Hi, In the FESCO meeting today (http://meetbot.fedoraproject.org/fedora-meeting/2010-06-08/fesco.2010-06-08-19.30.log.txt), Fedora developers and some members of the OLPC community discussed the loss of Geode LX (i.e. XO-1) support in F13.
It looks like we are all in agreement that the loss of support was unintentional, but we postponed making a decision on the solution because we realise that we don't fully understand the issue. The only package we can see that uses nopl instructions is glibc -- why only glibc? What changed to make that happen? I've investigated and my explanation is here: https://bugzilla.redhat.com/show_bug.cgi?id=579838#c10 https://bugzilla.redhat.com/show_bug.cgi?id=579838#c11 In a nutshell: glibc now is more agressive than most packages with its optimizations, and takes an extra step to communicate the desired processor optimizations to the assembler. (CPU-specific optimizations in other packages are limited to the compiler and linker) What are the next steps? Do we take this back to FESCO? When is the next meeting? Thanks, Daniel _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
