It is known that Xiaomi shipped their kernel without WIFI and AUDIO drivers. These drivers can be acquired from Codelinaro git repository.
These drivers are built-in inside the kernel, and they are updated with latest changes from QUALCOMM for maximum PERFORMANCE and STABILITY
RMNET performance drivers are included too, which optimize and improve mobile data speed drastically.
You need to know your current kernel Qualcomm TAG, you can find it in OEM github by checking commit history. After you know the base tag, you can then upstream to newer version.

You can also build these drivers as modules, but it is hard to add them to vendor partition on MIUI system because these partitions are read-only, and cannot be edited except by editing whole super partition.
On AOSP, this is not the case, so you can remount read-write the vendor partition, and add module .ko files to /vendor/lib/modules.
After building the kernel, run make INSTALL_MOD_STRIP=1 modules_install. You can then find the module files in vX.XX.XXX folder, this folder name is the same as the kernel version.
