2016-01-27oslib-win32: always get java path from registryJinhyung Jo2-115/+84
Regardless of the architecture of the emulator(32bit or 64bit), always gets the java execution path from Windows registry. This commit would be helpful to reduce the java execution failure. Change-Id: I890bfa67ffdde36bbbd28678e196d7a50bce65a8 Signed-off-by: Jinhyung Jo <jinhyung.jo@samsung.com>
2015-09-14emulator: Fixed a bug Java path not found on Windows 64jinhyung.jo1-11/+9
The get_java_path function aways returns the first item of the JRE(or JDK) registry. The RegEnumKeyEx function's 4th argument type is [In, Out], But previous implementations have used without resetting it. So fix it and improved the 'while' statement.

2014-03-25osdep: initialize glib threads in all QEMU toolsStefan Hajnoczi1-0/+18
glib versions prior to 2.31.0 require an explicit g_thread_init() call to enable multi-threading. Failure to initialize threading causes glib to take single-threaded code paths without synchronization. For example, the g_slice allocator will crash due to race conditions. Fix this for all QEMU tool programs (qemu-nbd, qemu-io, qemu-img) by moving the g_thread_init() call from vl.c:main() into a new osdep.c:thread_init() constructor function. thread_init() has __attribute__((constructor)) and is automatically invoked by the runtime during startup. We can now drop the "simple" trace backend's g_thread_init() call since thread_init() already called it. Note that we must keep coroutine-gthread.c's g_thread_init() call which is located in a constructor function. There is no guarantee for constructor function ordering so thread_init() may only be called later.

2014-03-13rfifolock: add recursive FIFO lockStefan Hajnoczi2-0/+79
QemuMutex does not guarantee fairness and cannot be acquired recursively: Fairness means each locker gets a turn and the scheduler cannot cause starvation. Recursive locking is useful for composition, it allows a sequence of locking operations to be invoked atomically by acquiring the lock around them. This patch adds RFifoLock, a recursive lock that guarantees FIFO order. Its first user is added in the next patch. RFifoLock has one additional feature: it can be initialized with an optional contention callback. The callback is invoked whenever a thread must wait for the lock. For example, it can be used to poke the current owner so that they release the lock soon. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

This patch adds loading, stamp checking and initialization of modules. The init function of dynamic module is no longer directly called as __attribute__((constructor)) in static linked version, it is called only after passed the checking of presense of stamp symbol: qemu_stamp_$RELEASEHASH where $RELEASEHASH is generated by hashing version strings and content of configure script. With this, modules built from a different tree/version/configure will not be loaded. The module loading code requires gmodule-2.0. Modules are searched under - CONFIG_MODDIR - executable folder (to allow running qemu-{img,io} in the build directory) - ../ of executable folder (to allow running system emulator in the build directory) Modules are linked under their subdir respectively, then copied to top level of build directory for above convinience, e.g.: $(BUILD_DIR)/block/curl.so -> $(BUILD_DIR)/block-curl.so Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2014-01-22qemu-option: Add qemu_config_parse_qdict()Max Reitz1-0/+100
This function basically parses command-line options given as a QDict replacing a config file. For instance, the QDict {"section.opt1": 42, "section.opt2": 23} corresponds to the config file: [section] opt1 = 42 opt2 = 23 It is possible to specify multiple sections and also multiple sections of the same type. On the command line, this looks like the following: inject-error.0.event=reftable_load,\ inject-error.1.event=l2_load,\ set-state.event=l1_update This would correspond to the following config file: [inject-error "inject-error.0"] event = reftable_load [inject-error "inject-error.1"] event = l2_load [set-state] event = l1_update Signed-off-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

Using stdin with readline.c requires disabling echo and line buffering. Add a portable wrapper to set the terminal attributes under Linux and Windows. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2014-01-22readline: move readline to a generic locationStefan Hajnoczi2-0/+496
Now that the monitor and readline are decoupled, readline.h no longer belongs in include/monitor/. Put the header into include/qemu/. Move the source file into util/ so it can be linked as part of libqemuutil.a. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2014-01-17Revert "error: Don't use error_report() for assertion msgs."Peter Crosthwaite1-4/+4
This reverts commit d32934c84c72f57e78d430c22974677b7bcabe5d. The original implementation before this patch makes abortive error messages much more friendly. The underlying bug that required this change is now fixed. Revert. Signed-off-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@xilinx.com>
2014-01-15error: Don't use error_report() for assertion msgs.Peter Crosthwaite1-4/+4
Use fprintf(stderr instead. This removes dependency of libqemuutil.a on the monitor. We can further justify this change, in that this code path should only trigger under a fatal error condition. fprintf-stderr is probably the appropriate medium as under a fatal error conidition the monitor itself may be down and out for the count. So assertion failure messages should go lowest common denominator - straight to stderr. Fixes the build as reported by Kevin Wolf. Issue debugged and change suggested by Luiz Capitulino.

This is a boiler-plate _nofail variant of qemu_opts_create. Remove and use error_abort in call sites. null/0 arguments needs to be added for the id and fail_if_exists fields in affected callsites due to argument inconsistency between the normal and no_fail variants.
