Hopefully Qualcomm takes the hint and takes this opportunity to develop a high performance RISC V core. Don’t just give the extortionists more money, break free and use an open standard. Instruction sets shouldn’t even require licensing to begin with if APIs aren’t copyrightable. Why is it OK to make your own implentation of any software API (see Oracle vs. Google on the Java API, Wine implementing the Windows API, etc) but not OK to do the same thing with an instruction set (which is just a hardware API). Why is writing an ARM or x86 emulator fine but not making your own chip? Why are FPGA emulator systems legal if instruction sets are protected? It makes no sense.

The other acceptable outcome here is a Qualcomm vs. ARM lawsuit that sets a precedence that instruction sets are not protected. If they want to copyright their own cores and sell the core design fine, but Qualcomm is making their own in house designs here.

They might. This would never be open sourced though. Best case scenario is the boost they would provide to the ISA as a whole by having a company as big as Qualcomm backing it.

RISC V is just an open standard set of instructions and their encodings. It is not expected nor required for implementations of RISC V to be open sourced, but if they do make a RISC V chip they don’t have to pay anyone to have that privilege and the chip will be compatible with other RISC V chips because it is an open and standardized instruction set. That’s the point. Qualcomm pays ARM to make their own chip designs that implement the ARM instruction set, they aren’t paying for off the shelf ARM designs like most ARM chip companies do.

The RISCV instruction set IS open source. What they’d do to ratfuck it is lock the bootloader or something.

If Qualcomm released a FOSS RISC-V IP core that would’ve required spending multiple millions on hardware engineer salaries (no chance in hell), I would:

  1. Spontaneously ejaculate
  2. Pull out my FPGA

In the mobile Linux scene, Qualcomm chips are some of the best supported ones. I don’t love everything Qualcomm does, but the Snapdragon 845 makes for a great Linux phone and has open source drivers for most of the stack (little thanks to Qualcomm themselves).

Development is never free, especially, if you have to build new knowhow and can not build upon the one they have built at development of ARM chips.

This is a big ol’ game of bluff from both sides. So, according to you, Qualcomm should call their bluff?

Saying an ISA is just a hardware API vastly oversimplifies what an architecture is. There is way more to it than just the instruction set, because you can’t have an instruction set without also defining the numbers and types of registers, the mapping of memory and how the CPU interacts with it, the input/output model for the system, and a bunch of other features like virtual memory, addressing modes etc. Just to give an idea, the ARM reference is 850 pages long.

APIs can be complex too. Look at how much stuff the Win32 API provides from all the kernel calls, defined data structures/types, libraries, etc. I would venture a guess that if you documented the Win32 API including all the needed system libraries to make something like Wine, it would also be 850 pages long. The fact remains that a documented prototype for a software implementation is free to reimplement but a documented prototype for a hardware implementation requires a license. This makes no sense from a fairness perspective. I’m fine with ARM not giving away their fully developed IP cores which are actual implementations of the ARM instruction set, but locking third parties from making their own compatible designs without a license is horribly anticompetitive. I wish standards organizations still had power. Letting corporations own de-facto “standards” is awful for everyone.

This will get RISC-V probably a big boost. Maybe this was not the smartest move for ARMs long term future. But slapping Qualcomm is always a good idea, its just such a shitty company.

True, I just wished RISCV laptops were slightly more developed and available. As of now, the specs aren’t there yet in those devices that are available. (8core@2Ghz, but only 16GB Ram, too little for me)

Kind of a bummer, was coming up to a work laptop upgrade soon and was carefully watching the Linux support for Snapdragon X because I can’t bring myself to deal with Apple shenanigans, but like the idea of performance and efficiency. The caution with which I approached it stems from my “I don’t really believe a fucking thing Qualcomm Marketing says” mentality, and it seems holding off and watching was the right call. Oh well, x86 for another cycle, I guess.

I think, I would go for a ARM Tuxedo PC in your position.

Oh, still some time needed for that as well, but you can see the progress (a lot is working now at kernel 6.11)

ARM CPU prob means that at some point you’ll get stuck with a kernel limit.

But did you imply you would buy (now) a RISC-V laptop if it had more RAM & cores?

You are overestimating RISC-V. It cannot save the planet alone.

ARM provides complete chip designs.

RISC-V is more like an API, and then you still need to design your chips behind it.

I could be wrong, but I think Qualcomm designs its own chips and only licenses the “API”, so it would be no difference for them.

If they use Cortex cores, they are ARM designs. Oryon cores are in house based on Nuvia designs, and I assume it would still require a complete chip redesign if they decide to switch to RISC-V.

From my understanding, most companies take the reference design from Arm and then alter it to fit their needs.

Of course i will still take RISC-V a long time to be even relevant. But in the future there could be multiple Companies that offer finished chip designs to use. As you said not every company wants and can create a design themself.

Several differing extensions of the RISC-V core machine instructions, for example. A pain in the rear for any compiler builder.

Yeah, in the current macro environment Qualcomm isn’t that tied down & can afford some changes (basically with a few of their biggest partners that can keep their profits up even in a few transitioning years). Not sure what prompted ARM to force such a deal instead of getting like a good compromise.

But also fuck Qualcomm & their closed-softwareness.

Im still hoping I can buy a RISC-V laptop (from Framework?) in 2 or 3 years & just run Linux normally.
And if that can happen & RISC-V still doesn’t overall prosper it’s bcs of some shitty greedy deals between megacorps.

For a firm that already have their own core designs that simply use the ARM instruction set, it might be easier to adapt to RISC-V. For a firm that licenses ARM cores on the other hand…
