Use GPUBuffer in GPUBindingResource

[beaufortfrancois]

Spec PR: gpuweb/gpuweb#5193

[beaufortfrancois]

FYI It requires gpuweb/types#182

LGTM but marking draft as we need to wait until all browsers support this.

[greggman]

Thanks for this PR. I like this new style!

Agree with @kainino0x, we shouldn't merge this until all browsers support it and it's shipped in Chrome stable, and maybe given it 2+ weeks or after that.

@jimblandy @mwyrzykowski Are there existing browser bugs/tickets I can follow to keep track of those changes?

Yes, WebKit bug is https://bugs.webkit.org/show_bug.cgi?id=294006 @beaufortfrancois

@jimblandy @mwyrzykowski Did Firefox and Safari implement this change? If so, I'l update our WebGPU samples with that PR.

[greggman]

https://webgpureport.org/ shows a warning if it's not implemented. From that

• firefox stable has implemented it
• Safari stable has not
• Safari Technology Preview has

[beaufortfrancois]

Thanks @greggman! Let's wait until it reaches Safari Stable then.

[mwyrzykowski]

WebKit has @beaufortfrancois :)

[mwyrzykowski]

@greggman did you try Safari 26.2?

[greggman]

@mwyrzykowski, my Mac had not told me to upgrade yet 😄 . I updated to MacOS 26.2 and can verify that Safari 26.2 supports this.

tangential question: Safari TP no longer supports WebGPU on MacOS 15 right, or at least it stopped working for me. My work machine is still MacOS 15.7.3, my personal machine is now 26.2. I have not been able to use Safari TP on MacOS 15 to test WebGPU for a month or 2. Is that expected?

As for this PR. We might want to give it a couple of weeks to let more people update to 26.2 before breaking it for people still on < 26.2.

That's correct, it was disabled with https://bugs.webkit.org/show_bug.cgi?id=299237 since we removed some underlying framework workarounds for OS versions < 26.0

Sounds good to me 👍
