Makes sense as looking like she started after the first basic submissions where made for the rk3588 by
Sebastian Reichel
https://lore.kernel.org/lkml/20220422170920.401914-1-sebastian.reichel@collabora.com/
Which suddenly has got up to speed https://lore.kernel.org/lkml/?q=rk3588
So based on https://lore.kernel.org/lkml/20220426132139.26761-5-linux@fw-web.de/
PCI IP in SOC use Synopsys IP
I think Rockchip are employing collabora specifically but a lot of big names in the Arm world in that list. Far beyond my pay grade 
Great to see things get such traction irrespective really of not knowing that much to what they entail.
Whoever though its got a lot of action by some very technical people.
They just “sign” the patch so don’t expect any big work. This is mainline linux kernel development. Everything is in heavy development and untested
Yeah seems Peter Geis who has been doing a lot with the rk356x, Sebastian Reichel with Alyssa on Panfrost (collabora) but does seem to be moving at a pace finally after nothing rk3588 really apart from the early rockchip submissions.
I guess they are trying to get as much of a base into 5.18 before its release and then we have the ongoing release schedule of approx 3 month steps that will be a long wait for each incremental addition.
I think the Android implementation is quite a bit ahead though which is also interesting with android 12.
I doubt we will get it but the ASR currently on the Pixels is amazing stuff, likely it will be retained as part of the Pixels crown jewels.
I am going to spend my time with the highly likely earlier release of the RadxaZero2 and the RockPiS just perked my interest once more as maybe the ADC is less noisy now?
I agree. The form factor of the Rk3588 sbc looks amazing! I’ve owned a khadas vim 3 for about three years now and I like it’s form factor except the nvme slot is backwards so it isn’t ideal if a case is desired. I like the slightly bigger board because it fits everything I want on it.
I didn’t realise that with the Vim3 but yeah now I look there is no mounting pillar which is a crazy idea to me on a picoITX format board which with the Rock5 I think is a great format and hopefully it will be the end of Pi clones as actually think that format is not good as opposed to a more mobo format of 1 plane or vertical.
Raspberry have been very successful but for me SBC have outgrown that format.
This one has 2-pin socket, GND+5V only and rock3 has 3 pins (+PWM) and much smaller connector. This won’t fit including screw mount holes designed to other board than rock3A
edit: on first photos it seems that fan header is same as on rock3a (3pin) so I assumed that there should be something similar to rock3a. Of course if its that white header near emmc. If this is changed to 2pin then any 5v fan could be used if You can attach it there. This one won’t fit - it has different screws location.
On the other end they have super fitted nvme extension board to mount it. It’s super slim and much better than something like on rock pis. Of course it won’t fit factory case anymore but it’s not problem for everybody. For me nvme slot speed is disappointing - it’s only 1x lane 
and according to specs for vim4 it will still have 1x lane
Upgrade RADXA boards 3B and 5B with active heat management.
Works as well with e.g. Starfive VisionFive SBC
Doesn’t say its for the Rock3A but that is what is in the shop and what Radxa are providing not sure if the pre-release images are exact to what we might get as a production release.
@jack
True, I just assumed that there have to be something like for Rock3A because from release photos it’s probably the same 3P connector. That may be changed on final product as @jack said 
For starfive fan also mounting holes are specific, so I don’t think this would be good choice.
There are some fans for RBpi with 5V + PWM pins, they can be controlled from GPIO: https://wiki.52pi.com/index.php?title=F-0012
To be honest I don’t see the point in PWM but guess for us in different climes or load it give ability to set different speeds.
You can just stick a 12v on 5v or a 5v on 3.3 and both silent and loads of air flow.
Yeah I agree. I also purchased a Rpi4 back in 2019 and I have been extremely impressed with the amount of support it gets, I mean my vim3 can’t do stuff(run 64 bit android apps) that the Rpi4 can do with much less cpu/gpu juice! This is why I’m so excited about what Rockchip is doing with the rk3588 soc!
Yeah Raspberry make 100% profit on all there boards and think it was £10M last year and there is no comparison really to a relatively small outfit like Khadas.
The Radxa Zero2 is out soon which also is an Amlogic A311D which also complements the previous Zero Amlogic chip so you can counter revenue if you get a big enough herd so maybe Khadas will also benefit.
Rockchip is throwing some weight behind Android also Linux but like all many of these boards are fresh and part of a development and support cycle based on number of users and funds.
If you don’t get the herd (numbers) or enough funds without a lot of manufacturer SoC support things can be very slow or even freeze.
The Radxa Fan 4012 is 2P and currently work with pico-itx boards only(3B/5B/VisionFive), not the pi form factor because of the size limitation.
Is there any ETA on the board? Even a rough estimate?
I’m wondering the same thing. A popular youtuber made two videos featuring the rk3588 soc and oh my! I can’t wait the the single board computer powered by this amazing soc
@radxa, I haven’t found the answer in the thread. Do you know if the penta hat available for the rock 4 will be compatible with the rock 5?
If i may ask. Is that 100% profit a typo or it was meant as a sarcasm? Can’t figure that out definitively as english is not my mother tongue. Thank you in advance.
