Testing of as yet untested functionality [Thunderbolt 3, DRM]

[EETagent]

I need help testing the following functionality

• FireVault 2
• Power Management Tested. Works
• Thunderbolt
• USB Type C Video output Tested. Works
• Upper (TB3 & charging) USB Type C port Tested. Works
• DRM - FairPlay and Widevine
• Wireless Sidecar ( With supported Broadcom card ) Tested. Works

"- [ ] Sidecar with 14,1 SMBIOS Not really needed, but would like to hear if someone managed to get it working "

Additional reports about sleep functionality and PM981 would be appreciated.

Power Management
I had to replace CPUFriend and CPUFriendDataProvider Kexts with my own. However, my T480 has an 8350u.

The item that really made a difference was undervolting with Voltage Shift. Unfortunately, it will vary from CPU to CPU, but I've gotten stability at -110 for CPU and Cache, and -70 for GPU. I set both power limits quite high at 60w; however, this is the piece I'm most unsure about. Also, after sleep, I lose the undervolt. It is supposed to check every 5 minutes to make sure, but I don't think that piece is working correctly - still looking into that. However, undervolting in a pretty cool room increased my Cinebench R20 score from 1529 to 1735.

A third piece of power management is actually hardware related. I installed a 01YR202 heatsink made for the dGPU model, making sure to cover the dGPU interface with Kapton tape. Besides the tape, it's a plug and play solution - just add thermal paste. There are even screws on our motherboard for the GPU portion. I only saw minimal benefit, so it might not be worth the price and effort.

-110 is stable value for me too. GPU for me could be undervolted up to -80 but I didn't test long time stability. I know about VoltageShift, problem is that kext and script have to be in same folder and I would like to move VoltageShift.kext to EFI instead of disabling SIP for kexts. There are some people over internet which have VoltageShift in EFI folder so it should be possible, I would probably ask on Reddit about this.

@danny7g Can you please test these two files. It is a modified version of voltageshift program which should work with kext in EFI folder. I think it works, but it could be a placebo effect.

Or the new EFI in the testing branch

[danny7g]

Thanks!

Voltageshift worked in the EFI folder. I reconfigured with my undervolt numbers. I tested by setting the folder in terminal "cd /Volumes/MAC\ EFI/EFI/OC/Kexts" and running "./voltageshift info" before and after sleep. I also downloaded the original script and tested outside of the kexts. I then removed the script from the Kexts folder. Finally, I tested in Cinebench to confirm that the undervolt was working before and after sleep, just in case the Voltageshift info command didn't work the way I was thinking. Everything looks good.

I haven't tested the GPU stability with the undervolt again yet, but previously I used Unigine Heaven. With all of the tweaks, I was getting higher Cinebench scores than stock for a 8350u. For Unigine Heaven, the UHD 620 GPU has been under-performing stock even though hardware acceleration is working for me (tested with VideoProc). The only thing that made a slight improvement was switching the RAM dedicated to graphics to 2 GB; this is already built into your config.plist.

I'm using a modified version of the testing branch EFI folder now. I don't need some items like light sensor, never got IO sensors working (I may return to that because I want to control fan speeds), added Broadcom Bluetooth/Wifi, I'm not sure if NVME Fixup is relevant, may remove SSDT-HRTF in future testing, etc. I'm still getting some junk in the Verbose boot log, but still need to play around with it some more. Once upon waking from sleep I lost touchpad functionality, but I can't recreate the issue.

Attached is my current version of the testing EFI with platform info removed from the Generic section of the config.plist.

Thanks for your feedback.

I am not sure if I understand correctly what you did with the VoltageShift as there is no need to have EFI folder mounted. Original voltageshift wouldn't work as there is part which checks if the VoltageShift.kext is in the same folder.

if u came this far, u can change the following file, change the ```unloadkext()``` and ```loadkext()``` function to do nothing, compile the kext in xcode then should be good, after this u can load it in efi

https://github.com/sicreative/VoltageShift/blob/master/VoltageShiftAnVMSR/main.mm

Good point about the light sensor kext, will remove it too. It's useless. I'm not sure though about SMCSuperIO as macOS could use it for fan control.

There are currently ( at least for me ) issues with VoodooRMI ver. 0.3.0. TrackPad/TrackPoint sometimes don't work. You can for now revert to version 0.2.0

[danny7g]

the command "./voltageshift info" is querying the system status, not the kext itself.

when i had the kext load from outside the EFI, i would get a return value of -110 CPU -70 GPU -110 CPU cache. however, the values would go to zero after sleep. now that it is loading from the efi, after sleep my values are still -110 -70 -110.

I can confirm that undervolting works, but somehow I can't achieve the same undervolting and temperatures that I can achive under windows 10. Under Windows 10 I can undervolt to -120 CPU -80 GPU -120 Cache while under macOS 15.5.5 I can only undervolt to -115 CPU -80 GPU -115 Cache (isn't a big difference). Also while I can get ~35º C at idle on Windows 10 I'm getting ~40º C on macOS. I tried to create my own CPU Friend profile, but I'm not pretty sure about how good or bad it currently is (I'm still learning about Hackintosh). My CPU is i7-8650u. Do I have to modify any other file to match the config to my CPU?.

I can help with other functionality tests that doesn't involve thunderbolt or USB C video output, just tell me what do you want me to do. I can also confirm that PM981 doens't work at all. I achieved to somehow install mac OS but it stopped working after two or three boot attempts. Then I decided to switch to SM961 (I read that it was compatible) but I'm getting the problem described on the issue I reported. Other than that I can confirm that sleep works without any conflict and that both the lid's led and the power button led starts to blink after 10-15 seconds. I can try to messure how long does it take to start to blink. I didn't find any trouble waiking up from sleep. Also I will try to messure power consumption on sleep state.

Finally, I can confirm that NVMeFix works to improve SSD temperature. My temperatures reduced ~10º C (from 43º to 33º) using it.

I can confirm that sleep works pretty well. Left my thinkpad sleeping all night (from 12:00AM to 8:15AM) and it only consumed 1% of battery. Here's my energy saver config:

[zombillano]

I tried to make SMBus work without any success... Is there a way to control fan's RPM? Also I found that battery info. isn't that accurate. Cycle count doesn't match as well as full charge capacity (at least with what lenovo vantage shows).

TrackPad and TrackPoint does not work for you?

Is there a way to control fan's RPM?

I think this should be doable with some Fan control utility which does not depends on fan placement by SMBIOS.

Also I found that battery info. isn't that accurate. Cycle count doesn't match as well as full charge capacity (at least with what lenovo vantage shows).

I think that battery health info is unimportant for Hackintosh. If actual battery life indicator works, it's fine.

I confirm Sidecar working on my T480 (Fenvi BCM94360NG). I removed all the intel wireless kexts.

Wired, wireless? If you mean wired, can you test wireless connection too please. It should work with supported Broadcom card

[tienhuynh5312]

It is wireless card. It performs good and no lag.

Perfect. I could have deduced that.
