0a896953 - arm-3.0-wip-wfi

  • olpc-ec: consolidate code and ensure TxFIFO is empty before writing to it
  • EC logged in S7, runin 0.17.0 or 0.16.7 (not C2 builds) if possible
  • Past kernels tested briefly in the past ~12 hours suggest that the fixes in said kernels may fix all known easily reproducible hangs. Need to prove/disprove this.
  • If you have enough systems, try using stock runin 0.17.0-style settings as well as anything known to cause particular types of failures. (EC failures seem to be common within a few hours with 10s on/10s off suspend, only using runin-main/gtk/common/tests/sus/battery.)
  • testing by
    • James Cameron, six units, defconfig, runin 0.17.0, 10sec/10sec, 60sec watchdog, 0 to pm_async, started around Sat Jan 7 08:24:00 UTC 2012,
      • one C1 SKU201 hang during resume, see host log,
      • one B1 hang with SET_BLOCK_COUNT, see host log,
      • one B1 hang with SET_BLOCK_COUNT, see host log,
    • Samuel Greenfeld, five C1 units, runin 0.16.7 setup like 0.17 (light sensor test disabled), 0 to pm_async
      • one C1 SKU201 hang during resume, normal runin settings, see [host log]
      • B1 testing being setup to try and reproduce SET_BLOCK_COUNT hangs above

  • http://dev.laptop.org/git/olpc-kernel/commit/?h=arm-3.0-wip-wfi&id=196c2f80
  • testing by
    • James Cameron, with a local debugging patch, saw two instances of eMMC "error -110 sending SET_BLOCK_COUNT command", on C1 SKU201 and C1 SKU202, two test units with full runin 0sec/3sec (extreme) suspend and resume failed to show any hangs, currently going are five test units with full runin 10sec/10sec (aggressive) suspend and resume.
      • C1 SKU202 reported EC related kernel problems, see log, should be fixed in later kernels.

46e079fe - arm-3.0-wip-wfi

  • http://dev.laptop.org/git/olpc-kernel/commit/?h=arm-3.0-wip-wfi&id=46e079fe
  • EC logged in S7
  • Should fix the hang caused by suspend being aborted due to a wakeup event. May also help with other IRQ hangs as I have fixed a previous mistake I made when moving the audio island code.
  • Testing aborted suspends can be done by running this command and then hitting the keyboard right away.

echo $(cat /sys/power/wakeup_count) > /sys/power/wakeup_count && echo mem > /sys/power/state

  • testing by
    • James Cameron, with a local debugging patch, saw one instance of eMMC "error -110 sending SET_BLOCK_COUNT command", on C1 SKU201, see log tail, and several instances of the hang in dpm_resume().
