Subject: [for-linus][PATCH 00/15] tracing: Updates coming for 5.6 rc release
Date: Mon, 24 Feb 2020 12:20:22 -0500 [thread overview]
Message-ID: <20200224172022.330525468@goodmis.org> (raw)
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()
