Hello
LINUX SDK：7.2
In TDA4, can shared pointers be used across processes? roughly as follows
1. Process 1, allocate memory through tivxMemBufferAlloc(&mem, CAM_SIZE, (vx_enum)TIVX_MEM_EXTERNAL)
2. Send mem to Process 2
3. How to use the virtual address corresponding to mem.shared_ptr in process 2?
4. Is the file descriptor mem.dma_fd valid across processes?
Regards
Hello Nikhil
Thank you. The method you recommended can be used. I can allocate memory in process 1 and read it through the CPU in process 2。
My process 2 is a rendering process. I tried to bind the dmafd passed from process 1 to eglimage, but this error was reported.
Process 2 is as follows:
1. get fd from Process 1
2. get virtual ptr use tivxMemTranslateFd ，use cpu check data is right
3. create eglimage use dmafd
Please help to see what the problem is
Regards
Daming
