Description Chris Paulson-Ellis 2013-06-09 16:56:05 UTC 
If I try and run any EGL program using the egl_dri2 driver, I get errors about EGL_IMAGE. eg:

$ EGL_LOG_LEVEL=debug src/egl/opengl/eglinfo 
libEGL debug: Native platform type: x11 (build-time configuration)
libEGL debug: EGL search path is /usr/lib/egl
libEGL debug: added egl_dri2 to module array
libEGL debug: added egl_glx to module array
libEGL debug: DRI2: dlopen(/usr/lib/dri/nouveau_vieux_dri.so)
libEGL debug: DRI2: found extension `DRI_Core'
libEGL info: DRI2: found extension DRI_Core version 1
libEGL debug: DRI2: found extension `DRI_DRI2'
libEGL info: DRI2: found extension DRI_DRI2 version 3
libEGL debug: DRI2: found extension `DRI2_Flush'
libEGL info: DRI2: found extension DRI2_Flush version 3
libEGL debug: DRI2: found extension `DRI_TexBuffer'
libEGL info: DRI2: found extension DRI_TexBuffer version 2
libEGL debug: DRI2: found extension `DRI_CONFIG_QUERY'
libEGL fatal: DRI2: did not find extension DRI_IMAGE version 1

I'm running latest git kernel, drm, mesa, xf86-video-nouveau & mesa/demos. Everything else from Fedora 18. My card is an NV11 [GeForce2 Go].

Desktop GL works at least a little (glxgears works). I do have problems with slow rendering in some programs with the nouveau X driver which don't occur with the modesetting X driver (eg: rectangle selection animation in GIMP causes a big slow down), but the desktop is basically functional.

Ultimately, I'm trying to get wayland/weston working on my ancient hardware to see if it's a feasible proposition. Functioning EGL is the current hurdle.

Chris.

Hi Chris

The first advice in general would be to try the latest kernel/mesa from git, although in your case that would be useless

Surprisingly enough I was just checking over nouveau_vieux and how much effort it would be to bring it up-to speed with the dri/core changes introduced by Intel, don't get too excited though

With that said afaik no one is working on nouveau_vieux overall so it may be faster to give it a stab yourself. The intel driver may be a good start/reference point

Cheers
Emil

What happens if you drop

    &driImageDriverExtension.base,

into the nouveau_driver_extensions array? (right before the DRI2 extensions)

Er nm. The nouveau_screen_extensions also need to have it, and I don't think there's a generic implementation...
