Running The Open-Source Upstream V3D Driver On The Raspberry Pi 4 & Newer

[slalomsk8er]

Don't they use the same SoC? It only counts as "newer" if it's not the same as in the original Pi 4.

From what I can see, they all use the BCM2711, though the 400 uses a C0 stepping. It seems extremely unlikely that any significant design changes would be introduced in a stepping, rather than a new model number.

Product wise they are newer but you are right SoC is the same but the article mentioned Pi 4 and not BCM2711

So what drivers are still missing out of a stable-line stock Linux kernel then? When are you going to be able to just load up a stock version of Fedora and have every piece of hardware in an RPi4 supported?

And when can we expect to see decent support for ARM GPU-accelerated greaphics and video in a web browser (ANY web browser!) without a massive hit to CPU or janky YouTube H.264 hack plugins?

And when are we going to see the mass adoption of a standard firmware interface for ARM, like System Ready??? Cuz until then, ARM ain't ready...

Any benchmarks planned to compare the different Pis? The new Orange Pi 5 seems to be interesting price wise, f. e.

It's a RK3588 board! That means 4x A76 + 4x A55, and a better Mali GPU.

It also has a NPU, but I have no idea what state the software support is in, nor is it a priority for me to find out.

I think the standard Pi 64-bit install now gets most of its packages directly from Debian repos, though there still is one Pi-specific repo.

No, I don't have any of the other non-RPi ones.

Here's the Ali Express link for Orange Pi 5. If you're interested, PM me the total price (shipped) and I'll reimburse you via paypal:

Looks like it should end up somewhere in the ballpark of $95.10, which is by far the best price I've seen on a RK3588 board!

Make sure to get the 8 GB kit with the US power adapter.

Feel free to add their crappy little heatsink:

I expect it will need something better, to avoid throttling. Perhaps we'll see. I never use the adhesive on those things. I clean it with isoproply alcohol and then use a PC-grade heatsink compound. As I discovered on the Pi 3, it still doesn't make up for using a crappy little aluminum heatsink, when what you really need is a big copper one.

Or this one, which is the biggest copper heatsink I can find that will fit:

It's 20 mm x 20 mm x 7 mm high. The white outline on the PCB is about 19 mm x 19 mm, but I figure there's no harm in putting it a little off-center or even crowding the RAM.

Not the kernel. It's still a mess.
