2009-03-05char-mux: Use separate input buffers (Jan Kiszka)aliguori1-10/+14
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)aliguori1-4/+16
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 refactoringaliguori1-2/+2
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.

2009-01-16graphical_console_init change (Stefano Stabellini)aliguori1-2/+2
Patch 5/7 This patch changes the graphical_console_init function to return an allocated DisplayState instead of a QEMUConsole. This patch contains just the graphical_console_init change and few other modifications mainly in console.c and vl.c. It was necessary to move the display frontends (e.g. sdl and vnc) initialization after machine->init in vl.c. This patch does *not* include any required changes to any device, these changes come with the following patches. Patch 6/7 This patch changes the QEMUMachine init functions not to take a DisplayState as an argument because is not needed any more; In few places the graphic hardware initialization function was called only if DisplayState was not NULL, now they are always called. Apart from these cases, the rest are all mechanical substitutions. Patch 7/7 This patch updates the graphic device code to use the new graphical_console_init function. As for the previous patch, in few places graphical_console_init was called only if DisplayState was not NULL, now it is always called. Apart from these cases, the rest are all mechanical substitutions.

2008-11-11sockets: switch over tcp/telnet/unix serial line to new helper functions ↵aliguori1-74/+32
(Gerd Hoffman) This switches the tcp, telnet and unix socket support for character devices (serial/parallel, ...) to the new socket helpers. Thereby they gain IPv6 support and also get ability to search for a free tcp port. Syntax is the same as for vnc, using a to= option, like this: -serial tcp:localhost:5000,to=5099,server This will check the 5000 -> 5099 port range (inclusive) for a free tcp port. Likewise you can get auto-allocated unix sockets by specifying an empty path: -serial unix:,server qemu will create a randomly named socket in $TMPDIR then. tcp also got new "ipv4" and "ipv6" options to make qemu try only the specified internet protocol version. You can use the "info chardev" command added by the first patch in this series to figure the tcp port / unix socket actually allocated.
