      Fix character devices after DisplayState refactoring · 2796dae0
      由 aliguori 提交于 
      The DisplayState refactoring changed the machine init function to create a
DisplayState for each VGA device instead of being passed an existing
DisplayState.  This change is critical to enable multiple graphics device
support.

Unfortunately, the serial/parallel/console code is structured today to run
before machine init to fill out the CharDriverState table which the machine
init function uses to determine whether to create the required devices.

Since a 'vc' is a type of CharDriverState, the CharDriverState code requires
that a DisplayState exist before it runs creating a circular dependency.

To fix this, this splits the creation of the initial CharDriverState from
the initialization of the text console.  We can then in a second step associate
a DisplayState with all TextConsoles.  This allows us to create the
CharDriverState's first, machine init, then associate the TextConsoles with
a DisplayState.

This code screams for more cleanup.

      graphical_console_init change (Stefano Stabellini) · 3023f332
      由 aliguori 提交于 
      Patch 5/7

This patch changes the graphical_console_init function to return an
allocated DisplayState instead of a QEMUConsole.

This patch contains just the graphical_console_init change and few other
modifications mainly in console.c and vl.c.
It was necessary to move the display frontends (e.g. sdl and vnc)
initialization after machine->init in vl.c.

This patch does *not* include any required changes to any device, these
changes come with the following patches.

Patch 6/7

This patch changes the QEMUMachine init functions not to take a
DisplayState as an argument because is not needed any more;

In few places the graphic hardware initialization function was called
only if DisplayState was not NULL, now they are always called.
Apart from these cases, the rest are all mechanical substitutions.

Patch 7/7

This patch updates the graphic device code to use the new
graphical_console_init function.

As for the previous patch, in few places graphical_console_init was called
only if DisplayState was not NULL, now it is always called.
Apart from these cases, the rest are all mechanical substitutions.

      Revert r5636 to fix icount on hosts w/o high-res clocks · 357c692c
      由 aliguori 提交于 
      Changeset r5636 changed the timers to run in the alarm callback.  The 
alarm callback can only be called as frequently as the host alarm timer 
fires.  For older Linux hosts and possibly non-Linux hosts, this can be 
as high as a 1ms granularity.

icount calculates the select timeout based on the next deadline and 
select is usually capable of sleeping for a short period of time than 
alarm timer granularity.  This means that changing the timer callbacks 
to be based on alarm firing caused timers to fire much later than they 
ought to when using icount.

      gdbstub: manage CPUs as threads (Jan Kiszka) · 880a7578
      由 aliguori 提交于 
      This patch enhances QEMU's built-in debugger for SMP guest debugging.
Using the thread support of the gdb remote protocol, each VCPU is mapped
on a pseudo thread and exposed to the gdb frontend. This way you can
easy switch the focus of gdb between the VCPUs and observe their states.
On breakpoint hit, the focus is automatically adjusted just as for
normal multi-threaded application under gdb control.

Furthermore, the patch propagates breakpoint and watchpoint insertions
or removals to all CPUs, not just the current one as it was the case so
far. Without this, SMP guest debugging was practically unfeasible.
