Subject: [PATCH v3 03/15] x86/insn: Add Key Locker instructions to the opcode map
Date: Wed, 24 Nov 2021 12:06:48 -0800 [thread overview]
Message-ID: <20211124200700.15888-4-chang.seok.bae@intel.com> (raw)
In-Reply-To: <20211124200700.15888-1-chang.seok.bae@intel.com>
Add the following Key Locker instructions to the opcode map:
LOADIWKEY:
Load an CPU-internal wrapping key.
ENCODEKEY128:
Wrap a 128-bit AES key to a key handle.
ENCODEKEY256:
Wrap a 256-bit AES key to a key handle.
AESENC128KL:
Encrypt a 128-bit block of data using a 128-bit AES key indicated
by a key handle.
AESENC256KL:
Encrypt a 128-bit block of data using a 256-bit AES key indicated
by a key handle.
AESDEC128KL:
Decrypt a 128-bit block of data using a 128-bit AES key indicated
by a key handle.
AESDEC256KL:
Decrypt a 128-bit block of data using a 256-bit AES key indicated
by a key handle.
AESENCWIDE128KL:
Encrypt 8 128-bit blocks of data using a 128-bit AES key indicated
by a key handle.
AESENCWIDE256KL:
Encrypt 8 128-bit blocks of data using a 256-bit AES key indicated
by a key handle.
AESDECWIDE128KL:
Decrypt 8 128-bit blocks of data using a 128-bit AES key indicated
by a key handle.
AESDECWIDE256KL:
Decrypt 8 128-bit blocks of data using a 256-bit AES key indicated
by a key handle.
Details of these instructions can be found in Intel Software Developer's
Manual.

Changes from RFC v1:
* Separated out the LOADIWKEY addition in a new patch.
* Included AES instructions to avoid warning messages when the AES Key
Locker module is built.
