Currently all SEV/SEV-ES functionality is managed through a single
'sev-guest' QOM type. With upcoming support for SEV-SNP, taking this
same approach won't work well since some of the properties/state
managed by 'sev-guest' is not applicable to SEV-SNP, which will instead
rely on a new QOM type with its own set of properties/state.
To prepare for this, this patch moves common state into an abstract
'sev-common' parent type to encapsulate properties/state that are
common to both SEV/SEV-ES and SEV-SNP, leaving only SEV/SEV-ES-specific
properties/state in the current 'sev-guest' type. This should not
affect current behavior or command-line options.
As part of this patch, some related changes are also made:
- a static 'sev_guest' variable is currently used to keep track of
the 'sev-guest' instance. SEV-SNP would similarly introduce an
'sev_snp_guest' static variable. But these instances are now
available via qdev_get_machine()->cgs, so switch to using that
instead and drop the static variable.
- 'sev_guest' is currently used as the name for the static variable
holding a pointer to the 'sev-guest' instance. Re-purpose the name
as a local variable referring the 'sev-guest' instance, and use
that consistently throughout the code so it can be easily
distinguished from sev-common/sev-snp-guest instances.
- 'sev' is generally used as the name for local variables holding a
pointer to the 'sev-guest' instance. In cases where that now points
to common state, use the name 'sev_common'; in cases where that now
points to state specific to 'sev-guest' instance, use the name
'sev_guest'
In order to enable kernel-hashes for SNP, pull it from
SevGuestProperties to its parent SevCommonProperties so
it will be available for both SEV and SNP.
