PCIe Devices - PLX Technology

PCIe Compatibility with PCI Error Methods
n
PCIe requires all devices to have PCI
configuration space
l
Registers will have same definitions and field formats as in
PCI plus a new PCIe Capabilities register
– All new required PCIe error capabilities, where appropriate, will
be mapped to appropriate PCI error Status register bits
• All required PCIe error Capabilities will also be set in the PCIe
register set Status and Capabilities fields
– Optionally an PCIe device may implement the Advanced Error
Logging and Reporting register set
n
Error capabilities are very system dependent and
discussed in another chapter
