Android RenderScript 信号 7 (SIGBUS)，代码 1 (BUS_ADRALN)，故障地址 0x76f458b4 Adreno 306、320
Android RenderScript signal 7 (SIGBUS), code 1 (BUS_ADRALN), fault addr 0x76f458b4 Adreno 306, 320
我在两个测试设备上遇到问题 - 三星 Galaxy J5，Android 6.0.1，内核 3.10.49-11903637，构建 MMB29M.J510FNXXU2AQG3 GPU Adreno 306 和 Nexus 4 -GPU Adreno 320 .
我试图通过对位图进行两次过滤来计算位图的清晰度。使用原始位图的采样大小，大小小于 64x64，以提高性能。
相同的代码在三星 Galaxy S6、索尼 Xperia Z3、三星 Galaxy Tab 10.1 (2016)、华为 P10 上运行良好。
试过改输入参数，用不同的图片，不同的系数，但是在J5上总是闪退
更新：
对于其他设备拍摄的照片，旋转为纵向（高度大于宽度）时成功通过。
但是在同一台设备上拍摄的照片，无论我如何旋转它们都会崩溃。

所以通过将 Script.LaunchOptions 传递给 convolve3x3.forEach 函数解决了问题，限制了内核将运行的交集。将其设置在分配范围内就可以了。
