Installation
When installing VMware Workstation on Gentoo you need to download the bundle from VMware's website.

Required kernel options
To install and run VMware Workstation on Gentoo you need to enable these kernel options.

Kernel modules
VMware Workstation 16.0 is known to support up to linux 5.8, and 16.1 works on 5.10 from my testing. If you use an older version of Workstation it will require an older kernel, 15.5 supports up to 5.4, 14.1.7 suppots up to 4.18, and 12.5.9 supports up to 4.12. After a kernel upgrade you will have to rebuild the VMware modules. You can do this by running the following command.
