> [PCI]: Add MSI quirk for ServerWorks HT1000 PCIX bridge. > > This is the fix for the following problem: > > https://bugzilla.redhat.com/show_bug.cgi?id=227657 > > The bnx2 device 5706 complains about MSI not working behind a > ServerWorks HT1000 PCIX bridge. An earlier commit to fix the problem: > > e3008dedff4bdc96a5f67224cd3d8d12237082a0: > > "PCI: disable MSI by default on systems with Serverworks HT1000 chips" > > was not entirely correct, and has been reverted. > > MSI does not work on the PCIX bus because the BIOS did not set the > HT_MSI_FLAGS_ENABLE bit in the HyperTransport MSI capability on the > bridge. We use the existing quirk_msi_ht_cap() to detect the problem > and disable MSI in all buses behind it. > > Signed-off-by: Michael Chan <[EMAIL PROTECTED]> > Cc: Anantha Subramanyam <[EMAIL PROTECTED]> > Cc: Naren Sankar <[EMAIL PROTECTED]> Michael, I've queued this and my revert patch into a tree which I will push to the PCI maintainer for 2.6.24 Thanks. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
