[ This was sent to all the lists at once, that didn't work for some reason, so I'm sending it one list at a time to make it work. ]
Are you tired of wondering what the true performance capabilities of your UltraSparc system are?
Are you tired of the endless promises from SunSoft as to when they will provide you with a true 64-bit userland under Solaris?
Are you tired of not being able to find out what is going on "under the hood" of the OS you currently run on your UltraSparc systems?
Yes? Well then wake up sleepy head, UltraPenguin-1.0 is here!
( A condensed version of this announcement is readable via http://sunsite.mff.cuni.cz/linux/ultrapenguin-1.0/ as well)
UltraPenguin-1.0
NEW BRUNSWICK, PRAGUE. Jul, 12th, 1997. The UltraLinux team proudly announces UltraPenguin 1.0, first publicly available distribution of Linux for UltraSPARC I and II processor based workstations. Some lower end EnterPrise server machines are supported as well in uni-processor mode. See below.
This distribution is based on Red Hat Linux, version 4.2 for sparc.
*DISCLAIMER*: Although this is based upon a RedHat Linux release, RedHat does not support this. They will not provide support for the UltraPenguin-1.0 distribution. It is our hack which we put together so that people can be provided with a full UltraLinux system early. Please do not bother RedHat about problems you encounter with this release, thank you.
UltraLinux is a fast 64bit free operating system, which supports up to 1TB of physical and another 1TB of IO memory, fully supports Linux/Sparc 32bit binaries plus will soon support 64bit UltraLinux ELF binaries. It uses the Visual Instruction Set for high bandwidth operations, even older 32-bit applications take advantage of this increased performance if they are dynamically linked.
The 64-bit userland for UltraPenguin is half done, developers have initial statically linked ELF 64-bit binaries working. We will announce seperately the availability of this so others can experiment with it and help us out, so please be patient.
Where can I get it?
ULTRAPENGUIN 1.0 distribution is available at least from the following sites:
ftp://sunsite.mff.cuni.cz/OS/Linux/Sparc/ultrapenguin-1.0 ftp://vger.rutgers.edu/pub/linux/Sparc/ultrapenguin-1.0
But surely it will reach all the sites which mirror these two very soon.
What UltraSparc machines are currently supported?
Ultra 1 desktop systems Ultra 2 desktop and some server systems
which have a TurboGX (cgsix) framebuffer.
Creator and Creator3D machines are not yet supported, unless you put a supported framebuffer into one of the sbus slots. Creator support is now actively being developed.
Ultra 2 low end servers are supported in uni-processor mode. For example, Ultra EnterPrise 1 and Ultra EnterPrise 2 servers can be expected to work. Higher end EnterPrise server machines such as the 3000, 4000, 5000, 6000, and 10000, all of which use the Gigaplane bus, are not supported yet.
If you are interested in seeing UltraPenguin supported on the higher end server machines, you are encouraged to make an effort to help Jakub or David obtain such a system so that the support can be written.
(David leaves for SGI in mid September, and thus will no be able to contribute as heavily, if at all, on the necessary work, so if you can assist with this, do it soon!)
We realize that many will want to install and use UltraPenguin via a serial console. RedHat fully supports this in their installation mechanism, *however* we have been so busy working on getting UltraPenguin to a releasable state that we have not had time to test and fix any problems with serial console in the kernel. In fact we have not even tried to use it for some time. Please be patient, and we will work on making it work and giving it a good testing. Such updates will be announced here and on the usual Linux/Sparc mailing lists, so it will be hard to miss when it happens. 8-)
You might want to ask why do I need Linux on my Ultra? - here is a couple of reasons why you shouldn't miss this:
It is free (you have full source code for kernel and most of the userland programs (with the exception of commercial binary only programs))
It is fast (it tries to get most of the wonderful features of the SPARC v9 and the UltraSPARC chip - the speed increase from running the same program on Solaris 2.5.1 may be really big - see following lmbench numbers
It is 64bit - no need to limit yourself to 4G of virtual memory. Also, your programs can make use of full 64bit registers
It has virtual consoles, unlike Solaris, where the console is nearly unusable and whoever wants to actually do something must run X Window immediately
It runs nearly all SunOS binaries and some Solaris binaries (more progress with Solaris binary support will appear soon, especially now that we have completed most of the Ultra port work, but see below how you can make this happen faster!)
How fast is it? Well, you are invited to go take a look at some lmbench numbers we've been collecting during the porting work:
http://sunsite.mff.cuni.cz/linux/ultrapenguin-1.0/lmbench.txt
There is still a lot to do! But here is how _you_ can help to make it happen more quickly.
Free software projects, such as the UltraPenguin port, base their success mostly upon the help of various individuals on the net. The more of these people we have for the project, the more successful it will be and the more quickly progress will be made.
This is why we are asking for people who have spare time to help us complete our goal of having a more complete UltraPenguin system. Here is a brief list of projects on which you may be able to help out:
1) 64-bit userland
Although half or mostly complete, much work still needs to be done. Jakub and myself will be working hard on adding shared library support to what we have already. But we will certainly need people to test compiling many packages and finding+reporting bugs that they find when doing that.
Some time next week we will put up the current work which has been completed so far, so people can "play" with it and perhaps decide if they would like to help us finish it.
2) New platforms
The code necessary to support just about any current SBUS based Ultra desktop or server has been written. What does not exist is the minimal code necessary to support Sun's higher end Enterprise server systems. This work essentially requires that either Jakub or David get some kind of direct access to such systems. So if you are in a position to make this a reality for us, you are highly encouraged to do so and to contact David and Jakub.
David will be working on SMP support starting next week, this work should be done quickly because he does have a dual processor system on his desk now.
As for Ultra/AX PCI based machines, we have someone working on these systems, but having more of us working on it cannot hurt and can only make it happen faster. So if you can donate machine and documentation loaners, please do so!
3) Solaris binary compatibility
Solaris binary compatibility is half way done via the iBCS2 module and some programs work, but a lot of work is still needed. David, Jakub and Miguel are now really busy with other hacks, so if you'd like to help with this, we'd be very thankful.
4) SunOS free ld.so
So that people don't have to buy SunOS just so that they can run Netscape on their UltraLinux and SparcLinux boxes, we need someone to write a free ld.so for SunOS shared binaries. Some work in this area has already been done, but not much yet.
5) Framebuffer support
We're looking for framebuffer hackers as well, especially for people who will write support for double buffering for TurboGX and full support for the Creator and Creator3D framebuffers in X11R6.3. You might also work on enhancing existing kernel framebuffer drivers.
Also, Dirk Hohndale of the XFREE86 project has expressed interest in merging all of our Sun frame buffer support into the Xfree86 sources. In this way, one unified source base for X will exist for all Linux platforms. This would not be very complex work, but would require a bit of someone's time. If you would like to help organize and work on this please contact us soon.
6) ATM
Jakub has two sbus ATM cards, one from Cisco and one SunATM 1.0 and there is a generic support for ATM layer for Linux already, but really has no time to play with the cards without single line of documentation, so if you could get us some documentation on these monsters and/or write the support yourself, you'd help a lot.
7) GCC
There is still a lot of work in making GCC produce more optimized code for the UltraSPARC. Also, David started a project for new sparc support in gcc, so that one single compiler will be able to produce 32bit sparc code, 32bit code enhanced by the v9 instructions and full 64bit v9 and v9a code. You can help with this as well, just ask...
CREDITS and Thank You's
Although Jakub and David have done the majority if not all of the 64-bit port of the kernel, others have helped in substantial ways and we'd like to make mention of them here:
Thanks for Linus "Pinhead" Torvalds for constructing an operating system worth porting to such nice hardware in the first place.
Thanks to John Gilmore, the CAIP Research Center at Rutgers University, and Charles University in Prague for providing us with the hardware on which to perform the port. Without these donations absolutely nothing would have happened and UltraPenguin-1.0 would have been a dream at best.
Thanks to David Sitsky for the initial 32-bit Ultra port, this work proved that such a port was possible at all and provided the basis for some of the things we did in the 64-bit kernel.
Doug Evans and the rest of the GCC development team for a true 64-bit Sparc/V9 port of the compiler and utilities so that we could have the tools necessary to actually develop UltraPenguin-1.0
Richard Henderson for doing all of the GNU libc porting work and testing so far for the sparc64 platform. Jakub and David would have much more work to do here had Richard not done what he has thus far. His contribution is immeasurable.
Thanks to Larry McVoy, for writing the LMBENCH benchmark suite, so that we could perform our initial performnce work on the UltraLinux kernel.
Since the sparc64 kernel is using many of the existing drivers from the sparc32 and also other parts of the code from that code, the other Linux/Sparc hackers must be mentioned. This includes the following people: Miguel De Icaza, Eddie C. Dost, Derrick J. Brashear, Thomas K. Dyas, Manish Vachharajani, and others too numerous to mention.
Extra special thanks to RedHat Software for providing the 32-bit Sparc release which we could base the UltraPenguin-1.0 distribution on. This has saved us an enormous amount of work.
Non-Thank You's
We initially considered listing here the people and organizations who over time, and still today, give us a hard time. However, we decided that this is bad manners for such a festive announcement.
These assholes know who they are anyways... 8-)
