Where is kernel source directory Ubuntu?

How do I see all the kernel modules installed on Linux?
You need to use lsmod program which show the status of loaded modules in the Linux Kernel. Linux kernel use a term modules for all hardware device drivers. Please note hat lsmod is a trivial program which nicely formats the contents of the /proc/modules , showing what kernel modules are currently loaded.
How do I find my Linux kernel path?
You can use uname -r to find out the version you’re running and then look for a file in /boot with that name. You can also use cat /proc/cmdline to find the kernel path, but note that this path is relative to the root image at boot time, so / likely means /boot/ in the running system.
Where is Linux kernel directory?
Where is kernel located in Linux?
Where is the Linux Kernel located? Since the Linux kernel is a piece of code, it must be stored somewhere on the file-system, such that every time the system reboots, the kernel is loaded in the memory. In Debian/Ubuntu systems, the Linux kernel can be found within the /boot directory.
How do I create a Linux kernel?

How do I add a module to a Linux kernel?
Loading a Module
- To load a kernel module, run modprobe module_name as root .
- By default, modprobe attempts to load the module from /lib/modules/kernel_version/kernel/drivers/ .
- Some modules have dependencies, which are other kernel modules that must be loaded before the module in question can be loaded.
Is it possible to build a kernel module in Ubuntu?
Instructions to build a kernel module in Ubuntu are already available, but the patch for ch341 driver is for Linux 3.18.6, and Ubuntu 14.04 comes with Linux 3.13. So I had two choices:

The kernel dir is /lib/modules/$ (uname -r)/build. (The uname -r defines the installed kernel details.) Don’t alter uname -r with anything. It will automatically place the kernel version for the command.
What are the different types of kernel build guides?
Kernel/BuildYourOwnKernel – Minimalist kernel build guide KernelDevelopmentShift – New development model. KernelGitGuide – Using the git repos.
