|
|||
3. Use ``set architecture i8086`` to dump 16 bit code. Then use
|
||||
``x/10i $cs*16+$eip`` to dump the code at the PC position.

Advanced debugging options:
|
||||
Debugging multicore machines
|
||||
============================
|
||||
|
||||
GDB's abstraction for debugging targets with multiple possible
|
||||
parallel flows of execution is a two layer one: it supports multiple
|
||||
"inferiors", each of which can have multiple "threads". When the QEMU
|
||||
machine has more than one CPU, QEMU exposes each CPU cluster as a
|
||||
separate "inferior", where each CPU within the cluster is a separate
|
||||
"thread". Most QEMU machine types have identical CPUs, so there is a
|
||||
single cluster which has all the CPUs in it. A few machine types are
|
||||
heterogenous and have multiple clusters: for example the ``sifive_u``
|
||||
machine has a cluster with one E51 core and a second cluster with four
|
||||
U54 cores. Here the E51 is the only thread in the first inferior, and
|
||||
the U54 cores are all threads in the second inferior.
|
||||
|
||||
When you connect gdb to the gdbstub, it will automatically
|
||||
connect to the first inferior; you can display the CPUs in this
|
||||
cluster using the gdb ``info thread`` command, and switch between
|
||||
them using gdb's usual thread-management commands.
|
||||
|
||||
For multi-cluster machines, unfortunately gdb does not by default
|
||||
handle multiple inferiors, and so you have to explicitly connect
|
||||
to them. First, you must connect with the ``extended-remote``
|
||||
protocol, not ``remote``::
|
||||
|
||||
(gdb) target extended-remote localhost:1234
|
||||
|
||||
Once connected, gdb will have a single inferior, for the
|
||||
first cluster. You need to create inferiors for the other
|
||||
clusters and attach to them, like this::
|
||||
|
||||
(gdb) add-inferior
|
||||
Added inferior 2
|
||||
(gdb) inferior 2
|
||||
[Switching to inferior 2 [<null>] (<noexec>)]
|
||||
(gdb) attach 2
|
||||
Attaching to process 2
|
||||
warning: No executable has been specified and target does not support
|
||||
determining executable automatically. Try using the "file" command.
|
||||
0x00000000 in ?? ()
|
||||
|
||||
Once you've done this, ``info threads`` will show CPUs in
|
||||
all the clusters you have attached to::
|
||||
|
||||
(gdb) info threads
|
||||
Id Target Id Frame
|
||||
1.1 Thread 1.1 (cortex-m33-arm-cpu cpu [running]) 0x00000000 in ?? ()
|
||||
* 2.1 Thread 2.2 (cortex-m33-arm-cpu cpu [halted ]) 0x00000000 in ?? ()
|
||||
|
||||
You probably also want to set gdb to ``schedule-multiple`` mode,
|
||||
so that when you tell gdb to ``continue`` it resumes all CPUs,
|
||||
not just those in the cluster you are currently working on::
|
||||
|
||||
(gdb) set schedule-multiple on
