BootCamp Performance Control 0.5.0-rc.2

BootCamp Performance Control 0.5.0-rc.2

This release candidate expands BCPC's capability-driven thermal-control architecture while keeping the fail-closed hardware safety model.

Highlights

• Gaming Optimised uses the global Supported Intel Mac processor policy:
  • Maximum Processor State AC/DC: 95% / 95%
  • Processor Boost AC/DC: Disabled / Disabled
• SupportedIntelMac is determined from detected Apple hardware + Intel CPU, not an exact Mac-model whitelist.
• Fan-write eligibility is independent and selected from a fresh live AppleSMC capability fingerprint.
• Production capability families:
  • PerFanModeFloat32
  • bounded GlobalMaskFpe2
• Dynamic topology is discovered from live FNum.
• Maximum Safe RPM is derived from fresh live F{i}Mx.
• Pre-write transaction journaling, deterministic partial-write recovery and Apple Auto rollback/recovery are hardened.
• The obsolete model-validation / tested-vs-untested UI classification has been removed.

Physical validation evidence

MacBookPro16,1 remains physically validated end-to-end for PerFanModeFloat32.

MacBookPro12,1 has physically qualified the one-fan GlobalMaskFpe2 write/readback/Apple Auto round trip.

Physical validation records are evidence for observed mechanisms. They are not runtime model whitelists.

Safety boundaries

• Two-fan GlobalMaskFpe2 (FS! = 0003) still requires its own BCPC-owned physical qualification.
• Unknown, malformed or mismatched capability fingerprints fail closed.
• FNum = 0 remains a valid passive/fanless read-only topology.
• BCPC does not expose arbitrary SMC writes, minimum-RPM control or a user-defined RPM slider.
• Exact Mac model identity does not grant normal processor or fan-write permission.
• The experimental native BootCampSmc write transport is not claimed as physically write-qualified and is not the production dependency.
• The release ZIP does not bundle Macs Fan Control, applesmc.sys, BootCampSmc.sys, driver packages or other proprietary third-party binaries.

The currently validated compatibility environment uses a separately installed copy of Macs Fan Control 1.5.16 / AppleSMC driver 1.0.7.0.

Stable v0.4.0 remains the latest stable release. v0.5.0-rc.2 is a pre-release intended for controlled compatibility testing.

BootCamp Performance Control 0.5.0-rc.1

0.5.0-rc.1 — T2 fan-control family candidate

This is a pre-release. Stable remains 0.4.0.

Highlights

• Gaming Optimised CPU target is global for SupportedIntelMac: Maximum Processor State 95% / 95%, Boost disabled on AC/DC.
• Fan control is additive; CPU-only Gaming remains available when the fan backend is unavailable or cannot be safely owned.
• Dynamic fan topology is discovered from live FNum.
• Fan writes are enabled only for the verified runtime MMIO + FNum + per-fan FLT4 / Md / Tg capability family.
• Maximum Safe RPM targets always come from fresh live F{i}Mx.
• Crash/startup fan recovery and fan-only resume are generalized beyond an exact-model runtime gate.
• Legacy schema-v1 downgrade recovery remains for the exact two-fan MacBookPro16,1 path.

Physical validation

End-to-end physically validated on:

• MacBookPro16,1
• MacBook Pro 16-inch (2019)
• Apple T2
• Windows 10 Boot Camp

Validated lifecycle:

• read-only capability preflight,
• Maximum Safe RPM apply and read-back,
• CPU 95 / 95, Boost 0 / 0,
• normal FANS -> POWER Restore,
• forced-process termination,
• automatic startup Apple Auto fan recovery,
• processor snapshot preservation,
• fan-only resume without snapshot replacement,
• final exact processor Restore.

Observed live fan maxima on the reference machine:

• Fan 0: 5616 RPM
• Fan 1: 5200 RPM

Other machines are not claimed physically validated merely because they contain Apple T2. Fan-write eligibility depends on the live guarded capability fingerprint.

Safety boundary

• T1 fpe2 / FS! writes remain disabled.
• Closed production write surface: discovered F0..F9 Md/Tg only.
• No arbitrary SMC keys.
• No minimum-RPM controls.
• No manual fan-speed slider.
• No undervolting or CPU MSR writes.
• No firmware or display-timing modifications.
• BCPC does not bundle Macs Fan Control, applesmc.sys, or the experimental native BootCampSmc driver.

Compatibility backend

The physically validated environment uses a separately installed:

• Macs Fan Control 1.5.16 (Build 693)
• AppleSMC driver file version 1.0.7.0

Close the Macs Fan Control application before BCPC takes fan ownership.

See README.md, docs/FAN-CONTROL.md, docs/HARDWARE-COMPATIBILITY.md, and docs/0.5.0-rc.1-HARDWARE-VALIDATION.md for details.
