You could make changes to installation ISO yourself, for testing.
Here are the instruction how to do this:
---
Download kernel-default*.rpm packages from the kernel of the day (KOT)
repository [1]
or build one yourself with additionally enabled modules.
Download latest "minimal" Tumbleweed ISO from here [2].
Specify which modules you think are essential for device to boot.
For example:
export MODULES="ufs-qcom ..."
Create driver upadate package (DUD) [3] from the downloaded/builded kernel
package:
mkdud --create qualcom.dud --dist TW --install repo kernel-default*
Rebuild installation ISO init ramfs [4] with your additional modules specified
above.
sudo mksusecd --verbose --create qualcom.iso --rebuild-initrd \
--initrd qualcom.dud --kernel kernel-default* \
--modules ${MODULES} --
openSUSE-Tumbleweed-NET-aarch64-Current.iso
Test new qualcom.iso. Please try to narrow down required modules. Once you
are happy with the result share the list of modules here.
Hope this helps.
