Firmware Boot Chain

Overview

A boot chain is a relay of stages, each responsible for setting up just enough state to hand control to the next: ROM to firmware (SBI/UEFI), firmware to bootloader, bootloader to OS. Every handoff has a contract: where the next stage lives, what registers/tables it expects, and what memory is already set up.

Core principle: Each stage owns a contract with the next. Most boot failures are a broken contract at exactly one handoff, so isolate which handoff fails before theorizing about the stage itself.

When to Use

  • Writing or porting firmware (RISC-V SBI, UEFI services, ACPI table provision)
  • Chaining a bootloader (Limine, GRUB, U-Boot) into an OS kernel
  • A stage loads but the next never starts, or starts and immediately faults
  • Adding measured boot / TPM PCR extension to the chain
  • Discovering peripherals from a device tree or ACPI at firmware time

Map The Handoffs First

Write down the relay before debugging:

ROM -> firmware (SBI/UEFI) -> bootloader -> OS kernel
        provides: SBI calls,    loads:        expects: a0=hartid,
        memory map, ACPI/DTB     kernel+initrd  a1=DTB/ACPI ptr, MMU off

For each arrow, name: the entry address, the register/pointer contract, and the memory/translation state. The failing arrow is your bug location.

Firmware Responsibilities

  • Provide the platform description. Hand the next stage a device tree (DTB) or ACPI tables describing memory, CPUs, and peripherals. Probe peripherals from this description rather than hardcoding addresses, so one firmware serves multiple board memory maps.
  • Set the entry contract precisely. RISC-V convention passes hartid and a pointer to the platform description in fixed registers; get them exactly right. The next stage trusts them blindly.
  • Build-time configure the memory base. RAM base and the firmware's own load address differ per board (for example external DRAM at a high base on one board, on-chip SRAM on another). Make these build-time parameters, not constants buried in one file.

Bootloader Handoff Gotchas

These bite when chaining a general loader (for example Limine) into an OS:

  • Filesystem format constraints. The loader may require a specific boot filesystem (FAT16, not FAT32) and a specific layout. Get this wrong and the loader silently finds nothing.
  • Timeout and entry config. A nonzero menu timeout can stall an automated boot; a missing or misnamed entry just drops to a prompt.
  • Ramdisk/module placement. The loader places initrd/modules in memory; make sure that placement doesn't collide with where the kernel expects to run or with the stack (see bare-metal-bringup).

Measured Boot (TPM)

If the chain is measured:

  • Drive the TPM over its real interface (TIS for TPM 2.0) and gate the whole probe on the platform description actually advertising a TPM. Don't assume presence.
  • Measure before you transfer control. Each stage extends a PCR with a hash of the next stage (and relevant config) before jumping to it. Measuring after handoff measures nothing useful.
  • Use the standard protocol surface (for example EFI_TCG2_PROTOCOL) and emit a TCG2 event log so the measurements are verifiable later.
  • Test against a software TPM (swtpm) on the bench before trusting real silicon.

# Firmware Boot Chain

## Overview

A boot chain is a relay of stages, each responsible for setting up just enough state to hand control to the next: ROM to firmware (SBI/UEFI), firmware to bootloader, bootloader to OS. Every handoff has a contract: where the next stage lives, what registers/tables it expects, and what memory is already set up.

**Core principle:** Each stage owns a contract with the next. Most boot failures are a broken contract at exactly one handoff, so isolate which handoff fails before theorizing about the stage itself.

## When to Use

- Writing or porting firmware (RISC-V SBI, UEFI services, ACPI table provision)
- Chaining a bootloader (Limine, GRUB, U-Boot) into an OS kernel
- A stage loads but the next never starts, or starts and immediately faults
- Adding measured boot / TPM PCR extension to the chain
- Discovering peripherals from a device tree or ACPI at firmware time

## Map The Handoffs First

Write down the relay before debugging:

```
ROM -> firmware (SBI/UEFI) -> bootloader -> OS kernel
        provides: SBI calls,    loads:        expects: a0=hartid,
        memory map, ACPI/DTB     kernel+initrd  a1=DTB/ACPI ptr, MMU off
```

For each arrow, name: the entry address, the register/pointer contract, and the memory/translation state. The failing arrow is your bug location.

## Firmware Responsibilities

- **Provide the platform description.** Hand the next stage a device tree (DTB) or ACPI tables describing memory, CPUs, and peripherals. Probe peripherals from this description rather than hardcoding addresses, so one firmware serves multiple board memory maps.
- **Set the entry contract precisely.** RISC-V convention passes hartid and a pointer to the platform description in fixed registers; get them exactly right. The next stage trusts them blindly.
- **Build-time configure the memory base.** RAM base and the firmware's own load address differ per board (for example external DRAM at a high base on one board, on-chip SRAM on another). Make these build-time parameters, not constants buried in one file.

- **Ramdisk/module placement.** The loader places initrd/modules in memory; make sure that placement doesn't collide with where the kernel expects to run or with the stack (see `bare-metal-bringup`).

## Measured Boot (TPM)

- **Measure before you transfer control.** Each stage extends a PCR with a hash of the next stage (and relevant config) before jumping to it. Measuring after handoff measures nothing useful.
- Use the standard protocol surface (for example `EFI_TCG2_PROTOCOL`) and emit a TCG2 event log so the measurements are verifiable later.
- Test against a software TPM (swtpm) on the bench before trusting real silicon.
