Let me several questions about kernel compilation?
Hello! I use trisquel 8.0. I have no sense how to compile kernel, I tried once it worked on 1 laptop, the other laptop stops and does not compile every time. Please, what is wrong in these actions:
# apt-get update
# apt-get upgrade
# apt-get install dpkg-dev libncurses5-dev kernel-package fakeroot bzip2 build-essential

Then I loaded config from /boot/config-4.4.0-119-generic, switched off that I do not need: IRDA и Bluetooth then saved config into /home/user/kernel/mybuild/.config

Sorry? Why does it stop?
Is it a kernel bug or my own mistake?
"Segmentation fault" is an important message there. I don't know what the rests says because they're in Russian and I only speak English.
I notice you're building 4.13 but using a .config from 4.4. There will be configuration file differences that need to be accounted for. Run make oldconfig first to answer the questions. You can also use mine for 4.13 if you'd rather: https://jxself.org/git/?p=kernel-configs.git
Also, instead of 'make' try 'make bindeb-pkg' - Then you'll get .deb files that can be used with the package manager.
jxself, thank you.
make menuconfig
make oldconfig
make
cause the same error: segmentation faul. Ur config for 4.13 forced me to answer several questions. I only pressed enter. So the error rests - Segmentation fault.
which GCC version are you using?
It seems that the /home/y/kernel/linux-hwe-4.13.0/scripts/ubuntu-retpoline-extract-one script does something wrong. Why don't you better fo everything manually?
Thank you for reply.

manually? I am using linux-libre, cause it is free. I cannot remove everything non-free from kernel.org releases. So that script you show is default linux-libre script.
... I downloaded linux-source-4.4.0 and started `make menuconfig && make` . I did not use my current config. Just rested things as they were and also disabled bluetooth and irda. Now it is making for 20 minutes. (Making of 4.13 stopped after 4 minutes). There are warnings but it does not stop, warnings like this:
linux-4.4.0/mm/compaction.c:1398:2: warning: enumeration value ‘COMPACT_INACTIVE’ not handled in switch [-Wswitch]
I think config for 4.4 cannot work for 4.13.
Why there is no anywhere info about how to get config for upstream version ? I thought kernel has no any configuration set and I tried to use my current config.
What do you mean by "it does not stop"? Compiling Linux (especially without using make's "jobs" option) takes time. And, yes, Linux's compilation rises many warnings (it is "normal").
"I thought kernel has no any configuration set and I tried to use my current config."
The kernel does need to be configured: This is the time where you get to decide exactly what parts of the kernel should be built and how they should work. Like what scheduler do you want to use? https://en.wikipedia.org/wiki/Scheduling_(computing)#Since_Linux_2.6.23
And there's lots more too.
Further, that config varies from one major release to another (so a config for 4.4 will be different from 4.13 because each new release introduces new and changed features, so the config must be updated to cover the differences. This is what "make oldconfig" is for: Taking a config from an old version and updating it based on whatever version you're building.) The kernel config will also vary from one CPU architecture to another (so a config for 32-bit x86 will be different from 64-bit and will be different from ARM and MIPS and RISC-V...) Not only because they are different CPUs but also because some kernel features are only relevant on certain kinds of machines. You can explore all of the options when doing "make nconfig" but there's also lots of information online too. Configuring the kernel is a topic of much discussion.
make stops with fatal error, I achieve nothing.
Please, where can I find kernel build log? I 've leaved pc on 'make' execution, after that it was switched off due to os error. I want to understand if make was finished or not
What error? If it is a segmentation error, it may be a hardware issue. I would check the RAM with "memtest86+" (in Trisquel's repository, to be launched from the bootloader; let it run a whole night).
Sorry. Why 1 laptop trisquel 8 has only one linux-source, but other - 4 ones.

Why so different results ? Where is linux-source-4.13.0 on my first laptop??
Check your sources.list. They don't seem to be identical.
Hello! I tried to compile linux-source-4.4.0 without any changes, resting config as it was there.
# make menuconfig
...without any changes I saved .config
# make
it worked ok. So now I try again to make with no bluetooth and no irda.
Every time I have difficult to understand why Xen, Android, Fujitsu, Miscrosoft Hyper-V and many other stuff are there. When I switching off all I see as unnecessary the make breaks. `make` takes 10 hours for my asus x552e.
Some configurations are indeed incorrect. As I already wrote, you want to use make's "jobs" (-j) option. For instance:
$ make -j 5
The more cores you have, the highest the argument can be (in it a number of source files compiled in parallel).

Well, you can see the difference right? As you compare line by line they're not identical: One has Flidas Main and Security. The other has Flidas Main, Security, and Updates.
ok. I see it.
When I do not touch config `make` finishes ok. But now I switched off IrDa, Bluetooth, Xen drivers, Hyper-V, Fujitsu, all wifi manufacturers except my Atheros. And make failed with this:

Please, teach me how disable unnecessary stuff knowing definitely make will not stop.
Your config mentions 4.4.128 so I first try with mainline Linux-libre:
wget https://linux-libre.fsfla.org/pub/linux-libre/releases/4.4.128-gnu/linux-libre-4.4.128-gnu.tar.xz
tar xf linux-libre-4.4.128-gnu.tar.xz
cd linux-libre-4.4.128
wget http://termbin.com/ef1w
mv ef1w .config
make oldconfig
make -j4 bindeb-pkg
And it builds.
Then I try Trisquel's modified version of Linux-libre:
apt-get source linux-source-4.4.0
cd linux-4.4.0
wget http://termbin.com/ef1w
mv ef1w .config
make oldconfig
make -j4 bindeb-pkg
And that fails:
ERROR: "hci_register_dev" [ubuntu/rsi/ven_rsi_91x.ko] undefined!
ERROR: "hci_recv_frame" [ubuntu/rsi/ven_rsi_91x.ko] undefined!
ERROR: "hci_unregister_dev" [ubuntu/rsi/ven_rsi_91x.ko] undefined!

So it's specific to Trisquel. I recommend to file a bug over it. In the meantime you can build mainline Linux-libre just fine, so there's your workaround. Although you may want to upgrade to the current version in the 4.4 series which is 4.4.138. But it's up to you of course.
jxself, thanks a lot!
I have compiled last Libre-linux and successfully boot into it. I used only menuconfig and disabled bluetooth, ipv6, xen, all wifi modules except my atheros.
But the kernel boot time becomes twice bigger than I had on 4.4.0
Now I have:

But I had on 4.4.0 this:

$ cat /boot/config-4.4.0-128-generic | nc termbin.com 9999
http://termbin.com/rf1q
and I had bluetooth errors on boot.

I think boot time depends on components that are enabled in 4.17.3 kernel.
Please, let me know how to optimize kernel in my situation?
"Please, let me know how to optimize kernel in my situation?"
You could try build a kernel with make localyesconfig or make localmodconfig which will only include the module currently loaded on your system (so make sure all modules you need are presently loaded or they won't be available in the new kernel.) But that will probably only help with compile time by not building stuff you don't need and with the size of the kernel since those won't be there. I don't expect it to make much of a difference in start up time.
I tried completely to disable all options in linux-libre-4.17.3-gnu kernel and compile it. I installed kernel and modules and then booted to iniramfs, so my system works not proper way on it.
I need to delete safely new broken kernels. How to do this?
