      cutils: work around platform differences in strto{l,ul,ll,ull}

      Linux returns 0 if no conversion was made, while OS X and presumably
      the BSDs return EINVAL.  The OS X convention rejects more invalid
      inputs, so convert to it and adjust the test case.

      Windows returns 1 from strtoul and strtoull (instead of -1) for
      negative out-of-range input; fix it up.

      cpu-exec: fix lock hierarchy for user-mode emulation

      tb_lock has to be taken inside the mmap_lock (example:
      tb_invalidate_phys_range is called by target_mmap), but
      tb_link_page is taking the mmap_lock and it is called
      with the tb_lock held.

      To fix this, take the mmap_lock in tb_find_slow, not
      in tb_link_page.

      There is some iffy lock hierarchy going on in translate-all.c.  To

      functions globally available.

      tcg: add memory barriers in page_find_alloc accesses

      page_find is reading the radix tree outside all locks, so it has to
      use the RCU primitives.  It does not need RCU critical sections
      because the PageDescs are never removed, so there is never a need
      to wait for the end of code sections that use a PageDesc.

      replace spinlock by QemuMutex.

      spinlock is only used in two cases:
        * cpu-exec.c: to protect TranslationBlock
        * mem_helper.c: for lock helper in target-i386 (which seems broken).

      It's a pthread_mutex_t in user-mode, so we can use QemuMutex directly,
      with an #ifdef.  The #ifdef will be removed when multithreaded TCG
      will need the mutex as well.

      cpus: remove tcg_halt_cond and tcg_cpu_thread globals

      This hides the tcg_halt_cond and tcg_cpu_thread global variables
      inside qemu_tcg_init_vcpu.  Multi-threaded TCG will need one
      QemuCond and one QemuThread per virtual cpu, so it's preferrable
      to use cpu->halt_cond and cpu->thread.

      configure: Add support for jemalloc

      This adds "--enable-jemalloc" and "--disable-jemalloc" to allow linking
      to jemalloc memory allocator.

      We have already tcmalloc support,
      but it seem to not working well with a lot of iothreads/disks.

      The main problem is that tcmalloc use a shared thread cache of 16MB
      by default.
      With more threads, this cache is shared, and some bad garbage collections
      can occur if the cache is too low.

      It's possible to tcmalloc cache increase it with a env var:
      TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES=256MB

      With default 16MB, performances are  really bad with more than 2 disks.
      Increasing to 256MB, it's helping but still have problem with 16 
disks/iothreads.

      Jemalloc don't have performance problem with default configuration.

      Here the benchmark results in iops of 1 qemu vm randread 4K iodepth=32,
      with rbd block backend (librbd is doing a lot of memory allocation),
      1 iothread by disk

      rcu: init rcu_registry_lock after fork

      We were unlocking this lock after fork, which is wrong since
      only the thread that holds a mutex is allowed to unlock it.

      Makefile.target: include top level build dir in vpath

      Using ccache with CCACHE_BASEDIR set to $(SRC_PATH) or a parent will
      rewrite all absolute paths to relative paths. This interacts poorly with
      QEMU's two-level build directory scheme. For example, lets say
      BUILD_DIR=$(SRC_PATH)/build so build/blockdev.d will contain:

        blockdev.o: ../blockdev.c ../include/sysemu/block-backend.h \

      Now the target build under build/x86_64-softmmu or similar will depend
      on ../blockdev.o which in turn will get make to source ../blockdev.d to
      check its dependencies. Since make always considers paths relative to
      the current working directory rather than the makefile the path appeared
      in the relative path to ../blockdev.c is useless.

      This change simply adds the top level build directory to vpath so paths
      relative to the source directory, top build directory, and target build
      directory all work just fine.

      tcg: signal-free qemu_cpu_kick

      Signals are slow and do not exist on Win32.  The previous patches
      have done most of the legwork to introduce memory barriers (some
      of them were even there already for the sake of Windows!) and
      we can now set the flags directly in the iothread.

      qemu_cpu_kick_thread is not used anymore on TCG, since the TCG thread is
      never outside usermode while the CPU is running (not halted).  Instead run
      the content of the signal handler (now in qemu_cpu_kick_no_halt) directly.
      qemu_cpu_kick_no_halt is also used in qemu_mutex_lock_iothread to avoid
      the overhead of qemu_cond_broadcast.

      use qemu_cpu_kick instead of cpu_exit or qemu_cpu_kick_thread

      Use the same API to trigger interruption of a CPU, no matter if
      under TCG or KVM.  There is no difference: these calls come from
      the CPU thread, so the qemu_cpu_kick calls will send a signal
      to the running thread and it will be processed synchronously,
      just like a call to cpu_exit.  The only difference is in the
      overhead, but neither call to cpu_exit (now qemu_cpu_kick)
      is in a hot path.

      This is unused.  cpu_exit now is almost exclusively an internal function

      i8257: rewrite DMA_schedule to avoid hooking into the CPU loop

      The i8257 DMA controller uses an idle bottom half, which by default
      does not cause the main loop to exit.  Therefore, the DMA_schedule
      function is there to ensure that the CPU relinquishes the iothread
      mutex to the iothread.

      However, this is not enough since the iothread will call
      aio_compute_timeout() and go to sleep again.  In the iothread
      world, forcing execution of the idle bottom half is much simpler,
      and only requires a call to qemu_notify_event().  Do it, removing
      the need for the "cpu_request_exit" pseudo-irq.  The next patch
      will remove it.

      cpus.c: qemu_mutex_lock_iothread fix race condition at cpu thread init

      When QEMU starts the RCU thread executes qemu_mutex_lock_thread
      causing error "qemu:qemu_cpu_kick_thread: No such process" and exits.

      This isn't occur frequently but in glibc the thread id can exist and
      this not guarantee that the thread is on active/running state. If is
      inserted a sleep(1) after newthread assignment [1] the issue appears.

      So not make assumption that thread exist if first_cpu->thread is set
      then change the validation of cpu to created that is set into cpu
      threads (kvm, tcg, dummy).

      cutils: work around platform differences in strto{l,ul,ll,ull}

      Linux returns 0 if no conversion was made, while OS X and presumably
      the BSDs return EINVAL.  The OS X convention rejects more invalid
      inputs, so convert to it and adjust the test case.

      Windows returns 1 from strtoul and strtoull (instead of -1) for
      negative out-of-range input; fix it up.

      cpu-exec: fix lock hierarchy for user-mode emulation

      tb_lock has to be taken inside the mmap_lock (example:
      tb_invalidate_phys_range is called by target_mmap), but
      tb_link_page is taking the mmap_lock and it is called
      with the tb_lock held.

      To fix this, take the mmap_lock in tb_find_slow, not
      in tb_link_page.

      There is some iffy lock hierarchy going on in translate-all.c.  To

      tcg: add memory barriers in page_find_alloc accesses

      page_find is reading the radix tree outside all locks, so it has to
      use the RCU primitives.  It does not need RCU critical sections
      because the PageDescs are never removed, so there is never a need
      to wait for the end of code sections that use a PageDesc.

      replace spinlock by QemuMutex.

      spinlock is only used in two cases:
        * cpu-exec.c: to protect TranslationBlock
        * mem_helper.c: for lock helper in target-i386 (which seems broken).

      It's a pthread_mutex_t in user-mode, so we can use QemuMutex directly,
      with an #ifdef.  The #ifdef will be removed when multithreaded TCG
      will need the mutex as well.

      cpus: remove tcg_halt_cond and tcg_cpu_thread globals

      This hides the tcg_halt_cond and tcg_cpu_thread global variables
      inside qemu_tcg_init_vcpu.  Multi-threaded TCG will need one
      QemuCond and one QemuThread per virtual cpu, so it's preferrable
      to use cpu->halt_cond and cpu->thread.

      configure: Add support for jemalloc

      This adds "--enable-jemalloc" and "--disable-jemalloc" to allow linking
      to jemalloc memory allocator.

      We have already tcmalloc support,
      but it seem to not working well with a lot of iothreads/disks.

      The main problem is that tcmalloc use a shared thread cache of 16MB
      by default.
      With more threads, this cache is shared, and some bad garbage collections
      can occur if the cache is too low.

      It's possible to tcmalloc cache increase it with a env var:
      TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES=256MB

      With default 16MB, performances are  really bad with more than 2 disks.
      Increasing to 256MB, it's helping but still have problem with 16 
disks/iothreads.

      Jemalloc don't have performance problem with default configuration.

      Here the benchmark results in iops of 1 qemu vm randread 4K iodepth=32,
      with rbd block backend (librbd is doing a lot of memory allocation),
      1 iothread by disk

      Makefile.target: include top level build dir in vpath

      Using ccache with CCACHE_BASEDIR set to $(SRC_PATH) or a parent will
      rewrite all absolute paths to relative paths. This interacts poorly with
      QEMU's two-level build directory scheme. For example, lets say
      BUILD_DIR=$(SRC_PATH)/build so build/blockdev.d will contain:

        blockdev.o: ../blockdev.c ../include/sysemu/block-backend.h \

      Now the target build under build/x86_64-softmmu or similar will depend
      on ../blockdev.o which in turn will get make to source ../blockdev.d to
      check its dependencies. Since make always considers paths relative to
      the current working directory rather than the makefile the path appeared
      in the relative path to ../blockdev.c is useless.

      This change simply adds the top level build directory to vpath so paths
      relative to the source directory, top build directory, and target build
      directory all work just fine.

      tcg: signal-free qemu_cpu_kick

      Signals are slow and do not exist on Win32.  The previous patches
      have done most of the legwork to introduce memory barriers (some
      of them were even there already for the sake of Windows!) and
      we can now set the flags directly in the iothread.

      qemu_cpu_kick_thread is not used anymore on TCG, since the TCG thread is
      never outside usermode while the CPU is running (not halted).  Instead run
      the content of the signal handler (now in qemu_cpu_kick_no_halt) directly.
      qemu_cpu_kick_no_halt is also used in qemu_mutex_lock_iothread to avoid
      the overhead of qemu_cond_broadcast.

      use qemu_cpu_kick instead of cpu_exit or qemu_cpu_kick_thread

      Use the same API to trigger interruption of a CPU, no matter if
      under TCG or KVM.  There is no difference: these calls come from
      the CPU thread, so the qemu_cpu_kick calls will send a signal
      to the running thread and it will be processed synchronously,
      just like a call to cpu_exit.  The only difference is in the
      overhead, but neither call to cpu_exit (now qemu_cpu_kick)
      is in a hot path.

      i8257: rewrite DMA_schedule to avoid hooking into the CPU loop

      The i8257 DMA controller uses an idle bottom half, which by default
      does not cause the main loop to exit.  Therefore, the DMA_schedule
      function is there to ensure that the CPU relinquishes the iothread
      mutex to the iothread.

      However, this is not enough since the iothread will call
      aio_compute_timeout() and go to sleep again.  In the iothread
      world, forcing execution of the idle bottom half is much simpler,
      and only requires a call to qemu_notify_event().  Do it, removing
      the need for the "cpu_request_exit" pseudo-irq.  The next patch
      will remove it.

      cpus.c: qemu_mutex_lock_iothread fix race condition at cpu thread init

      When QEMU starts the RCU thread executes qemu_mutex_lock_thread
      causing error "qemu:qemu_cpu_kick_thread: No such process" and exits.

      This isn't occur frequently but in glibc the thread id can exist and
      this not guarantee that the thread is on active/running state. If is
      inserted a sleep(1) after newthread assignment [1] the issue appears.

      So not make assumption that thread exist if first_cpu->thread is set
      then change the validation of cpu to created that is set into cpu
      threads (kvm, tcg, dummy).
