Dgdb_kernel.md5 Starting with Android U it is possible to attach a gdb to the guest kernel, when
29 The [kernel documentation](
30 https://www.kernel.org/doc/html/latest/dev-tools/gdb-kernel-debugging.html) has
31 some general techniques on how to debug kernel with gdb.
35 If you are debugging Microdroid kernel that you have built [locally](
36 ../../microdroid/kernel/README.md), then look for `out/dist/vmlinux` in your
37 kernel repository.
39 If you are debugging Microdroid kernel bundled with the `com.android.virt` APEX,
40 then you need to obtain the build ID of this kernel. You can do this by
42 `packages/modules/Virtualization/microdroid/kernel/arm64` or

Dramdump.md3 A debuggable Microdroid VM creates a RAM dump of itself when the kernel panics. This
8 RAM dump is created automatically when there's a kernel panic. However, for
18 crashdump kernel is executed.
32 [ 14.998693][ T148] Starting crashdump kernel...
47 reboot: Restarting system with command 'kernel panic'
82 You also need the image of the kernel binary with debuggin enabled. The kernel
83 binary should be the same as the actual kernel that you used in the Microdroid
84 VM that crashed. To identify which kernel it was, look for the kernel version
94 of the kernel.
99 DON'T forget to replace `9013362` with the actual build ID of the kernel you used.

Dtracing.md5 Starting with android14-5.15 kernel it is possible to get traces from the hypervisor.
9 The user space hypervisor tracing interface is located either at /sys/kernel/tracing/hyp or at
10 /sys/kernel/debug/tracing/hyp. On the Android phones it will usually be /sys/kernel/tracing/hyp,
11 while on QEMU it will be /sys/kernel/debug/tracing/hyp.
