MIPS Open "open" licence...
« on: May 11, 2019, 06:45:34 pm »
Some recent buzz about Wave Computing supposedly "open-sourcing" the venerable MIPS ISA, and how it would surely kill RISC-V in the egg, prompted me to investigate a bit, as this is an ISA I know quite well and rather like.

Well...
First you have to register in order to access anything.
The registration process insists on personal information and also contains a survey of what your intended uses are, and what you use currently.
Then you must agree to these terms :

MIPS Open™ Architecture License Agreement ver 1.0 (“Agreement”)

© 2019 MIPS Tech, LLC

THIS AGREEMENT CONSTITUTES A BINDING CONTRACT ON YOU AND GOVERNS YOUR USE OF THE MIPS OPEN DELIVERABLES.  By clicking “Accept” to this Agreement below, the person or entity so accepting (“You”) agree to be bound by this Agreement. If You are entering into this Agreement on behalf of a company, organization or other legal entity (an “Entity”), You are agreeing to this Agreement on behalf of that Entity and are representing to MIPS that You have the authority to bind such Entity to this Agreement, in which case the terms “You,” “Your” or a related capitalized term herein shall refer to such Entity. If You do not have such authority, or if You do not agree with this Agreement, You must not accept this Agreement and You do not have a license to use the MIPS Open Deliverables. An Entity does not include its subsidiaries or affiliates.  Each and every subsidiary or affiliate of such Entity must separately execute this Agreement in order to have access to and use the MIPS Open Deliverables.

The purpose of this Agreement is to establish the terms and conditions under which You may use and access the MIPS Open Deliverables as described herein and provided by MIPS Tech, LLC, a Delaware limited liability company (“MIPS”).

    Definitions:

(a)“MIPS Direct-Licensed Core” means any microprocessor core made generally available for license from MIPS or its affiliates or predecessors that was either (i) licensed by MIPS or its affiliate or predecessor, to You or Your affiliate, or (ii) developed by You or Your affiliate under rights licensed under a MIPS Architecture by MIPS or its affiliate or predecessor.

(b)“MIPS Architecture” means the RISC technology processor instruction set architecture (“ISA”) or any application specific extension (“ASE”) to such architecture, and any associated privileged resource architecture (“PRA”) developed by or for MIPS or its predecessor entities.

(c)“MIPS Open Architecture” means Release 6 of the 32 bit and 64 bit MIPS Architecture developed by or for MIPS or its predecessors and licensed under this Agreement (which includes the first version of the MIPS SIMD instruction set architecture, but excludes subsequent MIPS SIMD instruction set architectures and the nanoMIPS instruction set architecture).  The licenses under this Agreement do not cover or include any earlier or subsequent version of the MIPS Open Architecture, or any other version of a MIPS Architecture.

(d)“MIPS Open Architecture IP Rights” means MIPS’ copyrights, patents, patent applications, and other intellectual property rights in the MIPS Open Deliverables delivered to You by MIPS (or a MIPS Open Architecture licensee of this Agreement in compliance with its license under this Agreement). “MIPS Open Architecture IP Rights” do not include copyrights, patents, patent applications or other intellectual property rights (i) that cover implementations of any MIPS Architecture or microprocessor core (including Direct-Licensed Cores and MIPS Open CERTIFIED Independent Cores) except to the extent that such rights are necessary to implement the MIPS Open Architecture in accordance with this Agreement or (ii) that are owned or held by any affiliate or parent company of MIPS or any entity other than MIPS.

(e)“MIPS Open Deliverables” means deliverables for the MIPS Open Architecture or MIPS Open Tools made available by MIPS under this Agreement for You to download from the MIPS Open website upon Your acceptance of this Agreement, as updated from time to time, and includes without limitation MIPS Open Documentation.

(f)“MIPS Open Documentation” means the technical reference manuals for the MIPS Open Architecture.

(g)“MIPS Open Mark(s)” means the MIPS Open CERTIFIED™ mark and logo, and other marks and logos if designated by MIPS as applicable to a MIPS Open license.

(h)“MIPS Open CERTIFIED Independent Core” means a microprocessor core that is an implementation of the MIPS Open Architecture and that (1) You developed independently and internally in compliance with this Agreement  (a “MIPS Open Independent Core”), and (2) has been certified in writing as passing the compatibility verification process under the MIPS Open Architecture (“MIPS Open CERTIFIED”) by MIPS or a MIPS-designated third-party verification provider (each, a “MIPS Open Verification Partner”).   A MIPS Open CERTIFIED Independent Core does not include any: (i) MIPS Open Independent Core that is not MIPS Open CERTIFIED, (ii) core developed in whole or in part from a MIPS Direct-Licensed Core, or (iii) core licensed or provided to You by a third party (unless such core is a MIPS Open CERTIFIED Independent Core that You licensed from a MIPS Open licensee in accordance with this Agreement).

(i)“MIPS Open Tools” under this Agreement means the software, firmware, tools and documentation identified by MIPS as “MIPS Open” under the MIPS Open Architecture, which are posted and accessible in digital form for authorized licensees which are made available by MIPS on MIPS’ designated website(s).

    Verification:

Before manufacturing or commercializing any core implementation of the MIPS Open Architecture licensed under this Agreement, You must ensure that any such core implementation is a MIPS Open CERTIFIED Independent Core (including if you have licensed such MIPS Open CERTIFIED Independent Core from another licensee of the MIPS Open Architecture).  You must notify MIPS in writing of each MIPS Open CERTIFIED Independent Core within thirty (30) days of such verification by a MIPS Open Verification Partner.  You agree to provide upon request by MIPS or its authorized MIPS Open Verification Partner, information demonstrating that such implementation in its current format is a MIPS Open CERTIFIED Independent Core.

And then, once you're done agreeing, you must enter a description of your intended use of the ISA documentation, in english please, to be reviewed within 3 business days and MAYBE they will let you download.

 :wtf:

WTF was all that buzz about "Open source" in the tech press?

This is a completely traditional commercial licensing agreement.

Tech press is clueless. It is pretty clear that MIPS is going down the drain and they are grasping for straws.

It was open the same exact way for years for the university program. And it was just as impossible to actually get your hands on.

And interestingly, the code has not leaked. While ARM's DesignStart leaked many times over before it was officially available to everyone. It is probably because nobody really cares to see MIPS code. Or it was really tough to get it.

Interesting.

A summary of what I got from that (my personal reading only, unrelated to my current employer, and I am not a lawyer):

- the only purpose for which you may use the MIPS ISA specification in the MIPS Open Deliverables is to develop a compatible processor which you will have certified by MIPS

- it appears that you may NOT develop your own core, use it yourself at home or in a private project or embedded in some product and it happens to run MIPS code (e.g. OSes and applications) but you don't tell anyone about it and don't get it certified.

- not only must you get any core you develop certified (is there a cost to this?) but you can't put it on github, because that would allow people who haven't agreed to MIPS' license to access it.

- you can't subset or superset the ISA. 100% compatible only. No extensions. No leaving out the unaligned loads/stores :-)

- the actually interesting modern MIPS ISA -- nanoMIPS -- is not included.

I was actually getting pretty interested in MIPS Open before it actually launched. But the license agreement they came out with clearly sucks.

Not sure what additional benefit there is compared to before MIPS Open, if we still need to get the cores certified by MIPS, something we don't even know whether it's free or not. May cost an arm and a leg. So what's the benefit and how open is that? The "no extension" policy is also terrible.

Now I can understand that going fully open would have been a pretty bold move. I understand allowing anyone to design a MIPS core, call it that and sell it, could harm MIPS' reputation, as they are still a for-profit business. Imagine some "MIPS"-tagged processors get on the market and they are utter crap. Not good for MIPS I suppose, so I can understand the "getting certified" part, if that is the real reason of course... which I don't know.

The sad part would be for MIPS to go down that path and die. Maybe they'll go fully open-source at this point. Or maybe they'll just die with their specs and licensing schemes.

MIPS, aka, Synopsys, aka, same shit on a different package. I expect such software to be as open as a watertight submarine abandoned in the very bottom of the Mariana trench with its hull intact (it is watertight, isn't it?).

Anyway, I avoid MIPS/Synopsys technology as far as I can. It is basically crap. They don't learn with their mistakes, and they seldom release failed designs and pass them off as being great and innovative. Anyway, what would you expect of a company ran by psychopathic managers?

By the way, I'm very "fond" (sarcasm) of the following:

"You will defend, indemnify and hold harmless MIPS and its affiliates and their respective representatives, officers, directors, employees and agents (collectively, “Covered Entities”), from and against any demand, suit, action, liability, damages, cost and expense including reasonable attorney’s fees (“Indemnified Claim”) arising out of or in connection with: (a) Your breach of this Agreement, or (b) the design, manufacture, sale or distribution of Your products incorporating MIPS Open Deliverables. MIPS may elect to defend or settle any part of such Indemnified Claim in its sole discretion, retaining its own counsel at MIPS’ own expense. You may not enter into any license or settlement agreement regarding any Indemnified Claim that might adversely affect any Covered Entities or require any Covered Entities to take any action, forebear from taking any action, or waive any rights, without MIPS’ prior written consent."

I will defend? LOL. Are these guys entitled millennials? This is very laughable.  :-DD

Kind regards, Samuel Lourenço
