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.
