# SSDTs: The easy way
|
|
|
|
So here we'll be using a super simple tool made by CorpNewt: [SSDTTime](https://github.com/corpnewt/SSDTTime)
|
|
|
|
What this tool does is, it dumps your DSDT from your firmware, and then creates SSDTs based off your DSDT. **This must be done on the target machine running either Windows or Linux**
|
|
|
|
## So what **CAN'T** SSDTTime do
|
|
|
|
* **SSDT-PNLF**:
|
|
* Need to be configured to your system
|
|
* **SSDT-GPI0**:
|
|
* Need to be configured to your system
|
|
* **USBX SSDT**:
|
|
* This is included on sample SSDTs but SSDTTime only makes the SSDT-EC part, Skylake and newer users can grab a pre-built here: [SSDT-USBX.aml](https://github.com/dortania/OpenCore-Post-Install/blob/master/extra-files/SSDT-USBX.aml)
|
|
* **IMEI SSDT**:
|
|
* If you have either a Sandy bridge CPU with 7 series motherboard or Ivy Bridge with 6 series motherboard, you'll need to either use the prebuilt or manually create it.
|
|
* **RTC0 RANGE SSDT**:
|
|
If you have X99 or X299, you'll need to configure it to your system
|
|
|
|
For users who don't have all the options available to them in SSDTTime, you can follow the "SSDTs: The long way" section. You can still use SSDTTime for SSDTs it does support.
|
|
|
|
## Running SSDTTime
|
|
|
|
Run the `SSDTTime.bat` file as Admin on the target machine and you should see something like this:
|
|
|
|
|
|
|
|
What are all these options?:
|
|
|
|
* `1. FixHPET - Patch out IRQ Conflicts`
|
|
* IRQ patching, mainly needed for X79, X99 and laptop users(use option `C` to omit conflicting legacy IRQs)
|
|
* `2. FakeEC - OS-aware Fake EC`
|
|
* This is the SSDT-EC, required for Catalina users
|
|
* `3. FakeEC Laptop - OS-aware Fake EC`
|
|
* This is the SSDT-EC, but the laptop version only Builds Fake EC and leaves the existing EC devices untouched, again required for Catalina users
|
|
* `4. PluginType - Sets plugin-type = 1 on First ProcessorObj`
|
|
* This is the SSDT-PLUG, for Intel only
|
|
* `5. PMC - Sets Power Management controller status`
|
|
* This is the SSDT-PMC, for Intel true 300+ series only, this device is missing from ACPI in recent boards and helps to bring back NVRAM support.
|
|
* `6. AWAC - Context-Aware AWAC Disable and RTC Fake`
|
|
* This is the SSDT-AWAC/RTC0, its purpose is to fix the system clocks found on newer hardware
|
|
* `7. USB Reset - Reset USB controllers to allow hardware mapping`
|
|
* This is SSDT-RHUB, used for resetting USB ports in macOS for Asus's Z490 motherboards
|
|
* `8. Dump DSDT - Automatically dump the system DSDT`
|
|
* Dumps your DSDT from your firmware
|
|
|
|
What we want to do is select option `8. Dump DSDT` first, then select the appropriate option(s) for your system.
|
|
|
|
> What about USBX?
|
|
|
|
For Skylake and newer plus AMD, you can grab a pre-built file here: [SSDT-USBX.aml](https://github.com/dortania/OpenCore-Post-Install/blob/master/extra-files/SSDT-USBX.aml). This file is plug and play and requires no device configuration, **do not use on Broadwell and older**.
|
|
|
|
**Troubleshooting note**: See [General Troubleshooting](https://dortania.github.io/OpenCore-Install-Guide/troubleshooting/troubleshooting.html) if you're having issues running SSDTTime
|
|
|
|
## Adding to OpenCore
|
|
|
|
Don't forget that SSDTs need to be added to OpenCore, reminder that .aml is complied, .dsl is code. **Add only the .aml file**:
|
|
|
|
* EFI/OC/ACPI
|
|
* config.plist -> ACPI -> Add
|
|
|
|
Reminder that Cmd/Ctrl+R with ProperTree pointed at your OC folder will add all your SSDTs, kexts and .efi drivers to the config for you. **Do not add your DSDT to OpenCore, its already in your firmware**. If you are unsure what this is referring to, go back to the OpenCore guide and select your config based of the architecture of your CPU.
|
|
|
|
For those who do not yet have a config.plist, you'll want to next head back to your respective OpenCore guides and create the config.plist:
|
|
|
|
* [OpenCore Install guide](https://dortania.github.io/OpenCore-Install-Guide/)
|
|
|
|
Users of `FixHPET` will also need to merge oc_patches.plist into their config.plist
|
|
|
|
Steps to do this:
|
|
|
|
* Open both files,
|
|
* Delete the `ACPI -> Patch` section from config.plist
|
|
* Copy the `ACPI -> Patch` section from patches.plist
|
|
* Paste into where old patches were in config.plist
