Expected Results: As far as I understand, this comes from inconsistencies between include files in XFree86 and the redhat kernel, both being plain redhat rpms. Additional info: From the web pages http://www.cse.unsw.edu.au/~chak/linux/c400.html http://www.jongans.com/gateway1450.html we know that the 830M video driver can be patch to run: 1) patch /usr/src/linux-2.4.18-5/drivers/char/agp/agpgart_be.c to create the new module agpgart.o This works fine. 2) patch XFree86-4.2.0/xc/programs/Xserver/hw/xfree86/os-support/bsd/drm/kernel/i830/i830_dma.c But here, even if the patch can work with some minor changes, the compilation fails. This is not surprising as it already fails without any patch. I was answered that with the plain kernel-2.4.18 (not readhat one) this would work. So I would be glad to see patches for this part of the kernel (or XFree86?) so that we could take advantage of XFree86 patches. Today, the 830M is working without i830.o, i.e. without DRI, as long as agpgart.o is patched. I would be glad to be able to use also DRI while keeping redhat kernel. N.B. The laptop that I used for this is an HP omnibook xt6050. This bug is related to Bug - 65661 and Bug - 66687 but with a more general framework.
This is not a bug. The Red Hat kernel contains a bug fixed version of the XFree86 4.2.0 DRM code. We do not support user compiled kernels, or kernel modules wether or not it comes from sources we ship or not. We only support binaries that we ship. Please note that bugzilla is not a user technical support forum, it is only for reporting and tracking bugs.
