From f2c679d4b2c73a95f437c705f960a4af1fa23498 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Tue, 15 Sep 2020 05:49:27 -0700 Subject: : Add Intel Key Locker support Add Intel Key Locker: https://software.intel.com/content/www/us/en/develop/download/intel-key-locker-specification.html support to . Intel Key Locker has 1. KL: AES Key Locker instructions. 2. WIDE_KL: AES wide Key Locker instructions. 3. AESKLE: AES Key Locker instructions are enabled by OS. Applications should use if (CPU_FEATURE_USABLE (KL)) and if (CPU_FEATURE_USABLE (WIDE_KL)) to check if AES Key Locker instructions and AES wide Key Locker instructions are usable. --- manual/platform.texi | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'manual') diff --git a/manual/platform.texi b/manual/platform.texi index 2c145acdc3..95b0ed0642 100644 --- a/manual/platform.texi +++ b/manual/platform.texi @@ -177,6 +177,9 @@ The supported processor features are: @item @code{AES} -- The AES instruction extensions. +@item +@code{AESKLE} -- AES Key Locker instructions are enabled by OS. + @item @code{AMX_BF16} -- Tile computational operations on bfloat16 numbers. @@ -353,6 +356,9 @@ the indirect branch predictor barrier (IBPB). @item @code{INVPCID} -- INVPCID instruction. +@item +@code{KL} -- AES Key Locker instructions. + @item @code{L1D_FLUSH} -- IA32_FLUSH_CMD MSR. @@ -598,6 +604,9 @@ using a TSC deadline value. @item @code{WBNOINVD} -- WBINVD/WBNOINVD instructions. +@item +@code{WIDE_KL} -- AES wide Key Locker instructions. + @item @code{X2APIC} -- x2APIC. -- cgit v1.2.3
