# 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 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?:
|
|
|
|
* **HEDT SSDTs**:
|
|
* The ACPI is odd on these platforms so manual work is required
|
|
* This includes X79, X99 and X299 systems
|
|
* **Laptop EC fix**:
|
|
* This is because you need to use an ACPI rename over an SSDT on laptops
|
|
* **SSDT-PNLF**:
|
|
* Need to be configured to your system
|
|
* **SSDT-GPI0**:
|
|
* Need to be configured to your system
|
|
* **AWAC and RTC0 SSDTs**:
|
|
* 300 series intel boards will also need to figure his out(Z390 systems are most common for requiring this but some Gigabyte Z370 do as well)
|
|
* **PMC SSDT**:
|
|
* For fixing 300 series intel NVRAM
|
|
* **USBX SSDT**:
|
|
* This is included on sample SSDTs but SSDTTime only makes the SSDT-EC part, Skylake and newer users can grab a prebuilt here: [SSDT-USBX.aml](https://github.com/dortania/Opencore-Desktop-Guide/blob//master/extra-files/SSDT-USBX.aml)
|
|
|
|
For users who don't have all the options avaible to them in SSDTTime, you can follow the "SSDTs: The long way" section. You can still use SSDTTime for SSDTs it support for you.
|
|
|
|
## 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
|
|
* `2. FakeEC - OS-aware Fake EC`
|
|
* This is the SSDT-EC, required for Catalina users
|
|
* `3. PluginType - Sets plugin-type = 1 on CPU0/PR00`
|
|
* This is the SSDT-PLUG, for Intel only
|
|
* `4. Dump DSDT - Automatically dump the system DSDT`
|
|
* Dumps your DSDT from your firmware
|
|
|
|
|
|
What we want to do is select option `4. 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 prebuilt file here: [SSDT-USBX.aml](https://github.com/dortania/Opencore-Desktop-Guide/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://desktop.dortania.ml/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/Crtl+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.
|
|
|
|
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
