Hi, There are several ideas for DT improvements. Please check if they are reasonable, and any comments are welcome. I would let Mingliang (CCed) share more details if needed.
1) Improve search algorithm performance: Is the binary search tree or other algorithm better than current algorithm? 2) Reduce DTB space: when use one DTB to support multiple boards, the image is quite big (e.g, ~39MB space for 100 configurations), and some compression algorithm can reduce the space a lot (e.g, from 39MB to 7MB). Shall we have such compression support for DTB? And it can be helpful if we can have more efficient compression algorithm. 3) Define specific rule for properties: The property value (FDT_PROP_DATA) itself occupies only ~50% of the total DTB space. And the property of each node is different and the private property name length is too long, for example: “freq-autodown-baseaddress-num” in dt_strings. It seems more reasonable that the property value should occupies more than 70% of the total DTB space. It can probably be achieved to define some rules to restrict the length of property name, etc. Thanks, Jammy _______________________________________________ boot-architecture mailing list boot-architecture@lists.linaro.org https://lists.linaro.org/mailman/listinfo/boot-architecture
