  • Release is looking good
  • Talked with Michael re: what we're doing with KVM
  • Talked with Dave Pigott re: Fast Models in the lab

Ken:

  • Proceeding with Openembedded
  • init was failing as they're linked against glibc and against the loader which is ARMv7
  • Which causes an illegal instruction
  • Re-built minimal image using ARMv7 with vexpress defconfig
  • Boots fine!
  • Moving onto the SATO image to get more packages
  • GTK+ is failing with libstdc++ stuff, still investigating

  • Upstream has made a specific suggestion including patch covering proper abstraction
  • Merging upstream ideas with Ulrich's WIP
  • Looking pretty good
  • Moving over to the GCC side
  • Did a priority order including Richard's and others WIP patches
  • Prepared for backporting one of bero's bugs
