The Hazard 3 is basically a hobby project of Luke Wren, a Raspberry Pi Employee. He's contiuing to evolve it further, but I don't think it's ready for a full replacement of the Cortex-M yet, especially in regards to the Security Features.

The source code is all from Luke Wren and I don't think other cores use the source code directly, but improvements to test harnesses or general implementation patterns as well as better software support help other cores: https://github.com/Wren6991/Hazard3

For the SoCs I would expect to see an off-the-shelf Risc-V core (certainly no Hazard3 as the main CPU), but we'll see.

The Hazard3 in the Pico 2 are bigger, more capable cores than the Cortex-M0 in the first Pico, and therefore in general faster at the same clock for compiled code.

You're supposed to be able to just recompile most Pico projects to use them as long as there is no ARM assembly in it.

They are only inferior to the ARM Cortex-M33 cores in the Pico 2.

So they come inferior in the only place it matters, gotcha

I know the "basically" is probably doing a bunch of heavy lifting, but dang, that's still awesome to think about. I didn't know hardware development was at the point where a hobby project CPU, apparently mostly developed by one guy, can realistically end up in a mass produced product like that.

Quick edit: sounds like "basically" wasn't doing that much heavy lifting after all, wow https://www.raspberrypi.com/news/risc-v-on-raspberry-pi-pico...

linux started as a hobby project...

I am curious to know which RISC-V design they'll go for in this SOC.

M. Wren getting real hard experience on RISC-V is going only to help RP to select and audit more seriously any RISC-V design which would make its way in their SOCs.

I just don't want to contribute to arm IP racketering (and we have mpeg and hdmi to take into account too with avX and eDP/DP).
