[PATCH v6 11/60] i386/tdx: Make sept_ve_disable set by default
Posted by Xiaoyao Li 2 weeks, 4 days ago
From: Isaku Yamahata <isaku.yamahata@intel.com>

For TDX KVM use case, Linux guest is the most major one.  It requires
sept_ve_disable set.  Make it default for the main use case.  For other use
case, it can be enabled/disabled via qemu command line.
