This is required to enable PCI/AGP/PCI-E video cards when not using a SeaBIOS payload. When using a SeaBIOS payload it runs all option ROMs with much more complete BIOS interrupt services available than coreboot, which some option ROMs require in order to function correctly. If unsure, say N when using SeaBIOS as payload, Y otherwise. config S3_VGA_ROM_RUN bool "Re-run VGA Option ROMs on S3 resume" default y depends on VGA_ROM_RUN && HAVE_ACPI_RESUME help Execute VGA Option ROMs in coreboot when resuming from S3 suspend. When using a SeaBIOS payload it runs all option ROMs with much more complete BIOS interrupt services available than coreboot, which some option ROMs require in order to function correctly. If unsure, say N when using SeaBIOS as payload, Y otherwise. config ALWAYS_LOAD_OPROM def_bool n depends on VGA_ROM_RUN help Always load option ROMs if any are found. The decision to run the ROM is still determined at runtime, but the distinction between loading and not running comes into play for CHROMEOS. An example where this is required is that VBT (Video BIOS Tables) are needed for the kernel's display driver to know how a piece of hardware is configured to be used. config ON_DEVICE_ROM_RUN bool "Run Option ROMs on PCI devices" default n if PAYLOAD_SEABIOS default y if !PAYLOAD_SEABIOS depends on PCI && !PAYLOAD_SEABIOS || EXPERT help Execute Option ROMs stored on PCI/PCIe/AGP devices in coreboot. If disabled, only Option ROMs stored in CBFS will be executed by coreboot. If you are concerned about security, you might want to disable this option, but it might leave your system in a state of degraded functionality.

No CPU emulation is involved, so this is the fastest, but also the least secure option. (only works on x86/x64 systems) config PCI_OPTION_ROM_RUN_YABEL prompt "Secure mode" bool depends on !GEODE_VSA help If you select this option, the x86emu CPU emulator will be used to execute PCI Option ROMs. This option prevents Option ROMs from doing dirty tricks with the system (such as installing SMM modules or hypervisors), but it is also significantly slower than the native Option ROM initialization method. This is the default choice for non-x86 systems. endchoice config YABEL_PCI_ACCESS_OTHER_DEVICES prompt "Allow Option ROMs to access other devices" bool depends on PCI_OPTION_ROM_RUN_YABEL help Per default, YABEL only allows Option ROMs to access the PCI device that they are associated with. However, this causes trouble for some onboard graphics chips whose Option ROM needs to reconfigure the north bridge. config YABEL_PCI_FAKE_WRITING_OTHER_DEVICES_CONFIG prompt "Fake success on writing other device's config space" bool depends on YABEL_PCI_ACCESS_OTHER_DEVICES help By default, YABEL aborts when the Option ROM tries to write to other devices' config spaces. With this option enabled, the write doesn't follow through, but the Option ROM is allowed to go on. This can create issues such as hanging Option ROMs (if it depends on that other register changing to the written value), so test for impact before using this option. config YABEL_VIRTMEM_LOCATION prompt "Location of YABEL's virtual memory" hex depends on PCI_OPTION_ROM_RUN_YABEL && EXPERT default 0x1000000 help YABEL requires 1MB memory for its CPU emulation. This memory is normally located at 16MB. config YABEL_VIRTMEM_LOCATION hex depends on PCI_OPTION_ROM_RUN_YABEL && !EXPERT default 0x1000000 config YABEL_DIRECTHW prompt "Direct hardware access" bool depends on PCI_OPTION_ROM_RUN_YABEL && ARCH_X86 help YABEL consists of two parts: It uses x86emu for the CPU emulation and additionally provides a PC system emulation that filters bad device and memory access (such as PCI config space access to other devices than the initialized one). When choosing this option, x86emu will pass through all hardware accesses to memory and I/O devices to the underlying memory and I/O addresses. While this option prevents Option ROMs from doing dirty tricks with the CPU (such as installing SMM modules or hypervisors), they can still access all devices in the system.
