From d284ac2d593725248e074bf9cbee2c44e76c38bd Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 3 Jun 2024 13:12:59 +0200 Subject: libcamera: software_isp: Allow using dma-buffers from /dev/udmabuf Allow the DmaBufAllocator used by the software ISP to use memfd() + /dev/udmabuf for the software ISP destination buffers. This is useful on Linux distributions where normal users are not allowed to access /dev/dma_heap/* while they are allowed to access /dev/udmabuf.
