This patch set generalizes the already existing solution for
printing NMI messages. The main idea comes from Peter Zijlstra.
v4 adds one more patch that flushes NNI buffers when the system
is panicing. Otherwise, it is almost the same as the last version
in the -mm tree, see changes below for more
printk() takes some locks and could not be used a safe way in NMI context.
The chance of a deadlock is real especially when printing stacks from all
CPUs. This particular problem has been addressed on x86 by the commit
a9edc8809328 ("x86/nmi: Perform a safe NMI stack trace on all CPUs").
The pat
NMIs could happen at any time. This patch makes sure that the safe
printk() in NMI will schedule IRQ work only when the related structs are
initialized.
All pending messages are flushed when the IRQ work is being initialized.

We could not resize the temporary buffer in NMI context. Let's warn if a
message is lost.
This is rather theoretical. printk() should not be used in NMI. The only
sensible use is when we want to print backtrace from all CPUs. The
current buffer should be enough for this purpose.
[a...@linux-f
Testing has shown that the backtrace sometimes does not fit into the 4kB
temporary buffer that is used in NMI context. The warnings are gone when
I double the temporary buffer size.
This patch doubles the buffer size and makes it configurable.
Note that this problem existed even in the x86-speci
In NMI context, printk() messages are stored into per-CPU buffers to avoid
a possible deadlock. They are normally flushed to the main ring buffer via
an IRQ work. But the work is never called when the system calls panic() in
the very same NMI handler.
This patch tries to flush NMI buffers before

Some of the interrupt vectors on 64-bit POWER server processors are
only 32 bytes long (8 instructions), which is not enough for the full
first-level interrupt handler. For these we need to branch to an out-
