[r0tten-ruzt]

I'm thinking about making a rust!sbi x dsmp crossover au. I wanna change the names of them to just for fun or have them as like code/nick names?? They're still the characters and called by that but I also wanna give em other names. I already have "Anu soot" (might change the soot but i dont have any ideas i want it to kinda be simular to soot) for c!wilbur and I'm thinking about tommy rn. Give me yalls opinions on it^^

Rust Compiler Performance Triage

A fairly quiet week with regressions unfortunately slightly outweighing improvements. There was not any particular change of much note. Many of the regressions were justifiable since they were for critical bug fixes.

Triage done by @rylev. Revision range: 96ddd32c..a78c9bee

Summary:

(instructions:u) mean range count Regressions ❌ (primary) 0.7% [0.2%, 3.0%] 76 Regressions ❌ (secondary) 1.5% [0.3%, 8.4%] 69 Improvements ✅ (primary) -0.7% [-1.8%, -0.2%] 18 Improvements ✅ (secondary) -1.4% [-3.2%, -0.2%] 35 All ❌✅ (primary) 0.4% [-1.8%, 3.0%] 94

7 Regressions, 4 Improvements, 6 Mixed; 5 of them in rollups 47 artifact comparisons made in total

Call for Testing

An important step for RFC implementation is for people to experiment with the implementation and give feedback, especially before stabilization. The following RFCs would benefit from user testing before moving forward:

No RFCs issued a call for testing this week.

If you are a feature implementer and would like your RFC to appear on the above list, add the new call-for-testing label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature need testing.

Approved RFCs

Changes to Rust follow the Rust RFC (request for comments) process. These are the RFCs that were approved for implementation this week:

No RFCs were approved this week.

Quote of the Week

While working on these userspace Mesa changes today, I did not hit a single GPU kernel driver bug. Not. A. Single. Bug.

This is thanks to Lina's phenomenal efforts. She took a gamble writing the kernel driver in Rust, knowing it would take longer to get to the first triangle but believing it would make for a more robust driver in the end. She was right.

A few months of Lina's Rust development has produced a more stable driver than years of development in C on certain mainline Linux GPU kernel drivers.

I think... I think I have Rust envy 🦀

....Or maybe just Lina envy 😊

– Alyssa Rosenzweig tooting on Mastodon

Thanks to Brian Kung for the suggestion!
