adding eu_total is enough, we can use the following if ... else statement later if (intel->eu_total > 0) { ... } else { ... } It avoids setting the number of thread to 0 (although it is unlikely) as well. > > const struct intel_device_info *device_info; > }; _______________________________________________ Libva mailing list Libva@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libva
