Phoronix: EGL 1.5 Released, Includes Wayland Platform Extensions

The latest industry standard unveiled today at the Game Developer's Conference in San Francisco is the EGL 1.5 specification from the Khronos Group...

"EGL 1.5 is a significant step to enabling access to proven and needed functionality across a wide variety of platforms including Android, X Windows and Ubuntu-based systems.”

https://www.khronos.org/news/press/k...-specification

Damn and I was hoping for Linux support.

So this is part of 1.5 now?

The new EGL Platform extensions added to version 1.5 of the Khronos Group specification is for Android, GBM, Wayland, and X11. These extensions define how each platform/OS interact with EGL to allow the single EGL implementation to support the different windowing systems.

So no Mir expected.

Is anyone else bothered that the specification calls for (insert here)-server specific parts?

EGL is going to end up just like GXL, where its so (insert here)-server specific that it'll eventually have to be abandoned for (insert letter here)XL in the future in order to leave behind old cruft and lock-ins...

Or am I crazy to think this?

I think you're crazy. If OpenGL is any indication, they won't ever abandon it and just continue supporting the cruft.

Which parts are you talking about?

EGL can be used by the X.Org Server and is supported by the various graphics drivers, most recently with NVIDIA's binary Linux driver.

Your statement got me intrigued so I went to the nvidia webpage to see their release notes for the latest driver, which happens to be the 334.16 Beta. Is this what you're referencing Michael?

Added 64-bit EGL and OpenGL ES libraries to 64-bit driver prackages.

Does this mean that it is possible to run Weston with nvidia drivers now?
Any insights are much appreciated.

No. Nvidia doesn't support the EGL Wayland platform.

When you start it with the X11 Backend it does the NVIDIA EGL/GLES2 implementation. You can start weston on X11 with any card, but it will fallback to using LLVMPipe so basically runs on the CPU.

You can't do a weston-launch from tty to use the drm-backend, since weston requires KMS for modesetting. Would not be surprised to find EGL 1.5 support in a beta driver a few months from now.
