2016-01-18qom: Change object property iterator API contractDaniel P. Berrange
Currently the ObjectProperty iterator API works as follows: ObjectPropertyIterator *iter; iter = object_property_iter_init(obj); while ((prop = object_property_iter_next(iter))) { ... } object_property_iter_free(iter); This has the benefit that the ObjectPropertyIterator struct can be opaque, but has the downside that callers need to explicitly call a free function. It is also not in keeping with iterator style used elsewhere in QEMU/GLib2. This patch changes the API to use stack allocation instead: ObjectPropertyIterator iter; object_property_iter_init(&iter, obj); while ((prop = object_property_iter_next(&iter))) { ... } Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.

2016-01-18qom: Allow properties to be registered against classesDaniel P. Berrange
When there are many instances of a given class, registering properties against the instance is wasteful of resources. The majority of objects have a statically defined list of possible properties, so most of the properties are easily registerable against the class. Only those properties which are conditionally registered at runtime need be recorded against the klass. Registering properties against classes also makes it possible to provide static introspection of QOM - currently introspection is only possible after creating an instance of a class, which severely limits its usefulness. This impl only supports simple scalar properties. It does not attempt to allow child object / link object properties against the class. There are ways to support those too, but it would make this patch more complicated, so it is left as an exercise for the future. There is no equivalent to object_property_del() provided, since classes must be immutable once they are defined. Signed-off-by: Daniel P.

2016-01-18Fix corner-case when using VNC+SASL+SPICEChristophe Fergeau
Similarly to the commit 764eb39d1b6 fixing VNC+SASL+QXL, when starting QEMU with SPICE but no SASL, and at the same time VNC with SASL, then spice_server_init() will get called without a previous call to spice_server_set_sasl_appname(), which will cause cyrus-sasl to try to use /etc/sasl2/spice.conf (spice-server uses "spice" as its default appname) rather than the expected /etc/sasl2/qemu.conf. This commit unconditionally calls spice_server_set_sasl_appname() before calling spice_server_init() in order to use the correct appname even if SPICE without SASL was requested on qemu command line.

2016-01-16target-sparc: Migrate CWP and PIL for SPARC64Peter Maydell
In SPARC32 the env->cwp and env->psrpil state is part of the PSR register, and gets migrated as part of that register. In SPARC64 this state is in separate CWP and PIL registers, but we were not doing anything to migrate those. Add the missing fields to the migration vmstate (which is a migration break, but without these fields migration is completely broken anyway). This change means that trying a save/load of a SPARC64 target at the boot rom prompt now produces a system which at least responds to keyboard input after the restore.

For inbound migration we really want to be able to set the PSR without having any side effects, but cpu_put_psr() calls cpu_check_irqs() which might try to deliver CPU interrupts. Split cpu_put_psr() into the no-side-effect and side-effect parts. This includes reordering the cpu_check_irqs() to the end of cpu_put_psr(), because that function may actually end up calling cpu_interrupt(), which does not seem like a good thing to happen in the middle of updating the PSR.

2016-01-15qemu-char: add logfile facility to all chardev backendsDaniel P. Berrange
Typically a UNIX guest OS will log boot messages to a serial port in addition to any graphical console. An admin user may also wish to use the serial port for an interactive console. A virtualization management system may wish to collect system boot messages by logging the serial port, but also wish to allow admins interactive access. Currently providing such a feature forces the mgmt app to either provide 2 separate serial ports, one for logging boot messages and one for interactive console login, or to proxy all output via a separate service that can multiplex the two needs onto one serial port. While both are valid approaches, they each have their own downsides. The former causes confusion and extra setup work for VM admins creating disk images. The latter places an extra burden to re-implement much of the QEMU chardev backends logic in libvirt or even higher level mgmt apps and adds extra hops in the data transfer path. A simpler approach that is satisfactory for many use cases is to allow the QEMU chardev backends to have a "logfile" property associated with them. $QEMU -chardev socket,host=localhost,port=9000,\ server=on,nowait,id-charserial0,\ logfile=/var/log/libvirt/qemu/test-serial0.log -device isa-serial,chardev=charserial0,id=serial0 This patch introduces a 'ChardevCommon' struct which is setup as a base for all the ChardevBackend types. Ideally this would be registered directly as a base against ChardevBackend, rather than each type, but the QAPI generator doesn't allow that since the ChardevBackend is a non-discriminated union. The ChardevCommon struct provides the optional 'logfile' parameter, as well as 'logappend' which controls whether QEMU truncates or appends (default truncate). Signed-off-by: Daniel P.

2016-01-15nbd-server: Coroutine based negotiationFam Zheng
Create a coroutine in nbd_client_new, so that nbd_send_negotiate doesn't need qemu_set_block(). Handlers need to be set temporarily for csock fd in case the coroutine yields during I/O. With this, if the other end disappears in the middle of the negotiation, we don't block the whole event loop. To make the code clearer, unify all function names that belong to negotiate, so they are less likely to be misused. This is important because we rely on negotiation staying in main loop, as commented in nbd_negotiate_read/write().

For added fun the impl of recv_all is completely missing on Win32. Fortunately there is only a single caller of these methods, the TPM passthrough code, which is only ever compiled on Linux.

2016-01-15dump: allow target to set the page sizeAndrew Jones
This is necessary for targets that don't have TARGET_PAGE_SIZE == real-target-page-size. The target should set the page size to the correct one, if known, or, if not known, to the maximum page size it supports. (No functional change.)

2016-01-15xlnx-zynqmp: Add support for high DDR memory regionsAlistair Francis
The Xilinx ZynqMP SoC and EP108 board supports three memory regions: - A 2GB region starting at 0 - A 32GB region starting at 32GB - A 256GB region starting at 768GB This patch adds support for the first two memory regions, which is automatically created based on the size specified by the QEMU memory command line argument. On hardware the physical memory region is one continuous region, it is then mapped into the three different regions by the DDRC. As we don't model the DDRC this is done at startup by QEMU. The board creates the memory region and then passes that memory region to the SoC. The SoC then maps the memory regions.

2016-01-15target-arm: Use the right MMU index in arm_regime_using_lpae_formatAlvise Rigo
arm_regime_using_lpae_format checks whether the LPAE extension is used for stage 1 translation regimes. MMU indexes not exclusively of a stage 1 regime won't work with this method. In case of ARMMMUIdx_S12NSE0 or ARMMMUIdx_S12NSE1, offset these values by ARMMMUIdx_S1NSE0 to get the right index indicating a stage 1 translation regime. Rename also the function to arm_s1_regime_using_lpae_format and update the comments to reflect the change.

2016-01-14disas/libvixl: Really suppress gcc 4.6.3 sign-compare warningsPeter Maydell
Commit 8acc216b956 attempted to silence some sign-compare warnings in libvixl by adding -Wno-sign-compare to the CFLAGS for the relevant objects. Unfortunately it was ineffective because it was placed before $(QEMU_CFLAGS), so the -Wall in the general flags overrode -Wno-sign-compare rather than vice-versa. Reorder the flags so the warning suppression works. Thanks to Franz-Josef Haider <Franz-Josef.Haider@student.uibk.ac.at> for pointing out what was wrong with the original patch.

We don't want newlines embedded in error messages. This seems to be a common problem with new code so let's try to catch it with checkpatch. This will not catch cases where newlines are inserted into the middle of an existing multi-line statement. But those cases should be rare. Signed-off-by: Jason J.
