Hi,
This is the final-ish version of the "SEAMCALL Wrappers" RFC[0], with
all the wrappers extracted out of the corresponding TDX patches.
This version of the series uses u64 only for guest physical addresses
and error return values:
* u64 pfn is replaced by struct page
* u64 level is replaced by int level
* u64 tdr and u64 tdvpr are replaced by structs that contain struct page
for them as well as for tdcs and tdcx.
A couple functions are also moved over from KVM to tdx.h
static inline u64 mk_keyed_paddr(u16 hkid, struct page *page)
static inline int pg_level_to_tdx_sept_level(enum pg_level level)
The plan is to include these in kvm.git together with their first user.
Thanks,
Paolo
