Subject: [PATCH v2 00/14] perf kvm: Support histograms and TUI mode
Date: Tue, 28 Feb 2023 16:41:33 +0800 [thread overview]
Message-ID: <20230228084147.106167-1-leo.yan@linaro.org> (raw)
This patch set is to enable histograms and (partially) TUI mode in perf
kvm tool.
Patch set v1 [1] gives brief introduction for the change and this series
has a minor update for the patch 13 'perf kvm: Add TUI mode for stat
report' to avoid building failure when the system doesn't support
HAVE_SLANG_SUPPORT.
We can use below commands for testing this series:
In a terminal, you could launch a virtual machine with qemu command; in
below case, I downloaded a Ubuntu (or Debian) iso file and used it as
the file system image:
$ qemu-system-x86_64 -M pc -enable-kvm -cpu host -m 4096 -hda ubuntu-22.04-desktop-amd64.iso
Then in another terminal, I can use below command to capture KVM trace
data and report the result:
# cd linux/tools/perf
# ./perf kvm stat record
# ./perf kvm stat report => Output in TUI mode
# ./perf kvm stat report --stdio => Output in stdio mode
Changes from v1:
* Updated the patch 13 'perf kvm: Add TUI mode for stat report' to avoid
building failure if no support HAVE_SLANG_SUPPORT.
