I have snatched victory from the jaws of defeat.
Tangent
All I had to do to get vmware-workstation16 working was to add the linux6_15.patch to the sources array in the PKGBUILD and add the patch line from vmware-workstation’s PKGBUILD so that patch applies. Now I have vmware-workstation16 working on Linux 6.15! I may add this patch as a diff file in the AUR comments, lol.
Now for 17.0.2, I also got that working (it’s funny that it works as soon I ask on the forum, lol. Turns out that the same patches in my other vmware thread still work when I use linux6_15.patch, and as a result you’ll find this package on the AUR sooner rather than later, as vmware-workstation-noxsave.
It’s funny how sometimes right after (or a bit after) making a help post, you get the answer by yourself (lol).
TL;DR: I fixed vmware-workstation16 (AUR package) by adopting the package (lol) and pushing my changes, and fixed 17.0.2 by creating vmware-workstation-noxsave on the AUR.
