Clover Change Explanations

Rev 4222

It is my own wish

The task was follow.

My laptop Dell Latitude E6430 can be powered with Optimus enabled or disabled in BIOS. They are two different computers and I want to see in which mode I started before timeout is ended because sometimes it switched despite on my wish.

Now I wrote in config.plist

	<key>GUI</key>
	<dict>
		<key>ShowOptimus</key>
		<true/>

and see Clover GUI as

The criteria is a number of videocard found.

2 = Embedded Intel + Discrete == "~~Optimus~~" "Intel"

1 = Discrete only == "Discrete"

I am not sure if someone else needed this feature so default behaviour to be not show.

Rev 4223
It is accumulated update because I can't commit changes before.
update FakeSMC
move BrandString to be calculated before use
allow StrictHibernate when Fixup used
rename Optimus->Intel as it is more correct
block Dell specific SetVariable

In config.plist you may set

	<key>Boot</key>
	<dict>
		<key>HibernationFixup</key>
		<true/>

if you are using Lilu+HibernationFixup.kext

It will allow you to use mode 25.

EDITED. Don't bother!

It is calculated automatically.

Rev 4231

P-State generator in Clover will be compatible with some DSDT.

I found in my Dell E6430 follow line

       ^CPU0._PPC = Local0

But it was not possible with current clover generated SSDT because the _PPC was a method.

Now I make it to be the Name for CPU0 and link for others.

    Scope (\_PR.CPU0)
    {
        Name (_PPC, Zero)  // _PPC: Performance Present Capabilities
....

    Scope (\_PR.CPU1)
    {
        Method (_PPC, 0, NotSerialized)  // _PPC: Performance Present Capabilities
        {
            Return (\_PR.CPU0._PPC)
        }

and so on.

Rev 4233

Make menu for kext disabling inside Details menu to disable some kexts immediatly before OS started

See screens

enter menu

~~But if you enter Option before choosing an OS then you can see~~

Rev 4237

Kext disabling excluded from Option menu.

It will be only in Details menu

Zenith432 · October 15, 2017

Rev 4247

There was an oversight in handling hidden volumes. Volumes hidden with the GUI->HIDE mechanism in config.plist did not show up when pressing F3 to show them. This is fixed.

Slice · October 17, 2017

Rev 4248

Fix for undefined OS version in High Sierra installer. Explanation here

Slice · October 17, 2017

Rev 4249

Corrected two bugs.

1. Menu separation lines was clickable.

2. Entering kexts management menu may cause boot without kexts after return.

Both bugs corrected here, more tests needed.

Slice · October 17, 2017

Rev 4250

XCPM patch will no more be unconditional.

		<key>KernelXCPM</key>
		<true/>

Default value is .

It can arise some problems because old revision has default to true.

But many users can't boot at all because of this. Let it be conditional setting from config or from Clover GUI.

Rev 4272 - 4289

Accept updates by Rehabman

#2590

Slice · November 4, 2017

Rev 4268
correct MachineSignature before wake from hibernation.

It is attempt to cure an issue at some configurations that boot.efi failed to check

		//
		// check machine signature
		//
		UINT32 machineSignature			= 0;
		if(!EFI_ERROR(AcpiGetMachineSignature(&machineSignature)) && machineSignature != localHeader.MachineSignature)
			try_leave(NOTHING);

The patch will write the MachineSignature from hibernation image into FACS table. But it is wrong for good machines

Rev 4270

condition for signature fixup

Now this Signature Fixup will be conditional through config.plist

		<key>SignatureFixup</key>
		<false/>

Rev 4291

if not SignatureFixup, it will be zeroed.

Anyway, the Signature must be fixed

If true then the value is from hibernate image

if false then the value is zero and it will be copied by kernel into the image.

Rev 4293

Rev 4294

New Shell is able to correctly edit plists. Most important is config.plist. TAB characters converted to double spaces on the fly

Enter Shell

Shell> fs0:

fs0:> cd EFI\CLOVER

fs0:\EFI\CLOVER> edit config.plist

...

Press F2 to save the result

Press F3 to exit from editing

fs0:> exit

you will return to Clover

Enjoy!

Rev 4295
Show kexts versions in menu to disable them.

Rev 4296
A possibility to de-init Radeon cards.
It was very old problem since ElCapitan that AMD Radeon HD6xxx and up will not wake after sleep if used as first card.
If the card is secondary and CSM enabled then the card works fine. So the differences is initialisation.
The solution was found by vit9696 and used in private WhateverGreen.kext. Then Mieze proposed the solution as ACPI patch.
Now I included this into Clover.
You have to set in config.plist

	<key>Graphics</key>
	<dict>
		<key>RadeonDeInit</key>
		<true/>

Additional patches for EDID.

Now config.plist may contain follow EDID section

	<key>Graphics</key>
	<dict>
		<key>EDID</key>
		<dict>
			<key>#Custom</key>
			<data>AP///////wAGECGSAAAAAAASAQOAIRV4CunVmVlTjigmUFQAAAABAQEBAQEBAQEBAQEBAQEB3iGgcFCEHzAgIFYAS88QAAAY3iGgcFCEHzAgIFYAS88QAAAAAAAA/gBXNjU3RwAxNTRXUDEKAAAA/gAjMz1IZYSq/wIBCiAgAJo=</data>
			<key>#Inject</key>
			<true/>
			<key>#ProductID</key>
			<string>0x9221</string>
			<key>#VendorID</key>
			<string>0x1006</string>
			<key>#HorizontalSyncPulseWidth</key>
			<integer>100</integer>
			<key>#VideoInputSignal</key>
			<string>0xA5</string>
		</dict>
	</dict>

Custom is EDID obtained or created manually. You mostly don't need do it as Clover usually can obtain it by himself.

Inject=true informs Clover to inject Custom or Discovered EDID into video device properties. You have to set it to true is you do patches.

ProductID and VendorID - may be you want to mimic your display to be Apple manufactured. But you should know what you do. Making this patch I found that Brightness control stop working. Remove this patch and brightness control is working again!

HorizontalSyncPulseWidth - this patch helps to resolve garbled screen at boot with Intel graphics. Known problem of 8 apples.

I see that the patch is still needed

			<dict>
				<key>Comment</key>
				<string>Patch 8 apples</string>
				<key>Disabled</key>
				<false/>
				<key>Find</key>
				<data>AQAAdRc=</data>
				<key>MatchOS</key>
				<string>10.11</string>
				<key>Name</key>
				<string>IOGraphicsFamily</string>
				<key>Replace</key>
				<data>AQAA6xc=</data>
			</dict>

but this patch alone is not full solution. The apple is broken for a several seconds and then restored.

With new Clover setting HorizontalSyncPulseWidth = 100 there is a full solution. The image is good and not jumped.

VideoInputSignal - this is additional patch for the same problem but I found no inluence.

Definition of the value is follow

Bit 7=1

Digital input. If set, the following bit definitions apply:

Bits 6–4 Bit depth: 000=undefined, 001=6, 010=8, 011=10, 100=12, 101=14, 110=16 bits per color, 111=reserved Bits 3–0 Video interface: 0000=undefined, 0001=HDMIa, 0010=HDMIb, 0100=MDDI, 0101=DisplayPort

My default values for desktop 0x80 (Digital, all undefined), for laptop 0x90 -6bits per color?! - not good.

It seems value 0xA0 will be better if used.

And I don't know interface for intenal screen.

Credits. I was informed by Derek about this patch but initially it was wrong (byte 64 while it must be 63+65).

https://github.com/1and1get2/Clover/commit/ee301efdcce8ae1e47be21267490753a0c145c1d

The discussion was at tmx site as well wrong and without result. And I don't know who is initial inventor because in those matter it can't work properly.

Rev 4368, 4369

NVRAM and other runtime fixes for AptioFix.

Runtime code areas are no longer allowed to be relocated by boot.efi like runtime data areas. Runtime methods for NVRAM variables are shimmed to enable writing into runtime code regions during the methods, then disabled upon return. Native NVRAM should work for everyone now. AptioFix2 should be preferred over AptioFix, but you may need to calculate a slide value for now.

Slice · January 17, 2018

Rev 4378-4382

New set of memory fix drivers.

OsxAptioFixDrv and OsxAptioFix2Drv reverted to rev before 4368 so without NVRAM support. Let them stay here for history. And sometimes OsxAptioFixDrv is only working version for high warped memory map.

OsxAptioFix2Drv is a reduced version without relocation blocks and may not works on some hardware or with older OS version. But this version supported Hibernation while first one no.

OsxAptioFix3Drv is a OsxAptioFix2Drv rev 4369 renamed to be different. This version supported NVRAM. More runtime fixes in 4379. This version can be improved by clover crew in future.

AptioMemoryFix included in the package is third-party memory fix driver used as is. It is probably better then OsxAptioFix*. Choose it for a first attempt.

OsxLowMemFixDrv is also memory fix driver, not improved since rev608.

SIC! These 5 drivers should not be used simultaneously! Choose one of them!

Clover will be updated for mutually exclusion.

AptioInputFix is included in the package now. It is keyboard driver to support FileVault2 for those who have AMI UEFI BIOS.

The FIX is recommended to all users even if you are not going to fix DSDT.

Anyway the fix is safe.

Old setting inside DSDT fixes remains for backward compatibility but I recommend to exclude it from those section.
