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 30QEMU emulates the following sun4m peripherals: 31 32- IOMMU 33 34- TCX or cgthree Frame buffer 35 36- Lance (Am7990) Ethernet 37 38- Non Volatile RAM M48T02/M48T08 39 40- Slave I/O: timers, interrupt controllers, Zilog serial ports, 41 keyboard and power/reset logic 42 43- ESP SCSI controller with hard disk and CD-ROM support 44 45- Floppy drive (not on SS-600MP) 46 47- CS4231 sound device (only on SS-5, not working yet) 48 49The number of peripherals is fixed in the architecture. Maximum memory 50size depends on the machine type, for SS-5 it is 256MB and for others 512047MB. 52 53Since version 0.8.2, QEMU uses OpenBIOS https://www.openbios.org/. 54OpenBIOS is a free (GPL v2) portable firmware implementation. The goal 55is to implement a 100% IEEE 1275-1994 (referred to as Open Firmware) 56compliant firmware. 57 58A sample Linux 2.6 series kernel and ram disk image are available on the 59QEMU web site. There are still issues with NetBSD and OpenBSD, but most 60kernel versions work. Please note that currently older Solaris kernels 61don't work probably due to interface issues between OpenBIOS and 62Solaris.
