Even in the first case, the SIGBUS signal that is - * eventually generated isn't delivered in a timely enough fashion to - * allow an application to reliably detect the master abort that - * ultimately caused it. - * - * This can be somewhat mitigated. On all architectures, master aborts - * that occur on secondary buses can be forced to complete normally - * because the PCI-to-PCI bridges that serve them are governed by an - * industry-wide specification. (This is just another way of saying - * that whatever justification there might be for erroring out master - * aborts is deemed by the industry as insufficient to generate more - * PCI non-compliance than there already is...) - * - * This leaves us with master aborts that occur on primary buses. - * There is no specification for host-to-PCI bridges.
