LDTSTOP may need to SB to help.
When trying to change cpu fid, CPU need
LDTSTOP to make the FID change effective. enable_fid_change_on_sb will
enable ldtstop on sb.
Current Amd8111 support code already have
enable_fid_change_on_sb in the public tree.
Serverworks ht1000 need to call ldtstop explicitly
to make fid change effective. I will check in the code after the new cpu is
released.
The problem the ck804 has problem with
ldtstop. We have to use some other way to make it effective…
