For example, the platform may include a dedicated interrupt controller used specifically for handling system wakeup events. Then, if a given interrupt line is supposed to -wake up the system from sleep sates, the corresponding input of that interrupt +wake up the system from sleep states, the corresponding input of that interrupt controller needs to be enabled to receive signals from the line in question. After wakeup, it generally is better to disable that input to prevent the dedicated controller from triggering interrupts unnecessarily. diff --git a/tools/power/pm-graph/sleepgraph.py b/tools/power/pm-graph/sleepgraph.py index c60c90f35d18..82c09cd25cc2 100755 --- a/tools/power/pm-graph/sleepgraph.py +++ b/tools/power/pm-graph/sleepgraph.py @@ -120,9 +120,9 @@ class SystemValues: cgexp = False testdir = '' outdir = '' - tpath = '/sys/kernel/debug/tracing/' + tpath = '/sys/kernel/tracing/' fpdtpath = '/sys/firmware/acpi/tables/FPDT' - epath = '/sys/kernel/debug/tracing/events/power/' + epath = '/sys/kernel/tracing/events/power/' pmdpath = '/sys/power/pm_debug_messages' s0ixpath = '/sys/module/intel_pmc_core/parameters/warn_on_s0ix_failures' s0ixres = '/sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us' diff --git a/tools/power/x86/amd_pstate_tracer/amd_pstate_trace.py b/tools/power/x86/amd_pstate_tracer/amd_pstate_trace.py index 2dea4032ac56..904df0ea0a1e 100755 --- a/tools/power/x86/amd_pstate_tracer/amd_pstate_trace.py +++ b/tools/power/x86/amd_pstate_tracer/amd_pstate_trace.py @@ -248,7 +248,7 @@ def signal_handler(signal, frame): ipt.free_trace_buffer() sys.exit(0) -trace_file = "/sys/kernel/debug/tracing/events/amd_cpu/enable" +trace_file = "/sys/kernel/tracing/events/amd_cpu/enable" signal.signal(signal.SIGINT, signal_handler) interval = "" @@ -319,7 +319,7 @@ print(cur_version) cleanup_data_files() if interval: - file_name = "/sys/kernel/debug/tracing/trace" + file_name = "/sys/kernel/tracing/trace" ipt.clear_trace_file() ipt.set_trace_buffer_size(memory) ipt.enable_trace(trace_file) diff --git a/tools/power/x86/intel_pstate_tracer/intel_pstate_tracer.py b/tools/power/x86/intel_pstate_tracer/intel_pstate_tracer.py index b46e9eb8f5aa..ec3323100e1a 100755 --- a/tools/power/x86/intel_pstate_tracer/intel_pstate_tracer.py +++ b/tools/power/x86/intel_pstate_tracer/intel_pstate_tracer.py @@ -373,7 +373,7 @@ def clear_trace_file(): """ Clear trace file """ try: - f_handle = open('/sys/kernel/debug/tracing/trace', 'w') + f_handle = open('/sys/kernel/tracing/trace', 'w') f_handle.close() except: print('IO error clearing trace file ') @@ -401,7 +401,7 @@ def set_trace_buffer_size(memory): """ Set trace buffer size """ try: - with open('/sys/kernel/debug/tracing/buffer_size_kb', 'w') as fp: + with open('/sys/kernel/tracing/buffer_size_kb', 'w') as fp: fp.write(memory) except: print('IO error setting trace buffer size ') @@ -411,7 +411,7 @@ def free_trace_buffer(): """ Free the trace buffer memory """ try: - open('/sys/kernel/debug/tracing/buffer_size_kb' + open('/sys/kernel/tracing/buffer_size_kb' , 'w').write("1") except: print('IO error freeing trace buffer ') @@ -495,7 +495,7 @@ def signal_handler(signal, frame): sys.exit(0) if __name__ == "__main__": - trace_file = "/sys/kernel/debug/tracing/events/power/pstate_sample/enable" + trace_file = "/sys/kernel/tracing/events/power/pstate_sample/enable" signal.signal(signal.SIGINT, signal_handler) interval = "" @@ -569,7 +569,7 @@ if __name__ == "__main__": cleanup_data_files() if interval: - filename = "/sys/kernel/debug/tracing/trace" + filename = "/sys/kernel/tracing/trace" clear_trace_file() set_trace_buffer_size(memory) enable_trace(trace_file) |
