Hi Harsh, UST is not a stable library interface. It has not settled down yet, there are discussions about the library API on the project's mailing list. Therefore I'm not actively worrying about keeping it working. If you wish to send patches, please consider using <ust/version.h> to identify the version of the library you are adding support for with appropriate #ifdefs. Hopefully they will settle on a stable API soon and we can commit permanently working patches to QEMU. I also encourage you to keep in touch with the upstream community because they are active and friendly. Perhaps they can help you get it working. Stefan
