2 board configurations · one shared discussion · Aurora Linux assessment

Broad kernel integration is present: Aurora's working tree includes this product's core platform, NVMe, GPU, DCP display, USB, wireless and audio paths. Board-specific exceptions and Aurora's newer development work are listed below; this assessment is not a blanket pass for every port, firmware version or installation.

Refreshed October 8, 2026. Baseline: aurora-wip at 35c7d87921c0. Open PR and feat/sep results are identified separately. These statuses use Aurora's public source and contributor reports with their actual tested kernels identified. The baseline source and every linked PR state were rechecked; no new physical test was performed for this update.

Board	Silicon / SoC	Model / configuration	Year	Aurora assessment
J456	M1 · T8103	iMac 24-inch, 4× USB-C	2021	🔵 Broad kernel integration

Evidence key · Aurora source and Aurora hardware reports

Marker	Meaning
🔵 Integrated source	The relevant implementation or enabled board description exists in the pinned Aurora working tree. This is source evidence, not a new hardware test.
🟢 Hardware report	A linked public Aurora report names the board and tested feature. Read its revision and limits.
🟠 Development / partial	An open PR, feature branch, incomplete configuration or qualification remains.
🔴 Source gap	The required driver match or board path is absent or disabled in this snapshot.
⚪ Unverified	The evidence checked here does not establish this capability.
—	Not fitted to this product.

A report from another board is not a pass for this board. An open PR may work on hardware without being integrated into aurora-wip. A driver being enabled does not by itself establish firmware availability, userspace integration or a complete usable installation.

🧩 Core platform

Feature	Aurora status	Evidence / boundary
Board description / kernel build target	🔵 Integrated source	Every board above has a DTS and a Makefile target. Bootloader handoff and a repeatable installer run are separate checks.
NVMe / ANS storage	🔵 Integrated source	Enabled storage nodes in every board tree; CONFIG_NVME_APPLE=m.
CPU frequency / idle	🔵 Integrated source	Enabled cluster-frequency nodes; Apple cpufreq, CPU idle and PMU options configured. CPU idle is not whole-system suspend qualification.
Interrupts / IOMMU / platform buses	🔵 Integrated source	Apple AIC, DART, GPIO, I²C, SPI, SPMI and RTKit platform options are configured; board-specific nodes are in the linked DTS sources.
SMC / RTC / sensors	🔵 Integrated source	SMC paths present; MACSMC RTC, input, hwmon and power drivers configured.

🎨 Graphics, audio and media

Feature	Aurora status	Evidence / boundary
GPU acceleration	🔵 Kernel driver integrated	Enabled AGX node and matching driver entry for the listed SoCs; CONFIG_DRM_ASAHI=m. Mesa, firmware and application / conformance results must be recorded separately.
Display pipeline	🔵 DCP integrated	Enabled DCP / DCPEXT paths and CONFIG_DRM_APPLE=m. Connector routing, refresh modes, brightness and hotplug remain board- and firmware-specific.
Speakers / headphone jack	🟠 Headphone link; speaker route missing	MCA / Mac audio drivers and codecs are configured. Audio routing in source does not establish safe speaker tuning or a playback qualification.
Built-in microphones	🔵 AOP audio enabled	Board AOP audio state checked; CONFIG_SND_SOC_APPLE_AOP_AUDIO=m. Record actual capture quality and channel behaviour per board.
Built-in camera	🔵 ISP integrated	Enabled ISP node with a matching driver family and CONFIG_VIDEO_APPLE_ISP=m. Camera sensor / firmware and runtime capture still need board evidence.
Hardware video decode	🔵 AVD source; 🟠 qualification	AVD nodes and decoder driver are present and CONFIG_VIDEO_APPLE_AVD=m. Decoder fixes in #45 are merged into aurora-wip; codec / stream coverage and application integration are not a general pass.
Video encode / ProRes	⚪ Unverified	This audit does not establish an integrated, hardware-qualified encode or ProRes pipeline.
Neural Engine	🔵 Driver + runtime PM; chip-specific enablement	linux #155 and buffer/lifetime fix linux #191 are merged. Runtime PM autosuspends after 1.5 s by default. The pinned DT enables T8103, T6000/T6001 and T6020/T6021; base M2/T8112 and M1/M2 Ultra remain disabled. Firmware and userspace are separate requirements. The audited asahi/base config fragments do not select CONFIG_DRM_ACCEL_ANE; build the driver with its DRM_ACCEL dependencies before treating DT enablement as an available device. Named-board reports are linked from linux #155; no new test of this product is claimed.

🔌 I/O and security

Feature	Aurora status	Evidence / boundary
USB2 / USB3 host	🔵 DWC3 integrated	Enabled Apple DWC3 board nodes and configured driver. Port combinations, hubs and role swaps need per-board tests.
USB4 / Thunderbolt / USB-C display	🔵 Driver configured; 🟠 board-specific qualification	linux #8, linux #50, linux #184, linux #193 and linux #195 are merged and their merge history reaches the pinned tree. asahi.config now selects CONFIG_USB4=m and CONFIG_USB4_APPLE_SOC=m. linux #46 remains open; linux #64 closed without merge after its work was carried forward. Display, PCIe tunnelling and resume remain board/build specific.
Wi-Fi / Bluetooth	🔵 Wi-Fi board path; 🔵 Bluetooth board path	Broadcom recovery linux #7, AWDL linux #24, J416C recovery linux #167, recovery teardown linux #186 and failed-reset handling linux #192 are merged. Firmware, userspace and named-board test limits remain; this does not qualify every wireless function.
Keyboard / touchpad	🔵 External input drivers	USB HID and Bluetooth drivers are configured; pairing and product-specific external keyboard / mouse tests are not established by the board DTS.
Ethernet / SD / PCIe expansion	⚪ Per-device qualification	PCIe host support is configured. Qualify fitted controllers, adapters and link speeds independently; do not copy support from a sibling board.
SEP / Touch ID	🔵 Integrated driver; 🟠 board-specific acceptance	SEP integration is present through merged linux #42; linux #69 and linux #152 merged into feat/sep. Named sensor, firmware and tested-kernel limits still apply. New firmware-selection/deletion-persistence results on contributor iconidentify/aurora-linux are separate from this working-tree snapshot. External Touch ID keyboards are not qualified by laptop sensor reports.

🔋 Power and complete-system readiness

Feature	Aurora status	Evidence / boundary
Battery / charging / thermals	🔵 Thermal / power foundation	MACSMC power and thermal / hwmon options are configured. Desktop power and thermal behaviour need a board test; battery status is not applicable.
Suspend / resume	🟠 Board-specific qualification	CPU idle and shutdown drivers do not prove a complete suspend / resume cycle. Only the exact boards and development builds named below have cited runtime results.
Installer / complete system	⚪ Release qualification unverified	This is a public kernel source and evidence audit, not a fresh installation or end-to-end hardware test. Record installer, boot chain, kernel, Mesa and firmware revisions together.

🧪 Aurora hardware reports and development branches

No board-specific runtime result was established in the public Aurora PR evidence reviewed for this product. The integrated-source entries above still document concrete implementation; they should be upgraded to hardware results when a repeatable report identifies the exact board and software revision.

PR snapshot: October 8, 2026. Current states and destinations are recorded below. SEP is integrated through #42, while newer downstream Touch ID fixes retain their contributor-kernel scope.
