Documentation/Platforms/SPARC
Welcome to the SPARC homepage. This page contains news and resources for users looking to emulate sun4m or sun4u systems under QEMU.
Status
The table below gives the status of the SPARC machines available in QEMU and is correct as of QEMU 2.10:
| Machine | Status |
|---|---|
| sun4m | Complete, supported |
| sun4u | Beta, supported |
| sun4v | Incomplete, unsupported |
| niagara | Complete, supported |
Installation
Debian/RedHat packages
Users should install the qemu-system-sparc package in order the use the SPARC system emulators provided by their distribution.
Building from source
By default QEMU will build both the qemu-system-sparc and qemu-system-sparc64 system emulators unless QEMU has been configured with a specific target list. If you are looking to build just the SPARC system emulators from source yourself, then pass the options --target-list="sparc-softmmu sparc64-softmmu" to QEMU's configure script.
Compatibility
The tables below show the results of testing various SPARC and SPARC64 guests in QEMU in the latest release (2.10):

| sun4u | FreeBSD 10.3 | FreeBSD-10.3-RELEASE-sparc64-disc1.iso | Working | Requires -nographic in order to boot. Due to a restriction in reading the psycho device properties, kernels < 10.3 panic on boot. A fix for this has been merged into both 10.3 and the up-and-coming 11.0 release. |
| sun4u | HelenOS 0.7.0 | HelenOS-0.7.0-sparc64-ultra.iso | Working | Requires -nographic -prom-env boot-args="console=devices/\hw\pci0\00:03.0\com1\a" to boot. |

Artyom has contributed several patches to improve SPARC emulation under QEMU and has lot of related information, particularly for users trying to run Solaris images under emulation. Some of the content is a little out of date (OpenBIOS should work with practically all Solaris versions now) but the FAQ is very helpful indeed.

Torbjörn uses QEMU to build and test the GNU GMP libraries on various platforms, and while the information is a little out of date, there are some useful configurations listed on the page.

Olivier Danet has implemented a sun4m machine in an FPGA which is capable of booting many SPARC32 OSs, and as a consequence has provided several patches to fix bugs in SPARC32 emulation (and also OpenBIOS)

OpenBIOS is the Open Firmware implementation used by QEMU for SPARC32/SPARC64 (and indeed also for PPC)
