[PATCH 0/2] *** Enable -cpu <cpu>,help ***

Posted by Dinah Baum 1 year, 1 month ago

This patch series enables printing the CPU
options using '-cpu cpu,help' as requested in
https://gitlab.com/qemu-project/qemu/-/issues/1480

Sample output:
athlon features:
  3dnow=<qbool>
  3dnowext=<qbool>
  3dnowprefetch=<qbool>
  ...

Part 1 is a refactor patch that enables query-cpu-model-expansion
on all architectures, but doesn't implement any additional
feature probing. Currently only arm, i386, and s390x support
full feature probing.

This lays for the groundwork for Part 2 which actually
implements the '<cpu>,help' feature

Limitations:
Currently only 'FULL' expansion queries are implemented since
that's the only type enabled on the architectures that
allow feature probing

Unlike the 'device,help' command, default values aren't
printed

Dinah Baum (2):
  cpu, qapi, target/arm, i386, s390x: Refactor query-cpu-model-expansion
  cpu, qdict, vl: Enable printing options for CPU type
