* Tracing: Fix simpletrace.py error on tcg enabled binary tracesChristoph Seifert2014-11-181-34/+33
| | | | | | | simpletrace.py does not recognize the tcg option while reading trace-events file. In result simpletrace does not work on binary traces and tcg enabled events. Moved transformation of tcg enabled events to _read_events() which is used by simpletrace.

| | | | | | | | | | | | | | | | | | Unfortunately ioctl numbers are platform specific, so abstract them out of the code so they can be overridden.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The current platform detection is a little bit messy. We look for lines in /proc/cpuinfo starting with 'flags' OR 'vendor-id', and scan both for values we know will only occur in one or the other. We also keep scanning once we've found a value, which could be a feature, but isn't in this case. We'd also like to add another platform, powerpc, which will just make it worse.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | In kvm_stat we have a dictionary of exit reasons for s390. Firstly these are not s390 specific, they are the generic exit reasons. So rename the dictionary to reflect that, and add it separately to filters[]. Secondly, the values are defined using hex, but in the kernel header they are decimal. That means values above 9 in kvm_stat are incorrect. While we're there, fix the whitespace to match the rest of the file.

|/ | | | | | | | | | | | | In kvm_stat we grovel through /sys to find out how many cpus are in the system. However if a cpu is offline it will still be present in /sys, and the perf_event_open() will fail. Modify the logic to only return online cpus. We need to be careful on systems which don't support cpu hotplug, the online file will not be present at all.

| * qapi: add visit_start_union and visit_end_unionMichael Roth2014-09-261-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases an input visitor might bail out on filling out a struct for various reasons, such as missing fields when running in strict mode. In the case of a QAPI Union type, this may lead to cases where the .kind field which encodes the union type is uninitialized. Subsequently, other visitors, such as the dealloc visitor, may use this .kind value as if it were initialized, leading to assumptions about the union type which in this case may lead to segfaults. For example, freeing an integer value. However, we can generally rely on the fact that the always-present .data void * field that we generate for these union types will always be NULL in cases where .kind is uninitialized (at least, there shouldn't be a reason where we'd do this purposefully). So pass this information on to Visitor implementation via these optional start_union/end_union interfaces so this information can be used to guard against the situation above. We will make use of this information in a subsequent patch for the dealloc visitor.

It flags various errors, like version mismatch, sections going away, size mismatches, etc. This script is tolerant of a few changes that do not change the on-wire format, like embedding a few fields within substructs. The script takes -s/--src and -d/--dest parameters, to which filenames are given as arguments. Example: (in a qemu 2.0 tree): ./x86_64-softmmu/qemu-system-x86_64 -dump-vmstate qemu-2.0.json (in a qemu 2.2 tree:) ./x86_64-softmmu/qemu-system-x86_64 -dump-vmstate -M pc-i440fx-2.0 \ qemu-2.2-m2.0.json ./scripts/vmstate-static-checker.py -s qemu-2.0.json -d qemu-2.2-m2.0.json The script also takes a --reverse parameter to switch the src and dest jsons. This is just a shorthand for reversing the src and dest. The --help parameter shows usage information.

* | qapi script: add event supportWenchao Xia2014-06-232-0/+381
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qapi-event.py will parse the schema and generate qapi-event.c, then the API in qapi-event.c can be used to handle events in qemu code. All API have prefix "qapi_event". The script mainly includes two parts: generate API for each event define, generate an enum type for all defined events. Since in some cases the real emit behavior may change, for example, qemu-img would not send a event, a callback layer is used to control the behavior. As a result, the stubs at compile time can be saved, the binding of block layer code and monitor code will become looser.

* trace: Multi-backend tracingLluís Vilanova2014-06-093-41/+41
| | | | | | | | | | | | | | | Adds support to compile QEMU with multiple tracing backends at the same time. For example, you can compile QEMU with: $ ./configure --enable-trace-backends=ftrace,dtrace Where 'ftrace' can be handy for having an in-flight record of events, and 'dtrace' can be later used to extract more information from the system. This patch allows having both available without recompiling QEMU. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
