But Why?
IBS_CAPS_BRNTRGT and IBS_CAPS_OPDATA4 indicate support for the respective
MSRs
Ok, I was just making sure.
Btw, MSR_AMD64_IBS_FETCH_EXTD_CTL seems unused. Forgotten?
No, There aren't any bits in MSR_AMD64_IBS_FETCH_EXTD_CTL that we need
to configure right now.
So, have included it here mainly to keep the MSR listing consistent with
the manual.
Thanks,
