Subject: [PATCH 0/3] Add generic MMIO instruction deconding to be used in SEV and TDX
Date: Mon, 18 Oct 2021 18:33:30 +0300 [thread overview]
Message-ID: <20211018153333.8261-1-kirill.shutemov@linux.intel.com> (raw)
Both AMD SEV and Intel TDX has to decode MMIO instruction to be able to
handle MMIO.
Extract insn_decode_mmio() from SEV code. TDX will also use this helper.
Kirill A. Shutemov (3):
x86/insn-eval: Introduce insn_get_modrm_reg_ptr()
x86/insn-eval: Introduce insn_decode_mmio()
x86/sev-es: Use insn_decode_mmio() for MMIO implementation
