This patch file mirrors a commit that already existed in checkouts/talos
(`a50511de7` — "grub: EFI-at-/boot fallback for BOOT-less SBC layout in
Upgrade path") but was never landed back into patches/siderolabs/talos/.
Extracted with `git format-patch` from the checkout so subsequent
`make patches` runs reproduce the same tree on a fresh clone.
Complements 0005 by handling the Upgrade code-path (in addition to the
fresh-install code-path 0005 already covers) for SBC layouts that don't
have a separate BOOT partition.
Two complementary fixes after end-to-end local installer build:
1. New talos/0001 patch — Replace hack/modules-arm64.txt with the
intersection of upstream's initramfs list and our RPi 6.12.47
build's actual modules (155 entries, down from upstream's 241).
Initramfs target was failing with exit 123 in xargs install -D
because upstream lists modules our kernel doesn't build (SATA,
HID device drivers, some upstream-only crypto helpers).
2. Makefile: add --network=host to the metal docker run.
The installer step already had it, but the metal step did not.
For local-registry builds (REGISTRY=127.0.0.1:5001), the imager
container needs --network=host to reach the host's registry to
pull the overlay image when generating the raw disk image.
Harmless on CI (no behavioural change against docker.io).
Validated locally end-to-end:
- kernel image: 234MB (RPi 6.12.47 with RP1 driver support)
- overlay image: 9.7MB (U-Boot + firmware + DTBs)
- imager image: 346MB
- installer-base: 105MB
- installer: ~100MB
- metal-arm64.raw.zst: 94MB (final flashable disk image)
The v1.13.2 rebase of pkgs 0001 only restored some RP1-related kernel
options (PINCTRL_RP1, COMMON_CLK_RP1, PINCTRL_BCM2712) because those
hunks happened to apply cleanly against upstream v1.13.0's 6.18.24-era
config-arm64. Several others were silently dropped, causing:
ld.lld: error: undefined symbol: rp1_get_platform
at the vmlinux link step (~19 min into local kernel build).
Re-added:
- CONFIG_MFD_RP1=y (defines rp1_get_platform)
- CONFIG_COMMON_CLK_RP1_SDIO=y
- CONFIG_FB_BCM2708=y (RPi framebuffer)
- CONFIG_PWM_PIO_RP1=y (RPi PWM via PIO)
- CONFIG_PWM_BRCMSTB=y (was "not set")
Local build now succeeds: svrnty/talos-rpi5-kernel:v1.13.0-local
loaded into local Docker (234MB).
- Makefile: TALOS_VERSION v1.12.4 -> v1.13.2, PKG_VERSION v1.12.0 -> v1.13.0
- siderolabs/talos 0001 (modules-arm64.txt): removed; hack/modules-arm64.txt
is a CI assertion file with no build-time references. Will be regenerated
from a real RPi 6.12.47 kernel build as a follow-up.
- siderolabs/talos 0005 (BOOT partition GRUB): rebased onto v1.13.2's
Install/Upgrade refactor. installEFI struct field is gone upstream; ported
the BOOT-partition probe + EFI-at-/boot fallback to work with the new
efiFound local var and added a bootFromEFI struct field for runGrubInstall.
- siderolabs/pkgs 0001: rebased onto v1.13.0. Kernel config header bumped
to 6.12.47. config-arm64 not fully regenerated for RPi 6.12.47 yet -- some
upstream v1.13 6.18.x symbols (LIBIE_ADMINQ, IDPF, etc) remain in the file
but the kernel's Kconfig silently drops unknown options during build.
Enable GPIO UART0 on Pi5/CM5 via dtoverlay=uart0-pi5 in
configTxtAppend. Remove the old 0002 patch that targeted the
debug UART (ttyAMA10) — Compute Blade uses GPIO 14/15 (ttyAMA0).
Renumber overlay patches (old 0003 becomes 0002).
Update README with tested serial console docs: wiring diagram,
even parity config, 3.3V requirement, and read-only limitation.

The v8 overlay patch deleted /boot/EFI/ to clean up stale firmware,
but this also removed GRUB's BOOTAA64.EFI, bricking the node.
Fix: keep SBC layout detection (write to /boot/ not /boot/EFI/) but
remove the os.RemoveAll that destroyed GRUB. Stale firmware files in
/boot/EFI/ are harmless.
Re-enable PCIe Gen 3 (dtparam=pciex1_gen=3) and full configTxt mode,
now that the overlay installer correctly writes to the EFI partition
root on SBC layouts.

Two fixes in one:
1. SBC overlay upgrade path: the overlay installer was always writing
to /boot/EFI, but on SBC layouts (no BOOT partition) the GRUB code
mounts EFI at /boot. Config.txt and firmware ended up in a stale
/boot/EFI/ subdirectory, invisible to the firmware. The installer
now detects the SBC layout and writes to the correct location.
2. PCIe Gen 3: dtparam=pciex1_gen=3 works on CM5 (the DT overrides
exist), so the custom pcie-gen3.dtbo overlay is unnecessary.
Simplified to just use dtparam in config.txt.

The CM5 DTB (bcm2712-rpi-cm5-cm5io.dtb) lacks the pciex1 alias that
the Pi 5 DTB provides, making dtparam=pciex1_gen=3 silently fail.
Add a custom device tree overlay (pcie-gen3.dtbo) that targets
/axi/pcie@1000110000 directly to set max-link-speed = <3>. The overlay
is embedded in the SBC installer and written to /boot/EFI/overlays/
during install/upgrade.

On fresh SBC images, the EFI partition has sd-boot UKI files but no
GRUB config. During upgrade, Probe() found sd-boot and used it, which
failed because RPi5/CM5 firmware lacks EFI SetVariableRT support.
Add arm64 guard to Probe(): when no GRUB config is found, skip sd-boot
probing and return a fresh GRUB config. This transitions from sd-boot
to GRUB on the first upgrade from a fresh flash.

Patch 0005 fixes talosctl upgrade on SBC layouts (RPi5/CM5) where
the disk has no separate BOOT (XFS) partition — only EFI (VFAT).
Falls back to mounting EFI at /boot for probe, install, and revert.

Talos assumes bare metal kernels support open_tree on anonymous FS
(added in 6.15). The RPi downstream kernel (6.12.x) does not, causing
shadow bind mount failures for /etc files and cascading network init
failures. This patch removes the InContainer() gate so the capability
check runs on all platforms.

ip6_gre.ko exists in Talos upstream module list (v1.12.4) but not
in the RPi downstream kernel build. Only add it to the removal side
of the patch, not our custom module list.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Talos v1.12.4 added kernel/net/ipv6/ip6_gre.ko to modules-arm64.txt.
Update our patch to match. Also silence gmake checkouts-clean stdout
in auto-update.sh to prevent it leaking into GITHUB_OUTPUT.

The overlay was using console=ttyAMA0 (GPIO 14/15) but the RPi5 debug
UART is ttyAMA10 (JST connector between HDMI ports on Pi5, test pads
TP35/TP36 on CM5). Also adds earlycon for early boot output and disables
GPIO UART on Pi5 in config.txt to avoid U-Boot compatibility issues.

Force GRUB instead of sd-boot on arm64 and pass --no-nvram to
grub-install, working around the SetVariableRT firmware limitation
that prevents in-place upgrades on RPi5/CM5 hardware.

Remove the 16K page override from the kernel patch, preserving
upstream Talos's default 4K pages. RPi5 hardware works correctly
with 4K pages — the RPi Foundation's 16K default is a TLB
performance optimization (~5%), not a hardware requirement.
Benefits:
- Correct memory accounting (4x less overhead per page)
- Full software compatibility (jemalloc, Longhorn, F2FS, etc.)
- No OOM surprises on control-plane nodes
- Aligned with upstream Talos kernel config

- Patch sbc-raspberrypi5 overlay to use Go 1.24.13 (fixes 1C/7H/12M/1L CVEs)
- Add ATTESTATION_ARGS (--provenance=true --sbom=true) to all buildx targets
- Override upstream --provenance=false via TARGET_ARGS (last flag wins)

Patch was stale — regenerated from the working checkout to match
the v1.12.3 hack/modules-arm64.txt index.

The talos patch was incorrectly replaced with pkgs-repo changes
(Pkgfile, kernel config). Restored the correct patch that modifies
hack/modules-arm64.txt in the talos checkout.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Regenerated patches to match current upstream checkouts:
- pkgs: updated kernel version, checksums, and config-arm64
- talos: reworked to patch Pkgfile, kernel config, and pkg.yaml
