There are actually only 8 functions in total which are simply calling sev_do_cmd(), all other functions calling sev_do_cmd() have a lot of other specific functionality in them.
Those are the earlier - sev_platform_status(), sev_guest_deactivate(), sev_guest_decomission() and sev_guest_df_flush().
And the 4 functions added in this patch - snp_guest_decomission(), snp_guest_df_flush(), snp_guest_page_reclaim(), and snp_guest_dbg_decrypt().
Thanks,
Ashish
