Firmware, boot & trust

What runs before the kernel, and how you prove what ran.

Organisation Repos Site Docs What it holds
go-tpm2 8 site docs TPM 2.0 end to end: transports, the command layer, EFI_TCG2, measured boot, event-log replay and remote attestation.
go-coff 4 site docs PE/COFF for UEFI — an object-to-EFI linker, a signing and conversion CLI, and a self-extracting EFI packer.
go-bootloaders 2 site docs GRUB and systemd-boot tooling, composed on the storage, UEFI and TPM stacks rather than reimplementing them.
cloud-boot 7 site docs Booting the machine: a TamaGo UEFI payload, a unified kernel image, an init, kernels, ISOs, SEV-SNP.
nano-container-linux 7 site docs A minimal container host — OCI initrd and PXE boot, a DNS daemon, an OpenPubKey agent.

Counts are public repositories that hold code; brand, docs and landing repositories are excluded.
