@jmorris off-topic but i have this sound card called "RME BabyFace Pro FS". it has pretty cool idea for FPGA's: the mixer is an FPGA. With this topology it can reach 1 ms latency for audio. And i.e. a firmware update contains also potentially update for the FPGA. Pretty clever hybrid approach IMHO.

Before I got this sound card I was not really sure where application wise it would make sense to have e.g. a SoC combined with FPGA but this product made me understand it a bit better.

I also own one small lattice FPGA. As soon as I get an idea how to use it e.g. with RPi for similar hybrid thing I'll definitely will PoC something. Lattice's have the benefit of having open source FPGA stack and since I also have a SoC FPGA does not have to have too many logic ports.

probably will get some feedback from linus but i'm in middle of changing my process (by request), so i'll just then apply learnings to 6.11 🤷

Splitting my pull request. For v6.10 not yet fully finished/polished but the idea is to have simple script to create the PR from signed git tag and then have a few #aerc templates for each subsystem:

https://lore.kernel.org/linux-integrity/D15DSV117DQZ.3GJOTXCTGZHE9@kernel.org/T/#u

Two first I did for keyring and trusted key did not yet use this scheme but learned along the way that I need to scale a bit. Slowly figuring out how to do this properly.

@jstultz I'll check all tracing tools and debuggers as they come by :-) QA is fun!

(speaking for myself here) One of the cooler things about Google is getting just the slightest glimpse of the power of some of the tooling your wizard coworkers use.

https://perfetto.dev/ is one of those very cool tools. It's like kernel shark, but has really powerful SQL capabilities. It's well configured for use with Android and CrOS, but with classic Linux environments it can be a little daunting. So here are my notes on using it for upstream kernel development: https://gist.github.com/johnstultz-work/0ec4974e0929c4707bfd89c876ae4735

@yassie_j Have to say tho that I've only worked with super smart people from India so AGI ("A Guy from India") must/will be great :-)

@liw in computing i tend to prefer cache hits, in real life cache misses

In colloquial computing Finnish the work for a cache is "kakku", because it's similar in pronunciation. Kakku means "cake". Thus, in Finnish people ask each other how much cake their CPU has.

Language is funny.

Co-authored an update from the @MastodonEngineering team with my friend @renchap - a sneak peek at what is coming in 4.3 (and looking ahead from there). We'll aim to make these updates a regular feature for the blog. Let us know what you think! https://blog.joinmastodon.org/2024/05/trunk-tidbits-april-2024/
