AM4378: Building git://git.ti.com/graphics/omap5-sgx-ddk-um-linux.git without Wayland

Hello,

Could you please share your build instructions and the config version that you are using processor-sdk-<version>-config.txt?

Regards,
Krunal

hi Krunal, 

thank you for your answer. 
We build with Yocto, we have developed a recipe that fetches the sources with:

BRANCH = "ti-img-sgx/rocko/1.14.3699939"

SRC_URI = "git://git.ti.com/graphics/omap5-sgx-ddk-um-linux.git;protocol=git;branch=${BRANCH}"
SRCREV = "bc62c9d0c590dfbc801bf6b10176c3a8b6a39d98"

and deploys the binaries on the target:

do_install () {
    oe_runmake install DESTDIR=${D} TARGET_PRODUCT=${TARGET_PRODUCT}
    mkdir -p ${D}${libdir}/gbm
    ln -sf ../libpvrGBMWSEGL.so.${PV} ${D}${libdir}/gbm/gbm_pvr.so
    ln -sf libGLESv2.so.${PV} ${D}${libdir}/libGLESv2.so.1

    rm -f ${D}${libdir}/pkgconfig/wayland-egl.pc

    chown -R root:root ${D}
}

The config is processor-sdk-05.02.00.10-config.txt.

Hello,

I am wondering if you could please try building the rootfs with the instructions mentioned in the following page. On my setup, I used the 05.02.00.10 config and added DISTRO_FEATURES_remove = "wayland" in the conf/local.conf file. The "tisdk-rootfs-image" built was successful and I do not see any Weston libraries in the rootfs/usr/lib folder.

Regards,
Krunal

Hi Krunal,

those are the instructions that I have followed, and in fact  I have set DISTRO_FEATURES_remove = "wayland" in local.conf, as I have already written in my first post.

What branch are you using? The binary "/usr/bin/pvrsrvctl" provided by git://git.ti.com/graphics/omap5-sgx-ddk-um-linux.git (branch ti-img-sgx/rocko/1.14.3699939)  definitely links to libwayland-server.so.0, since I get the error:

ERROR: libgles-sgx-0.1-r32 do_package_qa: QA Issue: /usr/bin/pvrsrvctl contained in package libgles-sgx requires libwayland-server.so.0, but no providers found in RDEPENDS_libgles-sgx? [file-rdeps]

Also please look at the output of "readelf -d" run on the binary file pvrsrvctl from the repository omap4-sgx-ddk-um-linux.git, branch ti-img-sgx/rocko/1.14.3699939:

readelf -d ./targetfs/ti437x/bin/pvrsrvctl

Hello,

Thank you for sharing the above information and as you mentioned, the driver requires the libwayland-server.so.0 library. I have attached the default GPU recipe and it has wayland defined in the section "DEPENDS" and "RDEPENDS". Based on my test, adding wayland will only generate the following shared libraries:

libpvrws_WAYLAND.so
libpvrws_WAYLAND.so.1
libpvrws_WAYLAND.so.1.14.3699939
libwayland-client.so.0
libwayland-client.so.0.3.0
libwayland-cursor.so.0
libwayland-cursor.so.0.0.0
libwayland-server.so.0
libwayland-server.so.0.1.0

Also, on our default SDK, we have enabled Weston (implementation of a Wayland) and setting "DISTRO_FEATURES_remove=wayland" will cause Weston to not build. I have also attached the tar ball of my generated rootfs.

Krunal

Hi Krunal,

thank you for your answer.

The recipe that you shared is the same one that we are using for building. Unfortunately the problem remains: the prebuilt binaries are linking to wayland. 

Can we have pre-built binaries that do not require wayland shared libraries?

Hello,

Let me check internally if that is possible and I will get back you within 48hours.

Regards,
Krunal

Hi,

sounds good, thank you!

Best,

Valentina

Hello Valentina,

Currently, I am discussing with our GPU vendor (Imagination) about the Wayland dependency. It seems like starting DDKv117(PSDK6.x), the dependency no longer exists. Once I hear back from Imagination, I will update the current ticket. Also, if possible, I would look into migrating to PSDK6.x.

Regards,
Krunal

Hi Krunal,

if you can assure us that DDKv117(PSDK6.x) is compatible with AM4378 then we can consider using that one.

Best,

Valentina

Hi Valentina,

It is compatible and here is the download page for AM437x: https://software-dl.ti.com/processor-sdk-linux/esd/AM437X/latest/index_FDS.html.

Regards,
Krunal

Hi Krunal,

I have realized that I haven't indicated the correct component version because I could not find AM438x in the form suggestions when I opened the ticket.

Could you please check again with Imagination which is the right version of git://git.ti.com/graphics/omap5-sgx-ddk-um-linux.git and which SDK should we use for AM438x?

Best 

Valentina

Hi Krunal,

I have tried to start a new thread with the right part number AM438x, and I can confirm that the part number that we have purchased can't be selected. See image below:

Hi Krunal,

could you please get back to me on my latest request?

Best,

Valentina

Hello Valentina,

I apologize for the delayed response and I was having internal discussions about the AM438x device. I did not know it was a secure device and the last release was PSDK5.2 (DDKv114).

With regards to your initial Yocto recipe errors, could you please share the command you are using to build sgx libs. The recipe `libgles-sgx` name doesn’t sound familiar and is that your custom recipe? If yes, please add Wayland as a dependency and make sure you clean your build before executing a build command.

Regards,
Krunal

Hello Valentina,

Thank you for sharing your recipe. On my setup, if I remove wayland dependency, I am able to replicate the pvrsrvctl errors. Based on my internal discussion, pvrsrvctl binary has linked dependency to Wayland. After adding Wayland to my recipe, the build was successful. I am wondering if you could please try to build the recipe again with Wayland included. If you still observe Wayland errors, I would recommend to clean your current build and try building again. 

Regards,
Krunal 

Hi Krunal,

thank you for your message.

Of course I can build with Wayland enabled, but the point is that we must get rid of it, as our GUI doesn't use it at all, therefore it's a dependency that we don't need.
When we purchased this product, we have been assured that the SGX/PVR engine can be used without Wayland.

Best,

Valentina

Hi Valentina,

Thank you for the clarification and internally, I have also been discussing with Fred. I will need some time to discuss with our internal SW team and I will give you a status update by mid next week.

Regards,
Krunal

Hi Krunal,

thank you! Looking forward to hearing back from you.

Best,

Valentina

Hello Valentina,

Thank you for your patience. I have created an experimental libraries and shared with Fred. He will share them shortly and please run your GUI and let me know if you run into any errors.  

Regards,
Krunal

Hi Krunal,

as you requested, below you can find the output of `eglinfo` after loading the kernel module `pvrsrvkm.ko` and starting the `pvr.service`. Please also note that at this point our application hasn't been launched.

Do you think that the binaries that you have pre-compiled for us don't work in our system because they are not aligned with the kernel module that we are using?
This is the info about our version of pvrsrvkm.ko:

Hi Valentina,

Please correct me if I am wrong but eglinfo ran successfully the second time you executed the function. Could you please confirm that no other application was accessing the display when you ran eglinfo?

Regards,
Krunal

Hi Krunal,

yes eglinfo ran successfully and no other application was accessing the display when I ran it.

Hello,

Thank you for the confirmation and I believe that the libraries provided to you are correct. If there was a mismatch, you would not have been able to run eglinfo or your custom application. Since you are running a system without Wayland, you could only have one DRM master and if two applications try to access the display at the same time, the " Couldn't set CRTC: Permission denied" error is observed. 

Based on our previous discussion, I believe you are writing a script to make sure the GPU is successfully initialized. I usually run the following commands:
root@am335x-evm:~# /etc/init.d/rc.pvr stop
Unloaded PowerVR consumer services.
root@am335x-evm:~# /etc/init.d/rc.pvr start
[ 1054.194292] [drm] Initialized pvr 1.17.4948957 20110701 for 56000000.sgx on minor 1
[ 1054.255388] PVR_K: UM DDK-(4948957) and KM DDK-(4948957) match. [ OK ]
Loaded PowerVR consumer services.

As long as no "PVR:(Error)" messages are observed and the "Loaded ... services" message occurs, it gives me a good indication that the GPU is initialized and ready to be used. Please keep one thing in mind, if you have any application using the GPU, you will not be able to stop the service. Here is an example:

Ideally, make sure that no one is using the pvrsrvkm module before closing it.
