Detailed Description

Interface that allows the Simics glue to perform snooping and automatic connection of the device's target sockets based on the number of BARs implemented.

Member Typedef Documentation

◆ BarInfo

typedef std::vector<BaseAddressRegister> simics::systemc::iface::BaseAddressRegisterQueryInterface::BarInfo

BAR register information.

Returns: a vector that contains up to six entries per PCI(e) function, one for each BAR. A 64-bit BAR has is_64bit=true and is represented as a single entry, not two. Unimplemented bars must be left out of the list.

Note: The BAR entries must be ordered by their function number.

◆ BarSockets

typedef std::vector<std::pair<BaseAddressRegister, sc_core::sc_object *> > simics::systemc::iface::BaseAddressRegisterQueryInterface::BarSockets

IO/Memory space target socket(s).

One socket per (implemented) BAR and type (up to six sockets), per function.

Note: Currently only the mapping_id of the BAR data is used by the Simics glue.; If multiple BARs are to be routed to the same target socket using the same mapping_id, only list the socket once using any of the corresponding BARs.
