This section is used for booting and provides firmware fixes in relation to boot.efi. The sub-sections are explained below.

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:

Quirks	Value	Notes
AvoidRunTimeDefrag	YES	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*
DevirtualiseMmio	YES	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.*
EnableSafeModeSlide	YES	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.*
ProvideCustomSlide	YES	Provide custom KASLR slide on low memory. This option forces macOS to use a pseudo random value among the available ones.
SetupVirtualMap	YES	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.*
RebuildAppleMemoryMap	YES	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.*
SyncRuntimePermission	YES	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.*
ProvideMaxSlide	0	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:

Devices	Key	Value	Type	Notes
PciRoot(0x0)/Pci(0x2,0x0)	AAPL,ig-platform-id	00009B3E	DATA	Specifies ig-platform-id which enables IGPU Graphics acceleration and support.
	device-id	9B3E0000	DATA	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-fix	01000000	DATA	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-support	01000000	DATA	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.*

	framebuffer-stolenmem	00003001 00002002	DATA	Specifies stolenmem. This is a memory which is reserved for the IGPU. 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. *However, few 4K/UHD/QHD Laptops such as Lenovo Yoga, may require BIOS unlocking.*
	framebuffer-unifiedmem	00000080 000000C0	DATA	Defines VRAM size. 00000080 Change the VRAM to 2048MB in About This Mac, Display Tab and in System Report>Graphics/Displays Tab. 000000C0 Change the VRAM to 3072MB in About This Mac, Display Tab and in System Report>Graphics/Displays Tab. *This property doesn't have any affect with the actual VRAM and is purely cosmetic.*
	hda-gfx	onboard-1	STRING	Sets hda-gfx to onboard-1 on IGPU. This property provides HDMI/DP function and can also fix crash issue when Hot plugging.
PciRoot(0)/Pci(0x1f,3)	hda-gfx	onboard-1	STRING	Sets hda-gfx to onboard-1 on HDEF. This property provides HDMI/DP function and can also fix crash issue when Hot plugging.
	layout-id	xx	NUMBER	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.

This includes Basic integrity checking but also attempts to build a trusted boot chain.
BootProtect	None Boostrap	Attempt to provide bootloader persistence None Enables usage of Bootstrap.efi in the directory EFI/OC/Bootstrap instead of BOOTx64.efi. This setting is helpful for users using rEFInd to boot or avoid BOOTx64.efi overwrites from Windows. Bootstrap *For this option to work RequestBootVarRouting is required to be enabled.* *Use of Bootstrap option will also enable "OpenCore" instead of UEFI: OS followed by your drive name in Boot Menu.*
DmgLoading	Disabled Signed Any	Define Disk Image (DMG) loading policy used for macOS Recovery. Disabled Disables loading of DMG images. Disabled policy will still let macOS Recovery to load in most cases as there usually are boot.efi files compatible with Apple Secure Boot. Manually downloaded DMG images stored in com.apple.recovery.boot directories will not load. Signed Enables only Apple-signed DMG images will load. Due to Apple Secure Boot design Signed policy will let any Apple-signed macOS Recovery to load regardless of Apple Secure Boot state, which may not always be desired. *It's recommended to set this option to "Signed" to avoid issues.* Any Enables any DMG images will mount as normal filesystems. Any policy is strongly not recommended and will cause a boot failure when Apple Secure Boot is activated.
SecureBootModel	Default Disabled	Defines Apple Secure Boot hardware model. Sets Apple Secure Boot hardware model and policy. Specifying this value defines which operating systems will be bootable. Operating systems shipped before the specified model was released will not boot. Default Enables Default Secure Boot.

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:

Devices	Key	Value	Type	Notes
PciRoot(0x0)/Pci(0x2,0x0)	AAPL,ig-platform-id	0000528A	DATA	Specifies ig-platform-id which enables IGPU Graphics acceleration and support.
	enable-cdclk-frequency-fix	01000000	DATA	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-fix	01000000
	enable-dvmt-calc-fix	01000000	DATA	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-fix	01000000	DATA	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-support	01000000	DATA	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.*
	framebuffer-con1-alldata	01050900 00040000 87010000
	framebuffer-con1-enable	01000000		Enables framebuffer connector 1. For more information, refer to the connector type guide linked below.

	framebuffer-con3-has-lspcon*	01000000		Adds framebufer-conX-has-lspcon property to IGPU.
	framebuffer-con3-preferred-lspcon-mode*	01000000 00000000		Adds framebuffer-conX-preferred-lspcon-mode property to IGPU. Specifies a mode for your onboard LSPCON adapter. 01000000 PCON, DP to HDMI 2.0 00000000 LS, DP to HDMI 1.4 If this property is not specified, the driver assumes that PCON mode is preferred. If your connector is different, you must set this property to the respective connector.
	framebuffer-fbmem	00009000 00000003	DATA	Specifies framebuffer memory size. This is a memory which is reserved for the framebuffer. 00009000 Sets framebuffer memory size to 9MB 00000003 Sets framebuffer memory size to 48MB

	framebuffer-stolenmem	00003001 00002002	DATA	Specifies stolenmem. This is a memory which is reserved for the IGPU. 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. *However, few 4K/UHD/QHD Laptops such as Lenovo Yoga, may require BIOS unlocking.*
	framebuffer-unifiedmem	00000080 000000C0	DATA	Defines VRAM size. 00000080 Change the VRAM to 2048MB in About This Mac, Display Tab and in System Report>Graphics/Displays Tab. 000000C0 Change the VRAM to 3072MB in About This Mac, Display Tab and in System Report>Graphics/Displays Tab. *This property doesn't have any affect with the actual VRAM and is purely cosmetic.*
	hda-gfx	onboard-1	STRING	Sets hda-gfx to onboard-1 on IGPU. This property provides HDMI/DP function and can also fix crash issue when Hot plugging.
PciRoot(0)/Pci(0x1f,3)	hda-gfx	onboard-1	STRING	Sets hda-gfx to onboard-1 on HDEF. This property provides HDMI/DP function and can also fix crash issue when Hot plugging.
	layout-id	xx	NUMBER	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.

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?

STRING

Adds boot args which provides several functions.

-v

Enables verbose mode. Helpful to track the installation progress or when booting.

We recommend to use this boot arg.

Once you're done with the installation and post installation, you can disable this boot arg.

-cdfon

Enables CoreDisplayFixup functionality via WhateverGreen.kext.

If your Laptop has a 4K/UHD/QHD panel, you'll need to use this boot arg.

alcid=xx

Sets Layout ID for AppleALC.

The xx represents the layout ID for your codec.

wegnoegpu

Disables discrete Graphics.

Disables discrete Graphics (NVIDIA or AMD), helpful in case of Dual GPU Laptops.

This boot arg is a temporary solution. It's recommended to patch your DSDT and related SSDTs to disable the discrete Graphics for a better power management and improved battery performance.

debug=0x100

This disables macOS's watchdog which helps prevents a reboot on a kernel panic.

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
