Kernel-level support for the Direct Rendering Infrastructure (DRI) introduced in XFree86 4.0. If you say Y here, you need to select the module that's right for your graphics card from the list below. These modules provide support for synchronization, security, and DMA transfers. Please see <http://dri.sourceforge.net/> for more details. You should also select and configure AGP (/dev/agpgart) support if it is available for your platform.
FB and CRTC helpers for KMS drivers.
GPU memory management subsystem for devices with multiple GPU memory types. Will be enabled automatically if a device driver uses it.
Choose this option if you have a 3dfx Banshee or Voodoo3 (or later), graphics card. If M is selected, the module will be called tdfx.
Choose this option if you have an ATI Rage 128 graphics card. If M is selected, the module will be called r128. AGP support for this card is strongly suggested (unless you have a PCI version).
Choose this option if you have an ATI Radeon graphics card. There are both PCI and AGP versions. You don't need to choose this to run the Radeon in plain VGA mode. If M is selected, the module will be called radeon.
Choose this option if you have an Intel I810 graphics card. If M is selected, the module will be called i810. AGP support is required for this driver to work.
Choose this option if you have a system that has "Intel Graphics Media Accelerator" or "HD Graphics" integrated graphics, including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G, G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3, Core i5, Core i7 as well as Atom CPUs with integrated graphics. If M is selected, the module will be called i915. AGP support is required for this driver to work. This driver is used by the Intel driver in X.org 6.8 and XFree86 4.4 and above. It replaces the older i830 module that supported a subset of the hardware in older X.org releases. Note that the older i810/i815 chipsets require the use of the i810 driver instead, and the Atom z5xx series has an entirely different implementation.
Choose this option if you want kernel modesetting enabled by default, and you have a new enough userspace to support this. Running old userspaces with this enabled will cause pain. Note that this causes the driver to bind to PCI devices, which precludes loading things like intelfb.
Choose this option if you have a Matrox G200, G400 or G450 graphics card. If M is selected, the module will be called mga. AGP support is required for this driver to work.
Choose this option if you have a SiS 630 or compatible video chipset. If M is selected the module will be called sis. AGP support is required for this driver to work.
Choose this option if you have a Via unichrome or compatible video chipset. If M is selected the module will be called via.
Choose this option if you have a Savage3D/4/SuperSavage/Pro/Twister chipset. If M is selected the module will be called savage.
