Subject: [bpf-next 0/3] Using log2 histogram to display the statistics of every softirq execution
Date: Sun, 20 Sep 2020 22:45:44 +0800 [thread overview]
Message-ID: <20200920144547.56771-1-xhao@linux.alibaba.com> (raw)
The purpose of this series of patches is to provide a way of log2
histogram to display in sample/bpf dir, you can refer to the
patch three to use it.
Xin Hao (3):
sample/bpf: Avoid repetitive definition of log2 func
sample/bpf: Add log2 histogram function support
samples/bpf: Add soft irq execution time statistics
