Hi, all
I have some questions about TK1 VM. I want to save the execution status of
the TK1 VM. First, I stop the VM, then I use the function,
seL4_TCB_ReadRegisters()
to read the VM's registers into a buffer.

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
