Allow EGL 1.5 implementations without GL_KHR_robustness #480

Open rmader opened 2 months ago

rmader commented 2 months ago

Driver may want to expose a minimal implementation of EGL_EXT_create_context_robustness - i.e. a dummy implementation without corresponding GL_KHR_robustness support - in order to support EGL 1.5.

When requesting a context with EGL_CONTEXT_OPENGL_ROBUST_ACCESS_EXT -> EGL_TRUE on such a driver, it has to create a EGL_BAD_CONFIG error - and unfortunately there's no way to check for GL_KHR_robustness in advance.

Thus handle that case gracefully.

This should allow Mesa to expose 1.5 support for all drivers on all hardware generations.

Specifically, this still allows querying of device reset status, without robust buffer access guarantees.

There are a few more places that need to be covered.

Nevermind and sorry for the noise - there were just some more issues in Mesa making tests fail.
