2009-09-04monitor: Port handler_0 to use QDictLuiz Capitulino
This commit ports command handlers that receive no arguments to use the new monitor's dictionary. It might seem no sense to do this, as the handlers have no arguments, but at the end of this porting work all handlers will have the same structure.

2009-09-04monitor: Setup a QDict with arguments to handlersLuiz Capitulino
With this commit monitor_handle_command() will be able to setup a QDict with arguments to command handlers. However, the current 'args[]' method is still being used, next changes will port commands to get their arguments from the dictionary. Two changes are worth noting: 1. The '/' argument type always adds the following standard keys in the dictionary: 'count', 'format' and 'size'. This way, the argument name used in the 'args_type' string doesn't matter 2. The optional argument type '?' doesn't need to pass the additional 'has_arg' argument, hanlders can do the same check with qdict_haskey() Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-09-04monitor: New format for handlers argument typesLuiz Capitulino
Current handlers argument types, as defined in qemu-monitor.hx file, are a sequence of chars where each one represents one argument type of the command handler. The number of chars is also used to know how many arguments a given handler accepts. This commit defines a new format, which makes mandatory the use of a name for each argument. For example, do_eject() command handler is currently defined as: { "eject", "-fB", do_eject, ... } With the new format it becomes: { "eject", "force:-f,filename:B", do_eject, ... } This way the Monitor will be capable of setting up a dictionary, using each argument's name as the key and the argument itself as the value. This commit also adds two new functions: key_get_info() and next_arg_type(), both are used to parse the new format. Currently key_get_info() consumes the 'key' part of the new format and discards it, this way the current parsing code is not affected by this change.

2009-09-04Add wrappers to functions used by the MonitorLuiz Capitulino
Some functions exported to be used by the Monitor as command handlers are also called in other places as regular functions. When those functions got ported to use the Monitor dictionary to pass argments, the callers will have to setup a dictionary to be able to call them. To avoid this problem, this commit add wrappers to those functions, so that we change the wrapper to accept the dictionary, letting the current functions as is. The following wrappers are being added: - do_help_cmd() - do_pci_device_hot_remove() Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-08-27add qemu_error() + friendsGerd Hoffmann
This patch adds some functions for error reporting to address the problem that error messages should be routed to different destinations depending on the context of the caller, i.e. monitor command errors should go to the monitor, command line errors to stderr. qemu_error() is a printf-like function to report errors. qemu_errors_to_file() and qemu_errors_to_mon() switch the destination for the error message to the specified file or monitor. When setting a new destination the old one will be kept. One can switch back using qemu_errors_to_previous(). i.e. it works like a stack. main() calls qemu_errors_to_file(stderr), so errors go to stderr by default. monitor callbacks are wrapped into qemu_errors_to_mon() + qemu_errors_to_previous(), so any errors triggered by monitor commands will go to the monitor. Each thread has its own error message destination. qemu-kvm probably should add a qemu_errors_to_file(stderr) call to the i/o-thread initialization code.

2009-08-27kvm: Simplify cpu_synchronize_state()Avi Kivity
cpu_synchronize_state() is a little unreadable since the 'modified' argument isn't self-explanatory.

2009-08-24Unbreak large mem support by removing kqemuAnthony Liguori
kqemu introduces a number of restrictions on the i386 target. The worst is that it prevents large memory from working in the default build. Furthermore, kqemu is fundamentally flawed in a number of ways. It relies on the TSC as a time source which will not be reliable on a multiple processor system in userspace. Since most modern processors are multicore, this severely limits the utility of kqemu. kvm is a viable alternative for people looking to accelerate qemu and has the benefit of being supported by the upstream Linux kernel. If someone can implement work arounds to remove the restrictions introduced by kqemu, I'm happy to avoid and/or revert this patch. N.B. kqemu will still function in the 0.11 series but this patch removes it from the 0.12 series. Paul, please Ack or Nack this patch. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-08-10Fix do_commit() behaviorLuiz Capitulino
Commit 751c6a17042b5d011013d6963c0505d671cf708e changed the monitor's 'commit' command to this behavior: 1. Any string you type as argument will cause do_commit() to call bdrv_commit() to all devices 2. If you enter a device name, it will be the only one ignored by do_commit() :) The fix is to call bdrv_commit() to the specified device only and ignore the others (when 'all' is not specified).

2009-04-21net: Add support for capturing VLANs (Jan Kiszka)aliguori
This patch is derived from Tristan Gingold's patch. It adds a new VLAN client type that writes all traffic on the VLAN it is attached to into a pcap file. Such a file can then be analyzed offline with Wireshark or tcpdump. Besides rebasing and some minor cleanups, the major differences to the original version are: - support for enabling/disabling via the monitor (host_net_add/remove) - no special ordering of VLAN client list, qemu_send_packet now takes care of properly ordered packets - 64k default capturing limit (I hate tcpdump's default) Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@7200 c046a42c-6fe2-441c-8c8c-71466251a162
