Re: Microcode to disable TSX

This Update didnt help me.

I think there is to reasons:

1) Intel didnt fix TSX-NI in there products.

2) All modern Linux kernels use kernel otion - microcode early update that overwriting CPU microcode

Can Intel update microcode.dat file with fixed TSX-NI. To Linux kernel-firmware workin right?
