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,
|
|
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.
