jhb 2011-03-18 12:13:04 UTC FreeBSD src repository Modified files: sys/dev/pci pci.c pcivar.h Log: SVN rev 219737 on 2011-03-18 12:13:04Z by jhb Fix a few issues with HyperTransport devices and MSI interrupts: - Always enable the HyperTransport MSI mapping window for HyperTransport to PCI bridges (these show up as HyperTransport slave devices). The mapping windows in PCI-PCI bridges are enabled by existing code in the PCI-PCI bridge driver as MSI requests propagate up the device tree, but Host-PCI bridges don't really show up in that tree. - If the PCI device at domain 0 bus 0 slot 0 function 0 is not a HyperTransport device, then blacklist MSI on any other HT devices in the system. Linux has a similar quirk. PR: kern/155442 Tested by: Zack Dannar zdannar of gmail MFC after: 1 week Revision Changes Path 1.414 +43 -4 src/sys/dev/pci/pci.c 1.89 +1 -0 src/sys/dev/pci/pcivar.h
