docs/system: convert Texinfo documentation to rST Apart from targets.rst, which was written by hand, this is an automated conversion obtained with the following command: makeinfo --force -o - --docbook \ -D 'qemu_system_x86 QEMU_SYSTEM_X86_MACRO' \ -D 'qemu_system QEMU_SYSTEM_MACRO' \ $texi | pandoc -f docbook -t rst+smart | perl -e ' $/=undef; $_ = <>; s/^- − /- /gm; s/QEMU_SYSTEM_MACRO/|qemu_system|/g; s/QEMU_SYSTEM_X86_MACRO/|qemu_system_x86|/g; s/(?=::\n\n +\|qemu)/.. parsed-literal/g; s/:\n\n::$/::/gm; print' > $rst In addition, the following changes were made manually: - target-i386.rst and target-mips.rst: replace CPU model documentation with an include directive - monitor.rst: replace the command section with a comment - images.rst: add toctree - target-arm.rst: Replace use of :math: (which Sphinx complains about) with :sup:, and hide it behind |I2C| and |I2C| substitutions. Content that is not @included remains exclusive to qemu-doc.texi.

.. _direct_005flinux_005fboot:
Direct Linux Boot
-----------------
This section explains how to launch a Linux kernel inside QEMU without
having to make a full bootable image. It is very useful for fast Linux
kernel testing.
The syntax is:
.. parsed-literal::
|qemu_system| -kernel bzImage -hda rootdisk.img -append "root=/dev/hda"
Use ``-kernel`` to provide the Linux kernel image and ``-append`` to
give the kernel command line arguments. The ``-initrd`` option can be
used to provide an INITRD image.
If you do not need graphical output, you can disable it and redirect the
virtual serial port and the QEMU monitor to the console with the
``-nographic`` option. The typical command line is:
.. parsed-literal::
|qemu_system| -kernel bzImage -hda rootdisk.img \
-append "root=/dev/hda console=ttyS0" -nographic
Use Ctrl-a c to switch between the serial console and the monitor (see
:ref:`pcsys_005fkeys`).
