[gentoo-user] How to manage load on the GPU?

[tuxic]

Hi,

sorry for the somehow vague subject line...no native speaker...

With Blender I do a lot of experimenting and tinkering which
involves rendering most of the time.

With rendering comes ... waiting for the result.

Often (I am trying to) watch videos, like tutorial about
what I currently trying to acchieve with Blender.

The problem is, that the video (the audio does not) stutters
in short periods. 

Interestingly it does this not every time but quite often.

And it only effects videos online.

mpv for example is not affected.

Is there any way to configure whatever it is in a way, that Online
videos can be played smoothlessly also?

Hardware:
AMD Ryzen 5 3600
MSI Ventus RTX 2060 SUPER (NVidia)
32 GB RAM

Any helpful idea is very appreciated!
Cheers!
Meino

Generally a person installs from some sort of Linux bootable device, CD,
DVD, USB stick or something.  If everything works as it should, the
easiest way I know to get a list of drivers, lspci -k should work.  If
you want to narrow down to the drivers themselves, you can do it like this:


root@fireball / # lspci -k | grep driver
    Kernel driver in use: pcieport
    Kernel driver in use: pcieport
    Kernel driver in use: pcieport
    Kernel driver in use: ahci
    Kernel driver in use: ohci-pci
    Kernel driver in use: ehci-pci
    Kernel driver in use: ohci-pci
    Kernel driver in use: ehci-pci
    Kernel driver in use: piix4_smbus
    Kernel driver in use: snd_hda_intel
    Kernel driver in use: ohci-pci
    Kernel driver in use: pcieport
    Kernel driver in use: ohci-pci
    Kernel driver in use: ehci-pci
    Kernel driver in use: k10temp
    Kernel driver in use: fam15h_power
    Kernel driver in use: nvidia
    Kernel driver in use: snd_hda_intel
    Kernel driver in use: xhci_hcd
    Kernel driver in use: r8169
    Kernel driver in use: dmfe
    Kernel driver in use: ahci
root@fireball / #


At that point, you can use those names to search for the driver and
enable them.  That's the way I've done it in the past and it gives you a
very high chance of a working kernel for all hardware.  If you want to
see what each driver drives, just leave off the grep part.

Hope that helps.

Sorry if I'm misunderstanding you here, but it seems like [1] might be of  help,
providing you can access the details of your connected devices with `lspci`  and
`lsusb`.

For example, if I wanted to set up my Ethernet card, I would run

$ `lspci | grep -i ethernet`
00:19.0 Ethernet controller: Intel Corporation Ethernet Connection (2)
I218-V (rev 05)

and then use "Intel" (vendor) and "I218-V" (name) at [1] to find that  I  needed
to  enable  CONFIG_E1000E,  CONFIG_ETHERNET,  and  CONFIG_NET_VENDOR_INTEL  [2].

Hi Raphael,

I have a good manual for kernel config.
I saved the website of 'Firas Khalil Khana' called 'dotslashlinux'

I can send it to you via mail.

Please tell me.

Please file bugs to bugs.gentoo.org and maintainer should help you.

In this case it looks like a https://bugs.gentoo.org/722042 which

[gentoo-user] Kernel drivers and modules list

[Raphael MD]

Hello everyone,

I’ve booted my system with a gentoo live cd, just to figure out my system
drivers and modules to configure the kernel, because it’s difficult to
realize what drive my intel Ethernet card uses and many others.

Are there  some command to extract that list to configure the kernel?

In fact, are there some manual to help to configure the kernel in the best
way?

 Usually I configure my Zen processor, put my schedule, and set preemptive
kernel to low latency and put out every other drive.

Thanks!

Here is one of mine: its part of openrc -  if you don't have it you
might be using systemd which should have something similar.

Re: [gentoo-user] Kernel config for Docker

[Victor Ivanov]

Andrew makes a good point that, of course, not all options will be
relevant to a particular image or use case. The script is aimed to check
for "full" compatibility. Having some reported as missing is by no means
a deal breaker.

Re nftables it's a very valid point as well. I too use nftables instead
of iptables and, in general, anything that dares touch my rules I will
either disable the option for it to do so or, if that's not possible,
swiftly eradicate it off my system with vengeance. I'm not a big fan of
how Docker manages netfilter rules so I too tend to disable that from
the config and, as Andrew said, it has been slow at adopting nftables.
It seems Docker is being developed with primary consideration for stable
(read archaic) distributions that have long release cycles.

If you use nftables at all - even via other software such as firewalld,
etc - Docker may or may not like that. Previously, though admitedly
quite a while ago, Docker just loved adding iptables rules in addition
to my nftables rules. Needless to say, that quickly became a mess.

nftables is _a lot_ easier to manage, even writing rules manually feels
a lot more intuitive. So I think the learning curve (at least in terms
of syntax) tends to be less steep IMO if you decide to go down that road
at some point.

Anyway, this probably wasn't a post of high contribution value haha

Keep us updated in case you encounter any issues!

Re: [gentoo-user] Realtek r8169 realtek.ko not loaded.

[Victor Ivanov]

Hi Alexander,

A while back I had the exact same issue with a remote machine that I am
managing. It has an Asus B45-M mobo with an r8169 chipset. Ever since
the 5.2.x kernel family - where it last used to work - it has been a pain.

Initially I added a manual "soft" dependency in "/etc/conf.d/modules" as
William has suggested to you with "realtek" appearing first in the list.
But this stopped working following an update to 5.4.x and is still the
case today with the 5.6.x family (I keep testing it once in a while).

I then decided to build both realtek and r8169 modules into the kernel:

REALTEK_PHY=y
CONFIG_R8169=y

It did require a bit of faff as the whole chain of dependencies from
REALTEK_PHY had to be built in as well, but I think that was about 5-6
kernel options in total.

Adding it to the ramdisk as William suggests might work too. In my case
I didn't bother trying this due to the fact that every failed attempted
required manual intervention by someone to get the machine booted with
working kernel.

I have a gut feeling that tells me adding it to the initrd probably
won't work. But if you're planning on trying it, please keep us posted.
I would be very interested in hearing your solution.

Regards,
V

I'm still pretty much in the dark about setting up nftables and iptables in 
the kernel config. Not to worry, though; I dare say it'll become clearer in 
time.

Re: [gentoo-user] Realtek r8169 realtek.ko not loaded.

[William Kenworthy]

Easiest would be to put it in /etc/conf.d/modules and rebuild the
initrd.  Genkernel picks it up from there.  You could also ask genkernel
to add all built modules to the initrd via its config file.

[gentoo-user] Realtek r8169 realtek.ko not loaded.

[Alexander Puchmayr]

Hi there

I just upgraded an older notebook with r8169 network chip to new kernel 5.4 
(sys-kernel/gentoo-sources-5.4.28) with genkernel. 
After booting the new kernel the network adapter was not initialized, no 
network interface eth0.
Dmesg says
[6.390973] r8169 :08:00.0: realtek.ko not loaded, maybe it needs to be 
added to initramfs?
[6.392864] r8169: probe of :08:00.0 failed with error -2

After searching with google I found a thread in the kernel mailing list
https://bugzilla.kernel.org/show_bug.cgi?id=204343
The cause is a soft depencency to module realtek.ko, which needs to be loaded 
first.

Doing this manually, i.e. rmmod r8169 && modprobe realtek && modprobe r8169 
works fine; network interface eth0 gets configured and is operating.

Since the kernel loads the network module before systemd is running, it has to 
be configured in initrd somehow.
So, the final question is, how to get that into initrd with genkernel?
I need to add something like this

cat /etc/modprobe.d/realtek 
Softdep r8169 pre: realtek

How do I get this into initrd with genkernel-next?

Thanks in advance
Alex
