Intel's New OpenGL Driver Is Looking Really Great With The Upcoming Mesa 19.2

[jf33]

What about feature parity? Are there OpenGL extensions supported by the classic driver that do not yet run on the Gallium3D driver? I would like to see the new driver on mesamatrix.net.

What about feature parity? Are there OpenGL extensions supported by the classic driver that do not yet run on the Gallium3D driver? I would like to see the new driver on mesamatrix.net.

Here is the list of extensions i965 supports but iris is missing:

• GL_ARB_gl_spirv & GL_ARB_spirv_extensions
  (newly landed, these will come to iris shortly)
• GL_MESA_framebuffer_flip_y
  (should be added, nobody working on it AFAIK)
• GL_3DFX_texture_compression_FXT1
  (neither AMD nor NVIDIA support this format, so while we could add it, I question its value...)
• GL_APPLE_object_purgeable

And here is the list of new features on iris (not supported by i965):

• OpenGL 4.5 compatibility profile
• GL_AMD_pinned_memory
• GL_ATI_fragment_shader (for Star Wars: Knights of the Old Republic in wine)

I haven't added it to features.txt because it's basically the same set.

Do you plan to make iris the default now that 19.3 is branched?

Kayden Thank you for your quick and informative answer!
