This installs a silent breakpoint on the do_init_module function. The
breakpoint handler will try to load symbols from the module files found
during lx-symbols execution. This way, breakpoints can be set to module
initialization functions, and there is no need to explicitly call
lx-symbols after
This pokes into the log buffer of the debugged kernel, dumping it to the
gdb console. Helping in case the target should or can no longer execute
dmesg itself.

Parse the target endianness from the output of show endian and cache
the result to return it via the new helper get_target_endiannes. We will
need it for reading integers from buffers that contain target memory.

This helper probes the type of the gdb server. Supported are QEMU and
KGDB so far. Knowledge about the gdb server is required e.g. to retrieve
the current CPU or current task.

Add the internal helper get_module_by_name to obtain the module
structure corresponding to the given name. Also export this service as a

I agree with your patches so far, and I'd suggest we go even further: I'd

Why is that? It doesn't seem to make much sense to
This provides the basic infrastructure to load kernel-specific python
helper scripts when debugging the kernel in gdb.
The loading mechanism is based on gdb loading for objfile-gdb.py when
opening objfile. Therefore, this places a corresponding link to the
main helper script into the output

OK, I've ensured that the hw_breakpoint (from perf) can work
with kprobes (from ftrace) at the same address on x86.
So if arm64 already support hw_breakpoint on perf, kprobes should
work with it.
Single-stepping on x86 is different to the step

zsmalloc encodes a handle using the pfn and an object

at 0x0 the pfn can be 0. This causes the encoded handle to be
