      main: force enabling of I/O thread · 12d4536f
      Anthony Liguori authored
      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
      Paolo Bonzini authored
      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
      Paolo Bonzini authored
      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
      Paolo Bonzini authored
      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
      Blue Swirl authored
      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.
