G2D plugins don't work

Hello,

I'm trying to make G2D plugins from gstreamer-imx work with my imx6q. I work on Yocto, fido branch, with 3.14.38 kernel.

These plugins are from https://github.com/Freescale/gstreamer-imx. When I try to run gst-launch-1.0 imxv4l2videosrc ! imxg2dvideosink I get the following error :

g2d_alloc: alloc memory fail with size 16!
ERROR: Pipeline doesn't want to pause.
Setting pipeline to NULL ...
Freeing pipeline ..

With more debug :

0:00:00.540714000 425 0x549400 INFO imxphysmemallocator phys_mem_allocator.c:62:gst_imx_phys_mem_allocator_init:<GstImxPhysMemAllocator@0x54d908> initializing physical memory allocator g2d_alloc: alloc memory fail with size 16! 0:00:00.556959667 425 0x549400 ERROR imxg2dallocator allocator.c:59:gst_imx_g2d_alloc_phys_mem:<imxg2dallocator0> could not allocate 16 bytes of physical memory 0:00:00.557108000 425 0x549400 WARN imxphysmemallocator phys_mem_allocator.c:154:gst_imx_phys_mem_allocator_alloc:<imxg2dallocator0> could not allocate memory block with 16 bytes 0:00:00.557213000 425 0x549400 WARN GST_BUFFER gstbuffer.c:739:gst_buffer_new_allocate: failed to allocate 16 bytes

I posted an issue on the github, but it's not solved.

I tried to change the CMA value, already to 320M to other values, but this the same error.

a part of my kernel configuration :

CONFIG_MXC_GPU_VIV=y
CONFIG_CMA_SIZE_MBYTES=320
CONFIG_CMA_SIZE_SEL_MBYTES=y
CONFIG_CMA_ALIGNMENT=8
CONFIG_CMA_AREAS=7
CONFIG_DMA_CMA=y
CONFIG_DMA_SHARED_BUFFER=y

I think it would be a kernel missconfiguration. I work on another iMX (DL) and these plugins just work fine with yocto fido. Any thougts about kernel missing configuration?

Best Regards
