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.

2012-04-05tracetool: Forbid argument name 'next'Kevin Wolf1-0/+4
It has happened more than once that patches that look perfectly sane and work with simpletrace broke systemtap because they use 'next' as an argument name for a tracing function. However, 'next' is a keyword for systemtap, so we shouldn't use it. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

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.

Make's multiple output syntax x.c x.h: x.template gen < x.template actually invokes the command once for x.c and once for x.h (with differing $@ in each invocation). 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. The various qapi code generators are susceptible to this; fix by making them generate just one file per invocation.

2011-09-17trace: allow PRI*64 at beginning and ending of format stringStefan Hajnoczi1-7/+13
The tracetool parser only picks up PRI*64 and other format string macros when enclosed between double quoted strings. Lift this restriction by extracting everything after the closing ')' as the format string: cpu_set_apic_base(uint64_t val) "%016"PRIx64 ^^ ^^ One trick here: it turns out that backslashes in the format string like "\n" were being interpreted by echo(1). Fix this by using the POSIX printf(1) command instead. Although it normally does not make sense to include backslashes in trace event format strings, an injected newline causes tracetool to emit a broken header file and I want to eliminate cases where broken output is emitted, even if the input was bad.
