Hi Leo,
>It would be better if you can extract the common code between bellagio and
tizonia to avoid the duplication.
This is something Gurkirpal and me discussed, like having
state_trackers/omx/common, state_trackers/omx/bellagio,
state_trackers/omx/tizonia. To anticipate that Gurkirpal sent an email
https://www.mail-archive.com/mesa-dev@lists.freedesktop.org/msg153562.html
during the Community Bonding period in May (a few weeks from the date
(early May) students are officially accepted to the date (end May) where
student actually starts working)
The problem with the directory layout above is that it would look like it
will be built together in the same shared library. This is not good because
it is suppose to export OMX_ComponentInit for each target. Of course this
would still be possible to have 2 shared libs but I believe in
state_trackers dir, all sub dir are for one target. Also we were afraid
that there would be other limitations so we decided to go for a separate
directory.
And since there were no objections in Gurkirpal's mail above we went this
way.
Now if I look into state_trackers/omx_tizonia, in fact the common code with
state_trackers/omx_bellagio does not have anything to do with omx. For
example "slice_header". Maybe it can be moved to gallium/auxiliary/vl/ like
it is done already for vl_rbsp_init. Same for omx_get_screen.
So I suggest this 'factorization' to be not a blocker for merging
state_trackers/omx_tizonia into usptream. But later on we can move
gradually bits from state_trackers/omx_bellagio to gallium/auxiliary. And
then make state_trackers/omx_tizonia use it as well.
This way you will only bother about maintaining state_trackers/omx_bellagio
the time being. This also allows to not slowly get its work lost.
Of course we would have done differently if we knew advance. But as today
Gurkirpal won't have enough time to do this factorization/move as the
project ends in 1 week. Having all of this merged in upstream is not
mandatory to succeed the project but Gurkirpal will need some rest after
these 3 months of hard work. And who knows what happens after, whether he
will still be around after sometimes or not. And this is entirely up to him.
So again I suggest this factorization/move not to be a blocker for the
reasons above. What do you think?
Thx
Julien
