hmm it might also be possible to utilize shared memory for malloc/realloc/free such that we directly use host memory instead of pre-allocated memory tho im not sure how this might...

hmm alright so according to https://lwn.net/Articles/808807/ it would be safe to assume that this would transform -m xyzM such that it specifies the amount of memory to `reserve`, and then...

in regards to host dynamic memory, probs related to https://github.com/LekKit/RVVM/issues/76

hmm, so to be clear, this would allow, for example something like ``` RVVM - KERNEL - MALLOC - request memory from host and remap as contig via mmio -...

yea, the vm (both qemu and rvvm) will RESERVE the memory but not COMMIT it upfront (eg if we -m 8 GB it will reserve 8 GB but it will...
