Hi,
I just found an interesting behaviour of the agpgart code in the Linux kernel with a (quite new chipset) MSI 865PE motherboard.
in the /usr/src/linux/drivers/char/agp/agpgart_be.c 2 names are in, but AFAIK Jeff Hartmann doesn't actively maintain the code anymore, (also couldn't reach him at jhartmann@precisioninsight.com), and I'm not quite sure if David Dawes got my report, so I decided to post here.
Please let me have a CC personally if you reply.
I have quite a new motherboard, (MSI 865PE) with an Sapphire Radeon 9500 128Mb card.
The agpgart module I can load fine with the 2.4.22-pre10 kernel-version:
bh:/usr/src# uname -a Linux bh 2.4.22-pre10 #1 Sat Aug 2 09:38:38 CEST 2003 i686 GNU/Linux bh:/usr/src# dmesg | grep -i agp Linux agpgart interface v0.99 (c) Jeff Hartmann agpgart: Maximum main memory to use for agp memory: 941M agpgart: Detected Intel(R) 865G chipset agpgart: AGP aperture is 64M @ 0xf8000000 bh:/usr/src#
couldn't load it with 2.4.22-pre8 (that's why the upgrade), I thought it was fixed, but now with 2.4.22-rc2 I again get the same errormsg that i got with 2.4.22-pre8:
bh:~# uname -a Linux bh 2.4.22-rc2 #1 Wed Aug 13 19:28:57 CEST 2003 i686 GNU/Linux bh:~# modprobe agpgart /lib/modules/2.4.22-rc2/kernel/drivers/char/agp/agpgart.o: init_module: No such device Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters. You may find more information in syslog or the output from dmesg /lib/modules/2.4.22-rc2/kernel/drivers/char/agp/agpgart.o: insmod /lib/modules/2.4.22-rc2/kernel/drivers/char/agp/agpgart.o failed /lib/modules/2.4.22-rc2/kernel/drivers/char/agp/agpgart.o: insmod agpgart failed bh:~# dmesg | grep -i agp Linux agpgart interface v0.99 (c) Jeff Hartmann agpgart: Maximum main memory to use for agp memory: 941M agpgart: Detected an Intel(R) 865G, but could not find the secondary device. Assuming a non-integrated video card. agpgart: unsupported bridge agpgart: no supported devices found. bh:~#
Question: Whom can I help you with more information? What info do you need more from me that can help your work?
Is the Documentation up-to-date? Chipset 865 isn't mentioned in it, (although it works with -pre10)
Intel 440LX/BX/GX/815/820/830/840/845/850/860 support CONFIG_AGP_INTEL This option gives you AGP support for the GLX component of the XFree86 4.x on Intel 440LX/BX/GX, 815, 820, 830, 840, 845, 850 and 860 chipsets.
and didnt find the ChangeLog as well...
bh:/usr/src/linux/drivers/char# find . -iname changelog -type f ./ChangeLog bh:/usr/src/linux/drivers/char# grep -i agp ChangeLog bh:/usr/src/linux/drivers/char#
TIA & HTH
