2020-03-13migration/throttle: Add throttle-trig-thres migration parameterKeqian Zhu
Currently, if the bytes_dirty_period is more than the 50% of bytes_xfer_period, we start or increase throttling. If we make this percentage higher, then we can tolerate higher dirty rate during migration, which means less impact on guest. The side effect of higher percentage is longer migration time. We can make this parameter configurable to switch between mig- ration time first or guest performance first. The default value is 50 and valid range is 1 to 100.

2020-03-06qemu-storage-daemon: Add --monitor optionKevin Wolf
This adds and parses the --monitor option, so that a QMP monitor can be used in the storage daemon. The monitor offers commands defined in the QAPI schema at storage-daemon/qapi/qapi-schema.json. The --monitor options currently allows to create multiple monitors with the same ID. This part of the interface is considered unstable. We will reject such configurations as soon as we have a design for the monitor subsystem to perform these checks. (In the system emulator, we depend on QemuOpts rejecting duplicate IDs.)

This adds a new QAPI-based monitor_init() function. The existing monitor_init_opts() is rewritten to simply put its QemuOpts parameter into a visitor and pass the resulting QAPI object to monitor_init(). This will cause some change in those error messages for the monitor options in the system emulator that are now generated by the visitor rather than explicitly checked in monitor_init_opts().

2019-12-19hmp: Allow using qdev ID for qemu-io commandKevin Wolf
In order to issue requests on an existing BlockBackend with the 'qemu-io' HMP command, allow specifying the BlockBackend not only with a BlockBackend name, but also with a qdev ID/QOM path for a device that owns the (possibly anonymous) BlockBackend. Because qdev names could be conflicting with BlockBackend and node names, introduce a -d option to explicitly address a device. If the option is not given, a BlockBackend or a node is addressed.

2019-11-19monitor/qmp: resume monitor when clearing its queueWolfgang Bumiller
When a monitor's queue is filled up in handle_qmp_command() it gets suspended. It's the dispatcher bh's job currently to resume the monitor, which it does after processing an event from the queue. However, it is possible for a CHR_EVENT_CLOSED event to be processed before before the bh is scheduled, which will clear the queue without resuming the monitor, thereby preventing the dispatcher from reaching the resume() call. Any new connections to the qmp socket will be accept()ed and show the greeting, but will not respond to any messages sent afterwards (as they will not be read from the still-suspended socket). Fix this by resuming the monitor when clearing a queue which was filled up. Signed-off-by: Wolfgang Bumiller <w.bumiller@proxmox.com> Message-Id: <20191115085914.21287-1-w.bumiller@proxmox.com>
2019-10-26core: replace getpagesize() with qemu_real_host_page_sizeWei Yang
There are three page size in qemu: real host page size host page size target page size All of them have dedicate variable to represent. For the last two, we use the same form in the whole qemu project, while for the first one we use two forms: qemu_real_host_page_size and getpagesize(). qemu_real_host_page_size is defined to be a replacement of getpagesize(), so let it serve the role. [Note] Not fully tested for some arch or device.
