Linux/AM5728: H.264 buffers question

Tool/software: Linux

Hi,

I want to enable cache for buffers allocated using omap_bo_new(). As pointed out in this thread https://e2e.ti.com/support/arm/sitara_arm/f/791/t/491377?AM57x-Slow-memory-access-of-shared-memory

CMEM buffers instead of omap_bo_new(), can I use these buffers with the h264 HDVICP encoder and decoder?

Hello,

The buffers submitted to IPUMM need to be in Tiler.

Hi,

Is the OMAP_BO_CACHED feature of omap_bo_new() fixed in the latest PSDK release?
