Currently the cyclictest runs only 1 seconds, that's too short for patch verification. Increase this time to be 10 minutes to make it more reasonable. In long term, we should have another type of task to run 24 hours testing. Change-Id: I48534b3da48018060c885305488b969286c8bd49 Signed-off-by: Yunhong Jiang <yunhong.jiang@linux.intel.com>

The scripts will be triggered to build kernel-rpm & qemu-rpm packages inside centos docker, and kernel-debian & qemu-debian packages inside ubuntu docker, as part of the CICD process. After the new builds are ready, they will be deployed on the pharos testbed for verification. Later, these will be consumed/triggered by verify/daily Releng JJBs.

2016-07-21Add the "timers: do not raise softirq unconditionally" temporarilyYunhong Jiang2-8/+29
This patch enable the nohz_full and is important for RT. Bring it back temporarily, while waiting for more work on RT community. Please refer to https://lkml.org/lkml/2015/3/17/783 for more information of the revert. A little rebase needed because it's reverted on old code base. Please notice that we change the rt_mutex_trylock() so that we can get the tvec_base lock there. This is sure to be wrong, and should be fixed cleanly. And that's the major reason the original patch are reverted on the upstream RT linux. Will discuss with upstream on how to achieve the solution.

2016-07-18KVM: nVMX: keep preemption timer enabled during L2 executionPaolo Bonzini1-2/+13
Because the vmcs12 preemption timer is emulated through a separate hrtimer, we can keep on using the preemption timer in the vmcs02 to emulare L1's TSC deadline timer. However, the corresponding bit in the pin-based execution control field must be kept consistent between vmcs01 and vmcs02. On vmentry we copy it into the vmcs02; on vmexit the preemption timer must be disabled in the vmcs01 if a preemption timer vmexit happened while in guest mode. The preemption timer value in the vmcs02 is set by vmx_vcpu_run, so it need not be considered in prepare_vmcs02.

2016-07-18KVM: nVMX: avoid incorrect preemption timer vmexit in nested guestWanpeng Li1-0/+2
The preemption timer for nested VMX is emulated by hrtimer which is started on L2 entry, stopped on L2 exit and evaluated via the check_nested_events hook. However, nested_vmx_exit_handled is always returning true for preemption timer vmexit. Then, the L1 preemption timer vmexit is captured and be treated as a L2 preemption timer vmexit, causing NULL pointer dereferences or worse in the L1 guest's vmexit handler: BUG: unable to handle kernel NULL pointer dereference at (null) IP: [< (null)>] (null) PGD 0 Oops: 0010 [#1] SMP Call Trace: ? kvm_lapic_expired_hv_timer+0x47/0x90 [kvm] handle_preemption_timer+0xe/0x20 [kvm_intel] vmx_handle_exit+0x169/0x15a0 [kvm_intel] ? kvm_arch_vcpu_ioctl_run+0xd5d/0x19d0 [kvm] kvm_arch_vcpu_ioctl_run+0xdee/0x19d0 [kvm] ? kvm_arch_vcpu_ioctl_run+0xd5d/0x19d0 [kvm] ? vcpu_load+0x1c/0x60 [kvm] ? kvm_arch_vcpu_load+0x57/0x260 [kvm] kvm_vcpu_ioctl+0x2d3/0x7c0 [kvm] do_vfs_ioctl+0x96/0x6a0 ? __fget_light+0x2a/0x90 SyS_ioctl+0x79/0x90 do_syscall_64+0x68/0x180 entry_SYSCALL64_slow_path+0x25/0x25 Code: Bad RIP value.

If fail to program hardware preemption timer, we will fallback to hrtimer based method, however, a previous programmed preemption timer miss to cancel in this scenario which results in one hardware preemption timer and one hrtimer emulated tsc deadline timer run simultaneously. So sometimes the target guest deadline tsc is earlier than guest tsc, which leads to the computation in vmx_set_hv_timer can underflow and cause delta_tsc to be set a huge value, then host soft lockup as above. This patch fix it by cancelling the previous programmed preemption timer if there is once we failed to program the new preemption timer and fallback to hrtimer based method.

If the TSC deadline timer is programmed really close to the deadline or even in the past, the computation in vmx_set_hv_timer can underflow and cause delta_tsc to be set to a huge value. This generally results in vmx_set_hv_timer returning -ERANGE, but we can fix it by limiting delta_tsc to be positive or zero.
