From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041228 Firefox/1.0 Fedora/1.0-8 Description of problem: I have discovered the reason why the nvidia driver doesn't autoload properly at bootup, like any other PCI device should. Kudzu's handling of modules.pcimap doesn't match the kernel's algorithm. Specifically, Kudzu doesn't handle the case where a vendor is defined but device is PCI_ANY_ID (0xffffffff). It also totally ignores the class and class_mask. I added another device entry for my specific card, and then kmodule properly reported "VIDEO nvidia". # pci module vendor device subvendor subdevice class class_mask driver_data nvidia 0x000010de 0xffffffff 0xffffffff 0xffffffff 0x00030000 0xffffffff 0x0 nvidia 0x000010de 0x00000140 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0 This problem isn't specific to the nvidia driver. Any PCI device can legitamately (by the kernel definition) use such a construct. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: Use a kernel module which defines a PCI vendor and class, but no specific device. Actual Results: kmodule did not discover the device. Expected Results: kmodule returns the proper driver module for the device. Additional info:
