From 64deb9471c7d9cad4c2ec1de1fba6a35c9af8e68 Mon Sep 17 00:00:00 2001 From: Erik Kurzinger Date: Fri, 14 May 2021 08:26:49 -0400 Subject: [PATCH xserver 21/27] xwayland/eglstream: allow commits to dma-buf backed pixmaps MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As of commit 098e0f52 xwl_glamor_eglstream_allow_commits will not allow commits if the xwl_pixmap does not have an EGLSurface. This is valid for pixmaps backed by an EGLStream, however pixmaps backed by a dma-buf for OpenGL or Vulkan rendering will never have an EGLSurface. Unlike EGLStream backed pixmaps, though, glamor will render directly to the buffer that Xwayland passes to the compositor. Hence, they don't require the intermediate copy in xwl_glamor_eglstream_post_damage that EGLStream backed pixmaps do, so there is no need for an EGLSurface.
