I'm not super-enthusiastic about this simply because it breaks the current arrangement we have where everything in about/ is relatively brief meta-information about QEMU: build platforms, deprecated and removed features, license. On the other hand I don't have an obvious better idea to hand for where to put it. > Signed-off-by: Alex Bennée <alex.bennee@linaro.org> > --- > docs/about/emulation.rst | 103 ++++++++++++++++++++++++++++++++++ > docs/about/index.rst | 1 + > docs/devel/tcg-plugins.rst | 2 + > docs/system/arm/emulation.rst | 2 + > 4 files changed, 108 insertions(+) > create mode 100644 docs/about/emulation.rst > > diff --git a/docs/about/emulation.rst b/docs/about/emulation.rst > new file mode 100644 > index 0000000000..d919175b5e > --- /dev/null > +++ b/docs/about/emulation.rst > @@ -0,0 +1,103 @@ > +Emulation > +========= > + > +QEMU's Tiny Code Generator (TCG) gives it the ability to emulate a > +number of CPU architectures on any supported platform.
