| |
Your patch to add AGP support for i820 chipset doesn't work for me, if I load agpgart module with agp_try_unsupported=1 I get:
- Linux agpgart interface v0.99 (c) Jeff Hartmann agpgart: Maximum main memory to use for agp memory: 262M agpgart: Trying generic Intel routines for device id: 2501 ^^^^^^^^^^^^^ agpgart: AGP aperture is 256M @ 0xd0000000 -
That device id is different from the corresponding line in apg.h:174 #define PCI_DEVICE_ID_INTEL_820_0 0x2500
I tried to change that line in: #define PCI_DEVICE_ID_INTEL_820_0 0x2501
And it worked! But I don't know why the id for your chip is different from mine...
My motherboard is an Asus P3C2000 with a P3 500 running kernel 2.4.14
I've also another problem (I think AGP related) with DRI/DRM ang XFree 4.1.0, but I'm still working on it. If I try running some OpenGL app with more than 256Mb of RAM, the system hangs (need hard reset, no SysReq works). This happens with 2.4.13 and 2.4.14, before I hadn't tried since I had only 128Mb...) Someone can please tell me if this problem has something to do with having a "Maximum main memory to use for agp memory" value grater than AGP aperture value ?
