simics::systemc::iface::BaseAddressRegisterQueryInterface::BaseAddressRegister Struct Reference

Base Address Register (BAR) configuration. More...

#include <pci_device_query_interface.h>

Public Attributes
int	function
	PCI function that this BAR belongs to.
int	offset
	BAR offset (0x10-0x24)
bool	is_memory
	Memory or IO BAR?
bool	is_64bit
	64-bit or 32-bit (memory) BAR?
int	size_bits
	Size of BAR, in number of bits.
int	mapping_id
	Mapping ID, used to identify incoming transactions.

Detailed Description

Base Address Register (BAR) configuration.

Provided by the device, used by the Simics glue to allow snooping and simplify mapping of the device.

Note

Though not enforced by the glue, there must be as many sockets returned by getBarTargetSockets() as there are unique mapping IDs - or accesses will not be routed correctly.

The way the mapping_id is used by the Simics glue is implementation specific.
