Re: Using Pi as Desktop, how to manage RAM?

I ran my Pi3 as my only PC for 18 months with no major issues. Never had a problem with dtparam=sd_overclock=100 for my 64G Evo+ - are you sure yours is genuine? Must be threads here that I have posted in test result numbers. Especially random small file writes. Personally I preferred to keep the US...

Re: Opensuse and overlays.

Now is there a similar way to set up the hardware on opensuse and how so. I am having a hard time understanding the resources needed to perform the task. Morning - welcome to openSUSE! openSUSE does things on a Pi the same way as Raspbian via config.txt and the device tree. So in theory the mechani...

Re: RPi3 on aarch64-CPU freq scaling and temp sensors broken

So the question now is why doesn't it work with a current kernel? Yup, $1m! I am struggling to find the OpenSuSE bods who know - despite using SuSE on my desktop for 15+ years the Pi3/aarch64 skills are well hidden, probably embedded deep in the SLE offices somewhere. They clearly had the ability t...

Re: RPi3 on aarch64-CPU freq scaling and temp sensors broken

... so the original question remains unanswered: how can one get temp and cpu scaling under aarch64? The 4.4.49 aarch64 kernel in OpenSUSE LEAP 42.2 does things fine, available here. My top tip if installing as per their instructions here: after the xzcat | dd remove the card from your machine, rei...

Re: Status of CPU freq scaling on RPi3 running aarch64?

darksky wrote:...so is this in fact an upstream kernel bug?
The subtleties of what is kernel/upstream/downstream etc or Foundation/Raspbian hacked are beyond me. But it does seem odd to me as well that >=4.8 kernels, which are supposed to have better Pi3 CPU support, seem to lack some basics.

Re: Status of CPU freq scaling on RPi3 running aarch64?

I believe this is a kernel issue: oddly enough 4.4 aarch64 kernel in opensuse LEAP 42 has decent support (on demand & performance as well as temp) whereas 4.9 aarch64 kernel in tumbleweed has nothing as per your Arch 4.10 experience. Also (for opensuse aarch64) 4.4 LEAP has WiFi support whereas 4.9 ...
