The bug here is that the DRI context "flags" are intended to alias the GLX context flag values, and they don't, DRI's no-error flag is GLX's reset-isolation flag. GLX (and EGL!) treat no-error as a context attribute, and reset isolation predates Mesa's no-error implementation by several years. The GL_KHR_no_error spec does describe it as a "context flag", though, so maybe that's why we do it as a (DRI) context flag. In order to unalias these we need a new contract with the loader. We remove the old __DRI_NO_ERROR extension, and add a new __DRI_RENDERER_HAS_CONTEXT_NO_ERROR value to query. Loaders can key on that to know to pass no-error-ness through as a context attribute, matching the GLX/EGL calling convention. We go ahead and define __DRI_CTX_FLAG_RESET_ISOLATION as well, and update the drivers to refuse it since we don't support it yet. This means mismatched drivers/loaders will not be able to create no-error contexts. Too bad. If you want performance that badly you can build both things at once.
