174 parameter "tsx=" on CPUs which support TSX control. MSR_IA32_TSX_CTRL is used200 Not specifying this option is equivalent to "tsx=off".202 The following combinations of the "tsx_async_abort" and "tsx" are possible. For203 affected platforms tsx=auto is equivalent to tsx=off and the result will be:206 tsx=on tsx_async_abort=full The system will use VERW to clear CPU209 tsx=on tsx_async_abort=full,nosmt As above, cross-thread attacks on SMT211 tsx=on tsx_async_abort=off The system is vulnerable.212 tsx=off tsx_async_abort=full TSX might be disabled if microcode215 tsx=off tsx_async_abort=full,nosmt Ditto216 tsx=off tsx_async_abort=off ditto[all …]
1839 Therefore TSX is not enabled by default (aka tsx=off). An admin1840 might override this decision by tsx=on the command line parameter.1845 This option allows to set the default tsx mode between tsx=on, =off1850 platforms or on if TSX is in use and the security aspect of tsx is not1856 TSX is disabled if possible - equals to tsx=off command line parameter.1861 TSX is always enabled on TSX capable HW - equals the tsx=on command1868 side channel attacks- equals the tsx=auto command line parameter.
