2016-02-09scripts/kvm/kvm_stat: Fix tracefs access checkingJanosch Frank1-6/+17
On kernels build without CONFIG_TRACING kvm_stat will bail out even when traces are not used. This is not very helpful, especially if the user can't install a new kernel. Instead, we should warn the user and fall back to debugfs statistics. These changes check if trace statistics were selected without kernel support, warn with a small timeout, set the debugfs statistics option to True and the tracefs one to False.

Interactively changing the filter is much more useful than the drilldown, because it is more versatile.

2016-01-26scripts/kvm/kvm_stat: Fixup filteringJanosch Frank1-11/+21
When filtering, the group leader event should not be disabled, as all other events under it will also be disabled. Also we should make sure that values from disabled fields will not be displayed. This also filters the fields from the log and batch output for better readability. Also the drilldown update now directly checks for the stats' field filter and (un)sets drilldown accordingly.

2016-01-26scripts/kvm/kvm_stat: Fix rlimit for unprivileged usersJanosch Frank1-3/+11
Setting the hard limit as a unprivileged user either returns an error when it is higher than the current one or irreversibly sets it lower. Therefore we leave the hardlimit untouched as long as we don't need to raise it as this needs CAP_SYS_RESOURCE. This gives admins the possibility to run the script as an unprivileged user to increase security.

All initializations of the ctypes struct that don't need additional information were moved to its init method.

Additionaly the detect_platform routine which prepares the data that goes into the variable was called on each start of the script, no matter if the class was needed.

s390 machines can also be detected via uname -m, i.e. python's os.uname, no need for more complicated checks. Calling uname once and saving its value for multiple checks is perfectly sufficient.

2015-01-26kvm_stat: Add RESET support for perf event ioctlWei Huang1-0/+5
While running kvm_stat using tracepoint on ARM64 hardware (e.g. "kvm_stat -1 -t"), the initial values of some kvm_userspace_exit counters were found to be very suspecious. For instance the tracing tool showed that S390_TSCH was called many times on ARM64 machine, which apparently was wrong. This patch adds RESET ioctl support for perf monitoring. Before calling ioctl to enable a perf event, this patch resets the counter first. With this patch, the init counter values become correct on ARM64 hardware. Example: ==== before patch ==== kvm_userspace_exit(S390_SIEIC) 1426 0 kvm_userspace_exit(S390_TSCH) 339 0 ==== after patch ==== kvm_userspace_exit(S390_SIEIC) 0 0 kvm_userspace_exit(S390_TSCH) 0 0 Signed-off-by: Wei Huang <wei@redhat.com>

2014-10-31kvm_stat: Abstract ioctl numbersMichael Ellerman1-3/+9
Unfortunately ioctl numbers are platform specific, so abstract them out of the code so they can be overridden. As it happens x86 and s390 share the same values, so nothing needs to change yet. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
