According to the list: 124223 it is currently not officially supported. I have been running Fedora Workstation 42 for quite some time and I have had no major problems from the Parallels Tools updating and working just fine.
Same here. Compilation of module `prl_fs_freeze` fails with "objtool: init_module is deprecated use module_init(fn) instead" -- happens with kernel 6.15 onwards. In ArchLinux the same issue has already been solved with VMware drivers: https://aur.archlinux.org/cgit/aur.git/tree/vmnet.patch?h=vmware-workstation. Applying the modifications in the source code of the prl_fs_freeze module helped.
Btw Parallels uses `cc` instead of `gcc` - this leads to 'kernel module tainted' notifications - Parallels does not correctly identify the compiler used to compile the sources of the kernel. Changed it hard in Makefile.kmods to use gcc.
