3D-Tech News Around The Web / Qualcomm Adreno GPU driver 17.04.2014
« Last post by Stefan on April 18, 2014, 04:42:11 PM »Quote
User-mode driver binaries for Qualcomm’s Adreno 3xx GPU on Nexus 4, 5 & 7 devices running Google Android 4.4.2 KitKat
Updated 17 Apr 14
This release contains a developer preview of the user-mode driver binaries for Qualcomm’s Adreno 3xx GPU on Nexus 4, Nexus 5, and Nexus 7 devices running Google Android 4.4.2 KitKat. It has been tested with the KOT49H factory image. This release is intended only for developers, and does not meet our customer release quality. Refer to the included release notes for a list of fixes and enhancements.
I recommend to backup system partition before flashing.
After successful flashing OpenGL ES 3.0 should have raised from V@53.0 to V@66 and the number of extensions from 43 to 46 (on Nexus 4 at least).
I will check what else it fixes besides in the release notes below.
Code: [Select]
Fix an intermittent crash that may happen when running dEQP-GLES2.functional.light_amount.1dir.
Fix rendering corruption in GFXBench Manhattan caused by out-of-sync VBO cache.

Allow 0 as an argument to the GLSL #line directive, as per spec.
Remove erroneous report of paletted texture formats from the GL_COMPRESSED_TEXTURE_FORMATS query when GL_OES_compressed_paletted_texture is not reported in the extension string list.
Fix a possible segmentation fault in glTexImage2D().
Fix mishandling of trailing whitespace after a GLSL #if directive.
Fix intermittent crashes from GLSL symbol table corruption.
Fix a scenario where performing a glQueryCounter() followed by glGet(GL_TIMESTAMP_EXT) and taking the difference between the two could result in a negative value, wrongly indicating a negative latency between the CPU and GPU.
Fix possible page fault when a shared EGL surface has a depth buffer.
Fix intermittent crash in Chrome browser that sometimes occurred while rotating and locking the device at the same time.
Add thread-safety for EGL images.
Fix Adreno Profiler shader override issues with shaders that use uniforms.

Create separate scope for if/if else/else statements in GLSL as per spec.
Fix incorrect conversion of negative float values to FALSE in glGetBoolean().
Reject invalid GLSL version numbers in #version directive.
Allow all integer constant expressions in GLSL #line directives.
Add driver support for EGL_KHR_create_context extension.
Fix rendering corruption with TGCOM24 app.
Fix the total count of uniform samplers when uniform samplers are used both in the vertex and fragment shader.
Fix erroneous compile errors for certain YUV GLSL shaders.
Fix a crash when indexing a sampler by a non-constant index in GLSL.

Add processor selection in Renderscript, to measure GPU and CPU execution times and choose the fastest processor for a given kernel to execute.
If a texture is changed in a shared context and the texture is bound or rebound in the current context, then update texture samplers to ensure the changes are visible in the current context, in accordance with Rule 4, section D.3.3 of the OpenGL® ES 3.0 spec.
Fast clear is not compatible with stencil mask, so disable it when stencil mask is enabled.
Allow glBlitFramebuffer() to blit within the default framebuffer if color buffers are for different surfaces.
Do not kill the application in case of GPU reset.
Fix problems with some uniforms in override programs not being set correctly by Adreno Profiler.

Cleaner handling for internal compiler error cases for UBOs.
Faster rsGetElementAt() and rsSample() runtime performance for programs that access many Allocation objects.
Improved stability when compiling complex RenderScript code.
Allow a count of zero in calls to glDrawBuffers() as per spec.
Fix errors in calculation of 2D texture array slice sizes for NPOT textures.
Generate GL_INVALID_VALUE from glTexStorage2D() and glTexStorage3D() when width, height, or depth exceed supported size.
Fix behavior of glGetFramebufferAttachmentParameteriv() to properly return GL_FRAMEBUFFER_DEFAULT for the default framebuffer instead of returning GL_NONE. (See OpenGL® ES Version 3.0 spec §6.1.13.)
Change glCopyTexImage2D() to prohibit SNORM as a destination format, as per Table 3.15 of the OpenGL® ES Version 3.0 spec.
Relaxed restrictions on the width and height parameters of glCompressedTexSubImage2D() to allow updates of 1x1 and 2x2 miplevels for ETC2/EAC formats. The incoming data buffer must still have its width and height padded to four, as required by ETC2/EAC, but the width and height parameters to the function call may reflect the actual texture dimensions.

Fix reported value of gl_MaxVertexTextureImageUnits for GLES 3.0 hardware.
Add support for the following built-in constants in GLSL 3.0:
gl_MaxVertexOutputVectors

ACML Beta 6.0 Release Leverages the Power of Heterogeneous Compute
AMD is releasing a Beta of the next release of the AMD Core Math Library (ACML). ACML provides a free set of thoroughly optimized and threaded math routines for HPC, scientific, engineering and related compute-intensive applications. Version 6.0 sees ACML going in a direction that it has not attempted before, which is to support heterogeneous computing. AMD designs both high performance CPU and GPU based cores, and ACML is aiming to take the best advantage of both.
