Subject: qapi: add query-cpu-definitions command (v2)
X-Git-Tag: qemu-xen-4.3.0-rc1~745^2~2
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=e4e31c6324af480a22bf4150266b278368eaa336;p=qemu-upstream-4.5-testing.git

qapi: add query-cpu-definitions command (v2)

This command attempts to map to the behavior of -cpu ?.  Unfortunately, the
output of this command differs wildly across targets.

To accommodate this, we use a weak symbol to implement a default version of the
command that fails with a QERR_NOT_SUPPORTED error code.  Targets can then
override and implement this command if it makes sense for them.
