ACRN hypervisor needs to kick vCPU off VMX non-root mode to do some operations in hypervisor, such as interrupt/exception injection, EPT flush etc. For non lapic-pt vCPUs, we can use IPI to do so. But

Will drop this patch when PR.

This patch adds one new option '-a' to specify the cpus where we should capture the trace data. If the this option is not set or set with wrong optarg, we will capture the trace data of all possible c

Different board gets different frequncy. The correct frequency is essential for correct result. So, this patch make it mandatory instead of optional with a default value. Signed-off-by: Kaige Fu <kaig

It is better to output it using float instead of int. Otherwise, we will get '0 sec' for total run time if it is less than one second. Signed-off-by: Kaige Fu <kaige.fu@...> --- misc/tools/acrnt

The key in the list is unique. So, it is better to break the loop when find the matching key instead of traversing the whole list. Signed-off-by: Kaige Fu <kaige.fu@...> --- misc/tools/acrntrace

Originally, we assume that the vmenter will sit at the first line of the trace file. But if the vmexit comes earlier than vmenter. The total vmexit cnt will be set as 0 by the first vmenter. This patc

This patchset mainly for: - Fix the total vmexit cnt and total run time issue. - Make the -f/--frequency mandatory to get correct result. - Add opt to specify the cpus where we should capture the data

hypcall_id has a type of uint64_t and should use 'llx' as formatting flag instead of '%d'. Otherwise, we will get a confusing error log when not-allowed hypercall occurs. Without this patch: [96707209

Hi Fengwei,

Hi Fengwei,

We should use INIT signal to notify the vcpu threads when powering off the hard RTVM. To achive this, we should set the vcpu->thread_obj.notify_mode as SCHED_NOTIFY_INIT. Patch (27163df9 hv: sched: ad

Hi Fuzhong,

This patch adds the following kernel params to gain a more deterministic results of preempt-rt linux. clocksource=tsc processor.max_cstate=0 intel_idle.max_cstate=0 intel_pstate=disabled mce=ignore_ce

Thanks.

Hi Eddie,

Hi Eddie,

The policy of vART is that software in native can run in VM too. And in native side, the relationship between the ART hardware and TSC is: pTSC = (pART * M) / N + pAdjust The vART solution is: - Prese
