SiS755 AGP support
Hi. Has anyone got SiS 755 AGP support working? In the linux kernel
Kconfg for the AGP_AMD64 option it says
"You still need an external AGP bridge like the AMD 8151, VIA
K8T400M, SiS755. It may also support other AGP bridges when loaded
with agp_try_unsupported=1."
So it seems like SiS755 is a supported device.
In dmesg, I get
agpgart: Detected AGP bridge 0
agpgart: Maximum main memory to use for agp memory: 439M
agpgart: AGP aperture is 128M @ 0xe0000000
I have a Radeon 9200, so the open source drivers should work. But when
loading the radeon module (which happens after the agpgart, since
agpgart is compiled into the kernel (I am using the kernel-image-2.6.7-
5-amd64) it does not say anything about AGP.
[drm] Initialized radeon 1.11.0 20020828 on minor 0: ATI Technologies
Inc RV280 [Radeon 9200]
[drm] Loading R200 Microcode
glxinfo says "direct rendering: Yes", but in /var/log/XF86Config it has
a whole bunch of lines like
(II) RADEON(0): [pci] 8192 kB allocated with handle 0xffffff000030f000
(II) RADEON(0): [pci] ring handle = 0xffffff000030f000
and glxgears only has around 300 frames per second.
In a 32 bit install/kernel on this same machine, I can install the ati
binary drivers and get around 1700 fps, but they are buggy for me
(neverwinter nights leaks memory very fast).
How can I get the radeon module to see and use AGP?
