I'm using eglCreateImageKHR to create EGLImageKHR to return nullptr.

Can help to point out the BUG or provide a TDA4VM platform create the Simple Code of EGLImageKHR ?

- - code - - -

// /dev/dri/renderD128

// /dev/dri/by-path/platform-4e20000000.gpu-card

// /dev/dri/by-path/platform-4e20000000.gpu-render

int drmfd = open("/dev/dri/by-path/platform-4e20000000.gpu-render", O_RDWR, 0);

struct gbm_device *gbm_dev = gbm_create_device(drmfd);

struct gbm_bo* gbmbo = gbm_bo_create(gbm_dev, swidth, sheight, GBM_FORMAT_ARGB8888, GBM_BO_USE_RENDERING);

uint32_t bostride = gbm_bo_get_stride(gbmbo);

void *addr, *map_data;

addr = gbm_bo_map(gbmbo, 0, 0, swidth, sheight, GBM_BO_TRANSFER_READ, &bostride, &map_data);

unsigned int offset = 0;

EGLint attr[] = {

EGL_WIDTH, swidth,

EGL_HEIGHT, sheight,

EGL_LINUX_DRM_FOURCC_EXT, DRM_FORMAT_RGBA8888,

EGL_DMA_BUF_PLANE0_FD_EXT, drmfd,

EGL_DMA_BUF_PLANE0_OFFSET_EXT, offset,

EGL_DMA_BUF_PLANE0_PITCH_EXT, swidth * 4,

EGL_NONE,EGL_NONE

};

PFNEGLCREATEIMAGEKHRPROC eglCreateImageKHR;

eglCreateImageKHR = (PFNEGLCREATEIMAGEKHRPROC)eglGetProcAddress("eglCreateImageKHR");

EGLDisplay disp = eglGetCurrentDisplay();

EGLImageKHR imageKHR = eglCreateImageKHR(disp, EGL_NO_CONTEXT, EGL_LINUX_DMA_BUF_EXT, NULL, attr);

the imageKHR I got was a nullptr, but there was no error log.

Hello,

Thank you for reporting. While we look into your code on TDA4, I want to point you to an example that can be used as a reference for EGLImage in general:

https://git.ti.com/cgit/glsdk/omapdrmtest/

You can refer to util/display-kmscube.c as an example. We will also try and publish a simpler example.

Regards

Hemant

Thank you for providing simple, I encountered a compilation error while referring to omapdrmtest.

main.cpp:(.text+0x2a8): undefined reference to `omap_device_new(int)'

I confirm that I have successfully connected these SO's. Is this library working in TDA4 rootfs7.2?
libc.so，libdrm.so，libdrm_omap.so，libdrm_freedreno.so

----code-----

int main()
{

struct display_kmscube *disp_kmsc = NULL;
struct display *disp;
int ret, i, enabled = 0;
float fov = 45, distance = 8, connector_id = 4;

disp_kmsc = (struct display_kmscube *)calloc(1, sizeof(*disp_kmsc));
if (!disp_kmsc) {
ERROR("allocation failed");
goto fail;
}

disp_kmsc->gl.distance = distance;
disp_kmsc->gl.fov = fov;
disp_kmsc->user_connector_id = connector_id;
disp = &disp_kmsc->base; // 其中包含了egldisplay

for (i=0; i<MAX_FACES; i++) {
pthread_mutex_init(&disp_kmsc->lock[i], NULL);
}
pthread_mutex_init(&disp_kmsc->init_lock, NULL);

disp->fd = open("/dev/dri/by-path/platform-4e20000000.gpu-render", O_RDWR);
if (disp->fd < 0) {
ERROR("could not open drm device: %s (%d)", strerror(errno), errno);
goto fail;
}

disp->dev = omap_device_new(disp->fd);

Hello,

Sorry for not being clear. I had shared the link for code reference only. Like I mentioned, we are working on a simpler example tried on TDA4. I will update you as soon as we have that.

Regards

Thanks, I'm looking forward to it.
Looking forward to a solution on rootfs7.2.

hello
I'm still curious, Libdrm_freedreno. so and libdrm_omap.so 'are not available, I guess because the function parameters in. H and so are not aligned. (rootfs7.2)
