<kazinsal> can't vMotion between different SoCs but this is pretty neat overall

<geist> Was wondering if they were ever going to release that
<geist> I saw it like 2 or 3 years ago at an arm conference thing
<geist> But i think they’ve just been screwing with it on the side waiting for a market to appear
<clever> geist: i saw something about how the new vector stuff in arm, will take a more of a repeat count, rather then being a hard-coded lane width, and then future versions of the cpu can do the same operation in fewer cycles, taking advantage of a wider hw vector unit
<clever> geist: what are your thoughts on arm becoming less RISC'y?

chirag has joined #osdev
<chirag> Haha, I guess so
<chirag> I spent the day figuring out this IRC thing....
<Bitweasil> What's to figure out? Join. Lurk. Discuss.
<Bitweasil> Set up a bouncer so you don't constantly join/part spam the channel.
<HeTo> Bitweasil: wait until you learn about other countries and how the EU had DST end over a week ago already
<chirag> What is a bouncer?
chirag is now known as chir4gm
<gog> it's the guy at the door of the channel that checks if you have an osdev license
<chir4gm> What is a simple bouncer to use?
<chir4gm> Bitweasil: Thanks for the protip!

<geist> 'geist'
<geist> yah that's my general issue with the discord osdev community
<geist> it is set up nicely, mostly, though ti's fairly x86 centric
<geist> but then there's poeple with offensive names, and dick jokes, and etc etc
<geist> about the time i get comfortable with it i'm reminded how low brow it is sometimes
<geist> not that we dont do that here from time to time
<zid> cocks
<geist> and of course that's their prerogative, but it's just not my bag
<zid> There tends to be two kind of styles for places
<zid> either srs and has pros
<zid> or casual and has casual people
<geist> yah i think we try to bridge the gap by being srs when it needs to but casual but down to a specific level
<geist> ie, we generally dont tolerate racist, etc stuff
srjek has joined #osdev
srjek|home has joined #osdev
<gog> the person that posted the dick meme in the learning channel did get banned fwiw lol

<Geertiebear> geist: i mean, we do not tolerate racist stuff either, or any discriminatory stuff for that matter
zaquest has quit [Ping timeout: 264 seconds]
<Geertiebear> and wrt. casual vs pro, I think the "style" of messages is definitely different, but I don't think that correlates to skill level at all
<Geertiebear> there are plenty of people on the osdev discord with very high osdev knowledge, and authors of pretty notable projects on there
<zid> and others who wouldn't touch it with 40 foot pole
<zid> personal tolerance level still factors in
<Geertiebear> of course
<Geertiebear> I'm not trying to say one is better than the other ofc, just nuancing a bit more

<ZetItUp> https://www.youtube.com/watch?v=QAliMv5_DWI pretty interesting if someone is interested with debugging your rasp pi code in windows

<zid> Imagine calling yourself a rockstar/boss/whatever unironically
<ZetItUp> i hate when i start to think like "Is it even worth it" when doing osdev
<ZetItUp> but on the other hand, i think i have taught myself more by doing it, than doing anything else so
<gog> same
<ZetItUp> also looking at how other people are handling the same problem is pretty interesting :D
<geist> Geertiebear: yeah i understand. it's a style thing
<Geertiebear> yeah absolutely

<Bitweasil> Uh...
<Bitweasil> Wait, scroll lock now has an impact on your processor scheduling?
<Bitweasil> Sure, why not.
<Bitweasil> It's 2021, it's a brave new world!
<zid> I am assuming it's SMI driven
<GeDaMo> Scroll lock disables some of the cores, I think
<zid> aren't you glad the ME can sniff your keyboard now bitches? :P
<zid> unplug your cpu cores via keyboard hotkey
<geist> it'd have to be more involved with the os at least
<geist> since widows would need to know to stop scheduling on the cores
<zid> windows might just support cpu hotplug now?
<geist> i'd want a proper turbo button
<geist> with a little LED counter of the number of cores
<geist> like press button and it goes from 24 to 16
<zid> Get a dual core alder lake, then your scroll lock is your core count indexed from 0
<zid> You could actually do that on my mobo geist
<zid> It has 2x 7 segment LED blocks on it
<geist> see there you go
<zid> port 0x80 or whatever for POST codes?
<geist> side note i actually bought one of those bios 7 segment boards recently
<geist> kinda neat
<geist> yah
<zid> Idk how you do port writes in windows though
<geist> alas it's PCI and ISA only, not sure anyone has made a PCIe post board
<zid> probably some drivers
<bslsk05> ​www.highrez.co.uk <no title>
<zid> hmm what do I do with a .lib file
<kazinsal> link it in and pray it works
<zid> The former part
<zid> is not a thing I can do
<zid> open it in IDA, dump the function I intend to call? :p
<kazinsal> objcopy it to a format you can link in, link it in, and pray it works
<zid> oh I can just dlopen the dll

<junon> what in fresh hell is this scroll lock nonsense?
<zid> alder lake has
<junon> I thought I got rid of my packard bell years ago
<zid> good cores, and super shit 'efficient' cores
<kazinsal> too many video game DRM systems use the most atrocious code known to man and explode on alder lake because of the efficiency cores
<zid> there's a bios hack to disable the 'efficient' cores to stop games getting scheduled onto them

<Bitweasil> I've been reading up on the Alder Lake stuff out of curiosity, and it does look promising, especially with DDR5 performance boosts.
<Bitweasil> But then I realize that I literally don't need compute performance for anything.
