Linux: SgxFrmcpyLink : eglChooseConfig() success, but return 0 config.

Tool/software: Linux

Hi All,

We use custom h/w and software based on DRA74X and PROCESSOR-SDK-VISION 3.02, and we modify the SDK code to make the display route to Linux.

We are using SgxFrmcpyLink and with this we can get the offline rendered frame by DMABUF. However the solution return error because of eglChooseConfig() return 0 matching config, and eglCreateContext() failed with error code (0x3005). The reason for the problem is that there is no matching config for Specific attributes.

We found a total of  22 configs, below is the details.

#define EGL_OPENGL_BIT			0x0008	/* EGL_RENDERABLE_TYPE mask bits */

We do a little test on demo board(DRA7XXEVM) with running PROCESSOR-SDK-VISION3.02 or PROCESSOR-SDK-LINUX3.04. eglChooseConfig() return 3 matching configs successfully.

We have compared the kernel code and the graphics driver, they are the same. Only a little bit because of different h/w differences on device tree.

Is there anyone who can tell me how to solve this problem? 

regards, Jaye.

    Hi Yordan,

    Thank you for your reply.

    This thread is posted by my colleague. His description is not exactly right. I think it is necessary to post another thread to discuss this issue. I would advise my colleague to close that thread.

    The key to this issue is how eglGetConfigs() woks. where did eglGetConfigs() get those configs ?

    regards,Jaye.

    Hi Jaye,

    Let me understand.

    Are you saying you are using the same eglChooseConfig() code on Processor-SDK-Vision-3.02 and Processor-SDK-Linux-Automotive-3.04 but see different results on each?

    Regards,
    Anand

    Hi Anand,

    I test eglChooseConfig() and eglGetConfigs() code on both Processor-SDK-Vision-3.02 and Processor-SDK-Linux-Automotive-3.04 on DRA7XXEVM and see the same result. here is the result

        else
        {
            fprintf(stderr, " EGL: ERROR: EGL_DEPTH_SIZE: failed.\n");
        }
#endif

    	context = eglCreateContext(display, config, EGL_NO_CONTEXT, context_attribs);
        eglCheckError("eglCreateContext", EGL_TRUE);
        if (context == EGL_NO_CONTEXT) {
            fprintf(stderr, " EGL: eglCreateContext() failed !!!\n");
            return -1;
        }
	}
    return 0;
}

     

    By the way, our U-boot is a relatively old version, is  VERSION = 2014 PATCHLEVEL = 07, which used at VISION_SDK_2.09. I wonder if U-boot has any effect on this issue??

    Hi Jaye,

    I think the issue is occurring because the incorrect window system EGL is being picked up.

    We support 3 window system EGL layers on this SoC:
    1. GBM => used when GBM API is used for surface allocation and DRM/KMS API is used for display. Example application - git.ti.com/.../kmscube
    2. Wayland => used by Wayland clients. Example application - github.com/.../simple-egl.c
    3. Null DRM Window System => used as a null window system. EGL layer abstracts display management completely. Application only calls OpenGLES / EGL calls.

    Which EGL layer is your application using? We support PIXMAP only for GBM window system EGL. This is because Wayland EGL does not define a pixmap surface. Similarly, by definition, Null DRM window system talks to display directly and hence there is no pixmap / offscreen support.

    You can force the driver to pick up GBM by editing /etc/powervr.ini and adding the following 2 lines:

    [default]
    WindowSystem="libpvrGBMWSEGL.so"

    After updating the file on target file system, restart the board and start the test application. You should see a text that says using the WindowSystem apphint.
