Looks like everything is almost done :D but there is still room for improvement

For example, video encoding drivers are missing

I know this will be a very broad and random question, but do any of you experts know if something pertaining to clocks and timers changed between kernel 5.8 and 5.9? That driver I reverse engineered works fine on 5.8 kernels, but looks a bit weird on 5.9... A user reported that changing CPU governor to performance helped (on our particular device)
<LordKalma>
but others couldn't verify that. Something weird is going on...
<apritzel>
LordKalma: how easily and reliably can your reproduce it? Have you thought about bisecting that?
<LordKalma>
I have. The thought of doing that is daunting, but we'll have to haha
<LordKalma>
A member using build root could see the problem, another building armbian with the driver patched in also sees the problem.Text looks weird, bit as if pixelated, some yellowish borders on things... Neofetch has those color boxes in the bottom and they are as if unaligned, its weird
<LordKalma>
I don't have a good picture, I think, but let me see here
<apritzel>
I understand that bisecting sounds daunting, but actually it's straightforward, once you wrapped your head around it
<apritzel>
and it's very powerful (if you have a clear regression), since you don't need to guess or make assumptions or dig into code
<apritzel>
you just follow the procedure
<apritzel>
just one advice: don't go to lunch in the middle of it, or you will forget where you were ;-)
<apritzel>
or you write down exactly in which state you left ;-)
vagrantc has quit [Quit: leaving]
<LordKalma>
Hahah yeah, I'd do it with a spreadsheet
<LordKalma>
but where does this come from, how do you actually choose what to put in a defconfig? (for example)
<apritzel>
well, this is too embedded for my taste ;-)
<LordKalma>
hahah Linux from scratch kinda person? :D
<apritzel>
I made the DTS because it's the only actual complicated thing you need, the rest is bog standard Allwinner A33
<apritzel>
LFS: not really
<apritzel>
the A33 is well supported in the kernel and U-Boot, so all you need is the DT to describe your *board*
<apritzel>
the rest is off-the-shelf Linux/U-Boot
<apritzel>
you just need a distro that supports ARMv7
<apritzel>
so I like to split things up: there is U-Boot(firmware), the kernel, userland
<apritzel>
in your case you probably need some special userland, because that contains the actual radio app and the right tools for the UI (those rotary encode knobs, for instance)
<LordKalma>
yes, but for testing it's okay the radio doesn't radio :D
<apritzel>
yeah, the actual radio is for people without imagination, I guess :-D
<LordKalma>
I bought it for the radioing aspect of it
<LordKalma>
only after I discovered everybody was "hacking" it
