I view the man page output using "man -l man7/sgx.7" and when I do so
the above line is unbalanced: "enclave" and (unexpectedly) the comma are
underlined and the line is displayed with a single instance of a double
quote: enclave = open("/dev/sgx_enclave, O_RDWR);
After some trial and error, and looking at symlink.7, this seems to
fix it:
-.IB enclave " = open(""/dev/sgx_enclave", " O_RDWR);"
+.IB enclave " = open(""/dev/sgx_enclave"", O_RDWR);"
Does this fix for you?
Yes, thank you. When looking at your updated patch I see that only
enclave is underlined and the quotes are matching.

This does not document the SGX_IOC_VEPC_REMOVE ioctl that was added in
v5.16. How do you envision additions to this page as new features are
added to the Linux support of SGX?
I started this before any of KVM stuff was in upstream. It'd be better
to get the basic ioctl's done first. I cannot really give estimate for
vepc at this point.
SGX_IOC_VEPC_REMOVE_ALL can be found in v5.16.
For future features (e.g. SGX2), the expectation is that the feature is
supported by an associated man page update.
ok, thank you.
