2015 MacBook Pro (MacBookPro11,5) on Linux
| File | What’s in it |
|---|---|
| hardware.md | Start here. Distro-agnostic: kernel parameters and why, radeon vs amdgpu, sleep/hibernate results with measured power, Bluetooth, camera, fans/SMC, troubleshooting |
| omarchy.md | Current install: Limine/UKI config files, Omarchy-owned files, lid/logind, decisions, open items |
| linux-mint.md | Previous install: GRUB/initramfs-tools, recovery, Ubuntu MTRR kernel build, Cinnamon extras |
| sleep-test.sh | Measures battery drain of s2idle / deep / awake (any systemd distro) |
| bluetooth/bt-fix.sh | Fixes the Bluetooth chip hanging at boot (any systemd distro) |
| wifi/ | Sleep hook that unloads Wi-Fi before deep sleep and hibernate (needed for hibernate); recovery script for when Wi-Fi dies anyway |
| kernel/ | amdgpu patch for deep sleep + module build/install scripts + a guard that falls back to s2idle and notifies you after a kernel update; MTRR resume patch (fixes the slow wake from deep sleep) + Ubuntu kernel build script |
| fans/ | Smoothed fan daemon: a fallback only, since the SMC’s own fan control was fine on Omarchy |
In short: always use intel_iommu=off and nvme_core.default_ps_max_latency_us=0. Then choose:
- radeon, for real sleep (deep, 0.2 W) and no Vulkan
- amdgpu +
amdgpu.ip_block_mask=0x7f+mem_sleep_default=s2idle, for Vulkan but only “sleep” at about 22 W - amdgpu +
amdgpu.ip_block_mask=0x7f+ the patched module from kernel/amdgpu-si-reset-on-init.patch, for Vulkan and real sleep (deep, ~0.5 W). It needs a rebuild after each kernel update, until the fix is upstream.
Apply bluetooth/bt-fix.sh either way.
