Bluetooth is still an issue I see, sorry. Still my xps 9360 does recognize BT I have the
Broadcom BCM94352Z
Please try this. Put you laptop at sleep. Then disconnect AC Power. Wake up you laptop and tell me which is the BT device name. See what I wrote some posts above :)

Thank you

Is it possible to modify the VoodooPS2Controller? @RehabMan
Full source code is available on my github, if you'd like to tweak it.
Also, there are many settings in the Info.plist files all of which can be overridden with ACPI.

Note: Your real goal should be to get an I2C-based driver working for the trackpad (PS2 does not have the bandwidth for good trackpad response).

So i connected my XPS to my iPhone X it connects. And when I return in HS from sleep BT is still available.

I don't have bluetooth headphones, so can't test audio.

I see, do you have any experience with http://forum.osxlatitude.com/index.php?/topic/1948-elan-focaltech-and-synaptics-smart-touchpad-driver-mac-os-x/ aka ApplePS2Smarttouchpad? I notice some improvements instead of VoodooPS2Controller or is it just me?

Has anyone tinkered with this? Worth a try, if you have time (I unfortunately do not).

Already tried and tested, even found the right pin value, but I have no experience nor nowledge in DSDT editing, only patching following explicit guides here and on some other forums. So I failed to get it working, but the trackpad is recognized in ioreg, and be ready to use an external usb mouse during testing, as you'll have no mouse input once i2c kext loaded.

And device name remains BCM94352Z after you return from sleep while on battery?

Does anyone know if there are any IFR variables to change when the fans kick in or allow OS level fan control? I went through the IFR.txt and couldn't find anything that clear.

edit: i've extracted the ROM and IFR from the 2.5.1 firmware on the XPS13 i5 8520u

It confirms the following variables are the same from 2.2.1

Intel(R) SpeedStep(tm)
2.3.1: 0x4AB --> 1 (Enabled, Default: Enabled)

Intel(R) Speed Shift Technology
2.3.1: 0x4AD --> 1 (Enabled, Default: Disabled)

CFG Lock
2.3.1: 0x4DE --> 0 (Disabled, Default: Enabled)

DVMT Pre-Allocated
2.3.1: 0x785 --> 0x6 (192MB, Default: 32MB)

DVMT Total Gfx Mem
2.3.1: 0x786 --> 0x03 (MAX, Default: 128MB)


----------------
Thunderbolt(TM) Support
2.3.1: 0x443 --> 1 (Enabled, Default: Enabled)

Thunderbolt(TM) PCIe Support
2.3.1: 0x44A --> 1 (Enabled, Default: Disabled)

Thunderbolt Usb Support
2.3.1: 0x44C --> 1 (Enabled, Default: Disabled)

Windows 10 Thunderbolt support
2.3.1: 0x13C5 --> 1 (Enabled, Default: Disabled)

This is all I can find in relation to fan control in the IFR file

curiously checking if FAN2 is enabled in uefi shell shows it is despite the xps13 having a single fan

If i check the
Fan Control Override, Variable: 0x10C9
it reports as 0x00, is it too risky to try changing it? I have several of these laptops and to be honest im open to bricking one

Update

So I was messing with some IFR variables, I managed to brick the bios.

Recovery was interesting, I made a FAT (not fat32) drive with the 2.5.1 exe, the 2.1.0 bios exe renamed BIOS_IMG.rcv as well as the setup rom file from 2.2.1.


following the standard procedure, unplug batt- cmos batt- hold power to clear nvram- replug - plug in usb then hold escape/ctrl and plug AC did not work.

However on second attempt I placed placed the flash drive in (left plug) BEFORE reconnecting the battery (i connected rtc battery first followed by main battery)

As soon as the battery connector went in it booted right up to an error about defaulting BIOS. (no keys pressed or held, no AC plugged in)

I attempted to flash bios from the F12 boot menu, however it did not work with the slightly unbricked bios.

Then I powered off, held escape/control, plugged in power cable (with usb in left slot) and loaded the BIOS recovery mode.

This allowed me to downgrade all the way back to the factory shipped 2.1.0 from 2.5.1

One tidbit which may or may not mattered was the battery connector only went in about half way the second time, so when it finally booted the front LED was flashing orange/white, and the laptop did not recognize the battery (even though it booted without power plug) so it refused to do a BIOS recovery, I shut down pushed the battery connector in the rest of the way and rebooted into BIOS recovery.

Perhaps the battery giving power but not info was what jogged it to boot. Regardless it took a good hour of mucking about to get it to boot.

To be clear I had 3 bios revisions on the recovery drive, stock 2.5.1.exe, the 2.1.0 exe renamed BIOS_IMG.rcv and the 2.2.1 ROM file. BIOS recovery console did not let me select a file, it chose 2.1.0 which means the proper fix must entail having the BIOS executable renamed to BIOS_IMG.rcv for the ctrl/esc recovery to work. It may also allow others to downgrade.

Im now going to update to 2.2.1 (same bios as my other device I dont want to brick) and start playing with IFR again.

Any input would be appreciated

I plan to change the cpu and gpu undervolt to 0x4B (-.075v) do you think this is unsafe? Should I test with XTU in windows first?

What is the purpose of the thunderbolt variables?
Thunderbolt(TM) Support
2.3.1: 0x443 --> 1 (Enabled, Default: Enabled)

Thunderbolt(TM) PCIe Support
2.3.1: 0x44A --> 1 (Enabled, Default: Disabled)

Thunderbolt Usb Support
2.3.1: 0x44C --> 1 (Enabled, Default: Disabled)

Windows 10 Thunderbolt support
2.3.1: 0x13C5 --> 1 (Enabled, Default: Disabled)

Will they have any effect in OSX? I'm not sure if it was those or changing the active trip point temperatures that bricked it last time.

I want to test the active trip point temps again. They should just change when the fan kicks in, 71 degrees is too hot for fan response.
The default variable for active trip point 1 is 71 degrees Celsius, but according to intel power gadget, its not until nearly 90 degrees that the fan really kicks in. The ifr text points show it can be set it much lower. If it would start cranking when the bottom gets hot (~55degrees) the hardware will live longer (my end goal)

I also saw the XMP variables in the IFR. Should they be left untouched?

Once again I'm prepared to brick one of my machines but obviously I am not trying to.
