Changelog: https://wiki.qemu.org/ChangeLog/11.0 Note: - Support for all 32-bit host systems has been removed. - Support for microblazeel has been folded into the microblaze target Qemu v11.0.0 drops 32-bit support for hosts, all qemu builds must now be 64-bit. Hosts running 64-bit qemu builds can still emulate 32-bit targets. Confusingly, the qemu package is also capable of being built and running on buildroot hosts, and targets. In any case, qemu only supports running on 64-bit hosts (which may be buildroot targets), so adjust BR2_PACKAGE_QEMU_ARCH_SUPPORTS_TARGET to indicate no support for 32-bit buildroot targets, and drop configs for architectures like BR2_arm that are implicitly 32-bit only. Separately, the qemu microblazeel target was removed with commit 46a25ae3f0e75e230c06e21435850b1cd1c44f07, as the microblaze (qemu) target supports both endiannesses, so that's fixed up in the package Makefile as well.

QEMU is a generic and open source machine emulator and
|
|
virtualizer.
|
|
|
|
When used as a machine emulator, QEMU can run OSes and
|
|
programs made for one machine (e.g. an ARM board) on a
|
|
different machine (e.g. your own PC). By using dynamic
|
|
translation, it achieves very good performance.
|
|
|
|
When used as a virtualizer, QEMU achieves near native
|
|
performances by executing the guest code directly on the
|
|
host CPU. QEMU supports virtualization when executing under
|
|
the Xen hypervisor or using the KVM kernel module in
|
|
Linux. When using KVM, QEMU can virtualize x86, server and
|
|
embedded PowerPC, and S390 guests.

Enable user mode network stack, which is the default
|
|
networking backend. It requires no administrator privileges
|
|
and generally is the easiest to use but has some
|
|
limitations:
|
|
|
|
- there is a lot of overhead so the performance is poor;
|
|
- in general ICMP does not work (can't ping from/to a guest)
|
|
- on Linux hosts, ping does work from within the guest, but it
|
|
needs initial setup by root (once per host)
|
|
- the guest is not directly accessible from the host or the
|
|
external network
|
|
|
|
User Networking is implemented using "slirp", which provides a
|
|
full TCP/IP stack within QEMU and uses that stack to implement
|
|
a virtual NAT'd network.
|
|
|
|
Notice that this option does not disable other networking
|
|
modes.
