I have looked at the jumbo frames issue, and it was already broken in Linux 4.12. Likely due to the commit: https://github.com/raspberrypi/linux/commit/b3e3893e1253692c3d2b8e8ebd5a26183ed30443 This had unintended consequences that I in no way understand: https://github.com/raspberrypi/linux/commit/2...
The published attack only works from another device that is already connected to your network, but the RPi is at risk and the firmware should be updated.
I don`t think the patches are in linux 4.4, but I have been using gadget mode on a model A with linux 4.9 (a prebuilt version is in firmware-next) and 'dtoverlay=dwc2,dr_mode=peripheral' added into config.txt
The pi camera uses a lot of power, but a webcam will use more. Dave Akerman could tell you how much, but he will also tell you that you need to test it for yourself. Six batteries should be enough, but you need to leave your payload running overnight to find out. It is an easy fix to use two cameras...
If you do want to compile for arm v7, remove this part of the code: https://github.com/intel-tbb/intel-tbb/blob/master/include/tbb/machine/gcc_armv7.h#L31 "include/tbb/machine/gcc_armv7.h" uses machine code that will only run on armv7, so the mistake in the source code is on this line: https://githu...
The latest news from Eben was " I've just come back from dinner with one of the vendors: one of the topics was getting A+ back in stock. I'd expect us to build some in March for April availability." - but they have sold more than a Millon Pi-3 since then, and cannot make Zeros fast enough. Start tes...
CONFIG_VMSPLIT is used to set the physical address of the RAM, so you have to use the "right" setting. That might be a kernel "bug" that could be fixed.
Eric Anholt is making good progress with open source hardware acceleration, and it is looking quite promising. Here is a CromiumOS build I made earlier:
