Hello theWhip. Welcome to LQ.

It seems the new firmware fix is certainly "fixing" things good and proper: Raspberry Pi 4 - new VLI firmware issues

It's been reported that the new VLI firmware fix lowers the general operating temperature of the SOC by only a few degrees and that's without any additional cooling. New Raspberry Pi 4 VLI Firmware Lowers Temperature by 3-5°C. If the new firmware only lowers temperatures by 3-5 degrees Celsius, that's not very much and is approx. the same as adding a 28x28x20mm heatsink to the RPi4 SoC - without a fan. I have tested with this heatsink setup and the thermal issue is still very apparent. The only way to cool down the RPi4 SoC effectively is to use a heatsink and fan as an additional cooling solution.

If you would like to install the new VLI firmware "fix" [as recommended by Raspberry Pi Engineers] to solve the thermal issue(s): Following a successful trial with our alpha testers, we are releasing a new firmware build for the USB3 host adapter.... Good luck if you do!

Thx for the Info, i already install the new firmware and use two small heatsink units without any fans, not yet.
Seems i should overthink my solution

A guy I spoke to is running his Raspberry Pi 4 Model B in a GeeekPi Acrylic Case with a Noctua 40mm 5v fan fitted and he reports the operating temperature to be ~35'C when idling at the command prompt. That's without any heatsinks fitted at all.

Apparently, so I'm told, the Noctua 40mm fan is very efficient and quiet. I'm looking to get one.

I like that GeeekPi Acrylic Case, yes Noctua 40mm fans are really cool!

This seems like the best thread to make acknowledgements, so:

I installed slackwarearm -current on an RPi 4 today - successfully! I've already learned a wrong way and the right way to update the kernel.

A big thank you to all of you who made that possible: Pat, of course; MoZes for Slackware ARM; and exaga for SARPi.

Also to anyone I've missed - others who contribute directly to Slackware and to Slackware ARM, are named on arm.slackware.com and sarpi.fatdog.eu, and post here on LQ.

Hi! Good that you're using Slackware ARM on the RPi4. Absolutely wonderful combination. Isn't it? You've certainly done yourself [and the RPi4] a great service!

Thanks for your thanks. I just think it's so cool that Slackware runs exceptionally well on any device and all gratitude to Patrick, the Slackware Team, and especially MoZes for the ARM port.

Best advice I can offer is to keep the damned Rpi4 cool. Sure, it still runs OK at 80'C without any additional cooling but is anything between 10-40% slower as a result. Slackware ARM doesn't care and just does what you ask of it without any problems but the RPi4 is not nearly as accommodating. LOL!

NB: I wasted enough time attempting to harness the thermal issues on the RPi4 [it's like trying to juggle with sunshine] and just went and bought one of these: https://imgur.com/NStOcEa - Ice Tower SKU: EP-0107

I have run Slackware ARM on the RPi4 4GB a few times now (strictly weekend hobby/project for now), did some post-installation optimizations (including some of your ideas - thanks again), and ran a couple of updates that went smoothly.

Yes, I find Slackware and RPi4 a great combination - it has run very well for me. I've run into a couple of minor snags, but actually doing stuff is a priority for me over fixing minor issues.

I found your article on RPi4 operating temperatures and cooling before I bought my Pi (so thanks again, again), so I bought my Pi, heat sinks and fan together. No overheating problems here.

Next project, someday: get the Arduino IDE installed so I can work on RPi-Arduino projects directly on the Pi (for now doing this on Slackware64 14.2.) I first have to learn how to build a Slackware package, and then to build a Slackware ARM package.

Great! That's precisely why I made the RPi4 cooling guide/article - so users, such as yourself, might benefit from it. Happy that it's been of some help to you. VERY happy you weren't subject to the same BS I went through over this issue.

I remember a time when I was struggling to learn and understand Slackware packages. There's a PDF document written by MoZes which pretty much taught me all I needed to know. I've had zero questions and no problems whatsoever after assimilating it's contents. It's priceless information.

Related to the high temperature of the Pi4, you should try the latest Raspberry Firmware:
https://www.raspberrypi.org/blog/the...aspberry-pi-4/

It appears that with this latest firmware release you won't be able to fry eggs anymore on the board, but only boil them ...

Why?

One of the first things I did, but from what I understand, it isn’t enough to avoid high temps and throttling for the most demanding usage.

Whether I ever push it so hard or not, I took precautions.

Before updating firmware - even before even putting power to it the first time - I installed heat sinks and a fan. And I set the Pi on its side. And I installed the heat sinks so with the Pi in that position, the heat sink fins are vertical.

I think mine is fine, but I’ll monitor it.

Hi,

on -current, i don't get v3d/vc4 to work on my rpi4/2G ram.

This sould be something like "GL_RENDERER = Gallium 0.4 on VC4", according to https://wiki.gentoo.org/wiki/Raspberry_Pi_VC4

Any advice?

I could improve it a bit, by recompiling mesa with "kmsro" added to the gallium drivers.
GL_RENDERER ist still llvmpipe, but glxgears changed from ~250 FPS to ~320 FPS.

Found out about it here https://intestinate.com/pilfs/beyond.html#wayland

Somebody here with working v3d/vc4 with -current on rpi4?

I solved this by
-deleting /etc/X11/xorg.conf.d/xorg.conf (which had set fbturbo, don't know where this did come from)
-set dtoverlay=vc4-fkms-v3d and hdmi_safe=1 in /boot/config.txt. hdmi_safe maybe because i'm using a hdmi->vga adapter.


Next problem: Firefox and Thunderbird are segfaulting. Seamonkey starts, but crashes on youtube.

Mesa in -current already has that gallum driver btw.
