Hi, Avadh, Thanks.
I think the patch works. The assertion does not happen after patching the code. But when my 2-threads application running on marss, it seems only one core run the application, the other core always stuck in the kernel mode. In the source code of the 2 thread application, I set the affinity to each core by using pthread. It can run well on Qemu and get the correct result. Do you have any idea about this problem? Thank you.
