Debugger System Call Interfaces
High Availability System Call Interfaces
The following table lists debugger system call interfaces that have been
added to support High Availability (HA) functionality. Note that these
depend on the Hot Swap Controller being present in the system
configuration. For further details refer to the CPX750 High Availability
PPCBug Firmware User’s Manual, listed in
.
PCIDOM allows a CPU module to claim control of one or both of the PCI
domains. In an active/standby arrangement, for example, the CPU in
domain A uses PCIDOM to take control of both the local PCI domain,
domain A, and of the remote domain, domain B.
PWROFF and PWRON allow the user to power off or to power on a
module in order to hot swap it.
