When we have a problem syncing CP registers between kvm<->qemu it's a

This enables the saving and restoring of machine state by including the

At that point we can prefix the cmpxchg
TCG ops with our new tcg_dmb barrier.
Without the LOCK prefix we still guarantee an atomic update but without
any explicit synchronisation between the cores.
In practice Linux at least uses LOCK prefixed cmpxchg instructions in
its synchronisation code.
x86 code will still emit s/m/lfence instructions to ensure external
devices see memory accesses in the right order. These should certainly
cause memory barriers tcg ops to be emitted.

Positional? Really. You can only have one command at a time.
run Invoke docker run and take care of cleaning up
buildBuild docker image out of a dockerfile
cleanClean up docker instances
optional arguments:
-h, --help show this help message and exit
OK that's useful, but do we have args for build?

Hmm same result. We have to call like this:

Make qemu_log_mask() a macro which only calls the function to
do the actual work if the logging is enabled. This avoids making
a function call in possible fast paths where logging is disabled.

ely flush TBs if no vCPUs are currently
executing in those regions. But I suspect that is a much more complex
future optimisation.
Having said that is it safe to flush TBs from a given page if we know
no vCPUs are currently executing in that page? As the execution loop has
to exit the chained TBs as we cross page boundaries we could just keep
account of which vCPUs are currently in which page.

Be
warnings being kicked out of the compiler
though. On the VM "make check" fails at ... but as the build was
broken beforehand I can't tell if this is a regression. It passes fine
on my Linux box.
Alex Bennée (2):
cpus: don't use atomic_read for vm_clock_warp_start
include/qemu
As vm_clock_warp_start is a 64 bit value this causes problems for the
compiler trying to come up with a suitable atomic operation on 32 bit
hosts. Because the variable is protected by vm_clock_seqlock, we check its
value inside a seqlock critical section.
