Subject: [PATCH v2 04/13] start_vm: Add RISC-V 64-bit support
Date: Mon, 13 Jan 2020 09:28:09 +0100 [thread overview]
Message-ID: <023ab52c3c89d2960a7474c3105767890c7763e1.1578904098.git.jan.kiszka@siemens.com> (raw)

This arch is still special in that QEMU does not support directly
booting the kernel via "-kernel". Rather, you need to install opensbi on
the host and load fw_jump.elf as kernel while the actual kernel goes at
a magic address via the loader device.
