AM5728: Reading DRM buffer in galRunTest2_drm.c

Hi,

What processor is this? Which SDK?

Hi, Biser
my processor is AM5728
I use this sample: git.ti.com/.../ti-gc320-test
and I find galRunTest2_drm.c in this thread : e2e.ti.com/.../565351

The software team have been notified. They will respond here.

Hi Bossun,
This application creats target(destination) surface with drm buffers and source surfaces in the dynamic library are created with its internal memory. From your statement , looks like you are trying to create source surfaces also with drm buffers. Is it correct?
I have tried this and and has worked, both source and destination surfaces are drm buffers.

Can you share me which use case in units you are trying to modify? and what are the changes?

Hi, Ramprasad

Thanks for reply.

Can you post your code or teach me your step?

The following  is my part code in init() function:

gcmONERROR(gcoSURF_Construct(t2d->runtime->hal,
                               	   t2d->srcWidth,
                               	   t2d->srcHeight,
                               	   1,
				   gcvSURF_BITMAP,
                               	   t2d->srcFormat,
                               	   gcvPOOL_USER,
                               	   &t2d->srcSurf));
    
	gcmONERROR(gcoSURF_GetSize(t2d->srcSurf,
								 &t2d->srcWidth,
								 &t2d->srcHeight,
								 gcvNULL));
    
    //change by Bossun Wang
    printf("t2d->srcWidth: %d\n", t2d->srcWidth);
    printf("t2d->srcHeight: %d\n", t2d->srcHeight);

    unsigned long phys = ~0U;

	gcmONERROR(gcoSURF_SetBuffer(t2d->srcSurf,
                    gcvSURF_BITMAP,
                    t2d->srcFormat,
                    t2d->srcStride,
                    src_vaddr,
                    phys));
    
    gcmONERROR(gcoSURF_Lock(t2d->srcSurf,
							  &t2d->srcPhysAddr,
							  &t2d->srcVirtAddr));

Hi, Ramprasad,
Thank you for your guidance.

I used gcoSURF_SetWindow(), it work fine.

But I set that src format is gcvSURF_YUY2, the following code is error in Render() function:

// start rendering sequence
	gcmONERROR(gco2D_SetColorSourceEx(egn2D,
									  t2d->srcPhysAddr,
									  t2d->srcStride,
									  t2d->srcFormat,
									  gcvSURF_0_DEGREE,
									  t2d->srcWidth,
                                      t2d->srcHeight,
									  gcvFALSE,
									  gcvSURF_OPAQUE,
									  0));

Render(258) failed:gcvSTATUS_NOT_SUPPORTED

How to fix it?

Best regards,

Bossun
