2019-04-18target: Simplify how the TARGET_cpu_list() printMarkus Armbruster1-1/+1
The various TARGET_cpu_list() take an fprintf()-like callback and a FILE * to pass to it. Their callers (vl.c's main() via list_cpus(), bsd-user/main.c's main(), linux-user/main.c's main()) all pass fprintf() and stdout. Thus, the flexibility provided by the (rather tiresome) indirection isn't actually used. Drop the callback, and call qemu_printf() instead. Calling printf() would also work, but would make the code unsuitable for monitor context without making it simpler.

2019-04-17log: Make glib logging go through QEMUChristophe Fergeau1-1/+1
This commit adds a error_init() helper which calls g_log_set_default_handler() so that glib logs (g_log, g_warning, ...) are handled similarly to other QEMU logs. This means they will get a timestamp if timestamps are enabled, and they will go through the HMP monitor if one is configured. This commit also adds a call to error_init() to the binaries installed by QEMU. Since error_init() also calls error_set_progname(), this means that *-linux-user, *-bsd-user and qemu-pr-helper messages output with error_report, info_report, ... will slightly change: they will be prefixed by the binary name. glib debug messages are enabled through G_MESSAGES_DEBUG similarly to the glib default log handler. At the moment, this change will mostly impact SPICE logging if your spice version is >= 0.14.1. With older spice versions, this is not going to work as expected, but will not have any ill effect, so this call is not conditional on the SPICE version.

2019-04-02Revert "migration: move only_migratable to MigrationState"Markus Armbruster1-7/+2
This reverts commit 3df663e575f1876d7f3bc684f80e72fca0703d39. This reverts commit b605c47b57b58e61a901a50a0762dccf43d94783. Command line option --only-migratable is for disallowing any configuration that can block migration. Initially, --only-migratable set global variable @only_migratable. Commit 3df663e575 "migration: move only_migratable to MigrationState" replaced it by MigrationState member @only_migratable. That was a mistake. First, it doesn't make sense on the design level. MigrationState captures the state of an individual migration, but --only-migratable isn't a property of an individual migration, it's a restriction on QEMU configuration. With fault tolerance, we could have several migrations at once. --only-migratable would certainly protect all of them. Storing it in MigrationState feels inappropriate. Second, it contributes to a dependency cycle that manifests itself as a bug now. Putting @only_migratable into MigrationState means its available only after migration_object_init(). We can't set it before migration_object_init(), so we delay setting it with a global property (this is fixup commit b605c47b57 "migration: fix handling for --only-migratable"). We can't get it before migration_object_init(), so anything that uses it can only run afterwards. Since migrate_add_blocker() needs to obey --only-migratable, any code adding migration blockers can run only afterwards. This contributes to the following dependency cycle: * configure_blockdev() must run before machine_set_property() so machine properties can refer to block backends * machine_set_property() before configure_accelerator() so machine properties like kvm-irqchip get applied * configure_accelerator() before migration_object_init() so that Xen's accelerator compat properties get applied. * migration_object_init() before configure_blockdev() so configure_blockdev() can add migration blockers The cycle was closed when recent commit cda4aa9a5a0 "Create block backends before setting machine properties" added the first dependency, and satisfied it by violating the last one. Broke block backends that add migration blockers. Moving @only_migratable into MigrationState was a mistake. Revert it. This doesn't quite break the "migration_object_init() before configure_blockdev() dependency, since migrate_add_blocker() still has another dependency on migration_object_init(). To be addressed the next commit. Note that the reverted commit made -only-migratable sugar for -global migration.only-migratable=on below the hood. Documentation has only ever mentioned -only-migratable. This commit removes the arcane & undocumented alternative to -only-migratable again. Nobody should be using it.

This reverts commit e60483f2f8498ae08ae79ca4c6fb03a3317f5e1e. Recent commit cda4aa9a5a0 moved block backend creation before machine property evaluation. This broke block backends registering migration blockers. Commit e60483f2f84 fixed it by moving migration object creation before block backend creation. This broke migration with Xen. Turns out we need to configure the accelerator before we create the migration object so that Xen's accelerator compat properties get applied. Revert the flawed commit. This fixes the Xen regression, but brings back the block backend regression. The next commits will fix it again.

2019-03-11vl: Create block backends before setting machine propertiesMarkus Armbruster1-2/+7
qemu-system-FOO's main() acts on command line arguments in its own idiosyncratic order. There's not much method to its madness. Whenever we find a case where one kind of command line argument needs to refer to something created for another kind later, we rejigger the order. Block devices get created long after machine properties get processed. Therefore, block device machine properties can be created, but not set. No such properties exist. But the next commit will create some. Time to rejigger again: create block devices earlier.

2019-03-11sysbus: Fix latent bug with onboard devicesMarkus Armbruster1-0/+4
The first call of sysbus_get_default() creates the main system bus and stores it in QOM as "/machine/unattached/sysbus". This must not happen before main() creates "/machine", or else container_get() would "helpfully" create it as "container" object, and the real creation of "/machine" would later abort with "attempt to add duplicate property 'machine' to object (type 'container')". Has been that way ever since we wired up busses in QOM (commit f968fc6892d, v1.2.0). I believe the bug is latent. I got it to bite by trying to qdev_create() a sysbus device from a machine's .instance_init() method. The fix is obvious: store the main system bus in QOM right after creating "/machine".

2019-03-11qdev: Fix latent bug with compat_props and onboard devicesMarkus Armbruster1-0/+1
Compatibility properties started life as a qdev property thing: we supported them only for qdev properties, and implemented them with the machinery backing command line option -global. Recent commit fa0cb34d221 put them to use (tacitly) with memory backend objects (subtypes of TYPE_MEMORY_BACKEND). To make that possible, we first moved the work of applying them from the -global machinery into TYPE_DEVICE's .instance_post_init() method device_post_init(), in commits ea9ce8934c5 and b66bbee39f6, then made it available to TYPE_MEMORY_BACKEND's .instance_post_init() method host_memory_backend_post_init() as object_apply_compat_props(), in commit 1c3994f6d2a. Note the code smell: we now have function name starting with object_ in hw/core/qdev.c. It has to be there rather than in qom/, because it calls qdev_get_machine() to find the current accelerator's and machine's compat_props. Turns out calling qdev_get_machine() there is problematic. If we qdev_create() from a machine's .instance_init() method, we call device_post_init() and thus qdev_get_machine() before main() can create "/machine" in QOM. qdev_get_machine() tries to get it with container_get(), which "helpfully" creates it as "container" object, and returns that. object_apply_compat_props() tries to paper over the problem by doing nothing when the value of qdev_get_machine() isn't a TYPE_MACHINE. But the damage is done already: when main() later attempts to create the real "/machine", it fails with "attempt to add duplicate property 'machine' to object (type 'container')", and aborts. Since no machine .instance_init() calls qdev_create() so far, the bug is latent. But since I want to do that, I get to fix the bug first. Observe that object_apply_compat_props() doesn't actually need the MachineState, only its the compat_props member of its MachineClass and AccelClass. This permits a simple fix: register MachineClass and AccelClass compat_props with the object_apply_compat_props() machinery right after these classes get selected. This is actually similar to how things worked before commits ea9ce8934c5 and b66bbee39f6, except we now register much earlier. The old code registered them only after the machine's .instance_init() ran, which would've broken compatibility properties for any devices created there.

Audio drivers now get an Audiodev * as config paramters, instead of the global audio_option structs. There is some code in audio/audio_legacy.c that converts the old environment variables to audiodev options (this way backends do not have to worry about legacy options). It also contains a replacement of -audio-help, which prints out the equivalent -audiodev based config of the currently specified environment variables. Note that backends are not updated and still rely on environment variables. Also note that (due to moving try-poll from global to backend specific option) currently ALSA and OSS will always try poll mode, regardless of environment variables or -audiodev options.

2019-03-11hw/display: Add basic ATI VGA emulationBALATON Zoltan1-0/+1
At least two machines, the PPC mac99 and MIPS fulong2e, have an ATI gfx chip by default (Rage 128 Pro and M6/RV100 respectively) and guests running on these and the PMON2000 firmware of the fulong2e expect this to be available. Fortunately these are very similar chips so they can be mostly emulated in the same device model. This patch adds basic emulation of these ATI VGA chips. While this is incomplete and currently only enough to run the MIPS firmware and get framebuffer output with Linux, it allows the fulong2e board to work more like the real hardware and having it in QEMU in this state provides a way to experiment with it and allows others to contribute to improve it. It is compiled for all archs but only the fulong2e (which currently has no display output at all) is set to use it by default (in a separate patch).

Currently we cleanup the migration object as we exit main after the main_loop finishes; however if there's a migration running things get messy and we can end up with the migration thread still trying to access freed structures. We now take a ref to the object around the migration thread itself, so the act of dropping the ref during exit doesn't cause us to lose the state until the thread quits. Cancelling the migration during migration also tries to get the thread to quit. We do this a bit earlier; so hopefully migration gets out of the way before all the devices etc are freed.

2019-01-11qemu/queue.h: leave head structs anonymous unless necessaryPaolo Bonzini1-1/+1
Most list head structs need not be given a name. In most cases the name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV or reverse iteration, but this does not apply to lists of other kinds, and even for QTAILQ in practice this is only rarely needed. In addition, we will soon reimplement those macros completely so that they do not need a name for the head struct. So clean up everything, not giving a name except in the rare case where it is necessary. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2019-01-11accel: Improve selection of the default acceleratorThomas Huth1-1/+1
When compiling with "--disable-tcg", we currently still use "tcg" as default accelerator. "kvm" should be used in this case instead. Also, some downstream distros provide QEMU binaries which have "kvm" in their names (e.g. "qemu-kvm" on RHEL or "kvm" on Ubuntu) that use KVM by default - and some users might want to do something similar with upstream binaries, too. Accomodate them by using "kvm:tcg" as default when we detect such a binary name.

2018-12-18qmp hmp: Make system_wakeup check wake-up support and run stateDaniel Henrique Barboza1-2/+4
The qmp/hmp command 'system_wakeup' is simply a direct call to 'qemu_system_wakeup_request' from vl.c. This function verifies if runstate is SUSPENDED and if the wake up reason is valid before proceeding. However, no error or warning is thrown if any of those pre-requirements isn't met. There is no way for the caller to differentiate between a successful wakeup or an error state caused when trying to wake up a guest that wasn't suspended. This means that system_wakeup is silently failing, which can be considered a bug. Adding error handling isn't an API break in this case - applications that didn't check the result will remain broken, the ones that check it will have a chance to deal with it. Adding to that, the commit before previous created a new QMP API called query-current-machine, with a new flag called wakeup-suspend-support, that indicates if the guest has the capability of waking up from suspended state. Although such guest will never reach SUSPENDED state and erroring it out in this scenario would suffice, it is more informative for the user to differentiate between a failure because the guest isn't suspended versus a failure because the guest does not have support for wake up at all. All this considered, this patch changes qmp_system_wakeup to check if the guest is capable of waking up from suspend, and if it is suspended. After this patch, this is the output of system_wakeup in a guest that does not have wake-up from suspend support (ppc64): (qemu) system_wakeup wake-up from suspend is not supported by this guest (qemu) And this is the output of system_wakeup in a x86 guest that has the support but isn't suspended: (qemu) system_wakeup Unable to wake up: guest is not in suspended state (qemu) Reported-by: Balamuruhan S <bala24@linux.vnet.ibm.com> Signed-off-by: Daniel Henrique Barboza <danielhb413@gmail.com> Message-Id: <20181205194701.17836-4-danielhb413@gmail.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Acked-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Michael S.

2018-12-18qmp: query-current-machine with wakeup-suspend-supportDaniel Henrique Barboza1-0/+19
When issuing the qmp/hmp 'system_wakeup' command, what happens in a nutshell is: - qmp_system_wakeup_request set runstate to RUNNING, sets a wakeup_reason and notify the event - in the main_loop, all vcpus are paused, a system reset is issued, all subscribers of wakeup_notifiers receives a notification, vcpus are then resumed and the wake up QAPI event is fired Note that this procedure alone doesn't ensure that the guest will awake from SUSPENDED state - the subscribers of the wake up event must take action to resume the guest, otherwise the guest will simply reboot. At this moment, only the ACPI machines via acpi_pm1_cnt_init and xen_hvm_init have wake-up from suspend support. However, only the presence of 'system_wakeup' is required for QGA to support 'guest-suspend-ram' and 'guest-suspend-hybrid' at this moment. This means that the user/management will expect to suspend the guest using one of those suspend commands and then resume execution using system_wakeup, regardless of the support offered in system_wakeup in the first place. This patch creates a new API called query-current-machine [1], that holds a new flag called 'wakeup-suspend-support' that indicates if the guest supports wake up from suspend via system_wakeup. The machine is considered to implement wake-up support if a call to a new 'qemu_register_wakeup_support' is made during its init, as it is now being done inside acpi_pm1_cnt_init and xen_hvm_init. This allows for any other machine type to declare wake-up support regardless of ACPI state or wakeup_notifiers subscription, making easier for newer implementations that might have their own mechanisms in the future. This is the expected output of query-current-machine when running a x86 guest: {"execute" : "query-current-machine"} {"return": {"wakeup-suspend-support": true}} Running the same x86 guest, but with the --no-acpi option: {"execute" : "query-current-machine"} {"return": {"wakeup-suspend-support": false}} This is the output when running a pseries guest: {"execute" : "query-current-machine"} {"return": {"wakeup-suspend-support": false}} With this extra tool, management can avoid situations where a guest that does not have proper suspend/wake capabilities ends up in inconsistent state (e.g. https://github.com/open-power-host-os/qemu/issues/31). [1] the decision of creating the query-current-machine API is based on discussions in the QEMU mailing list where it was decided that query-target wasn't a proper place to store the wake-up flag, neither was query-machines because this isn't a static property of the machine object. This new API can then be used to store other dynamic machine properties that are scattered around the code ATM.
