Not quite. From Marcan on Mastodon:

> Good for me, means I can re-send our patch that rips out the (now confirmed useless and non-functional) Cypress WPA3 support and replaces it with the Broadcom WPA3 support that does actually work on Broadcom chips in Apple machines.
> We've had WPA3 in Asahi Linux since forever, the only reason it's not upstream yet is because the Broadcom maintainer guy was worried that ripping out the Cypress thing (that nobody knows about, and Cypress guys gave us the silent treatment when we sent them emails asking) would break Cypress. Looks like Cypress is already broken, so there.

So my understanding is that Broadcom (on Mac) and Cypress (on Raspberry Pi) are not the same chipset but maybe they previously shared a driver? Or something like that.
Now that they know Cypress is broken anyway, they can go ahead and fix Broadcom.
- mcbridematt 3y agoThe Cypress chipset used to be a Broadcom product. Broadcom decided to sell the 'IoT' side of their WiFi/BT product line.
- mcpherrinm 3y agomy understanding is: Cypress bought the embedded/IoT wifi department from Broadcom, including a bunch of IP, and uses a shared wifi driver with other Broadcom wifi chipsets, with some shared maintainers. The driver in question is brcm80211 https://patchwork.kernel.org/project/linux-wireless/patch/1498125664-25980-5-git-send-email-arend.vanspriel@broadcom.com/ https://patchwork.kernel.org/project/linux-wireless/patch/14... https://investors.broadcom.com/news-releases/news-release-details/cypress-acquire-broadcoms-wireless-internet-things-business https://investors.broadcom.com/news-releases/news-release-de...
- jacquesm 3y agoThe whole WiFi story on Macs is beyond silly. I recently did this on a recent model Macbook Air after installing Linux on it and ended up with a dock and an ethernet cable because I needed the files that were present on the box before installing linux because there are so many variations that this is the only failsafe way to get WiFi that actually works.
