SBUs are only a rough guide. They get less accurate when older toolchains are involved (e.g. if your host had an older gcc minor version than what was in the LFS version you built, your original SBU will be small because each new version of gcc takes longer to compile programs, so all your later LFS and BLFS SBUs will be bigger. Similarly, if you are building on an older version of LFS your BLFS SBUs will ofteny be quicker. In this particular case, I suspect Mesa might have been measured using LFS-7.0, not 7.1 (we don't normally update measurements when we update a BLFS checked/built tag, unless things are clearly wrong). Also, that measurement is presumably for the limited set of gallium drivers shown in the book's configure command. Those of us not using nvidia hardware will probably wish to enable other, or all, the gallium drivers (or omit nouveau). In my case I build all the drivers on my current hardware (I've got big disks now, I can afford the space and I'd like to know if any of them fail to build because of an update elsewhere) so my own figures will almost certainly not match what the book shows. ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
