Package freeze-safe Apple T1 Touch Bar driver

[monomyth]

Summary

Package the freeze-safe Apple T1 iBridge and firmware Touch Bar driver as apple-ib-drv-dkms.

• Uses the upstream t1-touchbar v0.3.0 release archive with a pinned SHA-256.
• Ships DKMS source under /usr/src/apple-ib-drv-0.3.0.
• Ships package-owned modprobe, modules-load, and udev configuration.
• Conflicts with the obsolete macbook12-spi-driver-dkms package, whose duplicate iBridge modules do not build on Linux 7.
• Builds against the newest installed kernel headers during check().

Safety

The T1 ACPI ASOC.SOCW(1) call can hard-freeze affected MacBooks. The driver defaults to skipping it on MacBookPro13,x/14,x, and this package additionally pins:

options apple_ibridge skip_acpi_power=1

The package does not perform a live USB unbind/rebind. Its udev rule keeps the iBridge in USB configuration 1, preserving both the firmware Touch Bar HID and FaceTime HD camera, and reapplies power/control=on after configuration-change and bind events.

Validation

Hardware-tested on:

• MacBookPro13,3 (2016 15-inch, T1)
• 7.2.2-arch1-1-mbp133

DKMS also built and installed successfully for 6.18.49-1-lts, but that kernel was not boot-tested.

Validated results after package-backed reboot:

• DKMS status installed for the tested 7.2.2 kernel; build/install status also passed for the unbooted LTS kernel.
• skip_acpi_power=1; kernel log confirms SOCW(1) was not executed.
• Esc, volume, brightness, playback, and Fn/F1-F12 Touch Bar controls work.
• iBridge remains at USB configuration 1 with power/control=on.
• FaceTime HD camera captured 1280x720 MJPEG and worked in Zoom.
• Internal microphone captured stereo 48 kHz audio.
• Package build and source verification pass; built package SHA-256 was 3b967fa28b57f4b9633c02f78ff5860cb09fc411a0703516efcb89ba0735f1db.

Additional custom 7.2.3 validation — 2026-09-05

Live release: 7.2.3-arch1-2-mbp133. The installed package remains apple-ib-drv-dkms 0.3.0-1 with zero altered package files; the installed udev rule matches this PR. DKMS built/installed the modules for this custom kernel, and the on-host runtime verifier confirms iBridge and Touch Bar modules loaded with matching vermagic and skip_acpi_power=1.

Additional DKMS installations exist for stock 7.2.3-arch1-2 and 6.18.49-2-lts; those are build/install-only results, not boot tests. The earlier 6.18.49-1-lts result above is historical.

There is no retained fresh 7.2.3 human test of Esc/Fn/brightness/volume/playback or new FaceTime/microphone/audio capture. Those functional results above remain labeled as 7.2.2 validation. The upgrade does not currently require a package source change; the remaining work is functional revalidation and maintainer-authorized CI. Separate Radeon/display failures do not establish that this T1 package caused them.

Follow-up on validation and CI: the completed hardware test remains MacBookPro13,3 on custom Linux 7.2.2; Linux 6.18.49 LTS was build/install-only, not boot-tested. The newer user-reported 7.2.3 boot is not yet being claimed as a Touch Bar/DKMS validation result. That needs confirmation of the installed package, module vermagic/load, skip_acpi_power and working keys/camera after the upgrade.

The current-head workflow remains action_required: https://github.com/omacom/omarchy-pkgs/actions/runs/33851956696 . Could a repository maintainer authorize it when convenient?

The separately observed Radeon graphics/wake failure should not be confused with a reproduced T1 ASOC.SOCW hard-freeze; we do not have evidence attributing that GPU failure to this driver.

Update after host reconciliation: custom 7.2.3-arch1-2-mbp133 is now verified live. Package 0.3.0-1 passes integrity checks; the installed udev rule matches the PR; both T1 modules are built, installed and loaded with correct vermagic and skip_acpi_power=1. The description now records that evidence separately. Stock 7.2.3 and LTS 6.18.49-2 remain build/install-only; fresh 7.2.3 human key/camera/audio validation is still outstanding. No package code change is indicated by these results.
