Hi, thank you for your reply. Harald may be in flight now :) > One question to your SoCs though - do they have SRAM? usable and > sufficient for graphics buffers?

All Samsung SoCs have no SRAMs for graphic buffers, just having system memory. And what is worse, in case of 2 system memory banks, some kinds of hardware need to allocate buffers to improve performance at each bank separately. This is just a kind of sample, Samsung SoCs have many special cases. (Of course, we are trying to add IOMMU to resolve buffer issues at next SoCs products) Best Regards -- Jinsung, Yang <jsgood.yang@xxxxxxxxxxx> AP Development Team System LSI, Semiconductor Business SAMSUNG Electronics Co., LTD -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
