DSDT Patching

Cassio · November 1, 2011

How to apply a patch using DSDT Editor

If you will apply several patches you can compile only once, after all patches are applied.

When applying a patch, check the before/after tabs and try to understand what is being changed and why.

Important: always start from an original DSDT. Don't use "extract DSDT" if you booted using a patched dsdt.aml from other PC. If you can't boot without a patched DSDT, use Windows or Linux to extract the original DSDT from BIOS.

If you update BIOS, most likely you will have to patch DSDT again, so it's a good idea to create a full patch, with all needed patches (separated by ";"), like the many examples here.

Patches

DSDT Patch Request

Power management:

If AppleIntelCPUPowerManagement doesn't work (need to use NullCPUPowerManagement) even if you enable GenerateCStates and GeneratePStates in Chameleon, check if AppleLPC is loaded (run "kextstat" command in terminal), if it's not, apply one of the LPC patches according to your chipset (desktop/laptop ICH7, ICH8, ICH9, ICH10, Nehalem, Sandy Bridge).

If you get "No HPET(s) available" kernel panic you may need the HPET patch. The example is used on Gigabyte mobos, but it may also be needed in other mobos and laptops (adapt _CRS to return the ResourceTemplate right above).

For many Sandy Bridge systems it's also necessary to patch AppleIntelCPUPowerManagement.

About power management http://Olarila.com/forum/viewtopic.php?f=18&t=1703

USB problems:

There are many USB patches, EHCI, UHCI, ICH9 USB sleep, EHCI sleep/ownership, some are generic, some are organized by chipset. If you have problems with USB ports, if you see errors or warnings in kernel log about EHCI or UHCI, you can try these patches.

Sleep problems:

Problems with sleep are usually related to power management and USB.

If the system goes to sleep and wakes immediately, look for "Wake reason" in kernel log and edit method _PSW or remove _PRW from that device in DSDT.

CMOS reset:

Apply the RTC patch.

If you have CMOS reset after sleep/wake/reboot in Lion, you need to patch AppleRTC.

Audio:

You can use HDEF (or AZAL to HDEF if you already have device AZAL) and a codec patch (ALC*) if you will use a patched AppleHDA, or if you just want to have audio information in System Profiler.

Make sure layout-id in DSDT (hex) coincides with LayoutID in AppleHDA (decimal).

DTGP is required by many patches, so you will probably need it.

IRQs is a "generic" patch, it's always used. In some cases more IRQs are added to device HPET, compare patches for various chipsets.

SBUS (SMBUS) is used to get SMBus kexts loaded.

Shutdown patches are BIOS specific, apply if the PC doesn't turn off properly.

There are other hardware specific and some "cosmetic" patches (only fix warning and remark messages in compilation, but aren't really necessary).

Sorry, I am a total noob in DSDT stuff and patching... . Here is my question if anyone would explain it clearly to me:

I have a GA-965P-S3 mainboard. Should i just apply the patch "GA-965P-S3" to my original extracted DSDT, or do I also have to apply "AZAL to HDEF" and "ALC888" and maybe "HDEF-GIGABYTE-ALC888" too?

Does the order of applying patches actually matter?

I looked in my original (untouched) DSDT, and found 2 instances of the word "AZAL", by the way.

So please explain to me in a way that I can identify my sound problem.

Thanks in advance.

artur-pt · May 28, 2015

hello

probably the patch for ur mobo .. already have the sound fix

anyway is not only dsdt patch u need .. u need also a patched applehda to ur alc

that info is all here in forum

good hack

Hi. I know this is an old thread but I just wanted to post to say thank you for a DSDT patch that worked on my brand new HP Envy 17-ae100 laptop. It's has a CoffeeLake CPU and when I shut down macOS, the OS would shut down but the laptop did not power down (fans and LED lights stayed on.). The Intel Shutdown patch worked. Neither MaLdOn nor RehabMan had fixes that worked, but yours did. Way to go!!!!

Nice

Intel Shutdown is a Hybrid with common patch + gigabyte shutdown patch xD

Enjoy

If a user finds a "patch pack" for their motherboard, does it matter what bios version is installed *or* what motherboard revision they have, for example 1.0, 1.1, 3.3, etc? I am asking because there are differences between bios versions and motherboard revisions.

MaLd0n · August 15, 2018

the patch extract and apply in current version

zeg66 · August 15, 2018

if you are referring to dsdt/ssdt extraction via Clover/F4, yes you are absolutely right. However I was referring to a ready-made dsdt patch-pack for a specific motherboard, for example GA-965P-S3 (three revisions 1.0, 1.1, 3.3). Maybe it doesn't matter?

same patch work for all revisions

zeg66 · August 15, 2018

is there a utility that shows if a dsdt or ssdt (in efi/clover/acpi/patched) has been actually loaded?

MaLd0n · August 15, 2018

u need extract dsdt and check if have patches

Hi, given that the dsdt editor program is no longer available, is it possible to get information on how to patch the new MaciASL program?

MaLd0n · July 6, 2019

[ref]prist[/ref], is a same patches, work with maciasl too

prist · July 6, 2019

Thanks MaLd0n for the reply, but the problem is that I don't know how to apply it, I didn't find any video or reference, if by chance it's written in the forum can you paste the link?

Thank you

Maybe it will be the age, do I have to turn the dsdt you sent me into txt, copy the content and paste it for compilation?

                               Divide (Local1, 0x0A, Local2, Local3)

This patches fine but the following does not...

ThermalZone (BATZ)
       {
           Method (_PSV, 0, NotSerialized)  // _PSV: Passive Temperature
           {
               Return (GETP (Zero, 0x05))
           }

           Method (_PSL, 0, NotSerialized)  // _PSL: Passive List
           {
               Return (PSL ())
           }

           Name (_TSP, 0x012C)  // _TSP: Thermal Sampling Period
           Name (_TC1, One)  // _TC1: Thermal Constant 1
           Name (_TC2, 0x02)  // _TC2: Thermal Constant 2
           Method (_CRT, 0, Serialized)  // _CRT: Critical Temperature
           {
               Return (0x0FAC)
           }

           Method (_TMP, 0, Serialized)  // _TMP: Temperature
           {
               Store (0x0AAC, Local0)
               Store (0x0AAC, Local1)
               Acquire (\_SB.PCI0.LPCB.EC0.ECMX, 0xFFFF)
               If (\_SB.PCI0.LPCB.EC0.ECRG)
               {
   ------   Store (B1B2(\_SB.PCI0.LPCB.EC0.CBT0,\_SB.PCI0.LPCB.EC0.CBT1), Local1)
               }

               Release (\_SB.PCI0.LPCB.EC0.ECMX)
               Store (GTTP (0x05, Local1, 0x0AAC, 0x0FA2), Local0)
               If (SETM (0x05, Local0, Zero, Zero))
               {
                   Notify (BATZ, 0x81)
               }

               Return (Local0)

This give error. Object is not accessible from this scope (B1B2) and if I don't patch I get error Object does not exist (/SB.PIC0.LBPC.ECO.CBT) because I patched it in EC0.

Scope _TZ--BATZ--_TMP

EDIT....

So I managed to fix this error by adding Method (B1B2, 2, NotSerialized) { Return(Or(Arg0, ShiftLeft(Arg1, 8))) } to the _TZ scope

Everything else went good
