An MMIO read from a PCI device that doesn't exist or doesn't respond
causes a PCI error. There's no real data to return to satisfy the
CPU read, so most hardware fabricates ~0 data.
This patch series adds PCI_ERROR_RESPONSE definition and other helper
definition SET_PCI_ERROR_RESPONSE and RESPON
An MMIO read from a PCI device that doesn't exist or doesn't respond
causes a PCI error. There's no real data to return to satisfy the
CPU read, so most hardware fabricates ~0 data.
This patch series adds PCI_ERROR_RESPONSE definition and other helper
definition SET_PCI_ERROR_RESPONSE and RESPON
