log out... log back in... toast notification daemon is eating a whole core... it's failing to create an IPC endpoint... because, even after years of this subsystem existing, I never implemented a close method for the server side, so the last toast daemon's endpoint still exists and the attempt to reuse the same handle is failing...

works fairly well. since you can only pass them around to eventually routines that are designed to copyin/copyout

(re-asking) Hi, is the Minix book a good next step after learning the basics of C and x86 asm?
<anon16_>
Or should I improve my knowledge on other topics beforehand?
<dzwdz>
i haven't done the minix book myself, but i think that you could just learn as you go

I was little bit rude to sw security engineers in my country as well, cause any real techman knowing modern computers would tell google project zero enthusiasts just to fuck off beautifully not wasting others and my time really, this is madness complete brainwash there is way more intelligent TCP hack to do it always for the rest of the time, to compromise everything, I am entirely sure that linus turning mad over this shit would say the exact thing to
<sesame2>
you. So this was the formal response before as well as today and will be in the future too. it is total idioticy it is not a lie but broken attempt or approach entirely.
sesame2 was kicked from #osdev by geist [sesame2]

ooooh got one again
<geist>
[70335.529445] Uhhuh. NMI received for unknown reason 31 on CPU 12.
<geist>
[70335.529446] Do you have a strange power saving mode enabled?
<geist>
[70335.529446] Dazed and confused, but trying to continue
<geist>
thats on my ryzen home server box
diamondbond has joined #osdev
<zid>
Have you considered not getting a ryzen and having it deliver bizzare NMIs
<geist>
well when intel makes something that fits the bill, sure
<zid>
You don't want a quad core from 2011!?
<geist>
neing
<geist>
nein
<kazinsal>
yeah if intel shits out a 4.4+ GHz 12C/24T that doesn't cost four digits I'd buy one
<zid>
still the best cpus intel have made lol
<geist>
aaaand ECC, that was the main reason i finally upgraded my server from a reliable old dual socket nehalem from 2009
anon16_ has quit [Ping timeout: 265 seconds]
<geist>
it wasn't cheap to get ECC on anything in the intel world since about nehalem, since you'd have to buy a xeon to do it
<zid>
I have ecc but can't find the ram, I need weird stuff, unregistered 800MHz+ dimm x4
<zid>
$30 a dimm just to get ecc is.. spendy
anon16_ has joined #osdev
<kazinsal>
a 5950X 16C/32T is nine hundred bucks canadian, which is an absolutely insanely good price for that much oomph
<geist>
oh indeed. the 64GB of ECC i have in this one is not cheap (or fast)
<zid>
Regular ram is like $10 a dimm
<zid>
and my ram was all out of people's desk drawers for free
<geist>
uh. $10?
<zid>
yep, just double checked on ebay
<geist>
for something obsolete i'm sure
<geist>
so yes. of course you can buy a 10 year old former server class thing
<zid>
ddr3, ddr4's only better if you run both dual channel
<zid>
which I'm not
<geist>
in fact thats precisely what i upgraded from (a 12 year old former server class thing)
<zid>
11900k makes me genuinely upset to look at
<geist>
wanted more ram (64GB) and more cores (8c16t)
<kazinsal>
yeah, in 2021 people generally want to be upgrading from soething from 2011
<zid>
their 'best' desktop cpu is lower memory BW, lower max capacity, lower pci-e bandwidth
<geist>
yeah
<zid>
20 entire lanes, you get to pick if you have a gpu or an ssd to go with your ethernet card
diamondbond has quit [Quit: Leaving]
<geist>
yeah though honestly i think people worry about pci lanes a lot more than they should
<kazinsal>
yeah
<kazinsal>
especially in the GPU world
<geist>
for desktop class stuff dedicate a few for your gpu and then move on. it wont really matter except exotic benchmarks and/or very specialized cases
<zid>
the PLX/QLX I forget the name chips are /expensive/
<zid>
they add a lot of cost to the mobo and they're basically mandatory
<kazinsal>
the difference between 4.0 8x and 4.0 16x for even the top of the top end of GPUs is margin of error
<zid>
If they gave me a bunch of 4x slots I'd probably be fine on 4.0 y ea
<zid>
but they don't, they give you a 16x slot and some plexed lanes
<geist>
yah i remember anandtech or whatnot did a benchmark of some gpu on the other side of a thunderbolt link (and thus 4x i think)
<geist>
and it was not half bad. 80%+
<geist>
not that it'd recommend it but really most of the processing is within the card
zaquest has quit [Quit: Leaving]
<zid>
There's probably *a* game you will notice it on because it does a shit load of just in time texture streaming, but you're not going to notice it otherwise
<geist>
so it might become texture bound in certain situations
<geist>
yah
<zid>
I'll keep my 40 boring lanes with my two 16 slots and the rest split over ether/sata
<kazinsal>
the issue with the upcoming big bastard of the 12XXX series from Intel is that they still cap out at 8 big cores with up to an additional eight little cores
<geist>
OTOH if i spend lots of monies on my GFX card i wanna get the most out of it, within reason
<zid>
Intel's just doing what intel does, not releasing good chips because they're waiting for their next process node to finally work
zaquest has joined #osdev
<zid>
then they'll be able to make faster chips that still sell, and still won't give you nice shit like ecc/quad/lanes
<zid>
repeat
<zid>
The year is 2042, intel still haven't gotten 7nm fabs working, cpus now have 4 pci-e lanes and 1 memory channel
<kazinsal>
honestly the thing I'm expecting out of intel in the next 18 months is the Xe stuff to kick Nvidia and Radeon in the ass
<kazinsal>
especially considering they've already shown off a platform-agnostic temporal upscaling solution that's probably 85-90% the effective quality of DLSS 2.0
<kazinsal>
but it doesn't need tensor cores etc.
<zid>
Intel needs to show something or I'll start losing faith on whether they still 'have it'
<zid>
Starting to feel like they've turned into one of those huge corporate machines that can't do anything good
Matt|home has quit [Remote host closed the connection]
<geist>
Yeah,I don’t want them to fail per se, but it is nice to see some competition again
<geist>
It does make me feel somewhat good to know that standard high end cpu design knowledge appears to no longer be centered just at one or two companies
<zid>
I'm not even sure it's really competition, I just think intel missed their dates, and amd released 'server' features for desktop while intel was napping
<geist>
But yeah just about now is when intel should start getting competitive again so AMD and whatnot doesn’t get slack
<zid>
they came out with, granted, very good perf, but the main draws were more cores than intel were offering, with ecc, and lots of lanes
<zid>
intel hasn't even flinched in what they're offering for desktop
<geist>
Well the zen core was really a major jump for AMD at least. Though i guess you could read it as the bulldozer was just a failure
<zid>
They stole a march, essentially
<zid>
They did good work, but it was only competitive because intel fell 5 years behind their own roadmaps
<kazinsal>
turns out once you get Jim Keller in for a couple years you suddenly make billions of dollars again
<geist>
Yeah. Nice interview with him in anandtech last month or so
