2013-01-17HMP: add sub command table to infoWenchao Xia

2012-10-24block: introduce BLOCK_JOB_READY eventPaolo Bonzini
Even for jobs that need to be manually completed, management may want to take care itself of the completion, not requiring the user to issue a command to terminate the job. In this case we want to avoid that they poll us continuously, waiting for completion to become available.

This patch adds support that will enable adding an fd that was inherited on the command line to an fd set.

Move the DUMP_FPU and DUMP_CCOP flags for cpu_dump_state() from being x86-specific flags to being generic ones. This allows us to drop some TARGET_I386 ifdefs in various places, and means that we can (potentially) be more consistent across architectures about which monitor commands or debug abort printouts include FPU register contents and info about QEMU's condition-code optimisations.

2012-09-28block: introduce block job errorPaolo Bonzini
The following behaviors are possible: 'report': The behavior is the same as in 1.1. An I/O error, respectively during a read or a write, will complete the job immediately with an error code. 'ignore': An I/O error, respectively during a read or a write, will be ignored. For streaming, the job will complete with an error and the backing file will be left in place. For mirroring, the sector will be marked again as dirty and re-examined later. 'stop': The job will be paused and the job iostatus will be set to failed or nospace, while the VM will keep running. This can only be specified if the block device has rerror=stop and werror=stop or enospc. 'enospc': Behaves as 'stop' for ENOSPC errors, 'report' for others. In all cases, even for 'report', the I/O error is reported as a QMP event BLOCK_JOB_ERROR, with the same arguments as BLOCK_IO_ERROR. It is possible that while stopping the VM a BLOCK_IO_ERROR event will be reported and will clobber the event from BLOCK_JOB_ERROR, or vice versa. This is not really avoidable since stopping the VM completes all pending I/O requests. In fact, it is already possible now that a series of BLOCK_IO_ERROR events are reported with rerror=stop, because vm_stop calls bdrv_drain_all and this can generate further errors.

2012-09-05qapi: convert sendkeyAmos Kong
Convert 'sendkey' to use QAPI. QAPI passes key's index of mapping table to qmp_send_key(), not keycode. So we use help functions to convert key/code to index of key_defs, and 'index' will be converted to 'keycode' inside qmp_send_key(). For qmp, QAPI would check invalid key and raise error. For hmp, invalid key is checked in hmp_send_key(). 'send-key' of QMP doesn't support key in hexadecimal format.

Patch also moved key_defs[] to input.c, and removed useless KeyDef struct. Key's index in QKeyCode enmu is same as keycode's index in new key_defs[].

2012-09-05spice migration: add QEVENT_SPICE_MIGRATE_COMPLETEDYonit Halperin
When migrating, libvirt queries the migration status, and upon migration completions, it closes the migration src. On the other hand, when migration is completed, spice transfers data from the src to destination via the client. This data is required for keeping the spice session after migration, without suffering from data loss and inconsistencies. In order to allow this data transfer, we add QEVENT for signaling libvirt that spice migration has completed, and libvirt needs to wait for this event before quitting the src process.

2012-08-23monitor: move json init from OPEN event to initAnthony Liguori
At some point in the past, the OPEN event was changed to be issued from a bottom half. This creates a small window whereas a data callback registered in init may be invoked before the OPEN event has been issued. This is reproducible with: echo "{'execute': 'qmp_capabilities'}" | qemu-system-x86_64 -M none -qmp stdio We can fix this for the monitor by moving the parser initialization to init.

2012-08-15monitor: Clean up fd sets on monitor disconnectCorey Bryant
Fd sets are shared by all monitor connections. Fd sets are considered to be in use while at least one monitor is connected. When the last monitor disconnects, all fds that are members of an fd set with no outstanding dup references are closed.

2012-08-15qapi: Introduce add-fd, remove-fd, query-fdsetsCorey Bryant
This patch adds support that enables passing of file descriptors to the QEMU monitor where they will be stored in specified file descriptor sets. A file descriptor set can be used by a client like libvirt to store file descriptors for the same file. This allows the client to open a file with different access modes (O_RDWR, O_WRONLY, O_RDONLY) and add/remove the passed fds to/from an fd set as needed. This will allow QEMU to (in a later patch in this series) "open" and "reopen" the same file by dup()ing the fd in the fd set that corresponds to the file, where the fd has the matching access mode flag that QEMU requests. The new QMP commands are: add-fd: Add a file descriptor to an fd set remove-fd: Remove a file descriptor from an fd set query-fdsets: Return information describing all fd sets Note: These commands are not compatible with the existing getfd and closefd QMP commands.
