https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=241651 Bug ID: 241651 Summary: linuxkpi doesn't handle uninitialized PCI devices Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: jhibbits@FreeBSD.org The linuxkpi assumes that PCI devices are already fully configured. However, sometimes video cards are not configured by firmware and need to be initialized instead by FreeBSD. Linux KPI uses the PCI device resource lists directly, which can fail when a device is not initialized. According to jhb@, this should be done instead by using pci_find_bar(), and other PCI API functions, in linux_pci_get_bar() instead of trolling through the resource list directly, so that the BARs get properly initialized. -- You are receiving this mail because: You are the assignee for the bug.
