[Xen-devel] [PATCH v3 4/6] tools: Expose XSM Flask initial SIDs list to tools

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

By generating tools/include/xen-xsm/flask/flask.h using the same tool
as used during the hypervisor build.

Note that this is done regardless of whether XSM is enabled, since we
want the tools to be agnostic to whether or not XSM is enabled in the
hypervisor
