Hello
Here is the output I get :
00:00.0 Class 0600: 8086:2500 (rev 03) Flags: bus master, fast devsel, latency 0 Memory at f8000000 (32-bit, prefetchable) [size=64M] Capabilities: [a0] AGP version 2.0
01:00.0 Class 0300: 10de:0028 (rev 11) Subsystem: 1048:0c20 Flags: bus master, 66Mhz, medium devsel, latency 248, IRQ 10 Memory at f4000000 (32-bit, non-prefetchable) [size=16M] Memory at f6000000 (32-bit, prefetchable) [size=32M] Expansion ROM at <unassigned> [disabled] [size=64K] Capabilities: [60] Power Management version 1 Capabilities: [44] AGP version 2.0
I was trying to tweak myself the agp code (well, mostly by copying the intel_generic_setup stuff to a intel_i820_setup stuff, but I guess there is a more clever way !). Maybe I can help with this ?
I guess that the device id's that must be added into 'agp.h' look like this :
#ifndef PCI_DEVICE_ID_INTEL_820_0 #define PCI_DEVICE_ID_INTEL_820_0 0x2500 #endif /* [...] */ #ifndef PCI_DEVICE_ID_INTEL_820_1 #define PCI_DEVICE_ID_INTEL_820_1 0x250f #endif
is it correct ?
