[Guide] Using Clover to "hotpatch" ACPI

[gujiangjiang]

You need to use 'External' to access the fields present in DSDT from the SSDT.

I found it only with EC0 in DSDT and i have add it in the SSDT but still have mistake.

No idea without details.
Suggest you read the ACPI spec and ASL language reference so you know what you're doing...

Thanks very much,it is actually lost "External"

I will try this SSDT and DSDT patch later.

Another question is how to make this DSDT patch with "(".it cause error.

Any method that is calling B1B2 needs to use the rename/replace pattern.

I understood correctly, this method and implement it?
I realized it right?

Can I remove these devices from their DSDT (LNxx)?

No idea what you're asking.

I test the hotpatch way and it's very nice.

Except WiFi (AR9285), and brightness control (only via Home/Pause button and PgUp ScrLk)via native keys.
Didn't test sleep yet.

Look my outputs.

Brigthness control keys are usually done by patching the appropriate _Qxx methods.
Use Rename/Replace pattern.
AR9285 WiFi does not require ACPI patching. Use ProBookAtheros.kext as per FAQ.
