Re: [meta-ti] ti-sgx-ddk-um_1.14.3699939: check for wayland in DISTRO_FEATURES

[Ankur Tyagi]

Fair enough.

If Imagination has decided for the hard coded dependency, then they are
needed.

Re: [meta-ti] ti-sgx-ddk-um_1.14.3699939: check for wayland in DISTRO_FEATURES

[Ankur Tyagi]

Thanks for the info Eric.

So when wayland is removed from DISTRO_FEATURES, QT uses eglfs QPA and SGX
DDK UM uses
​
libpvrDRMWSEGL.so: EGLFS (Raw), then why hard coded dependency on wayland ?

Why to package libraries in target rootfs if they are not needed ?

Ankur

Re: [meta-ti] ti-sgx-ddk-um_1.14.3699939: check for wayland in DISTRO_FEATURES

[Ruei, Eric]

Hi, Denys:

Yes and yes, we do need the wayland  libraries to be present at the target file 
system because they are required by the SGX DDM UM binaries. 
The SGX DDK UM supports the following three (EGL) window systems and 
auto-detect which one should be used.
libpvrDRMWSEGL.so: EGLFS (Raw)
libpvrGBMWSEGL.so: Wayland-Server, DRM owner such as kmscube, or QT QPA 
EGLFS_KMS.
libpvrws_WAYLAND.so: Wayland Client

Best regards,

Eric

Thanks, Eric,

As I was suspecting, wayland libs are required to be present for SGX to work 
even in no-Wayland mode. Good thing OE detects those .so dependencies and 
automatically pulls them in for you.

Have you tried removing Wayland pieces from the rootfs after the fact? I'm 
guessing SGX would stop working due to dynamic linker/loader not being able to 
resolve all the dependencies hardcoded in .so...

Re: [meta-ti] ti-sgx-ddk-um_1.14.3699939: check for wayland in DISTRO_FEATURES

[Ruei, Eric]

Hi, Denys:

Yes, we can make PLSDK image with Weston disabled by removing wayland from the 
DISTRO_FEATURES list.
Conf/local.conf:
DISTRO_FEATURES_remove = "wayland"

Therefore QT will use eglfs as the default QPA.

However, some of the wayland related libraries and components are still present 
at the target file system.
There is no need to update ti-sgx-ddk-um_1.14.3699939 recipe and SGX should 
work by using libpvrDRMWSEGL.so.

Best regards,

Eric

I suspect it will try to link/load the needed wayland libs, but I haven't tried 
it myself.


Eric,

Since you've been playing with eglfs lately, can you please confirm/clarify 
whether SGX can work w/o Wayland?


> Old branch (daisy) was not having such dependency on wayland, may I know
> why it is now ?

The old 3D Graphics SDK supported 2 modes - X11 and raw FB. We haven't 
supported X11 for years. The new SGX DDK binaries are mostly for Wayland 
graphics stack, as far as I know, since that's what we support on our 
platforms.


Karthik,

Anything you want to add or clarify here?

Wasn't able to look at this one today. 
I will come back to you on this either tomorrow or latest by Monday.

I suspect it will try to link/load the needed wayland libs, but I haven't tried 
it myself.


Eric,

Since you've been playing with eglfs lately, can you please confirm/clarify 
whether SGX can work w/o Wayland?

The old 3D Graphics SDK supported 2 modes - X11 and raw FB. We haven't 
supported X11 for years. The new SGX DDK binaries are mostly for Wayland 
graphics stack, as far as I know, since that's what we support on our 
platforms.


Karthik,

Anything you want to add or clarify here?

Re: [meta-ti] ti-sgx-ddk-um_1.14.3699939: check for wayland in DISTRO_FEATURES

[Ankur Tyagi]

So even if I added "wayland" in DISTRO_FEATURES_remove, it would still be
packaged in resulting image.

I don't want to use x11, wayland and have also configured Qt to use eglfs
qpa. But it seems wayland will be used anyhow. Am I correct ?

Old branch (daisy) was not having such dependency on wayland, may I know
why it is now ?

regards
Ankur
