With this commit QMP will be started in Capabilities Negotiation mode, where the only command allowed to run is 'qmp_capabilities'. All other commands will return CommandNotFound error. Asynchronous messages are not delivered either. When 'qmp_capabilities' is successfully executed QMP enters in Command mode, where all commands (except 'qmp_capabilities') are allowed to run and asynchronous messages are delivered.

This command will be used to enable QMP capabilities advertised by the capabilities array. Note that it will be mandatory to issue this command in order to make QMP functional (although this behavior is not being enforced by this commit). Also, as we don't have any capabilities yet, the new command doesn't accept any arguments. I will postpone the decision for a format for this until we get our first capability. Finally, this command is visible from the user Monitor too, in the meaning that you can execute it but it won't do anything. Making it only visible in QMP is beyond this series' goal, as it requires changes in unrelated places.

With capability negotiation support clients will only have a chance to check QEMU's version (ie. issue 'query-version') after the negotiation procedure is done. It might be useful to clients to check QEMU's version before negotiating features, though. To allow that, this commit adds the QEMU's version object to the greeting message. Not really sure this is needed, but doesn't hurt anyway. Signed-off-by: NLuiz Capitulino <lcapitulino@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

This fixes a segfault due to buffer overrun in the usb-serial device. The memcpy was incrementing the start location by recv_used yet, the computation of first_size (how much to write at the end of the buffer before wrapping to the front) was not accounting for it. This causes the next element after the receive buffer (recv_ptr) to get overwritten with random data.

I have streaming audio devices working within qemu-kvm. This is a port of the changes to qemu. Streaming audio generates a series of isochronous requests that are repetitive and time sensitive. The URBs need to be submitted in consecutive USB frames and responses need to be handled in a timely manner. Summary of the changes for isochronous requests: 1. The initial 'valid' value is increased to 32. It needs to be higher than its current value of 10 since the host adds a 10 frame delay to the scheduling of the first request; if valid is set to 10 the first isochronous request times out and qemu cancels it. 32 was chosen as a nice round number, and it is used in the path where a TD-async pairing already exists. 2. The token field in the TD is *not* unique for isochronous requests, so it is not a good choice for finding a matching async request. The buffer (where to write the guest data) is unique, so use that value instead. 3. TD's for isochronous request need to be completed in the async completion handler so that data is pushed to the guest as soon as it is available. The uhci code currently attempts to process complete isochronous TDs the next time the UHCI frame with the request is processed. The results in lost data since the async requests will have long since timed out based on the valid parameter. Increasing the valid value is not acceptable as it introduces a 1+ second delay in the data getting pushed to the guest. 4. The frame timer needs to be run on 1 msec intervals. Currently, the expire time for the processing the next frame is computed after the processing of each frame. This regularly causes the scheduling of frames to shift in time. When this happens the periodic scheduling of the requests is broken and the subsequent request is seen as a new request by the host resulting in a 10 msec delay (first isochronous request is scheduled for 10 frames from when the URB is submitted). [ For what's worth a small change is needed to the guest driver to have more outstanding URBs (at least 4 URBs with 5 packets per URB).] Signed-off-by: NDavid Ahern <daahern@cisco.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

At least for Linux distributions UTF-8 is now standard, so the QEMU documentation should use this encoding, too. Even if there was currently only a single special character using ISO-8859-1, this might change in the future. So the texinfo keywords @documentlanguage and @documentencoding now document the language and the encoding. The special character was changed to UTF-8 (it could also have been changed to an x, but the original cross looks really nice if it is displayed correctly). These changes fix the html presentation at http://www.qemu.org/qemu-doc.html#SEC65 (ARM System emulator).

Clean up the current mess about figuring out which flags to pass to the driver. BDRV_O_FILE, BDRV_O_SNAPSHOT and BDRV_O_NO_BACKING are flags only used by the block layer internally so filter them out directly.

This commit introduces the bdrv_mon_event() function, which should be called by block subsystems (eg. IDE) when a I/O error occurs, so that an QMP event is emitted. The following information is currently provided in the event: - device name - operation (ie. "read" or "write") - action taken (eg. "stop") Event example: { "event": "BLOCK_IO_ERROR", "data": { "device": "ide0-hd1", "operation": "write", "action": "stop" }, "timestamp": { "seconds": 1265044230, "microseconds": 450486 } } Signed-off-by: NLuiz Capitulino <lcapitulino@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

Makefile already supported dvi, html and info formats, but pdf was missing. pdf is especially convenient for printing and for documentation reviews. I hope it will help to improve qemu's documentation. Make now supports the new target 'pdf' which will create qemu-doc.pdf and qemu-tech.pdf. It is also possible to build both files individually. texi2pdf and texi2dvi are rather noisy, so normally some less important warnings are suppressed. When make is called with V=1 (verbose mode), warnings are not suppressed. The patch also sorts the documentation targets alphabetically and wraps a line which was too long.
