Hello!
Please see below for my rough notes from the kernel consolidation,
and please reply to the group with any errors or omissions.
Thanx, Paul

Attendees: Arnd Bergmann, Dave Martin, Jeremy Kerr, John Stultz,
Mounir Bsaibes, Nat Waddell, Nicolas Pitre, Steve Sakoman,
Paul E. McKenney.
o Kernel Consolidation -> Kernel. Job 1 will of course continue
to be kernel consolidation, but will continue to take on other
kernel work.
o Kernel requirements
(https://wiki.linaro.org/Internal/TSC/MinutesToBeAgreed)
o Virtualization requirements
(https://wiki.linaro.org/Internal/TSC/MinutesToBeAgreed)
Arnd Bergmann, Dave Martin. Discussion of implementation
strategy -- full virtualization vs. paravirtualization.
TrustZone.
o Requirements schedule
o Requirements discussion, mostly in TSC.
o Discussion and refinement at Orlando.
o Blueprint generation in the 2-3 weeks following Orlando.
o Round table:
o Arnd Bergmann: BKL work mostly submitted. Looking into
I/O spaces and SoCs -- address-space annotation.
o Dave Martin: One perftools patch to be pushed to mainline.
John Rigby working on build of perftools.
o Jason Hui: iMX51 work on device trees. Need assignment.
Reviewed BSP review, need to send results to Loïc et al.
o Jeremy Kerr: Device tree response to review comments, API.
Adding more platforms into device tree -- use device-tree
properties.
o John Stultz: OMAP emulation environment work -- preparation
for clock consolidation. Networking is not working.
First revision of POSIX clock RTC patch, working second
revision.
o Mounir Bsaibes: New presentation for blueprints, almost
done. Working on howto for writing specifications.
Tracking mechanism.
o Nat Waddell: Several Versatile Express bugs fixed last
week, especially frame-buffer tearing problem. Lorenzo's
kernel built and boots, but cannot get frame-buffer display
working. Device-tree problem? [Follow up with Lorenzo.]
o Nicolas Pitre: Merge bug fixes for ARM, including some
GDB vector-page-backtrace problems (related to atomic
operations). Pulled upstream patches from mainline.
SECCOMP support -- syscall restrictions for untrusted
code.
Q: /dev/mem protection from Kees Cook? A: Might.
o Paul McKenney: TSC meeting. RCU bugs, priority boosting.
o Steve Sakoman: Expansion-board detection in uboot for
OMAP3, save environments for eMMC for boards lacking
flash memory, bring Panda support to latest 8-layer
boards just appearing (about 12 patches required).
Expect to submit upstream later this week.
o Dave Martin on holiday Thu through next week.
