These HALs are proprietary and binary-only. However, the open-source project (and later) has reimplemented some HALs for Exynos 7885 using reverse-engineering. The LineageOS community often uses a mix: stock vendor blobs + minimal open-source shims.

The software ecosystem of the Exynos 7885 consists of several distinct proprietary and open-source drivers: 1. GPU Drivers (ARM Mali-G71 MP2) exynos 7885 driver

If your Windows PC does not recognize your Galaxy A7 or Tab A, you need the official Samsung USB Driver. These HALs are proprietary and binary-only
LTE Cat.12 3CA (600 Mbps download) and Cat.13 2CA (150 Mbps upload).
For developers and enthusiasts, "mainlining" means porting the Exynos 7885 source code to the upstream, modern Linux kernel (e.g., Kernel 6.x). This frees the device from old Android software limitations and allows it to run pure Linux distributions like Ubuntu Touch, PostmarketOS, or Arch Linux ARM.

Search for your specific device model (e.g., SM-A850F for the Galaxy A8). Download the kernel source code zip file.
