Subject: [PATCH] cpu_map: Add TAA_NO bit for IA32_ARCH_CAPABILITIES MSR
|
|
MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

CVE-2019-11135
|
|
|
|
CPUs with TAA_NO bit of IA32_ARCH_CAPABILITIES MSR set to 1 are not
|
|
vulnerable to TSX Asynchronous Abort and passing this bit to a guest
|
|
may avoid unnecessary mitigations.
