HibernationFixup.kext

HibernationFixup

Diese Kernel Erweiterung ist ein Plugin für die Lilu.kext, die eine Synchronisierung zwischen RTC-Variablen und NVRAM bereitstellt.

Dieser Kext erkennt die Eingabe von "Hibernate" Power Status und liest den Wert IOHibernateRTCVariables aus der Systemregistrierung aus und schreibt diesen in den NVRAM.

Features

• Enables 'native' hibernation on PC's with hardware NVRAM on 10.10.5 and later.
• 'Native' means hibernation with encryption (standard hibernate modes 3 & 25)
• Enables dumping NVRAM to file /nvram.plist before hibernation or panic

Bootflags

• -hbfxoff : deaktiviert das Laden
• -hbfxdbg : aktiviert Debug Ausgaben
• -hbfxbeta : aktiviert das Laden in noch nicht unterstützten macOS Versionen

Weiter geht es ...

v1.1.2

• Works with EmuVariable

Neue Version ...

v1.1.3

• Panic handling and writing to nvram.plist

Noch einer ....

v1.1.4

• Fix system freeze and black screen when resume after hibernation (Sierra only)

Hier gehts auch weiter ....

v1.1.5

• Added OSBundleCompatibleVersion

v1.1.6

• Requires Lilu 1.1.6
• Compatibility with High Sierra
• PCI Family patch was improved
• New boot-arg hbfx-patch-pci=[comma-separated list of ignored devices] supported

v1.1.7

• Fixes for 1.1.6b (Release was non-working)
• Use pollers to provoke writing of SMC-keys earlier

v1.2.0
( für Lilu 1.2.0 )

v1.2.0

• Cosmetic fixes suggested by vit9696
  

v1.2.5

• Improve auto-hibernate feature: modify next wake time to currentTime + standbyDelay

v1.2.6

• Allow loading on 10.15 without -lilubetaall
• Fix minor typos in code and comments (credits to PMheart)

v1.2.7

• Unified release archive names

v1.2.8

• Fixed memory leaks
• Fixed EmuVariableUefiPresent detection (nvram.plist will be properly saved if EmuVariableUefiPresent == Yes in ioreg)
• Improve auto-hibernate feature: modify next wake time only before regular sleep

v1.2.9

• Improve auto-hibernate feature: if power nap is enabled, hibernation will start after next Maintenance/SleepService wake (standbyDelay value is respected)

v1.3.0

• Do not use recursive iterator to detect EmuVariableUefiPresent (based on panic report analysis)

v1.3.1

• Code refactoring, fix duplicates in log, auto-hibernate can work without power source

v1.3.2

• Fix nvram.plist saving in Catalina, new path is used when the root folder is not writable: /System/Volumes/Data/nvram.plist

v1.3.3

• Improve auto-hibernate feature: support standby and autopoweroff separately (with respective delay). Immediate hibernate is possible with zero delay.

v1.3.4

• Improve auto-hibernate feature: correct next wake time disregarding the current sleep phase.
• Added constants for 11.0 support.
