What's the advantage of standardizing through ISO/IEC? Better adoption in industry?
Seems like this would take away a lot of power from RISC-V International. But I don't know much about this process.

Random example I found at a glance: NIST recommending use of a specific ISO standard in domains not formally covered by a regulatory body: https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.S...
Is ISO as an organisation imperfect sometimes (as in the docs case) sure?, it’s composed of humans who are generally flawed creatures, is it generally a good solution despite that?, also sure.
They’ve published tens of thousands off standards over 70 plus years that are deeply important to multiple industries so disregarding them because Microsoft co-opted them once 20 odd years ago seems unreasonable to me.
Of course this is a lie. But yes, governments like to claim that.
> “International standards have a special status,” says Phil Wennblom, Chair of ISO/IEC JTC 1. “Even though RISC-V is already globally recognized, once something becomes an ISO/IEC standard, it’s even more widely accepted. Countries around the world place strong emphasis on international standards as the basis for their national standards. It’s a significant tailwind when it comes to market access.”
I guess you just never had to fill in a grant application where you have to justify that you are using official standards so that you can get money
Without these profiles, we are stuck with memorizing a word soup of RV64GCBV_Zicntr_Zihpm_etc all means
You will find fossilized languages all over the place.
However even with profiles there are optional extensions and a lot of undefined behaviour (sometimes deliberately, sometimes because the spec is just not especially well written).
It started with G, later retroactively named RVA20 (with a minor extra extension that nobody ever skipped implementing), then RVA22 and now RVA23. All application processor implementations out there conform to a profile, and so do the relevant Linux distributions.
Of course, in embedded systems where the vendor controls the full stack, the freedom of micromanaging which extensions to implement as well as the freedom to add custom extensions is actual value.
The original architects of the ISA knew what they were doing.
“We’re standards compliant”
Other times, like with the "ISO power plug", the result was ISO/IEC 60906-1 which nobody uses. Swiss plugs (IEC Type J), which this plug is based on, use a slightly different distance for the ground pin, so it is incompatible. Brazil adopted it (IEC Type N) but made changes to pin diameter and current rating.
If the choice is between an architecture owned, patented and managed by a single company domiciled in a foreign country, versus one which is an international standard and has multiple competing vendors, the latter suddenly seems a lot more attractive.
Price and performance don't matter that much. Governments are a lot less price-sensitive than consumers (and even businesses), they're willing to spend money to achieve their goals.
(It's still a trade-off, because standards also cost community time and effort.)

It didn't become one, but it did become standardised as ECMA-234:
https://ecma-international.org/publications-and-standards/st...
>In February 1994, the PWI Specification Committee sent a draft specification to X/Open—who rejected it in March, after being threatened by Microsoft's assertion of intellectual property rights (IPR) over the Windows APIs
Looks like that's what it was.
I just hope it's going to be a "throw it over the fence and standardize" type of a deal, where the actual standardization process will still be outside of ISO (the ISO process is not very good - not my words, just ask the members of the C++ committee) and the text of the standard will be freely licensed and available to everyone (ISO paywalls its standards).
Casual reminder that they ousted one of the founders of MPEG for daring to question the patent mess around H.265 (paraphrasing, a lot, of course)
