1 .. _Sparc32-System-emulator:
3 Sparc32 System emulator
4 -----------------------
6 Use the executable ``qemu-system-sparc`` to simulate the following Sun4m
21 - SPARCstation Voyager
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:
39 - TCX or cgthree Frame buffer
41 - Lance (Am7990) Ethernet
43 - Non Volatile RAM M48T02/M48T08
45 - Slave I/O: timers, interrupt controllers, Zilog serial ports,
46 :ref:`keyboard` and power/reset logic
48 - ESP SCSI controller with hard disk and CD-ROM support
50 - Floppy drive (not on SS-600MP)
52 - CS4231 sound device (only on SS-5, not working yet)
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
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)
63 Please note that currently older Solaris kernels don't work; this is probably
64 due to interface issues between OpenBIOS and Solaris.
