That reduces the emulation quality as vcpu->arch.switch_db_regs is only
set if some breakpoint is active while dr6 has its use also when that is
not the case).
True - there's the TF reason reporting bits.
How about this then:
- if !switch_db_regs, trap #DB
- on #DB trap, copy DR6.BS and DR6.BT to vcpu->arch.dr6, and reinject
the #DB
?
