I compiled the RC2 of kernel 4.15 today and the hardware 3D acceleration works with SWIOTLB disabled. You don't need the drm ttm patch anymore. 
but - well- every time i have no clue again how to do it.Hi Michael,MichaelMerkel wrote:hi.
sorry to ask but is there somewhere a list of the following available:can we maybe make this a sticky topic here in the board?
- list of available kernels & download
- list of available linux images or live dvds
- most important: a description how to boot/start/install the (different) kernels and images
from time to time i'm in the mood to test a linux version here on my x1000
thanks and regards
michael

You can find all the kernels, images, and ISOs on the following website: http://www.supertuxkart-amiga.de/amiga/x1000.html#downloads. You can test our ubuntu MATE 16.04 live DVD if you like.
No problems here.Download: vmlinux-4.15-rc2-AmigaOne_X1000_X5000.tar.gz
Please test it.
How can I do it? Unfortunately I am not the admin here.MichaelMerkel wrote: can you maybe post this sticky at the top of the forum? would be quite usefull for all.
I haven't tried it yet. You can try it if you like and post if it works.MichaelMerkel wrote: i guess the live "dvd" can also be used from a pen drive?
The openSUSE images are live images. You can copy them to USB sticks and boot from.MichaelMerkel wrote: hmm...
so are the other images, like the opensus ones (http://www.supertuxkart-amiga.de/amiga/ ... nsuse.html) no "live" dvds? only usefull for installation? i thought theses days all of the linux distros can be run out of the box for testing? just to understand.
