* qemu-tool: Fix mixup of int64 and int64_tAndreas Färber2012-01-191-2/+2
| | | | | | | | | | | Commit cbcfa0418f0c196afa765f5c9837b9344d1adcf3 (link the main loop and its dependencies into the tools) introduced stray usages of int64. Use int64_t instead.

* prepare for future GPLv2+ relicensingPaolo Bonzini2012-01-131-0/+2
| | | | | | | | | All files under GPLv2 will get GPLv2+ changes starting tomorrow. event_notifier.c and exec-obsolete.h were only ever touched by Red Hat employees and can be relicensed now. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
* link the main loop and its dependencies into the toolsPaolo Bonzini2011-12-221-19/+23
| | | | | | | | Using the main loop code from QEMU enables tools to operate fully asynchronously. Advantages include better Windows portability (for some definition of portability) over glib's. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

* qemu-tool: Stub out qemu-timer functionsStefan Hajnoczi2011-05-181-0/+25
| | | | | | | | | | | | | | | | | | Block drivers may use timers for flushing metadata to disk or reconnecting to a network drive. Stub out the following functions in qemu-tool.c: QEMUTimer *qemu_new_timer_ns(QEMUClock *clock, int scale, QEMUTimerCB *cb, void *opaque) void qemu_free_timer(QEMUTimer *ts) void qemu_del_timer(QEMUTimer *ts) void qemu_mod_timer(QEMUTimer *ts, int64_t expire_time) int64_t qemu_get_clock_ns(QEMUClock *clock) They will result in timers never firing when linked against qemu-tool.o.

* tools: Use real async.c instead of stubsKevin Wolf2011-03-151-43/+4
| | | | | | | | | | | | It's wrong to call BHs directly, even in tools. The only operations that schedule BHs are called in a loop that (indirectly) contains a call to qemu_bh_poll anyway, so we're not losing the scheduled BHs: Tools either use synchronous functions, which are guaranteed to have completed (including any BHs) when they return; or if they use asynchronous functions, they need to call qemu_aio_wait() or similar functions already today.

* qemu-timer: move commonly used timer code to qemu-timer-commonBlue Swirl2010-10-231-7/+0
| | | | | | | | | | | | | | | | | | | | 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.

* error: Link qemu-img, qemu-nbd, qemu-io with qemu-error.oMarkus Armbruster2010-03-271-34/+15
| | | | | | | | | | | | | The location tracking interface is used by code shared with qemi-img, qemu-nbd and qemu-io, so it needs to be available there. Commit 827b0813 provides it in a rather hamfisted way: it adds a dummy implementation to qemu-tool.c. It's cleaner to provide the real thing, and put a few more dummy monitor functions into qemu-tool.c.

* error: Infrastructure to track locations for error reportingMarkus Armbruster2010-03-161-0/+24
| | | | | | | | | | | | | | | | | | New struct Location holds a location. So far, the only location is LOC_NONE, so this doesn't do anything useful yet. Passing the current location all over the place would be too cumbersome. Hide it away in static cur_loc instead, and provide accessors. Print it in error_report(). Store it in QError, and print it in qerror_print(). Store it in QemuOpt, for use by qemu_opts_foreach(). This makes error_report() do the right thing when it runs within qemu_opts_foreach(). We may still have to store it in other data structures holding user input for better error messages. Left for another day.
* error: Replace qemu_error() by error_report()Markus Armbruster2010-03-161-1/+1
| | | | | | | | | | | | | error_report() terminates the message with a newline. Strip it it from its arguments. This fixes a few error messages lacking a newline: net_handle_fd_param()'s "No file descriptor named %s found", and tap_open()'s "vnet_hdr=1 requested, but no kernel support for IFF_VNET_HDR available" (all three versions). There's one place that passes arguments without newlines intentionally: load_vmstate(). Fix it up.

* QMP: Asynchronous events infrastructureLuiz Capitulino2009-12-031-0/+4
| | | | | | | | | | | | | | | | | | Asynchronous events are generated with a call to monitor_protocol_event(). This function builds the right data-type and emit the event right away. The emitted data is always a JSON object and its format is as follows: { "event": json-string, "timestamp": { "seconds": json-number, "microseconds": json-number }, "data": json-value } This design is based on ideas by Amit Shah <amit.shah@redhat.com>.

* monitor: Rework API (Jan Kiszka)aliguori2009-03-051-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor the monitor API and prepare it for decoupled terminals: term_print functions are renamed to monitor_* and all monitor services gain a new parameter (mon) that will once refer to the monitor instance the output is supposed to appear on. However, the argument remains unused for now. All monitor command callbacks are also extended by a mon parameter so that command handlers are able to pass an appropriate reference to monitor output services. For the case that monitor outputs so far happen without clearly identifiable context, the global variable cur_mon is introduced that shall once provide a pointer either to the current active monitor (while processing commands) or to the default one. On the mid or long term, those use case will be obsoleted so that this variable can be removed again. Due to the broad usage of the monitor interface, this patch mostly deals with converting users of the monitor API. A few of them are already extended to pass 'mon' from the command handler further down to internal functions that invoke monitor_printf. At this chance, monitor-related prototypes are moved from console.h to a new monitor.h. The same is done for the readline API.

* Fix IO performance regression in sparcaliguori2008-10-081-0/+4
| | | | | | | | | | | | | | | | | | Replace signalfd with signal handler/pipe. There is no way to interrupt the CPU execution loop when a file descriptor becomes readable. This results in a large performance regression in sparc emulation during bootup. This patch switches us to signal handler/pipe which was originally suggested by Ian Jackson. The signal handler lets us interrupt the CPU emulation loop while the write to a pipe lets us avoid the select/signal race condition.

* Use common objects for qemu-img and qemu-nbdaliguori2008-09-151-0/+83
Right now, we sprinkle #if defined(QEMU_IMG) && defined(QEMU_NBD) all over the code. It's ugly and causes us to have to build multiple object files for linking against qemu and the tools. This patch introduces a new file, qemu-tool.c which contains enough for qemu-img, qemu-nbd, and QEMU to all share the same objects. This also required getting qemu-nbd to be a bit more Windows friendly. I also changed the Windows block-raw to use normal IO instead of overlapping IO since we don't actually do AIO yet on Windows. I changed the various #if 0's to #if WIN32_AIO to make it easier for someone to eventually fix AIO on Windows. After this patch, there are no longer any #ifdef's related to qemu-img and qemu-nbd.
