Hi,
Based on discussions in:

About KVM_SET_GSI_ROUTING ioctl, I tested changing RCU to SRCU, but
unfortunately
it looks like SRCU's grace period is no better than RCU. I haven't got any idea
why this, but I suppose the te

Hi all,
XEN supported last branch recording(LBR) since 2007.
And KVM has supported vPMU, but hasn't support LBR for intel CPUs yet.
May I ask why? Is there any considerations to implement it? Thanks.
PS: I tried to google some reasons about this, but I got nothing. :(
Regards,
-Gonglei
