It was a pretty miserable several hours I spent trying this . . . It appears that James used the latest TTM API, so it cannot practically be compiled with Linux kernel anything older than 3.18 without some rewriting. Considering that VIA Technologies hardware we are dealing here is not state of the art unlike stuff from NVIDIA, AMD, or Intel (in no particular order), I will be philosophically against using the latest API. If the older API is adequate, I will be inclined to sticking to it, unless there are technical reasons to using the newer API for newer generation hardware or older the API was obsoleted. Anyway, just to make it somewhat easier to compile it against older Linux kernels, the newer DRM module should supply its own PCI device IDs, rather than using the ones from DRM header file or Linux PCI device ID header file. Due to this compilation issue, I probably will have to use a shorter support period Lubuntu for the newer DRM development like Lubuntu 15.10 for experimenting with my ZOTAC ZBOX nano VD01.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
