[REQUEST] add support for Lenovo Z5 Pro GT (lenovo-heart)

Hi. Some resources before I explain the situation: LineageOS kernel source tree: https://github.com/LineageOS/android_kernel_lenovo_sm8150/ deviceinfo dump of working device-lenovo-heart:

What i did manage to do is this:

1. Clone whole LineageOS tree, do repo sync, set up everything for lenovo heart, with proprietary blobs set up.
2. Modify kernel config to be more postmarketOS friendly.
3. Compile kernel + dtbo image
4. Thru some scripting, extract revelant parts of kernel into linux-lenovo-heart/, set up device-lenovo-heart, APKBUILDs and other files.

I cannot for the life of me make the kernel compile via standard postmarketos environment without a slew of issues. LineageOS toolset built kernel: the device does boot, i am able to ssh into it via usb.

I really tried to make it work and tried from various angles. I tried modifying qcacld3 driver in that tree to fake into using non-android firmware loading, construct wlan max into bin file, various places for firmware placement,wlan is in limbo: doas (lukas@lenovo-heart) password: [ 0.000000] OF: reserved mem: initialized node pil_wlan_fw_region, compatible id removed-dma-pool [ 1.405837] iommu: Adding device soc:ipa_smmu_wlan to group 4 [ 3.121672] wlan_hdd_state wlan major(493) initialized lenovo-heart:~$

I have the device and it is unlocked, but screen is not working. I wanted to make it into headless server that would run docker containers. Unfortunately, I'm stuck.

I'm not sure if I am asking for too much, but I would love to make it work somehow. Preferrably, via this kernel tree.

Are you open to requests to support more devices?

I could definitely help, give feedback of what works for it, even if its quite limited because of cracked screen.
