2010-03-21Revert "Convert atexit users to exit_notifier"Anthony Liguori1-9/+2
This reverts commit d7234f4d7e373a708e1df9ab565a71b71b189025. Conflicts: hw/xen_machine_pv.c This should have never been committed. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-03-19Convert atexit users to exit_notifierAnthony Liguori1-2/+9
All of these users have global state so we really don't see a benefit from exit_notifier. However, using exit_notifier means that there's one less justification for having global state in the first place. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Patch http://permalink.gmane.org/gmane.comp.emulators.qemu/63472 handle close when using tty devices (like /dev/ttyS0), yet tty based monitor are not restoring terminal attributes (as done with stdio based monitor), when closing qemu after that command: $ qemu -monitor /dev/tty the terminal is not responding until you write reset (blindly), this patch fix it Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-02-22add close callback for tty-based char deviceDavid Ahern1-0/+17
v1 -> v2 coding style changes Add a tty close callback. Right now if a guest device that is connected to a tty-based chardev in the host is removed, the tty is not closed. With this patch it is closed. Example use case is connecting an emulated USB serial cable in the guest to ttyS0 of the host using the monitor command: usb_add serial::/dev/ttyS0 and then removing the device with: usb_del serial::/dev/ttyS0 Signed-off-by: David Ahern <daahern@cisco.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-11-17char: rename qemu_chr_reset to qemu_chr_generic_openAmit Shah1-11/+11
This function sends out the OPENED event to backends that have drive the chardevs. The 'reset' is now a historical artifact and we can now just call the function for what it is. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17char: Remove special init_reset handlingAmit Shah1-9/+0
The initial_reset sent to chardevs doesn't do much other than setting a bool to true. Char devices are interested in the open event and that gets sent whenever the device is opened. Moreover, the reset logic breaks as and when qemu's bh scheduling changes. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17char: don't limit data sent to backends to 1k per bufferAmit Shah1-6/+8
chardevs have a 'can_read' function via which backends specify the amount of data they can receive. When can_read returns > 0, apps can start sending data. However, each chardev driver here allows a max. of 1k bytes inspite of the backend being able to receive more. The best we can do here is to allocate s->max_size bytes from the heap on each call (which is the number returned by the backend from the can_read call). This is an intermediate step to bump up the bytes written in each call to 4k. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-10-21char: emit the OPENED event only when a new char connection is openedAmit Shah1-1/+6

2009-09-12Fix sys-queue.h conflict for goodBlue Swirl1-9/+9
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 Hoffmann1-0/+4
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.

2009-09-11Allow -serial chardev:<name>Gerd Hoffmann1-0/+16
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 Hoffmann1-4/+67
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>

First step cleaning up the drives handling. This one does nothing but removing drives_table[], still it became seriously big. drive_get_index() is gone and is replaced by drives_get() which hands out DriveInfo pointers instead of a table index.
