Hello. Some of you may remember I am trying to run Tizen 4.0 on my single board computer, but I still couldn’t display anything on my LCD. However, now it seems that I found what I have to do like followings:
1. Install my SOC’s GPU driver(SGX driver) and libdrm to test it. 2. Replace the original TBM/TDM backends (for exynos) with libtdm-dumb and libtbm-drm to use SGX driver. 3. Use dlogutil TBM/DBM to resolve the next problems… I started porting sequence from this image<http://download.tizen.org/releases/daily/tizen/unified/tizen-unified_20171228.4/images/standard/mobile-wayland-armv7l-tm2/> that I downloaed from ‘release.tizen.org”. (Tizen 4.0 image for mobile-wayland-armv7l-tm2). I created image via MIC and flashed it with ‘dd’ command. However, I tested this image with my SMACK enabled kernel (4.4version), there were a lot of SMACK audit message like below; Also, because the TI-provided GPU driver installer should be run on my board (not host), I need to find the way to change smack policy on my board. In summary, could you give some advices once again for these questions?: 1. The way to change SMACK policies for files that I have to install on my board such as device drivers. 2. The reasony why the original Tizen-privided programs such as “key-manager” or “contextd” violate SMACK policy, and how to resolve it. Thank you very much in advance and happy new year! Best Regards. Heecheol Yan.g P.S: following is part of my booting log. It would be very appreciate if someone check it. Thanks a lot! 'systemctl status display-manager.service' for details.
