Hi Peng,
1. TLB status is irrelevant 2. Contents of registers from seL4_UserContext are always just literally what that thread had in its registers, no translation in any direction is done by the kernel

Here are my questions: 1. Before I call the function, seL4_TCB_ReadRegisters(), do I need to flush TLB of CPU? If so, where is the library I need to check for this function? 2. The register values in the structure, seL4_UserContext, are VMM's physical addresses or virtual addresses?
Best wishes
Peng
