This code acts 12 as a sort of "AGP driver" for the motherboard's chipset. 13 14 If you need more texture memory than you can get with the AGP GART 15 (theoretically up to 256 MB, but in practice usually 64 or 128 MB 16 due to kernel allocation issues), you could use PCI accesses 17 and have up to a couple gigs of texture space. 18 19 Note that this is the only means to have X/GLX use 20 write-combining with MTRR support on the AGP bus. Without it, OpenGL 21 direct rendering will be a lot slower but still faster than PIO. 22 23 To compile this driver as a module, choose M here: the 24 module will be called agpgart. 25 26 You should say Y here if you want to use GLX or DRI. 27 28 If unsure, say N. 29 30config AGP_ALI 31 tristate "ALI chipset support" 32 depends on AGP && X86_32 33 help 34 This option gives you AGP support for the GLX component of 35 X on the following ALi chipsets. The supported chipsets 36 include M1541, M1621, M1631, M1632, M1641,M1647,and M1651. 37 For the ALi-chipset question, ALi suggests you refer to 38 <http://www.ali.com.tw/>. 39 40 The M1541 chipset can do AGP 1x and 2x, but note that there is an 41 acknowledged incompatibility with Matrox G200 cards. Due to 42 timing issues, this chipset cannot do AGP 2x with the G200. 43 This is a hardware limitation. AGP 1x seems to be fine, though. 44 45config AGP_ATI 46 tristate "ATI chipset support" 47 depends on AGP && X86_32 48 help 49 This option gives you AGP support for the GLX component of 50 X on the ATI RadeonIGP family of chipsets. 51 52config AGP_AMD 53 tristate "AMD Irongate, 761, and 762 chipset support" 54 depends on AGP && X86_32 55 help 56 This option gives you AGP support for the GLX component of 57 X on AMD Irongate, 761, and 762 chipsets. 58 59config AGP_AMD64 60 tristate "AMD Opteron/Athlon64 on-CPU GART support" 61 depends on AGP && X86 && AMD_NB 62 help 63 This option gives you AGP support for the GLX component of 64 X using the on-CPU northbridge of the AMD Athlon64/Opteron CPUs. 65 You still need an external AGP bridge like the AMD 8151, VIA 66 K8T400M, SiS755.
