BUG: broken I830MP AGP support in 2.4.17 and 2.4.18pre7
I'm blessed with a new Dell Inspiron 4100, which is in turn blessed with the i830MP AGP chipset. It's identical to the i830M except it doesn't have the on-chip graphics controller.
When trying to load up the agpgart module under 2.4.17, I get:
Quoted 3 lines
Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 262M
agpgart: Detected an Intel 830M, but could not find the secondary device.
Fine, I see that 2.4.18pre supposedly has fixes for the I830MP. So I compile it, slap it in place.. and get: (with 2.4.17pre7)
Quoted 4 lines
Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 262M
agpgart: unsupported bridge
agpgart: no supported devices found.
lspci yields:
Quoted 5 lines
00:00.0 Host bridge: Intel Corporation: Unknown device 3575 (rev 02)
Flags: bus master, fast devsel, latency 0
Memory atd0000000(32-bit, prefetchable) [size=256M]
Capabilities: [40] #09 [0105]
Capabilities: [a0] AGP version 2.0
So it appears not all is well with the I830MP patch. (Yes, I have tried the 'agp_unsupported' option in both cases)
