[SeaBIOS] [PATCH 0/2] pci: skip pci resource allocation if instructed by platform

Posted by Abhimanyu Saini via SeaBIOS 2 months ago

A hypervisor may want to perform PCI resource allocation
(bus numbers, io and mmio ranges) and program the
resulting values into the devices itself rather than
delegate this to the firmware.

Introduce a new flag in fw_cfg, "etc/pci-noalloc", to
instruct the firmware to skip the resource allocation
phase and use whatever is already programmed in the
devices.
