Thanks Tapani for the updates!
I tried following:
diff --git a/src/mesa/drivers/dri/i965/intel_batchbuffer.c
b/src/mesa/drivers/dri/i965/intel_batchbuffer.c
index df999ffeb1d0..325f28b35e60 100644
--- a/src/mesa/drivers/dri/i965/intel_batchbuffer.c
+++ b/src/mesa/drivers/dri/i965/intel_batchbuffer.c
@@ -823,7 +823,7 @@ submit_batch(struct brw_context *brw, int in_fence_fd, int
*out_fence_fd)
if (ret != 0) {
fprintf(stderr, "i965: Failed to submit batchbuffer: %s\n",
strerror(-ret));
- exit(1);
+ //exit(1);
}
return ret;
If we don't exit, after GPU hang, it will continue the rest test. But the first
part test is still black.</pre>
