Unable to get XPS 15 2-in-1 9575 HD 630 work in 10.13.4

[jjzazuet]

Did you check in Windows to be certain the internal panel is actually connected to the IGPU?

For whatever it's worth, I've tried to replicate the configuration from @shiecldk and @honsontran. Key issues persisting:

1) No QE acceleration available for ig-platform-id 0x59B10000, can only boot using "-igfxvesa" option from Whatevergreen (screen remains active in text mode, stuck on "
IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0").
2) Keyboard is partially functional, track pad isn't (both keyboard and track pad stop working as soon as the track pad is touched).

Attached problem report files.

I do recall the laptop's display being connected to the HD 630 graphics device, but I'm sure the IOReg report will be more accurate. At this point, I'm pretty much also ready to give up.

Any feedback is appreciated. Thanks!

Try different ig-platform-id values.
And try injecting EDID.

The ioreg does show a display connected to IGPU.

According to the Whatevergreen Framebuffer patching guide (Post #2), these ig-platform-id values should correspond to different configurations of the HD 620 and HD 630 graphics devices. These are my boot results:

0x59120000 - black screen, no kp
0x59120003 - kernel panic
0x59160000 - stuck at gIOScreenLockState, no kp
0x59160009 - stuck at gIOScreenLockState, no kp
0x591B0006 - stuck at gIOScreenLockState, no kp
0x591B0000 - stuck at gIOScreenLockState, no kp

These boot attempts were performed with an EDID definition patched with the FixEDID app, injected through Cover (config.plist with injected EDID attached here).

The only promising ig-platform-id value appears to be 0x59120000 (similar to what @shiecldk and @honsontran found out) since it seems to be performing some sort of screen initialization, but then just staying stuck at a black screen (with the backlight still active).

The next option I think would be to try and disable Framebuffer ports 1 and 3 (2 is the port where the internal 4K panel is connected to). My hunch is still that this particular CPU + Vega GPU package must have a different port layout, making WhateverGreen behave differently. But it's just a hunch, so not worth much .

Any help or feedback is appreciated. Thanks.

For 4k you will likely need larger DVMT-prealloc than 32mb.
And your config.plist is not injecting EDID. The AAPL00,override-no-connect property is missing from config.plist/Devices/Properties/PciRoot(0)/Pci(2,0).

Just for reference I went through the entire BIOS extraction method described here to find out the possible options for setting DVMT pre-allocated value in the BIOS itself:

I can confirm that BIOS version 1.2 coincides with the findings of @shiecldk in post #1:

Since @shiecldk didn't appear to have issues in their BIOS by changing their variable variables via the UEFI shell, I'll try re-adjusting them, injecting the EDID and re-trying the boot sequence (with original BIOS rom images backed up just in case). Thanks!

I got Mojave 10.14.3 working on my XPS 9575. Attached is my EFI partition.

Works:
Display - only 7MB VRAM
Bluetooth
USB 3.1 & USB 3.0 - USB keyboard, Wifi adapter & external drives work

Does not work:
keyboard
trackpad
touchscreen

Hopefully this helps to move this endeavor to the next hurdle

Thanks for posting this!
I was able to boot to Mojave, i can confirm that your "Does not work" list accurate but i'd like to add that in Mojave the wireless card doesn't show, have yet to try it in Sierra. Also when i try editing the xconfig.plist file i get this:

Which is:
<dict>
<key>CustomUUID</key>
<string>CA581616-6C2D-4B07-B764-412008887872</string>
</dict>

Also in line 295:

<dict>
<key>Comment</key>
<string>AirPortBrcm4360 - fcvo</string>
<key>Disabled</key>
<false/>
<key>Find</key>
<data>gflSqgAAdSk=</data>

<string>AirPortBrcm4360</string>
<key>Replace</key>

</dict>
</dict>
</plist>


I'll be doing more test this weekend, again thank you this is the furthest ive gotten on this XPS 9575!

Glad that this is helpful.

My config.plist is messed up and Clover configurator could not read it anymore. I've been editing it using Textedit. My only aim now is to make that keyboard and trackpad work. I don't mind using USB for the rest, Wifi, Ethernet etc.

I use the USB hub below to connect to the Internet. It works beautifully. I also got another USB device for wifi if I wish to be more mobile.

gofanco SuperSpeed 3-Port USB 3.0 Hub and RJ45 Gigabit Ethernet 10/100/1000 Mbps with Type-C USB Adapter for Windows and Mac OS

Understood. I am using a thunderbolt hub with the same features and it works well. Got the audio to work but still no luck on the keyboard and trackpad...more to do.
