virtio-console: qdev conversion, new virtio-serial-bus This commit converts the virtio-console device to create a new virtio-serial bus that can host console and generic serial ports. The file hosting this code is now called virtio-serial-bus.c. The virtio console is now a very simple qdev device that sits on the virtio-serial-bus and communicates between the bus and qemu's chardevs. This commit also includes a few changes to the virtio backing code for pci and s390 to spawn the virtio-serial bus. As a result of the qdev conversion, we get rid of a lot of legacy code. The old-style way of instantiating a virtio console using -virtioconsole ... is maintained, but the new, preferred way is to use -device virtio-serial -device virtconsole,chardev=... With this commit, multiple devices as well as multiple ports with a single device can be supported. For multiple ports support, each port gets an IO vq pair. Since the guest needs to know in advance how many vqs a particular device will need, we have to set this number as a property of the virtio-serial device and also as a config option. In addition, we also spawn a pair of control IO vqs. This is an internal channel meant for guest-host communication for things like port open/close, sending port properties over to the guest, etc. This commit is a part of a series of other commits to get the full implementation of multiport support. Future commits will add other support as well as ride on the savevm version that we bump up here. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Support default block interfaces per QEMUMachine There are QEMUMachines that have neither IF_IDE nor IF_SCSI as a default/standard interface to their block devices / drives. Therefore, this patch introduces a new field default_block_type per QEMUMachine struct. The prior use_scsi field becomes thereby obsolete and is replaced through .default_block_type = IF_SCSI. This patch also changes the default for s390x to IF_VIRTIO and removes an early hack that converts IF_IDE drives. Other parties have already claimed interest (e.g. IF_SD for exynos) To create a sane default, for machines that dont specify a default_block_type, this patch makes IF_IDE = 0 and IF_NONE = 1. I checked all users of IF_NONE (blockdev.c and ww/device-hotplug.c) as well as IF_IDE and it seems that it is ok to change the defines - in other words, I found no obvious (to me) assumption in the code regarding IF_NONE==0. IF_NONE is only set if there is an explicit if=none. Without if=* the interface becomes IF_DEFAULT. I would suggest to have some additional care, e.g. by letting this patch sit some days in the block tree.

chardev: mark the calls that allow an implicit mux monitor This is mostly for readability of the code. Let's make it clear which callers can create an implicit monitor when the chardev is muxed. This will also enforce a safer behaviour, as we don't really support creating monitor anywhere/anytime at the moment. Add an assert() to make sure the programmer explicitely wanted that behaviour. There are documented cases, such as: -serial/-parallel/-virtioconsole and to less extent -debugcon. Less obvious and questionable ones are -gdb, SLIRP -guestfwd and Xen console. Add a FIXME note for those, but keep the support for now. Other qemu_chr_new() callers either have a fixed parameter/filename string or do not need it, such as -qtest: * qtest.c: qtest_init() Afaik, only used by tests/libqtest.c, without mux. I don't think we support it outside of qemu testing: drop support for implicit mux monitor (qemu_chr_new() call: no implicit mux now). * hw/ All with literal @filename argument that doesn't enable mux monitor. * tests/ All with @filename argument that doesn't enable mux monitor. On a related note, the list of monitor creation places: - the chardev creators listed above: all from command line (except perhaps Xen console?) - -gdb & hmp gdbserver will create a "GDB monitor command" chardev that is wired to an HMP monitor. - -mon command line option From this short study, I would like to think that a monitor may only be created in the main thread today, though I remain skeptical :) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com>

well-defined listing order for machine types Commit 261747f1 ("vl: Use MachineClass instead of global QEMUMachine list") broke the ordering of the machine types in the user-visible output of qemu-system-XXXX -M \? This occurred because registration was rebased from a manually maintained linked list to GLib hash tables: qemu_register_machine() type_register() type_register_internal() type_table_add() g_hash_table_insert() and because the listing was rebased accordingly, from the traversal of the list to the traversal of the hash table (rendered as an ad-hoc list): machine_parse() object_class_get_list(TYPE_MACHINE) object_class_foreach() g_hash_table_foreach() The current order is a "random" one, for practical purposes, which is annoying for users. Introduce new members QEMUMachine.family and MachineClass.family, allowing machine types to be "clustered". Introduce a comparator function that establishes a total ordering between machine types, ordering machine types in the same family next to each other. In machine_parse(), list the supported machine types sorted with the comparator function. The comparator function: - sorts whole families before standalone machine types, - sorts whole families between each other in alphabetically increasing order, - sorts machine types inside the same family in alphabetically decreasing order, - sorts standalone machine types between each other in alphabetically increasing order. After this patch, all machine types are considered standalone, and accordingly, the output is alphabetically ascending. This will be refined in the following patches.

Coccinelle script: @rule1 forall@ identifier fun, err, errp, lbl; expression list args, args2; binary operator op; constant c1, c2; symbol false; @@ if ( ( - fun(args, &err, args2) + fun(args, errp, args2) | - !fun(args, &err, args2) + !fun(args, errp, args2) | - fun(args, &err, args2) op c1 + fun(args, errp, args2) op c1 ) ) { ... when != err when != lbl: when strict - error_propagate(errp, err); ... when != err ( return; | return c2; | return false; ) } @rule2 forall@ identifier fun, err, errp, lbl; expression list args, args2; expression var; binary operator op; constant c1, c2; symbol false; @@ - var = fun(args, &err, args2); + var = fun(args, errp, args2); ... when != err if ( ( var | !var | var op c1 ) ) { ... when != err when != lbl: when strict - error_propagate(errp, err); ... when != err ( return; | return c2; | return false; | return var; ) } @depends on rule1 || rule2@ identifier err; @@ - Error *err = NULL; ... when != err Not exactly elegant, I'm afraid. The "when != lbl:" is necessary to avoid transforming if (fun(args, &err)) { goto out } ... out: error_propagate(errp, err); even though other paths to label out still need the error_propagate(). For an actual example, see sclp_realize(). Without the "when strict", Coccinelle transforms vfio_msix_setup(), incorrectly. I don't know what exactly "when strict" does, only that it helps here. The match of return is narrower than what I want, but I can't figure out how to express "return where the operand doesn't use @err". For an example where it's too narrow, see vfio_intx_enable(). Silently fails to convert hw/arm/armsse.c, because Coccinelle gets confused by ARMSSE being used both as typedef and function-like macro there. Converted manually. Line breaks tidied up manually. One nested declaration of @local_err deleted manually. Preexisting unwanted blank line dropped in hw/riscv/sifive_e.c.

vl: Fix -drive / -blockdev persistent reservation management 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. Recent commit cda4aa9a5a "vl: Create block backends before setting machine properties" was such a rejigger. Block backends are now created before "delayed" objects. This broke persistent reservation management. Reproducer: $ qemu-system-x86_64 -object pr-manager-helper,id=pr-helper0,path=/tmp/pr-helper0.sock-drive -drive file=/dev/mapper/crypt,file.pr-manager=pr-helper0,format=raw,if=none,id=drive-scsi0-0-0-2 qemu-system-x86_64: -drive file=/dev/mapper/crypt,file.pr-manager=pr-helper0,format=raw,if=none,id=drive-scsi0-0-0-2: No persistent reservation manager with id 'pr-helper0' The delayed pr-manager-helper object is created too late for use by -drive or -blockdev. Normal objects are still created in time. pr-manager-helper has always been a delayed object (commit 7c9e527659 "scsi, file-posix: add support for persistent reservation management"). Turns out there's no real reason for that. Make it a normal object.

vl/s390x: fixup ram sizes for compat machines Older QEMU versions did fixup the ram size to match what can be reported via sclp. We need to mimic this behaviour for machine types 4.2 and older to not fail on inbound migration for memory sizes that do not fit. Old machines with proper aligned memory sizes are not affected. Alignment table: VM size (<=) | Alignment -------------------------- 1020M | 1M 2040M | 2M 4080M | 4M 8160M | 8M 16320M | 16M 32640M | 32M 65280M | 64M 130560M | 128M 261120M | 256M 522240M | 512M 1044480M | 1G 2088960M | 2G 4177920M | 4G 8355840M | 8G Suggested action is to replace unaligned -m value with a suitable aligned one or if a change to a newer machine type is possible, use a machine version >= 5.0. A future version might remove the compatibility handling. For machine types >= 5.0 we can simply use an increment size of 1M and use the full range of increment number which allows for all possible memory sizes. The old limitation of having a maximum of 1020 increments was added for standby memory, which we no longer support. With that we can now support even weird memory sizes like 10001234 MB. As we no longer fixup maxram_size as well, make other users use ram_size instead. Keep using maxram_size when setting the maximum ram size in KVM, as that will come in handy in the future when supporting memory hotplug (in contrast, storage keys and storage attributes for hotplugged memory will have to be migrated per RAM block in the future).

qom: Drop parameter @errp of object_property_add() & friends The only way object_property_add() can fail is when a property with the same name already exists. Since our property names are all hardcoded, failure is a programming error, and the appropriate way to handle it is passing &error_abort. Same for its variants, except for object_property_add_child(), which additionally fails when the child already has a parent. Parentage is also under program control, so this is a programming error, too. We have a bit over 500 callers. Almost half of them pass &error_abort, slightly fewer ignore errors, one test case handles errors, and the remaining few callers pass them to their own callers. The previous few commits demonstrated once again that ignoring programming errors is a bad idea. Of the few ones that pass on errors, several violate the Error API. The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. ich9_pm_add_properties(), sparc32_ledma_realize(), sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize() are wrong that way. When the one appropriate choice of argument is &error_abort, letting users pick the argument is a bad idea. Drop parameter @errp and assert the preconditions instead. There's one exception to "duplicate property name is a programming error": the way object_property_add() implements the magic (and undocumented) "automatic arrayification". Don't drop @errp there. Instead, rename object_property_add() to object_property_try_add(), and add the obvious wrapper object_property_add().

vl.c: fix migration failure for 3.1 and older machine types Migration from QEMU(v4.0) fails when using 3.1 or older machine type. For example if one attempts to migrate QEMU-2.12 started as qemu-system-ppc64 -nodefaults -M pseries-2.12 -m 4096 -mem-path /tmp/ to current master, it will fail with qemu-system-ppc64: Unknown ramblock "ppc_spapr.ram", cannot accept migration qemu-system-ppc64: error while loading state for instance 0x0 of device 'ram' qemu-system-ppc64: load of migration failed: Invalid argument Caused by 900c0ba373 commit which switches main RAM allocation to memory backends and the fact in 3.1 and older QEMU, backends used full[***] QOM path as memory region name instead of backend's name. That was changed after 3.1 to use prefix-less names by default (fa0cb34d22) for new machine types. *** effectively makes main RAM memory region names defined by MachineClass::default_ram_id being altered with '/objects/' prefix and therefore migration fails as old QEMU sends prefix-less name while new QEMU expects name with prefix when using 3.1 and older machine types. Fix it by forcing implicit[1] memory backend to always use prefix-less names for its memory region by setting 'x-use-canonical-path-for-ramblock-id' property to false. 1) i.e. memory backend created by compat glue which maps -m/-mem-path/-mem-prealloc/default RAM size into appropriate backend type/options to match old CLI format.

vl: Fix -boot order and once regressions, and related bugs Option "once" sets up a different boot order just for the initial boot. Boot order reverts back to normal on reset. Option "order" changes the normal boot order. The reversal is implemented by reset handler restore_boot_devices(), which takes the boot order to revert to as argument. restore_boot_devices() does nothing on its first call, because that must be the initial machine reset. On its second call, it changes the boot order back, and unregisters itself. Because we register the handler right when -boot gets parsed, we can revert to an incorrect normal boot order, and multiple -boot can interact in funny ways. Here's how things work without -boot once or order: * boot_devices is "". * main() passes machine->boot_order to to machine->init(), because boot_devices is "". machine->init() configures firmware accordingly. For PC machines, machine->boot_order is "cad", and pc_cmos_init() writes it to RTC CMOS, where SeaBIOS picks it up. Now consider -boot order=: * boot_devices is "". * -boot order= sets boot_devices to "" (no change). * main() passes machine->boot_order to to machine->init(), because boot_devices is "", as above. Bug: -boot order= has no effect. Broken in commit e4ada29e. Next, consider -boot once=a: * boot_devices is "". * -boot once=a registers restore_boot_devices() with argument "", and sets boot_devices to "a". * main() passes boot_devices "a" to machine->init(), which configures firmware accordingly. For PC machines, pc_cmos_init() writes the boot order to RTC CMOS. * main() calls qemu_system_reset(). This runs reset handlers. - restore_boot_devices() gets called with argument "". Does nothing, because it's the first call. * Machine boots, boot order is "a". * Machine resets (e.g. monitor command). Reset handlers run. - restore_boot_devices() gets called with argument "". Calls qemu_boot_set("") to reconfigure firmware. For PC machines, pc_boot_set() writes it into RTC CMOS. Reset handler unregistered. Bug: boot order reverts to "" instead of machine->boot_order. The actual boot order depends on how firmware interprets "". Broken in commit e4ada29e. Next, consider -boot once=a -boot order=c: * boot_devices is "". * -boot once=a registers restore_boot_devices() with argument "", and sets boot_devices to "a". * -boot order=c sets boot_devices to "c". * main() passes boot_devices "c" to machine->init(), which configures firmware accordingly. For PC machines, pc_cmos_init() writes the boot order to RTC CMOS. * main() calls qemu_system_reset(). This runs reset handlers. - restore_boot_devices() gets called with argument "". Does nothing, because it's the first call. * Machine boots, boot order is "c". Bug: it should be "a". I figure this has always been broken. * Machine resets (e.g. monitor command). Reset handlers run. - restore_boot_devices() gets called with argument "". Calls qemu_boot_set("") to reconfigure firmware. For PC machines, pc_boot_set() writes it into RTC CMOS. Reset handler unregistered. Bug: boot order reverts to "" instead of "c". I figure this has always been broken, just differently broken before commit e4ada29e. Next, consider -boot once=a -boot once=b -boot once=c: * boot_devices is "". * -boot once=a registers restore_boot_devices() with argument "", and sets boot_devices to "a". * -boot once=b registers restore_boot_devices() with argument "a", and sets boot_devices to "b". * -boot once=c registers restore_boot_devices() with argument "b", and sets boot_devices to "c". * main() passes boot_devices "c" to machine->init(), which configures firmware accordingly. For PC machines, pc_cmos_init() writes the boot order to RTC CMOS. * main() calls qemu_system_reset(). This runs reset handlers. - restore_boot_devices() gets called with argument "". Does nothing, because it's the first call. - restore_boot_devices() gets called with argument "a". Calls qemu_boot_set("a") to reconfigure firmware. For PC machines, pc_boot_set() writes it into RTC CMOS. Reset handler unregistered. - restore_boot_devices() gets called with argument "b". Calls qemu_boot_set("b") to reconfigure firmware. For PC machines, pc_boot_set() writes it into RTC CMOS. Reset handler unregistered. * Machine boots, boot order is "b". Bug: should really be "c", because that came last, and for all other -boot options, the last one wins. I figure this was broken some time before commit 37905d6a, and fixed there only for a single occurence of "once". * Machine resets (e.g. monitor command). Reset handlers run. - restore_boot_devices() gets called with argument "". Calls qemu_boot_set("") to reconfigure firmware. For PC machines, pc_boot_set() writes it into RTC CMOS. Reset handler unregistered. Same bug as above: boot order reverts to "" instead of machine->boot_order. Fix by acting upon -boot options order, once and menu only after option parsing is complete, and the machine is known. This is how the other -boot options work already.

Network backend creation is switched to qemu_opts_parse. qemu_opts_set is now only used on merge-lists QemuOptsList... except in the testcase, which is changed to use a merge-list QemuOptsList. With this change we can also remove the id parameter. With the parameter always NULL, we know that qemu_opts_create cannot fail and can pass &error_abort to it.

DisplayState interface change (Stefano Stabellini) This patch changes the DisplayState interface adding support for multiple frontends at the same time (sdl and vnc) and implements most of the benefit of the shared_buf patch without the added complexity. Currently DisplayState is managed by sdl (or vnc) and sdl (or vnc) is also responsible for allocating the data and setting the depth. Vga.c (or another backend) will do any necessary conversion. The idea is to change it so that is vga.c (or another backend) together with console.c that fully manage the DisplayState interface allocating data and setting the depth (either 16 or 32 bit, if the guest uses a different resolution or is in text mode, vga.c (or another backend) is in charge of doing the conversion seamlessly). The other idea is that DisplayState supports *multiple* frontends like sdl and vnc; each of them can register some callbacks to be called when a display event occurs. The interesting changes are: - the new structures and related functions in console.h and console.c in particular the following functions are very helpful to manage a DisplaySurface: qemu_create_displaysurface qemu_resize_displaysurface qemu_create_displaysurface_from qemu_free_displaysurface - console_select and qemu_console_resize in console.c this two functions manage multiple consoles on a single host display - moving code around in hw/vga.c as for the shared_buf patch this is necessary to be able to handle a dynamic DisplaySurface bpp - changes to vga_draw_graphic in hw/vga.c this is the place where the DisplaySurface buffer is shared with the videoram, when possible; Compared to the last version the only changes are: - do not remove support to dpy_copy in cirrus_vga - change the name of the displaysurface handling functions Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6336 c046a42c-6fe2-441c-8c8c-71466251a162

cli: add --preconfig option This option allows pausing QEMU in the new RUN_STATE_PRECONFIG state, allowing the configuration of QEMU from QMP before the machine jumps into board initialization code of machine_run_board_init() The intent is to allow management to query machine state and additionally configure it using previous query results within one QEMU instance (i.e. eliminate the need to start QEMU twice, 1st to query board specific parameters and 2nd for actual VM start using query results for additional parameters). The new option complements -S option and could be used with or without it. The difference is that -S pauses QEMU when the machine is completely initialized with all devices wired up and ready to execute guest code (QEMU needs only to unpause VCPUs to let guest execute its code), while the "preconfig" option pauses QEMU early before board specific init callback (machine_run_board_init) is executed and allows the configuration of machine parameters which will be used by board init code. When early introspection/configuration is done, command 'exit-preconfig' should be used to exit RUN_STATE_PRECONFIG and transition to the next requested state (i.e. if -S is used then QEMU will pause the second time when board/device initialization is completed or start guest execution if -S isn't provided on CLI) PS: Initially 'preconfig' is planned to be used for configuring numa topology depending on board specified possible cpus layout.

Revert "migration: move only_migratable to MigrationState" 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.
