1 | .. _Sparc32-System-emulator: |
2 | ||
3 | Sparc32 System emulator | |
4 | ----------------------- | |
5 | ||
6 | Use the executable ``qemu-system-sparc`` to simulate the following Sun4m | |
7 | architecture 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 | ||
27 | The emulation is somewhat complete. SMP up to 16 CPUs is supported, but | |
28 | Linux limits the number of usable CPUs to 4. | |

30 | The list of available CPUs can be viewed by starting QEMU with ``-cpu help``. |
31 | Optional boolean features can be added with a "+" in front of the feature name, | |
32 | or disabled with a "-" in front of the name, for example | |
33 | ``-cpu TI-SuperSparc-II,+float128``. | |

35 | QEMU 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, | |
6b90a4cd | 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 | ||
54 | The number of peripherals is fixed in the architecture. Maximum memory | |
55 | size depends on the machine type, for SS-5 it is 256MB and for others | |
56 | 2047MB. | |
57 | ||
58 | Since version 0.8.2, QEMU uses OpenBIOS https://www.openbios.org/. | |
59 | OpenBIOS is a free (GPL v2) portable firmware implementation. The goal | |
60 | is to implement a 100% IEEE 1275-1994 (referred to as Open Firmware) | |
61 | compliant firmware. | |

63 | Please note that currently older Solaris kernels don't work; this is probably |
64 | due to interface issues between OpenBIOS and Solaris. |
