Android RenderScript signal 7 (SIGBUS), code 1 (BUS_ADRALN), fault addr 0x76f458b4 Adreno 306, 320

Question

I'm having problem on two test devices- Samsung Galaxy J5 ,Android 6.0.1, Kernel 3.10.49-11903637, Build MMB29M.J510FNXXU2AQG3 GPU Adreno 306, and Nexus 4 -GPU Adreno 320. I am trying to calculate the sharpness of the bitmap, by making two filtrations on bitmap. Sampled size of original bitmap is used, with size less than 64x64, for performance. Same code works just fine on Samsung Galaxy S6, Sony Xperia Z3, Samsung Galaxy Tab 10.1 (2016), Huawei P10. Tried changing input parameters, used different images, different coefficients, but on J5 it always crashes.

Update: For photos taken on other devices, pass successfully when are rotated to portrait,( height bigger than width). However photos taken on same device, crash no mater how i rotate them.

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)

On this last line, program crashes with native error:

Answer 1

So the problem got solved by passing Script.LaunchOptions to convolve3x3.forEach function, limiting intersection over which kernel will operate. Setting it within the range of the allocation did the job.

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)
