Add smbios type 4 CPU speed check for we added new options to set
smbios type 4 "max speed" and "current speed". The default value
should be 2000 when no option is specified, just as the old version
did.
We add the test case to one machine of each architecture, though it
doesn't really run on aarc

Hi, this patchset was previously posted by my teamate Heyi Guo several
months ago, however we missed the merge window. It is reposted here to
make it an end. Thanks.

Common VM users sometimes care about CPU speed, so we add two new

Common VM users sometimes care about CPU speed, so we add two new
options to allow VM vendors to present CPU speed to their users.
Normally these information can be fetched from host smbios.
Strictly speaking, the "max speed" and "current speed" in type 4
are not really for the max speed and curre

A bit verbose. I shortened it to
A new feature, VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS, has been
added to the vhost-user protocol.
VMs with vhost-user device backends which support this feature will
not be subject to the current max RAM slots limit of 8 and will be able to
hot-add memory as man

Hi Joel Stanley, Andrew Jeffery, Cédric Le Goater,
How to modify it so that QEMU can run 64MB BMC image?
In addition, how to learn the source code of QEMU? Are there any guidelines and
reference documents?
thanks，
Byron
