In the commit 54c4ea8f3ae6 ("hw/core/machine-smp: Deprecate unsupported
'parameter=1' SMP configurations"), the SMP related item is put under
the section "User-mode emulator command line arguments" instead of
"System emulator command line arguments".
-smp is a system emulator
The current implementation treats emulated memory devices, such as
CXL1.1 type3 memory, as normal DRAM when they are emulated as normal memory
(E820_TYPE_RAM). However, these emulated devices have different
characteristics than traditional DRAM, making it important to
distinguish them. Thus, we
When a memory device, such as CXL1.1 type3 memory, is emulated as
normal memory (E820_TYPE_RAM), the memory device is indistinguishable
from normal DRAM in terms of memory tiering with the current implementation.
The current memory tiering assigns all detected normal memory nodes
to the same DRAM

reverse-debugging. Often the issue being debugged appears near the end of
the trace, so it is important for performance to keep snapshots close to
the end.

It would be good to mention PAPR section numbers suggesting the same.

Hi Daniel, Paolo,
Here my last questions before wrapping up and send v4, or maybe call off
my attempt to add RAPL interface in QEMU.

Count number of tb and insn executed using a conditional callback. We
ensure the callback has been called expected number of time (per vcpu).

Extend plugins API to support callback called with a given criteria
(evaluated inline).
Added functions:
- qemu_plugin_register_vcpu_tb_exec_cond_cb
- qemu_plugin_register_vcpu_insn_exec_cond_cb
They expect as parameter a condition, a qemu_plugin_u64_t (op1) and an
immediate (op2). Callback is
This series implement two new operations for plugins:
- Store inline allows to write a specific value to a scoreboard.
- Conditional callback executes a callback only when a given condition is true.
The condition is evaluated inline.
It's possible to mix various inline operations (add, store)

This won't work, as needed. Announce timer can't be enabled, because
it is set in post_load function. Therefore announce callbacks break
the replay, when virtio-net is used with snapshots.
