When SEV is enabled, the hardware encryption engine uses a tweak such
that the two identical plaintext at different location will have a
different ciphertexts. So swapping or moving a ciphertexts of two guest

The command can be used by libvirt to query the SEV capabilities.

target_mprotect/target_munmap return value goes through get_errno at the

Hello,
this series adds linux-user support for target/xtensa.
It starts with a small cleanup for xtensa registers dumping.
It adds support for debugging linux-user process with xtensa-linux-gdb
(as opposed to xtensa-elf-gdb), which can only access unprivileged
registers.
It then enables MTTCG for
System emulation should provide access to all registers, userspace
emulation should only provide access to unprivileged registers.
Record register flags from GDB register map definition, calculate both
num_regs and num_core_regs if either is zero. Use num_regs in system
emulation, num_core_regs in
xtensa_cpu_dump_state outputs CPU physical registers as is, without
synchronization from current window. That may result in different values
printed for the current window and corresponding physical registers.
Synchronize physical registers from window before dumping.
