AM5728: GPU driver for Xorg

Farrukh Iqbal Sheikh

Part Number: AM5728

Dear all,

I was trying to install Xorg compatible GPU driver on my Sitara AM5728 IDK. I came to know that there is a GPU driver source file in a folder "ti-sgx-ddk-km-1.14.3699939", which comes with the TI SDK for Sitara AM57xx SoC. I have managed to compile the source and this process produced two kernel modules file "bc_example.ko and pvrsrvkm.ko" as an output. I have loaded these kernel modules, as you may see in the lsmod snapshot below

My questions are as follows:

1) Will TI provided GPU driver sources produce only two kernel modules files as mentioned above or Will it also produce some additional files too? If it produce additional files, then what are those files and how can they be obtained?

2) There is also http://processors.wiki.ti.com/index.php/Graphics_SDK_Quick_installation_and_user_guide#Xorg_build which is a complete Graphic SDK provided by TI. However, it seems that this is not compatible to AM5728 SoC. Could you send me the link of such Graphic SDK for AM5728 IDK?

3) If these two kernel modules are the only driver files needed, then how can I configure Xorg to use this driver?

Look forward to receiving your response.

Hi, Farrukh:

TI does not support Graphics SDK anymore, instead, all graphics related modules are included at the PSDK Linux distribution. The graphics release consists of a DDK Kernel Module (KM) source package and a DDK User-mode Module (UM) binary-only package.

There are three EGL window system (WSEGL) supported by the DDK UM libraries.

libpvrDRMWSEGL.so (for VSync synchronised writes to DRM Framebuffer - slower, but avoids tearing) (for eglfs)
libpvrGBMWSEGL.so (for eglfs_kms)
libpvrws_WAYLAND.so (for wayland-egl)

The window system will be dynamically loaded by DDK based on the application use case, so that the PVR configuration parameter WindowSystem at the PVR configuration file /etc/powervr.ini is optional.

As you may notice that the graphics DDK no longer supports X11. Please refer to "software-dl.ti.com/.../Foundational_Components.html details.

If your application is based on QT5 then it should be able to run on top of any QT QPA (platform) supported by the underneath EGL components.

wayland-egl (default)
eglfs (-platform eglfs)

Attached please find the DDK UM package for your reference.

Best regards,

Eric

Hi Eric,

May I know the reason of not supporting X11?

Best regards,

Hi, Farrukh:

Here is a short summary why TI stop supporting X11 from our graphics expert.

1. X11 is quite bloated with features that are not necessary for modern day embedded systems. This increases memory footprint and reduces performance

2. Wayland is clearly the future with open source frameworks like Qt5 and industry alliances like Genivi/Tizen adopting Wayland
•Qt5 - wayland.freedesktop.org/qt5.html
•Genivi •projects.genivi.org/.../about
•events.linuxfoundation.org/.../ALS_201310_tanibata_v04.pdf
•Tizen - www.tizen.org/.../lfcs2012_barnes.pdf

3. Embedded systems have been full screen applications till recent times. Window management with Wayland is still a big step forward.

4. Customizing X11 for feature additions is a major undertaking due to the extensions and backward compatibility.

For someone coming from an embedded system background typically with full screen applications, the whole argument for Wayland seems quite natural argument and logical. Only when we look at it from a desktop history, the argument for X11 is admissible due to legacy applications.

He also went through some X11 history if your are interested.

Best regards,

Eric

Hi Eric,

I hope that you are doing fine. Could you please have a look at the log in below and suggest an appropriate solution? we have tried till here by creating a symlink omapdrm_dri.so to gbm_pvr.so and we still have the issue.

1) May I know, did you do some customisation in weston src in order to make use of gpu driver?

Hi, Farrukh:

For processor SDK 5.x, the Weston version is 2.0.0 and it is built through yocto on rocko branch.
There are two major differences between the ABB build and TI build based on the weston.log.
1. Different libgbm
Please refer to the libgbm 10.0.0 provided by yocto, which has been modified to support PVR.
backend.c:
/* a more clever scheme would be to discover backends in a certain
* directory..
*/
static const char *backends[] = {
"gbm_dri.so",
"gbm_gallium_drm.so",
"gbm_pvr.so",
};

static const void *
load_backend(const char *name)
{
char path[PATH_MAX];
void *module;
const char *entrypoint = "gbm_backend";

if (name[0] != '/')
snprintf(path, sizeof path, MODULEDIR "/%s", name);
else
snprintf(path, sizeof path, "%s", name);

module = dlopen(path, RTLD_NOW | RTLD_GLOBAL);
if (!module) {
fprintf(stderr, "failed to load module: %s\n", dlerror());
return NULL;
}
else {
fprintf(stderr, "loaded module : %s\n", name);
}

return dlsym(module, entrypoint);
}

Here is the corresponding Weston log:
[02:15:33.405] Loading module '/usr/lib/libweston-2/gl-renderer.so'
failed to load module: /usr/lib/gbm/gbm_dri.so: cannot open shared object file: No such file or directory
failed to load module: /usr/lib/gbm/gbm_gallium_drm.so: cannot open shared object file: No such file or directory
loaded module : gbm_pvr.so
found valid GBM backend : gbm_pvr.so

2. Mesa vs. openGLES direct calls
The SGX DDK UM libraries support direct EGL and GLES calls without Mesa. All the graphics module should be built with the SGX DDK UM libraries provided by PLSDK (and without Mesa).

Hi Eric,

(I'm working with Farrukh on this, so I'm following up here)

we managed to address point number 1 from your reply, and we can now load a valid GBM backend:

Loading module '/usr/local/lib/libweston-5/gl-renderer.so'

loaded module : gbm_pvr.so

found valid GBM backend : gbm_pvr.so

(full log attached)

However, point 2 is still tricky, and we get a segmentation fault without weston starting at all. Which modules should we build (without mesa) to have weston running?

Thanks a lot.

Ettore

Hi, Ettore:

It is excellent that the SGX DDK is recognized and linked now. We need to resolve the following three errors, in particular, the first one now.

[06:27:18.862] failed to choose EGL config for output
[06:27:18.863] failed to create egl surface
[06:27:18.863] failed to create gl renderer output state

You may need to make the similar changes according to the patch (renamed to .txt) attached.

Best regards,

Eric

Subject: [PATCH 2/4] weston: Allow visual_id to be 0

The inquiry of visual id from egl API eglGetConfigAttrib(EGL_NATIVE_VISUAL_ID)
is an optional feature. The visual id will be set to 0 if this feature is
not supported. Therefore, the return condition @function match_config_to_visual()
should be (id == visual_id || id == 0) instead of (id == visual_id)

Hi Eric,

I patched weston (both 2.0.0 and 4.0.92) with your changes and recompiled.
The signature in both versions is different from your patch, since I have "match_config_to_visual(EGLDisplay egl_display, EGLint visual_id, EGLConfig *configs, int count)" and you have "match_config_to_visual(EGLDisplay egl_display, &id))".

However, I still get errors in both cases, as you can see by the logs here:

Hi, Ettore:

Is the new test result with the recommended patch? It looks like the following issues are resolved by the patch.

[06:27:18.862] failed to choose EGL config for output
[06:27:18.863] failed to create egl surface
[06:27:18.863] failed to create gl renderer output state

The new error "Connection reset by peer" might still be some kind of build issue. You need to check with the WAYLAND community to see what it actually means and what may cause that kind of problem. I shall look into it when I get a chance as well.

Best regards,

Eric

Hi Eric,

I confirm that the previous problem with EGL was solved by applying the patch.

However, I still get the following (end of weston.log only):

Would you have any suggestion?

Hi, Ettore:

It is a wired one that I have not encountered before. I have forward the log to another engineer who may be able to give us some hints.
To see whether it is a problem introduced by the new version of Weston, can you try Weston 2.0 with the patch attached?

Best regards,

Eric

Subject: [PATCH 1/4] udev-seat: restrict udev enumeration to card0

In case of separate GPU and Display devices as found in embedded systems, we
could have modeset node and render node controlled by different drivers.
There is a distinct possibility that udev enumeration returns the DRM device
corresponding to render node as the primary DRM device.

Obviously, modeset operations cannot be done on the GPU DRM device.

Restrict the udev enumeration to card0 and ensure that DRM device corresponding
to display is returned as the primary DRM device.

Hi Eric,

I tried with weston 2.0.0 plus patch, but unfortunately the output is the same (log attached).

Thanks,

Ettore:

The root cause of the problem might be the Segmentation fault and the rest of errors are just side effects.
Can you use gdb to debug the segmentation fault?

Here is a link to a Web post regarding the similar issue: lists.freedesktop.org/.../013044.html.

Best regards,

Hi Eric,

if I run weston with gdb, I only get to the segfault without core dump...

By looking at the weston code, it looks like the errors are in windows.c, in particular in

struct display *

display_create(int *argc, char *argv[])

did you have more patches applied there?

Thanks,

Ettore

TI__Intellectual 2810 points

Hi, Ettore:

Please refer tosoftware-dl.ti.com/.../Overview.html for PLSDK build procedure. After you clone and configure the oe-layersetup.git, all the Weston patches can be found under sources/meta-arago/meta-arago-distro/recipes-graphics/wayland\Weston, which is also attached here for your reference. There is no patch regarding windows.c.

To debug the problem with gdb, you need to install the corresponding ipk such as weston_2.0.0-r0.arago29_armv7ahf-neon.ipk and libweston-2_2.0.0-r0.arago29_armv7ahf-neon.ipk. on the target machine or you can add weston_log() at the Weston source code.

Best regards,

Eric
