Some users of KVM implement the UEFI variable store through a paravirtual device that does not require the "SMM lockbox" component of edk2, and would like to compile out system management mode. In preparation for that, move the SMM exit code out of emulate.c and into a new file. The code is still written as a series of invocations of the emulator callbacks, but the two exiting_smm and leave_smm callbacks are merged into one, and all the code from em_rsm is now part of the callback. This removes all knowledge of the format of the SMM save state area from the emulator. Further patches will clean up the code and invoke KVM's own functions to access control registers, descriptor caches, etc. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Maxim Levitsky <mlevitsk@redhat.com> Message-Id: <20220929172016.319443-4-pbonzini@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
