the determination. Unfortunately due to the fact that apertures list will be freed dynamically, the location and size information of the firmware fb will be lost after dedicated drivers call aperture_remove_conflicting_devices(), aperture_remove_conflicting_pci_...

fb_do_apertures_overlap is returning wrong value when one aperture is completely whithin the other. Add generic ranges_overlap macro (probably kernel.h candidate) and use it here.

This patch enlarges the PCI GART aperture to 512 MB. The current 64MB aperture is too small and should be enlarged. The optimal amound may be card/system-dependent, so a more sophisticated approach may be preferable. In particular, if RAMIN is less than 1MB, a 512MB aperture won't fit.

From: Thierry Reding <treding at nvidia.com> Hi Ben, these are a couple of patches that are in preparation for adding GV11B support. The fundamental issue that these are trying to solve is that the GV11B is the first Tegra incarnation of the GPU where the aperture really matters. All prior generations would accept any of them. For dGPUs we usually allocate memory in VRAM, so the default aperture (0) is correct. However, on Tegra the buffers are allocated in system memory, and since the GPU actually cares about the aperture, we need to ensure that the apertu...

...his function is a no-op on non-x86 architectures. 2) It does not take the PCI Bar may get relocated into consideration. 3) It is not effective for the PCI device without a dedicated VRAM Bar. 4) It is device-agnostic, thus it has to waste the effort to iterate all of the PCI Bar to find the VRAM aperture. 5) It has invented lots of methods to determine which one is the default boot device on a multiple video card coexistence system. But this is still a policy because it doesn't give the user a choice to override. With the observation that device drivers or video aperture helpers may have...

...Component: Driver/nouveau Product: xorg Hi, I will report that when I use BFG Technologies GeForce 7300 GT AGP graphics card (NVIDIA GeForce 7300 GT AGP 512 MB DDR2 SDRAM) on FIC VA-503+ mainboard (VIA Technologies Apollo MVP3 chipset), it will not display text characters when AGP aperture setting is set to 64 MB, 128 MB, or 256 MB settings. If the AGP aperture size is set to 32 MB or less (i.e., 4 MB, 8 MB, 16 MB, and 32 MB), the text characters will get displayed correctly on the screen. The same exact bug has also been observed with EVGA GeForce 6200 AGP graphics card (NVIDIA GeFo...
