Search - "kernel dump"
Me, hacking the sunxi kernel to access gpio on my orange pi:
My friend: "oh, a raspberry, are you using python for that?"
Me, looking up from opcode dump: "you can use python for this?"3
//Proper Haxk20 tech rant
So uhmmm this is interesting.
Apparently Acer decided to not make proper vBIOS for Nitro 5 RX560X and they left some stuff well just empty or to stock.
For example they set the maximum OC clocks to stock so even if you want to overclock you cant exactly on Linux.
OK but why can we OC on windows ?
Well to no ones suprise windows stuff doesnt exactly follow specs published and well they just ignore some stuff so if you want you can OC on windows even past the max OC clocks because oh safety on windows isnt a fucking thing.
OK so how do we fix it on Linux ?
Well we have 2 ways.
1. Is to dump vBIOS. Edit it to contain the proper max limit and load it on startup because flashing it isnt great to do on laptop.
This will get you OC support but takes ages because again this isnt normal GPU. Its desktop GPU in laptop and Acer had to do something to it because oh well. So you will get lot of shit in the way.
Second way you can OC is to lets just say disable the security feature on Linux.
Hmmmm but AMDGPU driver doesnt exactly support that.
What do we do ?
Well if you look at AMDGPU code there is code for overdrive which is basically driver for overclocking support. When you look at the code for it you will be blown away first at what you are looking at but then Oh boom. variables for max clock on memory and core. Bingo.
OK set it to the values and boot the patched kernel. Hmmmmmm why is it so slow ?
Why is it running at minimum clocks ?
Look at the code again and you forgot that drivers use Hz instead of MHz. Yeahhhhhh. OK multiply the value to match Hz and its at stock. But no worries. Now when i tell the GPU to run at clocks past its limit it wont yell at me that i cant do that.
OK now comes a little weird part. I didnt find docs about boot parameters in linux and i didnt find a way to implement them. So if anybody has a way of implementing them please comment here a link to it. I will possibly even make this a patch and send it to kernel since well manual patching is shit.2

TLDR; WINE+me=system binaries gone. (HOWTHEFUCKDIDIDOTHAT) Kernel panic. Core program files gone. I'll never have it fixed right. Will backup, then install fedora tomorrow.
I really like games and I'm sure there are many of you who can relate. Imagine my perpetual pain, being on the job hunt, no money, and only my Linux laptop for games. (It's only Linux because of a stupid accident and a missing windows installation disk, partly explained in a previous rant). My stack of games my dad and I have played over the years, going back to populous and before, looked light enough for my laptop to run them smoothly. I wanted to see if I could get one to work. My eyes settled on simcity 4 and Sid Meier's railroad tycoon, 13 and 10 years old, respectively. Simcity didn't work as many times as I tried following online instructions. Disk 1 went fine. Disk 2 showed up as Disk 1. Didn't think much of it, so long as the computer could read the contents. I downloaded playonlinux as that could apparently do the complex stuff for me. Didn't work. I gave up with it after an hour and a half.
Next was railroads. Put the disk in aaaand it says SimCity disk 1 is in the tray. Fuck right off, thank you very much. Eject, put back, reject, eject, fiddle in wineconfig, eject, more of this, and voilà it read as railroads :) Ran autoplay.exe with wine, followed instructions, installed it, and it worked! Chose single player, then the map and setting, pressed play, and all the models of the buildings and track were floating in the air over a green plane, the UI is weird and the map doesn't represent anything but trains. All the fkin land is gone, laying track is gonna be a ballache.
I quit it and decided bedtime.
sudo shutdown -h now
shutdown not found.
reboot not found
Nope, I don't like this.
Force choked my laptop by the power button. Turned it on again.
Lines of text appear.
Saw a phrase I've only ever seen on Mr Robot.
Nooooo thanks, not today, this is fiction.
I turned it off and on. Same thing. I read the logs and some init files couldn't be found. I got the memory stick I used to install mint in the first place and booted from that. I checked the difference between my stick's bin and sbin and the laptop's, and it was indeed missing binaries. Fuck knows what else has happened, I only wanted to play games but now I don't know what is or isn't in my computer. How can I trust what's on it now?
I go downstairs and tell my dad. He says something about rpm, but this is Linux so it won't work. I learn that binaries can be copied over, so maybe I can fix it.
Go upstairs again, decide not to fix it. Fedora is light, has a good rep for security, and is even more difficult to get games on, which is my vice. There are more reasons, but the overriding one is that I'm spooked by the fact that something I did went into and removed system binaries, maybe even altered others, so I want something I'm less likely to do that with. Also my fellow cs students used to hate on it but my dad uses and recommended it so I want to try it.
Also, seriously, fuck wine/PlayOnLinux/my inability to follow instructions(?)/whatever demons haunt me. Take your pick, at least one if not more is to blame and I can't tell which, but it's prooooobably the third one.
It's going to be 16 hours before I touch my laptop again, comments before I backup then install fedora are welcome, especially if they persuade me to do differently.
P.S thanks for reading this mind dump of a post, I'm writing while it's fresh but I'm tired AF.6
Starting to wonder why I tend to like our QA people so much: they often seem so much saner. Yes, sometimes they quibble as with the complaints about a page that is hidden from the user anyway, but they would usually not creep to deep into the hole creating most unintuitive workflows and abysmal logic.
Disclaimer: We're more like backend devs, but we had to do a UI which was beautifully slaughtered by the CEO messing with it - guess what's happening with the new one - and because of that... thing I already nearly smashed my Mac because stupid entered credentials for updating software would only be applied if you defocused once out of the password entry box. Fucked up stuff like this, which devs meddle with, give up, just shrug it off and dump it on the (l)user.
Or a more recent example: So PM wanted a stupid "Apply to all" buttons on a list that can be filtered. Guess to which items the actions should be applied if you filtered it and you currently only see a small selection in your window! Yes, of course it still applies to all items in the universe. QA guy who's just trying the buttons comes to me: "Hey, you sure this "apply all"-stuff supposed to work like that?"
Third example to end this long QA-praise: So there is this virtual appliance we build and we should support another stupid hypervisor.. and he found the kernel modules I have to activate additionally so we can just convert the existing image without having to create a new build system.3
