In PCI-e SPEC r3.0, BIT 0 of Uncorrectable Error Status Register is redefined and it has an explicit requirement that when writing this field, a value of 1b is the only choice. So change previous initial maks from 0 to 1. Signed-off-by: Chen, Gong <gong.chen@xxxxxxxxxxxxxxx> --- NOTE: After scratching all use cases, this is the most obvious use case to violate the SPEC. Most of use cases just read first and then overwrite for clear purpose. Even so, such fix is obvious to not compatiable with previous SPEC definition. Do we need a dirty hack? arch/mips/pci/pci-octeon.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/mips/pci/pci-octeon.c b/arch/mips/pci/pci-octeon.c index 59cccd95688b..f1bfdc201297 100644 --- a/arch/mips/pci/pci-octeon.c +++ b/arch/mips/pci/pci-octeon.c @@ -134,7 +134,7 @@ int pcibios_plat_dev_init(struct pci_dev *dev) dconfig); /* Enable reporting of all uncorrectable errors */ /* Uncorrectable Error Mask - turned on bits disable errors */ - pci_write_config_dword(dev, pos + PCI_ERR_UNCOR_MASK, 0); + pci_write_config_dword(dev, pos + PCI_ERR_UNCOR_MASK, 1); /* * Leave severity at HW default.
