MmioWhitelist
Designed to be filled with plist dict values, describing addresses critical for particular firmware functioning when DevirtualiseMmio quirk is in use.

Note:
For a Comet Lake Laptop, this section requires no modification and will remain untouched.


Quirks
This section allows to apply certain Booter quirks.

The required Booter Quirks for a Comet Lake Laptop includes:

QuirksValueNotes
AvoidRunTimeDefragYES
  • Fixes certain UEFI runtime services such as date time, NVRAM, power control, etc.
  • Apart from Apple and VMware, this quirk is required by rest of the firmwares
DevirtualiseMmioYES
  • Remove runtime attribute from select MMIO regions.
  • This option reduces stolen memory footprint from the memory map by removing runtime bit for known memory regions.
EnableSafeModeSlideYES
  • Patch bootloader to have KASLR enabled in safe mode.
  • This quirk requires ProvideCustomSlide to be enabled.
  • This quirk can be helpful if you're unable to boot into safe mode.
ProvideCustomSlideYES
  • Provide custom KASLR slide on low memory.
  • This option forces macOS to use a pseudo random value among the available ones.
SetupVirtualMapYES
  • Setup virtual memory at SetVirtualAddresses.
  • Fixes several virtual address issues and tends to fix early Kernel Panics.
  • The necessity of this quirk is determined by early boot failures. Currently, new firmware with memory protection support (such as OVMF) do not support this quirk.
RebuildAppleMemoryMapYES
  • Generates Memory Map which is compatible with macOS.
  • Since several types of firmware come with incorrect memory protection tables, this quirk often comes paired with SyncRuntimePermissions.
SyncRuntimePermissionYES
  • Update memory permissions for runtime environment.
  • The need for this quirk is indicated by early boot failures. Only firmware released after 2017 is typically affected.
ProvideMaxSlide0
  • Provide maximum KASLR slide when higher ones are unavailable.

Note:
The values which have been not discussed above, that will remain disabled.


DeviceProperties



This section is used for adding device properties. This includes PCI Devices information such as Graphics, Audio, WiFi, Ethernet and other controllers.

The required Device properties for a Comet Lake Laptop includes:

DevicesKeyValueTypeNotes
PciRoot(0x0)/Pci(0x2,0x0)AAPL,ig-platform-id00009B3EDATA
  • Specifies ig-platform-id which enables IGPU Graphics acceleration and support.
device-id9B3E0000DATA
  • Sets Device ID for Comet Lake CPUs
dpcd-max-link-rate
  • 06000000
  • 0A000000
  • 14000000
  • 1E000000
DATA
  • Sets link rate type.
All the possible values for link rate are listed below.

06000000

  • Required for Laptops having 1080p Display, (RBR)
0A000000
  • Required for Laptops having 1080p Display, (HBR)
14000000
  • Required for Laptops having 4K Display, (HBR2)
1E000000
  • Required in case if the Laptop has more refresh rate than 60Hz.
  • This can fix display glitch after sleep/wake (HBR3)
enable-dpcd-max-link-rate-fix01000000DATA
  • Fixes invalid maximum link rate
  • This property on IGPU can fix the invalid link rate otherwise a kernel panic can occur due to a division-by-zero.
  • Usually required by Laptops with Sharp Display and more refresh rate.
enable-lspcon-support01000000DATA
  • Enables LSPCPN driver support to enable DisplayPort to HDMI 2.0 output on IGPU.
  • Coffee Lake are typically quipped with a HDMI 2.0 port. This port could be either tied to IGPU or DGPU. Intel UHD Graphics, does not provide native HDMI 2.0 output, so in order to solve this issue, OEMs adds an additional hardware names LSPCOn on the motherboard to convert DisplayPort into HDMI 2.0
  • LSPCON works in either Level Shifter (LS) or Protocol Converter (PCON) mode. When the adapter works in LS mode, it is capable of producing HDMI 1.4 output via DisplayPort, while in PCON mode, it could provide HDMI 2.0 output. Some onboard LSPCON adapters have been configured in the firmware to work in LS mode by default, resulting a black screen on handling HDMI 2.0 connections.
  • WEG provides driver support for the onboard LSPCON by automatically configuring the adapter to run in PCON mode on new HDMI connections, which tends to solves the black screen issue.
  • LSPCON driver is only applicable for Laptops with HDMI 2.0 routed to IGPU.
  • If your HDMI 2.0 is routed to IGPU and is working properly right now, you don't need to enable this driver, as your onboard LSPCON might have been already configured in the firmware to work in PCON mode.
  • This property can also provide HDR signaling over HDMI.

DeviceProperties



This section is used for adding device properties. This includes PCI Devices information such as Graphics, Audio, WiFi, Ethernet and other controllers.

The required Device properties for an Ice Lake Laptop includes:

DevicesKeyValueTypeNotes
PciRoot(0x0)/Pci(0x2,0x0)AAPL,ig-platform-id0000528A DATA
  • Specifies ig-platform-id which enables IGPU Graphics acceleration and support.
enable-cdclk-frequency-fix01000000DATA
  • Adds enable-cdclk-frequency-fix property to IGPU to support all valid Core Display Clocl (CDCLK)
  • Prevents kernel panic due to an unsupported CD clock decimal frequency.
  • Apple's Graphics driver expects that the firmware has already set the clock frequency to either 652.8MHz or 648MHz (actual value depends on the hardware), but few laptops set it to a much lower value such as 172.8MHz, and a kernel panic can occur.
enable-cfl-backlight-fix01000000
enable-dvmt-calc-fix01000000DATA
  • Adds the enable-dvmt-cal-fix property to IGPU to fix the calculation of the amount of DVMT pre-allocated memory on Ice Lake Laptops.
  • Prevents kernel panic due to incorrect calculation of DVMT pre-allocated memory.
  • Apple's Graphics driver reads the DVMT value set in the BIOS or the firmware and uses a "magic" forumula to calculate the amount of memory in bytes. Unfortunately, the forumal only works for a pre-allocated memory size that is a multiple of 32MB. By default, on Ice Lake Laptops, the DVMT is set to 60MB where the framebuffer controller ends up with initializing the stolen memory manager with an incorrect amount of pre-allocated memory.
dpcd-max-link-rate
  • 06000000
  • 0A000000
  • 14000000
  • 1E000000
DATA
  • Sets link rate type.
All the possible values for link rate are listed below.

06000000

  • Required for Laptops having 1080p Display, (RBR)
0A000000
  • Required for Laptops having 1080p Display, (HBR)
14000000
  • Required for Laptops having 4K Display, (HBR2)
1E000000
  • Required in case if the Laptop has more refresh rate than 60Hz.
  • This can fix display glitch after sleep/wake (HBR3)
enable-dpcd-max-link-rate-fix01000000DATA
  • Fixes invalid maximum link rate
  • This property on IGPU can fix the invalid link rate otherwise a kernel panic can occur due to a division-by-zero.
  • Usually required by Laptops with Sharp Display and more refresh rate.
enable-lspcon-support01000000DATA
  • Enables LSPCPN driver support to enable DisplayPort to HDMI 2.0 output on IGPU.
  • Coffee Lake are typically quipped with a HDMI 2.0 port. This port could be either tied to IGPU or DGPU. Intel UHD Graphics, does not provide native HDMI 2.0 output, so in order to solve this issue, OEMs adds an additional hardware names LSPCOn on the motherboard to convert DisplayPort into HDMI 2.0
  • LSPCON works in either Level Shifter (LS) or Protocol Converter (PCON) mode. When the adapter works in LS mode, it is capable of producing HDMI 1.4 output via DisplayPort, while in PCON mode, it could provide HDMI 2.0 output. Some onboard LSPCON adapters have been configured in the firmware to work in LS mode by default, resulting a black screen on handling HDMI 2.0 connections.
  • WEG provides driver support for the onboard LSPCON by automatically configuring the adapter to run in PCON mode on new HDMI connections, which tends to solves the black screen issue.
  • LSPCON driver is only applicable for Laptops with HDMI 2.0 routed to IGPU.
  • If your HDMI 2.0 is routed to IGPU and is working properly right now, you don't need to enable this driver, as your onboard LSPCON might have been already configured in the firmware to work in PCON mode.
  • This property can also provide HDR signaling over HDMI.

  • Prevents kernel panic due to less DVMT size set in BIOS/UEFI.
00003001
  • Sets framebuffer stolenmem size to 19MB
  • Usually relevant for Laptops where the DVMT-prealloc cannot be set due to hidden settings under BIOS/UEFI.
00002002
  • Sets framebuffer stolenmem size to 34MB
  • Usually relevant for 4K/UHD/QHD panel where the DVMT cannot be set due to hidden settings under BIOS/UEFI and variables cannot be modified using UEFI shell method.

  • This property provides HDMI/DP function and can also fix crash issue when Hot plugging.
PciRoot(0)/Pci(0x1f,3)hda-gfxonboard-1STRING
  • Sets hda-gfx to onboard-1 on HDEF.
  • This property provides HDMI/DP function and can also fix crash issue when Hot plugging.
layout-idxxNUMBER
  • Sets Layout ID for your Audio Codec.
  • The xx represents the layout ID for your codec.
  • Although, there's a new way to set Layout ID. However, few Laptops still require it.


Note:
To find the corresponding connector index of your HDMI port, follow the guide below.


If you're having a 2K/4K monitor, you might need temporarily to enable the infinite loop fix (-igfxhdmidivs) before connecting a HDMI monitor to your build, otherwise the system will just hangs, or you won't be able to run the IORegistryExplorer and find the connector index.

*Sets LSPCON to connector 3.

*If your connector is different, you must set this property to the respective connector.

The SSDTs are bundled with OpenCore package.
agree, but we have to put inside EFI the *.aml file

for example i need the SSDT-EC-USBX.aml , how to obtain this ?
should i copy the raw code from github to a new compilation an save it as ACPI file with the the name of the Acpi Sample?

at patching DSDT and SSDT, what does this mean : ”Table Signature*” ?

on config.plist for OC the PATCH has no DSDT table. Were to add this? under ACPI/PATCH as a Children or OpenCore ->ACPI -> New Blank Entry?

this patches will patch what ? the DSDT ? if yes, then DSDT wll remain unpatched via MacIASL?
Thank u

You'll find it in the release folder of OC. You'll need to compile it.
i have managed to compile thoes 3 SSDT's and put them to ACPI. managed to boot the installer .
stil i did not attached the DSDT to ACPI . allso did not applied any patches (hot patch) to ACPI , i do not know how to do that.
