Options allow for changes in commands behavior. This commit introduces the QCO_NO_SUCCESS_RESP option, which causes a command to not emit a success response. This is needed by commands such as qemu-ga's guest-shutdown, which may not be able to complete before the VM vanishes. In this case, it's useful and simpler not to bother sending a success response.

2012-04-18tracetool: handle DTrace keywords 'in', 'next', 'self'Stefan Hajnoczi1-4/+4
Language keywords cannot be used as argument names. The DTrace backend appends an underscore to the argument name in order to make the argument name legal. This patch adds 'in', 'next', and 'self' keywords to dtrace.py. Also drop the unnecessary argument name lstrip() call. The Arguments.build() method already ensures there is no space around argument names. Furthermore it is misleading to do the lstrip() *after* checking against keywords because the keyword check would not match if spaces were in the name.

2012-04-18tracetool: Rewrite infrastructure as python modulesLluís Vilanova5-666/+580
The tracetool script is written in shell and has hit several portability problems due to shell quirks or external tools across host platforms. Additionally the amount of string processing and lack of real data structures makes it tough to implement code generator backends for tracers that are more complex. This patch replaces the shell version of tracetool with a Python version. The new tracetool design is: scripts/tracetool.py - top-level script scripts/tracetool/backend/ - tracer backends live here (simple, ust) scripts/tracetool/format/ - output formats live here (.c, .h) There is common code for trace-events definition parsing so that backends can focus on generating code rather than parsing input. Support for all existing backends (nop, stderr, simple, ust, and dtrace) is added back in follow-up patches.

2012-04-12kvm: add flightrecorder scriptStefan Hajnoczi1-0/+126
The kvm kernel module includes a number of trace events which can be useful when debugging system behavior. Even on production systems these trace events can be used to observe guest behavior and identify the source of problems. The kvm_flightrecorder script is a command-line wrapper for the /sys/kernel/debug/tracing interface. Kernel symbols do not need to be installed. This script captures a fixed-size buffer of KVM trace events. Recent events overwrite the oldest events when the buffer size is exceeded and it is possible to leave KVM tracing enabled for any period of time with just a fixed-size buffer. If the buffer is large enough this script is a useful tool for collecting detailed information after an issue occurs with a guest. Hence the name "flight recorder". The script can also be used in 'tail' mode to simply view KVM trace events as they occur. This is handy for development and to ensure that the guest is indeed running.

2012-03-31Fix conversion from lower to upper case with Turkish localeStefan Weil2-5/+5
Some locale settings let make fail or create wrong results because tr '[:lower:]' '[:upper:]' which is used to convert from lower to upper case depends on the locale. With locale tr_TR.UTF-8, lower case 'i' is not converted to 'I'. This results in wrong entries in config-host.h like these ones: #define CONFIG_QEMU_PREFiX "/usr/local" #define CONFIG_QEMU_BiNDiR "/usr/local/bin" This problem was reported by Emre Ersin. The same problem occurs when configure creates the target specific files config-target.mak. They get wrong declarations: TARGET_CRiS=y TARGET_i386=y TARGET_MiCROBLAZE=y TARGET_MiPS64=y TARGET_MiPS=y TARGET_UNiCORE32=y It is sufficient to restrict the conversion to the characters a-z. Using this explicit range avoids the dependency on the locale settings and is also shorter. v2: POSIX says that 'tr a-z' is unspecified outside of the POSIX locale, so we must set LC_ALL=C to make sure that we are using POSIX (hint from Eric Blake, thanks).

2012-03-30qtest: add test frameworkAnthony Liguori1-0/+5
The idea behind qtest is pretty simple. Instead of executing a CPU via TCG or KVM, rely on an external process to send events to the device model that the CPU would normally generate. qtest presents itself as an accelerator. In addition, a new option is added to establish a qtest server (-qtest) that takes a character device. This is what allows the external process to send CPU events to the device model. qtest uses a simple line based protocol to send the events. Documentation of that protocol is in qtest.c. I considered reusing the monitor for this job. Adding interrupts would be a bit difficult. In addition, logging would also be difficult. qtest has extensive logging support. All protocol commands are logged with time stamps using a new command line option (-qtest-log). Logging is important since ultimately, this is a feature for debugging.

2012-03-27qapi: untangle next_listPaolo Bonzini1-2/+2
Right now, the semantics of next_list are complicated. The caller must: * call start_list * call next_list for each element *including the first* * on the first call to next_list, the second argument should point to NULL and the result is the head of the list. On subsequent calls, the second argument should point to the last node (last result of next_list) and next_list itself tacks the element at the tail of the list. This works for both input and output visitor, but having the visitor write memory when it is only reading the list is ugly. Plus, relying on *list to detect the first call is tricky and undocumented. We can initialize so->entry in next_list instead of start_list, leaving it NULL in start_list. This way next_list sees clearly whether it is on the first call---as a bonus, it discriminates the cases based on internal state of the visitor rather than external state. We can also pull the assignment of the list head from generated code up to next_list.

2012-03-24Support utf8 chars in pod docsMichael Tokarev1-0/+9
We've at least one UTF8 char in the qemu texi doc: $ grep Tibor qemu-doc.texi by Tibor "TS" Schütz. $ man ./qemu.1 | grep Tibor by Tibor "TS" SchA~Xtz. This patch allows utf8 in man/pod docs. Initially it was split into two parts and sent on 2012-02-02. Resending it again (3rd time) now in merged form. If any other generalizations of $(POD2MAN) are needed it can be done in a separate patch. Current form of $(POD2MAN) is choosen to be able to easily change it if some implementation does not support utf8 or resulting output has issues with local man(1) program/macros. First, add @documentencoding in scripts/texi2pod.pl: Currently our texi2pod ignores @documentencoding even if it is set properly in *.texi files. This results in a mojibake in documents generated from qemu.pod (which is generated from qemu-doc.texi by texi2pod), because the rest of the tools assumes ASCII encoding. This patch recognizes first @documentencoding in input and places it at the beginning of output as =encoding directive. Second, run pod2man with --utf8 option to enable utf8 in manpages: This option makes no difference for manpages which contains only ascii chars. But for manpages with actual UTF8 characters (qemu docs contains these), this change allows to see real characters instead of mojibakes or substitutes.

2012-03-12tracetool: Omit useless QEMU_*_ENABLED() checkStefan Hajnoczi1-3/+1
SystemTap provides a "semaphore" that can optionally be tested before executing a trace event. The purpose of this mechanism is to skip expensive tracing code when the trace event is disabled. For example, some applications may have trace events that format or convert strings for trace events. This expensive processing should only be done in the case where the trace event is enabled. Since QEMU's generated trace events never have such special-purpose code, there is no reason to add the semaphore check.

During a parallel build, the two commands may be invoked in parallel; this opens up a race, where the second invocation trashes a file supposedly produced during the first, and now in use by a dependent command.
