25 Kernel-level support for the Direct Rendering Infrastructure (DRI)
26 introduced in XFree86 4.0. If you say Y here, you need to select
27 the module that's right for your graphics card from the list below.
28 These modules provide support for synchronization, security, and
29 DMA transfers. Please see <http://dri.sourceforge.net/> for more
30 details. You should also select and configure AGP
31 (/dev/agpgart) support if it is available for your platform.

166 with ARM Mali GPUs using an userspace Blob.
167 This option is not supported by upstream developers and should be
168 removed as soon as possible and be considered as a broken and
