A Dtsx_async_abort.rst181 parameter "tsx=" on CPUs which support TSX control. MSR_IA32_TSX_CTRL is used
207 Not specifying this option is equivalent to "tsx=off".
209 The following combinations of the "tsx_async_abort" and "tsx" are possible. For
210 affected platforms tsx=auto is equivalent to tsx=off and the result will be:
213 tsx=on tsx_async_abort=full The system will use VERW to clear CPU
218 tsx=on tsx_async_abort=off The system is vulnerable.
219 tsx=off tsx_async_abort=full TSX might be disabled if microcode
222 tsx=off tsx_async_abort=full,nosmt Ditto
223 tsx=off tsx_async_abort=off ditto
229 "tsx" command line argument has no effect.

A DKconfig1904 Therefore TSX is not enabled by default (aka tsx=off). An admin
1905 might override this decision by tsx=on the command line parameter.
1910 This option allows to set the default tsx mode between tsx=on, =off
1915 platforms or on if TSX is in use and the security aspect of tsx is not
1921 TSX is disabled if possible - equals to tsx=off command line parameter.
1926 TSX is always enabled on TSX capable HW - equals the tsx=on command
1933 side channel attacks- equals the tsx=auto command line parameter.
