MediaTek is still available.

Without (complete) kernel sources, they're already e-waste.

No problem, as they are used in chromebooks:

Your view even of human languages is simplistic. Forgive me, I don't mean to be rude, I'm just trying to explain. You might think that languages are just have different words for the same things. In reality the problems are where the same things don't exist. People don't view the world the same way and don't have an equivalent word. In Turkish it's very important whether your aunt is on your mother's side or your fat…

It's interesting that many with CS/CE background believes in irreversible death of Sapir-Whorf hypothesis and victory of the Universal Grammar Theory, while many from the exact same cohort are able to trivially explain how tightly coupled ISA and CPU implementation are and how mutually incompatible different ISAs can be. I mean, it's most likely overlaps and not actually the same set of people, but I find it ironic a…

I suspect that it's an argument about nothing. e.g. I can think about my "mother's sister" but I don't care about it enough to invent a shortcut word for it like "teyze". To Turks I think it means something because in some families there's great emphasis on the connections with one or other side of the family. It's rather a brutal and dismissive attitude sometimes.

So I personally think that groups of people have a common understanding and some commonly accepted attitude that make up their culture. The purpose of words is to reference those feelings. An outsider can understand to a degree because we are all human but they usually get the emphasis wrong and also tend to miss lots of implications.

Of course you as an entrant to a culture (e.g. a kid) are going to get educated over time about what it all means and you're going to be discouraged from expressing alternate cultural values because overall not enough people feel like that to have invented convenient ways of expressing it.

So language is going to affect you but as some idea becomes popular and needs expression people do invent new words. So you can affect it - if you can get enough people to pick up on your invention by adding a new idea to their mental model of life.

There's a missing word here (which otherwise makes the sentence nonsensical): "He’s also expanding into new areas, most notably computing, where Arm is making its own push." I'm guessing cloud computing, but guess you could add any buzzword in...

Another odd word choice early in the piece:

> their so-called architectural license agreement

Definition 2 is when this tends to be used: https://www.merriam-webster.com/dictionary/so-called

Qualcomm is slightly bigger than ARM so it seems like a fair fight to me. Does Qualcomm police it's IP at all?

> Qualcomm is slightly bigger than ARM so it seems like a fair fight to me. I'm not really sure what you're responding to. It's got nothing to do with size whether or not something is fair, it's what is in the contract. None of us know exactly what's there so if it becomes disputed then a court is going to have to decide what is fair. But that was entirely not the point of my comment though. I'm talking about how cor…

You might be right, but they do perhaps also have to establish that their contracts are going to be defended/enforced. Otherwise they have nothing.

People also seem to forget that everything needs to be ported. If you're an Android manufacturer, you're not going to stop shipping phones, waiting for the Android RISC-V to catch-up to ARM, or for RISC-V to get the speed and features of current ARM CPUs. You're going to buy ARM processors from another vendor. The Windows ARM port is going to take even longer, I doubt that Microsoft has that working at anything beyon…

In theory, the Raspberry Pi foundation could easily move 3 million 1.8GHz RVA23 in 1 quarter... with 64 cores + DSP ops it wouldn't necessarily need a GPU initially. =3

The Raspberry Pi community would probably jump on a RISC-V board, but that doesn't help Qualcomm or it's customers.

Last time I checked, Qualcomm did not introduce any custom instructions into the ISA. What damage are you speaking of?

The merge of the Qualcomm architecture with the Nuvia IP they acquired, which was created under a far-reaching license ARM granted to Nuvia. Combining both creates a custom architecture different from ARMs consolidated and harmonized designs offered to licensees (i.e. Blackhawk or Cortex-X). The IP of Nuvia was not supposed to be used in all the use-cases that Qualcomm intends to deploy it in (and moreover there is s…

Ah? ARM doesn't build chips but provides the architecture and license it to other companies. There are plenty of ARM chips designed by multiple companies and built by multiple foundries

ARM licenses cores for both CPU and GPU, not just the architecture. There are not “plenty of ARM chips designed by multiple companies”, almost all of them except for Apple (and now Qualcomm) use ARMs off the shelf design.

Qualcomm have a Plan B. This time last year they were all over the RISC-V mailing lists, trying to convince everyone to drop the "C" extension from RVA23 because (basically confirmed by their employees) it was not easy to retrofit mildly variable length RISC-V instructions (2 bytes and 4 bytes) to the Aarch64 core they acquired from Nuvia. At the same time, Qualcomm proposed a new RISC-V extension that was pretty muc…

Dropping "C" overnight and thus making all existing Linux software incompatible is completely out of the question. Android was never really Linux though.

Dropping the compressed instructions is also a performance / power issue. That matters to mobile.
