Change the kernel version as appropriate In GDB console, attach to the VM: targetremote :1234 (?) Load main kernel symbols: lx-symbols fakeroot debian/rules clean binary-headers binary-generic binary-perarch Set the source path: setsubstitute-path /build/linux-HSAA8v/linux-4.4.0/ . The ...
The options are documented in the Linux kernel source, under Documentation/sysctl/kernel.txt. To make the core_pattern permanent, and survive reboots, you can set it via "kernel.core_pattern" in /etc/sysctl.conf. Trying again: # ./cachetop.py Segmentation fault (core dumped) # ls -lh ...
Build the Linux kernel by running the following commands: make make modules Copy the kernel to your Windows machine. E.g. you can do it by running creating a new Windows shared folder (e.g. 'share') and a new Windows user (e.g. virtual) and then mounting it from the Linux machine:...
-s tells QEMU to start a GDB server on port 1234 (it’s equivalent to -gdb tcp::1234). -S can be appended to pause the VM before starting to run. Optional configurations Serial console With serial console, you can follow the guest b...
Once you have built the kernel but not installed it yet, it's a good time to make a VirtualBox snapshot. If anything goes wrong, you will be able to restore the snapshot later.Install the new kernel on the Linux machine: sudo make modules_install sudo make install...
Once the kernel command line is correctly set, there are two ways you can connect to GDB: If the CONFIG_KDB* macros are enabled in tegra_defconfig, the kernel waits for KGDB during boot. It opens a terminal window showing the KDB console and displays these messages: [ 2.368148] c...
Because the default STM32MP1 kernel is built without tracing support, VisualKernel’s module that allows tracing loading/unloading of other modules without parsing the full kernel symbols won’t work out-of-the-box. Hence selectObtain module information via: Parsing kernel structures. ...
Made explicitly for debugging Windows kernel-mode components is the kernel debugger (KD). NTKD is a debugger for Windows NT operating systems that operates in kernel mode. A command-line debugger that offers a simple debugging interface is the console debugger (CDB). ...

# debuginfo-install --downloadonly kernel-3.10.0-327.el7 This should download two files in the current directory on the host for later extraction and use by GDB. Copy these files from the guest to the host for the host GDB to use them. I choose~/kernel-debug/as a sane location for th...
