Commit Message

Todd Brandt May 14, 2019, 5:53 p.m. UTC
bootgraph:
- dmesg log format has changed, update parser in two places
- fix prints in preparation for upgrade to python3

sleepgraph:
- fix prints in preparation for upgrade to python3
- add new trace events and kprobes to cover freeze more completely
- add new -ftop callgraph trace over suspend_devices_and_enter
- add -wifi option to check if a wifi connection is active
- add -skipkprobe option to suppress unwanted kprobes in dev mode
- add kernel params and sysinfo to the log output
- don't crash if /dev/mem is throwing IO errors, ignore FPDT and DMI
- fix kprobe length calculation when calls are recursive
- add several new kernel issue definitions for USB, ACPI, ATA, etc
- enable turbostat output to be read from stdout instead of from file
- add BIOS call data to the timeline from acpi_ps_execute_method kprobe
