From 49218edd649ae4922aa776aad5b7a65d028c6e96 Mon Sep 17 00:00:00 2001 From: Todd E Brandt Date: Wed, 5 Jul 2017 14:42:55 -0700 Subject: pm-graph: AnalyzeSuspend v4.7 - changed -rtcwake parameter to be on & 15 sec by default, to disable rtcwake use: "-rtcwake off" - changed behavior of -o: renames HTML file on rerun, subdir on new run - changed execution_misalignment error to missing_function_name - add sysinfo to logs and timeline via a custom dmidecode call it supplants dmidecode tool when used as a library call - add -sysinfo command, displays dmidecode values and cpu/mem info - set trace buffer size to lesser of memtotal/2 or 2GB when using callgraph - add support for /sys/power/mem_sleep. if mem_sleep found: mem-shallow=standby, mem-s2idle=freeze, mem-deep=mem - remove redundant javascript - cosmetic changes to HTML layout Signed-off-by: Todd Brandt Signed-off-by: Rafael J.
