ntb: Use pci_enable_msix_range() instead of pci_enable_msix()

2014-04-07T17:59:20Z

As result of deprecation of MSI-X/MSI enablement functions pci_enable_msix() and pci_enable_msi_block() all drivers using these two interfaces need to be updated to use the new pci_enable_msi_range() or pci_enable_msi_exact() and pci_enable_msix_range() or pci_enable_msix_exact() interfaces.

ntb: Split ntb_setup_msix() into separate BWD/SNB routines

2014-04-07T17:59:19Z

This is an cleanup effort to make ntb_setup_msix() more readable - use ntb_setup_bwd_msix() to init MSI-Xs on BWD hardware and ntb_setup_snb_msix() - on SNB hardware. Function ntb_setup_snb_msix() also initializes MSI-Xs the way it should has been done - looping pci_enable_msix() until success or failure. Signed-off-by: Alexander Gordeev Signed-off-by: Jon Mason

NTB: Fix typo in setting one translation register

2014-04-07T17:58:14Z

In the code for Xeon devices in back-to-back mode with xeon_errata_workaround disabled, the downstream device puts the wrong value in SNB_B2B_XLAT_OFFSETL (SNB_MBAR01_DSD_ADDR vs. SNB_MBAR01_USD_ADDR). This was spotted while reading code, since the typo has no practical effect, at least for now: the low 32 bits of both constants are actually identical anyway. However, it's clearer and safer to use the right name. Signed-off-by: Roland Dreier Signed-off-by: Jon Mason

NTB: Enable Snoop on Primary Side

2013-11-20T16:57:33Z

Enable Snoop from Primary to Secondary side on BAR23 and BAR45 on all TLPs. Previously, Snoop was only enabled from Secondary to Primary side. This can have a performance improvement on some workloads. Also, make the code more obvious about how the link is being enabled. Signed-off-by: Jon Mason
