ARM Status

P/omap4: since a critical bug (lp963512 – “Latest kernel updates broke video on omap4″) was affecting 3.2.0-1410.13, for beta2 the kernel was reverted to a previous working version (3.2.0-1409.12). AFAIK the regression came with latest rebase on master (3.2.1[0-2]) while the TI BSP was unchanged – so it’s either a bad interaction between upstream/TI BSP or it’s a brand new bug we got from upstream.
lp956693 (“Broken perf with Ubuntu-3.2.0-1408.11 at Pandaboard”): one of the patch from Linaro tried to enable perf hw support but it wasn’t ready for prime, reverting it gave us perf ba
ck in a working shape.
lp666267(“Cross compiled headers package breaks DKMS compilation”): two patches that address this issue were resurrected from O and ported to P, scripts/* are correctly cross compiled no
w.

Milestone Targeted Work Items

apw, I assume you’ll get those cleaned up by Thurs. If not, I’ll do it.

   apw    hardware-p-kernel-boot    4 work items   
      hardware-p-kernel-config-review    1 work items   
      hardware-p-kernel-delta-review    3 work items   


Blueprint: hardware-p-kernel-power-management

Power management:

  • hdparm spin up/down measurements

  • Going to re-measure unity 2d vs 3d fairly soon.


Status: Precise Development Kernel

We are currently frozen for the upcoming Beta-2 release this Thurs, Mar
29. Only fixes critical for the release will warrent an upload at this
time. We just uploaded 3.2.0-23.33 which contains a critical fix for
bug 961482. We plan to upload all other queued patches immediately
following the release on Thurs. Note that Kernel Freeze is next Thurs
Apr 5. I intend to upload our final kernel no later than Tues Apr 3.


Status: CVE’s

Currently we have 71 CVEs on our radar, with no new CVEs added this week.
See the CVE matrix for the current list:

Status: Precise Development Kernel

We intend to uploaded the 3.2.0-19.31 kernel today. This upload
contains a rebase to v3.2.12, disables CONFIG_DRM_PSB_CDV, and provides
a necessary fix for pre-core99 UP machines which then allows us to
proceed with removing the non-smp PowerPC flavor. This will be the last
upload prior to Beta-2 Freeze this Thurs, March 22. Any uploads after
that are subject to approval of the release team. Beta-2 is next Thurs,
Mar 29.

Status: Precise Development Kernel

We uploaded the 3.2.0-18.29 kernel last Friday and we have just
rebased master-next to upstream stable v3.2.10 (minus 1 patch which
introduces a build failure). Beta-2 Freeze is next Thurs, March 22. I
plan to upload this Friday and hope that this will be the kernel we use
for Beta-2. Should any additional patches land which are deemed
necessary for Beta-2 we would have enough time to upload again no later
than Tues, March 20. Any uploads after that are subject to approval by
the release team.
Important upcoming dates:

  • Thurs Mar 22 – Beta-2 Freeze (~1 week)
  • Thurs Mar 29 – Beta-2 (~2 weeks)
