Multiboot ELF Loader - Alignment

Hello, I'm continuing to play with Multiboot2 on ARM64 on a Raspberry Pi, and I've run into something which I'm trying to understand. I have an ELF file for my kernel which has two segments (I have no idea why rust is giving me two segments, but it is).  If I boot directly into the ELF file from

Submit patch/changes for Multiboot Documentation

Hello, Might be a stupid question, but how do I submit/propose changes to the multiboot specification itself? Should I just update the texinfo source from the website and attach that to my patch? Thanks, Chris ___ Grub-devel mailing list Grub-devel

Multiboot2 on aarch64: Alignment of ELF Headers

Hi, I'm continuing to work on Multiboot2 support on aarch64, and I'm looking at the alignment of the ELF headers which are passed through MB2. The alignment of the MB2 header's isn't the problem, the problem is in the ELF headers which are linked through. Some of the 8 byte wide fields (specific

oesn't seem to change any issue. Does anyone have any experience with the ARM64-EFI target or the multiboot2 code who could help me understand where the issue is? Cheers, Chris Plant ___ Grub-devel mailing list Grub-devel@gnu.org https://lists
