4 years agohw/intc/arm_gic: add tracepoints
Hollis Blanchard [Thu, 21 Apr 2016 15:24:41 +0000 (08:24 -0700)] 
hw/intc/arm_gic: add tracepoints

These are obviously critical to understanding interrupt delivery:
gic_enable_irq
gic_disable_irq
gic_set_irq (inbound irq from device models)
gic_update_set_irq (outbound irq to CPU)
gic_acknowledge_irq

The only one that I think might raise eyebrows is gic_update_bestirq, but I've
(sadly) debugged problems that ended up being caused by unexpected priorities.
Knowing that the GIC has an irq ready, but doesn't deliver to the CPU due to
priority, has also proven important.

4 years agotcg: Rework tb_invalidated_flag
Sergey Fedorov [Wed, 13 Apr 2016 19:40:18 +0000 (22:40 +0300)] 
tcg: Rework tb_invalidated_flag

'tb_invalidated_flag' was meant to catch two events:
 * some TB has been invalidated by tb_phys_invalidate();
 * the whole translation buffer has been flushed by tb_flush().

Then it was checked:
 * in cpu_exec() to ensure that the last executed TB can be safely
   linked to directly call the next one;
 * in cpu_exec_nocache() to decide if the original TB should be provided
   for further possible invalidation along with the temporarily
   generated TB.

It is always safe to patch an invalidated TB since it is not going to be
used anyway. It is also safe to call tb_phys_invalidate() for an already
invalidated TB. Thus, setting this flag in tb_phys_invalidate() is
simply unnecessary. Moreover, it can prevent from pretty proper linking
of TBs, if any arbitrary TB has been invalidated. So just don't touch it
in tb_phys_invalidate().

If this flag is only used to catch whether tb_flush() has been called
then rename it to 'tb_flushed'. Declare it as 'bool' and stick to using
only 'true' and 'false' to set its value. Also, instead of setting it in
tb_gen_code(), just after tb_flush() has been called, do it right inside
of tb_flush().

In cpu_exec(), this flag is used to track if tb_flush() has been called
and have made 'next_tb' (a reference to the last executed TB) invalid
for linking it to directly call the next TB. tb_flush() can be called
during the CPU execution loop from tb_gen_code(), during TB execution or
by another thread while 'tb_lock' is released. Catch for translation
buffer flush reliably by resetting this flag once before first TB lookup
and each time we find it set before trying to add a direct jump. Don't
touch in in tb_find_physical().

Each vCPU has its own execution loop in multithreaded mode and thus
should have its own copy of the flag to be able to reset it with its own
'next_tb' and don't affect any other vCPU execution thread. So make this
flag per-vCPU and move it to CPUState.

In cpu_exec_nocache(), we only need to check if tb_flush() has been
called from tb_gen_code() called by cpu_exec_nocache() itself. To do
this reliably, preserve the old value of the flag, reset it before
calling tb_gen_code(), check afterwards, and combine the saved value
back to the flag.

This patch is based on the patch "tcg: move tb_invalidated_flag to
CPUState" from Paolo Bonzini <pbonzini@redhat.com>.

The value returned from tcg_qemu_tb_exec() is the value passed to the

attempted to execute. It is a little confusing to store it in a variable

reason, correspondingly. This simplifies the code and improves its
readability.
