boards/BRINGUP.md R2/R3, FABRIC-3 SXXXIX. The entry stub cleans the cache over the image, builds an identity map (the image's GiB Normal, the rest Device) and enables MMU and caches at EL2 (or EL1); rpi5_mmu.c makes the devicetree's RAM Normal and the framebuffer uncached. Mailbox waits give up after one second; the buffer is cleaned around the exchange; the framebuffer address goes through dma-ranges, not a Pi 4 mask. New rpi5-rehearsal target runs the native image on QEMU virt at EL2. It found three more that would each have stopped the board: the PL011 shift (mine, c9519173; the host test asserted it), the GIC address not carried through /soc's ranges (new fdt_reg_address(), checked against the real Pi 5 DTB), and no timer IRQ at EL2 (HCR_EL2.IMO/FMO/AMO). Rehearsal: POST 1052 passed, same parity hash as UEFI. Standard acceptance on three ISAs: POST 1052, hash 0x82f4ae7cb2e2d424. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Build-time and integration-test utilities for the StarForth / LithosAnanke toolchain.
Contents
| File | Purpose |
|---|---|
mkcapsule.c |
Assembles .4th capsule files into capsule_generated.c baked into the kernel image. Invoked automatically by kernel/Makefile. |
mkcapsule |
Compiled host binary (rebuilt on demand). |
ttftest.c |
Host TTF glyph-rendering test — font rasterization unit tests, no QEMU needed. |
pe_reloc_gen.py |
Generates PE32+ relocation tables for the UEFI loader. |
svg_to_png.py |
Renders every tracked .svg in the repo to a same-named .png via headless Chromium; leaves the source .svg untouched, run manually. |
hermes_smoke.sh |
Hermes v1 hosted smoke test — swaps in the Hermes init capsule and prints values for manual inspection. |
hermes_channel_smoke.sh |
Exercises the full Hermes channel-negotiation lifecycle (CH-REQUEST → CH-ACCEPT → CH-CLOSE → reap) per the protocol in .claude/HERMES.md. |
hermes_tripod_smoke.sh |
Full Tripod integration test — exercises all 6 inter-VM message paths using the DEFER VM-EXEC/IS VM-EXEC dispatcher shim from init.4th. |
kconfig/ |
Vendored Linux kernel Kconfig tooling (conf/mconf/qconf), GPL-2.0. See tools/kconfig/README.md. |
mkcapsule
# Invoked automatically by the kernel build:
make -f kernel/Makefile ARCH=amd64 clean qemu
# Manual invocation (for inspection):
./tools/mkcapsule capsules/ build/amd64/kernel/capsule_generated.c
Scans capsules/ for .4th files, computes XXHash64 per capsule, assigns
type (m) to init.4th and (p) to everything else.
