How to get new kernel ?

Question

Hello! I emerged gentoo-sources to try if my Lenovo G50-30 will not freeze suddenly on it.

I do not know where get config for it. I used config from /usr/src/debian-sources dir - last saved config that I think is workable. Is it right?

It compiled, but there is no new kernel in /boot. What to do after compilatioon?

Genkernel provides a generic configuration that works with gentoo-sources,vanilla-sources.

Verify /usr/src/linux is symlinked to the kernel sources to be built:
eselect kernel list
Available kernel symlink targets:
  [1]   linux-4.4.115 *
  [2]   linux-debian-sources-3.19.3
* is pointing to linux-4.4.115 vanilla sources
ls -la /usr/src/linux
lrwxrwxrwx 1 root root 13 Feb 23 23:37 /usr/src/linux -> linux-4.4.115

Command to build:

genkernel all

Genkernel installs my completed build of linux-4.4.115 to /boot

ls /boot
System.map-debian-sources-x86_64-3.19.3-1~exp1
System.map-genkernel-x86_64-4.4.115
initramfs-debian-sources-x86_64-3.19.3-1~exp1
initramfs-genkernel-x86_64-4.4.115
intel-uc.img
kernel-debian-sources-x86_64-3.19.3-1~exp1
kernel-genkernel-x86_64-4.4.115

After configuring grub I reboot into new kernel:

uname -a 
Linux funtoo 4.4.115 #1 SMP Fri Feb 23 22:06:22 EST 2018 x86_64 Intel(R) Core(TM)2 Duo CPU E4500 @ 2.20GHz GenuineIntel GNU/Linux

As I have never used debian-sources or genkernel, I can't say if you can use a config file from debian-sources as a base for the gentoo sources. What I found after some searching is, that genkernel could write the config file to /etc/kernel. But you probably have to ask someone who used debian-sources and genkernel if thats true. gentoo-sources keeps the config file in the source directory of the kernel as .config or, after installation, in boot:

-rw-r--r-- 1 root root 9610288 23. Feb 08:34 vmlinuz-4.15.5-gentoo

If using a config file from another kernel (like debian-sources) is not possible, you would have to configure the kernel manually, the first time. After that you could use the existing config. Although it seems that you also could use genkernel to compile gentoo-sources.

As for a more useful manual, you could probably have a look at the gentoo pages for that subject: https://wiki.gentoo.org/wiki/Kernel/ru

I think the best way then would be to do it like I do and install it manually (second link). Not sure if you could use your config file from debian sources as base for the gentoo-sources (have never used debian-sources). But the worst that could happen is that you have to the config anew.

okay. How to config kernel when install manually?

The link https://www.funtoo.org/Building_a_Kernel_from_Source says

Copy configurations if you have previous configurations to copy:


# cp /boot/config-3.13.7 .config

What to do if I use gentoo-sources first time? I have no sense which modules I need and will current kernel config help me or not.

Thank you @cardinal! Your advise was simple for reproducing. But one question rested.

I run this

''' my /dev/sda1 does not mount itself
# mount /dev/sda1 /boot
# cd /usr/src
# rm linux
# ln -sf /usr/src/linux-4.15.7-gentoo-r1 /usr/src/linux
# cd /usr/src/linux
# eselect kernel list
Available kernel symlink targets:
  [1]   linux-4.15.7-gentoo-r1
  [2]   linux-debian-sources-4.14.12 *
# eselect kernel set 1
# genkernel --menuconfig all
''' then I load last config from linux-debian-sources-4.14.12 and exit menu
''' it compiled kernel and modules
''' and put into /boot dir newkernel

# boot-update -v

I saw new kernel's line in grub during boot,  gentoo-sources was default. I got error message during start: wpa_supplicant could not started.

I check lsmod and saw Atheros/Qualcom driver was absent. https://bpaste.net/show/a1aaf108a5fd

This manual helped me to setup WLAN driver on Funtoo https://wireless.wiki.kernel.org/en/users/drivers/ath9k

I reconfigured kernel checking new lines:

Quote

Device drivers -> Network devices -> Wireless LAN ->
* Atheros/Qualcomm devices
M Atheros 5xxx wireless cards support
M Atheros 5xxx PCI bus support
M Atheros 802.11n wireless cards support
 * Atheros ath9k PCI/PCIe bus support
M Atheros 802.11ac wireless cards support
 M Atheros ath10k PCI support

I just saw `genkernel --menuconfig all` loading debian-sources config and checked all options I found in the other terminal with `genkernel --menuconfig all` (configuring gentoo-sources).

WLAN works.

But I cannot mount /dev/sda1 and `fdisk -l` looks another

# mount /dev/sda1 /boot
mount: special device /dev/sda1 does not exist

I think I need configure kernel to work with disks? Which options should I enable?

I found my new kernel config lacks lot of options in 'Pseudo filesystems' and all other sections. Completely empty config. How to determine which option I need to mount /dev/sda1 ?

# cat /etc/fstab
...
# <fs>			<mountpoint>	<type>		<opts>		<dump/pass>

/dev/sda1		/boot		ext2		noauto,noatime	1 2
/dev/sda2		none		swap		sw		0 0
/dev/sda3		/		ext4		noatime		0 1
#/dev/cdrom		/mnt/cdrom	auto		noauto,ro	0 0

# mount /dev/sda1 /boot
mount: special device /dev/sda1 does not exist

I get this error when run new kernel  (gentoo-sources) .

I have no such problem in old kernel (debian-sources) .

anything in dmesg that would help to debug, can you paste maybe the whole dmesg somewhere?

ad PS you have to switch locale to change terminal output

did you create or recreate the partition now?

maybe a reboot is needed or use partprobe from sys-block/parted to re-read the partition table.

partprobe -s

no, i am not creating partition. but I used tool from systemrescuecd to restore partitions cause in last installation I needed to save data on disk and clicked accidentally to mkfs... cannot remember details, but that tool helped to restore partitions and now I am using that partition I had before reinstall. so may be this is causing the problem?

in a qna site i read about raid and dolvm in grub.cfg. I rebooted to debian-sources to get access to /dev/sda1. if it is useful here my grub.cfg that I did not touch:

# cat /boot/grub/grub.cfg
set timeout=3

  insmod part_msdos
  insmod ext2
  set root=(hostdisk//dev/sda,msdos1)
  search --no-floppy --fs-uuid --set 47173c48-55db-4ef0-9803-91bf2303baf6
if loadfont /grub/unifont.pf2; then
   set gfxmode=text
   insmod all_video
   terminal_output gfxterm
fi

set menu_color_normal=cyan/blue
set menu_color_highlight=blue/cyan

menuentry "Funtoo Linux genkernel - kernel-genkernel-x86_64-4.15.7-gentoo-r1" {
