2017-01-27chardev: qom-ifyMarc-André Lureau
Turn Chardev into Object. qemu_chr_alloc() is replaced by the qemu_chardev_new() constructor. It will call qemu_char_open() to open/intialize the chardev with the ChardevCommon *backend settings. The CharDriver::create() callback is turned into a ChardevClass::open() which is called from the newly introduced qemu_chardev_open(). "chardev-gdb" and "chardev-hci" are internal chardev and aren't creatable directly with -chardev. Use a new internal flag to disable them. We may want to use TYPE_USER_CREATABLE interface instead, or perhaps allow -chardev usage. Although in general we keep typename and macros private, unless the type is being used by some other file, in this patch, all types and common helper macros for qemu-char.c are in char.h. This is to help transition now (some types must be declared early, while some aren't shared) and when splitting in several units. This is to be improved later.

Now that we allow CPU hot unplug on a few platforms, we can end up in a situation where we don't have a CPU with index 0. Or at least we could, if we didn't have code to explicitly prohibit unplug of CPU 0. Longer term we want to allow CPU 0 unplug, this patch is an early step in allowing this, by removing an assumption in the monitor code that CPU 0 always exists.

2016-09-19qmp: Hack to keep commands configuration-specificMarc-André Lureau
We currently define QMP commands in two places: the QAPI schema and qmp-commands.hx. The latter is preprocessed, the former is not. We use the preprocessor to suppress configuration-specific commands. For instance, query-spice is only available #ifdef CONFIG_SPICE. QMP command dispatch and query-commands use the qmp-commands.hx definition, and thus obey the #ifdeffery there. Good, because it lets QMP clients probe for available features more easily. query-qmp-schema uses the QAPI schema, and thus lists the configuration-specific commands even when they're unavailable. Not so good. We're about to flip command dispatch and query-commands to the non-middle-mode command registry, which uses the QAPI schema, so we can ditch qmp-commands.hx. To avoid regressing query-commands, arrange for commands that are suppressed with the preprocessor now to be unregistered with that registry. This will keep them unavailable and out of query-commands when we flip command dispatch and query-commands to that registry, exactly as before. This is a hack. The proper solution is to support configuration-specific commands in the QAPI schema. Mark it FIXME.

2016-07-19qapi: Change Netdev into a flat unionEric Blake
This is a mostly-mechanical conversion that creates a new flat union 'Netdev' QAPI type that covers all the branches of the former 'NetClientOptions' simple union, where the branches are now listed in a new 'NetClientDriver' enum rather than generated from the simple union. The existence of a flat union has no change to the command line syntax accepted for new code, and will make it possible for a future patch to switch the QMP command to parse a boxed union for no change to valid QMP; but it does have some ripple effect on the C code when dealing with the new types. While making the conversion, note that the 'NetLegacy' type remains unchanged: it applies only to legacy command line options, and will not be ported to QMP, so it should remain a wrapper around a simple union; to avoid confusion, the type named 'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions' in its place. Then, in the C code, we convert from NetLegacy to Netdev as soon as possible, so that the bulk of the net stack only has to deal with one QAPI type, not two. Note that since the old legacy code always rejected 'hubport', we can just omit that branch from the new 'NetLegacyOptions' simple union.

'qjson.h' is not a QObject subtype; include this file directly in .c files that are using it, rather than abusing qmp/types.h for that purpose.

2016-06-20log: Fix qemu_set_log_filename() error handlingMarkus Armbruster
When qemu_set_log_filename() detects an invalid file name, it reports an error, closes the log file (if any), and starts logging to stderr (unless daemonized or nothing is being logged). This is wrong. Asking for an invalid log file on the command line should be fatal. Asking for one in the monitor should fail without messing up an existing logfile. Fix by converting qemu_set_log_filename() to Error. Pass it &error_fatal, except for hmp_logfile report errors. This also permits testing without a subprocess, so do that.

The bdrv_next() users all leaked the BdrvNextIterator after completing the iteration. Simply changing bdrv_next() to free the iterator before returning NULL at the end of list doesn't work because some callers exit the loop before looking at all BDSes. This patch moves the BdrvNextIterator from the heap to the stack of the caller and switches to a bdrv_first()/bdrv_next() interface for initialising the iterator.

2016-03-30arm: qmp: add query-gic-capabilities interfacePeter Xu
This patch add "query-gic-capabilities" but does not implement it. The command is ARM-only. The command will return a list of GICCapability structs that describes all GIC versions that current QEMU and system support. Libvirt is possibly the first consumer of this new command. Before this patch, a libvirt user can successfully configure all kinds of GIC devices for ARM guests, no matter whether current QEMU/kernel supports them. If the specified GIC version/type is not supported, the user will get an ambiguous "QEMU boot failure" error when trying to start the VM. This is not user-friendly. With this patch, libvirt should be able to query which type (and which version) of GIC device is supported. Using this information, libvirt can warn the user during configuration of guests when specified GIC device type is not supported. Or better, we can just list those versions that we support, and filter out the unsupported ones. For example, if we got the query result: {"return": [{"emulated": false, "version": 3, "kernel": true}, {"emulated": true, "version": 2, "kernel": false}]} then it means that we support emulated GIC version 2 using: qemu-system-aarch64 -M virt,accel=tcg,gic-version=2 ... or KVM-accelerated GIC version 3 using: qemu-system-aarch64 -M virt,accel=kvm,gic-version=3 ... If we specify other explicit GIC versions rather than the above, QEMU will not be able to boot. The community is working on a more generic way to query these kinds of information about valid values of machine properties. However, due to the importance of supporting this specific use case, weecided to first implement this ad-hoc one; then when the generic method is ready, we can move on to that one smoothly.

2016-03-22Replaced get_tick_per_sec() by NANOSECONDS_PER_SECONDRutuja Shah
This patch replaces get_ticks_per_sec() calls with the macro NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec() is then removed. This replacement improves the readability and understandability of code. For example, timer_mod(fdctrl->result_timer, qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50)); NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns matches the unit of the expression on the right side of the plus.
