Android RenderScript 신호 7 (SIGBUS), 코드 1 (BUS_ADRALN), 오류 addr 0x76f458b4 Adreno 306, 320

Question

삼성 갤럭시 J5, 안드로이드 6.0.1, 커널 3.10.49-11903637, 빌드 MMB29M.J510FNXXU2AQG3 GPU Adreno 306 및 Nexus 4 -GPU Adreno 320. 비트 맵에서 두 번의 필터링을 수행하여 비트 맵의 ​​선명도를 계산하려고합니다. 샘플 비트 맵의 ​​샘플 크기는 성능을 위해 64x64 이하의 크기로 사용됩니다. 동일한 코드는 삼성 Galaxy S6, Sony Xperia Z3, Samsung Galaxy Tab 10.1 (2016), Huawei P10에서 잘 작동합니다. 입력 매개 변수를 변경하려고했지만 다른 이미지와 다른 계수를 사용했지만 J5에서는 항상 충돌합니다.

업데이트 : 다른 장치에서 촬영 한 사진의 경우 세로로 회전하면 (너비보다 큰 높이) 성공적으로 통과합니다. 그러나 같은 장치에서 찍은 사진은 내가 회전시키는 방법을 손상시키지 않습니다. 이 마지막 줄에

val options = BitmapFactory.Options() 
options.inJustDecodeBounds = true 
BitmapFactory.decodeFile(imagePath, options) 

val imageSize = SizeT(options.outWidth, options.outHeight) 
val imageScale = imageSize.scaleToFitInSize(SizeT(64, 64)) 
val imageScaledSize = imageSize.scale(imageScale.toDouble()) 
options.inJustDecodeBounds = false 
options.inSampleSize = ImageUtils.calculateInSampleSize(imageSize, imageScaledSize, 1.0) 

val sourceBitmap = BitmapFactory.decodeFile(imagePath, options) 

var sobelScript: ScriptC_sobel? = null 
var inputAllocation: Allocation? = null 
var outputAllocation: Allocation? = null 
var intermediateAllocation: Allocation? = null 
var convolve3x3: ScriptIntrinsicConvolve3x3? = null 
var renderScript: RenderScript? = null 

val imageWidth = sourceBitmap.width 
val imageHeight = sourceBitmap.height 

renderScript = RenderScript.create(ApplicationContext.ApplicationContext()) 
inputAllocation = Allocation.createFromBitmap(renderScript, sourceBitmap) 
val typeInBuilder = Type.Builder(renderScript, Element.F32_4(renderScript)).setX(imageWidth).setY(imageHeight ) 

// Allocation where to store the sum result (for output purposes) 
val coefficientsGx = floatArrayOf(-1f, 0f, 1f, -2f, 0f, 2f, -1f, 0f, 1f) 
val coefficientsGy = floatArrayOf(-1f, -2f, -1f, 0f, 0f, 0f, 1f, 2f, 1f) 

intermediateAllocation = Allocation.createTyped(renderScript, typeInBuilder.create()) 

convolve3x3 = ScriptIntrinsicConvolve3x3.create(renderScript, Element.F32_4(renderScript)) 
convolve3x3.setInput(inputAllocation) 
convolve3x3.setCoefficients(coefficientsGx) 
convolve3x3.forEach(intermediateAllocation) 

이 프로그램은 원시 오류로 충돌 :

Answer 1

가 그래서 문제가 convolve3x3.forEach 기능에 Script.LaunchOptions를 전달 커널이 작동하는 동안 교차로를 제한함으로써 해결되었다. 할당 범위 내에서 설정하면 작업이 수행됩니다.

renderScript = RenderScript.create(ApplicationContext.ApplicationContext()) 
inputAllocation = Allocation.createFromBitmap(renderScript, sourceBitmap) 
val typeInBuilder = Type.Builder(renderScript, Element.F32_4(renderScript)).setX(imageWidth).setY(imageHeight ) 
val launchOptions = Script.LaunchOptions() 
launchOptions.setX(0, imageWidth-1) 
launchOptions.setY(0, imageHeight-1) 
launchOptions.setZ(0, 1) 

// Allocation where to store the sum result (for output purposes) 
val coefficientsGx = floatArrayOf(-1f, 0f, 1f, -2f, 0f, 2f, -1f, 0f, 1f) 
val coefficientsGy = floatArrayOf(-1f, -2f, -1f, 0f, 0f, 0f, 1f, 2f, 1f) 

intermediateAllocation = Allocation.createTyped(renderScript, typeInBuilder.create()) 

convolve3x3 = ScriptIntrinsicConvolve3x3.create(renderScript, Element.F32_4(renderScript)) 

convolve3x3.setInput(inputAllocation) 
convolve3x3.setCoefficients(coefficientsGx) 
convolve3x3.forEach(intermediateAllocation, launchOptions)
