[Qemu-devel] [PATCH v4 00/12] cpu-exec: Safe work in quiescent state

[Sergey Fedorov]

From: Sergey Fedorov <address@hidden>

Hi,

This is a v4 for the series [1]. There's only a small change to keep
tb_flush() statistic and debugging output sane. I also picked up
"Reviewed-by" tags.

This series is available at a public git repository:

    https://github.com/sergefdrv/qemu.git safe-cpu-work-v4

Summary of changes in v4:
 - keep tb_flush() statistics and debugging output sane
Summary of changes in v3:
 - bsd-user support added
 - 'tb_flushed' removed
Summary of changes in v2:
 - atomic_dec_fetch() used to decrement 'safe_work_pending'
 - more work to use/fix passing CPUState to run_on_cpu helpers
 - instead of wrapping conditional variables access, use QemuMutex and
   QemuCond in linux-user and just wrap getting of the relevant mutex.
 - document new public API
 - Rename 'tcg_pending_cpus' to 'tcg_pending_threads'

Kind regards,
Sergey
