Presently with SoftISP being CPU only - physically contiguous memory is not required.
Yes, I've misinterpreted what we discussed, udmabuf should be enough on qcom.
Bryan, will this still be true when you have a GPU based ISP ? Will that require physically contiguous memory ? Or will the mapping into the GPU handle any required translations?
I believe it should be fine because we do glTexImage2D on the way in ATM and have support for eglCreateImageKHR(.., .., .., .., .., EGL_DMA_BUF_PLANE0_FD_EXT, dma_fd); but in either case phys contig doesn't matter.
