Merge tag 'trace-tools-v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing tools updates from Steven Rostedt: - Add ':' to getopt option 'trace-buffer-size' in timerlat_hist for consistency - Remove unused sched_getattr define - Rename sched_setattr() helper to syscall_sched_setattr() to avoid conflicts - Update counters to long from int to avoid overflow - Add libcpupower dependency detection - Add --deepest-idle-state to timerlat to limit deep idle sleeps - Other minor clean ups and documentation changes * tag 'trace-tools-v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: verification/dot2: Improve dot parser robustness tools/rtla: Improve exception handling in timerlat_load.py tools/rtla: Enhance argument parsing in timerlat_load.py tools/rtla: Improve code readability in timerlat_load.py rtla/timerlat: Do not set params->user_workload with -U rtla: Documentation: Mention --deepest-idle-state rtla/timerlat: Add --deepest-idle-state for hist rtla/timerlat: Add --deepest-idle-state for top rtla/utils: Add idle state disabling via libcpupower rtla: Add optional dependency on libcpupower tools/build: Add libcpupower dependency detection rtla/timerlat: Make timerlat_hist_cpu->*_count unsigned long long rtla/timerlat: Make timerlat_top_cpu->*_count unsigned long long tools/rtla: fix collision with glibc sched_attr/sched_set_attr tools/rtla: drop __NR_sched_getattr rtla: Fix consistency in getopt_long for timerlat_hist rv: Fix a typo tools/rv: Correct the grammatical errors in the comments tools/rv: Correct the grammatical errors in the comments rtla: use the definition for stdout fd when calling isatty()
