| * JIT tuning; set cache size on command linebuzbee2013-05-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tuning knobs for triggering trace compilation for the JIT had not been revisited for several years. In that time, the working set of some applications have significantly increased, leading to frequent cache overlows & flushes. This CL adds the ability to set the maximum size of the JIT's cache on the command line, and we expect to use different settings depending on device configuration (rule of thumb: 1K for each 1M for system RAM, with 2M limit). Additionally, the trace compilation trigger has been tightened to limit the compilation of cold traces. Change-Id: Ice22c5d9d46a93e465c57dd83f50ca3912f1672e

* Print the locker thread when waiting on an objectPal Szasz2012-12-061-0/+3
| | | | | | | | | | | | | When dumping stacktraces, and if one thread is blocked due to a call to Object.wait, the dump will just tell us the object pointer it is waiting on, but not the thread which actually locked the object. This patch tries to extract that informatation as well. Note that this information is not always available, since maybe no other thread aquired the lock yet.

* [X86] X86 trace JIT compiler supportDong-Yuan Chen2012-07-204-20/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides a fully functional x86 trace JIT compiler for Dalvik VM. It is built on top of the existing x86 fast interpreter with bug fixes and needed extension to support trace JIT interface. The x86 trace JIT code generator was developed independent of the existing template-based code generator and thus does not share exactly the same infrastructure. Included in this patch are: * Deprecated and removed the x86-atom fast interpreter that is no longer functional since ICS. * Augmented x86 fast interpreter to provide interfaces for x86 trace JIT compiler. * Added x86 trace JIT code generator with full JDWP debugging support. * Method JIT and self-verification mode are not supported. The x86 code generator uses the x86 instruction encoder/decoder library from the Apache Harmony project. Additional wrapper extension and bug fixes were added to support the x86 trace JIT code generator. The x86 instruction encoder/decoder is embedded inside the x86 code generator under the libenc subdirectory.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old output just told you what functions were being called and made no attempt to show you their arguments. The new output was sufficient to debug an actual problem with an app we don't have the source to. Still to do: 0. an easier way for third-party developers to enable this. 1. the primitive type arguments to SetIntField and so forth. 2. return values. A few examples of the new output... A decoded jclass: JNI: libcore.io.Posix.readBytes called IsInstanceOf((JNIEnv*)0x9618470, 0x28100015, java.lang.Class<byte[]>) A decoded jfieldID: JNI: libcore.io.Posix.ioctlInt called GetIntField((JNIEnv*)0x9618470, 0x5cb00011, java.io.FileDescriptor.descriptor) A decoded jmethodID (the FileDescriptor constructor): JNI: libcore.io.Posix.open called NewObject((JNIEnv*)0x9780480, java.lang.Class<java.io.FileDescriptor>, java.io.FileDescriptor.<init>()V, ...) A const char*: JNI: libcore.io.Posix.getsockoptLinger called NewStringUTF((JNIEnv*)0x9618470, "getsockopt") A jint release mode: JNI: libcore.io.Posix.writeBytes called ReleaseByteArrayElements((JNIEnv*)0x9780480, 0x2700009, (void*) 0xf5f623c4, JNI_ABORT) The -verbose:jni option now turns on a bit more output about JNI_OnLoad calls but no longer causes any logging of calls to JNIEnv or JavaVM functions. The old -Xjnitrace: option has been extended to enable this new tracing for the native methods that it covers. They go very well together for debugging purposes. I've also made us a bit more verbose if we fail to initialize. In the longer term I think we want to just abort if we hit any failure during startup, but my extra logging will save us a bit of time next time we have one of these failures (this one was caused for me by only having one half of the finalizer watchdog change; I was missing the libcore side).
