hehehe Thanks, Petkov!
Instead distros, I was thinking in HPC vendors, (SGI, etc), where those can ship an optmized kernel compiled to the target CPU inside the HPC equipment, resulting in a better product. Well, I've reading a HPC equipment vendor documentation explaining that warrant will be lost if user compile&install a new kernel for that equipment. So, make sense the HPC vendor ships a optimized kernel for target HPC customer. About the proof, HPC vendors would give us an answer. :) 2016-12-19 15:31 GMT-02:00 Borislav Petkov <[email protected]>: > On Mon, Dec 19, 2016 at 03:09:50PM -0200, Gustavo da Silva wrote: >> Good afternon! >> >> Are there reasons to 'Kconfig.cpu' and 'Makefile' not contains the >> 'gcc -mtune=???' >> recent options? > > This keeps popping up every couple of months.
