The benchmark creates a set of DSOs that mimic the work involved in loading the current version of libandroid_servers.so. The synthetic benchmark has roughly the same number of libraries with roughly the same relocations. Currently, on a local aosp_walleye build that includes recent performance improvements (including the Neon-based CL I3983bca1dddc9241bb70290ad3651d895f046660), using the "performance" governor, the benchmark reports these scores: $ adb shell taskset 10 \ /data/benchmarktest64/linker-reloc-bench/linker-reloc-bench \ --benchmark_repetitions=20 --benchmark_display_aggregates_only=true ... -------------------------------------------------------------------------------- Benchmark Time CPU Iterations -------------------------------------------------------------------------------- BM_linker_relocation/real_time_mean 70048 us 465 us 20 BM_linker_relocation/real_time_median 70091 us 466 us 20 BM_linker_relocation/real_time_stddev 329 us 8.29 us 20 $ adb shell taskset 10 \ /data/benchmarktest/linker-reloc-bench/linker-reloc-bench \ --benchmark_repetitions=20 --benchmark_display_aggregates_only=true ... -------------------------------------------------------------------------------- Benchmark Time CPU Iterations -------------------------------------------------------------------------------- BM_linker_relocation/real_time_mean 83051 us 462 us 20 BM_linker_relocation/real_time_median 83069 us 464 us 20 BM_linker_relocation/real_time_stddev 184 us 8.91 us 20 Test: manual Bug: none Change-Id: I6dac66978f8666f95c76387093bda6be0151bfce

2019-11-11Make system property reads wait-freeDaniel Colascione
Right now, when we read a system property, we first (assuming we've already looked up the property's prop_info) read the property's serial number; if we find that the low bit (the dirty bit) in the serial number is set, we futex-wait for that serial number to become non-dirty. By doing so, we spare readers from seeing partially-updated property values if they race with the property service's non-atomic memcpy to the property value slot. (The futex-wait here isn't essential to the algorithm: spinning while dirty would suffice, although it'd be somewhat less efficient.) The problem with this approach is that readers can wait on the property service process, potentially causing delays due to scheduling variance. Property reads are not guaranteed to complete in finite time right now. This change makes property reads wait-free and ensures that they complete in finite time in all cases. In the new approach, we prevent value tearing by backing up each property we're about to modify and directing readers to the backup copy if they try to read a property with the dirty bit set. (The wait freedom is limited to the case of readers racing against *one* property update. A writer can still delay readers by rapidly updating a property --- but after this change, readers can't hang due to PID 1 scheduling delays.) I considered adding explicit atomic access to short property values, but between binary compatibility with the existing property database and the need to carefully handle transitions of property values between "short" (compatible with atomics) and "long" (incompatible with atomics) length domains, I figured the complexity wasn't worth it and that making property reads wait-free would be adequate.

2019-10-08Reimplement the <ctype.h> is* functions.Elliott Hughes
Following on from the towlower()/towupper() changes, add benchmarks for most of <ctype.h>, rewrite the tests to cover the entire defined range for all of these functions, and then reimplement most of the functions. The old table-based implementation is mostly a bad idea on modern hardware, with only ispunct() showing a significant benefit compared to any other way I could think of writing it, and isalnum() a marginal but still convincingly genuine benefit. My new benchmarks make an effort to test an example from each relevant range of characters to avoid, say, accidentally optimizing the behavior of `isalnum('0')` at the expense of `isalnum('z')`. Interestingly, clang is able to generate what I believe to be the optimal implementations from the most readable code, which is impressive. It certainly matched or beat all my attempts to be clever! The BSD table-based implementations made a special case of EOF despite having a `_ctype_` table that's offset by 1 to include EOF at index 0. I'm not sure why they didn't take advantage of that, but removing the explicit check for EOF measurably improves the generated code on arm and arm64, so even the two functions that still use the table benefit from this rewrite.

This reverts commit 3bf27c86d1327a5a66bf06af07027c4f1a37d358. Disable the 32-bit glibc target. We're not interested in benchmarking that target, and the bench_noop_nostl executable doesn't build when ASAN is turned on, because the libclang_rt.asan_cxx-i386.a lib contains ubsan_type_hash_itanium.cc.o, which needs __dynamic_cast and various STL typeinfo variables. The equivalent libclang_rt.asan_cxx-x86_64.a lib doesn't have ubsan_type_hash_itanium.cc.o in it.

2019-09-26benchmarks: remove more boilerplate.Elliott Hughes
Many of our benchmarks are basically just "call one function with a fixed argument". We don't need to keep repeating all the boilerplate for that. This also ensures we don't forget the benchmark::DoNotOptimize, which -- in addition to being a good idea in general -- specifically solves the problem with gettid benchmark and provides a more accurate result by removing the indirection through a function pointer.

2019-09-25Add benchmarks that run simple programsRyan Prichard
Specifically, test the wall-clock time for running: * a C program that does nothing (i.e. no STL) * a C++ program that does nothing * a statically-linked C++ program * toybox true (in /system/bin and /vendor/bin) * mksh -c true (in /system/bin and /vendor/bin) Test: bionic-spawn-benchmarks Change-Id: I961850ec90004cac83088feab5783f4f27768be1
2019-09-24run-on-host fixesRyan Prichard
* Fix the path to bionic-benchmarks-glibc * Add symlinks for the toybox symlink commands. Each symlink bypasses the intermediate symlink in ${OUT}/system/bin and points to the final toybox binary. Suppress a bunch of warnings by skipping symlinks for non-existent files. The new spawn benchmarks try to run /system/bin/true. (They also try to run /vendor/bin/true and print an error.) * Quote "$@" * Use soong_ui.bash --dumpvars-mode to set a bunch of variables, rather than get_build_var, which invokes Soong once per variable. This reduces the "build/run-on-host.sh" runtime from 4s to 1.3s. * build/run-on-host.sh isn't executable and is only useful when it's sourced into another shell, so remove its shebang to reduce confusion.

2019-04-26Fix running tests/benchmarks on the host.Elliott Hughes
This was broken by all the mainline modules stuff. It's quite a bit hairier to set up now, given that we don't have an apexd on the host. An alternative might be to actually set up a fake /apex that points to the bootstrap directories?

2019-04-05Add malloc benchmarks.Christopher Ferris
Adding some benchmarks that keep a certain number of allocation around. This benchmark should not be used as an absolute for determining what is a good/bad native allocator. However, it should be used to make sure that numbers are not completely changed between allocator versions. Also update the malloc sql benchmark to match the same style as these new benchmarks.

Remove the need to add every benchmark to the list of all benchmarks. Also, add some hard-coding of the location of the benchmark executable.
