| |
Some updates coming with 5.6 rc:
Change in API of bootconfig (before it comes live in a release) - Have a magic value "BOOTCONFIG" in initrd to know a bootconfig exists - Set CONFIG_BOOT_CONFIG to 'n' by default - Show error if "bootconfig" on cmdline but not compiled in - Prevent redefining the same value - Have a way to append values
Synthetic event fixes: - Switch to raw_smp_processor_id() for recording CPU value in preempt section. (No care for what the value actually is) - Fix samples always recording u64 values - Fix endianess - Check number of values matches number of fields - Fix a printing bug
Fix of trace_printk() breaking postponed start up tests
Make a function static that is only used in a single file.
Masami Hiramatsu (8): tracing: Clear trace_state when starting trace bootconfig: Set CONFIG_BOOT_CONFIG=n by default bootconfig: Add bootconfig magic word for indicating bootconfig explicitly tools/bootconfig: Remove unneeded error message silencer bootconfig: Reject subkey and value on same parent key bootconfig: Print array as multiple commands for legacy command line bootconfig: Prohibit re-defining value on same key bootconfig: Add append value operator support
Qiujun Huang (1): bootconfig: Mark boot_config_checksum() static
Steven Rostedt (VMware) (2): tracing: Have synthetic event test use raw_smp_processor_id() tracing: Disable trace_printk() on post poned tests
Tom Zanussi (4): tracing: Make sure synth_event_trace() example always uses u64 tracing: Make synth_event trace functions endian-correct tracing: Check that number of vals matches number of synth event fields tracing: Fix number printing bug in print_synth_event()
