the Linux kernel hasn't widely made use of INVLPGB... In part because Intel engineers typically carry out much of the new x86 instruction optimizations within the Linux kernel and Intel processors do not currently support INVLPGB.

Sounds like AMD needs to fund more kernel development.

Without doing research, but the Linux Foundation is also the parent of the CNCF, the foundation that funds Kubernetes and many adjacent projects. I can imagine that they get a lot more money as there are probably more developers handling CNCF projects than the Linux Kernel.
