2015-06-23virtio-blk: Use blk_drain() to drain IO requestsAlexander Yarygin
Each call of the virtio_blk_reset() function calls blk_drain_all(), which works for all existing BlockDriverStates, while draining only one is needed. This patch replaces blk_drain_all() by blk_drain() in virtio_blk_reset(). virtio_blk_data_plane_stop() should be called after draining because it restores vblk->complete_request. Cc: "Michael S.

2015-06-23throttle: Check current timers before updating any_timer_armed[]Alberto Garcia
Calling throttle_group_config() cancels all timers from a particular BlockDriverState, so any_timer_armed[] should be updated accordingly. However, with the current code it may happen that a timer is armed in a different BlockDriverState from the same group, so any_timer_armed[] would be set to false in a situation where there is still a timer armed. The consequence is that we might end up with two timers armed. This should not have any noticeable impact however, since all accesses to the ThrottleGroup are protected by a lock, and the situation would become normal again shortly thereafter as soon as all timers have been fired. The correct way to solve this is to check that we're actually cancelling a timer before updating any_timer_armed[].

2015-06-23block: Let bdrv_drain_all() to call aio_poll() for each AioContextAlexander Yarygin
After the commit 9b536adc ("block: acquire AioContext in bdrv_drain_all()") the aio_poll() function got called for every BlockDriverState, in assumption that every device may have its own AioContext. If we have thousands of disks attached, there are a lot of BlockDriverStates but only a few AioContexts, leading to tons of unnecessary aio_poll() calls. This patch changes the bdrv_drain_all() function allowing it find shared AioContexts and to call aio_poll() only for unique ones.

2015-06-22qmp: Wean off qerror_report()Markus Armbruster
The traditional QMP command handler interface int qmp_FOO(Monitor *mon, const QDict *params, QObject **ret_data); doesn't provide for returning an Error object. Instead, the handler is expected to stash it in the monitor with qerror_report(). When we rebased QMP on top of QAPI, we didn't change this interface. Instead, commit 776574d introduced "middle mode" as a temporary aid for converting existing QMP commands to QAPI one by one. More than three years later, we're still using it. Middle mode has two effects: * Instead of the native input marshallers static void qmp_marshal_input_FOO(QDict *, QObject **, Error **) it generates input marshallers conforming to the traditional QMP command handler interface. * It suppresses generation of code to register them with qmp_register_command() This permits giving them internal linkage. As long as we need qmp-commands.hx, we can't use the registry behind qmp_register_command(), so the latter has to stay for now. The former has to go to get rid of qerror_report(). Changing all QMP commands to fit the QAPI mold in one go was impractical back when we started, but by now there are just a few stragglers left: do_qmp_capabilities(), qmp_qom_set(), qmp_qom_get(), qmp_object_add(), qmp_netdev_add(), do_device_add(). Switch middle mode to generate native input marshallers, and adapt the stragglers. Simplifies both the monitor code and the stragglers. Rename do_qmp_capabilities() to qmp_capabilities(), and do_device_add() to qmp_device_add, because that's how QMP command handlers are named today.

2015-06-22QemuOpts: Wean off qerror_report_err()Markus Armbruster
qerror_report_err() is a transitional interface to help with converting existing monitor commands to QMP. It should not be used elsewhere. The only remaining user in qemu-option.c is qemu_opts_parse(). Is it used in QMP context? If not, we can simply replace qerror_report_err() by error_report_err(). The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are clearly not in QMP context. The uses in vl.c aren't either, because the only QMP command handlers there are qmp_query_status() and qmp_query_machines(), and they don't call it. Remaining uses: * drive_def(): Command line -drive and such, HMP drive_add and pci_add * hmp_chardev_add(): HMP chardev-add * monitor_parse_command(): HMP core * tmp_config_parse(): Command line -tpmdev * net_host_device_add(): HMP host_net_add * net_client_parse(): Command line -net and -netdev * qemu_global_option(): Command line -global * vnc_parse_func(): Command line -display, -vnc, default display, HMP change, QMP change.

2015-06-22qdev-monitor: Fix check for full busMarkus Armbruster
Property bus has always been too screwed up to be really usable for values other than plain bus IDs. This just fixes a bug that crept in in commit 1395af6 "qdev: add a maximum device allowed field for the bus." It doesn't always fail when it should: $ qemu-system-x86_64 -nodefaults -device virtio-serial-pci -device virtio-rng-device,bus=pci.0/virtio-serial-pci/virtio-bus Happily plugs the virtio-rng-device into the virtio-bus provided by virtio-serial-pci, even though its only slot is already occupied by a virtio-serial-device. And sometimes fails when it shouldn't: $ qemu-system-x86_64 -nodefaults -device virtio-serial-pci -device virtserialport,bus=virtio-bus/virtio-serial-device Yes, the virtio-bus is full, but the virtio-serial-bus provided by virtio-serial-device isn't, and that's the one we're trying to use. Root cause: we check "bus full" when we resolve the first element of the path. That's the correct one only when it's also the last one. Fix by moving the "bus full" check to right before we return a bus. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>

2015-06-22m68k: fix usp processing on interrupt entry and exception exitGreg Ungerer
The action to potentially switch sp register is not occurring at the correct point in the interrupt entry or exception exit sequences. For the interrupt entry case the sp on entry is used to create the stack exception frame - but this may well be the user stack pointer, since we haven't done the switch yet. Re-order the flow to switch the sp regs then use the current sp to create the exception frame. For the return from exception case the code is unwinding the sp after switching sp registers. But it should always unwind the supervisor sp first, then carry out any required sp switch. Note that these problems don't effect operation unless the user sp bit is set in the CACR register. Only a single sp is used in the default power up state. Previously Linux only used this single sp mode. But modern versions of Linux use the user sp mode now, so we need correct behavior for Linux to work.

Move the hard coded register values to the init function. This also allows the entire reset function to be deleted, as PVR registers are now preserved on reset. The hardcoded PVR0 values can be removed as they are setting the endianness and stack protection, which is already done or invalid.

Move the Microblaze PVR registers to the end of the CPUMBState and preserve them during reset. This is similar to what the QEMU ARM model does with some of it's registers. This allows the Microblaze PVR registers to only be set once at realise instead of constantly at reset.
