Dell Latitude 3330 Intel HD 4000 glitches/noise/artifacts

[jan4321]

Hi.
I am trying to run a Hackintosh on my Dell Latitude 3330.

I have followed this guide (UEFI, GPT/GUID):
http://www.tonymacx86.com/el-capita...de-booting-os-x-installer-laptops-clover.html
To make an installer with this config.plist:
https://github.com/RehabMan/OS-X-Clover-Laptop-Config/blob/master/config_HD4000_1366x768.plist
With the "Boot graphics glitch, 10.10.x/10.11.x" enabled.

I have successfully installed OSX 10.11.1.

However I am experiencing glitches/noise/artifacts on the laptop monitor. This noise to flickers when there is activity on the screen. When connecting an HDMI monitor this noise is not present on the HDMI monitor but still on the laptop monitor.

Here a picture that shows the noise (with screen mirroring on):


The problem is very similar to the problems experienced in this thread:
http://www.tonymacx86.com/el-capitan-laptop-support/176069-graphic-glitch-hd-4000-graphic.html

I have already tried to set ig-platform-id to other values as 0x01660003, but 0x01660003 is the only value that works.

There are no settings to change the DVMT preallocated memory size in the Dell UEFI. When checking the "Dedicated Video Memory" in Windows 10 it says 0mb, suggesting that DVMT is set to 32MB, not matching the 64MB for 0x01660003. However I have read that the Windows value is not reliable.

I am not sure what next steps to take to solve this problem. Please help, thank you.

You can always patch the framebuffer to match 32mb if you think that is how it is set.

Name: AppleIntelFramebuferCapri
Find: <0300 6601 0102 0402 0000 0004>
Replace: <0300 6601 0102 0402 0000 0002>

You should verify DVMT-prealloc by extracting BIOS/IFR and checking via UEFI shell though.

Enabling CSM (or legacy boot if CSM not available) may also help.

Ok, so I have implemented the above points:

I noticed however before applying the patch "[igpu] Rename GFX0 to IGPU" next to the GFX0 there are PCI0.VID references in the DSDT. Not sure about this.

Furthermore I checked the DVMT Pre-Allocated setting with help from this guide:
http://www.tonymacx86.com/yosemite-...hd-graphics-5500-os-x-yosemite-10-10-3-a.html

The value for 0x1C7 was set to 0x01, thus 32MB indeed. However changing this to 0x02 did not help.

The laptop monitor is still showing the noise, where can I go from here?

The value for 0x1C7 was set to 0x01, thus 32MB indeed. However changing this to 0x02 did not help.

The laptop monitor is still showing the noise, where can I go from here?

Did you verify that you successfully changed the setting to 64mb?

Did you enable CSM/legacy boot?

 

[jan4321]

Backlight control is not implemented.

I do not understand.
I have a working backlight control slider in system preferences. In the IOReq you can see AppleACPIPlatformExport/PCI0@0/AppleACPIPCI/IGPU@2/IntelBacklightHandler.
What is not implemented?

VID is part of the discrete GPU. Nothing to do with Intel graphics.

There is no other graphics card than the integrated Intel HD 4000. So can this be ignored?

Did you verify that you successfully changed the setting to 64mb?

Checking the 0x1C7 variable after changing and rebooting shows the variable is indeed changed. Not sure to how to verify that the DVMT pre-alloc is actually set to 64MB?

Did you enable CSM/legacy boot?

So I have this option in the BIOS settings:

Is this CSM? This has been on the whole time. The only other option is to ditch UEFI in favor of legacy/BIOS booting.
With legacy you mean old style BIOS booting? My Clover install is EUFI + GPT install, is switching to BIOS + GPT possible?

Of course.

Make sure there aren't two variables for the same...

Not quite sure what you mean by that.

Enabling CSM (or legacy boot if CSM not available) may also help.

So I created a Clover USB with legacy boot + MBR. Started my install with it, but the problem still persists.

Any other suggestions on investigating/tackling this problem?

Found a solution!

After stumbling upon this page:
https://discussions.apple.com/thread/6240037?start=0&tstart=0

In AppleIntelFramebufferCapri.kext

0035dc0:
0300 6601   0x01660003 
0102 0402   Ports/Pipes/NumFrameBuf
0000 0004   64MB - StolenMemorySize 
0000 0001   16MB - FramebufferMemory Size
0000 0060   1.5GB VRAM

(Notice the amount of VRAM has changed since the post mentioned above)

This finally made sense to me:

Name: AppleIntelFramebuferCapri
Find: <0300 6601 0102 0402 0000 0004>
Replace: <0300 6601 0102 0402 0000 0002>

However instead of changing the amount of stolen memory (DVMT prealloc) the framebuffer size was off for my machine.

Changing framebuffer size 16MB to 8MB fixed the noise!

Thus:

F: 0300 6601 0102 0402 0000 0004 0000 0001
R: 0300 6601 0102 0402 0000 0004 0000 8000

Added this to my Clover config.plist

No more noise!

Only now my hackintosh fails to boot with my patched DSDT. Not sure why... I will first try making a new one.

 

[RehabMan]

Not quite sure what you mean by that.

Check your IFR extract for multiple offsets for the same DVMT-prealloc setting.

So I created a Clover USB with legacy boot + MBR. Started my install with it, but the problem still persists.

Any other suggestions on investigating/tackling this problem?

No need to switch to legacy. But enabling CSM/legacy boot (still booting UEFI) can help.

You should try changing the "stolen size" to match your BIOS setting.
