[Qemu-devel] [PATCH v2 00/34] kvm_stat: Cleanup and fixup

[Janosch Frank]

Kvm_stat is a very helpful script for checking the state of VMs, but
when I tried to introduce new features it broke every few lines.

This patch series aims to make the script more readable and durable,
so future additions to it will break it less likely. It also fixes
input/output problems for all of its interface modes.

Testing was done rarely on X86_64 RHEL 6.7 and mostly on s390. Tests
on other architectures would be beneficial.

Changes in v2:
Dropped scripts/kvm/kvm_stat: Move to argparse and add description
Added scripts/kvm/kvm_stat: Add optparse description

Exchanged PATH_DEBUGFS with PATH_DEBUGFS_KVM
Exchanged PATH_TRACING with PATH_DEBUGFS_TRACING
Exchanged os.os with os

Split up get_online_cpu.
Now using standard parameters to pass data to an Event object.
Grouped arch specific data in Arch subclasses.
Implemented curse wrapping through magic enter/exit in the Tui class.
