Add 'throttle-bps' and 'throttle-ops' limitation to set QoS. The two arguments work with both QEMU command line and QMP command. Example of QEMU command line: -object cryptodev-backend-builtin,id=cryptodev1,throttle-bps=1600,\ throttle-ops=100 Example of QMP command: virsh qemu-monitor-command buster --hmp qom-set /objects/cryptodev1 \ throttle-ops 100 or cancel limitation: virsh qemu-monitor-command buster --hmp qom-set /objects/cryptodev1 \ throttle-ops 0 Reviewed-by: Daniel P.

#
|
|
# This command will get a property from a object model path and return the

|
# value.
|
|
#
|
|
# @path: The path within the object model. There are two forms of supported
|
|
# paths--absolute and partial paths.
|
|
#
|
|
# Absolute paths are derived from the root object and can follow child<>
|
|
# or link<> properties. Since they can follow link<> properties, they
|
|
# can be arbitrarily long. Absolute paths look like absolute filenames
|
|
# and are prefixed with a leading slash.
|
|
#
|
|
# Partial paths look like relative filenames. They do not begin
|
|
# with a prefix. The matching rules for partial paths are subtle but
|
|
# designed to make specifying objects easy. At each level of the
|
|
# composition tree, the partial path is matched as an absolute path.
|
|
# The first match is not returned. At least two matches are searched
|
|
# for. A successful result is only returned if only one match is
|
|
# found. If more than one match is found, a flag is return to
|
|
# indicate that the match was ambiguous.
|
|
#
|
|
# @property: The property name to read
|
|
#
|
|
# Returns: The property value. The type depends on the property
|
|
# type. child<> and link<> properties are returned as #str
|
|
# pathnames. All integer property types (u8, u16, etc) are
|
|
# returned as #int.

|
#
|

# Since: 1.2
