2011-08-04balloon: Separate out stat and balloon handlingAmit Shah
Passing on '0' as ballooning target to indicate retrieval of stats is bad API. It also makes 'balloon 0' in the monitor cause a segfault. Have two different functions handle the different functionality instead. Detailed explanation from Markus's review: 1. do_info_balloon() is an info_async() method. It receives a callback with argument, to be called exactly once (callback frees the argument). It passes the callback via qemu_balloon_status() and indirectly through qemu_balloon_event to virtio_balloon_to_target(). virtio_balloon_to_target() executes its balloon stats half. It stores the callback in the device state. If it can't send a stats request, it resets stats and calls the callback right away. Else, it sends a stats request. The device model runs the callback when it receives the answer. Works. 2. do_balloon() is a cmd_async() method. It receives a callback with argument, to be called when the command completes. do_balloon() calls it right before it succeeds. Odd, but should work. Nevertheless, it passes the callback on via qemu_ballon() and indirectly through qemu_balloon_event to virtio_balloon_to_target(). a. If the argument is non-zero, virtio_balloon_to_target() executes its balloon half, which doesn't use the callback in any way. Odd, but works. b. If the argument is zero, virtio_balloon_to_target() executes its balloon stats half, just like in 1. It either calls the callback right away, or arranges for it to be called later. Thus, the callback runs twice: use after free and double free. Test case: start with -S -device virtio-balloon, execute "balloon 0" in human monitor. Runs the callback first from virtio_balloon_to_target(), then again from do_balloon().

2011-08-04virtio-balloon: Separate status handling into separate functionAmit Shah
Separate out the code to retrieve balloon info from the code that sets balloon values. This will be used to separate the two callbacks from balloon.c and help cope with 'balloon 0' on the monitor. Currently, 'balloon 0' causes a segfault in monitor_resume(). Signed-off-by: Amit Shah <amit.shah@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com>

2011-07-30exec.h cleanupBlue Swirl
Move softmmu_exec.h include directives from target-*/exec.h to target-*/op_helper.c. Move also various other stuff only used in op_helper.c there. Define global env in dyngen-exec.h. For i386, move wrappers for segment and FPU helpers from user-exec.c to op_helper.c. Implement raise_exception_err_env() to handle dynamic CPUState. Move the function declarations to cpu.h since they can be used outside of op_helper.c context. LM32, s390x, UniCore32: remove unused cpu_halted(), regs_to_env() and env_to_regs(). ARM: make raise_exception() static. Convert #include "exec.h" to #include "cpu.h" #include "dyngen-exec.h" and remove now unused target-*/exec.h. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-07-30revamp acpitable parsing and allow to specify complete (headerful) tableMichael Tokarev
This patch almost rewrites acpi_table_add() function (but still leaves it using old get_param_value() interface). The result is that it's now possible to specify whole table (together with a header) in an external file, instead of just data portion, with a new file= parameter, but at the same time it's still possible to specify header fields as before. Now with the checkpatch.pl formatting fixes, thanks to Stefan Hajnoczi for suggestions, with changes from Isaku Yamahata, and with my further refinements.

Multiboot images can specify a bss segment. The boot loader must clear the memory of the bss and ensure that no modules or structures are allocated inside it. Several fields are provided in the Multiboot header that were previously not used properly.

2011-07-29showing a splash picture when startwayne
Added options to let qemu transfer two configuration files to bios: "bootsplash.bmp" and "etc/boot-menu-wait", which could be specified by command -boot splash=P,splash-time=T P is jpg/bmp file name or an absolute path, T have a max value of 0xffff, unit is ms. With these two options, if user invoke qemu with menu=on option, then a splash picture would be showed in a given time. For example: qemu -boot menu=on,splash=/root/boot.bmp,splash-time=5000 would make boot.bmp shown as a brand with 5 seconds in the booting up process.

2011-07-26xen: implement unplug protocol in xen_platformStefano Stabellini
The unplug protocol is necessary to support PV drivers in the guest: the drivers expect to be able to "unplug" emulated disks and nics before initializing the Xen PV interfaces. It is responsibility of the guest to make sure that the unplug is done before the emulated devices or the PV interface start to be used. We use pci_for_each_device to walk the PCI bus, identify the devices and disks that we want to disable and dynamically unplug them. Changes in v2: - use PCI_CLASS constants; - replace pci_unplug_device with qdev_unplug; - do not import hw/ide/internal.h in xen_platform.c; Changes in v3: - introduce piix3-ide-xen, that support hot-unplug; - move the unplug code to hw/ide/piix.c; - just call qdev_unplug from xen_platform.c to unplug the IDE disks; Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Acked-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2011-07-26xen: make xen_enabled even more cleverAlexander Graf
When using xen_enabled() we're currently only checking if xen is enabled at all during the build. But what if you want to build multiple targets out of which only one can potentially run xen code? That means that for generic code we'll still have to fall back to the variable and potentially slow the code down, but it's not as important as that is mostly xen device emulation which is not touched for non-xen targets. The target specific code however can with this patch see that it's unable to ever execute xen code. We can thus always return 0 on xen_enabled(), giving gcc enough hints to evict the mapcache code from the target memory management code.
