--nFreZHaLTZJo0R7j Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable My PC has built-in intel G33 graphics, which I'm trying to get to work in something better then vesa. Following the instructions in http://lists.freebsd.org/pipermail/freebsd-stable/2008-January/039638.html I have compiled and installed the driver and kernel modules from the git trees for drm and the xf86-video-intel driver from today. I also patched agp_i810.c to remove the comments from the chipset identifiers and rebuilt the kernel. After loading the i915.ko kernel module, and starting X with a config file using the intel driver, I still get; (II) intel(0): xf86BindGARTMemory: bind key 1 at 0x006ff000 (pgoffset 1791) (WW) intel(0): xf86BindGARTMemory: binding of gart memory with key 1 at offset 0x6ff000 failed (Invalid argument) Fatal server error: Couldn't bind memory for front buffer In dmesg output I see: agp0: trying to bind into stolen memory Looking at the Xorg.0.log, the xf86-video-intel driver and the drm and dri drivers seem to initialize OK. Grepping through the source, this error seems to originate in /usr/src/sys/pci/agp_i810.c;=20 if ( sc->chiptype !=3D CHIP_I810 ) { if ( (offset >> AGP_PAGE_SHIFT) < sc->stolen ) { device_printf(dev, "trying to bind into stolen memo= ry"); return EINVAL; } [disclaimer: I'm not a software engineer by education or trade, just a mechanical engineer who likes to tinker with computers and software] I've been reading the agp code, the intel driver code and I've skimmed the intel docs. I find the code quite hard to understand, and the intel docs nigh-on unreadable.=20 Would modifying the if-statement to not produce this error on the CHIP_G33 fix this problem? Or would it horribly blow up in my face? Any help to get this to work would be very much appreciated!
