Jonathan Currier a78bbde0f1 PCI/MSI: Add an option to write MSIX ENTRY_DATA before any reads ... [ Upstream commit cf761e3dac ] Commit 7d5ec3d361 ("PCI/MSI: Mask all unused MSI-X entries") introduced a readl() from ENTRY_VECTOR_CTRL before the writel() to ENTRY_DATA. This is correct, however some hardware, like the Sun Neptune chips, the NIU module, will cause an error and/or fatal trap if any MSIX table entry is read before the corresponding ENTRY_DATA field is written to. Add an optional early writel() in msix_prepare_msi_desc().
