Release procedure

Here is a draft of a BIOS release procedure.

Stage one: EC:

  • Quanta e-mails EC release and changelog to the OLPC BIOS contact, signed and encrypted with PGP
    • see notes below
  • Quanta and OLPC test this version of EC

Stage two: Buildrom:

  • Pull EC release from http://dev.laptop.org/pub/ec/, check hashes
  • Update buildrom changelog and tag for release
  • Update SPI flash version string in buildrom binary
  • Create buildrom SRPM
  • Build two flavors of binary RPM for the two RAM variants

Stage three: Testing:

  • announce build to BIOS team and Ray, release candidate testing begins
  • test on a 256M board
  • install the binary RPMs on Tinderbox machines
  • >12 hours of burn-in warm reboot testing on Tinderbox
  • cold boot tests
    • we need a cold boot solution; X10 doesn't seem to like the power at OLPC
  • After automated tests, send "Who has tested?" mail asking for problem reports
  • Release after twelve hours if no problem reports

Stage four: Release:

  • Release builds kept in a separate directory
  • Update the version number in LB from release candidate to final
  • Announce new build and hashes to devel-boards@ (requires moderation).
