Android AARCH64 平台的 OpenCL 配置
开发环境
IDE: Android Studio 3.4.1
Android: 7.1
minSdkVersion: 25
targetSdkVersion: 26
JNI CMake: 3.4.1
ABI: arm64-v8a
OpenCL: 1.2
配置 OpenCL 使用项目中的 so 库
这里以编译 openclTest.cpp 为 libopenclTest.so 并导入 OpenCL 的动态库为例
注1: 下列 so 库需要从开发板上 pull 到项目中，其中 libGLES_mali.so 用于驱动 OpenCL，其他库为依赖库
注2: 不同平台的驱动库位于不同位置，可以下载 OpenCL-Z 查看
注3: set_target_properties 中第一项参数设置了生成库的名称，例如设置为 openclTest，则生成 libopenclTest.so 库，这里使用了 lib_* 作为前缀，则生成liblib_*.so 库，实际开发中要避免这种情况
查看依赖库
objdump -x libGLES_mali.so | grep NEEDED

配置 OpenCL 使用 dlopen 打开开发板上的运行库
这种配置方法需要从 Github - KhronosGroup/OpenCL-Headers 仓库下载 OpenCL 的头文件，并且需要自行实现 OpenCL 的函数
注: 需要在源码中定义
CL_TARGET_OPENCL_VERSION 120，否则会报找不到版本号的错误

需要导入的 dlopencl.h 和 dlopencl.cpp 写在文末
OpenCL 使用
以下均以使用 dlopen 导入运行库的方式为例
- 定义 OpenCL 版本
#define CL_TARGET_OPENCL_VERSION 120
- 包含头文件
#include <CL/cl.h>
#include "dlopencl.h"
- 使用 Logcat 打印日志
由于 C 语言工作在 JNI 层，无法获取控制台，导致了 printf() 函数失效，这里使用 __android_log_print 方法打印日志到 Logcat
#include <android/log.h>
#define DEBUG
#ifdef DEBUG
#define LOG "LOG-TAG"
#define LOGD(...) __android_log_print(ANDROID_LOG_DEBUG, LOG, __VA_ARGS__)
#define LOGI(...) __android_log_print(ANDROID_LOG_INFO, LOG, __VA_ARGS__)
#define LOGW(...) __android_log_print(ANDROID_LOG_WARN, LOG, __VA_ARGS__)
#define LOGE(...) __android_log_print(ANDROID_LOG_ERROR, LOG, __VA_ARGS__)
#define LOGF(...) __android_log_print(ANDROID_LOG_FATAL, LOG, __VA_ARGS__)
#else
#define LOG
#define LOGD(...)
#define LOGI(...)
#define LOGW(...)
#define LOGE(...)
#define LOGF(...)
#endif
使用方法同 printf()，例:
LOGI("Device ID: %d", device_id);
- 创建用于初始化 OpenCL 的 JNI 接口
建议在同一个文件中编写多个操作 OpenCL 的函数，这里的初始化实际上是将操作 OpenCL 的变量建立为全局变量，通过 JNI 一次调用后其他函数再使用这些被初始化过的变量
定义变量
cl_uint num_device;
cl_uint num_platform;
cl_platform_id *platform;
cl_device_id *devices;
cl_int err;
cl_context context;
extern "C"
JNIEXPORT jint JNICALL
Java_com_example_opencltest_MainActivity_initOpencl(JNIEnv *env, jobject instance) {
initFns();
LOGI("getPlatformNum");
// 获取可用平台数量
err = clGetPlatformIDs(0, 0, &num_platform);
platform = (cl_platform_id*)malloc(sizeof(cl_platform_id)*num_platform);
LOGI("getPlatformIDs");
// 获取平台 ID
err = clGetPlatformIDs(num_platform, platform, nullptr);
if(err < 0) {
LOGE("clGetPlatformIDs failed");
return -1;
}
LOGI("getDeviceNum");
// 获取可用设备数量
err = clGetDeviceIDs(platform[0], CL_DEVICE_TYPE_GPU, 0, nullptr, &num_device);
devices = (cl_device_id*)malloc(sizeof(cl_device_id)*num_device);
LOGI("getDeviceIDs");
// 获取设备 ID
err = clGetDeviceIDs(platform[0], CL_DEVICE_TYPE_GPU, num_device, devices, nullptr);
if (err < 0) {
LOGE("clGetDeviceIDs failed");
return -1;
}
return 0;
}
使用 OpenCL 执行 Kernel 函数
通常编写 OpenCL 中的 Kernel 函数要求单独写在 *.cl 文件中，调用时使用 fopen 打开，将里面的代码作为字符串读入之后再进行 runtime 编译，比较麻烦，这里直接将整个 Kernel 函数写成字符串
本例中因为测试原因没有释放掉创建的资源
可以使用允许正则替换的编辑器例如 VSCode，先写好 Kernel 函数，然后使用正则表达式
(.*)选择所有行并将每一行作为一个参数($1)，替换为"$1\n"，例如替换前:int a = 0;，替换后:"int a = 0; "
注1: 经测试发现 OpenCL 在 PC 端允许每次调用任意数量的矢量数据，而在开发板上只允许一次调用 1.2.3.4.8.16 个
PC 端允许的矢量调用:
Integralgraph.s0
Integralgraph.s01
Integralgraph.s012
Integralgraph.s0123
Integralgraph.s01234
Integralgraph.s0123456
Integralgraph.s01234567
Integralgraph.s012345678
Integralgraph.s0123456789
Integralgraph.s0123456789a
Integralgraph.s0123456789ab
Integralgraph.s0123456789abc
Integralgraph.s0123456789abcd
Integralgraph.s0123456789abcde
Integralgraph.s0123456789abcdef
开发板允许的矢量调用:
Integralgraph.s0
Integralgraph.s01
Integralgraph.s012
Integralgraph.s0123
Integralgraph.s01234567
Integralgraph.s0123456789abcdef
所以在编写运行于 AARCH64 架构的 OpenCL Kernel 函数时需要将被调用的矢量数组分组相加
例如在 PC 端为
TableInteg1 = (int16)(Integralgraph[index1].sf*flagx0, Integralgraph[index4].s0123456789abcde);
在开发板中需要改为
TableInteg1 = (int16)(Integralgraph[index1].sf*flagx0, Integralgraph[index4].s01234567, Integralgraph[index4].s89ab, Integralgraph[index4].scde);
注2: 测试中发现 PC 端的 OpenCL 遇到数组越界问题会直接跳过不予处理，但在 AARCH64 中会导致执行失败
注3: AARCH64 平台上 OpenCL 能申请到的可调用内存远小于 PC 端，如果出现输入或输出的数据超出 OpenCL 申请到的内存可能会导致数据输出不完整，读取数据时错误代码返回 -14 等问题
先在 Activity 中调用 initOpencl()，初始化 OpenCL 及其平台和设备
