Description
This pull request introduces new eBPF helper functions for retrieving time since boot in milliseconds and updates the codebase to use a new timing function,
cxplat_query_time_since_boot_precise. Additionally, it includes updates to related data structures and test cases.New eBPF Helper Functions:
bpf_ktime_get_boot_msandbpf_ktime_get_mshelper functions to retrieve time since boot in milliseconds, including and excluding suspended time, respectively. (include/bpf_helper_defs.h,include/ebpf_structs.h,libs/execution_context/ebpf_core.c,libs/execution_context/ebpf_general_helpers.c) [1] [2] [3] [4]Codebase Updates:
ebpf_query_time_since_boot_preciseandebpf_query_time_since_boot_approximatewithcxplat_query_time_since_boot_preciseandcxplat_query_time_since_boot_approximateacross various files for better performance and consistency.
