If the user/mgmt app passed in a set of pre-opened FDs for eBPF RSS,
then it is expecting QEMU to use them. Any failure to do so must be
considered a fatal error and propagated back up the stack, otherwise
deployment mistakes will not be detectable in a prompt manner. When
not using pre-opened FDs, then eBPF RSS is tried on a "best effort"
basis only and thus fallback to software RSS is valid.

The eBPF code is currently reporting error messages through trace
events. Trace events are fine for debugging, but they are not to be
considered the primary error reporting mechanism, as their output
is inaccessible to callers.
This adds an "Error **errp" parameter to all methods which have
important error scenarios to report to the caller.

A design pattern of

The net/af-xdp.c code is enabled when the libxdp library is present,
however, it also has direct API calls to bpf_xdp_query_id &
bpf_xdp_detach which are provided by the libbpf library.
As a result if building with --disable-libbpf, but libxdp gets
auto-detected, we'll fail to link QEMU
/usr/bin/ld: libcommon.a.p/net_af-xdp.c.o: undefined reference to symbol 'bpf_xdp_query_id@@LIBBPF_0.7.0'
There are two bugs here
* Since we have direct libbpf API calls, when building
net/af-xdp.c, we must tell meson that libbpf is a
dependancy, so that we directly link to it, rather
than relying on indirect linkage.
* When must skip probing for libxdp at all, when libbpf
is not found, raising an error if --enable-libxdp was
given explicitly.

34e5e1 refactored the plugin context initialization. After this change,
tcg_ctx->plugin_insn is not reset inconditionnally anymore, but only if
one plugin at least is active.
When uninstalling the last plugin active, we stopped reinitializing
tcg_ctx->plugin_insn, which leads to memory callbacks being emitted.
This results in an error as they don't appear in a plugin op sequence as
expected.
The correct fix is to make sure we reset plugin translation variables
after current block translation ends. This way, we can catch any
potential misuse of those after a given block, in more than fixing the
current bug.

We try to avoid using cpu_loop_exit_atomic as it brings in an all-core
sync point. However on some cpu/kernel/benchmark combinations it is
starting to show up in the performance profile. To make it easier to
see whats going on add tracepoints for the slow path so we can see
what is triggering the wait.
It seems for a modern CPU it can be quite a bit, for example:

fixed cross-modifying code handling, but did not add a test. The

Add a test to make sure there are no regressions.

Testing non-auto built docker containers (i.e. custom built compilers)
is a bit fiddly as you couldn't continue a build with a previously
locally built container. While you can play games with REGISTRY its
simpler to allow a NOFETCH that will go through the cached build
process when you run the tests.

ASPEED shipped default flash of fmc_cs0 and fmc_cs1 were "w25q80bl" and

The fmc_cs0 was connected to AST1030 A1 internal flash and the fmc_cs1 was
connected to external flash. The internal flash could not be changed because
it was placed into AST1030 A1 chip. Users only can change fmc_cs1 external
flash.
So far, only supports to set the default fmc_model for all chip select pins.
In other words, users cannot set the different default flash model for
