| | * x86: extended "flags" to show virtualization HW feature in /proc/cpuinfoSheng Yang2008-09-101-0/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hardware virtualization technology evolves very fast. But currently it's hard to tell if your CPU support a certain kind of HW technology without digging into the source code. The patch add a new catagory in "flags" under /proc/cpuinfo. Now "flags" can indicate the (important) HW virtulization features the CPU supported as well. Current implementation just cover Intel VMX side.
