Kernel 2.6.23 (and possibly beyond) changed kmem_cache_create() to take 5 args instead of 6, removed the typedef for kmem_cache_t, and removed the return value for unregister_chrdev. These cahnges cause nvidia-drivers to fail to compile. This was fixed upstream for later versions of the nvidia-drivers. I don't think upstream will fix it for nvidia-drivers-1.0.7185 (which is the latest supported by my video card). Attached is a patch that will allow nvidia-drivers-1.0.7185 to build under 2.6.23. These changes are incompatible with 2.6.22 and earlier. Could an ebuild wizard change the ebuild so that if the kernel version is 2.6.23 or greater this patch gets applied? Reproducible: Always Steps to Reproduce: 1. Attempt to emerge nvidia-drivers-1.0.7185.ebuild with linux kernel 2.6.23 Actual Results: Compiler errors. Expected Results: Shiny new nvidia module.

Created attachment 136627 [details, diff] allow 1.0-7185 to compile against linux 2.6.23
71.86.01 compiles just fine, use it.
Thanks, you rock.
