| * Fix Class.getDex.Elliott Hughes2013-07-311-0/+14
| | | | | | | | | | | | | | | | Dalvik doesn't check its own .so when looking for JNI methods, so manually register Class.getDex. Also fix a bug in that native method's implementation. Change-Id: Ic87484fac888e9eea0e5d51a2d2447eee860ece5

* | Add low memory mode option.Mathieu Chartier2013-07-131-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added a low memory mode option which can be enabled by passing the flag "-XX:LowMemoryMode" to the VM. Changed dvmHeapSourceAlloc to use mspace_malloc and madvise page aligned regions of allocations back to the kernel if low memory mode is enabled. No measurable performance penalty on a benchmark which does 4 million object allocations. This seems to reduce the Dalvik total PSS by 10 - 15% on devices with large bitmaps (such as manta or flo). Another change is that cards are madvised instead of memset when cleared if low memory mode is enabled. This saves a minor amount of memory at the cost of having slightly more page faults.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was supposed to help find bugs, but in practice (unlike the locale reference limit and the pinned array limit) doesn't. What it does do is cause well-behaved code to fail if its allocation rate is high. This has caused trouble for both audio and graphics code running on eng builds.

* | | JIT tuning; set cache size on command linebuzbee2013-05-231-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* | | Don't emit a warning message on missing PR_SET_NO_NEW_PRIVSNick Kralevich2013-05-071-7/+4
|/ / | | | | | | | | | | | | | | | | | | | | | | If the kernel doesn't support PR_SET_NO_NEW_PRIVS, then don't print a warning message. The warning message only serves to confuse other people. This change assumes that, if EINVAL is returned, the kernel is an old kernel. Newer kernels have no option to disable PR_SET_NO_NEW_PRIVS, so IMHO, this is a fair assumption.

* | Include user identifier in external storage paths.Jeff Sharkey2012-09-071-0/+31
|/ | | | | | | | | | | | | | | | | | | | | | | | | When building external storage paths, always include user in path to enable cross-user paths and aid debugging. Each Zygote process continues to only have access to the appropriate user-specific emulated storage through bind mounts. A second set of mounts continue supporting legacy /sdcard-style paths. For example, a process running as owner has these mount points: /storage/emulated_legacy /storage/emulated_legacy/Android/obb /storage/emulated/0 /storage/emulated/obb This change also creates two nested namespaces around zygote. The first namespace is created when the zygote starts, and it holds a single writable tmpfs, since rootfs is ro. The second namespace is created quickly after forking, and is used to hold the private user-specific bind mounts. (This design saves us from creating a tmpfs-per-process.)

* [X86] X86 trace JIT compiler supportDong-Yuan Chen2012-07-201-17/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Add a dual clock profiler tracing mode.Jeff Brown2011-06-271-1/+10
| | | | | | | | | | | | | | | | | | | Dalvik previously supported using either the thread-cpu clock or the real time clock as the timebase for profiler traces. This change adds a dual clock mode where both thread-cpu time and real time timestamps are collected. Using dual clock mode significantly improves TraceView ability to accurately reconstruct the global timeline of events, particularly on SMP systems. For now, thread-cpu mode remains the default. Dual clock mode can be enabled by running the following command and restarting the system server. adb shell setprop dalvik.vm.extra-opts -Xprofile:dualclock Change-Id: I8c0d91a99aa6829dadea328e54dc1225d9827391
