Subject: x86_64: AGP support for SiS760?

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1



The SiS760 is an AMD64 chipset and AGP support works nicely in 32bit
mode. So why is AGP_SIS only configurable if !X86_64?

Normally all AMD64 systems use only the AMD64 driver. That's because
most of the AGP setup (the aperture) is in the CPU, not on the chipset
and can be handled by a shared driver. SIS should work this way too.
