2009-10-27Add chardev option to disable signal.Kusanagi Kouichi
If I am using vga and serial which is stdio and hit C-c on serial console, qemu terminates. That is annoying for me. So make it configurable whether signal is generated when C-c is hit. Signed-off-by: Kusanagi Kouichi <slash@ac.auone-net.jp> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-09-12Fix sys-queue.h conflict for goodBlue Swirl
Problem: Our file sys-queue.h is a copy of the BSD file, but there are some additions and it's not entirely compatible. Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896, f40d753718c72693c5f520f0d9899f6e50395e94, 96555a96d724016e13190b28cffa3bc929ac60dc and 3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file. Revert the previous hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-09-11monitor: fix muxingGerd Hoffmann
make the mux driver send mux_in and mux_out events when switching focus while hooking up more handlers. stop using CharDriverState->focus in monitor.c, track state using the mux events instead. This also removes the implicit assumtion that a muxed monitor allways has mux channel 0. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-09-11Allow -serial chardev:<name>Gerd Hoffmann
Lets put -chardev into use now. With this patch applied chardev:name is accepted as chardev specification everywhere, i.e. now you can: -chardev stdio,id=ttyS0 -serial chardev:ttyS0 which does the same as '-serial stdio". Muxing can be done this way: -chardev stdio,id=mux,mux=on -serial chardev:mux -monitor chardev:mux You can mux more than two streams.

2009-09-11switch chardev to QemuOpts: infrastructure, null deviceGerd Hoffmann
start switching chardevs to QemuOpts. This patch adds the infrastructure and converts the null device. The patch brings two new functions: qemu_chr_open_opts() same as qemu_chr_open(), but uses QemuOpts instead of a option char string. qemu_chr_parse_compat() accepts a traditional chardev option string, returns the corresponding QemuOpts instance, to handle backward compatibility. The patch also adds a new -chardev switch which can be used to create named+unconnected chardevs, like this: -chardev null,id=test This uses the new qemu_chr_open_opts. Thus with this patch alone only the null device works. The other devices will follow ... Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

This patch fixes several issues around closing char devices. Affected were pty (timer was left behind, even running), udp (no close handling at all) and tcp (missing async IO handler cleanup).

2009-03-05monitor: Improve mux'ed console experience (Jan Kiszka)aliguori
Up to now, you never really knew if you already switched the console after pressing CTRL-A C or if you mistyped it again. This patch clarifies the situation by providing a prompt in a new line and injecting a linebreak when switching away again. For this purpose, the two events CHR_EVENT_MUX_IN and CHR_EVENT_MUX_OUT are introduced and distributed on focus switches.

2009-03-05monitor: Decouple terminals (Jan Kiszka)aliguori
Currently all registered (and activate) monitor terminals work in broadcast mode: Everyone sees what someone else types on some other terminal and what the monitor reports back. This model is broken when you have a management monitor terminal that is automatically operated and some other terminal used for independent guest inspection. Such additional terminals can be multiplexed device channels or a gdb frontend connected to QEMU's stub. Therefore, this patch decouples the buffers and states of all monitor terminals, allowing the user to operate them independently. It finally starts to use the 'mon' parameter that was introduced earlier with the API rework. It also defines the default monitor: the first instantance that has the MONITOR_IS_DEFAULT flag set, and that is the monitor created via the "-monitor" command line switch (or "vc" if none is given). As the patch requires to rework the monitor suspension interface, it also takes the freedom to make it "truely" suspending (so far suspending meant suppressing the prompt, but inputs were still processed).

2009-03-05monitor: Rework API (Jan Kiszka)aliguori
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.

2009-03-05char-mux: Use separate input buffers (Jan Kiszka)aliguori
Currently, the intermediate input buffer of mux'ed character devices records data across all sub-devices. This has the side effect that we easily leak data recorded over one sub-devices to another once we switch the focus. Avoid data loss and confusion by defining exclusive buffers. Note: In contrast to the original author's claim, the buffering concept still breaks down when the fifo of the currently active sub-device is full. As we cannot accept futher data from this point on without risking to loose it, we will also miss escape sequences, just like without all that buffering. In short: There is no reliable escape sequence handling without infinite buffers or the risk of loosing some data.

2009-03-05char: Fix initial reset (Jan Kiszka)aliguori
Recent changes to the graphical console initialization broke the initial CHR_EVENT_RESET distribution. The reset BHs generated on char device initialization are now already consumed during machine init (ide init ... -> qemu_aio_wait -> qemu_bh_poll). Therefore, this patch moves the initial qemu_chr_reset calls into a separate funtion which is called after machine init.

2009-01-16Fix character devices after DisplayState refactoringaliguori
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.
