HV: Added Initial support for SEP/SOCWATCH profiling This patch adds support to sep/socwatch profiling Adds 2 new files include/arch/x86/profiling.h and arch/x86/profiling.c which contains most of the implementation for profiling,most of the functions in profiling.c have dummy implementation and will be implemented in next patches a. cpu.c, Initial profiling setup is done as part of bsp_boot_post and cpu_secondary_post flow b. vmcall.c, New ioctl is added for performing profiling related operations in vmcall_vmexit_handler ioctl - HC_PROFILING_OPS function - hcall_profiling_ops() c. common/hypercall.c, hcall_profiling_ops() implementation. d. hv_main.c, In vcpu_thread calling profiling related functions to save vm context e. acrn_hv_defs.h, list all the profiling command types Tracked-On: projectacrn#1409 Acked-by: Eddie Dong <eddie.dong@intel.com> Signed-off-by: Chinthapally, Manisha <manisha.chinthapally@intel.com>

HV:treewide:rename vcpu data structure For data structure types "struct vcpu", its name is identical with variable name in the same scope. This is a MISRA C violation. Naming convention rule:If the data structure type is used by multi modules, its corresponding logic resource is exposed to external components (such as SOS, UOS), and its name meaning is simplistic (such as vcpu, vm), its name needs prefix "acrn_". The following udpates are made: struct vcpu *vcpu-->struct acrn_vcpu *vcpu Tracked-On: #861 Signed-off-by: Xiangyang Wu <xiangyang.wu@linux.intel.com>

void profiling_vmenter_handler(struct acrn_vcpu *vcpu);
profiling: split profiling_vmexit_handler into two functions This patch fixes incorrect vm_id captured when sampling PMU data. Currently, the vm_id gets attributed to ACRN hypervisor, rather than actual guest vm_id. The issue is identified that the existing code captures the guest vm info after vmexit_hander function is completed, in which the profiling module points its context to VMM. When the vmexit happens by PMI, the guest context should be captured so that the attribution to proper guest vm can happen. This change will also allow to capture more accurate TSC when vmexit happens. Tracked-On: #2043 Signed-off-by: Min Lim <min.yeol.lim@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>
