Re: Moving Linux kernel to 4.14

Updated to upstream 4.14.1. Also includes some missing commits from this PR.
Also added a commit that fixes the gpio numbering to start from zero which could fix asavah's issue.
As usual, to update run:

It seems that the papirus overlay and tinydrm defconfig from PR 2119 didn't make it over to rpi-4.14.y (the drivers are present).
Commits are cherry-picked (but untested) to 4.14 tree. Will be in next rpi-update.

Moving Linux kernel to 4.14

We are planning to move to the 4.14 kernel in the near future. One advantage is there is a lot more raspberry pi specific support in the newer upstream kernels which reduces the number of downstream raspberry pi patches and so reduces maintenance effort. The 4.14 kernel is planned to be an LTS kerne...

Re: Kodi does not start on PI 3

OSMC has separate images for Pi0/1 and Pi2/3. You need to run the correct image.

For help in transferring existing setup to the new Pi2/3 image you should ask here:

Re: OpenArena package

its not running at all is there a fix for this? It probably uses the firmware gl drivers (e.g. /opt/vc/lib/libEGL.so) which have now been renamed to /opt/vc/lib/libbrcmEGL.so). Ideally the openarena package should be rebuild with new libs names. For now: cp /opt/vc/lib/libbrcmEGL.so /opt/vc/lib/lib...

How should I interpret get_throttled=0x10000 or 0x30000 ? 0x10000 means low voltage has occurred 0x30000 means low voltage has occurred and arm frequency has been capped (due to temperature over 80'C). Normally low voltage will trigger throttling of turbo, but that can be disabled with "avoid_warni...

Did you enable the (experimental) GL driver? It's not compatible with omxplayer (or anything else using the GPU).
Setting gpu_mem=16 would be another way of stopping omxplayer working in this way.

Re: Under-voltage warnings

If the power drops below the voltage threshold are brief (e.g. a few milliseconds) then you won't spot it on the LED.
But get_throttled has some persistence (matching the visible warning symbol) so it will show any undervoltage events that occurred recently (~ 1 second).
