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.

especially considering how they went into the server market again; like what, are they expecting people to shove a 256 thread processor into a windows server?
