Subject: [PATCH] target/i386: Add Snowridge-v2 (no MPX) CPU model
|
||
|
|
|
||
|
|
Add new version of Snowridge CPU model that removes MPX feature.
|
||
|
|
|
||
|
|
MPX support is being phased out by Intel. GCC has dropped it, Linux kernel
|
||
|
|
and KVM are also going to do that in the future.
