Thank you for the issue
u-dma-buf uses linux kernel's dma_alloc_coherent() to allocate a buffer. The buffer capacity that can be secured by dma_alloc_coherent() is determined by the architecture, Linux kernel version, build parameters, and boot parameters. It's difficult to answer this question because I don't know what your system looks like. I'm sorry I couldn't help you.
I tried the above command, but it fails to create size more than 4MiB. Can you suggest any other alternative?
