1.. _Sparc32-System-emulator: 2 3Sparc32 System emulator 4----------------------- 5 6Use the executable ``qemu-system-sparc`` to simulate the following Sun4m 7architecture machines: 8 9- SPARCstation 4 10 11- SPARCstation 5 12 13- SPARCstation 10 14 15- SPARCstation 20 16 17- SPARCserver 600MP 18 19- SPARCstation LX 20 21- SPARCstation Voyager 22 23- SPARCclassic 24 25- SPARCbook 26 27The emulation is somewhat complete. SMP up to 16 CPUs is supported, but 28Linux limits the number of usable CPUs to 4. 29 30The list of available CPUs can be viewed by starting QEMU with ``-cpu help``. 31Optional boolean features can be added with a "+" in front of the feature name, 32or disabled with a "-" in front of the name, for example 33``-cpu TI-SuperSparc-II,+float128``. 34 35QEMU emulates the following sun4m peripherals: 36 37- IOMMU 38 39- TCX or cgthree Frame buffer 40 41- Lance (Am7990) Ethernet 42 43- Non Volatile RAM M48T02/M48T08 44 45- Slave I/O: timers, interrupt controllers, Zilog serial ports, 46 :ref:`keyboard` and power/reset logic 47 48- ESP SCSI controller with hard disk and CD-ROM support 49 50- Floppy drive (not on SS-600MP) 51 52- CS4231 sound device (only on SS-5, not working yet) 53 54The number of peripherals is fixed in the architecture. Maximum memory 55size depends on the machine type, for SS-5 it is 256MB and for others 562047MB. 57 58Since version 0.8.2, QEMU uses OpenBIOS https://www.openbios.org/. 59OpenBIOS is a free (GPL v2) portable firmware implementation. The goal 60is to implement a 100% IEEE 1275-1994 (referred to as Open Firmware) 61compliant firmware. 62 63Please note that currently older Solaris kernels don't work; this is probably 64due to interface issues between OpenBIOS and Solaris. 65
