Convert XOSI to GPI0 and RTC hacks OC format

[kecinzer]

Dear community,

I converted my laptop configuration from Clover to OpenCore and now I try to completely clean it to OC standards. Only 2 things left.

 

1) RTC hack

Currently I’m using this ACPI rename, that causes shortening of RTC device length to 0x02 (normally it’s 0x08). Without this hack, every time I restart laptop, I see BIOS POST about real time clock changes.

 

<dict>
				<key>Comment</key>
				<string>RTC fix</string>
				<key>Count</key>
				<integer>0</integer>
				<key>Enabled</key>
				<true/>
				<key>Find</key>
				<data>
				RwFwAHAAAQg=
				</data>
				<key>Limit</key>
				<integer>0</integer>
				<key>Mask</key>
				<data>
				</data>
				<key>OemTableId</key>
				<data>
				</data>
				<key>Replace</key>
				<data>
				RwFwAHAAAQI=
				</data>
				<key>ReplaceMask</key>
				<data>
				</data>
				<key>Skip</key>
				<integer>0</integer>
				<key>TableLength</key>
				<integer>0</integer>
				<key>TableSignature</key>
				<data>
				</data>
			</dict>

 

I would like to convert it to new Open Core rtc-blacklist variable.

 

2) Touchpad I2C GPI0 hack

Currently I’m using _OSI to XOSI rename and „Windows“ hack, that works ok, but I red on Dortania guide (https://dortania.github.io/Getting-Started-With-ACPI/Laptops/trackpad-methods/manual.html) that GPI0 method is better.

 

On my DSDT I get variables and prepare my SSDT, but touchpad not working.

 

DefinitionBlock ("", "SSDT", 2, "hack", "I2C", 0x00000000)
{
External (GPEN, FieldUnitObj)
External (SBRG, FieldUnitObj)

Scope (\)
{
    If (_OSI ("Darwin"))
    {
        GPEN = One
        SBRG = One
    }
}
}

 

Can someone please help me little bit?

I'm not laptop user, but shouldn't there be in GPI0 _STA or _INI? It's a guess, but might work.

DefinitionBlock ("", "SSDT", 2, "hack", "I2C", 0x00000000)
{
    External (_SB_.PCI0.GPI0, DeviceObj)
    External (GPEN, FieldUnitObj)
    External (SBRG, FieldUnitObj)

    Scope (_SB.PCI0.GPI0)
    {
        Method (_INI, 0, NotSerialized)  // _INI: Initialize
        {
            If (_OSI ("Darwin"))
            {
                GPEN = One
                SBRG = One
            }
        }
    }
}

Try also with Scope (\).

No, it not working.

I'm using variable preset method, so I don't need define method. And it's in _STA method.
