Linux/DRA746: SGX: Compile shader offline

Ikshwaku Chauhan

Part Number: DRA746

Tool/software: Linux

Hello Team,

We use custom h/w and software based on DRA746 and VSDK 3.04. Have one query related to Shader compilation.

We wants to compile the shaders on windows and use them directly in OpenGLES programs instead of compiling the shaders at runtime.

I have checked the PVRShaderEditor, but this tool can only be used for resolving the compilation errors.

Could you please help us here.

Regards,

Hello Yordan,

I have checked these links and I have the required offline compiler and I able to use it with PVRShaderEditor.

As per this link "https://forums.imgtec.com/t/need-opengl-es-2-0-offline-compiler/2671" we can use "glGetProgramBinaryOES" api for generating the shader binaries.

My query is related to compile shaders with available offline compiler and generate the shader binaries to use them later in programs.

Regards,

Hi Ikshwaku,

If the need is for the offline compiler, you can find a copy of it in the
below location.

git.ti.com/.../jacinto6evm

Can you confirm on the version you are using, you can do `cat
/proc/pvr/version` on your target.

You could also generate binary shaders through `glGetProgramBinaryOES` GLES
extension API. You would have to save the binary on the first run and can use
the binary in the subsequent runs.

Thanks,
Gowtham
