Trying to get SGX libs to initialise

[Rob Voisey]

I have the drivers and latest libs installed, but still can't get this stuff
to run. eglInitialize is failing, and as the lib is closed source I can't
find out why. I'm running the latest OE build for Beagleboard (console, no
X, tho I installed libx11-6 as it was a dependency).

The pre-built demos all fail like this:

# Raw/TrainingCourse/Initialization/OGLES2Initialization
Error: eglInitialize() failed.

I made a very simple test app, and observed that:

eglGetDisplay((EGLNativeDisplayType)EGL_DEFAULT_DISPLAY) returns 1

eglInitialize(eglDisplay, &iMajorVersion, &iMinorVersion) returns EGL_FALSE

Note that I can open /dev/fb0 and run my own graphics routines on it with no
problem. I tried *not* doing so but that didn't help. I'm suspicious of
the boot arguments and tried a few variants, but admit I'm groping around in
the dark.

Thanks for any hints.

Change that to mr-16, sgx doesn't support 32bit.

Thanks, that did get me further. The call to eglInitialize no longer fails,
and a call to eglChooseConfig also succeeds, however eglCreateWindowSurface
then fails with EGL_NOT_INITIALIZED. I'm using the config attributes from
the lib examples:

EGL_SURFACE_TYPE = EGL_WINDOW_BIT
EGL_RENDERABLE_TYPE = EGL_OPENGL_ES2_BIT
EGL_CONTEXT_CLIENT_VERSION = 2

I remember why I hate closed source libraries now!

Rob,
  Where you got the SGX lib? Could you share with me?

You need to contact TI to get the libraries.

[Rob Voisey]

A bit more info:

The following tests execute without error:

sgx_init_test
sgx_blit_test
sgx_render_test

The following tests fail:

sgx_flip_test FAIL - PVRSRV_ERROR_TOOMANYBUFFERS
sgx_render_flip_test FAIL - PVRSRV_ERROR_TOOMANYBUFFERS(27)

All EGL/OGLES tests fail with code 3001, which I believe is
EGL_NOT_INITIALIZED, raised during eglCreateWindowSurface.

I've attached some output.

I'll have a dig into that kernel module error tomorrow, but if anyone has
any ideas I'd love to hear them.

You could try increasing the VRAM a bit in DSS2, that might help.

I went via the UK distributor, but the TI website offers this address:

Thanks, that didn't solve the problem. However TI suggested adding:

[default]
WindowSystem=libpvrPVR2D_FRONTWSEGL.so

to powervi.ini and this did work around the problem. At last I can get on
with some graphics development which is great news.

Ah right, the default is FLIP, which has no kernel support anymore.

That's great news. Does that mean that you can now run the 3D demos?

Please forgive my ignorance, but where is this .ini file to be found?
I have run a "find / -name p*.ini" on my Beagle and it came up with a
couple of ini files, neither of which is this one.

Yes. Some of them are quite pretty.

The ini file doesn't exist with the current distribution. Create it
yourself: /etc/powervr.ini

Don't forget you must also run with a 16-bit framebuffer (which is a
showstopper for me unfortunately).

Thanks, Rob.

I tried this but it didn't work - running strace showed that it was
still loading the "flip" library. I tried a couple of things, like
putting it in the current directory, to no avail. Perhaps some sort of
formatting issue?

However, you still gave me the vital information I needed.

I ended up copying the "frontwsegl" library I wanted over the "flip"
library. Dreadful, awful, hacky solution but it got me far enough to
run the demos. Now all I have to do is find a way to compile my own
game :-)
