      main: force enabling of I/O thread · 12d4536f
      由 Anthony Liguori 提交于 
      Enabling the I/O thread by default seems like an important part of declaring
1.0.  Besides allowing true SMP support with KVM, the I/O thread means that the
TCG VCPU doesn't have to multiplex itself with the I/O dispatch routines which
currently requires a (racey) signal based alarm system.

I know there have been concerns about performance.  I think so far the ones that
have come up (virtio-net) are most likely due to secondary reasons like
decreased batching.

I think we ought to force enabling I/O thread early in 1.0 development and
commit to resolving any lingering issues.

      remove qemu_get_clock · 6d5ad9bf
      由 Paolo Bonzini 提交于 
      These patches are already not doing a great service to out-of-tree
modifications to QEMU.  However, at least we can warn them by getting
rid of the old confusing functions, or otherwise causing compilation
errors.  This patch removes qemu_get_clock; the previous one changed
qemu_new_timer's signature.

      add a generic scaling mechanism for timers · 4a998740
      由 Paolo Bonzini 提交于 
      This enables rt_clock timers to use nanosecond resolution, just by
using the _ns functions; there is really no reason to forbid that.

Migrated timers are all using vm_clock (of course; but I checked that
anyway) so the timers in the savevm files are already in nanosecond
resolution.  So this patch makes no change to the migration format.

      change all other clock references to use nanosecond resolution accessors · 74475455
      由 Paolo Bonzini 提交于 
      This was done with:

    sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \
        $(git grep -l 'qemu_get_clock\>' )
    sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \
        $(git grep -l 'qemu_new_timer\>' )

after checking that get_clock and new_timer never occur twice
on the same line.  There were no missed occurrences; however, even
if there had been, they would have been caught by the compiler.

There was exactly one false positive in qemu_run_timers:

     -    current_time = qemu_get_clock (clock);
     +    current_time = qemu_get_clock_ns (clock);

which is of course not in this patch.

      qemu-timer: move commonly used timer code to qemu-timer-common · c57c846a
      由 Blue Swirl 提交于 
      Move timer init functions to a new file, qemu-timer-common.c. Make other
critical timer functions inlined to preserve performance in
qemu-timer.c, also move muldiv64() (used by the inline functions)
to qemu-timer.h.

Adjust block/raw-posix.c and simpletrace.c to use get_clock() directly.
Remove a similar/duplicate definition in qemu-tool.c.

Adjust hw/omap_clk.c to include qemu-timer.h because muldiv64() is used
there.

After this change, tracing can be used also for user code and
simpletrace on Win32.
