| 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, |
| :ref:`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. |
