            How does LinuxBoot differs from Coreboot in the firmware phase?
            Asked 2019-Oct-06 at 12:04

            I am literally confused about the use case of using LinuxBoot as the payload for Coreboot.

            I learned that LinuxBoot can completely replace the UEFI's DXE and BDS phases, and then can load the bootloader (say GRUB) or even the Linux kernel directly.

            Now, I also read that LinuxBoot can be used as the payload for Coreboot.

            If LinuxBoot can do everything from platform initialization to loading kernel, then why would someone even put Coreboot in the sequence? Simply, why the use case of using LinuxBoot as Coreboot's payload exists? What role will Coreboot play?

            ...

            ANSWER

            Answered 2018-Dec-09 at 12:45

            UEFI consists of multiple phases: SEC, PEI and DXE. LinuxBoot replaces the DXE phase, Coreboot replaces the SEC and PEI phases.

            Coreboot is responsible for the platform initialization that cannot be done by Linux, such as DRAM initialization (it is also called "training") and ACPI table generation. Linux then works as a Coreboot payload, which does things such as PCI device enumeration, and loads the bootloader or can kexec() into another Linux kernel.

            The network address can be set via the ip= parameter in the Linux kernel command line https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/filesystems/nfs/nfsroot.txt#n82.

            U-Boot uses variable bootargs to set the kernel command line.

            So you just need to use to U-Boot ip-address to update bootargs.

            Simplest way to execute binary (INTEL FSP) file from C/C++ program
            Asked 2019-Jan-19 at 09:53

            I am trying to integrate INTEL FSP in my custom OS for silicon initialization, for this I have to build OS with FSP binary at some valid address. I have searched a lot, but can not find binary integration guide anywhere, every where they are talking about APIs and FSP integration with coreboot. Is there any simplest way by which I can call binary file from my OS which is written in C?

            __udivmoddi4 is a function in libgcc which is used to implement a combined unsigned division/modulo operation for what GCC calls DI mode (doubled-up integers, 64-bit on i686). It is used for operations like this one:

            The examples are not up to date, as you have noticed by the renaming of qemu to qemu-system-x86_64.

            I managed to get the examples to work using only the cirrus video card, and by renaming the outputs of the zips (bin - bios files to bios-256k.bin). I did this because by adding the -L option I specify the bios location and qemu will look for a file called bios-256k.bin as the bios. The command to run the bios with cirrus (all done while in the foo directory) was
