OC integration
Rev 5119 commit 620401d
Included OcQuirks and OpenRuntime into Clover repository.
The drivers will be built at Clover compilation.
commit 60901993b
OcQuirks driver and plist now excluded. Now Quirks included into config.plist as separate section
## Config.plist Quirks structure
Set default and most recommended values
<key>Quirks</key>
<dict>
<key>AvoidRuntimeDefrag</key>
<true/> -- recommended for all except native Apple
<key>DevirtualiseMmio</key>
<false/> -- may be useful for Z390
<key>DisableSingleUser</key>
<false/> -- prohibit using Single User Mode. If you are paranoiac.
<key>DisableVariableWrite</key>
<false/> -- prohibit write to NVRAM. If you are paranoiac.
<key>DiscardHibernateMap</key>
<false/> -- in some rare cases memory after hibernation can be
wrong mapped. Usually no.
<key>EnableSafeModeSlide</key>
<false/> -- safe mode (-x) by default will use slide=0. You may set
other value if enable. Mojave crashes with <true>. Ventura works.
<key>EnableWriteUnprotector</key>
<true/> -- clear memory protect bit. See note below.
<key>ForceExitBootServices</key>
<false/> -- never used
<key>MmioWhitelist</key>
<array> -- list of memory regions to protect. Only good hackers
know why.
<dict>
<key>Address</key>
<integer>4275159040</integer>
<key>Comment</key>
<string>Haswell: SB_RCBA is a 0x4 page memory region, containing SPI_BASE at 0x3800 (SPI_BASE_ADDRESS)</string>
<key>Enabled</key>
<false/>
</dict>
<dict>
<key>Address</key>
<integer>4278190080</integer>
<key>Comment</key>
<string>Generic: PCI root is a 0x1000 page memory region used by some firmwares</string>
<key>Enabled</key>
<false/>
</dict>
</array>
<key>ProtectMemoryRegions</key>
<false/> -- set true if you use CSM, if your videocard if not UEFI
<key>ProtectSecureBoot</key>
<false/> -- rarely used with InsideH2O
<key>ProtectUefiServices</key>
<false/> -- needed for VMWare if it will be used with hackintosh
bootloader, usually no.
<key>ProvideCustomSlide</key>
<false/> -- if you see OCABC: Only N/256 slide values are usable
then set this to true
<key>ProvideMaxSlide</key>
<integer>0</integer> -- for the case above set a value between 1 and 254.
Never used.
<key>RebuildAppleMemoryMap</key>
<false/> -- see note below
<key>ResizeAppleGpuBars</key>
<integer>-1</integer> -- only for RX6800 if set in BIOS Resizable Pci Bar,
which is incompatible with MacOS
<key>SetupVirtualMap</key>
<true/> -- always true
<key>SignalAppleOS</key>
<false/> -- always false. May be assumed for OpenCore that
cant start windows.
<key>SyncRuntimePermissions</key>
<true/> -- always true
<key>FuzzyMatch</key>
<false/> -- for system Snow Leopard it may be true
<key>KernelCache</key>
<string>Auto</string> -- (Auto, Cacheless, Mkext, Prelinked) for system
Lion (10.7). No more.
<key>AppleXcpmExtraMsrs</key>
<false/> -- support for XCPM for non-native CPU like Haswell-E
<key>AppleXcpmForceBoost</key>
<false/> -- set maximum P-state for CPU, maximum frequency.
Install water cooler for this case
<key>DisableIoMapper</key>
<false/> -- switch off VT-d. It will be better to drop or
replace DMAR table. Dont set this if you want Monterey
<key>DisableLinkeditJettison</key>
<true/> -- fix Lilu bug
<key>DummyPowerManagement</key>
<false/> -- block AppleIntelCpuPowerManagement because you have
locked 0xE2. Should be resolved other way.
<key>ExternalDiskIcons</key>
<false/> -- usual patch from KextPatches section
changing "External" -> "Internal"
<key>IncreasePciBarSize</key>
<false/> -- never use
<key>PowerTimeoutKernelPanic</key>
<false/> -- never use
<key>ThirdPartyDrives</key>
<false/> -- usual patch "Enable Trim on Non-Apple."
changing "Apple" -> ""
<key>XhciPortLimit</key>
<false/> -- usual patch extended maximum XHCI ports because
Apple has limit to 15. Don't do this!
The extended limit will break the system.
Create LegacyUSB.kext to use 15 ports without
needless ports.
<key>ProvideCurrentCpuInfo</key>
<false/> -- dangerous patch for the AlderLake CPU.
Use if needed with precautions.
</dict>
Note! If you system contains MATS table then you should set such quirks
EnableWriteUnprotector - False
RebuildAppleMemoryMap - True
SyncRuntimePermissions - True
Otherwise contrary.
Booting macOS 11 and macOS 12 OpenRuntime.efi is need.
Rev 5142+ Using new OpenRuntime.efi.
There is incompatibility with older version. Clover before 5142 requires OpenRuntime.efi version 1.1 while 5142+ requires version 1.2.
What to do if you sometime want to reboot with older version?
Slice made special folder drivers/5142 where OpenRuntime-v12.efi is placed. And common folder drivers/UEFI contains OpenRuntime-v11.efi.
How it works ⤵︎
Old Clover not see the folder 5142 and uses common folder drivers/UEFI and read here openRuntime-v11.efi.
New Clover see the folder drivers/5142 and read here new OpenRuntime-v12.efi which is in priority in the version.
That's all!
OpenCorePkg repos used by Clover ☞ OpenCorePkg is used by Clover
OpenCorePkg is not same as original. Based on OpenCore 0.7.5 it is improved up to latest version. Clover uses some part of the package delegating kext injecting and patching abilities to OC libraries. Big respect to vit9696 for these libraries. Clover keeps own syntax for kernel and kext patching and converted them to OC syntax Conversion rulez but the method for binary patching in the OC library is replaced by Clover's method because it has more possibilities.
Some new quirks implemented in new OC versions have no analogs in the Clover's config.plist because they are very specific for rare hardware. If you really need them then search how to do the same by common kext patching. Usually the new quirk is just a shortcut to one kernel or kext patch.
