2012-03-15qapi: Convert migrateLuiz Capitulino
The migrate command is one of those commands where HMP and QMP completely mix up together. This made the conversion to the QAPI (which separates the command into QMP and HMP parts) a bit difficult. The first important change to be noticed is that this commit completes the removal of the Monitor object from migration code, started by the previous commit. Another important and tricky change is about supporting the non-detached mode. That is, if the user doesn't pass '-d' the migrate command will lock the monitor and will only release it when migration is finished. To support this in the new HMP command (hmp_migrate()), it is necessary to create a timer which runs every second and checks if the migration is still active. If it is, the timer callback will re-schedule itself to run one second in the future. If the migration has already finished, the monitor lock is released and the user can use it normally. All these changes should be transparent to the user. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2012-03-15Purge migration of (almost) everything to do with monitorsLuiz Capitulino
The Monitor object is passed back and forth within the migration/savevm code so that it can print errors and progress to the user. However, that approach assumes a HMP monitor, being completely invalid in QMP. This commit drops almost every single usage of the Monitor object, all monitor_printf() calls have been converted into DPRINTF() ones. There are a few remaining Monitor objects, those are going to be dropped by the next commit.

2012-03-14target-lm32/microblaze: Drop second CPU{LM32, MB}State typedefAndreas Färber
Commit 9b9a970a23625de4ae6b7461906a9a0d98d3ca95 (target-lm32/microblaze: Typedef struct CPU{MB,LM32}State) introduced necessary typedefs for cpu_mmu_index() and mmu.h respectively. On some GCC versions this leads to "error: redefinition of typedef". Drop the original typedef to hopefully fix the build.

2012-03-14vnc: don't mess up with iohandlers in the vnc threadCorentin Chary
The threaded VNC servers messed up with QEMU fd handlers without any kind of locking, and that can cause some nasty race conditions. Using qemu_mutex_lock_iothread() won't work because vnc_dpy_cpy(), which will wait for the current job queue to finish, can be called with the iothread lock held. Instead, we now store the data in a temporary buffer, and use a bottom half to notify the main thread that new data is available. vnc_[un]lock_ouput() is still needed to access VncState members like abort, csock or jobs_buffer.

2012-03-14qom: Introduce CPU classAndreas Färber
Reintroduce CPUState as QOM object: It's abstract and derived directly from TYPE_OBJECT for compatibility with the user emulators. The identifier CPUState avoids conflicts between CPU() and the struct. Introduce $(qom-twice-y) to build it separately for system and for user emulators. Prepare a virtual reset method, (re)introduce cpu_reset() as wrapper. Signed-off-by: Andreas Färber <afaerber@suse.de> Reviewed-by: Anthony Liguori <aliguori@us.ibm.com>
