Karl, if you can substantiate that Chrome is already pushing wasm SIMD content to consumers I really would like details. The referenced bug seems to be ambiguous on this point.

Flags: needinfo?(kdubost)

Lars, that's a good question,

They send this file when using meet.google.com with Chrome Canary (I haven't tested on Chrome release)
https://meet.google.com/_/rtcvidproc/release_1dttl/343495590/mediapipe_wasm_simd.wasm

But I do not know wasm :)

The source is loaded through a blob blob:https://meet.google.com/47e842ef-319d-4c7e-ab17-5161db67cdc4
when interacting with Google Meet. So I don't know if it's the case, but you might understand better.

  1. with chrome canary
  2. Go to https://meet.google.com/
  3. authorize camera and audio
  4. Tap on the background icon at the bottom right of the video insert
  5. A panel opens
  6. Change to background blur

You should see in the network panel of the devtools a request to mediapipe_wasm_simd.wasm
in the search tab you can search for simd.

Flags: needinfo?(kdubost) → needinfo?(lhansen)

I may be wrong, but I believe that is in the current origin trial for wasm SIMD in Chrome,

https://v8.dev/features/simd#simd-origin-trial

Alon, thank you - excellent point!

Karl, it also would make sense for this content to be served to Canary.

I think I'm going to stop worrying about this :-)

Just an update, Chrome 91 (stable by May 25) will enable WASM SIMD for SSE/AVX/NEON by default.

Yeah, tracking this. Thanks.

I should mention, we're shipping x86/x64 (SSE) in FF89 (release date June 1) and arm64 in FF90 (release date June 29).

We're done, and shipping is controlled by other bugs, lowering to P3.

Sorry. I don't precisely understand how this works. Does this mean SIMD has been implemented in FireFox, and will ship fairly soon?

Depends on: 1709877

Thank you, Yury.

SIMD has landed in Firefox and is riding the trains to release: Firefox 89 for x64, x86, Firefox 90 for arm64.

No support is planned for arm32 or mips64.

Remaining bugs linked from this one are currently for cleanup and improved code generation; reported defects should be linked to this bug too until this bug is closed.

Nice! Thank you for explaining things clearly, Lars. Much appreciated.

Webcompat Priority: --- → ?

Karl, FWIW, SIMD has shipped on x86, x64, and arm64 (and that's where we intend to stop). The remaining dependencies are all optimization items + relaxed simd, which is an emerging bolt-on.

Thanks Lars!
