Blueprint: hardware-p-kernel-power-management

Power Management:

  • Write up results from wake events analysis and file lots of bugs

    http://zinc.canonical.com/~cking/power-benchmarking/events/

  • Write cpustat: git://kernel.ubuntu.com/cking/cpustat.git
    Test CPU utilization, results:

    http://zinc.canonical.com/~cking/power-benchmarking/cpu/

  • Investigate MSR_IA32_ENERGY_PERF_BIAS on sandybridge, no +ve results
    need to rig up Ivybridge desktop to sanity check this.
  • LP#911325 – new pm-utils scripts to save power
  • Collect power measurements on Hardy, Lucid, Maverick, Natty, Oneiric, Precise


Status: Precise Development Kernel

Over the holiday break we rebased to v3.2-rc7 and uploaded. Aside from that not much else has been done.
Important Upcoming Dates:

  • Thurs Feb 2 – Alpha 2 (~4 weeks)


Status: CVE’s

Status: Stable, Security, and Bugfix Kernel Updates – Oneiric/Natty/Maverick/Lucid/Hardy

Here is the status for the main kernels, until today (19/12):

  • Hardy – 2.6.24-30.98

    • New kernel, now in verification. Contains commits for 5 CVEs.

  • Lucid – 2.6.32-38.82

    • New kernel, waiting to be copied to -proposed. Contains a stable upstream
      release as well as some CVEs. This also turns CONFIG_NET_NS back on.

  • Maverick – 2.6.35-32.64

    • New kernel, waiting to be copied to -proposed. Contains a rare, stable
      upstream release as well as some CVEs.

  • Natty – 2.6.38-13.53

    • New kernel, now being built.

  • Oneiric – 3.0.0-15.25

    • New kernel, now in verification. A regression was identified in the
      previous -proposed kernel (bug 904569). The offending commit was reverted
  • Launchpad bug 904569 in linux (Ubuntu Oneiric) “Linux 3.0.0-15 causes laptops to fail to resume from suspend (Dell XPS 1645, Sony Vaio VPCF1390)” [Undecided,In progress]
    and this kernel produced.
