From c207a34872be923887feb834fb3971213bfe61d4 Mon Sep 17 00:00:00 2001 From: Sebastian Goscik Date: Thu, 2 Jun 2016 15:14:03 +0100 Subject: [PATCH] cpustates: Now shows a warning when it fails to nudge a core. Before WA would raise a error message that wasn't very clear. Now when cpustates tries to nudge cores and and error occurs it will only show a warning (which promts users to check if the cpu is hot plugged out) and keep going with the reset of the run without causing errors in other WA extensions. --- wlauto/result_processors/cpustate.py | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/wlauto/result_processors/cpustate.py b/wlauto/result_processors/cpustate.py index 5bf20f44..7bc6847b 100755 --- a/wlauto/result_processors/cpustate.py +++ b/wlauto/result_processors/cpustate.py @@ -19,7 +19,7 @@ from collections import OrderedDict from wlauto import ResultProcessor, Parameter from wlauto.core import signal -from wlauto.exceptions import ConfigError +from wlauto.exceptions import ConfigError, DeviceError from wlauto.instrumentation import instrument_is_installed from wlauto.utils.power import report_power_stats from wlauto.utils.misc import unique @@ -169,7 +169,10 @@ class CpuStatesProcessor(ResultProcessor): self.logger.debug('Nudging all cores awake...') for i in xrange(len(device.core_names)): command = device.busybox + ' taskset 0x{:x} {}' - device.execute(command.format(1 << i, 'ls')) + try: + device.execute(command.format(1 << i, 'ls')) + except DeviceError: + self.logger.warning("Failed to nudge CPU %s, has it been hot plugged out?", i) def process_iteration_result(self, result, context): trace = context.get_artifact('txttrace')
