About NetBSD/sparc64

NetBSD/sparc64 is a NetBSD port to Sun's 64-bit UltraSPARC machines. The first binary release for sparc64 was NetBSD 1.5. NetBSD/sparc64 supports many systems, including Sbus-based UltraSPARC systems and PCI-based UltraSPARC systems using UltraSPARC I, II, IIi, and IIe CPU types.

NetBSD/sparc64 supports both 32-bit and 64-bit kernels. A 32-bit kernel runs all NetBSD/sparc binaries. A 64-bit kernel runs 64-bit binaries, and has support for running most 32-bit binaries as well, with the exception of some low level kernel groveling tools. Additionally, NetBSD/sparc64 is able to run Solaris 64 and 32 bit binaries with emulation. See compat_netbsd32(8), compat_solaris(8) and the pkgsrc package emulators/netbsd32_compat16.

Martin Husemann and Andrey Petrov are the maintainers for NetBSD/sparc64.

2008-03-15: SMP mostly working
Takeshi Nakayama has committed fixes to -current that make SMP actually work (his machine has survived a -j 4 run). See his mail for the announcement.

Havard Eidnes has uploaded binary packages for NetBSD/sparc64 4.0_BETA2 from the pkgsrc-2007Q1 branch to For more details, please read his announcement.

2006-11-24: Binary packages for pkgsrc-2006Q3
Julian Coleman has uploaded binary packages for NetBSD/sparc64 3.0 from the pkgsrc-2006Q3 branch to
2006-10-24: Stable again
The stability problems caused by the SMP changes (see below) have been solved. SMP is still not working, unfortunately.
2006-10-07: SMP progress - but not success yet
Matthew Green and Martin Husemann have started to merge quite old changes originally written by Andrey Petrov into current. Matthew Green also added ddb support for SMP kernels on sparc64. Unfortunately SMP kernels do not work yet, and it seems that some of the changes had side effects even for uniprocessor kernels. One example of this is probably PR 34741. This means that -current is not as stable as you might expect for sparc64, but that there is progress on SMP. Stay tuned.

2006-03-02: Support for Atheros wlan devices
Atheros wlan devices require a binary-only HAL, linked into the kernel with the driver proper. After David Young imported a new HAL, a version for NetBSD/sparc64 is now available, tested, and known to work.
2006-01-30: New bootloader required
Dennis Chernoivanov recently reworked the bootloader/kernel protocol. This means that you need to install a new bootloader before updating a kernel. Instructions can be found here. The new bootloader will, of course, boot older kernels as well.
