A while back kvm got support for memory slots which allow read access and vmexit on write access. Flash emulation needs this, and I think it is possible to also implement the "read from rom and write to memory" mode using that. cheers, Gerd _______________________________________________ SeaBIOS mailing list [email protected] https://www.coreboot.org/mailman/listinfo/seabios
