Bharat Bhushan 78accda4f8 KVM: PPC: Added one_reg interface for timer registers ... If userspace wants to change some specific bits of TSR (timer status register) then it uses GET/SET_SREGS ioctl interface. So the steps will be: i) user-space will make get ioctl, ii) change TSR in userspace iii) then make set ioctl. It can happen that TSR gets changed by kernel after step i) and before step iii). To avoid this we have added below one_reg ioctls for oring and clearing specific bits in TSR. This patch adds one registerface for: 1) setting specific bit in TSR (timer status register) 2) clearing specific bit in TSR (timer status register) 3) setting/getting the TCR register. There are cases where we want to only change TCR and not TSR. Although we can uses SREGS without KVM_SREGS_E_UPDATE_TSR flag but I think one reg is better. I am open if someone feels we should use SREGS only here. 4) getting/setting TSR register Signed-off-by: Bharat Bhushan <bharat.bhushan@freescale.com> Signed-off-by: Alexander Graf <agraf@suse.de>		2013-03-22 01:21:06 +01:00
