Hi Eric, Denys

Thank you for answering.

I tried the following:
root@beaglebone:~# gles1test1
PVR:(Error): WSEGL_CreateWindowDrawable: Couldn't set CRTC: Invalid
argument [0, ]
'eglCreateWindowSurface' returned egl error 'EGL_BAD_ALLOC' (0x3003)
root@beaglebone:~# gles2test1
--------------------- started ---------------------
PVR:(Error): WSEGL_CreateWindowDrawable: Couldn't set CRTC: Invalid
argument [0, ]
'eglCreateWindowSurface' returned egl error 'EGL_BAD_ALLOC' (0x3003)

I also try other configurations, like core-image-weston. After "adjusting"
mesa so it won't install gbm, weston won't boot and I still errors.

here the weston output:
starting with no config
Loding module/usr/lib/weston/drm-backend.so
output repaint windows is 7 ms maximun
initilizing drm backend
using /dev/dri/card0
Loading module /usr/lib/weston/gl-rendered.so
...

found valid GBM backend : gbm_pvr.so
warning no EGL_EXT_platform_base support of specific platform; failling
back to eglGetDisplay
failed to choose EGL config

fatal: failed to create compositor backend


I think the problem is around the drm thing. I'm not an expert but:
when I look at /dev/dri/*, I see 2 card ( as if there is 2 drm driver)
root@beaglebone:~# ls -lsa /dev/dri/
     0 drwxr-xr-x    2 root     root           120 Jan  1  1970 .
     0 drwxr-xr-x   11 root     root         13160 Oct  6 04:22 ..
     0 crw-rw----    1 root     video     226,   0 Jan  1  1970 card0
     0 crw-rw----    1 root     video     226,   1 Jan  1  1970 card1
     0 crw-rw----    1 root     video     226,  64 Jan  1  1970 controlD64
     0 crw-rw----    1 root     video     226, 128 Jan  1  1970 renderD128


also
root@beaglebone:~# ls -lsa /sys/class/drm/card0/device/driver
     0 lrwxrwxrwx    1 root     root             0 Oct  6 04:31
/sys/class/drm/card0/device/driver ->
../../../../bus/platform/drivers/tilcdc
root@beaglebone:~# ls -lsa /sys/class/drm/card1/device/driver
     0 lrwxrwxrwx    1 root     root             0 Oct  6 04:35
/sys/class/drm/card1/device/driver ->
../../../../bus/platform/drivers/pvrsrvkm

1. So it sound that there is 2 drm drivers is it normal?
2. Should I change the device three to remove tilcdc, so the only drm
driver will be pvrsrvkm?
3. Is there something to do to ensure libdrm use the SGX driver?
