Re: Indy and indigo2 emulation in MESS (WIP)

That would be R4000 architecture, not the R3000 he says he's having problems with. Yes, I know, I suggested it not because of R3000 support, but because of a better timing accuracy. While it's nice to be able to have a "run as fast as you can" mode (like QEMU does), it's even more importa...

Re: Indy and indigo2 emulation in MESS (WIP)

I'm currently using QEMU for MIPS emulation, which has some limitations, at least for the R3k, which makes emulating the PI impractical (no R3k TLB support). Did you try the cycle-accurate MIPS emulator from the CEN64 project? I believe that if its CPU emulation isn't 100% complete, it will be arou...

SGI is listed as with current support too: https://www.openbsd.org/sgi.html Hence my question about if anybody tried the just recently enabled clang in OpenBSD.

Re: clang 64-bit MIPS enabled in OpenBSD

It would have to support the o32/n32/n64 ABI, output big endian code and a number of other things I'm not sure if it's ready to do or not. AFAIK, OpenBSD runs only as 64bit on SGIs. Not sure about the ABI. Theoretically, the ABI could be totally different to IRIX, unless there's some constraint imp...

clang 64-bit MIPS enabled in OpenBSD

I've just found a commit in the OpenBSD tree, related to enabling MIPS support in clang. However, IIRC, clang wasn't yet ready for outputting MIPS3 nor MIPS4 code. Has that changed? If affirmative, I consider this a great achievement, as it would mean clang would run on SGI hardware... Anybody has a...

Re: Some concept screenshots I made a while ago

After quite a few years using OS X (after SGI decision to drop IRIX), I realize NeXTSTEP had many things that sweetly solved the (very few) things that weren't convenient in IRIX. For example: -app-bundles (turning it unnecessary to install applications... they're seen as an icon in the desktop, but...

Re: HP(e) buys SGI for US$275MM

I do agree modern computing is rather boring. You don't see the groundbreaking innovations anymore. It seems the days of expensive, exotic systems, with groundbreaking and mind blowing performance - have come to an end. The technological progress has largely stagnated and it's a terrible shame. I d...

Re: HP(e) buys SGI for US$275MM

Is it possible to know who owns IRIX in this moment? I'm serious about this question, the chances in any open source possibility could depend on that question. Is it possible to answer that question with legal certainty?

Re: HP(e) buys SGI for US$275MM

The one thing I still ponder is the fact that no one is really making computer animation workstations for high end computer generated effects for film and television anymore. [...] I don't know. Just brainstorming. I already know that everyone says CGI is a niche market but you'd be surprised how m...

Re: HP(e) buys SGI for US$275MM

I think the simplest way to get a somewhat limited IRIX 6.5 up and running under emulation quickly on x86/Linux would be to use the Indy port of IRIX as a starting point to port IRIX 6.5 to SimOS/MIPS. I did OS development using SimOS/MIPS a long time ago- its probably a few weeks work to port to t...

Re: HP(e) buys SGI for US$275MM

There's a list of what copyrighted/trademarked code there is in IRIX in the IRIX installation instructions. Avid has a copy of the 6.5.28 instructions on their website, the list is on pages 2 and 3: http://download.autodesk.com/us/systemdocs/pdf/irix6528_installation_guide.pdf I'm not sure of that ...

Re: HP(e) buys SGI for US$275MM

If the Irix source code ever does become open source, it would require a monumental effort to port it to x86, I'm not sure our hearty band of merrymakers has the required motivation. It would probably be a lot easier to port it to a modern MIPS microprocessor, but does anyone make MIPS-based workst...

Re: HP(e) buys SGI for US$275MM

It would be good if they open sourced it, and who knows, maybe the HPE purchase will shuffle some things around and put people who want to release IRIX code in more power somehow, but as said above it would I think be a relatively large undertaking to clean out the cross-licensed stuff and release ...

Original Price for RE and IR pipes?

For a gfx hardware history table I'm composing, I'd wish to have the approximate original price for a RE pipe (from 1993) and for an IR pipe (from 1996). Looking at the prices from the periodic tables, which are for RE/IR complete systems, and deducing an approximate base system cost, I came to the ...

Re: HP(e) buys SGI for US$275MM

There is too much encumbered code with IRIX that is cross-licensed from multiple sources. Open Sourcing it will not be an option. However, making it freely available for download and hobbyist usage (as-is with no support) might be an option. With a little effort, it should be possible to isolate pa...
