This is the first report about Igalia<\/a>\u2019s activities around Computer Graphics<\/a><\/a>, specifically 3D graphics<\/a> and, in particular, the Mesa3D Graphics Library<\/a> (Mesa), focusing on the year 2018.<\/p>\n\n\n\n

GL_ARB_gl_spirv and GL_ARB_spirv_extensions<\/h2>\n\n\n\n

GL_ARB_gl_spirv<\/a> is an OpenGL<\/a> extension whose purpose is to enable an OpenGL program to consume SPIR-V<\/a> shaders. In the case of GL_ARB_spirv_extensions<\/a>, it provides a mechanism by which an OpenGL implementation would be able to announce which particular SPIR-V extensions it supports, which is a nice complement to GL_ARB_gl_spirv.<\/p>\n\n\n\n

As both extensions, GL_ARB_gl_spirv and GL_ARB_spirv_extensions, are core functionality in OpenGL 4.6<\/a>, the drivers need to provide them in order to be compliant with that version.<\/p>\n\n\n\n

Although Igalia picked up the already started implementation of these extensions in Mesa back in 2017, 2018 is a year in which we put a big deal of work to provide the needed push to have all the remaining bits in place. Much of this effort provides general support to all the drivers under the Mesa umbrella but, in particular, Igalia implemented the backend code for Intel<\/a>‘s i965<\/a> driver (gen7+). Assuming that the review process for the remaining patches<\/a> goes without important bumps, it is expected that the whole implementation will land in Mesa during the beginning of 2019.<\/p>\n\n\n\n

Throughout the year, Alejandro Pi\u00f1eiro<\/a> gave status updates of the ongoing work through his talks at FOSDEM<\/a> and XDC 2018<\/a>. This is a video of the latter:<\/p>\n\n\n\n
