egl extension EGL_KHR_fence_sync on IMX7ULP

[Nico_H]

Hello,

does anyone see on the IMX7ULP other egl extensions than EGL_EXT_client_extensions or EGL_EXT_platform_base?

According to the i.MX Graphics User's Guide there should be others than these two.

Especially I want to use the EGL_KHR_fence_sync because the vsync on eglSwapBuffers does not work, even if I set eglSwapInterval to 1.

Best regards,

Nico

eglSwapInterval is working by using 'export FB_MULTI_BUFFER=2'

Hello Nico_H,

GL_OES_EGL_sync is only available on GLES 1.1, other GLES APIs will report it as non supported

EGL_KHR_fence_sync is supported.Just There is no reference at all for VG_KHR_EGL_sync.

Also eglSwapInterval is not supported on current versions
