riscv-v-spec VS flameshot

Here are some resources I can recommend:

RVV spec (also look at the examples in the repo): https://github.com/riscv/riscv-v-spec/blob/master/v-spec.ado...

RVV intrinsics viewer: https://dzaima.github.io/intrinsics-viewer

Tutorial: RISC-V Vector Extension Demystified (3 hour video going over every instruction): https://youtu.be/oTaOd8qr53U

RISC-V Vector extension in a nutshell: https://fprox.substack.com/p/risc-v-vector-extension-in-a-nu...

If you want to see a more complex example/real world application, then you might also be ibterested ib my article about vectorizing unicode conversions: https://camel-cdr.github.io/rvv-bench-results/articles/vecto...

In terms of development I'd recommend using qemu and a cross compiler, or if you want hardware try to get the kendryte k230 (currently the only sbc with rvv 1.0 support) or wait a bit for better hardware (BPI-F3 and sg2380 should release this year).

And this isn't just some theoretical or something unlikely to happen - the official spec already contains such a bug. If the writers of the spec can't get things right, even with the small amount of code in the spec, I don't have high hopes that less informed programmers will. RVV being absurdly complicated (IMO, compared to SVE2 and AVX10) doesn't help its cause here.

Will the reference one actually be the most optimal one on future hardware?

I'll do a deep dive into the https://gms.tf/riscv-vector.html#getting-started tutorial, and probably pop the proverbial stack and just study RVV 0.7.1 on its own (using https://github.com/riscv/riscv-v-spec/releases/tag/0.7.1).

I see your point. You can file a request for it at https://github.com/riscv/riscv-v-spec/issues if you want to pitch it to the relevant ISA bodies. The bar for implementing it pretty high.

It's not "unusual"; using data registers for mask is a valid tradeoff especially for low-end implementations, whereas higher-end architectures can easily use shadow registers. Discussed in depth at https://github.com/riscv/riscv-v-spec/issues/811

I'm using flameshot ( https://flameshot.org/ ), which sounds pretty similar, but FOSS and cross platform.

For your screenshots simply use Flameshot: https://flameshot.org

First, conceptually this is what I mean: think about when using a good screen-capture/annotation tool like flameshot: you select a region of the screen, and "magic" you can "edit" it, "in situ". No, what I'm talking about wouldn't share any of the same technical underpinnings with the way flameshot works, it would be the live monitor output, not a raster dump of the screen made to look like it's live. And the annotating would be done on a different screen. But as a user, this is pretty similar.

Flameshot is a free and open-source screenshot tool for Linux that allows users to take screenshots of an area, a window or the full screen. It then provides an editor where users can modify the screenshots by drawing on them, adding text, highlighting areas, blurring parts and more. Users can save the screenshots in common image formats like PNG and JPEG, and upload them directly to image hosting sites like Imgur.

I would recommend Flameshot, available on Linux, Windows and Mac.

This https://github.com/flameshot-org/flameshot/issues/1529 mat or may not be an issue for you with Flameshot, but it may be for others. It's solvable if it is an issue by using mandatory access control such as AppArmor or conditional build. Just FYI.

Flameshot viene con todo eso.
