> This is the first of three patches that implement a bit field that PCI
> Express device drivers can use to indicate they need a fundamental reset
> during error recovery.
> By default, the EEH framework on powerpc does what's known as a "hot reset"
> during recovery of a PCI Express device. We've found a case where the
> device needs a "fundamental reset" to recover properly. The current PCI
> error recovery and EEH frameworks do not support this distinction.
> The attached patch (courtesy of Richard Lary) adds a bit field to pci_dev
> that indicates whether the device requires a fundamental reset during
> These patches supersede the previously submitted patch that implemented a
> fundamental reset bit field.
> Please review and let me know of any concerns.
