class ProxyConfig
Defined at line 274 of file ../../src/devices/bus/drivers/pci/config.h
ProxyConfig is used with PCI buses that do not support MMIO config space,
or require special controller configuration before config access. Examples
of this are IO config on x64 due to needing to synchronize CF8/CFC with
ACPI, and Designware on ARM where the controller needs to be configured to
map a given device's configuration space in before access.
For proxy configuration access all operations are passed to the pciroot
protocol implementation hosted in the same devhost as the pci bus driver.
