Hi Avadh,
Thank you very much for this release. Are there any plans on integrating the latest version of Qemu 0.14 with Marss? I've noticed a bug in Qemu whereby increasing the simulated memory size causes a significant slowdown in simulation speed and it affects Qemu 0.12.5 and possibly even 0.13x. I tested Qemu 0.14 and the issue has been fixed but I'm not sure which patch is responsible for this. I started a thread on the Qemu forum a couple of weeks back about this issue but since the bug is fixed, I doubt we'll get much feedback. Again, this may not be that big of an issue for Marss, since the ptlsim portion is the bottleneck when we start a detailed simulation, however it will affect how long it takes for just Qemu (in its native mode) to reach the point of interest.

Because of your support we have found many bugs and fixed them. I am glad to announce version 0.1.2 release of Marss with major changes listed below. Changes in 0.1.2: - Bug fixes in statistics collections - Bug fix in Simple Cache Controller related to ‘memory_op_update’ - Added support for ‘POP SEG_REG’ instruction [from Jarnau] - Fix error print when running with >3.5GB of RAM size [from Paul] - Bug fix in ‘ptlstats’ in using ‘-subtract’ option - Added option to execute user specified command after simulation completes [from Paul] - Bug fix in cpuController, attached callback function to queueAccess_ signal - Improvded code readability in cache code by replacing signal-attachment code with macro You can download the archive from here: https://github.com/avadhpatel/marss/tarball/0.1.2 Thanks, CAPS Group at SUNY Binghamton
