Subject: [PATCH 00/46] perf tools: Fix and improvements (bpf and overwrite)
Date: Fri, 26 Feb 2016 09:31:48 +0000 [thread overview]
Message-ID: <1456479154-136027-1-git-send-email-wangnan0@huawei.com> (raw)
Hi Arnaldo,
The following changes since commit bb109acc4adeae425147ca87b84d312ea40f24f1:
perf tools: Fix parsing of pmu events with empty list of modifiers (2016-02-25 10:56:21 -0300)

perf tools: Don't warn about out of order event if write_backward is used (2016-02-26 09:11:20 +0000)
----------------------------------------------------------------
- BPF related: 'perf trace' support bpf-output event
- perf overwrite support: Code improvements based on Jiri's suggestion
Signed-off-by: Wang Nan <wangnan0@huawei.com>
----------------------------------------------------------------
Wang Nan (46):

perf record: Split output into multiple files via '--switch-output'
perf record: Force enable --timestamp-filename when --switch-output is provided
perf record: Disable buildid cache options by default in switch output mode
perf record: Re-synthesize tracking events after output switching
perf record: Generate tracking events for process forked by perf
perf record: Ensure return non-zero rc when mmap fail
perf record: Prevent reading invalid data in record__mmap_read
perf tools: Add evlist channel helpers

perf tools: Add API to pause a channel
perf record: Toggle overwrite ring buffer for reading
perf record: Rename variable to make code clear
perf record: Read from backward ring buffer
perf record: Allow generate tracking events at the end of output
