Alistair Francis	e1f49dc888	target/riscv: Implement checks for hfence ... Call the helper_hyp_tlb_flush() function on hfence instructions which will generate an illegal insruction execption if we don't have permission to flush the Hypervisor level TLBs. Backports commit 2761db5fc20943bbd606b6fd49640ac000398de6 from qemu	2021-02-25 12:03:57 -05:00
Lioncash	b6f752970b	target/riscv: Initial introduction of the RISC-V target ... This ports over the RISC-V architecture from Qemu. This is currently a very barebones transition. No code hooking or any fancy stuff. Currently, you can feed it instructions and query the CPU state itself. This also allows choosing whether or not RISC-V 32-bit or RISC-V 64-bit is desirable through Unicorn's interface as well. Extremely basic examples of executing a single instruction have been added to the samples directory to help demonstrate how to use the basic functionality.	2019-03-08 21:46:10 -05:00
