* Add wrappers to functions used by the MonitorLuiz Capitulino2009-09-041-0/+1
| | | | | | | | | | | | | | | | | | | | | 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>

* add qemu_error() + friendsGerd Hoffmann2009-08-271-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Unbreak large mem support by removing kqemuAnthony Liguori2009-08-241-4/+0
| | | | | | | | | | | | | | | | | | | | | | 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>
* QEMU set irq0override in fw_cfgJes Sorensen2009-08-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Hi, After discussing the issue with Avi, Gleb and a couple others on irq, we came to the conclusion that it is preferred to have QEMU request features from the BIOS, rather than notifying the BIOS that it is running on QEMU or KVM. This way memory ranges can change etc. and an older BIOS will continue to work on newer QEMU if it receives the info as a fw_cfg value. This one also matches what qemu-kvm does for irq0override, except I haven't made it configurable. I leave that as an exercise for whoever would be interested in switching off irq0override. Thanks, Jes Set irq0 override in fw_cfg, informing the BIOS that QEMU expects override on irq0. This matches qemu-kvm, and will help sharing a single BIOS binary.

* monitor: Rework API (Jan Kiszka)aliguori2009-03-051-11/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
