Subject: Allow RBUG to start blocked
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2883e3c0b5eafcc871775e0c3dbdf97ac6f35e15;p=mesa.git

Allow RBUG to start blocked

It is sometimes useful to examine the first frame or and early frame of a
quickly executing and non-repeating application, this chain introduces a new
environment variable that is checked when creating contexts.  If
GALLIUM_RBUG_START_BLOCKED is set, then each context that is created is started
in a blocked state.  This allows time to connect rbug before anything is
rendered in the context.
