Re: [Trisquel-users] Let me several questions about kernel compilation?
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 safely delete new broken kernels. How to do this?
# dpkg -l | grep linux-image | awk '{print$2}'
linux-image-4.4.0-119-generic
linux-image-extra-4.4.0-119-generic
linux-image-generic
# ls /boot
abi-4.4.0-119-generic retpoline-4.4.0-119-generic

# ls /lib/modules/
4.17.3-gnu 4.4.0-119-generic 4.4.15-gnu
--
Please, how delete 4.17.3-gnu, vmlinuz-4.17.3-gnu.old ?? will my pc boot
correctly after
# rm -rf vmlinuz-4.17* System.map-4.17* config-4.17* initrd.img-4.17.3-gnu
/lib/modules/4.17.3-gnu
# update-grub
# reboot

Or it needs something else?
Re: [Trisquel-users] Let me several questions about kernel compilation?
"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.
Re: [Trisquel-users] Let me several questions about kernel compilation?
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 then I had on 4.4.0 Now I have: $ uname -a Linux asus 4.17.3-gnu #1 SMP Wed Jun 27 21:09:44 +03 2018 x86_64 x86_64 x86_64 GNU/Linux $ systemd-analyze Startup finished in 35.301s (kernel) + 1min 38.982s (userspace) = 2min 14.284s $ cat /home/user/kernel/mybuild/.config | nc termbin.com http://termbin.com/xer0 $ dmesg [ 23.880080] usb 5-2: new full-speed USB device number 2 using xhci_hcd [ 23.952630] ACPI: Video Device [VGA] (multi-head: yes rom: no post: no) [ 23.989023] 3ACPI BIOS Error (bug): Could not resolve [^^^PB2.VGA.AFN7], AE_NOT_FOUND (20180313/psargs-330) [ 23.989054] ACPI Error: Method parse/execution failed \_SB.PCI0.VGA.LCDD._BCM, AE_NOT_FOUND (20180313/psparse-516) [ 23.991492] ACPI Error: Evaluating _BCM failed (20180313/video-364) [ 23.993303] input: Video Bus as /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/LNXVIDEO:00/input/input9 But I had on 4.4.0 this: $ systemd-analyze Startup finished in 11.933s (kernel) + 5.280s (userspace) = 17.214s $ cat /boot/config-4.4.0-128-generic | nc termbin.com 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?
Re: [Trisquel-users] Let me several questions about kernel compilation?
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! ERROR: "hci_alloc_dev" [ubuntu/rsi/ven_rsi_91x.ko] undefined!

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.
Re: [Trisquel-users] Let me several questions about kernel compilation?
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.

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.

Re: [Trisquel-users] Let me several questions about kernel compilation?
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.
Re: [Trisquel-users] Let me several questions about kernel compilation?
Check your sources.list. They don't seem to be identical.
Re: [Trisquel-users] Let me several questions about kernel compilation?
"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. 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.
Re: [Trisquel-users] Let me several questions about kernel compilation?
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

So what exactly I need? How to compile 4.13? Can I not to use current config? So will I need setup kernel options or there are default options that will work? ... I downloaded linux-source-4.4.0 and started `make menuconfig && make` . I did not use my current config. Just rested things as it was and also disabled bluetooth and irda. Now it is making 15 minutes. (Making of 4.13 stopped after 4 minutes). 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 configurations set and I tried to use my current config.
Re: [Trisquel-users] Let me several questions about kernel compilation?
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?
Re: [Trisquel-users] Let me several questions about kernel compilation?
which GCC version are you using?
Re: [Trisquel-users] Let me several questions about kernel compilation?
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.
Re: [Trisquel-users] Let me several questions about kernel compilation?
"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.
