+CPUs perform independent memory operations effectively in random order.
+but this can be a problem for CPU-CPU interaction (including interactions
+between QEMU and the guest). Multi-threaded programs use various tools
+to instruct the compiler and the CPU to restrict the order to something
+that is consistent with the expectations of the programmer.
+
+The most basic tool is locking. Mutexes, condition variables and
+semaphores are used in QEMU, and should be the default approach to
+synchronization. Anything else is considerably harder, but it's
+also justified more often than one would like. The two tools that
+are provided by qemu/atomic.h are memory barriers and atomic operations.
+
+Macros defined by qemu/atomic.h fall in three camps:
+
+- compiler barriers: barrier();
+
+- weak atomic access and manual memory barriers: atomic_read(),
+ atomic_set(), smp_rmb(), smp_wmb(), smp_mb(), smp_read_barrier_depends();
+
+- sequentially consistent atomic access: everything else.
+
+
+COMPILER MEMORY BARRIER
+=======================
+
+barrier() prevents the compiler from moving the memory accesses either
+side of it to the other side. The compiler barrier has no direct effect
+on the CPU, which may then reorder things however it wishes.
+
+barrier() is mostly used within qemu/atomic.h itself. On some
+architectures, CPU guarantees are strong enough that blocking compiler
+optimizations already ensures the correct order of execution. In this
+case, qemu/atomic.h will reduce stronger memory barriers to simple
+compiler barriers.
+
+Still, barrier() can be useful when writing code that can be interrupted
+by signal handlers.
+
+
+SEQUENTIALLY CONSISTENT ATOMIC ACCESS
+=====================================
+
+Most of the operations in the qemu/atomic.h header ensure *sequential
+consistency*, where "the result of any execution is the same as if the
+operations of all the processors were executed in some sequential order,
+and the operations of each individual processor appear in this sequence
+in the order specified by its program".
+
+qemu/atomic.h provides the following set of atomic read-modify-write
+operations:
+
+ void atomic_inc(ptr)
+ void atomic_dec(ptr)
+ void atomic_add(ptr, val)
+ void atomic_sub(ptr, val)
+ void atomic_and(ptr, val)
+ void atomic_or(ptr, val)
+
+ typeof(*ptr) atomic_fetch_inc(ptr)
+ typeof(*ptr) atomic_fetch_dec(ptr)
+ typeof(*ptr) atomic_fetch_add(ptr, val)
+ typeof(*ptr) atomic_fetch_sub(ptr, val)
+ typeof(*ptr) atomic_fetch_and(ptr, val)
+ typeof(*ptr) atomic_fetch_or(ptr, val)
+ typeof(*ptr) atomic_xchg(ptr, val
+ typeof(*ptr) atomic_cmpxchg(ptr, old, new)
+
+all of which return the old value of *ptr. These operations are
+polymorphic; they operate on any type that is as wide as an int.
+
+Sequentially consistent loads and stores can be done using:
+
+ atomic_fetch_add(ptr, 0) for loads
+ atomic_xchg(ptr, val) for stores
+
+However, they are quite expensive on some platforms, notably POWER and
+ARM. Therefore, qemu/atomic.h provides two primitives with slightly
+weaker constraints:
+
+ typeof(*ptr) atomic_mb_read(ptr)
+ void atomic_mb_set(ptr, val)
+
+The semantics of these primitives map to Java volatile variables,
+and are strongly related to memory barriers as used in the Linux
+kernel (see below).
+
+As long as you use atomic_mb_read and atomic_mb_set, accesses cannot
+be reordered with each other, and it is also not possible to reorder
+"normal" accesses around them.
+
+However, and this is the important difference between
+atomic_mb_read/atomic_mb_set and sequential consistency, it is important
+for both threads to access the same volatile variable. It is not the
+case that everything visible to thread A when it writes volatile field f
+becomes visible to thread B after it reads volatile field g. The store
+and load have to "match" (i.e., be performed on the same volatile
+field) to achieve the right semantics.
+
+
+These operations operate on any type that is as wide as an int or smaller.
+
+
+WEAK ATOMIC ACCESS AND MANUAL MEMORY BARRIERS
+=============================================
+
+Compared to sequentially consistent atomic access, programming with
+weaker consistency models can be considerably more complicated.
+In general, if the algorithm you are writing includes both writes
+and reads on the same side, it is generally simpler to use sequentially
+consistent primitives.
+
+When using this model, variables are accessed with atomic_read() and
+atomic_set(), and restrictions to the ordering of accesses is enforced
+using the smp_rmb(), smp_wmb(), smp_mb() and smp_read_barrier_depends()
+memory barriers.
+
+atomic_read() and atomic_set() prevents the compiler from using
+optimizations that might otherwise optimize accesses out of existence
+on the one hand, or that might create unsolicited accesses on the other.
+In general this should not have any effect, because the same compiler
+barriers are already implied by memory barriers. However, it is useful
+to do so, because it tells readers which variables are shared with
+other threads, and which are local to the current thread or protected
+by other, more mundane means.
+
+Memory barriers control the order of references to shared memory.
+They come in four kinds:
+
+- smp_rmb() guarantees that all the LOAD operations specified before
+ the barrier will appear to happen before all the LOAD operations
+ specified after the barrier with respect to the other components of
+ the system.
+
+ In other words, smp_rmb() puts a partial ordering on loads, but is not
+ required to have any effect on stores.
+
+- smp_wmb() guarantees that all the STORE operations specified before
+ the barrier will appear to happen before all the STORE operations
+ specified after the barrier with respect to the other components of
+ the system.
+
+ In other words, smp_wmb() puts a partial ordering on stores, but is not
+ required to have any effect on loads.
+
+- smp_mb() guarantees that all the LOAD and STORE operations specified
+ before the barrier will appear to happen before all the LOAD and
+ STORE operations specified after the barrier with respect to the other
+ components of the system.
+
+ smp_mb() puts a partial ordering on both loads and stores. It is
+ stronger than both a read and a write memory barrier; it implies both
+ smp_rmb() and smp_wmb(), but it also prevents STOREs coming before the
+ barrier from overtaking LOADs coming after the barrier and vice versa.
+
+- smp_read_barrier_depends() is a weaker kind of read barrier. On
+ most processors, whenever two loads are performed such that the
+ second depends on the result of the first (e.g., the first load
+ retrieves the address to which the second load will be directed),
+ the processor will guarantee that the first LOAD will appear to happen
+ before the second with respect to the other components of the system.
+ However, this is not always true---for example, it was not true on
+ Alpha processors. Whenever this kind of access happens to shared
+ memory (that is not protected by a lock), a read barrier is needed,
+ and smp_read_barrier_depends() can be used instead of smp_rmb().
+
+ Note that the first load really has to have a _data_ dependency and not
+ a control dependency. If the address for the second load is dependent
+ on the first load, but the dependency is through a conditional rather
+ than actually loading the address itself, then it's a _control_
+ dependency and a full read barrier or better is required.
+
+
+This is the set of barriers that is required *between* two atomic_read()
+and atomic_set() operations to achieve sequential consistency:
+
+ | 2nd operation |
+ |-----------------------------------------|
+ 1st operation | (after last) | atomic_read | atomic_set |
+ ---------------+--------------+-------------+------------|
+ (before first) | | none | smp_wmb() |
+ ---------------+--------------+-------------+------------|
+ atomic_read | smp_rmb() | smp_rmb()* | ** |
+ ---------------+--------------+-------------+------------|
+ atomic_set | none | smp_mb()*** | smp_wmb() |
+ ---------------+--------------+-------------+------------|
+
+ * Or smp_read_barrier_depends().
+
+ ** This requires a load-store barrier. How to achieve this varies
+ depending on the machine, but in practice smp_rmb()+smp_wmb()
+ should have the desired effect. For example, on PowerPC the
+ lwsync instruction is a combined load-load, load-store and
+ store-store barrier.
+
+ *** This requires a store-load barrier. On most machines, the only
+ way to achieve this is a full barrier.
+
+
+You can see that the two possible definitions of atomic_mb_read()
+and atomic_mb_set() are the following:
+
+ 1) atomic_mb_read(p) = atomic_read(p); smp_rmb()
+ atomic_mb_set(p, v) = smp_wmb(); atomic_set(p, v); smp_mb()
+
+ 2) atomic_mb_read(p) = smp_mb() atomic_read(p); smp_rmb()
+ atomic_mb_set(p, v) = smp_wmb(); atomic_set(p, v);
+
+Usually the former is used, because smp_mb() is expensive and a program
+normally has more reads than writes. Therefore it makes more sense to
+make atomic_mb_set() the more expensive operation.
+
+There are two common cases in which atomic_mb_read and atomic_mb_set
+generate too many memory barriers, and thus it can be useful to manually
+place barriers instead:
+
+- when a data structure has one thread that is always a writer
+ and one thread that is always a reader, manual placement of
+ memory barriers makes the write side faster. Furthermore,
+ correctness is easy to check for in this case using the "pairing"
+ trick that is explained below:
+
+ thread 1 thread 1
+ ------------------------- ------------------------
+ (other writes)
+ smp_wmb()
+ atomic_mb_set(&a, x) atomic_set(&a, x)
+ smp_wmb()
+ atomic_mb_set(&b, y) atomic_set(&b, y)
+
+ =>
+ thread 2 thread 2
+ ------------------------- ------------------------
+ y = atomic_mb_read(&b) y = atomic_read(&b)
+ smp_rmb()
+ x = atomic_mb_read(&a) x = atomic_read(&a)
+ smp_rmb()
+
+- sometimes, a thread is accessing many variables that are otherwise
+ unrelated to each other (for example because, apart from the current
+ thread, exactly one other thread will read or write each of these
+ variables). In this case, it is possible to "hoist" the implicit
+ barriers provided by atomic_mb_read() and atomic_mb_set() outside
+ a loop. For example, the above definition atomic_mb_read() gives
+ the following transformation:
+
+ n = 0; n = 0;
+ for (i = 0; i < 10; i++) => for (i = 0; i < 10; i++)
+ n += atomic_mb_read(&a[i]); n += atomic_read(&a[i]);
+ smp_rmb();
+
+ Similarly, atomic_mb_set() can be transformed as follows:
+ smp_mb():
+
+ smp_wmb();
+ for (i = 0; i < 10; i++) => for (i = 0; i < 10; i++)
+ atomic_mb_set(&a[i], false); atomic_set(&a[i], false);
+ smp_mb();
+
+
+The two tricks can be combined. In this case, splitting a loop in
+two lets you hoist the barriers out of the loops _and_ eliminate the
+expensive smp_mb():
+
+ smp_wmb();
+ for (i = 0; i < 10; i++) { => for (i = 0; i < 10; i++)
+ atomic_mb_set(&a[i], false); atomic_set(&a[i], false);
+ atomic_mb_set(&b[i], false); smb_wmb();
+ } for (i = 0; i < 10; i++)
+ atomic_set(&a[i], false);
+ smp_mb();
+
+ The other thread can still use atomic_mb_read()/atomic_mb_set()
+
+
+Memory barrier pairing
+----------------------
+
+A useful rule of thumb is that memory barriers should always, or almost
+always, be paired with another barrier. In the case of QEMU, however,
+note that the other barrier may actually be in a driver that runs in
+the guest!
+
+For the purposes of pairing, smp_read_barrier_depends() and smp_rmb()
+both count as read barriers. A read barriers shall pair with a write
+barrier or a full barrier; a write barrier shall pair with a read
+barrier or a full barrier. A full barrier can pair with anything.
+For example:
+
+ thread 1 thread 2
+ =============== ===============
+ a = 1;
+ smp_wmb();
+ b = 2; x = b;
+ smp_rmb();
+ y = a;
+
+Note that the "writing" thread are accessing the variables in the
+opposite order as the "reading" thread. This is expected: stores
+before the write barrier will normally match the loads after the
+read barrier, and vice versa. The same is true for more than 2
+access and for data dependency barriers:
+
+ thread 1 thread 2
+ =============== ===============
+ b[2] = 1;
+ smp_wmb();
+ x->i = 2;
+ smp_wmb();
+ a = x; x = a;
+ smp_read_barrier_depends();
+ y = x->i;
+ smp_read_barrier_depends();
+ z = b[y];
+
+smp_wmb() also pairs with atomic_mb_read(), and smp_rmb() also pairs
+with atomic_mb_set().
+
+
+COMPARISON WITH LINUX KERNEL MEMORY BARRIERS
+============================================
+
+Here is a list of differences between Linux kernel atomic operations
+and memory barriers, and the equivalents in QEMU:
+
+- atomic operations in Linux are always on a 32-bit int type and
+ use a boxed atomic_t type; atomic operations in QEMU are polymorphic
+ and use normal C types.
+
+- atomic_read and atomic_set in Linux give no guarantee at all;
+ atomic_read and atomic_set in QEMU include a compiler barrier
+ (similar to the ACCESS_ONCE macro in Linux).
+
+- most atomic read-modify-write operations in Linux return void;
+ in QEMU, all of them return the old value of the variable.
+
+- different atomic read-modify-write operations in Linux imply
+ a different set of memory barriers; in QEMU, all of them enforce
+ sequential consistency, which means they imply full memory barriers
+ before and after the operation.
+
+- Linux does not have an equivalent of atomic_mb_read() and
+ atomic_mb_set(). In particular, note that set_mb() is a little
+ weaker than atomic_mb_set().

This is a special option to allow the monitor to be multiplexed onto

@item -serial mon:telnet::4444,server,nowait
