Gonglei	81b07353c5	Remove superfluous '\n' around error_report() Signed-off-by: Gonglei <arei.gonglei@huawei.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>	11 years ago
Lluís Vilanova	14101d028d	trace: [hmp] Reimplement "trace-event" and "info trace-events" using QMP Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu> Message-id: 20140825112002.31112.60143.stgit@fimbulvetr.bsc.es Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>	12 years ago
Alexey Kardashevskiy	a35d9be622	trace: Replace fprintf with error_report and print location This replaces fprintf(stderr) with error_report. This moves local variables to the beginning of the function to comply with QEMU's coding style.

Lluís Vilanova	5b808275f3	trace: Multi-backend tracing 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>	12 years ago
Alexey Kardashevskiy	82432638eb	trace: Replace error with warning if event is not defined At the moment QEMU exits if trace point is not defined which makes a developer life harder if he has to switch between branches with different traces implemented. This replaces error+exit wit WARNING if the tracepoint does not exist or not traceable. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>	12 years ago
Lluís Vilanova	b1bae816c4	trace: Provide a detailed event control interface This interface decouples event obtaining from interaction. Events can be obtained through three different methods: * identifier * name * simple wildcard pattern Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>	13 years ago
Gerd Hoffmann	ddde8acc98	trace: allow disabling events in events file Disable trace events prefixed with a '-'. Useful to enable a group of tracepoints with exceptions, like this: usb_xhci_port_* -usb_xhci_port_read which will enable all xhci port tracepoints except reads. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>	14 years ago
Alexey Kardashevskiy	794b1f962e	trace: added ability to comment out events in the list It is convenient for debug to be able to switch on/off some events easily. The only possibility now is to remove event name from the file completely and type it again when we want it back. The patch adds '#' symbol handling as a comment specifier.

Lluís	23d15e860b	trace: add "-trace events" argument to control initial state The "-trace events" argument can be used to provide a file with a list of trace event names that will be enabled prior to starting execution, thus providing early tracing. This saves the user from manually toggling event states through the monitor interface or whichever backend-specific interface. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu>	15 years ago
