I'd prefer to keep fw_cfg out of the picture, and I think we can do it without too much problems. We have a TSEGMB (tseg memory base) register. qemu doesn't implement it (but I think you can write to it and read back what you've written). We could make qemu update that register in case "11b" is written to the tseg size. The firmware then can read TSEGMB and figure whenever a large tseg is supported and if so how big it is. cheers, Gerd _______________________________________________ edk2-devel mailing list [email protected] https://lists.01.org/mailman/listinfo/edk2-devel
