@node Sparc64 System emulator
@section Sparc64 System emulator
Use the executable @file{qemu-system-sparc64} to simulate a Sun4u
(UltraSPARC PC-like machine), Sun4v (T1 PC-like machine), or generic
Niagara (T1) machine. The Sun4u emulator is mostly complete, being
able to run Linux, NetBSD and OpenBSD in headless (-nographic) mode. The
Sun4v emulator is still a work in progress.
The Niagara T1 emulator makes use of firmware and OS binaries supplied in the S10image/ directory
of the OpenSPARC T1 project @url{http://download.oracle.com/technetwork/systems/opensparc/OpenSPARCT1_Arch.1.5.tar.bz2}
and is able to boot the disk.s10hw2 Solaris image.
@example
qemu-system-sparc64 -M niagara -L /path-to/S10image/ \
-nographic -m 256 \
-drive if=pflash,readonly=on,file=/S10image/disk.s10hw2
@end example
QEMU emulates the following peripherals:
@itemize @minus
@item
UltraSparc IIi APB PCI Bridge
@item
PCI VGA compatible card with VESA Bochs Extensions
@item
PS/2 mouse and keyboard
@item
Non Volatile RAM M48T59
@item
PC-compatible serial ports
@item
2 PCI IDE interfaces with hard disk and CD-ROM support
@item
Floppy disk
@end itemize
@c man begin OPTIONS
The following options are specific to the Sparc64 emulation:
@table @option
@item -prom-env @var{string}
Set OpenBIOS variables in NVRAM, for example:
@example
qemu-system-sparc64 -prom-env 'auto-boot?=false'
@end example
@item -M [sun4u|sun4v|niagara]
Set the emulated machine type. The default is sun4u.
@end table
@c man end
