This commit will, 1. enable MSI mapping on a device only when MSI is enabled for that device and the MSI address matches the HT mapping window. 2. enable MSI mapping on a bridge only when a downstream device is allocated an MSI address in the mapping window PR: kern/118842 Reviewed by: jhb MFC after: 1 week |
