Re: [Dev] References images that contains libtbm-dumb and libtdm-drm
ENABLE_PP is the one of libtdm-drm's features. So you don't need to
disable it because it's just SW fallback functionality for something
which HW doesn't support.

Hi all.
Thank you for your advices.
I checked what many people said to me in previous mails and (as you
may expected) there were some strange things in my boot logs.
1. There was no ENABLE_PP configuration in my Linux kernel
configuration. I am currently using 4.4 mainline. What is the
purpose of this option?
2. When I tested dlogutil ‘TBM’ and ‘TDM’, the both commands print
the same error messages:
root@localhost:~# dlogutil TDM
Error: Could not connect to socket /run/dlog/main.ctl!
Error: Could not connect to socket /run/dlog/system.ctl!
Error: Could not connect to socket /run/dlog/apps.ctl!
3. As shown in attacted boot log, there are a lot of ‘SMACK-related
error messages’. In fact, I think it is actually the first
challenge I should address:
[ 605.475902] audit: type=1300 audit(946685404.800:282):

I am very sorry bothering all you with asking basic and tedious qustions.
I really appreciate of your help.

It seems libtbm-dumb and libtdm-drm should work fine as you said.
But, sometimes we face the unexpected problem when testing new target
device.
Could you check if any TBM or TDM error logs are in your board? you
can check them with "dlogutil TBM" and "dlogutil TDM".

This board supports Linux mainline kernel wirh board-specific

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

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.

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.

You can refer to below porting guide. https://wiki.tizen.org/Tizen_3.0_Porting_Guide 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. http://download.tizen.org/releases/milestone/tizen/4.0.m1/tizen-unified_20170529.1/repos/standard/packages/armv7l/ What hardware and Linux kernels are you using? If you give me more details about your env. then I may give you more advices.
