Hi Sumit, I wanted to follow-up on the discussion we had at Plumbers with John and T.J. about (among other things) adding new heaps to the kernel. I'm still interested in merging a carve-out driver[1], since it seems to be in every vendor BSP and got asked again last week. I remember from our discussion that for new heap types to be merged, we needed a kernel use-case. Looking back, I'm not entirely sure how one can provide that given that heaps are essentially facilities for user-space. Am I misremembering or missing something? What are the requirements for you to consider adding a new heap driver? Thanks! Maxime 1: https://lore.kernel.org/dri-devel/20240515-dma-buf-ecc-heap-v1-1-54cbbd049511@xxxxxxxxxx/
