Hi.
I developed to blit(compose) 2D surface(gcoSURF_SetBuffer of DRM memory(decoded NV12 with ducati(IVA-HD))) and 2D surface(ARGB) on 2DGPU(GC320) as TI help. DRM memory(decoded NV12 with ducati(IVA-HD)) should make omap_bo_new with OMAP_BO_WC.
It is OK.
I need to blit(compose) rendered surface of 3DGPU(gbm lib) and 2D surface(ARGB) on 2DGPU(GC320).
Can you support 2D GPU use gcoSURF_SetBuffer with vaddr of rendered surface of 3DGPU(gbm lib) ?
<CODE>
req.handle = gbm_bo_get_handle( lpBo ).u32; /* rendered */
drmCommandWriteRead(m_DrmDeviceFD, DRM_OMAP_GEM_INFO, &req, sizeof(req));
...
mmap(0, size, PROT_READ | PROT_WRITE, MAP_SHARED, m_DrmDeviceFD, offset); /* ok */
...
gcoSURF_SetBuffer on 2DGPU is died as below it.
