Description of problem: Although the most recent RHEL4 beta xorg-x11 RPM contains the DRI driver for the i915 chipset, the RHEL4 x86_64 kernel is missing the i915 kernel module. Manufacturers are currently introducing 64-bit capable PCs with i915 graphics hardware so the kernel should include the necessary drivers. Version-Release number of selected component (if applicable): RHEL4 x86_64 kernel (2.6.9-5.0.5.EL), as well as most recent RHEL4 beta (2.6.9-6.37.EL). How reproducible: Always Steps to Reproduce: 1. try to set up accelerated OpenGL 2. note that the i915 kernel module is missing from the RHEL4 x86_64 kernel Actual results: i915 module is not there. Expected results: i915.ko should be there Additional info: The reason why the DRM module is not built is due to the following in the kernel source: ----- drivers/char/drm/Kconfig ----- choice prompt "Intel 830M, 845G, 852GM, 855GM, 865G" depends on DRM && AGP && AGP_INTEL optional config DRM_I830 ..... config DRM_I915 ..... CONFIG_AGP_INTEL is currently not set for the x86_64 kernel. I created a separate bug for this, bug #157991. If this is resolved in a future RHEL4 release by enabling the intel-agp driver on x86_64, then this problem will be solved. Otherwise you will need to edit drivers/char/drm/Kconfig manually to remove the dependency on CONFIG_AGP_INTEL so that the i915 driver will get built. I built the i915 drm, from the standard RHEL4 kernel sources (NOT a newer i915 module from newer sources), and I can confirm that it works properly and provides accelerated OpenGL on x86_64. (pre-production Dell GX620, with onboard i945G graphics, x86_64) I did not test the i830 driver on x86_64, I do not have any such hardware.
