[Mesa-dev] [PATCH v3] mesa: Enable GL_KHR_robustness

Kristian Høgsberg krh at bitplanet.net
Wed May 25 02:41:01 UTC 2016


From: Kristian Høgsberg Kristensen <krh at bitplanet.net>

GL_KHR_robustness adds the GL_CONTEXT_LOST error and five new entry
points that we already implement.  This patch adds a new dispatch
table that returns GL_CONTEXT_LOST from all entry points and
implements the GL_LOSE_CONTEXT_ON_RESET by setting that table when we
learn that we've lost the context.

With the GL_CONTEXT_LOST reporting in place and dispatch for the new
entry points we can turn on GL_KHR_robustness.

v3: Only advertise for GLES2.0+, fix typo and dispatch_sanity
issue. Reword commit message to say we're enabling GL_KHR_robustness,
not just turning on GL_CONTEXT_LOST.
