Hello,
I'm trying to update this patch for 2017 as I have the same issue as the author in that I can't use the KVM virtual keyboard and a physical keyboard at the same time: https://patchew.org/Seabios/20171215100946.58298-1-stef.van.os@prodrive-tech...
I have implemented a linked list as recommended but this has not worked as expected. Assuming I have not made an obvious mistake, I think maybe this patch is not working because I'm using the wrong malloc. Which one should I be using?
There is some documentation in docs/Memory_Model.md (also at https://www.seabios.org/Memory_Model ). Since the usb keyboard code is using GET_GLOBAL() to dereference pointers, the memory would likely need to be allocated with malloc_fseg().
