Re: linux-user cannot allocate stack memory on riscv64 host due to non-zero guest_base

[Andreas Schwab]

Please follow https://en.opensuse.org/openSUSE:RISC-V#QEMU_system_emulation
to start the JeOS-efi image.  When logged in:

# zypper rm qemu-linux-user-riscv
# zypper in qemu-linux-user

Then you can run qemu-riscv64 inside:

# qemu-riscv64 -d page hello.riscv64 
host mmap_min_addr=0x10000
Locating guest address space @ 0x3ee000
