trace: Remove deprecated 'vcpu' field from QMP trace events

2024-06-04T09:53:43Z

'vcpu' fields are deprecated since commit 5485e52a33 ("qapi: make the vcpu parameters deprecated for 8.1"), time to remove them. Signed-off-by: Philippe Mathieu-Daudé Reviewed-by: Michael S. Tsirkin Reviewed-by: Markus Armbruster Message-Id: <20240530071548.20074-3-philmd@linaro.org>

tracing: install trace events file only if necessary

It is not useful when configuring with --enable-trace-backends=nop. Signed-off-by: Carlos Santos Signed-off-by: Stefan Hajnoczi Message-ID: <20230408010410.281263-1-casantos@redhat.com>

meson: Replace softmmu_ss -> system_ss

2023-06-20T08:01:30Z

We use the user_ss[] array to hold the user emulation sources, and the softmmu_ss[] array to hold the system emulation ones. Hold the latter in the 'system_ss[]' array for parity with user emulation. Mechanical change doing: $ sed -i -e s/softmmu_ss/system_ss/g $(git grep -l softmmu_ss) Signed-off-by: Philippe Mathieu-Daudé Reviewed-by: Richard Henderson Message-Id: <20230613133347.82210-10-philmd@linaro.org> Signed-off-by: Richard Henderson

trace: remove control-vcpu.h

Now we no longer have vcpu controlled trace events we can excise the code that allows us to query its status.

trace: remove code that depends on setting vcpu

2023-06-01T15:05:05Z

Now we no longer have any events that are for vcpus we can start excising the code from the trace control. As the vcpu parameter is encoded as part of QMP we just stub out the has_vcpu/vcpu parameters rather than alter the API.

trace: remove vcpu_id from the TraceEvent structure

2023-06-01T15:05:05Z

This does involve temporarily stubbing out some helper functions before we excise the rest of the code.

trace-events: remove the remaining vcpu trace events

2023-06-01T15:05:05Z

While these are all in helper functions being designated vcpu events complicates the removal of the dynamic vcpu state code. TCG plugins allow you to instrument vcpu_[init|exit|idle]. We rename cpu_reset and make it a normal trace point.

trace: Do not try to include QMP commands in user emulation binaries

2023-02-27T21:29:01Z

QMP is not available on user emulation; there is not monitor. Besides, since commit a0e61807a3 ("qapi: Remove QMP events and commands from user-mode builds") we don't generate the qapi-commands-trace.h header in a user-emulation-only build. Remove the QMP trace commands from qemu-user binaries. Signed-off-by: Philippe Mathieu-Daudé Acked-by: Richard Henderson Message-Id: <20221220150417.26751-1-philmd@linaro.org>
