This adds a new CPU model named "Broadwell". It has all the features
|
|
|
958e1b |
from Haswell, plus PREFETCHW, RDSEED, ADX, SMAP.
|
|
|
958e1b |
|
|
|
958e1b |
PREFETCHW was already supported as "3dnowprefetch".
|
|
|
958e1b |
[Already supported by RHEL-7 kernel, too]
|
|
|
958e1b |
|
|
|
958e1b |
RDSEED, ADX was added on Linux v3.15-rc1.
|
|
|
958e1b |
[RDSEED: RHEL-7 kernel commit c4311bc8c9167a3d7011aff8728fd8067404246f]

[ADX: RHEL-7 kernel commit fe5f6cdf4428dcd01f5b060b31eabe44c2f5e468]
|
|
|
958e1b |
|
|
|
958e1b |
SMAP was added on Linux v3.15-rc2.
|
|
|
958e1b |
[RHEL-7 kernel commit 890edaefc84a2596a3f17d1e9967935a1984e302]

About migration support:
|
|
|
958e1b |
* SMAP state is a single bit on CR4 which is already migrated;
|
|
|
958e1b |
* PREFETCHW, RDSEED, ADX have no new state.
