Linux Device Driver learning-kernel Compilation

Linux Kernel version 3.2.0 (uname-r can be viewed)
Ubuntu version 10.04 (view method http://www.bkjia.com/ OS /201203/122509.html)

Download the kernel version at http://www.kernel.org/
Decompress to a path, I decompress to/usr/src, any path should be OK, the folder name is linux-3.2
# Linux-3.2/cd/usr/src/
You can use make menuconfig, make xconfig, and other commands to configure the kernel. For more information, see http://lamp.linux.gov.cn/linux/kernel_options.html.
Compile the kernel
# Make
It may take several hours
Installation module and Kernel
# Make modules_install
# Make install
Update grub
Two methods
# Grub_mkconfig
Or
# Update-grub
Then, check the startup items in/boot/grub. cfg, which is about 60 rows.
I added the following content:
Menuentry 'ubuntu, Linux 3.2.0 '-- class Ubuntu -- class gnu-linux -- class gnu -- class OS {
Recordfail
Insmod ext2
Set root = '(hd0, 3 )'
Search -- no-floppy -- fs-uuid -- set 6f9dd836-7461-4b59-84ca-eff8707297e1
Linux/boot/vmlinuz-3.2.0 root =/dev/sda3 ro quiet splash
}
Menuentry 'ubuntu, Linux 3.2.0 (recovery mode) '-- class Ubuntu -- class gnu-linux -- class gnu -- class OS {
Recordfail
Insmod ext2
Set root = '(hd0, 3 )'
Search -- no-floppy -- fs-uuid -- set 6f9dd836-7461-4b59-84ca-eff8707297e1
Echo 'Load Linux ...'
Linux/boot/vmlinuz-3.2.0 root =/dev/sda3 ro single
Echo 'Load the boot virtual disk ...'
}
Restart the computer and select this option to enter the newly compiled kernel.
It seems very simple, and I have been worried about it for several days. I did not know whether grub was to be updated. If I had a command, I went to the file myself. I copied a copy and modified it. It should have been wrong, each time I select the kernel, It is a kernel panic. I once suspected that there was a problem when I configured the kernel and compiled it countless times ....
Thanks to zjc and gmy for their help.
