(Whatever is the reason, is it possible change that part of the code in a separate patch, so the code movement is easier to review?) I have additional comments below about small changes made while moving the code, but they are all minor. > * string properties: changed function signature to conform to form used in > qdev-properties.c > > * extra change is addition of feat2prop() helper to deal with properties > naming using '-' instead of '_'.

Been having a similar question (sorry for not replying yet): Can't we leave my new-style getters and setters in place and invoke them through some glue code from whatever old-style machinery qdev static properties still use? BTW I'm not yet clear on how we should proceed with subclasses and KVM. Proposing we proceed with your properties refactoring after all, then maybe it becomes more clear where the problems are.

Following properties are converted: * vendor * xlevel * custom setter/getter replaced by qdev's DEFINE_PROP_UINT32 * level * custom setter/getter replaced by qdev's DEFINE_PROP_UINT32 * tsc-frequency * stepping * model * family * model-id * check "if (model_id == NULL)" looks unnecessary now, since all builtin model-ids are not NULL and user shouldn't be able to set it NULL (cpumodel string parsing code takes care of it, if feature is specified as "model-id=" on command line, its parsing will result in an empty string as value). * use g_malloc0() instead of g_malloc() in x86_cpuid_get_model_id() Common changes to all properties: * properties code are moved to the top of file, before properties array definition * s/error_set/error_setg/;s/QERR*/with similar message/ * string properties: changed function signature to conform to form used in qdev-properties.c * extra change is addition of feat2prop() helper to deal with properties naming using '-' instead of '_'. Used in this patch for 'model_id' name conversion and converting along the way 'hv-spinlocks', but will be reused in following patches for "hv_*" and +-foo conversions as well. * fix checkpatch error introduced by: d480e1aff2f3d Signed-off-by: Igor Mammedov <imammedo@redhat.com> --- target-i386/cpu.c | 592 ++++++++++++++++++++++++++++------------------------- 1 files changed, 316 insertions(+), 276 deletions(-)
