From b10066842680c996f45295b3b1130e7b08735a7f Mon Sep 17 00:00:00 2001 From: Alexandros Frantzis Date: Thu, 25 Oct 2018 17:32:36 +0300 Subject: [PATCH] clients: Add simple-dmabuf-egl Add a client that uses EGL/GLESv2 to draw to dmabuf buffers, utilizing EGLImages and FBOs. The client uses GBM to create the dmabufs buffers. The simple-dmabuf-egl client is partly based on patch [1] that changes dmabuf clients to use GBM instead of libdrm code, but has been greatly simplified since in this case we don't require direct pixel access or non-RGBA formats.
