Hi Duc Anh, I assume you want to enable SMT for X86. SMT for X86 has yet to be supported, but there is progress on this recently. You can keep track of the development via JIRA ticket (https://gem5.atlassian.net/browse/GEM5-332) and via this relation change (https://gem5-review.googlesource.com/c/public/gem5/+/35837).
Regarding the stats error, can you be a little bit more specific about the version of gem5 that you're using and the command that you used? Are they the same as the ones in the first email (https://www.mail-archive.com/gem5-users@gem5.org/msg18678.html)?
