Module cfg_space_emu 

Helpers that implement standardized PCI configuration space functionality.

To be clear: PCI devices are not required to use these helpers, and may choose to implement configuration space accesses manually.

Modules

header_type_consts

Constants for header type BAR counts

Structs

ConfigSpaceCommonHeaderEmulator

Common emulator for shared PCI configuration space functionality. Generic over the number of BARs (6 for Type 0, 2 for Type 1).

ConfigSpaceType0Emulator

Emulator for the standard Type 0 PCI configuration space header.

ConfigSpaceType1Emulator

Emulator for the standard Type 1 PCI configuration space header.

DeviceBars

Container type that describes a device’s available BARs

IntxInterrupt

A wrapper around a [LineInterrupt] that considers PCI configuration space interrupt control bits.

Enums

BarMemoryKind

Different kinds of memory that a BAR can be backed by

CommonHeaderResult

Result type for common header emulator operations

HeaderType

PCI configuration space header type with corresponding BAR count

Type Aliases

ConfigSpaceCommonHeaderEmulatorType0

Type alias for Type 0 common header emulator (6 BARs)

ConfigSpaceCommonHeaderEmulatorType1

Type alias for Type 1 common header emulator (2 BARs)
