| From | "Kirill A. Shutemov" <> | Subject | [PATCH 10/20] x86/tdx: Convert GET_QUOTE hypercall to use new TDVMCALL macros | Date | Fri, 17 May 2024 17:19:28 +0300 |
| |
Use newly introduced TDVMCALL_0() instead of __tdx_hypercall() to issue GET_QUOTE hypercall.
It cuts code bloat substantially:
Function old new delta tdx_hcall_get_quote 188 76 -112
