[Qemu-devel] [PATCH v2 0/6] cpus: make "-cpu cpux, features" global prop
[Qemu-devel] [PATCH v2 0/6] cpus: make "-cpu cpux, features" global properties
Thu, 9 Jun 2016 19:10:57 +0200
- rebase on top of x86-next tree, which shaves off already applied several
and fixed deps on wrong tree (v1 was against my device_add_cpu tree)
- add TODO comments
- set cpu_globals_initialized = true early
- move error_propagate() to the end of x86_cpu_parse_featurestr()
- include "target-i386: Remove xlevel & hv-spinlocks option fixups"
- use Eduardo's version of:
target-i386: cpu: consolidate calls of object_property_parse...
- fix error handling of +-feat
- add comment why +-feat is special
- add comment to remove +-feat static vars
- reuse x86_cpu_class_get_model_name()
Current CLI option -cpu cpux,features serves as template
for all created cpus of type: cpux. However QEMU parses
"features" every time it creates a cpu instance and applies
them to it while doing parsing.
That doesn't work well with -device/device_add infrastructure
as it has no idea about cpu specific hooks that's used for
In order to make -device/device_add utilize "-cpu features"
template convert it into a set of global properties, so that
every new CPU created will have them applied automatically.
That also allows to parse features only once, instread of
doing it for every CPU instance being created.
Git tree for testing:
Eduardo Habkost (1):
target-i386: cpu: consolidate calls of object_property_parse() in
Igor Mammedov (5):
target-i386: print obsolete warnings if +-features are used
target-sparc: cpu: use sparc_cpu_parse_features() directly
cpu: use CPUClass->parse_features() as convertor to global properties
arm: virt: parse cpu_model only once
pc: parse cpu features only once
