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.

.. _Sparc32-System-emulator:
Sparc32 System emulator
-----------------------
Use the executable ``qemu-system-sparc`` to simulate the following Sun4m
architecture machines:
- SPARCstation 4
- SPARCstation 5
- SPARCstation 10
- SPARCstation 20
- SPARCserver 600MP
- SPARCstation LX
- SPARCstation Voyager
- SPARCclassic
- SPARCbook
The emulation is somewhat complete. SMP up to 16 CPUs is supported, but
Linux limits the number of usable CPUs to 4.
QEMU emulates the following sun4m peripherals:
- IOMMU
- TCX or cgthree Frame buffer
- Lance (Am7990) Ethernet
- Non Volatile RAM M48T02/M48T08
- Slave I/O: timers, interrupt controllers, Zilog serial ports,
keyboard and power/reset logic
- ESP SCSI controller with hard disk and CD-ROM support
- Floppy drive (not on SS-600MP)
- CS4231 sound device (only on SS-5, not working yet)
The number of peripherals is fixed in the architecture. Maximum memory
size depends on the machine type, for SS-5 it is 256MB and for others
2047MB.
Since version 0.8.2, QEMU uses OpenBIOS https://www.openbios.org/.
OpenBIOS is a free (GPL v2) portable firmware implementation. The goal
is to implement a 100% IEEE 1275-1994 (referred to as Open Firmware)
compliant firmware.
A sample Linux 2.6 series kernel and ram disk image are available on the
QEMU web site. There are still issues with NetBSD and OpenBSD, but most
kernel versions work. Please note that currently older Solaris kernels
don't work probably due to interface issues between OpenBIOS and
Solaris.
