Hello, thank you very much for your mail. I am using beaglebone black singleboard computer, which is based on TI's AM335x SOC.
This board supports Linux mainline kernel wirh board-specific patches and my kernel version is mainline 4.4 When I read your wiki section, I thought that I don't need to port the backends because the libtbm-dumb and libtdm-drm are for the modules to support the platforms which provieds standard drm interfaces like my board. Anyway, thanks a lot your help and I will check whether ENABLE_PP is set or not in my kernel. Best regards.

TBM and TDM backend are Tizen HAL modules dependent on Hardware and its kernel. So you would need to implement these HALs - TBM and TDM backends. You can refer to below porting guide. https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwiki.tizen.org%2FTizen_3.0_Porting_Guide&data=02%7C01%7C%7Ce93a83180cee4b804b2208d545b3dc0c%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636491561144249374&sdata=Qms2ux91lq%2FbIs4YYQ3Pev4F%2FIyN5%2BY4yaEYmypSh4A%3D&reserved=0 If your board uses mainline kernel which never include in-house code then you could use libtbm-dump and even libtdm-drm(by disabling ENABLE_PP config) packages below by installing them on your target. https://eur03.safelinks.protection.outlook.com/?url=http%3A%2F%2Fdownload.tizen.org%2Freleases%2Fmilestone%2Ftizen%2F4.0.m1%2Ftizen-unified_20170529.1%2Frepos%2Fstandard%2Fpackages%2Farmv7l%2F&data=02%7C01%7C%7Ce93a83180cee4b804b2208d545b3dc0c%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636491561144249374&sdata=P%2F5eu6jc5SdyiuFRKp9YwD0Fui4DV4s%2FsT3hTDWE6TQ%3D&reserved=0 What hardware and Linux kernels are you using? If you give me more details about your env. then I may give you more advices.
