sigil-kernel's third Apple Silicon HAL batch ships 12 new HAL components — Apple audio (CS35L41), SMBus battery/charger (BQ40Z50/BQ25890H), GPT block device, USB-PD (100W EPR), Touch ID/Face ID biometric, ISP camera (1080p NV12), Thunderbolt 4/USB4 retimer, plus PowerPC: G5 SATA (AHCI-lite), HyperTransport (3-node), USB OHCI, FireWire OHCI, IDE/ATA, Screamer/Burgundy audio. The HAL now covers 36 components across M1 and G3/G4/G5. (sigil-kernel c0bac35, 26273db, bd1b695, 84421c0, 739d21e, 5eb4aa3)
HAL status
After three batches, the Apple Silicon HAL covers the complete M1 bring-up surface. PowerPC (G3/G4/G5) is fully covered for legacy Mac hardware. Every component is QEMU-verified against its hardware model. The HAL design is uniform: each .sg file implements an init, a set of operation verbs, and a PASS/FAIL screendump that the harness can read. No component ships without a green harness run.
