- *
- * The PCI specs require that when a bus transaction remains unclaimed
- * for too long, the master entity on that bus is to cancel the
- * transaction it issued or passed on with a master abort. Two
- * outcomes are possible:
- *
- * - the master abort can be treated as an error that is propogated
- * back through the bus tree to the entity that ultimately originated
- * the transaction; or
- * - the transaction can be allowed to complete normally, which means
- * that writes are ignored and reads return all ones.
- *
- * In the first case, if the CPU happens to be at the tail end of the
- * tree path through one of its host bridges, it will be told there is
- * a hardware mal-function, despite being generated by software.
- *
- * For a software function (be it firmware, OS or userland application)
- * to determine how a PCI bus tree is populated, it must be able to
- * detect when master aborts occur. Obviously, PCI discovery is much
- * simpler when master aborts are allowed to complete normally.
- *
- * Unfortunately, a number of non-Intel PCI implementations have chosen
- * to treat master aborts as severe errors. The net effect is to
- * cripple PCI discovery algorithms in userland.
- *
- * On SPARCs, master aborts cause a number of different behaviours,
- * including delivering a signal to the userland application, rebooting
- * the system, "dropping down" to firmware, or, worst of all, bus
- * lockouts. 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. Bridges used in
- * SPARCs can be told to ignore all PCI errors, but not specifically
- * master aborts. Not only is this too coarse-grained, but
- * master-aborted read transactions on the primary bus end up returning
- * garbage rather than all ones.
- *
- * I have elected to work around this the only way I can think of doing
- * so right now. The following scans an additional PROM level and
- * builds a device/function map for the primary bus. I can only hope
- * this PROM information represents all devices on the primary bus,
- * rather than only a subset of them.
- *
- * Master aborts are useful in other ways too, that are not addressed
- * here. These include determining whether or not a domain provides
- * VGA, or if a PCI device actually implements PCI disablement.
