What would you look forward to being on the Raspberry Pi 5 ?

I remember people were really keen for more USB ports, for a standardised board layout, for more GPIO, for customisable GPIO, for Wireless LAN / WiFi, Bluetooth, faster ethernet, faster USB, and being a 64bit, quad core, faster processor.

And, we have all of that. We even have the compute module with pcie broken out.

What would you want on the Raspberry Pi 5?

Subsystem that supports deterministic timing (like RP2040 Pio or BB Pru)

Less power, less heat

Support for external antennas for the wireless functions

TPM 2 hardware module and drivers for it in the software releases

You just beat me to it, a PRU !!

(and decent high speed drivers to support it !).

The RP2040 state machine GPIO is a possibility but a PRU would be better.

Not what I would really like, the RP2040 will become a restirction.

The 2040 GPIO system tightly coupled to the Pi5 cores would be much better.

A clone of the TI PRU would be much better still, but the RPi people are much more likely to be able to do the 2040 IO system.

Another reasonable thing would be any kind of really fast bi-directional pipe that could link to an FPGA.

My problem with the Pi, and pretty much every single board Linux or Windows capable computer is that while you have a really fast processor (or 4 of them) there is no way simple to get data in and out at high speed.

So while the Pi could easily crunch the data from a 100MHz ADC there isn't a simple way to get it into the processor.
