Kernel 4.6 a worthy one

[floreado]

The problem with switching to the backported kernel is that the user then has to keep track of kernel updates in order to protect against security vulnerabilities and with the jessie-backports kernel any new features may introduce regressions that degrade functionality on your machine.

This problem does not occur with the stable kernel and hardware support should be guaranteed throughout the lifecyle of the release.

EDIT: Please don't take @bester69's posts too seriously, that user can be considered the "court jester" of these boards

@Head_on_a_Stick

I'll take your advice.
It's pointless to look for problem which doesn't exist as you noticed.

Another reason I backport Liquorix kernels is that they enable staging drivers, mostly for wifi, where the Debian backported kernels don't. This again is almost all for newer hardware.

Anyway, I just sent up the sources for the latest Liquorix to the OBS, which means the kernels won't be in that repo until they are built. This version backports some patches for Skylake multimonitor support.

Hi Seteve,
I installed 4.6.4 from

deb http://mxrepo.com/mx/testrepo/ mx15 test

Im testing it; at the moment, I dont feel almost difference between 4.6.3bpo and 4.6.4 MX bpo liqurorix, just a litle bit more responsive liquorix. I probably stay with this up to next one come up.

Thanks,

Hi Steve,

Do i need zswap?

I got message zswap failed to load, i added to grub

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash zswap.zpool=zsmalloc"

update-grub

I checked
dmesg | grep zswap

[ 0.000000] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.6-4.dmz.1-liquorix-amd64 root=UUID=13f8cacf-27d1-43f0-acc3-6f2b3a7e313d ro initrd=/install/gtk/initrd.gz quiet splash zswap.zpool=zsmalloc
[ 0.855942] zswap: loaded using pool lzo/zsmalloc

Now its loaded, the thing, is that with zswap everithing seems to feel quicker , i've never heard about zswap..

do normal kernel has enabled zswapby default??

[xinu]

do I have zswap installed ? ? ?

Code: Select all

dmesg | grep zswap
[    0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-4.4.10-antix.1-amd64-smp root=UUID=ac123456789xxx ro zswap.zpool=zsmalloc vga=788 quiet

[    1.154198] zswap: loaded using pool lzo/zsmalloc

tia !

[stevepusser]

As far as I know, you have to specifically enable zswap in order to be using it:

Enabling zswap

To enable zswap at runtime, execute the following command:
# echo 1 > /sys/module/zswap/parameters/enabled
To enable zswap permanently, add this to your kernel boot parameters Kernel parameters#Configuration:
zswap.enabled=1

Those kernel commands you already have are just suppressing that annoying boot error message.

You shouldn't see any speedup unless your system uses the swap file a lot.

You need to buy more RAM.

Or move away from KDE...

[GarryRicketson]

No need to "buy" it, you can get more ram for free here:

Indeed, i need more CPU, sadly i cant buy more.. Im OK with 2G RAM

[Head_on_a_Stick]

@wizard10000 -- sorry, that was a cheap shot

@jester69 -- actually 2G should work with KDE, do you know why you are using swap?

New kernels 4.7.2 and 4.8 still keeps raising performance,

my old 2008 laptop extensa 5230 still not reaching obsolescence's gap. Good for Torlvalds

[edbarx]

New kernels 4.7.2 and 4.8 still keeps raising performance

I don't get this. How can a more recent kernel result in better performance?

I remember a few years ago there was a kernel patch that addressed how the scheduler switches between processes that gave better performance. However, this type of patch is not something that occurs with every kernel release.

I suppose new kernels tends to improve graphical and hard disk (ntfs) drivers, they add optimal code from time to time. So, from time to time, some kernel brings small boots in time responses I/O disk. It also might be some times placebo. anyways i still dont feel my computer is coming inside obsolescence gap,

Some examples:
- kde plasma 5 will boots up performance over kde 4.14 ( new Qt5 motor improves speed)
- Chromium came into obsolescence gap since versión 35 in my computer (i freeze chromium in that version)
- Iceweasel came into obsolescence gap since about version 38 in my computer (i still update it as i keep this browser as security one)
- Kernels 4.7.2 and 4.8 still good (my computer still not slowing down with them, i would say they are some quicker than 3.16kernel)

im delighted with kernel 4.8 RC4 (im using ubuntu's kernel), in my user experience everything seems working pretty good with that kernel (very good kernel)

Now im using ubuntu's kenerl to enjoy the last ones, in my user experiences and for my needs i dont see the point in dont use it and this way enjoying last kernels. But if someday someone convince me tha using ububtu's kernel in debian is very bad idea, i will stop doing that unless there isnt risky

i think new stable kernel will be 4.9, i hope they to keep improving..

What will anyone gain by convincing you? It is you who will benefit.

[sunrat]

You can do whatever you want to your system, it's open source. Just make sure you have a full system backup from when it is working. Then you can restore it when it eventually does break.

Yes, what would anyone gain from using a Ubuntu kernel? Do you think that it is better than Debian's kernel? If you can give some rational reason for why the Ubuntu kernel is better for your use case, then it would immediately cause me to wonder why you just don't use Ubuntu to begin with? Or use whatever parts of their .config/patching you need? (see http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8-rc4/) Because if you were to just use Ubuntu instead, and you encountered a problem with something in the future, then you could ask for support at Ubuntu forums. But can you do that if you are using their kernel but have everything else from other distributions? Maybe, probably not.

The official and various unofficial guides on the net to compiling kernels are quite easy to follow. And I wonder what miracles you might be able to do to your "boot time to kde" with some tinkering of the values.
