== Minutes ==
 * Reviewed the agenda
 * Michael Hope is now the toolchain lead
 * Calls will be shifted to a public number starting next Monday
  * ACTION: Michael to organise and spread number.
 * Went over release dates
  * Loic suggested the second Tuesday of every month instead as it
gives the rest of working week to handle problems
  * Michael would like to keep close to the FeatureFreeze/FinalRelease
dates so that announcements coincide
  * ACTION: Michael to re-check dates and suggest something
 * The next release, due in a week, will be skipped due to no
significant changes since last release
  * ACTION: Michael to rename milestone
 * Hardware availability
  * CSL
   * i.mx51 in their data centre
   * Julian, Andrew: have IGEPv2
   * Yao, Chung-Lin: will get hardware
   * Loic pointed everyone to the internal hardware availability page
   * Ulric: is organising hardware
  * Loic wants to investigate using qemu as a buildd host
  * Michael will write-up and share his hardware.  Everything should
move into the data centre later
 * Benchmarks
  * Loic noted that we want everything in the open and reproducible,
so prefer freely usable benchmarks
  * Don't want trivial benchmarks
  * Most commercial benchmarks include the source but have
restrictions on sharing the results
  * Michael asked for suggestions on benchmarks
  * Michael to look at freely usable benchmarks such as lmbench
 * Current tickets
  * Yao and Michael will look at Firefox
  * Ulrich is investigating the next in the list
 * Michael would like to send a weekly 'State of the toolchain' update
  * Consumed by linaro-dev, Ubuntu toolchain maintainers, and perhaps
others like Ubuntu kernel maintainers
  * Loic suggested via Launchpad news
 * Discussed communication with Ubuntu
  * All notification to go via Ubuntu toolchain maintainers
  * U-T-M has responsibility to pass this downstream
 * Loic talked with a developer on Chrome OS
  * Interested in trying the toolchain
  * Currently plain GCC 4.4.1
  * Require something very stable
  * ACTION: Loic to find a name for the records
  * General want for us to try building Chrome OS using the Linaro toolchain
 * PowerPC
  * Ulrich talked with Matthias at the end of the sprint
  * From a Ubuntu perspective, don't want 4.5 to regress in features vs 4.4
  * Revert the 4.4 PowerPC changes, keep SH and MIPS.  Ubuntu doesn't
support SH or MIPS so no change
  * ACTION: Ulrich to confirm with Matthias

Next call is on Wednesday
