Hi,
I am beginner of UML. I have a question about how the system call
trap happens in UML in skas0 mode. Suppose a user application
within UML initialed a system call. How does UML track the
system call and is the host OS the one to actually handle the system
call?
Particularly, I found a file: arch/um/sys-i386/stub.S. Is the file used
for handling syscalls in user application? Can somebody explain the
process to me?
Thank you
Haifeng
