Does linux 3 have less bloat and maybe no meltdown et al mitigations?
Any benefit to running Linux 3.x/4.x over 5?
Carter Young
Wyatt Wright
more security vulnerabilities, so faster intel speed
Landon Jackson
>no meltdown et al mitigations
do you want indian advertisers getting root on your system with javascript on web pages and using it to mine bitcoin under a rootkit? no? then fix those vulnerabilities or buy a more carefully designed processor
Brody Allen

Nathaniel Taylor
Pretty much every longterm kernel release should have the most critical intel vulnerability fixes backported.
My advice? JUST FUCKING DISABLE THE MITIGATIONS ON THE KERNEL COMMAND LINE IT'S NOT LIKE WE HAVEN'T ADDED THESE INTO THE KERNEL FOR FUCKNUGGETS LIKE YOU
Alexander Hernandez
Uh I usually browse with no javascript and CSS.
What's the most complete list of paramaters to disable these mitigations?
Matthew Rivera
GRUB_CMDLINE_LINUX="... noibrs noibpb nopti nospectre_v1 nospectre_v2 l1tf=off nospec_store_bypass_disable no_stf_barrier mds=off mitigations=off"
don't forget to grub2-mkconfig or whatever
Elijah Rivera
Try:
pti=off spectre_v2=off l1tf=off mds=off nospec_store_bypass_disable no_stf_barrier
If you're running 5.0 or newer I think you can just add:
mitigations=off
Evan Torres
3.x is just old.
4.x LTS has a fair tradeoff between extra sanity checks and newness.
Levi Robinson
>...
Huh?
Thanks.
>mitigations=off
LOL based.
Cooper Long
So many people requested an easier way to disable all the performance hitting shit for network-isolated devices that they added that one toggle.
Xavier Allen
does turning off mitigations pose any real security threats for a linux running on desktops?
Hunter Wood
Unless you're running any web accessible services I wouldn't worry about it.
Also, don't let your browser run in the background for long periods of time on shifty websites. If you don't run adblock, I'm sorry for your loss.
Eli Carter
hmm I guess I will be safe since I have ublock with every filter enabled
thx
Dylan Cruz
What's grub2-mkonfig for if I have update-grub2?
Evan Howard
People think these vulns are for browsers. Some bastard lied like that. No, they are global, you can execute meltdown/spectre with a native C app if you wanted. Your device drivers could pose an attack.
Hudson Rodriguez
Good lord... I thought my flags to set up VFIO on client Skylake was esoteric. That command line makes it look like my cpu has more errata than it does features.
Brayden Evans
>That command line makes it look like my cpu has more errata than it does features.
this should be Intel's new tagline
Parker Gonzalez
fug my arse didn't know about mitigations=off
gonna disconnect this old shitbox for gaming now
Christian Gray
You need linux 5.2 for that.
kernel.ubuntu.com
Get for amd64 linux-headers-5.2.0-050200rc2_5.2.0-050200rc2.201905262130_all.deb and the three lowlatency .debs
sudo dpkg -i *.deb
Boom.
Alexander Bennett
Though this may break your nvidia proprietary drivers if you have them. Fine for AMD/intel.
Lucas Johnson
yeah isn't so simple but, i'll read up on it
i've got kernel 4 on now so downgrading to 3 or 2 maybe less hassle
intel p4 915 chipset
Chase Diaz
fpbp
Nolan Price
Stick to the longterm 3. You should compile linux yourself once and for all to be quite honest.
Here, grab the same lowlatency setup for an older 3.x
kernel.ubuntu.com
Boot into it from grub, download the longerm 3.16 tarball
cdn.kernel.org
Inside, sudo make oldconfig
That sets up the linux you'll be building to best match your current setup (stable 3.x). If any prompts come up either read them or hold enter for the best default option. Then
sudo make; sudo make modules_install; sudo make install; sudo update-grub2
Boom. Boot into it and delete the older linux packages from /boot/ and run sudo update-grub2 again.
GG you just compiled linux without being a foot smelling gentoofag. If you want to be even more pedantic, replace the -O2 in the Makefile in the tarballs root folder with -Os since the p4 has no cache, before making.
Daniel Martin
yeah 3.16 looks like a good match for old stable wine. thanks user
Landon Scott
>replace the -O2 in the Makefile in the tarballs root folder with -Os
There's literally a CONFIG_CC_OPTIMIZE_FOR_SIZE config for that, just use that. make menuconfig is an idiot proof way to change that it's in General setup-> Compiler optimization level. t. foot smelling gentoofag
Aiden Mitchell
I don't trust config file macros.
Henry Cox
Could you turn on your trip so your nonsense gets filtered
Carter Martin
Did it work? Post results.
Adrian Martinez
No, and there's no reason to run such ancient kernels.
The only thing you're going to get are worse performance and old bugs that never got fixed because LTS kernels only get the most critical fixes.
If you want less blat, compile your own kernel with only the necessary stuff compiled in.
Nathan Martin
>older = less bloat
What the fuck am I reading?
Owen Sanders
Linux 3 contains much, much less code and simpler code at that. Androids run linux 3.
Samuel Anderson
What most of Jow Forums thinks is true.
Charles Thompson
boomer logic
a year from now there's going to be a thread about the right phases of Moon during which to compile your kernel for best performance
The absolute majority of that code is drivers which never even get loaded on your specific HW configuration, you fucking retard.
Cargo cultists and magical thinkers begone from my Jow Forums!

Surprise, phones are not pcs.
Lets forget that older software was written with older computers in mind so it would bottleneck itself on your new ass rig. Remember the decade when linux wasted an entire core on dual core systems due to poor scheduling?
Ryan Rogers
>never even get loaded on your specific HW configuration, you fucking retard.
Have you ever so much as looked at the difference between 3 and 5?
Angel Sullivan
>older software was written with older computers in mind
It's longterm support. Meaning, it's every bit as up to date as 5.
Carter Allen
LTS means security and critical fixes only.
Adrian Stewart
The only reason I see to run an older kernel is if upgrading is hard or impossible.
Chase Allen
What more do you need?
Jonathan Jackson
welp i'm on 4.19 -LTS on arch because of a an ayyymdgpu lmao suspend hang regression. 1 step forward, 2 steps back

>it's every bit as up to date as 5
except it isn't
only the most critical bugs get fixed for LTS releases
hope you're not using XFS because the on-disk format went through a few incompatible updates
that's just one example of the kind of breaking changes you can expect
Adrian Reyes

Josiah Price
No you will lose performance.
Use mitigations=off
Angel Price
I literally compiled linux 3 for half the time I compiled linux 5. The graphical configurator was pleasantly empty regarding bloat like virtual memory and I/O debugging. Nothing wrong with linux 3.
You don't need virutal memory, you don't need heap randomization, or multi-CPU setups, I/O schedulers or any of that trash.
Hudson Wood
>You don't need virtual memory
so you're actually retarded
good to know
Nicholas Sanders
>I'm a deadbeat with 2GB RAM
Stop dragging technology back.
Landon Garcia
>Any benefit to running Linux 3.x/4.x over 5?
it supports more ancient hardware
>Does linux 3 have less bloat and maybe no meltdown et al mitigations?
i do not know what you mean by "bloat" but it has less driver code than current linux
